Abstract

The invention discloses a device for prolonging service life of a wire-electrode cutting conductive block. The device comprises an upper guide frame side wall, an insulation base, a conductive copper rod, an outer side locking nut, an electricity leading gasket, an inner side locking nut, a conductive block and a cutting wire. Compared with the single-side wall support conductive block, the device has the advantages of being good in rigidity and stable in position, achieving the purposes of prolonging the service life of the conductive block, reducing the processing cost and saving resources, and being simple in structure, convenient for operation and reliable in support position of the conductive block.

Description

A kind of extended line cuts the conducting block device in service life

Technical field

The present invention relates to special process Electric Discharge Wire-cutting Technology field, particularly relate to line cutting conducting block.

Background technology

In present Wire-cut Electrical Discharge Machining, along with line of cut directly contacts with conducting block for a long time, friction, discharge, groove at conducting block and the contacted position formation of line of cut certain depth, line of cut continues to move easily by clamp along groove, cause broken string, cause line of cut to be scrapped unusually in advance, for reducing broken string, need frequent conversion conducting block and line of cut contact position, the line of cut position is relatively constant, the conducting block position only changes, existing method of adjustment is that conducting block is rotated a certain angle around self axis, conducting block is contacted with line of cut in new position, when conducting block after radial circumference rotates a circle, groove is covered with in circumference at the conducting block cross section, this conducting block is scrapped, replaced by new conducting block, what the conducting block of changing was too early is scrapped, cause the wasting of resources, increase processing cost, existing conducting block support is unreasonable on the other hand, only depends on monolateral upper guide frame sidewall to support, the active force that conducting block is subject to line of cut produces distortion easily, causes the conducting block position stable not.

Summary of the invention

The conducting block life-span that the present invention be directed to existing Wire EDM is short, the defective that processing cost is high, provide a kind of extended line to cut the conducting block method and apparatus in service life, make conducting block can not only radially change the position and can change vertically the position, thereby provide more position to contact with line of cut, reach and prolong conducting block service life, cut down finished cost, the purpose that economizes on resources, have simultaneously simple in structure, easy to operate, the conducting block Support Position is reliable.

Technical scheme of the present invention is as follows:

Described extended line cuts the conducting block device in service life, comprise the guide frame sidewall, insulating base, the conduction copper rod, outside locking nut, draw electric packing ring, the inside lock jack panel, conducting block, line of cut, two insulating bases respectively by screw-threaded coupling in upper guide frame two side, conduction copper rod one end passes and draws electric packing ring, one side insulating base central through hole, the inside lock jack panel, conducting block, pass from opposite side insulating base central through hole, screw in respectively the conduction copper rod that two limits pass the insulating base central through hole with outside locking nut, by screwing the outside, two ends locking nut, the conduction copper rod is fixed on the insulating base, the conduction copper rod is provided with external screw thread along whole length direction, when needs are adjusted the conducting block radial position, unclamp conducting block one end inside lock jack panel, rotate conducting block to reposition, the inside lock jack panel that locking is unclamped is fixed in conducting block on the conduction copper rod, when needs are adjusted the conducting block axial location, unclamp conducting block two ends inside lock jack panel to suitable axial location, conducting block moves axially and screws with conducting block two ends inside lock jack panel, conducting block is fixed on the conduction copper rod, changes conducting block and line of cut contact position thereby reach.

The invention has the beneficial effects as follows: only compare that one-sided wall supports conducting block good rigidly, position stability, reach and prolong conducting block service life, cut down finished cost, the purpose that economizes on resources, have simultaneously simple in structure, easy to operate, the conducting block Support Position is reliable.
