Abstract
The invention discloses a valve element surface high-frequency pulse extrusion process. The valve element surface high-frequency pulse extrusion process comprises the following steps that a valve element obtained after finish machining is clamped on high-frequency pulse extrusion equipment; then the high-frequency pulse extrusion equipment is started; the resonant voltage and working current of the high-frequency pulse extrusion equipment are adjusted well; and the surface of the valve element obtained after finish machining is subjected to high-frequency pulse extrusion of 8500-9000 times per minute.

Accompanying drawing explanation
Fig. 1 is the process chart of a kind of spool face high-frequency impulse of the present invention extrusion process one preferred embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of spool face high-frequency impulse extrusion process, comprises the following steps:
(100) clamping: by the spool clamping after fine finishining on high-frequency impulse extrusion equipment, described high-frequency impulse extrusion equipment adopts the integrated high-frequency impulse control cabinet of 220V alternating voltage;
(200) control cabinet is started: start integrated high-frequency impulse control cabinet;
(300) high frequency resonant voltage is regulated: the resonance potential of described high-frequency impulse extrusion equipment is adjusted to 10V-12V;
