Abstract

The invention relates to an electric spark deposition contact force control device with a damping function. The device is mainly composed of a cylinder, a slide table, a base, a weight, a clamping mechanism, an angle adjustment device, a throttle valve, a pressure gauge and an air valve, etc. , the moving direction of the cylinder piston is consistent with the moving direction of the sliding table. When the piston moves, it drives the sliding table to move, thereby driving the electrode to move up and down. When moving down, the electrode is in contact with the workpiece, and the thrust generated by the cylinder in the closed pneumatic system is used to offset the sliding parts. The gravity of the weight pushes the sliding part down to form the contact force between the electrode and the workpiece. The throttle valve in the airtight pneumatic system damps the movement of the piston and suppresses the recoil force caused by the movement of the electrode and the workpiece. Electrode vibration; in the process of EDM deposition welding, with the electrode loss and the movement of the sliding table, it can ensure the stable contact between the electrode and the workpiece and the constant contact force, reliable operation and convenient adjustment.

Description

technical field [0001] The invention relates to the technical field of electric spark deposition, in particular to an electric spark deposition contact force control device with a damping function. Background technique [0002] EDM surfacing technology is a surface treatment technology that utilizes tool electrode material migration to the workpiece surface during EDM to form a dense strengthening layer to form a dense strengthening layer, thereby improving the surface properties of the workpiece. [0003] In the process of EDM deposition welding, the electrode and the workpiece need to be in constant contact to generate electric sparks for deposition and surfacing. The contact force between the electrode and the workpiece is a key factor controlling the efficiency of deposition surfacing and the quality of the deposited layer. However, at present, EDM surfacing is mostly completed by manual operation. The staff usually rely on experience to maintain a certain contact force ...
