Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, and in particular to a stamping device which is convenient for workpiece stripping. Background Art

[0002] Stamping machines are important equipment widely used in the manufacturing industry, especially in the fields of automobile manufacturing and home appliance production. The stamping process is to change the shape of the workpiece by moving the mold on the stamping equipment toward the plate and applying pressure to the plate, thereby achieving precise forming of the workpiece. However, in traditional stamping production, the workpiece often remains adhered to the plate after stamping. In this case, workers are often required to peel or remove these stamped workpieces from the plate, which not only increases the complexity of the production process, but also increases labor costs. In particular, when a batch of workpieces need to be stamped multiple times on a plate, it is necessary to wait until the stamping operation of the entire plate is completed before the peeling operation can be performed. In the process of the entire plate moving toward the stamping machine, these adhered workpieces will also cause the plate to appear uneven, affecting subsequent stamping operations. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a stamping device that facilitates workpiece removal, which solves the problem in the prior art that the workpiece formed after the stamping equipment performs a stamping operation on the plate adheres to the plate and affects subsequent processes.

A push rod is provided at the bottom of each connecting block.

[0005] Compared with the prior art, the present invention has the following beneficial effects: by adopting the first conveyor belt to transport the plate, after the plate enters under the stamping machine body, the stamping machine body performs stamping operation on the plate, during the stamping operation, the fixing component will first fix the plate to prevent the plate from moving so as to obtain better stamping quality, each stamping of the stamping machine body will drive the push rod to move downward, and each downward movement of the push rod will push the workpiece formed by the previous stamping operation from the plate to the blanking chute, on the one hand, it avoids the formed workpiece remaining on the plate causing the plate to be uneven and affect the movement of the plate, on the other hand, it quickly pushes the workpiece off the plate to be collected in the blanking chute, saving labor costs.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1—4, as shown, an embodiment of the present invention proposes a stamping device that is convenient for workpiece stripping, including a side panel 1, a supporting platform 5 and a stamping machine body 7. The side panel 1 is divided into two pieces. A first conveyor belt 2 and a second conveyor belt 3 are arranged between the two side panels 1. A baffle 4 is arranged on the first conveyor belt 2. The supporting platform 5 is arranged between the first conveyor belt 2 and the second conveyor belt 3. A blanking trough 6 is opened through the top of the supporting platform 5. The blanking trough 6 is inclined. The stamping machine body 7 is erected between the two side panels 1 through support columns and is located directly above the supporting platform 5. Fixed components are symmetrically arranged on both side walls of the stamping machine body 7. The fixed components are used to fix the plate conveyed to the supporting platform 5. A mounting block 8 is fixedly arranged on the side of the stamping machine body 7 facing the second conveyor belt 3. A plurality of connecting blocks 9 are detachably provided on the mounting block 8. A push rod 10 is provided at the bottom of each connecting block 9. When stamping the plate, the plate to be stamped is placed at the center position of the first conveyor belt 2. If necessary, a limit plate can be set to facilitate the centering operation of the plate. The first conveyor belt 2 and the second conveyor belt 3 mainly play the role of conveying the plate, and both are conventional structures. No further details are given here. The baffle 4 arranged on the first conveyor belt 2 can facilitate the pushing of the plate toward the direction of the second conveyor belt 3. After the first conveyor belt 2 conveys one end of the plate to the supporting platform 5, the first conveyor belt 2 temporarily stops the conveying operation, and the punching machine body 7 is started. A punching die is provided at the bottom of the punching machine body 7. The punching machine moves downward under the action of its power mechanism to perform a punching operation on the plate. When the punching machine body 7 is stamping, the fixing component fixes the plate on the supporting platform 5 to prevent it from moving. After completing a stamping operation, the first conveyor belt 2 is started to continue to convey the plate for a distance. At this time, the punching machine body 7 moves downward again for stamping operation. At this time, the workpiece punched by the previous stamping operation is in the blanking trough 6. Directly above, when the mounting block 8 moves downward with the punching machine body 7, the push rod 10 on the connecting block 9 hits the position on the plate that has been punched by the punching machine body 7. These workpieces adhered to the plate are separated from the plate and fall into the blanking chute 6 under the impact of the push rod 10, and then fall out from one side of the carrier 5 through the blanking chute 6. The worker can place a collection frame at the outlet of the blanking chute 6 to collect these workpieces. After the entire plate is punched, the remaining plate waste is transported to another collection place by the second conveyor belt 3. In principle, since the push rod 10 of the device moves with the mounting block 8, each time the punching machine body 7 punches the plate, the push rod 10 will hit the workpiece punched and formed in the previous punching operation, so that this part of the workpiece adhered to the plate will be detached from the plate and fall into the blanking chute 6 to be collected, thereby avoiding the workpiece adhered to the plate from affecting the overall movement of the plate, and also avoiding the plate from being uneven, thereby ensuring the quality of the workpiece formed after the subsequent punching machine body 7 punches the plate.

[0022] like Figure 4As shown in FIG. 5 , further, a slide groove is provided on the mounting block 8, and a slider 11 corresponding to the connecting block 9 is slidably provided in the slide groove, and a screw rod 12 is fixedly provided on one side of each slider 11, and a through hole for the screw rod 12 to pass through is provided on each connecting block 9, and a nut 13 is threadedly connected on each screw rod 12. Specifically, in this embodiment, the slide groove is a T-shaped groove, and the slider 11 can slide arbitrarily in the slide groove, so as to adjust the position of the slider 11 and the connecting block 9. When the connecting block 9 is fixed to the mounting block 8, the slider 11 is slid to a predetermined position, and then the connecting block 9 is penetrated on the screw rod 12 through the through hole, and then the nut 13 is screwed, so as to lock the connecting block 9 on the mounting block 8, so as to adjust the position of the connecting block 9 and disassemble the connecting block 9, and to facilitate the number of workpieces formed by different stamping operations. Preferably, the length of the screw rod 12 is set as required, and the spacing between the connecting block 9 and the mounting block 8 can be adjusted by screwing the nut 13 between the mounting block 8 and the connecting block 9, so as to change the position of the push rod 10.

[0023] like Figure 6 As shown, further, each connection block 9 is provided with an extension block 14 on one side facing the mounting block 8, and the extension block 14 extends into the slide slot. Specifically, the height of the extension block 14 is the same as the width of the slide slot, so that the two can slide closely together, so that when the nut 13 is screwed to lock the connection block 9 and the mounting block 8, the inner wall of the slide slot will limit the extension block 14, thereby limiting the relative rotation of the connection block 9 and the mounting block 8, thereby preventing the push rod 10 at the bottom of the connection block 9 from being skewed, avoiding deviation in the position of the subsequent push rod 10 hitting the workpiece, and ensuring the push rod 10 to separate the workpiece.

[0024] like Figure 5 As shown, further, a mounting groove is provided at the bottom of each connection block 9, and each push rod 10 is slidably arranged in the corresponding mounting groove. One end of a first spring 15 is fixedly arranged on the inner wall of each mounting groove, and the other end of the first spring 15 is fixedly connected to the push rod 10. When the push rod 10 follows the connection block 9 and the punch body 7 to move downward, it hits the plate. In order to avoid deviation, the push rod 10 hits the position on the plate where the workpiece is not formed, resulting in a rigid collision, causing the plate to deform or the reverse impact force to cause the connection part between the connection block 9 and the mounting block 8 to deform. By setting the first spring 15, the first spring 15 plays a buffering role on the reverse impact force received by the push rod 10, thereby preventing the push rod 10 from transmitting force to other components after being subjected to a rigid collision, resulting in damage to the components. In this embodiment, the first spring 15 is preferably a spring with a large elastic coefficient, so that the push rod 10 is sufficient to push down the workpiece adhered to the plate.

[0025] like Figure 5 and 6As shown, further, a cutter 16 is provided at the bottom of the mounting block 8. The cutter 16 is arranged at the bottom of the mounting block 8, and the cutter 16 can move with the mounting block 8. When the punching machine body 7 moves toward the plate to perform the punching operation, since the mounting block 8 is located on the side of the punching machine body 7 facing the second conveyor belt 3, the cutter 16 moves downward to cut the plate. In this embodiment, the width of the blanking trough 6 is smaller than the width of the plate, so that a part of the plate cut off by the cutter 16 will not fall into the blanking trough 6, but will be subsequently pushed onto the second conveyor belt 3 and transported away, thereby avoiding the bending and deformation of a large amount of waste connected to the plate to affect the movement of the plate, and also realizing the classified collection of the plate and the waste.

[0026] like Figure 6 As shown, further, each fixing assembly includes: a fixing block 17, both sides of the punching machine body 7 are fixedly provided with the fixing block 17, the bottom of each fixing block 17 is detachably provided with a fixing cylinder 18, abutting columns 19 are slidably provided in the fixing cylinder 18, one end of a second spring 20 is also fixedly connected in the fixing cylinder 18, and the other end of the second spring 20 is fixedly connected to the abutting columns 19. The fixing block 17 moves with the punching machine body 7. When the punching machine body 7 moves downward to punch the plate, the fixing block 17, the fixing column and the abutting columns 19 also move downward. Before the mold at the bottom of the punching machine body 7 contacts the plate, the abutting columns 19 will first press the plate at the upper limit value to move the plate. The second spring 20 allows the abutting columns 19 to be buffered when they abut on the plate to avoid rigid friction, and also allows the abutting columns 19 to abut against the plate more stably and tightly.

[0027] Furthermore, a thread groove is provided at the bottom of each fixing block 17, and an external thread is provided on the outer wall of the fixing cylinder 18, and the fixing cylinder 18 is threadedly connected to the fixing block 17. By threading the fixing cylinder 18 and the fixing block 17, the relative distance between the bottom end of the abutment column 19 and the fixing block 17 can be adjusted, so that plates of different thicknesses can be fixed and pressed, and a better pressing effect can be applied to the plates by finely adjusting the distance between the abutment column 19 and the fixing block 17.

[0028] like Figure 5 and 6 As shown, further, a rubber sleeve 21 is included, and an annular groove is formed on the outer wall of the abutment column 19, and the rubber sleeve 21 is sleeved on the bottom of the abutment column 19 through the annular groove. Specifically, the rubber sleeve 21 is a concave structure, and by sleeved on the bottom of the abutment column 19, the friction and the clamping force between the abutment column 19 and the plate are increased, thereby better limiting the displacement of the plate when the punching machine body 7 is punched.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
