[0035] The working principle of this utility model:

[0036] When in use, the material is placed in the pressing seat 104, and then the pressing cylinder 102 is started and drives the pressing block 103 to move downward, and the pressing block 103 performs stamping and cutting work on the material. After completion, the pressing cylinder 102 drives the pressing block 103 to move upward, and then the linkage rod 14 is pressed to drive the movement of the moving rod 16. During the movement of the moving rod 16, the two linkage arms 17 are driven to move away through the linkage groove 18 respectively. The two linkage arms 17 respectively drive the two sliding blocks 20 to slide on the surface of the sliding arm 15, and drive the two fixed arms 21 to move away, thereby driving the two fixed blocks 22 to disengage from the positioning groove 11, and then the reset spring 12 drives the moving arm 5 to move upward through the limit block 7. The handle 10 is then rotated to drive the rotating shaft 9 to rotate, and the linkage gear 8 is driven to rotate, so that the linkage gear 8 drives the moving arm 5 to move downward through the groove 6, and at the same time drives the limit block 7 to squeeze the reset spring 12 and the moving block 2 to move downward. When it is rotated to a suitable number of circles, the linkage rod 14 is released, and the fixed spring 19 pulls the two linkage arms 17 to move closer and drives the two fixed blocks 22 to move closer through the fixed arm 21, so that the two fixed blocks 22 are respectively inserted into the inner wall of the positioning groove 11, thereby completing the fixation of the rotating shaft 9, and the next punching and cutting work can be carried out.

[0037] In summary: the stamping and cutting device for machining mechanical parts, through the coordinated use of the base 1, the moving block 2, the moving structure 3 and the positioning structure 4, solves the problem that after the stamping and cutting work of the mechanical parts is completed, the parts formed by extrusion are easily embedded in the mold body, making it difficult for the operator to remove the parts from the mold body. Forced removal may cause damage to the machine parts being machined, thereby affecting the appearance quality and service life of the parts.
