[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Example 1

[0029] Reference Figure 1-4A mechanical stamping device includes a base 1, a main body 2, a hydraulic rod 3, a punch 4, and a die 5. The main body 2 is fixed to the top of the base 1, and the hydraulic rod 3 is fixed to the top of the inner side of the main body 2. The punch 4 is assembled at the output end of the hydraulic rod 3. The die 5, corresponding to the position of the punch 4, is placed on the top of the base 1 and at a position offset from the main body 2. A quick-change mechanism is assembled between the hydraulic rod 3 and the punch 4 for quickly changing the punch 4.

[0030] The quick-change mechanism includes a connecting block 6, a clamping block 7, a locking block 8, and a first groove 9. The output end of the hydraulic rod 3 is fixed with the connecting block 6. Two clamping blocks 7 are slidably connected to the bottom of the connecting block 6. The connecting block 6 and the clamping blocks 7 are slidably connected through a guide rail to ensure a stable connection between the two. A locking block 8 is slidably connected to the top of the two clamping blocks 7. The bottom of each clamping block 7 is provided with a first groove 9, and the inner side of the first groove 9 is engaged with the punch 4.

[0031] The quick-change mechanism also includes a second groove 10, a pin 11 and a pin hole 12. The second groove 10 is provided on one side of the locking block 8, and a pin hole 12 is provided on one side of one of the clamping blocks 7. A pin 11 is slidably connected between the pin hole 12 and the second groove 10.

[0032] Example 2

[0033] Further optimizations to Example 1, specifically, such as... Figure 4 As shown, a limiting mechanism is assembled between the pin 11 and the pin hole 12. The limiting mechanism is used to limit the pin 11. The locking block 8 has a mark engraved on one side of the second groove 10. The pin 11 is also set with a corresponding mark to determine whether the limiting mechanism is effective, so that the operator can observe it.

[0034] The limiting mechanism includes a third groove 13, a locking block 14, a fourth groove 15, and a spring 16. The third groove 13 is provided on the outer side of the pin 11. The locking block 14 is rotatably connected to the bottom of the inner side of the third groove 13. The fourth groove 15, corresponding to the position of the locking block 14, is provided on the inner side of the pin hole 12. The fourth groove 15 is slidably connected to the locking block 14. The spring 16 is fixed to one end of the inner side of the pin hole 12. The spring 16 is clearance-fitted with the pin hole 12. The mutual cooperation between the pin 11 and the pin hole 12, as well as the limiting mechanism, further enhance the connection rigidity and prevent the punch from loosening or shifting during the stamping process.

[0035] Example 3

[0036] Further optimizations to Example 1, specifically, such as... Figure 5-6 As shown, a positioning mechanism is assembled between the base 1 and the die 5, which is used to position the die 5.

[0037] The positioning mechanism includes a slot 17, a clamp housing 18, a cylinder 19, a push block 20, a moving block 21, a pressure plate 22, and a dovetail guide rail 23. A slot 17 is formed between the base 1 and the main body 2. The clamp housing 18 is fixed to the inside of the slot 17. The cylinder 19 is fixed to one side of the clamp housing 18. The output end of the cylinder 19 passes through the clamp housing 18 and is fixed to the push block 20. The moving blocks 21 are slidably connected to both ends of the push block 20. The moving blocks 21 slide against the inside of the clamp housing 18. The movable block 21 is connected to a pressure plate 22 at one end. The two pressure plates 22 are provided with anti-slip texture on the side that is close to each other. The pressure plate 22 is driven by the cylinder 19 to clamp the die 5. At the same time, the anti-slip texture increases the friction to ensure that the die 5 is reliably fixed during the stamping process. The top of the base 1 and the position corresponding to the die 5 are provided with a dovetail guide rail 23. The dovetail guide rail 23 is slidably connected to the bottom of the die 5. The design of the dovetail guide rail 23 allows the die 5 to slide along the guide rail, realizing quick loading and unloading.

[0038] In summary:

[0039] This utility model addresses the technical problem that existing technologies lack a system design for rapid replacement of dies and punches. Some existing quick-change structures are only designed for a single die type and suffer from unreliable locking and poor adaptability, making it difficult to meet the rapid switching requirements of dies of different sizes and specifications. The present invention adopts the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows: When it is necessary to replace the punch 4, the operator first rotates the pin 11, and the locking block 14 on the pin 11 retracts into the third groove 13, releasing the pin 11 from the limiting lock on the locking block 8 and the clamping block 7. Then, the pin 11 is pulled out from the limiting channel formed by the pin hole 12 and the second groove 10. At this time, the locking block 8 is pulled upwards, and the clamping block 7 can move freely along the guide rail at the bottom of the connecting block 6, allowing the first groove 9 to disengage from the punch 4, easily removing the old punch 4. When installing the new punch 4, the clamping block 7 is pushed to slide towards the guide rail, allowing the clamping block 7 to tightly clamp the new punch. The punch 4 is then put back into the locking block 8 and the clamping block 7. At this time, the pin 11 enters the pin hole 12 through the second groove 10. The spring 16 set inside the pin hole 12 abuts the pin 11. Rotating the pin 11 causes the locking block 14 to engage with the fourth groove 15, forming a mechanical locking structure, thus completing the quick replacement and stable installation of the punch 4. When the die 5 needs to be replaced, the cylinder 19 drives the push block 20. The guide rails on both sides of the push block 20 will cause the moving block 21 and the pressure plate 22 set on the moving block 21 to move in opposite directions, thereby releasing enough space to allow the die 5 to move along the dovetail guide rail 23 set on the base 1, which is convenient for replacing the die 5.

[0040] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0041] 1. Through the structural design of the quick-change mechanism, the operator does not need to disassemble the bolts. He only needs to pull out the pin 11 and slide the locking block 8 to complete the disassembly of the punch 4. The pin 11 and pin hole 12 set on the quick-change mechanism cooperate with each other and the limiting mechanism further enhances the connection rigidity, prevents the punch from loosening or shifting during the stamping process, improves the replacement efficiency, and ensures the consistency of the dimensional accuracy of the stamped parts.

[0042] 2. Through the structural design of the positioning mechanism, the positioning mechanism drives the pressure plate 22 to clamp the die 5 through the cylinder 19. The anti-slip texture increases the friction and ensures that the die 5 is reliably fixed during the stamping process. The design of the dovetail guide rail 23 allows the die 5 to slide along the guide rail, realizing quick loading and unloading, which is beneficial to use.
