[0030] Example:

[0031] The present application embodiment discloses a punching device for a plate-shaped fastener, see Figure 1 , Figure 2 and Figure 3 The platform 1 comprises a table 1, the four corners of the bottom of the table 1 are fixedly connected with legs, and a through slot 2 is provided at the center of the table 1, a buffer plate 3 is slidably sleeved on the inner wall of the upper side of the through slot 2, a supporting plate 4 is provided directly below the buffer plate 3, and four fixing rods 5 are evenly fixedly connected to the outer circumference of the top of the supporting plate 4, the four fixing rods 5 are all located on the outside of the bottom end of the through slot 2, and the four fixing rods 5 are fixedly installed at the bottom of the table 1, and a spring 6 is fixedly installed at the connection between the buffer plate 3 and the supporting plate 4, and the inner side of the spring 6 A limit expansion joint 7 is provided at the position, and the limit expansion joint 7 is located at the center between the buffer plate 3 and the supporting plate 4. Four limit brackets 8 are evenly fixedly installed on the outer circumference of the bottom of the buffer plate 3. The four limit brackets 8 are all "L"-shaped block structures, and the inner side walls of the bottom ends of the four limit brackets 8 are in conflict with the bottom of the table 1, and the four limit brackets 8 and the four fixed rods 5 are staggered. Clamping components are symmetrically arranged on both sides of the top of the table 1, and a punching component is arranged on one side between the two groups of clamping components;

[0032] The position-limiting expansion joint 7 comprises a group of round rods and cylinders which are arranged in a sliding sleeve manner, and the ends of the round rods and the cylinders which are away from each other are fixedly connected to the center positions of the end surfaces of the supporting plate 4 and the buffer plate 3 respectively.

[0033] See also Figure 1 and Figure 4 The clamping assembly includes a moving plate 9, a multi-section electric push rod 10 is fixedly installed at the center of the moving plate 9 through a first mounting sleeve, a clamping plate 11 is fixedly installed at the driving end of one side of the multi-section electric push rod 10, and the clamping plate 11 is located on one side of the moving plate 9 in the horizontal direction;

[0034] The clamping assembly also includes a slide groove 12 opened on both sides of the bottom end of the movable plate 9, and the inner wall of the slide groove 12 is slidably sleeved with a slide ball 13, and the bottom end of the slide ball 13 extends out of the interior of the slide groove 12 and slides in contact with the top of the table 1. Each set of slide grooves 12 and slide balls 13 set at the bottom end of the movable plate 9 can effectively reduce the wear problem between the two under the support and sliding action of the movable plate 9 on the top of the table 1, and the opposite end surfaces of the two clamping plates 11 are fixedly connected with anti-slip rubber sheets, which are used to effectively prevent the fasteners from slipping and deflecting during the clamping process.

[0035] See also Figure 1 and Figure 2 The punching assembly includes an L-shaped frame 14 fixedly mounted on the middle of one side of the top of the table 1, a punching cylinder 15 is fixedly mounted on one side of the top of the L-shaped frame 14 through a second mounting sleeve, a connecting block 16 is fixedly mounted on the driving end of the bottom of the punching cylinder 15, a punching head 17 is fixedly mounted at the center position of the bottom of the connecting block 16, and the punching head 17 is located above the center position of the buffer plate 3;

[0036] The inner cavity at the bottom end of the L-shaped frame 14 is horizontally penetrated and fixedly sleeved with a slide bar 18, and the two sides of the slide bar 18 are respectively penetrated and slidably sleeved in the inner cavity on the same side of the two movable plates 9, and the tops of the other sides of the two movable plates 9 are fixedly connected with a lifting link 20, and the tops of the two lifting links 20 are commonly fixedly connected with a horizontal bar 19, which is located above one side of the table 1, and a handle is fixedly installed at the center of the top of the horizontal bar 19. The lifting effect of the two lifting links 20 on the horizontal bar 19 can facilitate the extraction and push-type pick-and-place operation of the processed fasteners on the top of the table 1;

[0037] Among them, a control panel is fixedly installed on the front side of the top of the L-shaped frame 14. The control panel is electrically connected and controlled with the multi-section electric push rod 10 and the punching cylinder 15 through wires. The connection and control of the two by the control panel can be achieved through programming, which is a prior art and will not be described in detail here.

[0038] The implementation principle of this embodiment is as follows: when in use, the whole is in a complete assembly state, the plate-shaped fastener to be processed is placed on the top of the table 1, and the two multi-section electric push rods 10 are used to horizontally drive the clamping plate 11 to achieve the clamping effect on both ends of the fastener, and during the overall fastener punching process, the top handle of the horizontal bar 19 is kept in the state of being manually held;

[0039] The horizontal driving force of the horizontal bar 19 by the hand-held handle indirectly causes the positioned fastener and the two sets of clamping components to move horizontally on the top of the table 1 (in this process, one end of the two moving plates 9 is horizontally limited and slidably matched on the outer wall of the slide bar 18), thereby adjusting the horizontal punching position of the fastener under the punching head 17. The vertical punching position of the fastener under the punching head 17 can also be adjusted by clamping and slightly loosening the fastener with the two clamping plates 11;

[0040] When the punching cylinder 15 is started to drive downward, the punching head 17 can be used to effectively punch the fastener. After the punching head 17 penetrates the punching position of the fastener, due to the difference in thickness of different fasteners and the difference in the downward feeding height of the punching head 17 by the punching cylinder 15 and the thickness of the fastener, the punching head 17 will pressurize the buffer plate 3 after penetrating the fastener. At this time, the buffer plate 3 can passively move downward on the inner wall of the through groove 2 under the vertical limiting buffering action of the spring 6 and the limiting expansion joint 7, thereby avoiding direct stamping damage to the top of the table 1. When the punching head 17 moves up and resets, the buffer plate 3 can also be reset to its initial state inside the upper side of the through groove 2 through the reset of the spring 6 and the limiting action of each limiting bracket 8.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
