Description

Technical Field

[0001] The invention belongs to the technical field of riveting, and in particular relates to a riveting die with strong versatility and high stability. Background Art

[0002] With the development of technology, the types of riveting equipment are becoming more and more diverse. The existing handheld riveting machines are small in size, but the operator needs to hold the riveting machine for the entire process of riveting, and the parts to be riveted need to be kept fixed during the riveting process; non-handheld riveting machines are larger in size, but the operator only needs to place the parts to be riveted on the riveting machine and then turn on the switch to complete the riveting. Compared with handheld riveting machines, they are more efficient and have a higher yield rate. However, the existing non-handheld riveting machines can usually only adapt to a certain type of specific parts, have poor versatility, and require operators to manually position them. During the riveting process of the riveting machine, the operator also needs to manually keep the parts to be riveted stable, which not only affects the riveting efficiency, but also poses certain safety hazards.

[0005] With the above solution, when riveting is required, the part to be riveted is fixed on the positioning piece, at which time the part to be riveted has been pierced with rivets, the sliding seat 1 and the sliding seat 2 are aligned with the two ends of the rivet, and finally the top cover is moved in the direction close to the base. Since the sliding surface 1 and the sliding surface 2 are inclined, as the top cover moves, the sliding seat 1 and the sliding seat 2 move in the direction close to the positioning piece and apply force to the rivet, and the riveting can be completed. After the riveting is completed, in the process of the top cover moving away from the base, the sliding seat 1 and the sliding seat 2 are moved to a position where the riveted part can be easily removed under the action of the spring 1 and the spring 2.
