Abstract

A wire cutting conductive block adjusting device comprises a locking nut, a conductive block, a cutting wire, a conductive block copper rod, a conductive block insulation rubber sleeve, a cutting wire support frame, an electricity lead-in ring and a plurality of adjusting shims, the adjusting shims which can be of three thickness specifications of 1mm, 2mm and 5mm are added between the conductive block copper rod and the conductive block insulation rubber sleeve, and a conductive block groove can be covered along the axial length after the adjusting shims are added. The conductive block is capable of moving along the axis thereof by adding the adjusting shims with different thicknesses, so that more positions are provided for contacting with the cutting wire, the service life of the conductive block is prolonged, processing cost is reduced, resources are saved, and the wire cutting conductive block adjusting device has the advantages of simple structure and convenience in operation.

Description

Wire EDM conducting block adjusting device

Technical field

The utility model relates to a kind of electric spark linear cutting machine, especially relates to the conducting block device of wire cutting machine tool.

Background technology

At present, the conducting block on the wire cutting machine tool generally adopts Hardmetal materials to process, and process principle is to produce high temperature with the workpiece corrode, in line cutting processing through sparking between line of cut and two electrodes of workpiece; Line of cut contacts with conducting block all the time, and relatively slides, and is incorporated into electrode of formation on the line of cut through the conducting block electricity of will work; The conducting block stationary is in guide frame, and line of cut moves, along with line of cut and conducting block Long contact time, friction, discharge; Form the groove of certain depth in the contacted position of conducting block and line of cut, line of cut continues to move easily by clamp along groove, causes broken string; Cause line of cut to be scrapped,, need often to change conducting block and line of cut contact position for reducing broken string; Existing method of adjustment is that conducting block is rotated a certain angle around self axis, and line of cut is contacted in the new position of conducting block, along with conducting block after circumference rotates a circle; Groove is covered with in circumference on the conducting block cross section, and this conducting block is scrapped, and is changed by new conducting block; The too early quilt of the conducting block of changing is scrapped, and causes the wasting of resources, increases processing cost.

Summary of the invention

The purpose of the utility model is short to the conducting block life-span on the present electric spark linear cutting machine, and the defective that processing cost is high provides a kind of through increasing the different adjustment pad of some thickness; Conducting block can be moved axially along self, thereby provide more position to contact, reach and prolong conducting block service life with line of cut; Cut down finished cost; Aim of saving has simple in structure, easy to operate simultaneously.

The technical scheme of the utility model is following:

Wire EDM conducting block adjusting device comprises that locking nut, conducting block, line of cut, conducting block copper rod, conducting block insulation gum cover, line of cut bracing frame, electricity are introduced and enclosed, the adjustment pad; The adjustment pad can be made up of 1mm, 2mm, three kinds of thickness specifications of 5mm; After increasing the adjustment pad, the conducting block groove can be covered with along the axial length;

The conducting block adjusting device is to install like this: earlier the conducting block copper rod is inserted in the conducting block insulation gum cover; Conducting block insulation gum cover is through being threaded into line of cut bracing frame and locking; Electricity is introduced snare and is gone into the conducting block copper rod outside and clamp electricity with locking nut to introduce circle simultaneously also with the conducting block copper rod position that is locked; Inboard at the conducting block copper rod, the conducting block and clamp of packing into locking nut, line of cut moves into the preparation that the Wire EDM conducting block is just accomplished on the conducting block surface; After processing a period of time; Groove at conducting block and the contacted position formation of line of cut certain depth; Unclamp the conducting block gum cover one side chain jack panel that insulate this moment; Make the conducting block copper rod in the middle of the protrusion step leave conducting block insulation gum cover vertically and enough adjust the distance that pad can insert for, the adjustment pad is inserted in conducting block copper rod protrusion step and conducting block insulate between the gum cover, the insulate locking nut of gum cover one side of the conducting block of screwing again; Conducting block can be moved axially along self, thereby provide more position to contact with line of cut.

The beneficial effect of the utility model is: through increasing the different adjustment pad of some thickness; Conducting block can be moved axially along self, thereby provide more position to contact, reach and prolong conducting block service life with line of cut; Cut down finished cost; Aim of saving has advantage simple in structure, easy to operate simultaneously.
