Abstract

The utility model provides a wire penetration free combined molybdenum wire guiding and locating device for a linear cutting machine tool. The guiding and locating device comprises a left assembly and a right assembly. The left assembly and the right assembly can be detachably matched. The left assembly comprises a left bottom case, a left guide wire insert, a left clamping block, a location pin and a left adjusting screw rod. The right assembly comprises a right bottom case, a right guide wire insert, a right clamping block, a location pin hole and a right adjusting screw rod. Due to the structure, semicircle holes of guide wires are formed in four sides of the left guide wire location insert and the right guide wire location insert, namely, durability of the left guide wire location insert and the right guide wire location insert is four times that of a common guide wire device, and therefore use cost is saved. The guide wire locating device adopts a combined type, so a cumbersome step of wire penetration when a molybdenum wire is installed is removed and auxiliary time for machining is saved. Combination of the two semicircle holes is adopted by the guide wire holes of the guide wire locating device, so playing or vibrating of the molybdenum wire is effectively prevented or reduced, and machining precision is improved. Compared with a common guide wire device, the guide wire locating device is simple in structure and easy to manufacture.

Description

It is guide locating device provided that the exempting from of wire cutting machine tool worn a combined type molybdenum filament

Technical field

The utility model relates to the device that a kind of wire cutting machine tool is used, and especially a kind of molybdenum wire is guide locating device provided.

Background technology

Present prior art, therefore the outstanding advantages such as allowance is little, machining accuracy is high because line cutting processing technology has, with short production cycle, low cost of manufacture obtain to use widely aborning.The general wire cutting machine tool of China all adopts the operating type of wire electrode fast turn-around at present, to reach higher efficient and lower cost, wire electrode normally adopts lower tumbler to be installed on bearing and the embedded axle bearing and locates, and wire electrode is larger at machining area section shake degree in cutting process, thereby cause machining accuracy to reduce, fineness is relatively poor.On the other hand, owing to reasons such as the kinematic accuracy of the damage of wire electrode, wire transporting device and system's control accuracies, so that wire electrode has play (or vibration) phenomenon and occurs in the wire transporting process, the wire electrode outside the processing district especially.When the wire electrode with play (or vibration) enters into the processing district, will have a strong impact on the wire electrode stability in the processing district, thereby affect the cutting processing precision of lathe.In order to eliminate or to weaken the play (or vibration) of wire electrode in wire transporting and process, need respectively to add a guide wire apparatus at the two ends of processing district.

A kind of guide wire apparatus is a cylinder, comprise metal ectosome and diamond endosome, the diamond endosome offers silk guide passage, this silk guide passage comprises lead-in wire entrance and the cylindrical channel that roughly is taper, this cylindrical channel has the effect of certain spacing and power to molybdenum filament, but molybdenum filament need to pass through diamond cylinder passage, install very inconvenient, and, because this cylindrical channel medial surface is that single line contacts with the molybdenum filament lateral surface, easily produces the stress concentration phenomenon, making diamond cylinder passage medial surface and molybdenum filament lateral surface is the wearing and tearing of single line contact edge, also make molybdenum filament produce the fatigue failure phenomenon, thereby affect the service life of molybdenum filament; Simultaneously, diamond cylinder passage medial surface contacts with the single line of molybdenum filament lateral surface, is easy to make molybdenum filament to produce play or vibration, affects the line cutting accuracy of linear cutting equipment.And a wire installation is opening form, although overcome molybdenum filament inconvenient shortcoming is installed, because molybdenum filament only has one side spacing in guide wire apparatus, another side is opening form, and the play of molybdenum filament (or vibration) is larger, thereby affects machining accuracy.

Summary of the invention
