DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] An embodiment of a disposable punching device of the present invention, as Figures 1 to 10 shown.

[0030] A disposable punching device for punching a metal part 100 includes a processing table 200, a punching mechanism 300 and a support mechanism 400. The support mechanism 400 includes a rotating block 410, four support plates 420 and four follower blocks 430. The rotating block 410 is rotatably arranged on the processing table 200 around a first direction, and the first direction is a vertical direction. The four support plates 420 are all arranged along the first direction and are located on the outside of the rotating block 410. The side close to the vertical center axis of the rotating block 410 along the second direction is called the inner side, and the side away from the vertical center axis of the rotating block 410 is called the outer side. The second direction is perpendicular to the first direction, and the second direction is a horizontal direction.

[0031] The metal part 100 is a square thin-walled structure. The metal part 100 is arranged on the processing table 200 along the first direction and is located outside the four support plates 420. The four support plates 420 are arranged one by one with the four side walls of the metal part 100. In the initial state, the support plates 420 do not abut the side walls of the metal part 100 corresponding to the support plates 420. Each support plate 420 can move along the second direction and abut the side wall of the metal part 100 corresponding to the support plates 420. The four follower blocks 430 are all arranged on the rotating block 410. In the initial state, the four follower blocks 430 are all located in the space surrounded by the four support plates 420. The rotation of the rotating block 410 around the first direction can cause the four follower blocks 430 to move along the second direction. After the support plates 420 move along the second direction to abut the side walls of the metal part 100 corresponding to the support plates 420, the four follower blocks 430 can be respectively inserted between two support plates 420 arranged adjacent to each other around the first direction. The punching mechanism 300 is installed on the processing table 200, located outside the metal part 100 and capable of punching the metal part 100. The punching mechanism 300 is a prior art and will not be described in detail herein.

[0032] Specifically, a motor is disposed on the processing table 200 , and the rotating block 410 is fixedly installed at the output end of the motor. The rotating block 410 is driven by the motor to rotate around a first direction.

[0033] The present embodiment provides a support mechanism 400. When in use, after the metal part 100 is placed on the processing table 200 and sleeved on the support mechanism 400, the four support plates 420 are driven to move along the second direction toward the side wall of the metal part 100 corresponding to the support plate 420 until each support plate 420 abuts against the side wall of the metal part 100 corresponding to the support plate 100. At the same time, the rotating block 410 is driven to rotate around the first direction. When the support plate 420 moves along the second direction until it abuts against the side wall of the metal part 100 corresponding to the support plate 100, the four follower blocks 430 can be respectively inserted between the two support plates 420 adjacent to each other in the first direction to complete the positioning and support of the metal part 100. The four follower blocks 430 are used to fill the positions of the two support plates 420 adjacent to each other in the first direction, so as to avoid the situation in which the distance between the two support plates 420 adjacent to each other in the first direction gradually increases during the movement of the support plate 420 along the second direction, thereby causing unstable support. The four support plates 420 and the four follower blocks 430 can enclose a relatively stable structure to improve the positioning and support effect of the metal part 100. After the support plates 420 and the follower blocks 430 are moved, the punching mechanism 300 can be used to punch the side walls of the metal part 100.

[0034] In this embodiment, four hydraulic telescopic cylinders 440 are arranged on the rotating block 410, and the four hydraulic telescopic cylinders 440 are evenly distributed around the first direction on the rotating block 410, and the four hydraulic telescopic cylinders 440 are arranged one by one corresponding to the four support plates 420, and each hydraulic telescopic cylinder 440 can drive the corresponding support plate 420 to move in the second direction.

[0035] Furthermore, four punching mechanisms 300 are provided, and the four punching mechanisms 300 are provided in one-to-one correspondence with the four side walls of the metal component 100 . The punching mechanisms 300 are used to punch the side walls of the metal component 100 to which they are provided.

[0036] By providing four punching mechanisms 300 , after the supporting mechanism 400 completes supporting the four side walls of the metal member 100 , the four punching mechanisms 300 can complete punching of the four side walls of the metal member 100 at one time, thereby improving the punching efficiency.

[0037] In this embodiment, the rotating block 410 includes an upper top plate 418, a push block 416 and a lower bottom block 419. The upper top plate 418, the push block 416 and the lower bottom block 419 are coaxially arranged in sequence in the first direction and fixedly connected. The upper top plate 418, the push block 416 and the lower bottom block 419 are an integrally formed structure, and the upper top plate 418 is located at the upper end of the push block 416. A moving space is defined between the upper top plate 418, the push block 416 and the lower bottom block 419.

[0038] The upper end of the lower bottom block 419 is provided with a moving groove 417, which includes four arcuate edges, which are sequentially connected around the first direction on the rotating block 410. The arcuate edge has a concave surface and a convex surface, and the convex surface is arranged toward the vertical center axis of the rotating block 410.

[0039] The push block 416 has four outer peripheral walls, and all of the four outer peripheral walls are arc surfaces. The four outer peripheral walls of the push block 416 are arranged in one-to-one correspondence with the four arc edges, and the outer peripheral wall of each push block 416 is parallel to the corresponding arc edge. The point on the outer peripheral wall of the push block 416 that is closest to the vertical center axis of the rotating block 410 along the second direction is called an inner point, and the point that is farthest from the vertical center axis of the rotating block 410 along the second direction is called an outer point.

[0040] The four follower blocks 430 are all located in the moving space, and the four follower blocks 430 are arranged in a one-to-one correspondence with the four outer peripheral walls of the push block 416. In the initial state, the inner end of each follower block 430 abuts against the inner point of the outer peripheral wall of the corresponding push block 416, and the rotation of the rotating block 410 can cause the inner end of the follower block 430 to slide in the moving groove 417 and slide from the corresponding inner point to the outer point, and when the inner end of the follower block 430 slides to the corresponding outer point, the support plate 420 can abut against the side wall of the corresponding metal part 100, and the four follower blocks 430 can be respectively inserted between two support plates 420 adjacent to each other around the first direction.

[0041] Specifically, a slider is provided at the inner end of each follower block 430, and the slider is spherical. The four sliders are arranged one by one corresponding to the four outer peripheral walls of the push block 416. In the initial state, each slider abuts against the inner point of the outer peripheral wall of the corresponding push block 416, and the rotation of the rotating block 410 can cause the slider to slide in the moving groove 417 and slide from the corresponding inner point to the outer point, and when the slider slides to the corresponding outer point, the support plate 420 can abut against the side wall of the corresponding metal part 100, and the four follower blocks 430 can be respectively inserted between two support plates 420 adjacent to each other around the first direction.

[0042] See attached Figure 6 and attached Figure 7 As shown, the concave part of the arc surface on the push block 416 is the point closest to the vertical axis of the rotating block 410 along the second direction, that is, the inner point. The two ends of the arc surface around the first direction are the points farthest from the vertical axis of the rotating block 410 along the second direction, that is, the outer points. The rotating block 410 is rotated around the first direction to drive the push block 416 to rotate, and the outer peripheral wall surface of the push block 416 pushes the slider to slide along the arc surface of the outer peripheral wall surface, so that the follower block 430 can slide in the moving groove 417, and then the follower block 430 can cooperate with the support plate 420 to extend. That is, the follower block 430 will be extended from the attached Figure 7The status shown moves to the Figure 6 Status shown.

[0043] In this embodiment, a corrugated block 450 is disposed at the lower end of the support plate 420, and the corrugated block 450 is disposed along the second direction. A corrugated groove 210 is provided on the processing table 200, and the corrugated groove 210 is disposed along the second direction. The corrugated block 450 and the corrugated groove 210 are disposed face to face in the first direction, and the size of the corrugated groove 210 in the second direction is larger than the size of the corrugated block 450 in the second direction, and the support plate 420 can move in the second direction with the hydraulic telescopic cylinder 440, and can move relative to the hydraulic telescopic cylinder 440 in the first direction.

[0044] Specifically, a clamping block is fixedly connected to the output end of the hydraulic telescopic cylinder 440, and a clamping slot is opened on the support plate 420. The clamping slot is arranged along the first direction and is clamped with the clamping block, so that the support plate 420 can move in the second direction with the hydraulic telescopic cylinder 440, and can move in the first direction relative to the hydraulic telescopic cylinder 440.

[0045] In this embodiment, a corrugated block 450 is arranged at the lower end of the support plate 420, and the corrugated block 450 is matched with the corrugated groove 210 arranged on the processing table 200, so that when the support plate 420 moves along the second direction toward the side wall of the metal part 100 correspondingly arranged thereto, the support plate 420 will continuously move up and down under the urging of the corrugated block 450 and the corrugated groove 210. This arrangement is because when the operator places the metal part 100 on the processing table 200, due to certain errors in manual operation, the metal part 100 may not be completely coaxial with the space enclosed by the four support plates 420, or even if the two are coaxial, the entire metal part 100 may be offset around the first direction, that is, the metal part 100 is placed crookedly. The support plate 420 is moved in the second direction while vibrating up and down by the hydraulic telescopic cylinder 440 arranged on the rotating block 410. During the movement of the support plate 420, the relative position between the support plate 420 and the side wall of the corresponding metal part 100 can be continuously adjusted with the support plate 420 as a reference, so that the support plate 420 can straighten the side wall of the corresponding metal part 100, and the support plate 420 can fit the side wall of the corresponding metal part 100, thereby ensuring the positioning effect of the support plate 420 on the metal part 100 and improving the stability of the support plate 420 in supporting the metal part 100.

[0046] In this embodiment, the support plate 420 includes an upper plate body 421 and a lower plate body 422, which are arranged in sequence in the first direction, the upper plate body 421 is located above the lower plate body 422, and the size of the upper plate body 421 in the first direction is larger than the size of the lower plate body 422 in the first direction. The upper plate body 421 and the lower plate body 422 are connected by a first elastic member 423, which is arranged along the first direction and is a spring. The corrugated block 450 is arranged at the lower end of the lower plate body 422.

[0047] Specifically, a slot is provided at the lower end of the upper plate 421, and the lower plate 422 is inserted into the slot. The slot is provided on the upper plate 421, and the hydraulic telescopic cylinder 440 can drive the upper plate 421 to move, and drive the lower plate 422 to move through the upper plate 421, so that the entire support plate 420 moves.

[0048] Furthermore, each support plate 420 is provided with a clearance hole 424 , and the size of the clearance hole 424 is equal to the size of the hole to be punched on the side wall of the metal component 100 .

[0049] By providing an upper plate body 421 and a lower plate body 422, and providing a first elastic member 423 between the upper plate body 421 and the lower plate body 422, when the upper plate body 421 and the lower plate body 422 move along the second direction, the corrugated block 450 on the lower plate body 422 will cooperate with the corrugated groove 210, thereby driving the lower plate body 422 to move up and down, and driving the upper plate body 421 to move up and down through the first elastic member 423, but due to the shock absorbing effect of the first elastic member 423, the overall vibration amplitude of the support plate 420 will be reduced, thereby avoiding the situation that if the overall vibration amplitude of the support plate 420 is too large, the support plate 420 will not only fail to further fit with the side wall of the metal component 100, but also the metal component 100 may be further deformed due to the vibration of the support plate 420.

[0050] Furthermore, the provision of the clearance hole 424 enables the punching mechanism 300 to completely penetrate the side wall of the metal part 100 when punching the side wall of the metal part 100, and further extend the punching mechanism 300 into the clearance hole 424 to ensure the quality of the punching. However, if the vibration amplitude of the support plate 420 is too large and exceeds the error range of the clearance hole 424 in the first direction, the hole punched on the side wall of the metal part 100 will be misaligned with the clearance hole 424 when the punching mechanism 300 punches the side wall of the metal part 100. Therefore, by reducing the vibration amplitude of the support plate 420 through the first elastic member 423, it is possible to prevent the punched hole from being misaligned with the clearance hole 424 and thus affecting the quality of the punching.

[0051] In this embodiment, a rotating groove 411 is formed on the rotating block 410, and the rotating groove 411 is located below the moving space. The rotating groove 411 is an annular groove and is coaxially arranged with the rotating block 410. Rotating gear rings 412 are arranged on the upper and lower walls where the rotating groove 411 is located. The two rotating gear rings 412 are coaxial with the rotating block 410 and are arranged around the first direction in the rotating groove 411. The two rotating gear rings 412 are arranged face to face in the first direction, and four rotating gears 413 are arranged between the two rotating gear rings 412. The four rotating gears 413 are evenly distributed in the rotating groove 411 around the first direction, and the four rotating gears 413 are arranged in a one-to-one correspondence with the four support plates 420. A threaded rod 414 is arranged on each rotating gear 413, and the threaded rod 414 is arranged along the second direction and spirally matched with the rotating gear 413. A cam 415 is arranged on the threaded rod 414, and a limiting groove is provided on the support plate 420. The limiting groove is a waist-shaped groove and passes through the side wall of the metal part 100 in the second direction. The cam 415 is located in the limiting groove and only abuts against the lower wall surface of the limiting groove, and when the support plate 420 moves along the second direction toward the side wall of the corresponding metal part 100, the cam 415 can always be located in the limiting groove, and the limiting groove can limit the cam 415 from rotating around the second direction.

[0052] By setting a rotating gear 413, a threaded rod 414 and a cam 415. When the support plate 420 moves along the second direction toward the side wall of the metal member 100 corresponding to it, the rotating block 410 will also rotate and drive the rotating gear 413 to rotate around the second direction through the rotating gear ring 412, that is, the rotating gear 413 rotates around its own axis. The rotation of the rotating gear 413 will cause the threaded rod 414 corresponding to it to move in the second direction, and drive the cam 415 to move synchronously, so that when the support plate 420 moves along the second direction toward the side wall of the metal member 100 corresponding to it, the cam 415 is always located in the limiting groove. That is, the cam 415 moves synchronously with the support plate 420. The cam 415 is used to limit the up and down movement of the upper plate 421, so that when the corrugated block 450 on the lower plate 422 moves up and down in coordination with the corrugated groove 210, the compression amount of the first elastic member 423 is increased, and the vibration amplitude of the upper plate 421 is reduced, thereby further avoiding the situation where the overall vibration amplitude of the support plate 420 is too large, which may cause the support plate 420 to not only fail to further fit with the side wall of the metal part 100, but also cause the metal part 100 to further deform due to the vibration of the support plate 420, and further avoid the phenomenon of misalignment between the punched hole and the clearance hole 424.

[0053] In this embodiment, the support mechanism 400 has a first state and a second state. When in the first state, the support plate 420 moves along the second direction and the rotating block 410 rotates around the first direction synchronously. When in the second state, after the rotating block 410 rotates around the first direction, the support plate 420 moves along the first direction.

[0054] When the support plate 420 is used to support the side wall of the metal member 100, the support mechanism 400 is placed in the first state. After the support is completed, punching begins, so that the output end of the punching mechanism 300 passes through the side wall of the metal member 100 and the clearance hole 424 in sequence along the second direction. At this time, the output end of the punching mechanism 300 is partially inserted into the support plate 420. At this time, the punching is completed, and the support mechanism 400 can be reset. The support mechanism 400 is switched to the second state, and the rotating block 410 is first rotated around the first direction, and the follower block 430 and the cam 415 are reset. Then, the support plate 420 is moved along the second direction toward the side wall of the corresponding metal part 100. Due to the loss of the restrictions of the cam 415 and the follower block 430, the resistance to the movement of the support plate 420 is reduced, and the overall vibration amplitude of the support plate 420 is increased, thereby driving the output end of the punching mechanism 300 in the yield hole 424 of the support plate 420 to vibrate. Since the output end of the punching mechanism 300 has not withdrawn from the side wall of the metal part 100 at this time, the passive vibration of the punch can remove the burrs on the side wall of the metal part 100 to a certain extent, thereby improving the quality of the punching.

[0055] In combination with the above embodiments, the specific working process is as follows:

[0056] When in use, after the metal part 100 is placed on the processing table 200 and sleeved on the support mechanism 400, the four hydraulic telescopic cylinders 440 are started to move the four support plates 420 along the second direction toward the side walls of the corresponding metal parts 100 until each support plate 420 abuts against the side walls of the corresponding metal parts 100.

[0057] At the same time, the motor is started to drive the rotating block 410 to rotate around the first direction. The rotating block 410 rotates around the first direction, driving the push block 416 to rotate, and the outer peripheral wall of the push block 416 pushes the sliding block to slide along the arc surface of the outer peripheral wall, so that the follower block 430 can slide in the movable groove 417, and then the follower block 430 can cooperate with the support plate 420 to extend out, and through the setting, when the sliding block slides to its corresponding outer point, the support plate 420 can abut against the side wall of the corresponding metal part 100, and the four follower blocks 430 can be respectively inserted between two support plates 420 adjacent to each other around the first direction.

[0058] And when the support plate 420 moves along the second direction toward the side wall of the corresponding metal part 100, the rotating block 410 will also rotate and drive the rotating gear 413 to rotate around the second direction through the rotating gear ring 412. The rotation of the rotating gear 413 will prompt the corresponding threaded rod 414 to move in the second direction and drive the cam 415 to move synchronously, so that when the support plate 420 moves along the second direction toward the side wall of the corresponding metal part 100, the cam 415 is always located in the limiting groove. The cam 415 is used to limit the up and down movement of the upper plate 421, so that when the corrugated block 450 on the lower plate 422 moves up and down in coordination with the corrugated groove 210, the compression amount of the first elastic member 423 is increased, and the vibration amplitude of the upper plate 421 is reduced, thereby further avoiding that if the overall vibration amplitude of the support plate 420 is too large, the support plate 420 may not only fail to further fit with the side wall of the metal part 100, but may also cause the metal part 100 to further deform due to the vibration of the support plate 420, and further avoid the phenomenon of the punched hole and the clearance hole 424 being misaligned. Afterwards, the four side walls of the metal part 100 can be punched at the same time by four punching mechanisms 300, thereby improving the punching efficiency.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
