Problems solved by technology

The traditional punching riveting machine mostly adopts a hydraulic structure, and its oil pipes, joints, hydraulic pumps, and reversing valves are prone to oil leakage
It will cause unreliable punching riveting quality, which will affect product quality and reliability
Most of the existing pneumatic riveting devices are single-directional punching riveting operations, that is, performing single-directional punching riveting operations on the workpiece, and the operation of the device is relatively complicated
None of the above riveting devices can meet the actual needs

Abstract

The invention discloses a pneumatic punching-riveting device and relates to the technical field of punching. The pneumatic punching-riveting device comprises a body, pistons, springs and an adjusting screw; a station containing a work-piece to be punched and riveted is arranged in the body, and the adjusting screw is arranged on the bottom of the station for vertically adjusting the position of the work-piece to be punched and riveted from the bottom; guide grooves are formed in the body, the pistons and the springs are arranged inside the guide grooves, the pistons face the position to be punched and riveted of the work-piece to be punched and riveted, and the springs are arranged at the front ends of the pistons and are used for enabling the pistons completing the punching-riveting work to be reset; air channels are formed in the body and communicate with the guide grooves, and high-pressure gas in the air channels enter the guide grooves for impacting the pistons and enabling the pistons to execute the punching-riveting work. According to the device, use of hydraulic structures is avoided, and oil leakage is avoided. In addition, the pneumatic punching-riveting device is safe, reliable, simple in structure, convenient to operate, capable of carrying out the punching-riveting work in multiple directions and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a pneumatic riveting device, which is suitable for the multi-directional punching and riveting process of various workpieces. Background technique [0002] Pneumatic punching riveting device is a device that uses air pressure for punching riveting operations. The punching riveting process means that the workpiece is placed on the press, and the axial force is directly applied through the punch to make the material expand in the radial direction to achieve the purpose of plastic deformation. The traditional riveting machine mostly adopts hydraulic structure, and its oil pipes, joints, hydraulic pumps and reversing valves are prone to oil leakage. It will cause unreliable punching riveting quality, and then affect product quality reliability. Most of the existing pneumatic riveting devices are single-directional punching riveting operations, that is, performing single-directiona...
