Description

A riveting upper mold for riveting contacts to sheets

technical field

The utility model relates to a device for fixing a contact point to a sheet material, in particular to a riveting upper mold for riveting a contact point to a sheet material.

Background technique

In the production of relays, the contact is generally fixed on the sheet by riveting through a riveting die. The current riveting dies directly rivet the contacts to the sheet. Although the process of fixing the contacts and the sheet can be completed, it is very easy for the sheet to shift during the riveting process, resulting in riveting gaps, sheet Insufficient fitting of the riveting lower mold causes problems such as riveting deformation, resulting in a low yield rate of this process.

Contents of the invention

The purpose of the utility model is to provide a riveting upper mold with a pre-pressing function for riveting contacts to sheets.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a riveting upper mold for riveting the contacts to the sheet, including an upper mold base that can be installed on a punch press, a riveting needle and a riveting needle that can be fixed on the On the rivet fixing block of the upper mold base, there is a T-shaped pre-pressing block under the rivet fixing block; a guide block is fixed on the lower surface of the rivet fixing block; the pre-pressing block can slide longitudinally in the guiding block; the pre-pressing block Slide down to stop at the anchoring surface in the guide block, and slide up to stop at the lower surface of the riveting pin fixing block; a compression spring is arranged between the riveting pin fixing block and the pre-pressing block; the riveting pin passes through the riveting pin fixing block, Compress the spring and the middle of the preload block.

The beneficial effects of the utility model are: due to the adoption of the above structure, before the riveting needle riveting the contacts and the sheet, the pre-pressing block first applies a certain pre-pressure to the sheet under the action of the elastic force of the compression spring, so that it will not move position; then during riveting, under the action of rigid pressure from the rivet needle fixing block and the upper die base, the sheet is closely attached to the riveting lower die, so that it will not be deformed at the moment of riveting.

The utility model is novel in design and reasonable in structure. It can provide pre-pressure to the sheet before riveting, and has the function of pre-pressing, so that the sheet can be completely positioned and closely attached to the riveting lower die, thereby avoiding riveting gaps and riveting. Deformation and other problems, improve the yield rate of contact and sheet riveting process.
