The present invention relates to an apparatus for producing a metal tape, for the purpose of providing an apparatus for increasing the width direction in manufacturing the metal tape with a metal round wire or a square wire.

Conventionally, in order to manufacture a metal tape, a device for press molding from a round wire or a square wire, a device having a thin plate inserted into a splitter, and a tape having a predetermined width is known. However, according to the former device, the diameter d of the hollow line and the tape The relationship between the width b and the thickness t has the following expression.

Therefore, in order to obtain a tape having a width of 20 mm and a thickness of 1 mm, a line having a diameter of 10 mm needs to be used. However, when stretched by such a device, the long edge of the tape is extremely poor (for example, wave length or cracking), and not only causes quality deterioration. Depending on the application, it may not withstand use.

In addition, the latter requires the installation of massive equipment to manufacture thin plates, not only to allow the price of metal tapes to rise, but also to make a magnificent product.

It has also been known that rolling deformation of a wire rod onto a tape by such a device tends to cause tearing or cracking of the edges of the tape.

This occurs because the difference between the maximum rolling load and the minimum rolling load in the cross-sectional direction of the tape width becomes large, and the surface is shrunk due to pulling during press molding, so that a small crack ( Hair cracks) are known to be largely cracked like a claw on a jigsaw.

However, the manufacturing apparatus of the present invention performs the forward and backward rotation of the processing member (for example, a roll) and inserts the processing line in the lateral direction of the pressing member, thereby shifting the pressure deformation of the wire rod almost in the width direction. It is an apparatus that solves the above-mentioned conventional problems by almost eliminating the difference between the maximum rolling load and the minimum rolling load in the long axis of the wire rod and the cross section at right angles.

According to the apparatus of the present invention, the guide port of the work piece is installed on the insertion line side of the set of electric pressing members and the guide port of the molded product is installed on the outlet side of the molded product at right angles to the insertion axis of the work line. It is a device that allows the pressurized part to be processed evenly by parallel reciprocating movement of the line to be processed according to the reciprocating movement in the forward / reverse direction of the electric pressure member.

Therefore, the wire to be processed is rolled in the direction perpendicular to its major axis so that there is no fear of cracking. In addition, by rolling in the direction parallel to the long axis of this product, the final product is rolled vertically and horizontally, which significantly improves the rolling performance of the tape and at the same time improves the breaking performance of the produced water. It is an apparatus which can obtain the outstanding quality which cannot be obtained from (other tape-like material made from hoop).

In addition, since the device for intermittently feeding the processing line is installed, the processing of the present invention is fully automatic and can be continuously processed under the same conditions. Therefore, it is a device capable of forming a high quality and uniform metal tape continuously and elongately. . Next, the principle of the production apparatus of the present invention will be described with reference to FIGS.

One side of one set of rolls 1 and 2 is formed in a conical shape, and the gap is wider as it approaches the end face of the roll. (Figure 1).

In the above, the circular line 4 is inserted as shown by the arrow 3 during the first middle, and the rolls 1 and 2 are reciprocated in the forward and reverse directions by a predetermined rotational angle as shown by the arrow 5 and 6 during the second middle arrow. It is configured to move forward as shown in arrow 8 while moving in parallel as shown in arrow 3 in FIG.

In this way, the ring line is processed flat in order from the tip, and finally, it becomes tape 9 and is installed to exit as shown by arrow 10. In the former, the insertion of ring 4 should be made when it is not rolled (eg when the ring is on the a side or b side of the second road), so these devices are intermittently rotated so that the forward and reverse rotations of rolls 1 and 2 It must be synchronized with the main body, and moreover, it should be inserted as soon as possible. Therefore, as one example is shown in the embodiment, it is preferable to store the pressing force in the forward direction of the ring line and to adopt an apparatus which can be inserted immediately when the pressing force is reduced.

Next, the embodiment of the present invention will be described with reference to FIGS. 4 to 15.

As shown in Fig. 4, the riveting portions of the side fan-shaped pressing members 11 and 12 are temporarily installed by the ground sides 13 and 14, and one end of the connecting part 15 and 16 is connected to the sides of the electric pressing members 11 and 12 by pins. The other end of the connection 15 and 16 is connected to the drive shafts 30 and 31 by eccentric wheels 17 and 18. Super-economics 19 and 20 are embedded in the pressing surfaces of the electric pressing members 11 and 12, and each pressing member is tapered to form one side thereof as shown in FIG.

As shown in FIG. 22, when the driving side 30 and 31 are rotated, the connecting members 15 and 16 reciprocate as shown by arrows 23 and 42, and the pressure members 11 and 12 perform reciprocating fan-shaped motion as shown by arrows 25 and 26.

Therefore, when the ring line 4 is inserted as shown by the arrow 27 in the fourth way, the ring line 4 is processed on the tape at the tip side thereof, and the tape 9 is pulled out as shown by the arrow marks 28.

In the former, when the line 4 is hooked on the pressure members 11 and 12 as shown by arrow 29 in the seventh way, the ring 4 is pressurized but the corner part 4 of the ring 4 is the front corner and the corner b is the rear corner. The rolling weights in are almost the same, and the edges are not concerned when cracks occur.

The apparatus shown in FIG. 4 thru | or FIG. 7 becomes an implementation apparatus like FIG. 8 thru | or 11, for example.

That is, the eccentric wheels 17 and 18 are connected to the driving side 30 and 31, and the gears 32 and 33 are fixed to the driving sides 30 and 31, and the gears 32 and 33 are different from the gears 36 and 37 fixed to one end of the intermediate shafts 34 and 35. The gears 38 and 39 are engaged with the gears 42 and 43 fixed to one end of the motors 40 and 41 of the motors 45 and 46, and the timing belt 44 is attached to the other end of the shafts 40 and 41 of the motor. It is comprised so that rotation of both sides 40 and 41 may be completely synchronized.

Motor 45 and 46 and drive shafts 30 and 31 are moved through the respective gear groups as before. When starting motors 45 and 46, the pressure members 11 and 12 are driven as described in FIG. do. On one side of the above-mentioned device (opposite axis and return line to the motor), guides 48 with guide holes 47 as horizontal guides (4 in the case of arrow 12) can be installed horizontally. Springs 50 and 51 are installed in tension in the direction. That is, the springs 50 and 51 respectively secure one end to the housing 52 and the other end to the protrusion 53 and 53a. The rack 55 is installed at one side of the guide section 48 (left side of FIG. On 56 is bitten from each other, and pinion 56 is fixed to one end of pinion axis 57.

The pinion shaft 57 is horizontally installed in the housing, the other end of which is fixed to the other side (motor side) of the housing 52, and the pinion 58 is fixed, and the pinion 58 is interlocked with the rack 60 of the guide bar 59 on the tape outlet side. . Guide grooves 61 of the same width as the tape 9 are provided at the center of the guide section 59, and are supported in tension in the left and right directions by springs 62 and 63, which are installed between the projections 54, 54a and the housing, and slide horizontally. It is installed as possible. Next, the upper end of the rod 64 is connected to the outer wall side of the eccentric wheel 18 by the flow port 67, and the lower end of the rod 64 is perpendicular to the drive shaft 31, which is electric. Connected to the flow port 68, the electric fan gear 66 is meshed with the rack 69 of the interlock 70 installed in the housing parallel to the drive shaft 31 described above.

Next, the intermittent insertion apparatus will be described with reference to FIGS. 14 to 21. The interlocking rod 70 described above is installed as an input of a device for feeding the rod 4, and is connected to the input 72 of the intermittent insertion device via the connection 71 and the connectors 73 and 74.

In the input 72, racks 75 and 76 are installed on the upper and lower walls, and the pinions 77 and 78 are engaged with each other, so that the gears 81 and 82 staked on the pinion shafts 79 and 80 mesh with the gear 88 of the intermediate shaft 83. have. The gears 81 and 82 described above are constituted by one-way clutches which conduct rotational force only when the flywheels 84 and 85 rotate in the directions of 86 and 87 at the arrows of the 16th degree, respectively.

It is meshed with the gear 92 of the pinion shaft 91 installed in the housing 90 in parallel and horizontally parallel to the intermediate shaft 83 described above. .

Therefore, when the pair of gears 89 and 92 is exchanged, it is comprised so that the amount sent by a pinch roll can be regulated. The pinion 93 is fixed to one end of the pinion shaft 91, and the pinion 93 meshes the pinch with the gear 95, which is regrettable on the shaft 94. The three protrusions 96 are radially installed at equal intervals on each side of the gear 95. In the pinch, pin 97 in parallel with the axis 94 is implanted. One pinch is secured to the boss 98 on the shaft 94. On one side of the boss 98, the projected protrusion 96 and the corresponding number of protrusions 99 are radially spaced apart at equal intervals. Spring 97 is installed in each group of pins with 97 and pin 100 corresponding to each group. (There are 6 springs for 3 pins.)

That is, when one end of the spring 101 is fixed to the pin 97 and the other end is fixed to the pin 100, and the gear 95 rotates by a predetermined angle, the boss 98 is connected through the spring 101 so as to rotate the same angle.

Therefore, when the gear 95 rotates and the boss 98 does not rotate, the rotation force is output to the spring 101.

The interlocking gears 102 and 102a and the pinch rolls 103 are fixed to the pinch roll shaft 94, and the interlocking gears 102 and 102a are engaged with the gears 104 and 104a of the pinch roll shaft 115 installed in the housing 119 in parallel with the pinch roll shaft 94. The pinch roll 105, which is co-operated with the pinch roll 103, is also fixed to the pinch roll shaft 115.

On the way (FIG. 6) 106, 107, 108 and 109 are guide rolls between inputs. The operation thereof will be described with reference to FIGS. 16 to 21. 1 rotation of the drive shaft 31 shown in FIG. 11 (the rod 64 moves up and down as 119 and 111 at the time of the arrow and is one reciprocating). Since the fan gear 66 is one reciprocating rotation, 70 is interlocked between the interlocks through the rack 69. When it slides, 72 reciprocates between the inputs connected to it. For example, if the input 72 moves in the direction of arrow 14 during the 16th direction, the gear rotates in the direction of 87 when the arrow 16 in the 16th direction by the engagement of the rack 76 and the gear 78 and pushes the driving force through the flywheel 85. It transmits to the on-axis 80 and transmits the driving force to the intermediate shaft 83 by rotating the gear 88 of the intermediate shaft 83 via the gear 82 of the pinion shaft 80, and the gear 92 of the pinion shaft 91 which rotates and engages the gear 89 of the intermediate shaft 83. Rotate pinion axis 91 in the direction of arrow 118 by using.

When the pinion shaft 92 rotates, the pinion 93 rotates in the same direction and transmits it to the gear 95. The rotation of the gear 95 is transmitted from the pin 100, the pin 99 and the boss 91 via the protrusion 96, pin 97 and spring 101 to the boss 98. The pinch roll shaft 94 rotates by the pinch roll 103. In this case, the rotation of the pinch roll shaft 94 is transmitted to the gears 104 and 104a by the gears 102 and 102a so as to rotate the pinch roll shaft 115 so that the pinch rolls 103 and 105 move the ring line jointly.

In electrical, when the input 72 moves in the direction of 114 at the arrow, the gear 77 rotates in the direction of 120 at the arrow 75, but the rotation is not transmitted to the pinion shaft 79 by the flywheel 84, so that the gear 81 and the gear 88 There is no fear of disturbing the interlocking.

If one of the inputs moves in the direction of arrow 16 in arrow 16 during double acting, the rotation between rack 75 and pinion 77 (in the direction of arrow 86 in the middle of arrow in the same direction) passes through pinion 84 Intervene with gear 77 transmitted to shaft 79 and rotate gear 88 of intermediate shaft 83 (117 during the same arrow) to rotate gear 92 of pinion shaft 91 in the direction of arrow 118 through gear 89. .

The pinch rolls 103 and 105 are rotated in the same manner as described above (when input from the pinion shaft 90). In the present invention, the insertion of the round wire should be made when the round wire does not enter the pressing member (other than press forming).

And the transfer of the ring line should be done immediately and surely, but in the device of the present invention, the output of the spring 101 is always applied by the pinch roll, so the force applied to the ring line is released and at the same time the pinch roll is released by the elasticity of the spring 101. It rotates rapidly and it is comprised so that a ring line may be fed. In the description of the foregoing embodiment, although the round wire is used as the material to be processed, there are not only the round wire but there are square wires, elliptical wires, flat wires, etc., and the groove shape of the pinch roll is not determined in correspondence with the cross-sectional shape of the wire.

In the above embodiment, the gear group is used as the interlocking device between the motor and the drive shaft, but the specific structure thereof is not limited to the embodiment. In addition, by using the rotation of the eccentric wheel and moving between inputs through rod, fan gear, rack and connection, etc., it was used as the driving force of the pinch roll, but this gives the pinch roll rotational force in response to the movement of the pressure member of the rolling device shaft. It is to be noted that the gist of the present invention is not limited to the configuration of the interlocking system by the electric angle members.

Next, the Example of this invention is described. The summoning wire (5.5.2mm in diameter, 105kg / mm SK-5 in tensile strength, microfiber structure was formed by heat treatment) with a diameter of 5.5mm was set at an insertion speed of 10mm each time. The reduction rate was about 16%. This indicates that only about 16% of the material flowed in the roll axis direction (the direction of the major axis of the material).

Thus, the tensile strength after passage was 14 kg / mm. The finished tape was rolled again by 45% in the 90-degree direction (conventional rolling method) to obtain a thickness of 0.55 mm. The tensile strength was 166 kg / mm, and the center portion in the cross section perpendicular to the long axis of the tape was obtained. There was no crack on both sides. In addition, the acceleration degree in the case of press-molding a round-line diameter (5.5 mm) by 20 mm in width to the tape of thickness 1 mm was 10 mm per minute.

The taper angle of the roll in electricity is 1 degree. That is, according to the method of the present invention, the work piece is sequentially inserted from the end thereof by inserting the work line into one set of the electromotive force members in a direction parallel to the power shaft and rotating the electric motor force member forward and backward by a predetermined rotation angle. Since it is press-molded onto tape, it is easily rolled in the width direction regardless of ring or line, and the elongation in the length direction is as small as possible, and there is no fear of cracks or other irregular edges on the length of the product tape. It is effective to manufacture continuously. Since the work line is intermittently inserted when there is no pressing force, there is no risk of trouble when inserting, and moreover, there is an effect of obtaining a homogeneous product by inserting exactly as much as a predetermined stroke.

In addition, according to the device of the present invention, the support shafts of a set of electric pressing members are installed in parallel to each other, and the processing surfaces thereof are opposed to each other, and the guide and the guides of the blank line are moved in synchronization with each other. The tape can be swung in a fast position without being subjected to excessive external force and facilitates processing.

In addition, since the intermittent insertion device of the work line is synchronized with the transmission of the electric pressing member, it is a device that can be inserted reasonably and quickly by applying an insertion force just before the pressing force of the work line is released.
