A kind of electrode wire break-proof stabilizer of wire cutting machine tool
Technical field
The present invention relates to a kind of wire cutting machine tool appurtenances, be specifically related to a kind of electrode wire break-proof stabilizer of wire cutting machine tool.Wire cutting machine tool is a kind of high frequency voltage of using, the lathe that utilizes the mechanical movement of lathe that metal is cut.
Background technology
All there is following problem in wire cutting machine tool both at home and abroad at present.Job insecurity, wire electrode are elongated and cause the pine silk, wire electrode is shaken when cutting, cause work piece cut surface roughness instability, be difficult to reach the wire cutting machine tool design load, and the striped that cutting produces has a strong impact on work piece cut surface roughness and wire electrode life-span.Very easily be short-circuited when above and burn silk when thickness of workpiece reaches 60mm, directly wire electrode is blown when serious, wire electrode does not reach service life with regard to fracture of wire.Usually take tight silk wheel in the prior art, increase wire electrode tension, but this can't resolve wire electrode and be elongated the problem that causes the pine silk, the thrust of opposite tight silk wheel is big more, and the speed that wire electrode is elongated is fast more.Also have in the prior art and adopt two curled hair tubes, use the tight automatically silk of bi-motor Electronic Control, this apparatus cost height, easy to failure, it is difficult to repair, debug, and silk has been reduced the wire electrode life-span by unrestricted elongation.Installing electrodes silk difficulty is easily made mistakes.
Summary of the invention
At above-mentioned problems of the prior art, the objective of the invention is to propose a kind of electrode wire break-proof stabilizer of wire cutting machine tool, this stabilizer can make wire electrode operate steadily fixed and keep certain force of strain, makes wire electrode can unrestrictedly do not elongated and burn silk.
The technical scheme that the present invention is taked for its technical problem of solution: a kind of wire cutting machine tool polar filament break-proof stabilizer, comprise mainboard, fixed and arranged conducting block, silk pressing mechanism and locating piece successively on described mainboard are established gathering sill on the described locating piece; Described silk pressing mechanism is propped up by thread pressing board and thread pressing board and is configured to, and a side of described thread pressing board is movably connected between thread pressing board support and the locating piece.
The conducting surface of described conducting block and described gathering sill bottom are positioned at same plane, offer a water jet in the described gathering sill, and water jet is connected with the pipe joint of mainboard bottom, and described locating piece adopts the magnetic material.
Described thread pressing board is trisquare shape, is divided into the precompressed part and withholds part, and the precompressed segment thickness of thread pressing board is greater than the thickness of withholding part; When being in when withholding the position, to withhold part and withhold on locating piece, the precompressed part is between conducting block and locating piece, and the pressure surface position of precompressed part is lower than the conducting surface of described conducting block.
Described mainboard is connected with two connecting plates by adjustable plate, all establishes adjustment hole on adjustable plate and the connecting plate, establishes guide wheel between two connecting plates.
Break-proof stabilizer of the present invention need adopt two when using on wire cutting machine tool, be separately fixed at wire electrode vertical direction two ends up and down, the wire electrode operation is by conducting block, thread pressing block and locating piece, thread pressing block is pressed into arc with wire electrode, so just the vibrations resistance is rested the guide wheel place, resistance was bigger when break-proof stabilizer was passed through in the wire electrode operation, operated in two wire electrode discharge sections (cutting part) between the break-proof stabilizer and had all the time than hightension, made the wire electrode operate as normal.
Beneficial effect of the present invention: solved wire electrode and be directed at the wire electrode fluctuation of service and burn the silk problem, made the work piece cut surface roughness reduce the 1-2 level, prolonged the service life of wire electrode by unrestricted the elongation.

The specific embodiment
Referring to Fig. 1,2, the present invention is fixed and arranged conducting block 2, silk pressing mechanism 3 and a locating piece 4 successively on mainboard 14, establishes gathering sill 4-1 on the locating piece 4.Silk pressing mechanism 3 is made of thread pressing board 3-1 and thread pressing board support 3-2, and the side of thread pressing board 3-1 is movably connected between thread pressing board support 3-2 and the locating piece 4.Conducting block 2 adopts carbide alloy, diamond or other high-abrasive material, the conducting surface of conducting block 2 (i.e. the face that contacts with wire electrode) is in the same plane with described gathering sill 4-1 bottom, offer a water jet in the gathering sill, water jet is connected with the pipe joint of mainboard bottom.Locating piece 4 adopts the magnetic material.Thread pressing board 3-1 is trisquare shape, is divided into the precompressed part and withholds part, and the precompressed segment thickness of thread pressing board is greater than the thickness of withholding part.When being in when withholding the position, withhold part and withhold on locating piece 4, can make wire electrode 1 directed movement.The precompressed part is between conducting block 2 and locating piece 4, and the pressure surface position of precompressed part is lower than the conducting surface of conducting block 2.Like this when the gathering sill of conducting block 2, thread pressing board 3-1 and locating piece is passed through in wire electrode 1 operation, wire electrode 1 curved shape, referring to Fig. 3, make to operate in two wire electrode discharge sections (cutting part) between the break-proof stabilizer and have stable tension all the time, make the wire electrode operate as normal.Mainboard 14 is connected with two connecting plates 6 by adjustable plate 8, all establishes adjustment hole 6-1 on adjustable plate 8 and the connecting plate 6, establishes guide wheel 5 between two connecting plates 6.
During actual the use, need to adopt two break-proof stabilizers of the present invention on wire cutting machine tool, be separately fixed at wire electrode vertical direction two ends up and down, lead 11 is connected on respectively on the conducting block 2 of break-proof stabilizer up and down (the original conducting block of lathe is removed).
The invention solves in the prior art, be subjected to force unbalance when causing the wire electrode operation because of wire electrode operational system structure asymmetric, unlimited the causing with the conducting block loose contact to lax and vibrations of wire electrode discharged, and wire electrode contacts the problem that causes fracture of wire again with workpiece simultaneously.The present invention makes wire electrode reliably closely contact with conducting block, eliminated fully burn silk, blow, short circuit, improved the job stability of wire cutting machine tool, processed workpiece roughness reduces the 1-2 level, solve the problem of installing electrodes silk difficulty, prolonged the life-span of wire electrode simultaneously.
