Description

Technical Field

[0001] The present invention relates to the technical field of spring sheet production equipment, and in particular to a spring sheet stamping and forming device capable of quickly replacing a mold. Background Art

[0002] A spring sheet is a common mechanical part and is widely used in various fields. The spring sheet processing process first designs and manufactures a stamping mold according to the shape and size of the spring sheet. The blank is placed in the stamping mold, and pressure is applied through equipment such as a punching press to form the blank in the mold. During the stamping process, it is necessary to pay attention to controlling parameters such as the stamping speed and pressure to ensure the dimensional accuracy and surface quality of the spring sheet. For some spring sheets with complex shapes, multiple stampings may be required to complete the forming.

[0003] When the existing spring sheet stamping and forming device is in use, since the mold has always continued the traditional screw press-fitting and fixing technology, it takes a lot of time to perform complex mold disassembly and installation and debugging work, greatly increasing the equipment downtime. Moreover, during the cutting process of the stamped spring sheet, due to the vibration and offset of the material plate, its size deviates, affecting the product production quality. In addition, the material plate conveying action and the waste collection action need to be carried out in cooperation step by step, and the operation process is relatively cumbersome, resulting in poor production efficiency of the equipment.
