Description

FORMING APPARATUS FOR LINE TYPE METAL MEMBER}

The present invention relates to a line-shaped metal material forming apparatus, and more particularly to a molding device for reducing the volume of the metal material formed in the form of a tape or wire.

In general, metal wires are manufactured in various sizes and used in various fields. Such metal wires include general wires or twisted wires in which several wires are twisted, and special metal wires having special physical properties. In the case of special metal wires, finely shaped metal wires are processed in accordance with desired conditions to enhance corrosion resistance, wear resistance, corrosion resistance, discoloration, oxidation, and the like.

Among these metal wires, metal wires having a thin thickness or diameter are manufactured by forming a thin wire through a molding after purchasing a thick base wire wire wound on a drum. Of course, the above-mentioned base material wire is sold by winding the drum in the form of a thick tape or a thick wire.

Such a base material wire, that is, a thick metal wire, is thinly formed by a metal wire forming apparatus composed of a feeder for rotatably fixing the drum, a rolling mill for rolling the metal wire, and a winding machine for winding the rolled metal wire on the bobbin. At this time, the thick metal wire is drawn out from the drum in which the hollow is formed, is thinly formed through a rolling mill, and then wound in a bobbin rotated in a winding machine. Then, it is sold in a state wound in the bobbin or manufactured by a special metal wire again by a separate equipment and then sold.

On the other hand, the winding machine can be rolled evenly to the bobbin rotating the metal wire in the fixed position because the idler roller of the Travis installed in front to supply the rolled metal wire while moving left and right. That is, a winder can wind a metal wire horizontally to a bobbin by trevis.

However, in the apparatus for forming a general metal wire, when a metal wire thinly formed through a rolling mill is manufactured as a special metal wire, the rolled metal wire cannot be continuously processed in a special process, but must be carried to a special processing facility to perform special processing. . That is, there is a problem in that the metal wire that is thinly formed through the rolling mill cannot be specially processed continuously.

In more detail, when the rolled metal wire is to be manufactured as a special metal wire, the metal wire firstly rolled and wound on the bobbin is transported to a special processing device, and then withdrawn from the bobbin and specially processed through a special processing plant. Then it must be wound again in another bobbin. Therefore, the general metal wire has to be repeatedly carried out by repeating the bobbin winding during special processing, and also has to be inconvenient to transport the rolled metal wire bobbin to the loading place and then to the place where the special processing device is installed. .

In addition, as a special processing device is generally used a heat treatment device for heat treatment while passing the metal wire inside. However, since the heat treatment apparatus generates high temperature heat during the process and cools down the process, there is a problem in that deformation occurs due to temperature change.

In addition, while the hollow drum on which the above-mentioned base material wire is wound is formed in various lengths according to the seller, the feeder is configured to fix only a drum of a set size, so when purchasing a small drum, the drum is formed by hanging a separate pedestal on the feeder. There is a problem in that it needs to be rotatably fixed or a drum of a size suitable for the size of the feeder must be separately requested. In addition, the hollow of the drum penetrates because the feeder rotatably fixes the drum through the through shaft penetrating the drum. If formed larger than the shaft there is also a problem that the rotating drum flows in the through shaft and excessively tension the metal wire to cause a defect or to cut while pulling the drawn metal wire.

In addition, a phenomenon in which the rotational speed of the drum is faster or slower than the rotational speed of the winding machine which draws out the metal wire from the drum may occur and the metal wire may be entangled or cut during the process.

In addition, since the separation width of the rollers of the rolling mill consisting of a pair of roller pairs can not be finely adjusted, there is also a problem in that the thickness of the metal wire can not be precisely molded to a desired size.

In addition, there is a problem that the thin rolled metal wire is cut because the idler roller of the Travis feeds the rolled metal wire to the winder while moving left and right in front of the winder. This is because Trevis is installed between the rolling mill and the winding machine and pulls the straight metal wire in the form of a bow strike while moving the metal wire fed straight from the rolling mill toward the winding machine from side to side through the idle roller. Cut off.

In addition, since the bobbin fixture mounted on the winder is configured not to rotatably fix the bobbins of various sizes, there is a problem in that the bobbins of various sizes cannot be fixed to the winder.

In addition, there is also a problem that the metal wire which is thinly formed in the rolling mill and supplied to the winding machine is cut when excessively tensioned due to the malfunction of the rolling mill or the winding machine or the inadvertent operation of the worker.

The present invention may further include at least one brake for detecting an excessive tension of the metal wire drawn out from the drum and wound on the bobbin of the winder to emergency stop the winder or the rolling mill.

The brake may include, for example, a master sheave in which the metal wire is wound; An undersheave spaced apart from the master sheave and winding the metal wire in an oval shape together with the master sheave; A moving block moving to the master sheave by the metal wire being tensioned by being elliptical with the under sheave; A guider for guiding movement of the moving block; It may be configured to include; a power circuit breaker for detecting the movement of the under-sheave moved by the guider with the moving block to cut off the power supply of the winding machine or the rolling mill.

The power circuit breaker may include, for example, a protrusion protruding from the moving block to move together with the moving block; A spiral spiral rail having a groove shape into which the protrusion is inserted, formed on an outer circumferential surface thereof and pivoting as the spiral rail rotates by the movement of the protrusion; And a switching member connected to the shaft in a contact or non-contact manner and switching the power supply switch of the winding machine or the rolling mill while interlocking with the shaft.

The brake unit may be configured in plural and be installed adjacent to at least one of the rolling mill and the winding machine.

In the present invention as described above, the metal wire rolled in the rolling mill is continuously surface-treated through the surface treatment machine without interruption, so that the rolled metal wire can be specially processed immediately, and the deformation prevention means is provided in the surface treatment machine. Flexural deformation of the lead-out pipe by heat shrinkage can be prevented.

In addition, since the rotation speed of the drum may be adjusted through the rotation speed control means, the drum may be rotated faster than the winding machine so that the metal wires may be tangled or rotated later than the winding machine to prevent the metal wires from being cut.

Moreover, since the drum speed is adjusted through the adjusting member to support the drum, the speed of the drum can be adjusted easily and stably.

In addition, the distance between the one roller and the other roller can be adjusted while moving the one roller of the rolling mill through the adjuster, it is possible to easily adjust the volume of the metal wire, that is, the thickness or thickness.

In particular, as the pivot screw of the adjuster is finely rotated by the screw thread, the one side roller is finely moved together with the moving disk, so that the moving distance of the one roller can be precisely adjusted, and in addition, the elastic body makes the pivot screw elastic through the moving disk. Since it is supported, the pivot screw, which has been rotated, can be prevented from being loosened while being rotated when the rolls are rotated.

In addition, when a plurality of rolling mills are formed, the metal wires drawn from the drum may be gradually thinned while rolling in steps, thereby improving the quality of the formed metal wires.

In addition, since the surface passivation of the metal wire with the hydrogen-based surface treatment proceeds smoothly passivation of the metal wire can prevent oxidation and discoloration of the metal wire.

In addition, since the bobbin is fixed to the insertion shaft of the winder by the fastener in which the winders are adjusted to each other, not only can bobbins of various lengths be fixed to the winder, but also the metal wires are horizontally held by the horizontal winding means. Winding with can prevent deflection winding of the metal wire.

In addition, since the horizontal winding means is configured to wind the metal wire while reciprocating to the section in which the bobbin is set by the shuttle and the driver, the metal wire can be wound on the bobbin without any gap.

On the contrary, since the reciprocating roller for guiding the metal wire to the bobbin may be configured to wind the metal wire while reciprocating from one side of the bobbin, the metal wire may be wound horizontally without moving the bobbin, and the gear engagement type Precise operation control is possible by the structure.

Furthermore, the brake detects excessive tension of the metal wire to be molded and emergency stops the drive of the winding machine and / or the rolling mill through the power circuit breaker, thereby preventing the metal wire from being cut by the malfunction of the winding machine or the rolling mill. When the power circuit breaker is configured to operate during the movement of the machine, the excessive tension of the metal wire can be checked mechanically. Furthermore, when the shaft having the protrusion and the spiral rail is configured to drive the switching member, the switching member can be operated mechanically. Not only can the operation of the member be realized semipermanently, but also the switching member can be operated in a non-contact manner when the switching member is composed of a conductor and a hall element.

On the contrary, when the power circuit breaker is configured as a proximity sensor that detects the position of the under-sheave, the power circuit breaker can be easily configured.

In addition, when a plurality of brakes are configured, the excessive tension of the metal wire can be detected more accurately, and therefore, the metal wire can be formed more stably.

Hereinafter, with reference to the accompanying drawings of the line-shaped metal material forming apparatus according to an embodiment of the present invention.

Referring to Figure 1, the line-shaped metal material forming apparatus according to an embodiment of the present invention, as shown in the feeder 10, at least one rolling mill 20 and the winding machine 40, the surface treatment, and the deformation preventing means ( 35).

The feeder 10, the rolling mill 20, and the winding machine 40 are installed on a member such as the work table WD, as shown for convenience of work, and are sequentially arranged and aligned from one side to the other side as shown. . The feeder 10, the rolling mill 20, and the winding machine 40 are provided with a plurality of idle rollers IR as shown between each other. The idle roller IR prevents the metal wire 2 from sagging downward while guiding the metal wire 2 as shown.

The feeder 10 is installed at the tip of the work table WD, as shown, and the drum 1 on which the metal wire 2 is wound is rotatably fixed. The feeder 10 supplies the metal wire 2 to the winder 40 as shown while rotating the drum 1. At this time, the metal wire 2 is a rolling mill 20, a brake 50 to be described later, another rolling mill 20, a cleaner 60 to be described later, the atmosphere furnace 30 and the atmosphere furnace 30 to be described as shown It is supplied to the bobbin BB of the winder 40 through another brake 50 of the upper phase.

The rolling mill 20 receives and feeds the metal wire 2 drawn out of the drum 1 from the feeder 10 as shown. That is, the rolling mill 20 reduces the volume of the metal wire 2 and thinly shapes it. Such a rolling mill 20 may be composed of a plurality as shown in the spaced apart in series. As such, when the rolling mills 20 are installed in series, the first rolled metal wire 2 may be rolled secondly. Of course, the rolling mill 20 may roll the metal wires 2 more times when provided in plural. That is, the rolling mill 20 may roll the metal wire 2 several times when composed of several. Therefore, the metal wires 2 are gradually formed by tapering step by step. Of course, the metal wire 2 is manufactured in good quality to prevent excessive molding.

Rolling mill 20 is composed of a pair of roller pairs facing each other as shown, and performs rolling as the roller is rotated by the drive motor 21.

The winder 40 performs the final process on the atmosphere furnace 30 as shown. That is, the winder 40 winds the bobbin BB the metal wire 2 which passed through the rolling mill 20 through the atmosphere furnace 30 and the brake 50. This winding machine 40 rotates the bobbin BB as shown to wind the metal wire 2 via the above-mentioned members to the bobbin BB. Therefore, the winder 40 provides the metal wire 2 in which the molding process is completed in a wound form.

The winder 40 pulls the metal wire 2 while rotating the bobbin BB. Thus, the winder 40 pulls out the metal wire 2 from the drum 1 of the feeder 10. That is, the winder 40 pulls out the metal wire 2 of the drum 1, winding the metal wire 2 to bobbin BB.

On the other hand, the surface treatment machine described above is surface-treated the metal wire (2) is rolled in the rolling mill 20 is reduced in volume. The surface treatment machine converts the surface characteristics of the metal wire 2 by reacting the metal wire 2 with a chemical in a liquid or gaseous phase. That is, the surface treatment machine improves the material properties on the surface of the metal wires 2 and processes the metal wires 2 for special purposes.

Such a surface treatment machine may be configured, for example, with an atmosphere furnace 30 and withdrawal pipes 31 and 33 as shown. The atmosphere furnace 30 passes the metal wire 2 at a temperature that prevents deterioration in a state in which the metal wire 2 is isolated from the outside. The atmosphere furnace 30 is filled with an atmosphere gas that reacts with the metal wire 2 and passivates the film of the metal wire 2. Therefore, the atmosphere furnace 30 heat-treats the metal wire 2 in a gas atmosphere to change the surface characteristics of the metal wire 2.

The draw-out pipes 31 and 33 are composed of a draw-in pipe 31 provided at the inlet side of the atmosphere furnace 30 and a draw-out tube 33 provided at the outlet side to pass the metal wire 2 into the atmosphere furnace 30. Penetrate into. That is, the draw-out pipes 31 and 33 are pipes that allow the metal wires 2 to pass through the atmosphere 30 in a straight line.

At this time, the atmosphere furnace 30 heats the metal wire 2 to generate a high temperature heat to relax the draw-out pipes 31 and 33, while cooling after operation to generate the bending deformation while shrinking the draw-out pipes 31 and 33. Let. In addition, since the atmosphere 30 is cooled while the internal pressure is lowered, the draw-out pipes 31 and 33 are further contracted to generate deformation.

The deformation preventing means 35 is provided in the inlet pipe 31 and the outlet pipe 33, respectively, to prevent the deflection deformation while the outlet pipes 31 and 33 are contracted according to the temperature change of the atmosphere furnace 30. The deformation preventing means 35 may include a stopper ring 35a and an elastic member 35b as shown in an enlarged view.

The stopper ring 35a is coupled to the ends of the draw-out pipes 31 and 33 and is fixed in a flange form by the fixing bolt 35c. The elastic member 35b is fitted between the draw-out pipes 31 and 33 and is placed between the atmosphere furnace 30 and the stopper ring 35a so that the draw-out pipes 31 and 33 move toward the atmosphere furnace 30 by elasticity. Suppresses contraction. The stopper ring 35a adjusts the elastic force of the elastic member 35b while adjusting the distance to the atmosphere furnace 30 by the fixing bolt 35c.

The elastic member 35b may be configured as a coil spring as shown.

Therefore, the draw-out pipes 31 and 33 are suppressed from shrinkage by the stopper ring 35a and the elastic member 35b when the atmosphere furnace 30 is changed in temperature, especially during cooling, so that bending deformation is prevented and the metal wire ( 2) penetrates into the atmosphere furnace 30 in a straight state.

Meanwhile, the atmosphere furnace 30 may, for example, heat-treat the metal wire 2 with a reducing atmosphere using a hydrogen base to prevent oxidation of the metal wire 2. That is, the atmosphere furnace 30 may be configured to heat-treat the metal wire 2 with a hydrogen atmosphere. Therefore, the metal wire 2 is prevented from discoloring even if it is exposed to the air for a long time.

Alternatively, the surface treatment machine may be configured as a tub (not shown) in which a chemical component of a liquid, not shown, is stored to immerse the metal wire 2 in a immersion manner. In this case, the chemical component filled in the bath may be a metal plating solution or a plastic-based coating solution, and alternatively, the chemical component may be a conventional electrolyte for anodizing the surface of the metal wire 2. Since such a surface treatment can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

On the other hand, the above-described brake 50 may be selectively employed. The brake unit 50 detects that the metal wire 2 drawn out from the drum 1 and wound on the bobbin BB of the winder 40 is excessively tensioned, and thus the winder 40 and / or the rolling mill 20 are closed. It is an emergency stop member. As shown in FIG. 2, the brakes may be configured in plural and may be installed in the adjoining state with the rolling mill 20 and the winding machine 40. Such a brake 50 can be installed adjacent to members other than the rolling mill 20 and the winding machine 40 as needed. Alternatively, the brake 50 may be configured as one and may be installed adjacent only to the winder 40 or the rolling mill 20.

The brake is provided with a master sheave 51 and an under sheave 52 which will be described later as enlarged. The master sheave 51 and the under sheave 52 are vertically spaced apart as shown, and the metal wires 2 drawn out from the drum 1 and supplied to the winder 40 are wound in an elliptical shape. The under sheave 52 rises toward the master sheave 51 as shown, when a tensile force is applied to the metal wire 2 and the elliptically wound metal wire 2 is tense. At this time, the under sheave 52 rises as the diameter of the ellipse formed by the metal wire 2 is reduced by the tensile force. That is, the under sheave 52 rises by the tension of the metal wire 2.

Here, the above-described metal wire (2) is a tensile force is generated by the malfunction of the rolling mill 20 or the winding machine (40). That is, the metal wire 2 is pulled by the rolling mill 20 or the winder 40 when the rolling mill 20 or the winder 40 is stopped or operated slowly, the tensile force acts. Therefore, as the metal wire 2 is pulled by the external force, the elliptical diameter is reduced while raising the under sheave 52.

On the other hand, the above-described cleaner 60 may be selectively employed. The cleaner 60 cleans the metal wire 2 inserted into the atmosphere furnace 30 after rolling is completed as shown. Such a cleaner 60 may include, for example, a fiber cotton cloth 61 disposed in close contact with the upper and lower portions of the metal wire 2 and a weight 63 for pressing the cotton cloth 61. Can be.

The cotton cloth 61 presses the metal wire 2 by the load of the weight 63. Therefore, the surface of the metal wire 2 is washed by the cotton cloth 61 while being supplied to the atmosphere furnace 30. Of course, since the impurities in the rolling process are removed by the cotton cloth 61, the metal wire 2 is smoothly surface-treated in the atmosphere furnace 30.

Referring to FIG. 2, the drum 1 is formed in a bobbin shape as shown in order to have a hollow 1a. The drum 1 is fixed to the feeder 10 as shown in the drawing while supplying the metal wire 2.

The feeder 10 may be configured to include, for example, a cone-shaped cone 11, a bracket 12, another cone 13, a screw shaft 15, and a support 17 as shown. One side cone 11 is inserted into one side of the hollow (1a) formed in the drum (1) as shown to rotatably support one side of the drum (1). One side cone 11 may support one side of the drum 1 in a state connected to the work table (WD) through the bracket 12 as shown.

The other side cone 13 is inserted into the other side of the hollow (1a) formed in the drum (1) as shown to rotatably support the other side of the drum (1). The other side cone 13 is connected to one end of the screw shaft 15 as shown.

The screw shaft 15 has a handle 15a at the other end as shown, and is rotated by the handle 15a while being supported by the support 17. The screw shaft 15 moves the other side cone 13 while moving horizontally during rotation. Accordingly, the other side cone 13 corresponds to the length of the various drums 1 as the distance between the one side cone 11 fixed to the bracket 12 becomes closer or further away. That is, the other side cone 13 is rotatable and fixed to the feeder 10 of the drum 1 of various lengths while being moved.

Here, since the one side cone 11 and the other side cone 13 is formed in a conical shape as shown, the contact area with both sides of the drum 1 is minimized. Thus, the one side cone 11 and the other side cone 13 rotatably supports the drum 1.

The support 17 is formed in a plate shape as shown, so that the screw shaft 15 penetrates. This support 17 is formed with a female thread at the portion through which the screw shaft 15 penetrates. Thus, the screw shaft 15 is screwed to the support 17. Of course, the screw shaft 15 is moved horizontally while being rotated in a screwed state. That is, the support base 17 supports the screw shaft 15 in a movable state.

On the other hand, the feeder 10 may be configured to further include a rotation speed control means. The rotation speed control means is an element that provides a friction force to the drum 1 to control the rotation speed of the drum 1 to a speed corresponding to the rotation speed of the winder 40 described above.

The rotational speed control means is integrally extended to one side cone 11 to press the ends of the cone shaft (11a) and the cone shaft (11a) penetrating through the shaft hole (12a) formed in the bracket 12, the one side cone (11) It includes an adjusting member 14 for lever movement.

The shaft hole 12a is formed to have an inner diameter larger than the outer diameter of the cone shaft 11a to provide a working point and a space in which the cone shaft 11a can be levered. Therefore, the cone shaft 11a levers the one side cone 11 about the shaft hole 12a while the end is pressed.

The adjusting member 14 may include a lever sheave 14a, a pressure rope 14b, and a turnbuckle 14c.

The lever sheave 14a is coupled to the end of the cone shaft 11a, and lever movements around the shaft hole 12a at the other side of the one side cone (11).

The pressing rope 14b is connected to the lever sheave 14a, and while the length is adjusted, the lever sheave 14a is pressed to move the lever sheave 14a and the one side cone 11 around the shaft hole 12a.

The turnbuckle 14c is coupled to the bracket 12 in a state connected to the pressure rope 14b, and adjusts the tension of the pressure rope 14b while the length is stretched by rotation. The turnbuckle 14c may be composed of a stud bolt (SB) and an adjustment nut (NT) coupled to the bracket 12 and one end is connected to the pressure rope (14b) as shown. That is, the turnbuckle 14c adjusts the tension of the pressure rope 14b by raising and lowering the stud bolt SB while the adjusting nut NT rotates.

Therefore, the one side cone 11 descends about the shaft hole 12a as the lever sheave 14a rises by the pressurizing the rope 14b through the adjustment of the turnbuckle 14c, and with the drum 1 As the frictional force increases, the rotational speed of the drum 1 is adjusted.

Meanwhile, the pressing rope 14b may be connected to the turnbuckle 14c by a buffer member 14d such as a coil spring as shown. Therefore, the pressing rope 14b may press the lever sheave 14a while being buffered by the shock absorbing member 14d during tension adjustment through the turnbuckle 14c.

Referring to FIG. 3, the lever sheave 14a is formed in a pulley shape and coupled to an end of the cone shaft 11a. In addition, the pressure rope 14b is wound around the lever sheave 14a in a state where one end is fixed to the bracket 12, and the other end is connected to the turnbuckle 14c.

Referring to FIG. 4, the rolling mill 20 is, for example, a frame 23, one roller R1 and the other roller R2 rotated by the aforementioned driving motor 21, and an adjuster described below. It can be configured to include.

The frame 23 may be composed of, for example, a base 23b on which the post 23a is erected and an upper 23c shielding the top of the post 23a as shown. Therefore, the frame 23 has a space therein by the base 23b, the posts 23a, and the upper 23c. As shown in the inner space of the frame 23, one roller R1 and the other roller R2 are embedded.

One roller R1 and the other roller R2 face each other while forming a vertical as shown. One side roller (R1) and the other side roller (R2) is connected to the above-described drive motor 21 by a belt or chain (not shown) is rotated in a state facing the drive force of the drive motor 21 while pressing the metal wire (2) do. Therefore, the one side roller R1 and the other side roller R2 roll the metal wire 2.

The other roller R2 is rotatably inserted into the bearing BR of the fixed disk 28 as shown. The fixed disk 28 is fixed to the base 23b or the post 23a of the frame 23 by welding or bolting. Therefore, the other roller R2 cannot move.

Here, the above-mentioned adjuster is a member which adjusts the reduced volume of the metal wire 2 by moving one side roller R1. Such an adjuster may comprise, for example, a pivot screw 25 and a movable disk 27 as shown.

Pivot screw 25 is provided with a handle 25a at one end as shown. The pivot screw 25 has the other side vertically penetrated and fixed to the upper 23c of the frame 23 and pivotally rotated by the handle 25a.

The movable disk 27 is disposed above the fixed disk 28 as shown. The movable disk 27 has a ring-shaped nut 27a which is screwed with the other end of the pivot screw 25 is fixed to the upper part by welding or bolting. The moving disk 27 is fixed through the bearing BR as shown. Thus, the movable disk 27 is rotatably inserted into the bearing BR of the shaft of one side roller (R1).

The movable disk 27 is slidably fitted between the posts 23a of the frame 23. The movable disk 27 is sandwiched between the posts 23a and supported by the stopper ST of the protrusion shape protruding from the post 23a. The movable disk 27 is supported in the front by a fixing table 23d fixed to the post 23a with bolts BT. Thus, the movable disk 27 is not separated between the posts 23a.

The movable disk 27 and the fixed disk 28 may be interposed with an elastic body 29 as shown. The elastic body 29 is inserted into and fixed to the fixing pins 29a respectively attached to both rear surfaces of the movable disk 27 and the fixed disk 28.

On the other hand, the frame 23 may be provided with an idle roller (IR) as shown. The idle roller IR guides the metal wire 2 between one roller R1 and the other roller R2 as shown. At this time, the idle roller IR not only guides the metal wire 2 to the center portions of the one roller R1 and the other roller R2, but also prevents the metal wire 2 from sagging down.

Referring to Figure 5, the rolling mill 20 forms a box of a compact size as shown in the assembly.

Referring to FIG. 6, the moving disk 27 moves as a broken line when the handle 25a of the pivot screw 25 is rotated as shown. The movable disk 27 is moved up and down since the nut 27a fixed to the upper portion moves along the pivot screw 25 which pivots. At this time, the movable disk 27 moves together with the axis of one side roller R1 as shown. Therefore, the distance between the one roller (R1) and the other roller (R2) facing each other is adjusted. Of course, this reduces the volume of the metal wire 2 described above. That is, since the separation distance between the one side roller (R1) and the other side roller (R2) is controlled, the metal wire (2) is adjusted in the molding thickness (thickness or diameter).

The elastic body 29 elastically supports the movable disk 27 as shown. That is, the elastic body 29 pushes the movable disk 27 upwards. At this time, the nut 27a is pushed upward together with the movable disk 27. Therefore, the pivot screw 25 is prevented from rotating unless the handle 25a is rotated as the nut 27a is raised. That is, the pivot screw 25 does not loosen from the nut 27a after rotation. In conclusion, the elastic member is a member for locking the pivot screw 25 having completed the rotation.

Referring to FIG. 7, the brake unit 50 may include, for example, the above-described master sheave 51 and undersheave 52, a movable block BL, a guider GD, and a power circuit breaker to be described later. .

As illustrated, the master sheave 51 may be rotatably fixed to the top plate 50b fixed to the rod-shaped guider GD or tie bar TB. As illustrated, the master sheave 51 may be directly connected to the top plate 50b, or alternatively, may be rotatably fixed to a bracket or a gusset, which is not fixed to the top plate 50b. The master sheave 51 is wound with a metal wire 2 as shown.

The under sheave 52 is installed in a spaced apart state from the master sheave 51 as shown. The under sheave 52 is wound around the metal wire 2 together with the master sheave 51 as shown. The under sheave 52 has an elliptical winding of the metal wire 2 together with the master sheave 51 as shown in FIG. 1.

The movable block BL is rotatably fixed to the under sheave 52 on one side as shown. The moving block BL is fitted to the guider GD as shown and moves along the guider GD as shown by the broken line. That is, the moving block BL moves to the master sheave 51. At this time, the movable block BL moves toward the master sheave 51 together with the undersheave 52 as the elliptical metal wire 2 is tensioned and the undersheave 52 rises upward as described above.

The guider GD guides the movement of the moving block BL as shown. The guider GD may be configured as a pair and installed through both sides of the moving block BL. The guider GD is vertically fixed on the lower plate 50a spaced apart from the lower plate 50b as shown. The guider GD is the same member as the tie bar TB that supports the upper plate 50b and the lower plate 50a in a spaced state as shown.

Here, the above-described lower plate 50a is provided with a spacer SP at the lower portion as shown. The spacer SP spaces the lower plate 50a from the bottom plate BP and the upper surface of the above-described work table WD.

On the other hand, the above-described power circuit breaker detects the movement of the under sheave 52 which is moved together with the moving block BL to cut off the supply power of the above-described winding machine 40 or the rolling mill 20. Such a power circuit breaker may include, for example, a protrusion PT, a shaft 54, and a switching member SM as illustrated.

The protrusion PT is formed to protrude on the other side of the moving block BL and moves together with the moving block BL when the moving block BL moves. This protrusion PT moves in the state inserted into the spiral rail 54a which will be described later.

The shaft 54 is spaced apart from the moving block BL in an adjacent state as shown in the figure, and is rotatably fixed between the upper plate 50b and the lower plate 50a. At this time, the shaft 54 is rotatably fixed as the shafts of both ends are fitted to the upper plate 50b and the lower plate 50a as shown in the figure.

As shown in the figure, the spiral rail 54a of the groove shape into which the protrusion PT is inserted is spirally formed on the outer circumferential surface, as shown in the figure. The shaft 54 is rotated by a protrusion PT that moves up and down together with the moving block BL when the moving block BL moves as shown by a broken line. At this time, the shaft 54 is rotated as the lifting energy of the projection PT, that is, the linear moving energy acts on the spiral rail 54a to rotate the spiral rail 54a. In other words, the shaft 54 does not elevate together with the protrusion PT when the protrusion PT is lifted, and pivots about an axis of both ends by a spiral rail 54a that is rotated by the lift energy of the protrusion PT. do. Accordingly, the shaft 54 rotates when the moving block BL moves. As a result, the shaft 54 rotates when the moving block BL and the undersheave 52 move.

On the other hand, the above-described switching member (SM) may be configured to include, for example, the conductor 55 and the Hall element 56 as shown enlarged. The conductor 55 is made of a magnet or a conductive metal material. The conductor 55 is preferably provided integrally on the shaft 54 as shown in enlargement, and more preferably provided on the shaft 54b of the shaft 54 fitted to the bearing BR. As shown in the enlarged view, the hall element 56 may be built in the case CS and installed close to the outer side of the conductor 55 to be spaced apart from the conductor 55.

Hall element 56, when the current is generated by the conductor 55 is rotated with the shaft 54b of the shaft 54, this is not shown power supply of the above-described winding machine 40 or rolling mill 20 It is applied to the switch to operate the power supply switch. At this time, the power supply switch cuts off the supply power of the winder 40 or the rolling mill 20. Therefore, the winding machine 40 and the rolling mill 20 are emergency stopped. That is, the hall element 56 is a member for applying the switching signal to the power supply switch to emergency stop the winding machine 40 or the rolling mill 20. Since the operation of the conductor 55 and the hall element 56 is easily understood by those skilled in the art, a detailed description thereof will be omitted.

As a result, the switching member SM emergency stops the winder 40 or the rolling mill 20 when the metal wire 2 is excessively tensioned and the under sheave 52 moves together with the moving block BL. At this time, the switching member SM detects the rotation of the shaft 54 in a non-contact manner to emergency stop the winder 40 or the rolling mill 20. Therefore, the tensioned metal wire 2 is not pulled while the winding machine 40 or the rolling mill 20 stops driving, thus preventing further tension and cutting.

On the other hand, unlike the above-described switching member (SM) may be configured as a limit switch (LS) for the Hall element 56 in contact with the conductor (55). That is, the switching member SM may be configured to be operated by the limit switch LS instead of the hall element 56. At this time, it is obvious that the conductor 55 should be formed in a length that can contact the limit switch LS. In the switching member SM, the conductor 55 operates the limit switch LS when the shaft 54 rotates to apply a stop switching signal to the power supply switch. Therefore, the winding machine 40 and the rolling mill 20 are controlled by the switching member SM. Of course, the limit switch LS applies a driving switching signal to the power supply switch when the conductor 55 is reversely rotated by the shaft 54.

Unlike the foregoing, the switching member SM may be configured as a conventional optical sensor not shown in the hall element 56. That is, the switching member SM may be configured to be operated by an optical sensor instead of the hall element 56. The optical sensor is composed of a light emitting unit and a light receiving unit to detect the rotation of the shaft 54 through a laser that is received after being reflected from the conductor 55. At this time, it is preferable that the conductor 55 paints the white paint on the surface so that reflection is easy, and the shaft 54b of the shaft 54 preferably paints the black paint. Thus, the switching member SM operates in a non-contact manner. As such, the switching member SM operating as the optical sensor is easily understood by those skilled in the art, and thus its detailed description is omitted.

Unlike the above, the switching member SM is not shown in the conventional gyro sensor, which is not shown in the conversion of the rotation angle to time to calculate the rotation angle, or embedded in the video to detect the rotation angle of the jog shuttle or embedded in the mobile phone It can also be configured as a conventional motion sensor for detecting the angle of. That is, the switching member SM may be configured to be operated by a gyro sensor or a motion sensor instead of the conductor 55 and the hall element 56. The gyro sensor or the motion sensor senses that the shaft 54b of the shaft 54 is rotated and applies a switching signal to the power supply switch. Therefore, the power supply switch immediately cuts off the power when the switching signal is applied from the switching member SM. Since such a gyro sensor or a motion sensor can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

Unlike the foregoing, the switching member SM may be configured of a conventional solenoid (not shown) in which a coil is wound. At this time, the conductor 55 should be composed of a magnet. The switching member SM generates a current during rotation of the shaft 54 and applies it to the power supply switch. Therefore, the power supply switch immediately cuts off the power when the power is applied from the switching member SM. Since the solenoid switching member (SM) is a technology that can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

On the other hand, the power circuit breaker described above may be configured as a proximity sensor 57 that is installed in close proximity to the under-sheave 52 as shown instead of the switching member (SM). Proximity sensor 57 is composed of at least one sensor body (57a) as shown, consisting of an ultrasonic sensor, a photo sensor or a hall sensor, and is installed close to the under-sheave 52 by a member such as a pole (57b). .

Proximity sensor 57 may be composed of a lower sensor body (57a) facing the under-sheave 52 and the upper sensor body (57a) located on the upper portion of the under-sheave (52). The proximity sensor 57 detects that the metal wire 2 is tense through the lower sensor body 57a when the under sheave 52 rises together with the moving block BL. That is, the proximity sensor 57 detects that the lower sensor body 57a detects the detachment of the under sheave 52 so that the metal wire 2 is tense. In this case, the proximity sensor 57 may apply a stop signal directly to the power supply switch. Alternatively, the proximity sensor 57 may apply a stop signal when the under sheave 52 is adjacent to the upper sensor body 57a. Therefore, the proximity sensor 57 can prevent the metal wire 2 from being cut. Since the proximity sensor 57 can omit the aforementioned shaft 54 or the switching member SM, the proximity sensor 57 can be easily manufactured.

Referring to FIG. 8, the winding machine includes, for example, an insertion shaft 41 and a rotation motor 43, fasteners and horizontal winding means as shown.

Insertion shaft 41 is horizontally installed on the upper portion of the driver 45 as shown, is inserted into the hollow of the bobbin (BB). The insertion shaft 41 is integrally fixed with the bobbin BB by a fastener.

This fastener is, for example, is provided on one side of the insertion shaft 41 and the cone-shaped one side cone 42a fitted to one side of the hollow formed in the bobbin BB; The other side cone (42b) of the conical shape is screwed to the other side of the insertion shaft 41 in the opposite state to the one side cone (42a) fitted to the other hollow side formed in the bobbin (BB); At this time, one side of the cone (42a) is configured to be detachable from the insertion shaft 41 may be fixed by screwing on one side of the insertion shaft (41). And, the other side cone 13 is formed in the center through the screw hole can be fixed to the other side of the insertion shaft 41 by screwing. The other side cone 13 is screwed to adjust the separation distance with the one side cone (11). Therefore, the insertion shaft 41 can fix the bobbin BB of various lengths.

The rotary motor 43 is directly connected to the insertion shaft 41 or connected to the insertion shaft 41 by a pulley or chain as shown. The rotary motor 43 rotates the insertion shaft 41 to wind the metal material into the bobbin BB. That is, the bobbin BB is wound by the insertion shaft 41 to wind the metal wire 2.

The horizontal winding means is an element for winding the metal wire 2 wound on the bobbin BB by the rotary motor 43 in the bobbin BB in a horizontal state. This horizontal winding means may comprise a shuttle 44 and a driver 45.

Shuttle 44 may be formed in a block shape as shown. Shuttle 44 is a rotary motor 43 and the insertion shaft 41 is installed as shown in the reciprocating horizontally. At this time, the shuttle 44 moves along the guide bar (GB) horizontally installed as shown. Therefore, the bobbin BB winds the metal wire 2 in a horizontal state by reciprocating the shuttle 44.

The driver 45 reciprocates the shuttle 44 by sliding the shuttle 44 in the horizontal direction. The driver 45 may include, for example, a lead screw 45a, a screw motor 45b, and a motor switch 45c, as shown.

As shown in the drawing, the lead screw 45a is formed in a pair, and both ends thereof are rotatably fixed to the plate-shaped frame F spaced apart from each other. Lead screw 45a is pivotally rotated by screwing in a horizontal state on one side of the shuttle 44 as shown. The lead screw 45a may be screwed to the shuttle 44 through a female screw 44a provided in the same body as the shuttle 44 as shown. Accordingly, the lead screw 45a moves the shuttle 44 forward or backward while pivoting in the forward or reverse rotation.

The screw motor 45b is connected to the lead screw 45a as shown to rotate the lead screw 45a forward or reverse rotation. The screw motor 45b may be directly connected to the lead screw 45a as shown, or may be connected to the screw motor 45b through a pulley or a gear not shown.

The motor switch 45c is provided at both sides of the lead screw 45a as shown. The motor switch 45c senses the movement of the shuttle 44 moving along the lead screw 45a and applies a forward rotation signal or a reverse rotation signal to the screw motor 45b. That is, the motor switch 45c automatically rotates the screw motor 45b forward or reverse according to the movement of the shuttle 44. The motor switch 45c may be configured as a non-contact Hall sensor, a photo sensor, or a contact limit switch.

In conclusion, the driver 45 automatically reciprocates the shuttle 44 to horizontally move the bobbin BB. Therefore, the bobbin BB can wind the metal wire 2 while moving in the horizontal state. That is, the bobbin BB can be evenly wound around the metal wire 2 without any deflection.

Here, the above-described driver 45 may be composed of a hydraulic or pneumatic cylinder not shown instead of the lead screw 45a and the screw motor 45b. This cylinder has a rod connected to the shuttle 44. Thus, the cylinder moves the shuttle 44 horizontally through the stretching rod. Of course, the cylinder automatically reciprocates the shuttle 44 by the above-described motor switch 45c. That is, the driver 45 should be provided with the above-mentioned motor switch 45c even if it is comprised by the cylinder.

On the other hand, the winding machine 40 may be provided with a counter for detecting the rotation of the insertion shaft 41 and counting the number of windings of the metal wire (2) wound on the bobbin (BB). Therefore, the winder 40 can wind the metal wire 2 as many times as desired by the counter.

The counter is provided on the insertion shaft 41 as shown, for example, and has a projection 47a in the form of a projection made of a magnet or a conductive metal material; It may be configured to include; a hole element (47b) is installed close to the conductor (47a) for detecting the rotation of the conductor (47a). This conductor 47a is rotated together with the insertion shaft 41. The hall element 47b counts the number of revolutions through the current generated intermittently during the rotation of the conductor 47a. Therefore, the winder 40 may check the number of turns of the metal wire 2 by sensing the number of rotations of the insertion shaft 41. Of course, the hall element 47b applies a current to a control module (not shown) to control the number of windings of the metal wire 2 through the control module. That is, the control module stops the driving of the winding machine 40 and the rolling mill 20 when the set number of turns after counting the number of turns of the metal wire 2 through the current of the hall element 47b.

Here, the above-described conductor 47a and the hall element 47b may be formed of a conventional photosensor or ultrasonic sensor, not shown. Since this configuration is easily understood by those skilled in the art, a detailed description thereof will be omitted.

On the other hand, the winding machine may further include a proximity sensor 49 as shown. The proximity sensor 49 is installed close to the bobbin BB as shown to sense the winding thickness of the metal wire 2 wound on the bobbin BB. The proximity sensor 49 may be configured as a conventional non-illustrated photosensor or ultrasonic sensor. Since the proximity sensor 49 is easily implemented by those skilled in the art, a detailed description thereof will be omitted.

Referring to FIG. 9, the horizontal winding means may include a reciprocating roller 71, a roller bar 73, a pinion gear 75, a pinion motor 77, and a motor switch 79.

The reciprocating roller 71 is disposed on one side of the bobbin BB to guide the metal wire 2 to the bobbin BB. That is, the reciprocating roller 71 is a roller wound around the bobbin BB while the tension of the metal wire 2 is maintained while idling at one side of the bobbin BB.

The roller bar 73 is coupled to the reciprocating roller 71 in a horizontal state, and moves together with the reciprocating roller 71 while sliding in the longitudinal direction. The roller bar 73 is coupled to the frame (FL) in a slidable state as shown, and the recreation gear 73a is formed in the longitudinal direction.

The pinion gear 75 meshes with the rack gear 73a formed on the roller bar 73, and moves the roller bar 73 while rotating by the pinion motor 77 to move the reciprocating roller 71 to the bobbin BB. Horizontally move relative to That is, the reciprocating roller 71 moves horizontally by the engagement structure of the recreation gear 73a and the pinion gear 75. As shown in FIG.

The pinion motor 77 is connected to the pinion gear 75 to rotate the pinion gear 75 forward or reverse. The pinion motor 77 may be directly connected to the pinion gear 75, or may be connected to the pinion gear 75 through a pulley or a gear not shown.

The motor switch 79 is disposed on both sides of the reciprocating roller 71 as shown in the figure, and detects the movement of the reciprocating roller 71 moving together with the roller bar 73 so that the pinion motor 77 rotates forward or reverse. Apply the rotation signal. That is, the motor switch 79 rotates the pinion gear 75 forward or reverse in response to the movement of the reciprocating roller 71 to reciprocate the reciprocating roller 71 to the width of the bobbin BB. The motor switch 79 may be configured as a non-contact Hall sensor, a photo sensor, or a contact limit switch.

In conclusion, the horizontal winding means may be configured such that the reciprocating roller 71 for guiding the metal wire 2 winds the metal wire 2 into the bobbin BB while reciprocating in a horizontal state, and thus the metal wire 2 is It is wound up uniformly without being deflected at any one of the bobbins BB.

Referring to the accompanying drawings, the operation of the line-shaped metal forming apparatus according to an embodiment of the present invention as described above are as follows.

Referring to Figure 1, in the line-shaped metal material forming apparatus according to an embodiment of the present invention, as the bobbin BB of the winder 40 is rotated to wind the metal wire 2, the drum 1 of the feeder 10 The metal wire 2 wound around is drawn out. That is, the metal wire 2 is pulled out from the drum 1 by the winding machine 40. This metal wire 2 is continuously drawn from the drum 1 to the winder 40 by the idle roller IR as shown.

The rolling mill 20 presses the drawn metal wire 2 to reduce the volume of the metal wire 2. Such a rolling mill 20 repeatedly reduces the volume of the metal wire 2 when it is composed of a plurality. Therefore, the rolling mill 20 supplies the narrowly formed metal wire 2 to the winding machine 40 through the atmosphere furnace 30.

The atmosphere furnace 30 surface-treats the metal wire 2 whose volume was reduced in the rolling mill 20 as shown. At this time, the atmosphere furnace 30 is a surface treatment of the metal wire (2) in the hydrogen gas atmosphere. Therefore, the metal wire 2 is surface-treated by the hydrogen atmosphere and supplied to the winder 40 in a state where discoloration is prevented.

On the other hand, the stopper ring 35a and the elastic member 35b prevent shrinkage of the lead-out pipes 31 and 33 which allow the metal wire 2 to penetrate the atmosphere furnace 30. That is, the draw-out pipes 31 and 33 are not deformed because the shrinkage is suppressed by the stopper ring 35a and the elastic member 35b during cold operation due to the end of the operation of the atmosphere furnace 30.

The rolling mill 20 guides the metal wire 2 to the atmosphere 30 through the cleaner 60, and supplies the metal wire 2 to the atmosphere furnace 30 with impurities removed. At this time, since the load of the weight 63 is transmitted to the face cloth 61, the cleaner 60 wipes the surface of the metal wire 2 in a state where the metal wire 2 is gripped by the face cloth 61. Thus, the cleaner 60 supplies the metal wire 2 to the atmosphere furnace 30 in a state where impurities are almost completely removed.

On the other hand, the brake 50 detects the tension state of the metal wire (2) withdrawn from the rolling mill 20 or supplied to the winder 40 as shown. The brake 50 is driven when the winding machine 40 and the rolling mill 20 when the metal wire 2 is excessively tensioned and the under sheave 52 rises together with a broken line as shown in an enlarged view. Emergency stop. Therefore, the thinly shaped metal wire 2 is no longer pulled, i.e., it is no longer wound on the winder 40 while no longer pulled out of the feeder 10, and thus cutting is prevented.

Referring to FIG. 2, when the length of the drum 1 is short, the feeder 10 rotates the handle 15a of the screw shaft 15 to move the other side cone 13 in one side of the cone 11. On the contrary, when the length of the drum 1 is long, the feeder 10 rotates the screw shaft 15 oppositely to separate the other side cone 13 from the one side cone 11. Thus, the feeder 10 can rotatably fix the drum 1 of various sizes.

On the other hand, when the rotational speed control means rotates faster than the rotational speed of the winding machine 40, the rotation speed control means adjusts the turnbuckle 14c to press the lever sheave 14a through the pressure rope 14b One side of the cone (11) to move the lever, causing the frictional force on the one side of the cone (11) and the drum (1) to slow down the rotational speed of the drum (1). On the contrary, the feeder 10 adjusts the turnbuckle 14c when the rotational speed of the drum 1 is slower than the rotational speed of the winder 40 to relax the pressurized rope 14b and the one-side cone 11. The frictional force between the drums 1 is reduced to increase the rotational speed of the drums 1. Therefore, the rotation speed control means can control the rotation speed of the drum 1 to a speed corresponding to the rotation speed of the winder 40.

Referring to FIG. 5, the rolling mill 20 presses the metal wires 2 through one side roller R1 and the other side roller R2 which rotate in a state facing each other as shown. When the rolling mill 20 rotates the handle 25a of the pivot screw 25, one side roller R1 may be brought into close contact with the other roller R2, or may be spaced farther apart. At this time, the pivot screw 25 raises and lowers the nut 27a fixed to the movable disk 27 so as to contact or space one roller R1 from the other roller R2. Of course, the one side roller (R1) is in close contact with or spaced apart from the other side roller (R2) as the shaft is fixed to the moving disk (27).

As shown in the figure, the pivot screw 25 is fixed in a rotated state as the elastic body 29 elastically supports the movable disk 27. That is, the pivot screw 25 is not loosened by the elastic force of the elastic body 29.

On the other hand, the metal wire 2 is accurately guided between one roller (R1) and the other roller (R2) by the front idle roller (IR) of the one side roller (R1) and the other side roller (R2) as shown.

Referring to FIG. 7, the brake unit 50 emergencyly stops driving of the winder 40 and the rolling mill 20 when the under sheave 52 moves as shown by a broken line. At this time, the brake 50 may emergency stop driving of the winding machine 40 and the rolling mill 20 by the sensor main body 57a of the proximity sensor 57, unlike the protrusion PT of the moving block BL. ) And the driving of the take-up 40 and the rolling mill 20 through the switching member (SM) operated by the shaft 54 can be emergency stop. Of course, the proximity sensor 57 and the switching member SM apply a stop signal to the power supply switches of the winder 40 and the rolling mill 20 to stop the driving of the winder 40 and the rolling mill 20.

Here, the above-described protrusion PT rotates the spiral rail 54a of the shaft 54 while moving together with the moving block BL. At this time, the shaft 54 is rotated by the spiral rail (54a) to operate the switching member (SM).

The switching member SM applies the current of the hall element 56 generated by the conductor 55 which rotates together with the shaft 54 to the power supply switch, not shown. Thus, the power supply switch stops supplying power to the winder 40 and the rolling mill 20.

Referring to FIG. 8, the winder 40 winds the metal wire 2 to the bobbin BB as the bobbin BB is rotated together with the insertion shaft 41 by the rotation motor 43 as shown. . The winder 40 evenly winds the metal wire 2 without deflection as the bobbin BB horizontally reciprocates by the shuttle 44.

The driver 45 reciprocates the shuttle 44 while rotating the lead screw 45a forward or reverse through the screw motor 45b. At this time, the driver 45 automatically reciprocates the shuttle 44 repeatedly by only the section set by the motor switch 45c. Therefore, the bobbin BB winds up the metal wire 2 while reciprocating only the distance set by the shuttle 44.

On the other hand, the winder 40 is fixed to the insertion shaft 41 of the bobbin (BB) of various lengths as the other side cone 42b is screwed to the insertion shaft 41 adjacent or spaced apart from one side of the cone 42a. Can be.

Referring to FIG. 9, the metal wire 2 is wound in a horizontal state on the bobbin BB while the reciprocating roller 71 moves by the pinion gear 75 and the pinion motor 77 together with the roller bar 73. At this time, the reciprocating roller 71 repeatedly reciprocates the section set by the motor switch 79, that is, the width of the bobbin BB. Therefore, the metal wire 2 is uniformly wound by the bobbin BB.

Line-type metal material forming apparatus according to an embodiment of the present invention as described above, because the metal wire (2) rolled in the rolling mill 20 is continuously surface-treated through the surface treatment machine without special processing of the rolled metal wire (2) immediately can do.

In addition, the bending deformation of the lead-out pipes 31 and 33 can be prevented, so that the metal wire 2 can be passed through the atmosphere furnace 30 in a straight line state.

In addition, since the other side cone 13 of the feeder 10 may be closer to or farther from the one side cone 11 through the screw shaft 15, the drum 1 of various lengths may be rotatably fixed, in particular one side Since the cone 11 and the other side cone 13 are formed in a conical shape, the fixed drum 1 can be smoothly rotated.

In addition, since the rotation speed of the drum 1 can be adjusted through the rotation speed control means, the drum 1 rotates faster than the winder 40 so that the metal wire 2 is tangled or later than the winder 40. Rotation of the metal wire 1 can be prevented.

Moreover, since the drum speed is adjusted through the adjusting member to support the drum, the speed of the drum can be adjusted easily and stably.

In addition, since the distance between the one roller (R1) and the other roller (R2) can be adjusted while moving the one side roller (R1) of the rolling mill 20 through the adjuster, the volume of the metal wire (2), that is, the thickness or thickness easily I can regulate it.

In particular, since the pivot screw 25 of the adjuster is finely rotated by the screw thread, the one side roller R1 is finely moved together with the moving disk 27, so that the moving distance of the one side roller R1 can be precisely adjusted. In addition, since the elastic body 29 elastically supports the pivot screw 25 through the movable disk 27, the pivot screw 25, which has been rotated, may be prevented from being rotated when the rollers R1 and R2 rotate.

In addition, when the rolling mill 20 is configured in plural, the metal wire 2 drawn out from the drum 1 may be gradually thinned while rolling stepwise, thereby improving the quality of the formed metal wire 2.

In addition, the surface treatment agent surface-treats the metal wires 2 through liquid or gaseous chemicals so that the metal wires 2 can be surface treated while preventing the metal wires 2 from being damaged. In the case of the furnace 30, the surface of the metal wire 2 can be surface treated with a gas atmosphere while the heat treatment of the metal wire 2 is performed. Therefore, the surface treatment of the metal wire 2 can be performed more reliably in a short time by the simultaneous heat treatment and gas reaction. Further, when the metal wire 2 is surface-treated with a hydrogen base, the passivation of the metal wire 2 proceeds smoothly, thereby preventing oxidation and discoloration of the metal wire 2.

In addition, the winding machine 40 winds the metal wire 2 to the bobbin BB while horizontally moving the bobbin BB through the shuttle 44 reciprocated by the driver 45, thereby deflecting winding of the metal wire 2. Since the bobbin BB is fixed to the insertion shaft 41 of the winder 40 by fasteners formed of one side cone 42a and the other side cone 42b in which the distance between each other is adjusted, and thus, various lengths. Not only can fix the bobbin BB to the winder 40, but also the driver 45 automatically reciprocates the shuttle 44 by the motor switch 45c only in a set section, thereby allowing the metal wire 2 to be bobbin ( BB) can be wound tightly.

On the contrary, since the reciprocating roller 71 guides the metal wire 2 to the bobbin BB while horizontally moving by the rotation of the pinion gear 75 together with the roller bar 73, the metal wire (without moving the bobbin BB) 2) can be uniformly wound on the bobbin BB, and the gear engagement structure of the recreation gear 73a and the pinion gear 75 enables accurate operation control of the reciprocating roller 71.

Furthermore, the metal wire 2 is wound around the winder 40 because the brake 50 senses excessive tension of the metal wire 2 to be molded to emergencyly stop the driving of the winder 40 and / or the rolling mill 20 through a power circuit breaker. Or cut by malfunction of the rolling mill 20, and in addition, when the power breaker is configured to operate when the under sheave 52 is moved, the excessive tension of the metal wire 2 can be mechanically confirmed. Furthermore, when the shaft 54 having the protrusion PT and the spiral rail 54a is configured to drive the switching member SM, the switching member SM can be mechanically operated, thereby preventing the operation of the switching member SM. Not only can it be semi-permanently realized, but also when the switching member SM is composed of the conductor 55 and the hall element 56, the switching member SM can be operated in a non-contact manner.

On the contrary, when the power circuit breaker is configured as the proximity sensor 57 for detecting the position of the undersheave 52, the power circuit breaker can be easily configured.

In addition, when a plurality of brakes 50 are configured, excessive tension of the metal wire 2 can be detected more accurately, and therefore, the metal wire 2 can be formed more stably.

Since the above-described embodiments are merely illustrative of the preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
