The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0049] See also Figure 1-8 , the present invention provides a technical solution:

[0050] The clamping device for stamping parts includes a workbench 101 and a punch assembly 102. The bottom end of the punch assembly 102 is detachably connected to a punch 103. The workbench 101 is provided with a clearance hole 14 that can cooperate with the punch 103. The workbench 101 is provided with a support base 11, and the support base 11 is provided with two sets of symmetrically arranged clamping assemblies.

[0051] The clamping assembly includes a fixed block 403 mounted on the support base 11, and the fixed block 403 is provided with at least two clamping elastic rods movably left and right, and the inner ends of the at least two clamping elastic rods are commonly connected to the same clamping frame, and the clamping frame is connected to the linkage block 20, and the top end surface 2001 of the linkage block 20 is set as an inclined surface, and the height of the top end surface 2001 gradually increases toward the direction close to the clearance hole 14;

[0052] The punch assembly 102 is provided with two sets of pressing assemblies corresponding to the two sets of clamping assemblies respectively;

[0053] The pressing assembly includes a support plate 18 connected to the punch assembly 102 , on which at least one first pressing elastic rod is movably arranged up and down, and a push rod 21 capable of cooperating with the top end surface 2001 is connected to the bottom end of the at least one first pressing elastic rod.

[0054] In this embodiment, a punch up and down driving device that can be used to drive the punch assembly 102 to move up and down should also be provided, and a cylinder, a motor, etc. can be selected. When in use, first place the parts to be processed on the support base 11 and in the area between the two clamping assemblies, and then move the punch assembly 102 downward so that the push rod 21 abuts against the top surface 2001 of the linkage block 20. As the push rod 21 gradually moves downward, the linkage block 20 will drive the clamping frame to move in the direction of the clearance hole 14. In this process, the clamping elastic rod will be compressed and move with the clamping frame. When the two clamping frames move synchronously to the two sides of the parts to be processed, the parts to be processed can be centered. Positioning processing can also be performed; as the punch assembly 102 moves further downward, the push rod 21 will compress the first downward-pressing elastic rod so that it moves upward relative to the support plate 18 to make way for the distance requirement, and then the punch 103 can be used for punching the parts to be processed; after punching, the punch assembly 102 will gradually reset and move upward. In this process, when the linkage block 20 loses the abutment of the push rod 21, it will gradually drive the clamping frame to reset under the elastic reset force of the clamping elastic rod, thereby facilitating the unloading of processed parts.

[0055] Preferably, at least one second downward-pressing elastic rod is movably disposed on the support plate 18 , and the bottom end of the at least one second downward-pressing elastic rod is connected to the downward-pressing plate 19 located on the inner side of the pushing rod 21 .

[0056] In this embodiment, Figure 1 and Figure 2 As shown, in the absence of external force, the lower pressure plate 19 should be located above the push rod 21. In this way, after the clamping assembly has centered the parts to be processed, as the punch assembly 102 continues to move downward, the lower pressure plate 19 will press the parts to be processed onto the support base 11, so that the stability of the parts positioning can be further improved. As the punch assembly 102 moves further downward, the lower pressure plate 19 will compress the second downward elastic rod to move it upward relative to the support plate 18 to make way for the distance requirement. When the punch assembly 102 is reset, the lower pressure plate 19 and the push rod 21 can both be reset to release the positioning effects such as pressing and clamping on the processed parts.

[0057] like Figure 2 As shown, each pressing assembly may be provided with a first pressing elastic rod connected to the push rod 21 , and may be provided with two second pressing elastic rods connected to the pressing plate 19 .

[0059] The second downward-pressing elastic rod includes a second T-shaped guide rod 201, the bottom end of the second T-shaped guide rod 201 passes through the support plate 18 and is connected to the downward-pressing plate 19, and the second downward-pressing elastic rod also includes a second spring 202 sleeved on the second T-shaped guide rod 201, and the upper and lower ends of the second spring 202 are respectively abutted against the support plate 18 and the downward-pressing plate 19, so that: the T-shaped head of the second T-shaped rod 201 is pressed against the support plate 18.

[0060] In this embodiment, in addition to the reset function, the first spring 302 can also give the push rod 21 a force to continuously abut against the top surface 2001, and the second spring 202 can also give the lower pressing plate 19 a force to continuously press the part to be processed.

[0061] Preferably, the clamping frame comprises a connecting section 12 , and both ends of the connecting section 12 are connected with obliquely arranged clamping sections 13 .

[0069] When the present embodiment is used, when the punch assembly 102 moves downward and the punch 103 acts on the part to be processed, the movable plate 16 can provide soft support for the punch 103, so that the punching quality can be guaranteed. When the punch 103 passes through the part quickly, the movable plate 16 will be forced to compress the stamping spring 603 to make way for the distance requirement. Among them, the cooperation between the stamping sleeve rod 602 and the stamping sleeve 601 can improve the stability of the movable plate 16 moving up and down.

[0075] During use, the waste material after punching will remain on the movable plate 16. The first motor 506 drives the mounting plate 15 and the movable plate 16 to move upward, so that the waste material can be pushed out of the clearance hole 14. At this time, the waste material can be transferred manually or by other automated equipment. In addition, when the movable plate 16 moves up and down, the punching holes of the processed parts can be polished to reduce burrs.

At this time, the mounting plate 15 will drive the piston plate 702 to move upward, so that it transfers the gas stored in the inflation box 701 to the movable plate 16 and blows it out from the blowing hole 17.

[0088] 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.
