Problems solved by technology

However, in this power feeding mode, in the process of leading the external power to the guide wheel, due to the small outer diameter of the guide wheel, there is a relatively high-speed relative frictional movement between the power feeding terminal and the power feeding point of the guide wheel, and the friction The heat generated by the movement affects the service life of the guide wheel power feeding device, and the friction force will also affect the stability of the guide wheel movement

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as Figure 4 , 5 As shown in . 32. The elastic fixing piece 33 and the static feeding body 34 are composed of the spring 32 in the cavity of the terminal body 31, the elastic fixing piece 33 is installed on the terminal body 31, the static feeding body 34 is embedded in the elastic body 32, and the feeding guide wheel 2 Both ends of the main shaft 23 are embedded with a moving electric body 21.

[0032] The main shaft of above-mentioned feeder guide wheel 2 can only be provided with above-mentioned feeder at one end, also can establish identical two sets of feeder at two ends.

[0033] The external power supply 8 is connected to the terminal main body 31 of the power-feeding terminal 3, and then passed to the dynamic power-feeding body 21 of the power-feeding guide wheel 2 through the static power-feeding body 34 on the elastic ...

Abstract

The present invention relates to a guide wheel power-feeding device of electric spark linear cutting machine equipment. It is composed of supporting frame, power-feeding guide wheel and power-feeding terminal, said power-feeding terminal is formed from terminal main body, spring and static power-feeding body. The spring is limited in the terminal main body cavity, one end of said spring is connected with static power-feeding body, said static power-feeding body is contacted with power-feeding guide wheel axle, the above-mentioned power-feeding guide wheel and power-feeding terminal main body are mounted on the supporting frame. The described guide wheel is made up by butt-jointing thin sheets. Said invention can obviously raise its machining accuracy.

Description

technical field [0001] The invention relates to a guide wheel power feeding device of a wire electric discharge machine tool device. Background technique [0002] During the processing of wire electric discharge machine tools, the stability of the power feeding device seriously affects the discharge state of the electrode wire, and the discharge state of the electrode wire seriously affects the cutting performance of the machine tool. The existing power feeding device generally adopts the asynchronous power feeding method (such as figure 1 ), the power supply block 6 is in contact with the wire electrode 4 at one part of the wire transport path, the external power source 8 is connected to the power supply block 6, and then passed to the wire electrode 4 through the power supply block 6 for cutting of the wire electrode 4 . When the machine tool cutting process is powered, the electrode wire and the power supply block have a relative movement. There are also synchronous po...
