Technical Field
[0001] This utility model relates to the field of stamping equipment, and in particular to a stamping equipment and a detachable mold. Background Technology
[0002] Stamping equipment is a type of mechanical equipment used for processing metal workpieces. It uses the pressure of dies and stamping presses to shape workpieces into parts of various shapes. This type of equipment is widely used in many industrial fields such as automobile manufacturing, aerospace, and home appliance production.
[0003] Currently, existing stamping dies are generally fixedly installed on stamping equipment, which limits the production of products of the same specifications. When different shapes of workpieces need to be processed, the entire die must be manually removed, which is time-consuming and affects work efficiency. Secondly, after stamping, the formed workpiece is usually flush with the stamping end face, making it inconvenient to remove. Although existing dies can use hydraulic cylinders to eject the formed workpiece, the instability of the hydraulic cylinders and wear on the top can easily cause the workpiece to deform during the stamping process, resulting in stamped products that do not meet requirements.

The push cylinder 13 pushes the sliding seat 70 out of the slide groove 14. Then, tighten the fastening screw 22 to detach the detachable mold 7 as a whole. This allows the sliding seat 70 with different diameter mounting holes 20 to be replaced. Next, the limit bushing 71 can be removed, allowing the formed fixed bushing 72 to be removed as well. The fixed bushing 72 mainly serves the forming function and is installed as a whole with the limit bushing 71. After the assembly is complete, the workpiece to be stamped is placed into the stamping hole 15 by the robotic arm. Then, press the replacement switch again. 19. This positions the detachable mold 7 in the stamping area. Then, press the stamping switch 18. This causes the controller 8 to control the solenoid valve 11, which in turn causes the hydraulic pump 10 to transmit hydraulic oil to the hydraulic cylinder 5 through the pipe 12. This causes the moving stamping seat 3 to move downward and stamp the workpiece. During the stamping process, the bottom of the workpiece pushes the connecting block 76 downward in the groove 24. When the bottom of the connecting block 76 contacts the top of the support column 74, the boss end face of the connecting block 76 is flush with it. Thus, during the stamping process, the workpiece remains inside the stamping hole 15. After the stamping is completed, the connecting block 76 moves upward under the action of the spring 75, which pushes the stamped workpiece out of the stamping hole 15 for easy removal.
