The fixed end of the second driving motor 4263 is connected to the connecting block 424, and the output shaft is connected to the second transmission tooth 4262.

[0072] The second driving motor 4263 drives the second transmission tooth 4262 to mesh with the rack 4261 , so that the slide bar 425 can slide relative to the slide groove.

[0073] Furthermore, the rack 4261, the second transmission gear 4262 and the second drive motor 4263 are all common and easily purchased devices on the market. They are conventional settings well known to those skilled in the art and will not be described in detail.

[0074] Among them, the bracket 411 is connected to the sliding bar 425, the negative pressure suction cup 412 is arranged relative to the fixed part 31, the third driving part 413 has a fixed end and an extended end, and the fixed end of the third driving part 413 is connected to the bracket 411, and the extended end is connected to the negative pressure suction cup 412.

[0075] The driving force generated by the third driving part 413 can realize the lifting and lowering of the negative pressure suction cup 412 relative to the fixing part 31, thereby improving the stability of the negative pressure suction cup 412 in clamping the material.

[0076] Furthermore, the negative pressure suction cup 412 here is a common and easy-to-purchase device on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0077] As an implementation method, Figure 4 As shown, there are four negative pressure suction cups 412 in the suction cup member 41 , and the connecting plate 414 is connected to the extended end of the third driving portion 413 and can slide relative to the bracket 411 , and the four negative pressure suction cups 412 are evenly arranged and connected to the connecting plate 414 .

[0078] By providing the connecting plate 414 , the four negative pressure suction cups 412 can all be raised and lowered relative to the bracket 411 , thereby improving the stability of material clamping.

[0080] The sliding fit between the guide hole and the guide rod 415 serves to connect and guide the sliding of the connecting plate 414 relative to the bracket 411 .

[0081] The specific working process of the utility model is as follows: the upper mold body 2 is arranged relative to the lower mold body 1, and can slide close to or away from the lower mold body 1, the fixed part 31 is connected to the lower mold body 1, and is used for clamping and holding the material, the punch rod 32 is arranged relative to the fixed part 31, and is connected to the upper mold body 2, the punch rod 32 can punch the material after the upper mold body 2 moves, the suction cup member 41 is arranged relative to the fixed part 31, the driving member 42 is connected to both the lower mold body 1 and the suction cup member 41, and the driving member 42 can drive the suction cup member 41 to slide close to or away from the fixed part 31, so that the suction cup member 41 after moving can clamp or release the material. Compared with the prior art, by setting the suction cup member 41 relative to the fixed part 31, under the drive of the driving member 42, the suction cup member 41 can slide relative to the material on the fixed part 31, and achieve the clamping or release of the material, thereby replacing the worker manually removing the material from the fixed part 31 after each punching.

[0082] During use, the user places the material on the fixed seat to complete the stamping process, and then the upper mold body 2 rises. First, the first driving motor 4233 is driven to move, and the rotating shaft 422, the connecting block 424 and the bracket 411 are driven to rotate close to the fixed seat, so that the bracket 411 and the negative pressure suction cup 412 are rotated to face the material. Then the second driving motor 4263 is driven, and the slide bar 425 is driven to slide relative to the connecting block 424. After sliding, the slide bar 425 drives the bracket 411 and the negative pressure suction cup 412 to slide to the top of the material, and then the third driving part 413 is driven to make the negative pressure suction cup 412 extend close to the material. After extending, the negative pressure suction cup 412 abuts against the material. Finally, the negative pressure suction cup 412 generates a negative pressure adsorption force to clamp the material.

[0083] Furthermore, when releasing the material, the third driving part 413 is first driven to retract the negative pressure suction cup 412 holding the material and remove the material from the fixed seat, and then the first driving motor 4233 is driven to drive the slide bar 425 to slide relative to the connecting block 424, and the negative pressure suction cup 412 holding the material slides away from the fixed seat, and then the first driving motor 4233 is driven to drive the rotating shaft 422 and the negative pressure suction cup 412 holding the material to rotate away from the fixed seat until the negative pressure suction cup 412 transfers the material to the designated area, and finally the adsorption force generated by the negative pressure suction cup 412 is removed, and the material automatically falls and is collected.

[0084] The device, through the above structure, can solve the technical problem in the prior art that the workpiece needs to be removed from the die manually after each stamping, which results in high workload for the workers and potential safety hazards.
