Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an automatic chamfering stamping die for hexagonal nuts. Background Technology

[0002] In the field of stamping die technology, the chamfering of hexagonal nuts is a key process to ensure their assembly performance and safe use.

[0003] The existing stamping and demolding processes of molds are not sufficiently automated. Either manual assistance is required to complete the stamping action, or the demolding process is cumbersome, requiring manual removal of the processed nuts from the mold. This not only increases the labor intensity of workers and reduces production efficiency, but also poses significant safety hazards. Therefore, we propose an automatic chamfering stamping mold for hexagonal nuts to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an automatic chamfering stamping die for hexagonal nuts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic chamfering stamping die for hexagonal nuts includes: a base; two sets of side plates are fixedly mounted on the top of the base; a top plate is fixedly mounted on the top of the two sets of side plates; a cylinder is fixedly mounted on the top of the top plate; a stamping block is fixedly mounted on the output end of the cylinder; a mounting seat is abutted against the top of the base; a lower die seat is fixedly mounted on the top of the mounting seat; a connecting rod and a circular plate are slidably mounted inside the lower die seat; the circular plate is fixedly mounted on the bottom of the connecting rod; a top block is fixedly mounted on the top of the connecting rod; and a return spring is fixedly mounted on the bottom of the circular plate. Four sets of round rods and a return spring are fixedly installed on the top of the mounting base. An upper mold base is slidably installed on the outer side of the four sets of round rods. A stamping die and two sets of limiting rods are fixedly installed on the bottom of the upper mold base. Two sets of limiting grooves are opened on the top of the lower mold base. Two sets of moving plates are slidably installed inside the top of the base. A connecting seat is fixedly installed on the top of each of the two sets of moving plates. An anti-slip clamp is fixedly installed on one side of each of the two sets of connecting seats. The two sides of the lower mold base abut against the adjacent side of the two sets of anti-slip clamps. The bottom of the stamping die and the inside of the lower mold base are both provided with chamfers.

[0007] Preferably, a drive motor is fixedly installed on one side of the base, a bidirectional lead screw is fixedly installed on the output end of the drive motor, two sets of moving plates are threadedly connected to the outside of the bidirectional lead screw, two sets of guide rods are slidably installed inside the top plate, the bottom of the two sets of guide rods are fixedly installed on the top of the stamping block, and four sets of support legs are fixedly installed at the bottom of the base.

[0008] Preferably, the top of the four sets of reset springs is fixedly installed at the bottom of the upper mold base, and the four sets of reset springs are set on the outer side of the corresponding round rod.

[0009] Preferably, the two sets of limiting rods are adapted to the corresponding limiting grooves, the stamping die is adapted to the lower die base, the lower die base has a slot and a guide groove inside, the top block is adapted to the slot, the circular plate is slidably installed in the guide groove, and the bottom of the second reset spring is fixedly installed on one side of the slot.

[0010] Preferably, the top of the base is provided with a guide rail, and the two sets of movable plates are slidably installed in the guide rail.

[0011] Preferably, the bidirectional lead screw is rotatably mounted inside the base.

[0012] In this utility model, an automatic chamfering stamping die for hexagonal nuts is provided. A drive motor drives a bidirectional lead screw to rotate. Since two sets of moving plates are threaded to the outside of the bidirectional lead screw, the rotation of the bidirectional lead screw causes the two sets of moving plates to slide towards each other in the guide rail at the top of the base. This, in turn, drives the connecting seat and the anti-slip clamping plate to move. The anti-slip clamping plate clamps the lower die seat, thus fixing the lower die seat. During the stamping process, this effectively prevents the lower die seat from shifting or shaking, ensuring the stability of the die during operation. This, in turn, ensures the accuracy of the chamfering of the hexagonal nuts and avoids problems such as dimensional deviations and poor surface quality of the nut chamfering caused by the loosening of the lower die seat.

[0013] This utility model has a reasonable structural design. A cylinder drives the stamping block to move downwards under the constraint of the guide rod and the top plate. The stamping block drives the upper die base and the stamping die downwards under the guidance of the round rod. The return spring contracts, and simultaneously, the limiting rod slides within the limiting groove, further ensuring accurate alignment between the stamping die and the lower die base. The stamping die and the lower die base cooperate, and the stamped part abuts against the top block, causing the top block to drive the connecting rod and the round plate downwards under the constraint of the guide groove. The top block then enters the groove. Because the bottom of the stamping die and the interior of the lower die base are chamfered, automatic chamfering of the hexagonal nut is achieved during the stamping process. After stamping is completed, the cylinder drives the stamping block to rise. The upper die holder drives the stamping die to return to its original position under the elastic force of the return spring one and the guidance of the round rod. At this time, the return spring two at the bottom of the round plate pushes the round plate in the guide groove, driving the connecting rod and the top block to move upward, pushing the machined hexagonal nut out of the lower die holder, completing the automatic demolding. This precise positioning can improve product quality and consistency, reduce the scrap rate caused by positioning deviation, and simplify the operation steps of the automated stamping and demolding process. Operators only need to load materials and monitor the equipment operation status, reducing the difficulty of operation and labor intensity. At the same time, it reduces the direct participation of humans in the stamping and demolding process, effectively avoiding the safety risks that may occur during manual operation.

An anti-slip clamp 21 is fixedly installed on one side of each of the two sets of connecting seats 20. The two sides of the lower mold base 5 abut against the adjacent side of the two sets of anti-slip clamps 21. The bottom of the stamping die 9 and the inside of the lower mold base 5 are both chamfered.

[0020] In this embodiment, a drive motor 3 is fixedly installed on one side of the base 1, and a bidirectional lead screw 18 is fixedly installed on the output end of the drive motor 3. Two sets of moving plates 19 are threadedly connected to the outside of the bidirectional lead screw 18. Two sets of guide rods 25 are slidably installed inside the top plate 23. The bottom of the two sets of guide rods 25 is fixedly installed on the top of the stamping block 26. Four sets of support legs 2 are fixedly installed at the bottom of the base 1 to ensure that the lower die base 5 does not shift during the stamping process, thereby improving the accuracy and consistency of the nut chamfer and reducing the scrap rate.

[0021] In this embodiment, the top of the four sets of reset springs 7 is fixedly installed at the bottom of the upper mold base 8, and the four sets of reset springs 7 are sleeved on the outer side of the corresponding round rod 6, which reduces the reset time and improves production efficiency.

[0022] In this embodiment, the two sets of limiting rods 10 are adapted to the corresponding limiting grooves 11, the stamping die 9 is adapted to the lower die base 5, the lower die base 5 has a slot 13 and a guide groove 16 inside, the top block 12 is adapted to the slot 13, the circular plate 15 is slidably installed in the guide groove 16, and the bottom of the reset spring 17 is fixedly installed on one side of the slot 13 to reduce shaking and vibration during stamping and improve processing quality.

[0023] In this embodiment, a guide rail is provided on the top of the base 1, and two sets of movable plates 19 are slidably installed in the guide rail, which enhances the adaptability of the mold to diverse production needs and improves the versatility of the mold.

[0024] In this embodiment, the bidirectional lead screw 18 is rotatably installed inside the base 1, which can ensure that the moving plate 19 reaches the predetermined position smoothly and accurately.

[0025] In this embodiment, during use, the drive motor 3 is started to drive the bidirectional lead screw 18 to rotate. Since the two sets of moving plates 19 are threadedly connected to the outside of the bidirectional lead screw 18, the rotation of the bidirectional lead screw 18 causes the two sets of moving plates 19 to slide towards each other in the guide rail at the top of the base 1, thereby driving the connecting seat 20 and the anti-slip clamp 21 to move.

The stamping die 9 and the lower die base 5 cooperate, and the stamped part abuts against the top block 12, causing the top block 12 to drive the connecting rod 14 and the round plate 15 downward under the constraint of the guide groove 16. The top block 12 moves into the slot 13. Since the bottom of the stamping die 9 and the interior of the lower die base 5 are both chamfered, the hexagonal nut is automatically chamfered during the stamping process. After the stamping is completed, the cylinder 24 drives the stamping block 26 to rise. The upper die base 8 drives the stamping die 9 to return to its original position under the elastic force of the return spring 7 and the guide of the round rod 6. At this time, the return spring 17 at the bottom of the round plate 15 pushes the round plate 15 to move the connecting rod 14 and the top block 12 upward in the guide groove 16, pushing the processed hexagonal nut out of the lower die base 5 and completing the automatic demolding.
