Description

Cutting apparatus for drawing machine}

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

A drawing device is required when manufacturing semi-finished products such as metal products, especially copper busbars, non-ferrous metal billets, pipes, and round bars.

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

At this time, the drawn material that is continuously drawn is generally cut to a predetermined length according to the purpose at the drawn material cutting line, or rolled into a roll and transported to a post-process.

Meanwhile, in the conventional drawn material cutting line, the worker manually measured the length of the drawn material, marked the cutting position, and then directly cut the cutting position using a tool such as a hand grinder, so manual measurement errors occurred in the finished product. Because the precision of the length was low and the cutting finish was not neatly achieved, not only did it reduce marketability, but it also had a negative impact on productivity.

In addition, there was a problem that safety accidents frequently occurred because workers were always exposed to dangerous situations due to drawn materials drawn at high temperatures.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that identical members in each drawing may be indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

Prior to a detailed description of the invention, for convenience of explanation, if a non-strict direction standard is specified with reference to the accompanying drawings, in the state shown in Figures 1 to 3, up and down (y), left and right (x), It is divided into before and after (z), and the direction is specified according to this standard in descriptions related to other drawings.

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 this embodiment is installed adjacent to the drawing machine (D), continuously cuts the drawing material (M) drawn from the drawing machine (D) to a set length, and stacks the cut drawing material (M) in multiple stages. You can do it.

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

First, the guide unit (1) receives the drawing material (M) drawn from the drawing machine (D) and guides it backwards, and guides the cut drawing material (M) to the right to discharge it toward the stacking unit (4). can do.

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

More specifically, the guide unit 1 includes a plurality of support rollers 10 that support the lower part of the drawn material M being guided backward, and an elevating part 20 that elevates the plurality of support rollers 10 up and down. And when the drawn material (M) is seated as the plurality of support rollers (10) descend, it may be illustrated as including a discharge portion (30) that discharges the drawn material (M) to the right.

Considering the shape of the drawn material (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 drawn material (M) in a balanced manner.

At this time, the support roller 10 can be lifted up and down by the lifting part 20, which will be described later, while supporting the drawn material M. When the support roller 10 is located at top dead center, the support roller 10 is formed to be higher than the conveyor member 100 of the discharge portion 30, which will be described later, so that the drawn material (M) can be spaced upward from the conveyor member 100, and the support roller 10 moves to the bottom dead center. When this happens, the support roller 10 is formed to be lower in height than the upper surface of the conveyor member 100, so that the drawn material (M) supported on the support roller 10 is spaced apart from the support roller 10 and then placed on the conveyor member 100. It becomes a transmitted structure.

Accordingly, the drawn material (M) can be discharged toward the stacking unit (4) along the discharge direction of the discharge unit (30).

The lifting unit 20 supports the plurality of support rollers 10 and synchronously rotates (rotates) the plurality of support rollers 10 at a certain angle so that the support rollers 10 can be lifted up and down.

More specifically, as shown in FIGS. 4 to 5, the lifting unit 20 includes a plurality of first rotation shafts 21 installed in parallel with the support rollers 10, each of the plurality of support rollers 10. A plurality of connection brackets 23 that connect and couple the first rotation shafts 21 to each other at a predetermined distance apart, are disposed across the lower portions of the plurality of first rotation shafts 21 in the front-back direction, and have a connection stand 25 at the bottom. ) is provided, a plurality of interlocking links 26 connecting the plurality of first rotation shafts 21 and the interlocking frame 24, and installed at the lower part of the interlocking frame 24 and the connection bar 25 ) and a first actuator 27 that reciprocates the interlocking frame 24.

First, the first rotation shaft 21 may be installed on a lifting frame (not shown) so that both ends can rotate in place via fixed bearings 22.

The connecting brackets 23 form a pair and connect one support roller 10 to one first rotation shaft 21.

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

Accordingly, when the first rotation shaft 21 rotates at a certain angle, the support roller 10 can be rotated along the rotation direction of the first rotation shaft 21.

The interlocking frame 24 is made of a frame-shaped member extending long in the front-back direction, and each interlocking link 26 can be connected to it at the appropriate location. At this time, the upper end of the interlocking link 26 may be 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. In this case, the cylinder body of the first actuator 27 is rotatably connected and installed on a fixed frame without separate reference numerals, and the rod's The end may be rotatably connected 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 first rotation axis 21, thereby causing a plurality of The support rollers 10 may be rotated based on the first rotation axis 21.

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 a rotational movement of the first rotation shaft 21 by the interlocking frame 24 and the interlocking link 26. By rotating the first rotation shaft 21 counterclockwise, the plurality of support rollers 10 can be interlocked and moved to top dead center. Conversely, when the first actuator 27 is compressed, the first rotation shaft 21 By rotating clockwise, the plurality of support rollers 10 can be moved 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 drawn material M supported on the support roller 10 may also be rotated downward and seated in the discharge unit 30.

The discharge unit 30 moves the drawn 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 normal conveyor structure, and is installed between adjacent support rollers 10 to support and move the drawn material M in a balanced manner.

Next, the brake unit (2) is installed to be able to move back and forth on the upper part of the guide unit (1), and stops the drawn material (M) being guided backward at a set position before cutting the drawn material (M). It plays a role in fixing. That is, the length of the drawn material (M) to be cut can be adjusted by adjusting the front and rear position of the brake unit (2).

At this time, the brake unit (2) blocks the rear end of the drawn material (M) to stop and fix the drawn material (M) on the guide unit (1), and the drawn material (M) stopped and fixed in this way is connected to the cutting unit (3). ) can be cut.

More specifically, as shown in FIGS. 2 and 6, the brake unit 2 is connected to a screw shaft 40 extending in the front-back direction on the left side of the guide unit 1, and the screw shaft 40. A fuselage 50 that is provided to be capable of reciprocating in the forward and backward direction along the screw shaft 40, a stopper 60 formed on the fuselage 50 and in which the rear end of the drawn material (M) is contacted and supported, and the stopper (60) ) and may be exemplified as including a signal generator 70 that generates a deceleration signal that causes the drawing speed of the drawing machine (D) to slow down when the drawn material (M) is contacted.

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

When the fuselage 50 is fixed in position, the stopper 60 and the signal generating unit 70 can also be fixed in position, and the drawn material (M) guided by the guide unit 1 is positioned so that the signal generating unit 70 is fixed in position. After passing, it can be stopped and fixed by the stopper (60).

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

That is, by controlling the relative movement of the fuselage 50 forward or backward with respect to the position-fixed cutting unit 3, the length of the drawn material M to be cut can be adjusted to be longer or shorter, and further, the drawn material ( A structure in which the drawn material (M) can be stopped and fixed at an appropriate position by moving and fixing the fuselage (50) at the desired position without manually measuring the length of the drawn material (M) and cutting the drawn material (M) to the desired length. is equipped.

The position adjustment of the fuselage 50 can be controlled wirelessly by a separate control means. When the operator inputs a value into the control means, the control means links the screw shaft 40, the LM guide structure, and the encoder to control the fuselage ( 50) can be controlled to move to a position corresponding to the value entered by the operator.

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

The signal generator 70 is rotatably coupled to the front of the fuselage 50 and is coupled to a circuit breaker 71 with which the drawing material (M) is in contact, between the fuselage 50 and the circuit breaker 71 and the drawing material (M). It may be exemplified as including a second actuator 72 that rotates the circuit breaker 71 rotated by ) to its original position and a rotation detection sensor (not shown) that detects the rotation of the circuit breaker 71 and generates a deceleration signal. there is.

The drawn material M may be in line contact with the breaker 71 placed in front of the stopper 60 before being contacted and supported by the stopper 60, as shown in FIG. 6A, and as shown in FIG. 6B. Likewise, the moment the drawn material (M) contacts the circuit breaker (71), the circuit breaker (71) rotates in the direction of the fuselage (50), thereby establishing a structure that does not interfere with the drawing direction of the drawn material (M).

When the breaker (71) is rotated by the drawing material (M), the rotation detection sensor detects this, generates a deceleration signal, and transmits it to the drawing machine (D).

Since the rotation detection sensor, not separately shown, can be implemented in various ways to detect the rotation of the circuit breaker 71, the installation location and structure are not specifically limited.

When a deceleration signal is sent to the drawing machine (D), the drawing machine (D) controls the drawing speed of the drawn material (M) to be reduced, thereby preventing the drawn material (M) from colliding strongly with the stopper (60). constitutes.

Meanwhile, when the drawn material (M) is cut and discharged toward the stacking unit (4), the circuit breaker (71), which was rotated toward the fuselage (50), is rotated by the second actuator (72) again as shown in FIG. 6A. It can be set to its original position.

Next, the stacking unit 4 plays the role of stacking the cut drawn material M when it is guided to the right by the guide unit 1 and discharged.

The stacking unit (4) is arranged on the right side of the guide unit (1) to receive the cut drawn material (M) and stack it in multiple stages. In particular, the drawn material (M) is continuously discharged from the guide unit (1). It has a structure that allows it to be stacked in multiple stages up and down.

For this purpose, the stacking unit 4 is illustrated as including a shelf member 80 on which the drawn material M is stacked and a third actuator 90 that lifts the shelf member 80 in the vertical direction. Accordingly, the shelf member 80 can be appropriately lifted 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 explained by taking a simple driving process of the cutting device for a drawing machine as an example.

First, the worker sets the guide unit (1) so that the support roller (10) is located at top dead center, and sets the brake unit (2) to position the fuselage (50) in an appropriate position considering the length of the drawn material (M) to be cut. After setting, when the drawing machine (D) starts drawing, the drawn material (M) is guided backward on the support roller (10) by the drawing pressure of the drawing machine (D).

When the drawn material (M), which has been guided backward, comes into contact with the circuit breaker (71), the signal generator 70 generates a deceleration signal by generating a contact point and transmits it to the drawn machine (D). At this time, the drawing machine (D) momentarily lowers the drawing pressure of the drawing material (M) based on the deceleration signal to reduce the drawing speed of the drawing material (M).

When the drawn material (M) moves further rearward and contacts the stopper (60), the rearward movement of the drawn material (M) is stopped, and at the same time, the cutting unit (3) operates to cut the front end portion of the drawn material (M). Cut.

Accordingly, the drawn material (M) is cut to a length corresponding to the distance between the stopper (60) and the cutting unit (3).

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

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

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

At this time, the upper and lower heights of the shelf member 80 are appropriately adjusted so that the drawn materials M continuously discharged on the shelf member 80 can be stacked in multiple stages.

Hereinafter, another embodiment of the present invention will be described with reference to the accompanying drawings. This embodiment has all the same content as the above-described embodiment, but there are some differences in the structure of the discharge unit 30. Therefore, to avoid duplication, only the parts where there are differences will be described below.

In this embodiment, the discharge unit 30 adjusts the discharge position of the drawn material (M) when discharging the cut drawn material (M) so that the drawn material (M) is stacked in multiple stages on the shelf member (80). Of course, it has a structure that allows the drawn material (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 as shown in FIGS. 8 to 10, and the plurality of conveyor members 100 ) may be illustrated as including a bending member 200 that bends the right end of the unit at a certain angle.

That is, when the support roller 10 supporting the cut drawn material (M) moves to the bottom dead center, the drawn material (M) is delivered to the conveyor member 100, and the drawn material delivered to the conveyor member 100 ( M) is discharged to the shelf member 80 of the stacking unit 4 by driving 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 drawn material (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 drawn material (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 drawing material (M) moves to the right end of the conveyor member 100 before moving to the right end of the conveyor member 100. ), so it is placed biased on the left side of the shelf member (80).

In other words, when the right end of the conveyor member 100 is bent at a certain cycle as above to discharge the drawn material (M), the drawn material (M) can be aligned in parallel in the left and right directions on the shelf member 80, thereby limiting the shelf. This provides the advantage of being able to use the area of the member 80 more effectively.

For this purpose, each of the plurality of conveyor members 100 includes a first conveyor roller 110 that is directly connected to the conveyor drive motor 111 and rotates in place, and is arranged parallel to the right and spaced apart from the first conveyor roller 110. The second conveyor roller 120, the third conveyor roller 130 spaced apart to the right 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 infinite orbit is disposed around the second conveyor roller 120 in a state outside the orbit of the conveyor belt 140 to support the outer surface of the conveyor belt 140. It may be illustrated as including a fourth conveyor roller 150.

The first conveyor roller 110, the second conveyor roller 120, and the fourth conveyor roller 150 are fixed on the support plate 160 so that they can rotate in place, and the third conveyor roller 130 will be described later. It is provided to enable relative rotation by the bending member 200.

When the first conveyor roller 110 rotates by the conveyor drive 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. It rotates in the opposite direction, and in the case of the fourth conveyor roller 150, it can rotate in the opposite direction.

As the conveyor belt 140 operates in an endless orbit, the drawn material M seated and supported on the conveyor belt 140 may be moved to the right.

When the third conveyor roller 130 is rotated downward, the conveyor belt 140 may sag downward. In this case, the fourth conveyor roller 150 moves from the lower part of the second conveyor roller 120 to the conveyor belt 140. ), the conveyor belt 140 is supported from the outside to prevent sagging, thereby ensuring stable operation of the conveyor belt 140 even when the conveyor member 100 is bent.

Next, the bending member 200 is installed and connected to each conveyor member 100, so that a plurality of conveyor members 100 can be adjusted and controlled simultaneously.

The bending member 200 is axially coupled to a 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 extends outward. A second interlocking shaft 220 on which the bending gear 221 is mounted, an arc-shaped guide hole 231 is formed through it, and a gear tooth 232 with which the bending gear 221 meshes is formed inside the guide hole 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 rotate the second interlocking shaft 220 in forward and reverse directions.

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 coaxially connected to the first interlocking shaft 210, while the first interlocking shaft 210 is integrated with the third conveyor roller 130, and the conveyor drive motor described above 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 drive 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 jointed to each other via the slip joint 250.

As shown in FIG. 12, the slip joint 250 is coupled to the first sleeve 251 coupled to the rear end of the first interlocking shaft 210 and the front end of the second interlocking shaft 220, and is connected to the inside of the first sleeve 251. 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.

Accordingly, the first sleeve 251 and the second sleeve 252 are provided to rotate around each other so that the rotational force of the conveyor drive 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 is provided to prevent power collisions that occur when power is transmitted to the interlocking shaft 210.

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

That is, when the bending motor 240 rotates the second interlocking shaft 220, the bending gear 221 rotates and is engaged with the gear teeth 232 of the guide sphere 231 and guides the guide sphere 231. And in conjunction with this, the first interlocking shaft 210 also has a structure that can be lifted up and down within the formation range of the guide sphere 231, and when the first interlocking shaft 210 is lifted up and down, the conveyor member 100 The discharge position of the drawn material (M) can be adjusted by bending a portion of the right end.

For example, as shown in Figure 11, when the bending gear 221 is located 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 drawn material (M) moves in parallel to the right end of the conveyor member 100 and is then discharged to the shelf member 80 and is placed on the right side of the shelf member 80. It is neatly piled up.

On the other hand, when the bending gear 221 moves to the bottom dead center along the guide member 231 by driving the bending motor 240, the right end of the conveyor member 100 is bent downward, and thus the drawing is performed. Since the material (M) is discharged from the conveyor member 100 before moving to the right end of the conveyor member 100, it is biasedly placed on the left side of the shelf member 80.

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