Description

Technical Field

[0001] The utility model relates to a stamping die of a stamping die head, in particular to a stamping die with a replaceable stamping die head, belonging to the technical field of stamping dies. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] The present publication number is 202123377842.3, which solves the problems that the existing stamping dies have that the die head is inconvenient to replace and the die is difficult to remove after stamping. The technical points are: it includes a stamping machine frame and a workbench, the workbench is provided with a stamping groove, and a lifting and ejection group is arranged inside the stamping groove, and a clamping group is arranged on the workbench, and a die head for stamping is arranged on the stamping machine frame, and a locking plug-in mechanism is connected to the die head, and the locking plug-in mechanism includes a connecting seat and a limiting plug-in group, and a guide lifting mechanism is arranged on the outer side of the connecting seat, the clamping group clamps the workpiece to be processed, the lifting drive group operates to realize the stamping of the die, and the limiting plug-in group realizes the installation and disassembly of the die head, and the lifting and ejection group can eject the workpiece when it is operated, which has the advantages of easy replacement of the die head and easy removal of the die after stamping.

[0004] The above solution has many benefits, but it also has the following problems:

[0005] (1) When the stamping die is used to process different types of workpieces, the staff needs to remove the original stamping die head, and then install the new stamping die head back to the original position and fix it. During the process of replacing the die head, the entire stamping die is always kept in a stopped state, and the stamping operation cannot be performed, which reduces the processing efficiency;

[0006] (2) When the stamping die is replacing the die head, the die head thread needs to be screwed into the threaded column. The efficiency of completely screwing the threaded column into the threaded column is slow, which in turn affects the efficiency of replacing the die head. Utility Model Content

[0028] The inner walls of the connecting seat 6 are fixedly connected with bearing seats 7, the inner ring of the bearing seat 7 is fixedly connected with a connecting rod 8, the connecting rod 8 is fixedly connected with the rotating block 5, and the relative rotation of the connecting seat 6 is realized through the bearing seat 7. The limiting mechanism includes a clamping seat 9, the bottom of the clamping seat 9 is fixedly connected with a spring 10 and a limiting block 11, the upper end of the spring 10 is fixedly connected with a movable plate 12, the upper end of the movable plate 12 is fixedly connected with a switch button 13 and a bayonet 14, and the bayonet (14) is inserted into the positioning groove 16 by resetting the spring 10. The inner wall of the connecting seat 6 is provided with a sliding groove 15 that matches the size of the bayonet 14. The sliding groove 15 is arc-shaped, and the connecting seat 6 is limited and fixed by inserting the pin 14 into the positioning groove 16.

The switch button 13 extends through the through hole to the outside to facilitate the operation of the staff. A positioning groove 16 matching the size of the pin 14 is provided at the bottom of the sliding groove 15. There are three positioning grooves 16. The position distribution of the positioning grooves 16 corresponds to the position of the stamping part 17. The connecting seat 6 is limited and fixed by inserting the pin 14 into the positioning groove 16.

[0029] Embodiment 1: When a stamping die with a replaceable stamping die head is used to process different types of workpieces, different types of die heads 20 can be installed on the connecting seat 6, and then the connecting seat 6 is rotated to make the pin 14 move relative to the sliding groove 15.
