Description

Cutting apparatus for drawing machine {Cutting apparatus for drawing machine}

The present invention relates to a cutting device for a drawing machine, and more particularly, by realizing automatic or semi-automated cutting of a drawing material to a set length, compared to a manual process of manually measuring and cutting the length of the drawn material, cutting the drawn material. It guarantees length accuracy and marketability of cutting surfaces, reduces costs by excluding unnecessary manpower, improves market satisfaction by guaranteeing productivity and shortening delivery times, and eliminates various risk factors in the field. It relates to a cutting device for a drawing machine that can significantly improve the environment.

When manufacturing semi-finished products such as metal, especially copper busbars, non-ferrous metal billets, tubes, and round bars, a drawing device is required.

A conventional drawing device injects molten steel manufactured in a continuous casting process or electric furnace, refining furnace, etc. into a ladle turret, connects a long nozzle to the ladle, injects the molten steel into a tundish, and removes inclusions contained in the molten steel injected into the tundish. When the levitation separation is performed, the molten steel is supplied to the mold through the immersion nozzle, and the drawing material is drawn into a certain shape through a cooling process.

At this time, it is common that the continuously drawn drawn member is cut into a predetermined length in accordance with the purpose in a drawn member cutting line, or is rolled in a roll form and transferred to a subsequent process.

On the other hand, in the conventional drawing material cutting line, the operator manually measures the length of the drawn drawing material by hand, marks the cutting position, and then directly cuts the cutting position using a tool such as a hand grinder. The precision of the length was poor, and the cutting was not finished neatly, which negatively affected productivity as well as product quality.

In addition, there is a problem in that safety accidents frequently occur because workers are constantly exposed to dangerous situations due to drawing materials drawn at high temperatures.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a cutting device for a drawing machine according to the present invention will be described.

The cutting device for a drawing machine according to the present embodiment is installed adjacent to a drawing machine (D), continuously cuts the drawing material (M) drawn by the drawing machine (D) to a set length, and stacks the cut drawing material (M) in multiple stages. can make it

To this end, the cutting device for a drawing machine according to the present invention, as shown in FIGS. 1 to 3, largely includes a guide unit (1), a brake unit (2), a cutting unit (3) and a stacking unit (4). can be defined as

First, the guide unit 1 receives the drawing material (M) drawn from the drawing machine (D) and guides it backward, guides the cut drawing material (M) in the right direction and discharges it toward the stacking unit (4). can do.

That is, the guide unit 1 has a structure that allows the drawing member M to be transported in at least two different directions.

More specifically, the guide unit 1 includes a plurality of support rollers 10 supporting the lower portion of the drawing member M being guided backward, and a lifting unit 20 for lifting the plurality of support rollers 10 up and down. and a discharging unit 30 discharging the drawing member M to the right side when the drawing member M is seated as the plurality of support rollers 10 descend.

Considering the shape of the drawing member M drawn long in the front-back direction, a plurality of support rollers 10 are arranged in a row along the front-back direction to support the drawing member M in a balanced manner.

At this time, the support roller 10 can be moved up and down by an elevating unit 20 to be described later while supporting the drawing member M. When the support roller 10 is located at the top dead center, the support roller 10 Is formed higher than the conveyor member 100 of the discharge unit 30 to be described later, so that the drawing member M can be spaced upward from the conveyor member 100, and the support roller 10 moves to the bottom dead center. Then, the support roller 10 is formed to be lower in height than the upper surface of the conveyor member 100, so that the drawing member M supported by the support roller 10 is spaced apart from the support roller 10 and then moved to the conveyor member 100. structure to be transmitted.

Thus, the drawing material M may be discharged toward the stacking unit 4 along the discharge direction of the discharge unit 30 .

The elevating unit 20 synchronously rotates (rotates) the plurality of support rollers 10 at a predetermined angle while supporting the plurality of support rollers 10 so that the support rollers 10 can move up and down.

More specifically, as shown in FIGS. 4 and 5 , the elevating unit 20 includes a plurality of first rotational shafts 21 installed in parallel with the support roller 10 and each of the plurality of support rollers 10 . A plurality of connecting brackets 23 for connecting and coupling to each of the first rotational shafts 21 at a predetermined distance from each other, and are disposed across the lower part of the plurality of first rotational shafts 21 in the front-back direction, and at the lower end, a connecting table 25 ) is provided, a plurality of interlocking links 26 connecting the plurality of first rotational shafts 21 and the interlocking frame 24, and installed at the bottom of the interlocking frame 24, and the connecting rod 25 ) and a first actuator 27 for reciprocating the interlocking frame 24 by coupling with it.

First, both ends of the first rotational shaft 21 may be rotatably installed in place on a lifting frame (not shown) via fixed bearings 22 .

The connection brackets 23 form a pair of two sets to connect one support roller 10 to one first rotational shaft 21.

At this time, the lower end of the connection bracket 23 is fixedly coupled to the first rotation shaft 21 and the other end may be rotatably coupled to the support roller 10 .

Accordingly, when the first rotational shaft 21 rotates at a predetermined angle, the support roller 10 may be rotated along the rotational direction of the first rotational shaft 21 .

The interlocking frame 24 is made of a frame-shaped member elongated in the front-rear direction, and here, each interlocking link 26 can be connected in place. At this time, the upper end of the interlocking link 26 is fixedly coupled to the first rotation shaft 21, and the lower end may be rotatably connected to the interlocking frame 24.

The actuator described in the present invention may be exemplified by a known electronic pneumatic cylinder, and at this time, the cylinder body of the first actuator 27 is rotatably connected and installed on a fixed frame without separate reference numerals, and the rod The end may be rotatably connected and installed to the connecting rod 25.

According to this structure, when the interlocking frame 24 reciprocates by the operation of the first actuator 27, each interlocking link 26 synchronously rotates each of the first rotational shafts 21 accordingly, and accordingly, a plurality of The two support rollers 10 may be rotated with the first rotational shaft 21 as a reference for rotation.

That is, when the first actuator 27 is extended according to the control signal, the linear motion of the first actuator 27 is converted into the rotational motion of the first rotational shaft 21 by the interlocking frame 24 and the interlocking link 26 By rotating the first rotary shaft 21 counterclockwise, the plurality of support rollers 10 can move to the top dead center in conjunction with each other, and conversely, when the first actuator 27 is compressed, the first rotary shaft 21 As this is rotated clockwise, the plurality of support rollers 10 may move to the bottom dead center in conjunction with each other.

As described above, when the support roller 10 moves to the bottom dead center, the drawing member M supported by the support roller 10 is also rotated downward to be seated in the discharge unit 30 .

The discharge unit 30 moves the drawing material M delivered from the support roller 10 to the right and discharges it to the stacking unit 4.

The discharge unit 30 in this embodiment may be made of a conventional conveyor structure, and may be installed between adjacent support rollers 10 to support and move the drawing member M in a balanced manner.

Next, the brake unit 2 is installed to reciprocate the upper part of the guide unit 1 in the forward and backward directions, and stops the drawing member M being guided backward at the set position before cutting the drawing member M plays a stabilizing role. That is, the length of the drawing member M to be cut can be adjusted by adjusting the position of the brake unit 2 forward and backward.

At this time, the brake unit 2 can stop and fix the drawing material M on the guide unit 1 by blocking the rear end of the drawing material M, ) can be cut.

More specifically, as shown in FIGS. 2 and 6 , the brake unit 2 is connected to the screw shaft 40 extending in the front-back direction on the left side of the guide unit 1 and the screw shaft 40. body 50, which is formed on the body 50 and is provided to be reciprocating in the forward and backward directions along the screw shaft 40, and a stopper 60 formed on the body 50 and supported by contact with the rear end of the drawing member M, and the stopper 60 It may be exemplified as including a signal generating unit 70 that is formed at a predetermined distance forward from ) and generates a deceleration signal that causes the drawing speed of the drawing machine D to be reduced when the drawing material M is in contact.

First, the fuselage 50 supports the stopper 60 and the signal generating unit 70, and can be positioned forward and backward by rotating the screw shaft 40. At this time, the body 50 is coupled with an LM guide structure, an encoder for measuring the amount of movement, etc., and has a structure capable of precisely measuring or controlling movement coordinates so that the body 50 can be moved and controlled to a desired position.

When the body 50 is fixed in position, the stopper 60 and the signal generator 70 may also be fixed in position, and the drawing member M guided by the guide unit 1 uses the signal generator 70 fixed in position. After passing through, it can be stopped and fixed by the stopper 60.

On the other hand, the cutting unit 3 is fixedly installed at the front end of the guide unit 1 and serves to cut the drawing material M. At this time, the length of the drawing material M to be cut is determined by the stopper 60 and the cutting It can be adjusted by the distance between the units (3).

That is, by controlling the relative movement of the body 50 forward or backward with respect to the position-fixed cutting unit 3, the length of the drawing material M to be cut can be adjusted to be longer or shorter, and furthermore, the drawing material ( Even without measuring the length of M) by hand, if the body 50 is moved and fixed at a desired position, the drawing member M is stopped and fixed at an appropriate position and the drawing member M can be cut to the desired length. is equipped

Adjustment of the position of the body 50 can be controlled wirelessly by a separate control means, and when the operator inputs a numerical value into the control means, the control means links the screw shaft 40, the LM guide structure, the encoder, etc. to control the fuselage ( 50) can be controlled to move to a position corresponding to the numerical value input by the operator.

Since such a specific structure for precise position control of the body 50 follows a typical LM guide structure, a detailed description thereof will be omitted.

The signal generator 70 is rotatably coupled to the front of the body 50 and is coupled between the circuit breaker 71 to which the drawing material M is in contact, and is coupled between the body 50 and the circuit breaker 71 and the drawing material M It can be exemplified as including a second actuator 72 for rotating the circuit breaker 71 rotated by ) to its original position and a rotation detection sensor (not shown) for generating a deceleration signal by detecting rotation of the circuit breaker 71 there is.

As shown in FIG. 6A, the drawn member M may be in line contact with the circuit breaker 71 placed in front of the stopper 60 before being supported in contact with the stopper 60, as shown in FIG. 6B. Likewise, the moment the drawing material M comes into contact with the circuit breaker 71, the circuit breaker 71 rotates in the direction of the body 50, so that the drawing material M does not interfere with the drawing direction.

When the circuit breaker 71 is rotated by the drawing member M, the rotation detection sensor detects this, generates a deceleration signal, and sends it to the drawing machine D.

Since the rotation detection sensor, which is not separately shown, can be implemented in various ways along the line capable of detecting the rotation of the circuit breaker 71, the installation location, structure, and the like are not specifically limited.

When the deceleration signal is sent to the drawing machine (D), the drawing machine (D) decelerates and controls the drawing speed of the drawing material (M) to prevent the drawing material (M) from colliding strongly with the stopper (60) Safety structure make up

On the other hand, when the drawing material M is cut and discharged toward the stacking unit 4, the circuit breaker 71, which has been rotated toward the body 50, is rotated by the second actuator 72 as shown in FIG. It can be set in situ.

Next, the stacking unit 4 serves to stack the cut drawing material M when it is guided to the right side by the guide unit 1 and discharged.

The stacking unit 4 is disposed on the right side of the guide unit 1 to receive the cut drawing materials M and stack them in multiple stages. In particular, the drawing materials M continuously discharged from the guide unit 1 side It has a structure that allows stacking in multiple stages up and down.

To this end, the stacking unit 4 is illustrated as including a shelf member 80 on which the drawing material M is stacked and a third actuator 90 that lifts the shelf member 80 in the vertical direction, thereby Accordingly, the shelf member 80 can be appropriately moved up and down.

Hereinafter, with reference to the accompanying drawings, the operation of the cutting device for a drawing machine according to the present invention will be described by taking a simple driving process of the cutting device for a drawing machine as an example.

First, the operator sets the guide unit 1 so that the support roller 10 is located at the top dead center, and the brake unit 2 so that the body 50 is positioned at an appropriate position in consideration of the length of the drawing member M to be cut. When drawing of the drawing machine D is started after setting , the drawing material M is guided backward along the support roller 10 by the drawing pressure of the drawing machine D.

When the drawing member M, which has been guided backward, contacts the circuit breaker 71, the signal generating unit 70 generates a deceleration signal and sends it to the drawing machine D by the occurrence of the contact. At this time, the drawing machine D reduces the drawing speed of the drawing member M by momentarily lowering the drawing pressure of the drawing member M based on the deceleration signal.

When the drawing member M moves further backward and contacts the stopper 60, the backward movement of the drawing member M is stopped, and at the same time, the cutting unit 3 operates to cut a part of the front end of the drawing member M. Cut it.

Thus, the drawing member M is cut to a length corresponding to the distance between the stopper 60 and the cutting unit 3.

When the cutting of the drawing member M is completed, the support roller 10 is rotated to the bottom dead center by the lifting part 20, and accordingly, as shown in FIG. 5, the drawing member supported by the support roller 10 ( M) is delivered to the discharge unit 30 and is seated and supported on the discharge unit 30 .

In this state, the discharge unit 30 discharges the cut drawing material M to the right and places it on the shelf member 80.

When the discharge of the drawing material M is completed by the discharge unit 30, the support roller 10 and the circuit breaker 71 are restored to their original positions, and this process is repeatedly performed to continuously cut the drawing material M. process can be performed.

At this time, by appropriately adjusting the vertical height of the shelf member 80, the drawing materials M continuously discharged on the shelf member 80 are configured to be stacked in multiple stages.

Hereinafter, another embodiment of the present invention will be described with reference to the accompanying drawings. This embodiment is the same as the previous embodiment in all contents, and since there are some differences in the structure of the discharge unit 30, hereinafter, in order to avoid duplication, only the parts with differences will be described.

In this embodiment, the discharge unit 30 adjusts the discharging position of the cut drawing member M when discharging the cut drawing member M, so that the drawing member M is stacked in multiple stages on the shelf member 80. Of course, it has a structure that allows the drawing member M to be aligned in a parallel structure in the left and right directions.

More specifically, the discharge unit 30 in this embodiment includes a plurality of conveyor members 100 installed between adjacent support rollers 10 and the plurality of conveyor members 100 as shown in FIGS. 8 to 10 ) It can be illustrated as including a bending member 200 for bending the right end at a certain angle.

That is, when the support roller 10 supporting the cut drawing member M moves to the bottom dead center, the drawing member M is transferred to the conveyor member 100, and the drawing member delivered to the conveyor member 100 ( M) is discharged to the shelf member 80 of the stacking unit 4 by the driving of the conveyor member 100, while the bending member 200 selectively bends the right end of the conveyor member 100 at a certain angle The discharge position of the drawing member M discharged from the conveyor member 100 can be adjusted.

For example, as shown in FIG. 9, when the right end of the conveyor member 100 is not bent and the conveyor member 100 is formed horizontally, the drawing member M moves in parallel to the right end of the conveyor member 100. It is discharged to the rear shelf member 80 and is stacked on the right side of the shelf member 80.

On the other hand, as shown in FIG. 10, when the right end of the conveyor member 100 is bent by the bending member 200, the conveyor member 100 before the drawing member M moves to the right end of the conveyor member 100. ), so they are stacked on the left side of the shelf member 80.

That is, when the drawing member M is discharged by bending the right end of the conveyor member 100 at regular intervals as described above, it is possible to arrange the drawing member M in parallel in the left and right directions on the shelf member 80, thereby limiting shelf life. It provides the advantage of being able to use the area of the member 80 more effectively.

To this end, each of the plurality of conveyor members 100 has a first conveyor roller 110 that is directly connected to the conveyor driving motor 111 and rotates in place, and is spaced apart in parallel to the right side of the first conveyor roller 110 The second conveyor roller 120, the third conveyor roller 130 spaced apart from the right side of the second conveyor roller 120, the first conveyor roller 110, the second conveyor roller 120 and the third conveyor A conveyor belt 140 wound around the roller 130 in an endless track and disposed around the second conveyor roller 120 in a state out of the track of the conveyor belt 140 to support the outer surface of the conveyor belt 140 It can be illustrated as including a fourth conveyor roller 150 that does.

The first conveyor roller 110, the second conveyor roller 120, and the fourth conveyor roller 150 are rotatably fixed in place on the support plate 160, and the third conveyor roller 130 will be described later. Relative rotation is provided by the bending member 200 .

When the first conveyor roller 110 is rotated by the conveyor driving motor 111, the first conveyor roller 110, the second conveyor roller 120, and the third conveyor roller 130 are synchronized by the conveyor belt 140. direction, and in the case of the fourth conveyor roller 150, it may rotate in the opposite direction.

As the conveyor belt 140 operates in an endless track, the drawing member M seated and supported on the conveyor belt 140 may move to the right.

When the third conveyor roller 130 is rotated downward, the conveyor belt 140 may slack downward. At this time, the fourth conveyor roller 150 under the second conveyor roller 120 is ) Since the conveyor belt 140 is supported from the outside to prevent sagging, stable operation of the conveyor belt 140 can be guaranteed even when the conveyor member 100 is bent.

Next, the bending member 200 is connected to each of the conveyor members 100 and can adjust and control the plurality of conveyor members 100 at the same time.

The bending member 200 is shaft-coupled to the first interlocking shaft 210 coupled to the third conveyor roller 130 of each of the plurality of conveyor members 100 and to the rear end of the first interlocking shaft 210 and outward. The second interlocking shaft 220, to which the bending gear 221 is mounted, and the arc-shaped guide sphere 231 are formed through, and the gear teeth 232 to which the bending gear 221 is meshed are formed inside the guide sphere 231 It may be illustrated as including a guide plate 230 formed and a bending motor 240 mounted on the rear end of the second interlocking shaft 220 to drive the second interlocking shaft 220 forward and reverse rotation.

The first interlocking shaft 210 may pass through the center of each third conveyor roller 130 and be integrated with the third conveyor roller 130 .

The second interlocking shaft 220 is coupled coaxially with the first interlocking shaft 210, while the first interlocking shaft 210 is integrally formed with the third conveyor roller 130, the aforementioned conveyor driving motor The rotational force of 111 is transmitted to the second interlocking shaft 220 so that the second interlocking shaft 220 can be rotated arbitrarily. At this time, the rotational force of the conveyor driving motor 111 is transmitted to the second interlocking shaft 220. To prevent this, a slip joint 250 may be formed between the first interlocking shaft 210 and the second interlocking shaft 220 .

That is, the first interlocking shaft 210 and the second interlocking shaft 220 may be coupled to each other via the slip joint 250 .

As shown in FIG. 12, the slip joint 250 is coupled to the front end of the first sleeve 251 coupled to the rear end of the first interlocking shaft 210 and the second interlocking shaft 220, and is internally coupled to the first sleeve. It may be illustrated as including a second sleeve 252 accommodating 251 and a bearing 253 installed between the first sleeve 251 and the second sleeve 252 .

Thus, the first sleeve 251 and the second sleeve 252 are provided to rotate with each other so that the rotational force of the conveyor driving motor 111 is transmitted to the second interlocking shaft 220 or the rotational force of the bending motor 240 is transmitted to the first A structure capable of preventing a power collision phenomenon generated by transmission to the interlocking shaft 210 is provided.

Although not shown, the guide plate 230 may be fixedly installed on the fixed frame, and the bending gear 221 may reciprocate the guide sphere 231 within the formation range of the guide sphere 231 .

That is, when the bending motor 240 rotationally drives the second interlocking shaft 220, the bending gear 221 rotates and guides the guide sphere 231 while being engaged with the gear teeth 232 of the guide sphere 231. In conjunction with this, the first interlocking shaft 210 also becomes a structure that can be moved up and down within the formation range of the guide sphere 231, and when the first interlocking shaft 210 moves up and down, the conveyor member 100 The discharge position of the drawing material M may be adjusted while a portion of the right end of the is bent.

For example, as shown in FIG. 11, when the bending gear 221 is positioned at the top dead center of the guide sphere 231, the third conveyor roller 130 is placed on the same line as the first conveyor roller 110, and the conveyor member ( 100) has a structure in which the right end is not bent, and thus, the drawing member M moves in parallel to the right end of the conveyor member 100 and is then discharged to the shelf member 80 to the right side of the shelf member 80. It is piled up cleanly.

On the other hand, when the bending gear 221 is moved to the bottom dead center along the guide sphere 231 by the drive of the bending motor 240, the right end of the conveyor member 100 is bent downward. Since the ashes M are discharged from the conveyor member 100 before moving to the right end of the conveyor member 100, they are stacked on the left side of the shelf member 80.

At this time, when the right end of the conveyor member 100 is bent downward, the shelf member 80 is moved downward to prevent the third conveyor roller 130 and the shelf member 80 from interfering with each other, and then the shelf member 80 is moved upward again. can be moved to
