A bidirectional loading electromagnetic riveting device

Abstract

The invention relates to a both-way loading electromagnetic riveting device. The both-way loading electromagnetic riveting device comprises a bottom plate. A support used for clamping a riveting plate is arranged on the upper surface of the middle portion of the bottom plate. Sliding rails are symmetrically arranged on the two sides of the support on the bottom plate, and sliding blocks matched with the sliding rails are symmetrically arranged on the two sides of the support on the bottom plate. The sliding rails are located on the long axis of the bottom plate. The upper portion of each sliding block is provided with four supporting wedge blocks used for supporting and containing a riveter body. Each riveter body is of a cylindrical structure, and the arc-shaped faces of the riveter bodies are placed on the supporting wedge blocks. Fixing side plates are symmetrically arranged at the two ends of the bottom plate, through holes are punched in the fixing side plates, and a screw penetrates the through holes. One end of the screw is connected with the tail portions of the riveter bodies and used for controlling the movement of the riveter bodies in the axis direction. According to the both-way loading electromagnetic riveting device, the movement stability and directivity of the riveter bodies in the axial direction are improved. Great convenience is brought to adjustment of the positions of riveter heads, the consistency of the axis directions of the two riveter heads can be guaranteed, and both-way loading electromagnetic riveting is facilitated.

Description

technical field [0001] The invention relates to the field of electromagnetic riveting, in particular to a bidirectional loading electromagnetic riveting device. Background technique [0002] Electromagnetic riveting is one of the applications of electromagnetic forming technology in the field of mechanical connection. Electromagnetic riveting is a new connection process that converts electric field energy into mechanical energy to cause plastic deformation of rivets. Compared with traditional riveting, the electromagnetic riveting shank deforms evenly, and can be used for forming difficult-to-form materials and large-diameter rivets. It is an effective connection method to realize the structural connection of composite materials, and is widely used in the field of aerospace fastener connections. Electromagnetic riveting equipment includes two parts: energy storage system and riveting gun device. The riveting gun is mainly an electromagnetic force generating device. In orde...

Problems solved by technology

[0003] The riveting process of headed rivets is a one-way loading mode. One-way loading is likely to cause uneven deformation of the shank, and the part near the head has less interference and poor sealing.
