Embodiment 1

[0018] Such as figure 1 As shown, in order to realize the automatic EDM strengthening of the semicircular arc groove cylindrical workpiece workpiece 10, the workpiece must be continuously rotated V 1 , While the electric spark automatic strengthening electrode 1 performs intermittent half-circle rotation V 2 . The electric spark automatically strengthens the electrode and the vibration mechanism, which can automatically carry out a series of actions of capacitor charging-spark discharge-short-circuit contact-capacitor recharging, and can automatically compensate for the consumption of the electrode, so as to realize the automatic electric spark strengthening.

[0019] Such as figure 2 , 3 As shown, an automatic electric spark strengthening device for a cylindrical workpiece with a semi-circular arc groove on the surface includes an electric spark automatic strengthening vibration mechanism, and also includes a stepping motor 3, which is connected by a toggle link 4 The electric s...

Abstract

The invention relates to an automatic electric spark reinforcing device for cylindrical work pieces with semicircle surface and arc-shaped groove, comprising an automatic vibration reinforcing devicefor electric sparks and a step motor (3), wherein the step motor (3) is connected with the automatic vibration reinforcing device for electric sparks through a poking connecting rod (4); the front part of the automatic vibration reinforcing device for electric sparks is arranged on a platform (6) through a flexibly connected rotary pivot (2); a roller (8) on the rear part is positioned on the platform. The automatic electric spark reinforcing device for cylindrical work pieces has the advantages of precise positioning, speed and acceleration control, the ability to adjust motion radius according to the circular arc of work piece, convenient usage and evener coating.

Description

Technical field [0001] The invention belongs to an electric spark automatic strengthening device, in particular to an electric spark automatic strengthening device for a cylindrical workpiece with a semicircular arc groove on the surface. Background technique [0002] The loss of mechanical parts caused by wear is very huge, and the use of surface protection measures has become an effective way to solve the wear. Certain cylindrical workpieces with semi-circular arc grooves on the surface, such as rolls for rolling bars in steel mills, have high requirements for surface hardness, wear resistance, and high temperature resistance. The strengthening of such workpieces can start from the aspects of material and surface treatment. [0003] EDM surface strengthening is a process that uses the high-density energy of electric energy to strengthen the metal surface. It consists of pulse spark discharge between the electrode material and the surface of the metal material to infiltrate the ...
