Description

Wire EDM electric installation

Technical field

The utility model relates to wire cutting machine technical field, especially relates to a kind of Wire EDM electric installation.

Background technology

At present, conducting block on wire cutting machine tool generally adopts Hardmetal materials to make, process principle produces high temperature by workpiece corrode by sparking between line of cut and workpiece two electrodes, in cutting on line process, line of cut contacts with conducting block all the time, and relative sliding, by conducting block, work electricity is incorporated into a formation electrode on line of cut, conducting block is static is fixed on guide frame, line of cut moves, along with line of cut and conducting block Long contact time, friction, electric discharge, the groove of certain depth is formed in the position that conducting block contacts with line of cut, line of cut continues to move easily by clamp along groove, cause broken string, line of cut is caused to be scrapped, thus also sink money (because molybdenum filament is somewhat expensive while of having a strong impact on production efficiency, and molybdenum filament break just can not again with changing), for reducing broken string, need often to change conducting block and line of cut contact position, existing method of adjustment be by conducting block around a certain angle of own axis, line of cut is contacted in the position that conducting block is new, along with conducting block circular-rotation one enclose after, groove is covered with in circumference on conducting block cross section, this conducting block is scrapped, change by new conducting block, too early being scrapped of the conducting block changed, cause the wasting of resources, increase processing cost.

Utility model content

Based on this, be necessary for the deficiencies in the prior art, a kind of Wire EDM electric installation is provided, driving conducting block to rotate by increasing drive unit, thus providing more position to contact with line of cut, reach prolongation conducting block service life, cut down finished cost, the object economized on resources, structure is simple simultaneously, easy to operate.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Wire EDM electric installation, it comprises drive unit, conducting block and line of cut, described conducting block is arranged on described drive unit one end, described line of cut fit described conducting block arrange, described line of cut and conducting block axle core place included angle of straight line are less than 90 degree.

Wherein in an embodiment, described drive unit is provided with motor and rotating shaft, and described motor driving rotating shaft is rotated, and described conducting block is fixedly connected on described rotating shaft one end.

Wherein in an embodiment, described rotating shaft is isolation material structure.

Wherein in an embodiment, described conducting block is cylindrical structure.

Wherein in an embodiment, described conducting block two ends are respectively arranged with carbon brush, described carbon brush external electrode silk.

In sum, the utility model, by conducting block is fixed on drive unit one end, utilizes drive unit to drive conducting block to rotate, simultaneously, the angle of line of cut and conducting block is set to be less than 90 degree, increase the contact area between line of cut and conducting block when line of cut carries out cutting processing workpiece, reduce the wearing and tearing of line of cut to the single position of conducting block, reach and extend conducting block service life, cut down finished cost, the object economized on resources, structure is simple simultaneously, easy to operate.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model Wire EDM electric installation.

Detailed description of the invention

For feature of the present utility model, technological means and the specific purposes reached, function can be understood further, below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.

As shown in Figure 1, the utility model Wire EDM electric installation comprises drive unit 10, conducting block 20 and line of cut 30, described drive unit 10 is provided with motor 11 and rotating shaft 12, described motor 11 drives rotating shaft 12 to rotate, described rotating shaft 12 is isolation material structure, and described conducting block 20 is arranged on described drive unit 10 one end, particularly, described conducting block 20 is fixedly connected on described rotating shaft 12 one end, and described conducting block 20 rotates along with the rotation of rotating shaft 12.

Described line of cut 30 described conducting block 20 of fitting is arranged, and described line of cut 30 is molybdenum filament structure.

Wherein in an embodiment, described conducting block 20 is cylindrical structure; Described line of cut 30 is less than 90 degree with conducting block 20 axle core place included angle of straight line, and described conducting block 20 two ends are respectively arranged with carbon brush 21, and described carbon brush 21 external electrode silk, makes conducting block 20 charged by the electric connection mode of wire electrode and carbon brush 21.

During the utility model embody rule, because line of cut 30 contacts with conducting block 20, such that line of cut 30 is charged completes Linear cut operation to processing work, in cutting on line process, line of cut 30 contacts for a long time with conducting block 20; Simultaneously, conducting block 20 slowly rotates under the drive of drive unit 10, be on-right angle state because line of cut 30 closes with the angular position of conducting block 20, when conducting block 20 rotates, line of cut 30 can touch the surface of conducting block 20 more in large area, avoid the damage because causing conducting block 20 after line of cut 30 for a long time running, further increase line of cut 30 and the service life of conducting block 20, cut down finished cost, the object economized on resources, structure is simple simultaneously, easy to operate.

In sum, the utility model Wire EDM electric installation is by being fixed on drive unit 10 one end by conducting block 20, drive unit 10 is utilized to drive conducting block 20 to rotate, simultaneously, the angle of line of cut 30 with conducting block 20 is set to be less than 90 degree, the contact area between line of cut 30 and conducting block 20 is increased when line of cut 30 carries out cutting processing workpiece, reduce the wearing and tearing of line of cut 30 pairs of single positions of conducting block 20, reach and extend conducting block 20 service life, cut down finished cost, the object economized on resources, structure is simple simultaneously, easy to operate.

The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with claims.
