Elastic sheet riveting device

Abstract

The invention discloses an elastic sheet riveting device for riveting of a workpiece and an elastic sheet. The elastic sheet riveting device comprises a base, an abutting pier, a pressing block, elastic supporting columns, a casing and a plunger; the abutting pier is arranged on the base, and is used for abutting against a riveting point of the workpiece and a rivet / salient point on the riveting point; the pressing block is arranged above the base through the elastic supporting columns, moves downwards under the pressure applied to the top of the pressing block, and can return to an original place under the action of elastic force of the elastic supporting columns; the casing is provided with a through hole; the top of the casing is arranged below the pressing block through a spring; a pitstructure for fixing the elastic sheet is arranged at the middle part of the casing; the plunger is sleeved by the through hole of the casing and is arranged below the pressing block through a springat the top; and under the driving of the pressing block, the casing can allow the elastic sheet to abut against the rivet / salient point, while the plunger can rivet the elastic sheet and the workpiece through the rivet / salient point. Phenomena of deflection riveting and virtual riveting which are easily caused by manually placing the elastic sheet are avoided, the working efficiency and the product yield are improved and raised, and the elastic sheet riveting device has the beneficial effects of convenience in manufacturing, low cost, reasonable and compact structure, simplicity and reliability in operation and the like, and has extremely high popularization and application values.

Description

technical field [0001] The invention relates to a shrapnel riveting device, which belongs to the technical field of sheet metal processing equipment for metal products. Background technique [0002] When the workpiece is processed in sheet metal, it is often necessary to rivet the shrapnel and the workpiece together. When riveting, the shrapnel is generally placed on the riveting point where the workpiece needs to be riveted, and then the rivet at the riveting point is pressed against the cross-shaped head of the punch or Bumps to complete the riveting. Therefore, accurately placing the shrapnel on the rivets or bumps that need to be riveted to the workpiece is the key to ensure the qualified riveting of the shrapnel and the workpiece. [0003] If there is a large space around the riveting point of the workpiece, it is easier to place the shrapnel, but if the space around the riveting point of the workpiece is very narrow, it is not easy for the operator to place the shrapn...

Problems solved by technology

[0003] If there is a large space around the riveting point of the workpiece, it is easier to place the shrapnel, but if the space around the riveting point of the workpiece is very narrow, it is not easy for the operator to place the shrapnel accurately on the riveting point of the workpiece, which often causes deviation Or if the placement is not in place, it will cause partial riveting and false riveting between the shrapnel and the workpiece, resulting in unqualified products. In actual production, when the shrapnel is placed manually for riveting, the efficiency is often extremely low and the scrap rate is extremely high, seriously affecting production efficiency and economic benefits
