Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and in particular to a punching device. Background Art

[0002] The traditional method of punching holes in the wear-resistant pad strip is mainly manual operation, that is, manually using a drilling tool to assist in fixing the guide rail and the wear-resistant pad strip, and then punching holes in the wear-resistant pad strip manually.

[0003] In the prior art, when punching holes in the wear-resistant pads manually, the worker needs to manually adjust the screw rod to control the pressing plate to press or loosen the wear-resistant strips, adjust the distance between the fixed plate and the punching machine, and adjust the telescopic column to control the height of the punching position according to the actual situation. This manual operation has unstable clamping force and large errors, which can easily cause the installed high-molecular polyethylene wear-resistant pads to be uneven, and the operator is prone to fatigue and low work efficiency.

[0004] Furthermore, since the holes are drilled manually, it is not possible to ensure that the intervals between the multiple holes on the wear-resistant pad strip are uniform, which results in a reduction in the quality of the wear-resistant pad strip. Summary of the invention

After completing the punching, the control device can control the second brake assembly to release the fixed strip, and then control the movable part to extend from the fixed part. After the movable part extends a certain distance, the second brake assembly is controlled to clamp the fixed strip again.

[0054] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0055] See also Figure 1 In an embodiment of the present application, a punching device 10 is provided, and the punching device 10 can be used to punch holes in a wear-resistant pad strip. The wear-resistant pad strip can be a high-molecular polyethylene wear-resistant pad strip or a similar wear-resistant pad strip. It is worth noting that after the wear-resistant pad strip is fixed on the punching device 10, the punching device 10 can automatically punch holes uniformly on the wear-resistant pad strip along its length direction. In other words, the punching device 10 provided in the embodiment of the present application can improve the technical problem of uneven punching on the wear-resistant pad strip in the prior art.

[0056] In this embodiment, please refer to Figure 1 and Figure 2The punching device 10 includes a frame 100, a punching assembly 200, a first driving assembly 300 and a control device 400. The frame 100 is used to fix the wear-resistant pad strip; and the frame 100 is provided with a first guide rail 111 and a fixing bar 112 extending along a preset direction; the fixing bar 112 and the first guide rail 111 are arranged in parallel. The punching assembly 200 can be movably connected to the first guide rail 111 to slide along the first guide rail 111; and the punching assembly 200 is used to punch holes on the wear-resistant pad strip. The first driving assembly 300 is used to drive the punching assembly 200 to move on the first guide rail 111, so that the punching assembly 200 moves to a designated position for punching. The control device 400 is used to control the operation of the first driving assembly 300 to drive the punching assembly 200; the control device 400 can also be used to control the punching assembly 200 to punch holes on the wear-resistant pad strip.

[0057] Among them, see Figure 2 , Figure 3 and Figure 4 The first driving component 300 includes a fixed part 320, a movable part 310, a first brake component 330 and a second brake component 340; the fixed part 320 is fixed on the punching component 200, the movable part 310 can be movably arranged on the fixed part 320, and can make linear reciprocating motion along a preset direction; the first brake component 330 is arranged on the fixed part 320 or the punching component 200, and the first brake component 330 is used to clamp or release the fixing strip 112; the second brake component 340 is arranged on the movable part 310, and the second brake component 340 is used to clamp or release the fixing strip 112. The punching assembly 200 is electrically connected to the control device 400, and the control device 400 is used to control the punching assembly 200 to punch holes in the wear-resistant pad strip; the first drive assembly 300 is electrically connected to the control device 400, and the control device 400 is used to control the first brake assembly 330 to selectively clamp or release the fixed strip 112, and the control device 400 is also used to control the second brake assembly 340 to selectively clamp or release the fixed strip 112; the control device 400 is also used to control the movable part 310 to move relative to the fixed part 320.

[0058] When using the punching device 10 to punch holes in the wear-resistant pad strip, the control device 400 can control the movable part 310 to extend relative to the fixed part 320. After extending a certain distance, the second brake assembly 340 can be controlled to clamp the fixed strip 112 to achieve braking of the movable part 310; at this time, the control device 400 controls the first brake assembly 330 to release the fixed strip 112, and then controls the movable part 310 to retract. Since the second brake assembly 340 clamps the fixed strip 112, the movable part 310 is fixed, and the fixed part 320 is pulled toward the movable part 310, thereby driving the punching assembly 200 to move; after the fixed part 320 moves a certain distance, the first brake assembly 330 is controlled to clamp the fixed strip 112, and then the control device 400 can control the punching assembly 200 to punch holes in the wear-resistant pad strip. After the punching is completed, the control device 400 can control the second brake assembly 340 to release the fixing strip 112, and then control the movable portion 310 to extend from the fixing portion 320. After the movable portion 310 extends a certain distance, the second brake assembly 340 is controlled to clamp the fixing strip 112 again. The movable portion 310 is controlled to extend and retract reciprocally in sequence, and at the same time, through the cooperation of the first brake assembly 330 and the second brake assembly 340, the punching assembly 200 can be driven to punch holes at a specified distance, thereby achieving the purpose of evenly punching holes on the wear-resistant pad strip.

[0059] That is, the control device 400 can control the first brake assembly 330 to clamp the fixed strip 112 and the second brake assembly 340 to clamp the fixed strip 112 in turn, so as to fix the fixed portion 320 relative to the fixed strip 112 or fix the movable portion 310 relative to the fixed strip 112 in turn. Thus, when the fixed portion 320 is fixed relative to the fixed strip 112, the movable portion 310 can be moved relative to the fixed portion 320 and the fixed strip 112; when the movable portion 310 is fixed relative to the fixed strip 112, the fixed portion 320 can be moved relative to the movable portion 310 and the fixed strip 112. Thus, the punching assembly 200 can be driven to move intermittently along the wear-resistant pad strip by the movable portion 310 and the fixed portion 320 moving forward in turn. At the same time, by controlling the length of the movable portion 310 extending relative to the fixed portion 320 each time to be fixed, the distance of each movement of the punching assembly 200 can be the same, so that the punching assembly 200 can punch holes evenly. By controlling the punching device 10 to perform punching through the control device 400, the punching process can be automated, thereby improving the punching efficiency.

[0060] In addition, by providing the fixed portion 320, the movable portion 310, the first brake assembly 330 and the second brake assembly 340, the punching assembly 200 can punch holes evenly on the wear-resistant pad strip, and the structure is simple and easy to implement.

[0061] In some embodiments of the present application, the movable part 310 and the fixed part 320 can be set as a pen-shaped cylinder, that is, the cylinder body of the pen-shaped cylinder is the fixed part 320, and the telescopic rod of the pen-shaped cylinder is the movable part 310. It should be understood that in other embodiments of the present application, the movable part 310 and the fixed part 320 can also be set in other ways, for example, the movable part 310 and the fixed part 320 are respectively a rack and a motor structure, and the output end of the motor structure is provided with a gear, and the gear is matched with the rack transmission; the motor structure can be operated to extend the rack, and when the rack is fixed, the motor structure can be operated to move along the rack when the gear rolls along the rack.

[0062] Optionally, in the embodiment of the present application, the fixing strip 112 is in the form of a sheet, which can reduce the space occupied by the fixing strip 112 and also facilitate the clamping of the first brake assembly 330 and the second brake assembly 340. The first brake assembly 330 includes a first seat body 331 and a first cylinder barrel 332; the first cylinder barrel 332 is fixed to the fixing portion 320 or the punching assembly 200, and the first seat body 331 is movably connected to the first cylinder barrel 332; the fixing strip 112 is disposed between the first seat body 331 and the first cylinder barrel 332; and / or, the second brake assembly 340 includes a second seat body and a second cylinder barrel; the second cylinder barrel is fixed to the movable portion 310, and the second seat body is movably connected to the second cylinder barrel; the fixing strip 112 is disposed between the second seat body and the second cylinder barrel.

[0063] The first cylinder 332 can provide a pushing action to the first seat 331, so that the gap between the first seat 331 and the first cylinder 332 is reduced, thereby achieving the purpose of clamping the fixing strip 112; similarly, the second cylinder can provide a pushing action to the second seat, so that the gap between the second seat and the second cylinder is reduced, thereby achieving the purpose of clamping the fixing strip 112. Correspondingly, the first cylinder 332 can also release the first seat 331 to loosen the fixing strip 112; similarly, the second cylinder can also release the second seat to loosen the fixing strip 112.

[0064] It is worth noting that "and / or" means that only the first brake assembly 330 may adopt the arrangement of the first seat body 331 and the first cylinder barrel 332; only the second brake assembly 340 may adopt the arrangement of the second seat body and the second cylinder barrel; or the first brake assembly 330 may adopt the arrangement of the first seat body 331 and the first cylinder barrel 332, and the second brake assembly 340 may adopt the arrangement of the second seat body and the second cylinder barrel. It should be understood that in the case where the first brake assembly 330 or the second brake assembly 340 does not adopt the above-mentioned method, other methods may be used to achieve braking. For example, an electromagnetic component is provided, and it is adsorbed on the fixing bar 112 by powering on to achieve braking, and the magnetism is eliminated by powering off to loosen the fixing bar 112, etc.

[0065] In order to conveniently and accurately control the length of the movable part 310 extending from the fixed part 320, and also to conveniently control the distance the fixed part 320 moves, in this embodiment, the first driving assembly further includes a first position detection device 321 and a second position detection device 322; the first position detection device 321 and the second position detection device 322 are both disposed on the fixed part 320; the first position detection device 321 is used to detect the distance the fixed part 320 moves along a preset direction; the second position detection device 322 is used to detect the distance the movable part 310 extends relative to the fixed part 320;

[0066] The first position detection device 321 and the second position detection device 322 are both electrically connected to the control device 400; the control device 400 is used to control the first brake assembly 330 to clamp the fixed bar 112 when the first position detection device 321 detects that the fixed part 320 moves a preset distance along a preset direction; the control device 400 is also used to control the second brake assembly 340 to clamp the fixed bar 112 when the second position detection distance detects that the movable part 310 extends a preset distance relative to the fixed part 320.

[0067] By setting the first position detection device 321 and the second position detection device 322 on the fixed part 320, the moving distance of the fixed part 320 and the movable part 310 can be detected by the first position detection device 321 and the second position detection device 322 to ensure that the movable part 310 and the fixed part 320 drive the punching assembly 200 to move the same distance each time, thereby evenly punching holes on the wear-resistant pad strip.

[0068] In this example, see Figure 4 The punching device 10 includes a first base 210, a second base 220, a second driving assembly 240 and a puncher 230. The first base 210 is provided with a first sliding seat 211 adapted to the first guide rail 111, and the first sliding seat 211 is slidably matched with the first guide rail 111. The second base 220 is fixedly arranged on the first base 210; and a vertical second guide rail 221 is arranged on the second base 220. The puncher 230 is movably connected to the second guide rail 221 and can slide along the second guide rail 221. The second driving assembly 240 is arranged on the second base 220, and the second driving assembly 240 is connected to the puncher 230 to drive the puncher 230 to move up and down along the second guide rail 221.

[0069] The first base 210 provides bearing for the second base 220, the second drive assembly 240 and the punch 230, so that the first base 210 can drive the second base 220, the second drive assembly 240 and the punch 230 to move when moving. The second base 220 can provide bearing for the second drive assembly 240 and the punch 230, thereby ensuring the assembly stability of the second drive assembly 240. It is also convenient for the second drive assembly 240 to drive the punch 230 to move up and down.

[0070] When the movable part 310 is fixed on the fixed strip 112 by the second brake assembly 340, the movable part 310 retracts to drive the fixed part 320 to move, and at the same time drives the first base 210 to move. After the first base 210 moves to the specified position, the control device 400 can control the second drive assembly 240 to drive the punch 230 to move downward along the second guide rail 221 to punch holes in the wear-resistant pad strip. After the punching is completed, the punch 230 can be controlled to move upward along the second guide rail 221 to prepare for the next punching. It has a simple structure, is easy to implement, and can reduce costs.

[0071] In the embodiment of the present application, the first base 210 and the second base 220 are substantially L-shaped.

The mounting plate 232 can provide a bearing function for the machine body 231, ensuring the stability of the machine body 231 when punching holes through the punching piece, so as to ensure that the punching machine 230 performs stable punching.

[0073] Optionally, the punching machine 230 further includes a pressing plate; the pressing plate is arranged below the second mounting portion 2322, and is used to press the wear-resistant pad strip when the punching member punches holes; the punching member passes over the pressing plate to punch holes. During the punching process, the pressing plate can press the wear-resistant pad strip downward to ensure the stability of the wear-resistant pad strip, thereby enabling stable punching and preventing the problem of positional displacement of the wear-resistant pad strip causing offset of the punching.

[0074] In addition, the second driving assembly 240 can be a standard cylinder, and the cylinder body of the standard cylinder is fixed on the second base 220, and the telescopic rod of the standard cylinder is connected to the punch 230, so that the punch 230 can be driven to move up and down by the telescopic movement of the telescopic rod. It should be understood that in other embodiments of the present application, the second driving assembly 240 can also be a motor.

[0075] In this example, see Figure 5 The frame 100 includes a frame body 110, a clamping device 120 and a positioning assembly 130. The clamping device 120 and the positioning assembly 130 are both arranged on the frame body 110; the first guide rail 111 and the fixing bar 112 are both arranged on the frame body 110. The clamping device 120 can be used to clamp and tighten the wear-resistant pad strip, and the positioning assembly 130 can be used to provide further positioning for the wear-resistant pad strip to ensure that the wear-resistant pad strip is stably fixed on the frame body 110.

[0076] Among them, the clamping device 120 includes a first clamping component 121 and a second clamping component 122; the first clamping component 121 and the second clamping component 122 are respectively arranged at both ends of the frame 110 along a preset direction, and the first clamping component 121 and the second clamping component 122 are used to clamp and tighten the wear-resistant pad strip along the preset direction.

[0077] Optionally, the first clamping assembly 121 includes a first support seat 1211 and a first clamping member 1212; the first support seat 1211 is fixedly connected to the frame 110; the first clamping member 1212 is rotatably connected to the first support seat 1211, and a gap is formed between the first clamping member 1212 and the first support seat 1211 to clamp the wear-resistant pad strip; the first clamping member 1212 is provided with a first clamping tooth 1213, and the first clamping member 1212 is used to rotate relative to the first support seat 1211 to press the wear-resistant pad strip through the first clamping tooth 1213. In the first clamping assembly 121, the wear-resistant pad strip can be placed in the gap between the first clamping member 1212 and the first support seat 1211, and the first clamping member 1212 is rotated so that the clamping teeth on the first clamping member 1212 press the wear-resistant pad strip on the first support seat 1211, thereby clamping the wear-resistant pad strip. In other words, the first clamping assembly 121 forms a structure similar to a belt lock. It should be understood that in other embodiments, other methods may be used to clamp the wear-resistant pad strip, for example, by pressing the wear-resistant pad strip with a hydraulic press.

[0078] In addition, the second clamping assembly 122 includes a second support seat 1221, a second clamping piece 1222 and a tensioning cylinder 1224; the second support seat 1221 is fixedly connected to the frame 110; the second clamping piece 1222 is rotatably matched with the second support seat 1221, and a gap is formed between the second clamping piece 1221 to clamp the wear-resistant pad strip; the second clamping piece 1222 is provided with a second clamping tooth 1223, and the second clamping piece 1222 is used to rotate relative to the second support seat 1221 so that the second clamping tooth 1223 presses the wear-resistant pad strip; the tensioning cylinder 1224 is fixedly connected to the second clamping piece 1222, and the tensioning cylinder 1224 is used to pull the wear-resistant pad strip to tighten the wear-resistant pad strip. In the second clamping assembly 122, the second clamping member 1222 is rotated so that the second clamping teeth 1223 press the wear-resistant pad strip onto the second support seat 1221, thereby clamping the wear-resistant pad strip. Then, the wear-resistant pad strip is pulled by the tensioning cylinder 1224, so that the wear-resistant pad strip is tightened.

[0079] Therefore, by setting the first clamping assembly 121 and the second clamping assembly 122, the wear-resistant pad strip can be clamped and tightened to ensure the stability of the wear-resistant pad strip during the punching process, thereby facilitating the punching of the wear-resistant pad strip.

[0080] In this embodiment, the positioning assembly 130 includes a plurality of push cylinders 131 and a positioning member 132. The positioning member 132 is fixedly connected to the frame 110, and the positioning member is arranged in parallel with the first guide rail 111. The plurality of push cylinders 131 are arranged in a preset direction, and the plurality of push cylinders 131 are used to push the wear-resistant pad strip to abut against the positioning member 132 along its width direction. The wear-resistant pad strip can be fixed and tightened by the clamping device 120, and then the wear-resistant pad strip is pushed to abut against the positioning member 132 along its width direction by the plurality of push cylinders 131, so as to ensure that the wear-resistant pad strip is fixed on the frame 100, and the stability of the wear-resistant pad strip during the punching process can be improved to ensure uniform punching. The wear-resistant pad strip can be prevented from deviating by the plurality of push cylinders 131 cooperating with the positioning member 132.

[0081] Optionally, the positioning member 132 includes a connecting portion 1321 and a positioning portion 1322; the connecting portion 1321 is fixedly connected to the frame 110; the positioning portion 1322 is disposed on the connecting portion 1321, and the positioning portion 1322 is vertically disposed; the pushing cylinder 131 is used to push the wear-resistant pad against the positioning portion 1322. The overall stability of the positioning member 132 can be ensured by connecting the connecting portion 1321 with the frame 110; when multiple pushing cylinders 131 push the wear-resistant pad, the wear-resistant pad can be against the positioning portion 1322, thereby ensuring the stability of the wear-resistant pad being fixed.

[0082] Based on the punching device 10 provided above, the working process of punching using the punching device 10 is roughly as follows:

[0083] The wear-resistant pad strip is placed next to the positioning portion 1322 of the positioning member 132, and then the two ends of the wear-resistant pad strip are clamped and tightened by the first clamping assembly 121 and the second clamping assembly 122 respectively. Then the punching control program of the control device 400 is triggered to start punching. The control device 400 realizes the intermittent movement of the punching assembly 200 along the wear-resistant pad strip by controlling the movable part 310, the fixed part 320, the first brake assembly 330 and the second brake assembly 340. Whenever the fixed part 320 moves into place, the first brake assembly 330 is braked to fix the fixed part 320 relative to the fixed strip 112. At this time, the punching machine 230 can be controlled to punch holes on the wear-resistant pad strip. By moving the movable part 310 and the fixed part 320 in turn, the control device 400 can intermittently punch holes on the wear-resistant pad strip. After completing multiple punching, the operation is stopped. After the operator completes the inspection, the wear-resistant pad strip can be removed.

[0084] In addition, in the embodiment of the present application, the punching device 10 can be transported by a light rod slide rail transmission method, which is light in weight, high in strength, occupies less space, has low noise, can bypass other equipment during assembly, has high mechanical efficiency, can be connected and disassembled, and is easy to repair and maintain.

[0085] To sum up, during the process of the punching device 10 provided in the embodiment of the present application punching holes in the wear-resistant pad strip, the control device 400 can control the movable part 310 to extend relative to the fixed part 320. After extending a certain distance, the second brake assembly 340 can be controlled to clamp the fixed strip 112 to achieve braking of the movable part 310; at this time, the control device 400 controls the first brake assembly 330 to release the fixed strip 112, and then controls the movable part 310 to retract. Since the second brake assembly 340 clamps the fixed strip 112, the movable part 310 is fixed, and the fixed part 320 is pulled toward the movable part 310, thereby driving the punching assembly 200 to move; after the fixed part 320 moves a certain distance, the first brake assembly 330 is controlled to clamp the fixed strip 112, and then the control device 400 can control the punching assembly 200 to punch holes in the wear-resistant pad strip. After the punching is completed, the control device 400 can control the second brake assembly 340 to release the fixing strip 112, and then control the movable portion 310 to extend from the fixing portion 320. After the movable portion 310 extends a certain distance, the second brake assembly 340 is controlled to clamp the fixing strip 112 again. The movable portion 310 is controlled to extend and retract reciprocally in sequence, and at the same time, through the cooperation of the first brake assembly 330 and the second brake assembly 340, the punching assembly 200 can be driven to punch holes at a specified distance, thereby achieving the purpose of evenly punching holes on the wear-resistant pad strip.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
