Abstract
The utility model relates to a guide wheel for a wire cut electrical discharge machine. The guide wheel comprises a guide wheel body and a wire groove, a high-strength elastic wear-resistant layer is arranged on the wire groove, a molybdenum wire clamp is arranged on the inner wall of the wire groove, and the end face of the molybdenum wire clamp is a bevel. The guide wheel is simple in structure and reasonable in design, wear resistance of the guide wheel is improved, insulativity of the guide wheel is improved, service life of the guide wheel is prolonged, and production cost is lowered; a V-shaped groove is replaced by a U-shaped groove, so that damage to a molybdenum wire is prevented; due to arrangement of the wire clamp, the molybdenum wire is effectively avoided from being separated from the U-shaped groove in the process of wire drawing.
Description
Technical field
The utility model relates to a kind of wire cutting machine part field, relates in particular to a kind of WEDM guide wheel.
Background technology
Wire cutting machine tool is mainly made up of main frame, high frequency electric source and controller three parts.Wherein main frame is made up of lathe bed, coordinate table, wire storage tube, coil holder, working liquid container and annex etc.The molybdenum filament of processing use is on wire storage tube, and workpiece is placed on the fixture of workbench, fixes with bridge screw.In the time that console sends signal output pulse, stepper motor, by signal rotation, via change-speed gearing, feed screw nut auxiliary driving workbench, reaches the geometric object such as cutting straight line, circular arc.
Wire cutting machine is in work, need to carry out cooling to wire electrode, working solution just has influence on the water proofing property of guide wheel in cooling to wire electrode, and, wire electrode friction always on guide wheel drives guide wheel rotation, so also can cause guide wheel " V " profile Fast Wearing, after long-time wearing and tearing, cause the precision of guide wheel to reduce, affect the precision of product.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of WEDM guide wheel is provided.
The utility model is to be achieved through the following technical solutions:
A kind of WEDM guide wheel, comprises guide wheel body and wire casing, and described wire casing is provided with high strength elastic wearing layer, and the thickness of described high strength elastic wearing layer is 0.3-0.8mm, is provided with molybdenum filament line card simultaneously on wire casing inwall.
Further, described wire casing is " U " type.
Further, described high strength elastic wearing layer is made up of CH-804 elastomeric material.
Further, the end face of described molybdenum filament line card is inclined-plane.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, have improved the wearability of guide wheel, have also improved the insulating properties of guide wheel simultaneously, in the service life of having improved greatly guide wheel, have reduced production cost; By " V " type groove is replaced to " U " type groove, prevent the damage of molybdenum filament, arranging of line card effectively avoids it in drawing process, to depart from " U " type groove.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A part enlarged drawing in Fig. 1.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is A part enlarged drawing in Fig. 1.
Described a kind of WEDM guide wheel, comprise guide wheel body 1 and wire casing 2, described wire casing 2 is " U " type, described " U " molded line groove 2 be provided with high strength elastic wearing layer 3, on wire casing 2 inwalls, be provided with molybdenum filament line card 4, the end face 41 of described molybdenum filament line card 4 is inclined-plane simultaneously.
The thickness of described high strength elastic wearing layer 3 is 0.3-0.8mm, and it is made up of CH-804 elastomeric material.
To sum up, the utility model is simple in structure, reasonable in design, has improved the wearability of guide wheel, has also improved the insulating properties of guide wheel simultaneously, in the service life of having improved greatly guide wheel, has reduced production cost; By " V " molded line groove is replaced to " U " molded line groove 2, prevent the damage of molybdenum filament, arranging of line card 4 effectively avoids it in drawing process, to depart from " U " molded line groove 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
