Detailed implementation manners

[0024] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0026] As Figure 1 - Figure 8 shown, an automatic stamping die for a metal material includes an L-shaped workbench 1. A path groove 14 is provided on the surface of the L-shaped workbench 1. A connecting plate 5 is slidably mounted on the surface of the L-shaped workbench 1. A sliding column slidably mounted in the path groove 14 is provided at the bottom of the connecting plate 5. A fixing frame 6 is installed at the front end of the connecting plate 5 by bolts. A lower die 4 is fixedly installed at the front end of the fixing frame 6. A core block 16 is provided inside the lower die 4. A die core 26 is cooperatively installed above the core block 16. A supporting front plate 2 is fixedly provided at the front end of the L-shaped workbench 1. An upper die 3 is provided at the bottom of the supporting front plate 2. A second cylinder 38 is provided at the top of the supporting front plate 2. The output end of the second cylinder 38 is connected to the upper die 3. The upper die 3 cooperates with the lower die 4. A displacement mechanism 39 is provided on the side surface of the L-shaped workbench 1. The displacement mechanism 39 cooperates with the connecting plate 5. A side plate 31 is fixedly installed at the frontmost end of the L-shaped workbench 1. A guiding mechanism 36 is provided inside the side plate 31.

[0027] Inside the core block 16, a gear 22 is rotatably arranged. Below the gear 22, a frame plate 20 is provided. The frame plate 20 is movably sleeved in the middle of the gear 22. One end surface of the frame plate 20 is provided with a rack 21. The rack 21 meshes with the gear 22. Above and below the end of the gear 22, a first L-shaped bar 23 and a second L-shaped bar 24 are movably arranged respectively. The surfaces of the first L-shaped bar 23 and the second L-shaped bar 24 are both provided with rack surfaces that cooperate with the gear 22. At the tops of the two first L-shaped bars 23 and the two second L-shaped bars 24, clamping plates 25 are fixedly installed. And the two clamping plates 25 are symmetrically arranged on the top of the core block 16. Since both the first L-shaped bar 23 and the second L-shaped bar 24 cooperate with the gear 22 through the rack surfaces, when the frame plate 20 is lifted, under the cooperation of the rack 21 and the gear 22, the gear 22 rotates forward. At this time, the first L-shaped bar 23 and the second L-shaped bar 24 simultaneously displace towards both sides of the core block 16, and the distance between the two clamping plates 25 increases. When the frame plate 20 descends, under the cooperation of the rack 21 and the gear 22, the gear 22 rotates reversely. At this time, the first L-shaped bar 23 and the second L-shaped bar 24 simultaneously displace towards the center of the core block 16, and the distance between the two clamping plates 25 decreases. On the surface of the clamping plate 25, a convex block 29 is fixedly arranged. At the bottom of the die core 26, positioning blocks 27 are symmetrically installed. On the surface of the positioning block 27, a groove 28 corresponding to the convex block 29 is provided. The convex block 29 is fixedly installed in the groove 28. When the first L-shaped bar 23 and the second L-shaped bar 24 simultaneously displace towards the center of the core block 16, the convex block 29 can be clamped in the groove 28 to realize the fixation of the die core 26.

[0028] At the bottom of the frame plate 20, a long bar 18 is fixedly installed. The end of the long bar 18 protrudes from the lower die 4. The bottom surface of the end of the long bar 18 is arc-shaped. A support plate 19 is installed in the middle of the long bar 18. A return spring is arranged between the support plate 19 and the core block 16. On the surface of the L-shaped workbench 1 and symmetrically on both sides of the path groove 14, lifting blocks 15 are installed. The lifting blocks 15 correspond to the ends of the long bar 18. Through the cooperation of the end of the long bar 18 and the lifting blocks 15, when the whole lower die 4 moves to the other end of the path groove 14, the arc-shaped surface of the lifting block 15 has a lifting effect on the long bar 18. At this time, the whole long bar 18 displaces upward, and the frame plate 20 will also be lifted. And when the support plate 19 contacts the bottom of the core block 16, the long bar 18 continues to displace upward, and the support plate 19 can drive the whole core block 16 to displace upward, which further facilitates the staff to replace the die core 26.

[0029] On both sides of the long bar 18 at the bottom of the core block 16, tension springs 17 are provided. When the lower die 4 moves away from the lifting block 15, under the action of the tension springs 17, the position of the core block 16 descends, and the die core 26 can be fitted inside the lower die 4, with a good fixing effect on the die core 26 and improving the quality of workpiece stamping.

[0030] The displacement mechanism 39 includes a first cylinder 7. An active block 8 is installed at the output end of the first cylinder 7. A first rotating block 9 is rotatably arranged on the top of the active block 8. A second rotating block 10 is rotatably arranged on the top of the connecting plate 5. A light rod 11 is connected between the first rotating block 9 and the second rotating block 10. With the cooperation of the first rotating block 9, the second rotating block 10 and the light rod 11, when the first cylinder 7 drives the active block 8 to move forward, the light rod 11 can pull the connecting plate 5, so that the connecting plate 5 moves towards the other end of the path groove 14, so that the end of the strip 18 can contact the lifting block 15, causing the strip 18 to be lifted. By arranging the displacement mechanism 39 and the core block 16, the displacement mechanism 39 can drive the lower die 4 to move freely along the path of the path groove 14, and through the cooperation between the internal structure of the core block 16 and the lifting block 15, the replacement efficiency of the die core 26 by the staff can be greatly improved. At the same time, the operation environment during the replacement of the die core 26 is wider, improving the convenience and comfort of the operation.

[0031] A chute 12 is provided on the side surface of the L-shaped workbench 1. A slider 13 corresponding to the chute 12 is arranged on the surface of the active block 8. The slider 13 is slidably installed in the chute 12. With the cooperation of the slider 13 and the chute 12, the stability of the active block 8 during work can be effectively enhanced, and the operation efficiency of the device can be improved.

[0032] The guiding mechanism 36 includes a receiving cylinder 33. A receiving groove 32 is arranged inside the side plate 31. The receiving cylinder 33 is movably installed inside the receiving groove 32. A through groove 34 is arranged on one side of the receiving groove 32. A matching block 35 is fixedly arranged on the surface of the receiving cylinder 33. The matching block 35 is movably installed in the through groove 34. A trapezoidal block 30 is fixedly arranged at the front end of the lower die 4. An inclined surface is arranged on the upper surface of the trapezoidal block 30. A matching inclined surface is arranged at the bottom of the matching block 35. The trapezoidal block 30 is matched with the matching block 35. A guiding rod 37 is arranged on the side surface of the upper die 3. The surface of the guiding rod 37 is movably installed inside the receiving cylinder 33. When the lower die 4 is located directly below the upper die 3, the trapezoidal block 30 can be inserted into the through groove 34, and the inclined surface has an extrusion effect on the matching inclined surface, so that the position of the receiving cylinder 33 is lifted upward, so that the bottom of the guiding rod 37 can be inserted into the receiving cylinder 33. When the upper die 3 punches the lower die 4, the guiding rod 37 and the receiving cylinder 33 play a guiding role in the upper die 3 and the lower die 4, ensuring the punching quality of the upper die 3 and the lower die 4.

[0033] The horizontal height of the lifting block 15 is lower than the horizontal height of the light rod 11. When the displacement mechanism 39 works, the light rod 11 will swing. Since the horizontal height of the lifting block 15 is lower than the horizontal height of the light rod 11, the lifting block 15 will not affect the swing of the light rod 11.

[0034] Working principle: First, when the first cylinder 7 drives the movable block 8 to move forward, the optical rod 11 can pull the connecting plate 5, causing the connecting plate 5 to move towards the other end of the path groove 14, so that the end of the long strip 18 can contact the lifting block 15. Then, the arc surface on the surface of the lifting block 15 has a lifting effect on the long strip 18. At this time, the long strip 18 moves upward as a whole, and the frame plate 20 also rises. With the cooperation of the rack 21 and the gear 22, the gear 22 rotates forward. At this time, the first L-shaped strip 23 and the second L-shaped strip 24 move towards both sides of the core block 16 at the same time, and the distance between the two clamping plates 25 increases, and the convex block 29 disengages from the groove 28. Then, when the support plate 19 contacts the bottom of the core block 16, the long strip 18 continues to move upward, and the support plate 19 can drive the core block 16 to move upward as a whole, and the die core 26 disengages from the lower die 4, which facilitates the disassembly work of the die core 26 by the staff. Next, the first cylinder 7 drives the movable block 8 to move backward. At this time, driven by the optical rod 11, the lower die 4 moves to directly below the upper die 3. Since the long strip 18 is far from the lifting block 15, under the action of the tension spring 17, the position of the core block 16 drops. At the same time, under the action of the return spring, the support plate 19 drives the position of the frame plate 20 to drop. With the cooperation of the rack 21 and the gear 22, the gear 22 rotates in the reverse direction. At this time, the first L-shaped strip 23 and the second L-shaped strip 24 move towards the center of the core block 16 at the same time, and the distance between the two clamping plates 25 decreases, and the convex block 29 can be clamped in the groove 28 to fix the die core 26, and the die core 26 can be embedded into the lower die 4 to ensure the stamping quality of the upper die 3 and the lower die 4.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
