Abstract

The invention claims an adjusting device for an electric sparkle wire cutting conductive block, comprising a locking nut, a conductive block, a cutting wire, a copper rod of the conductive block, an insulating rubber sheath of the conductive block, a cutting wire supporting frame, an electric introducing ring and adjusting cushions, wherein several adjusting cushions added between the copper rod of the conductive block and the insulating rubber sheath of the conductive block can be constituted by three thickness sizes including 1 mm, 2 mm and 5 mm; and after additionally provided with the adjusting cushions, a conductive block ditch can be fully distributed along the axial length. Through addition of the adjusting cushions of different thicknesses, the conductive block can move along own axial direction, so as to provide more positions to contact with the cutting wire, and achieve the purposes of prolonging the service life of the conductive block, reducing the processing cost and saving the resource; and at the same time, the adjusting device is simple in structure and convenient in operation.

Description

Wire EDM conducting block adjusting device

Technical field

The present invention relates to a kind of electric spark linear cutting machine, especially relate 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 objective of the invention is to the weak point of the conducting block life-span on the present electric spark linear cutting machine, 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.

Technical scheme of the present invention 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; The method of adjustment of prior art is: conducting block one side chain jack panel is unclamped, conducting block is rotated a certain angle around self axis, line of cut is contacted in the new position of conducting block; Method of adjustment of the present invention is: the conducting block gum cover one side chain jack panel that insulate is unclamped; 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 between conducting block copper rod protrusion step and the conducting block insulation gum cover; The locking nut of the conducting block of screwing again insulation gum cover one side can move axially conducting block along self, thereby provides more position to contact with line of cut.

The invention has the beneficial effects as follows: 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.

The specific embodiment

Wire EDM conducting block adjusting device of the present invention comprises: locking nut, conducting block, line of cut, conducting block copper rod, conducting block insulation gum cover, line of cut bracing frame, electricity are introduced circle, 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.

Form the groove of certain depth in the contacted position of conducting block and line of cut, the method for adjustment before improving is that conducting block one side chain jack panel is unclamped, and conducting block is rotated a certain angle around self axis, and line of cut is contacted in the new position of conducting block.
