During the process of taper processing, the injection of working solution conducts self tracking along with the inclination of a wire electrode all the time, and the working solution constantly is accumulated as a columnar shape to wrap the wire electrode, thus improving the gloss finish, accuracy and efficiency of linear cutting process and obtaining good punching and chip removal effect and better cooling effect.
Description
(1) technical field:
The utility model relates to the electric spark linear cutting machine technical field, especially a kind of equipment water jetting cooler of edm of big taper bed.
(2) background technology:
The edm of big taper bed is meant flexible and swing campaign about the last rotating shaft of coil holder that main dependence is equipped with the tapering head doing in horizontal plane, regulate the cutting angle of active section wire electrode, to realize workpiece is carried out the electric spark linear cutting machine of big tapering processing to workpiece.
In the prior art, the above-mentioned wire cutting machine tool that can cut big tapering workpiece, the equipment water jetting cooler of its wire electrode, the active section that normally adopts a spray nozzle to aim at wire electrode carry out water spray (liquid) cooling of vertical direction, play the chip removal effect simultaneously.Hole on the water spout can not be done too greatly (because of the cooling water that gushes out behind the Kong Taida because edm of big taper bed electrode silk angle of inclination is bigger, can not form water column and too diffusing), so, after the angle increase that the active section wire electrode tilts, the weak point of this structure also displays, water (liquid) cylinder of ejection is long-pending to be concentrated greatly and not, especially the cooling fluid of mouth spray ejection just is easy to leave the wire electrode active section, do not have cooling effect, certainly do not have the chip removal effect yet, the scaling loss of wire electrode will be caused like this and fracture of wire, and the machining accuracy of workpiece can be influenced.Simultaneously, the wire electrode angle of inclination is big, water spout may be cut damage.
In view of this, (applying date: September 28 nineteen ninety) " equipment water jetting cooler of edm of big taper bed " by name proposed following technical solution: it comprises horizontal U-shaped water plate to Chinese patent 99239799.5, the end of U-shaped water plate is provided with inlet opening, bipod is provided with fluid hole, the hole wall of fluid hole is provided with several water spouts, is the wire groove between the bipod of U-shaped water plate.This technical scheme is by being provided with several water spouts on the hole wall of fluid hole, guaranteeing has the part cooling fluid scattering to be sprayed on the active section of wire electrode all the time, thereby guarantees wire electrode is carried out cooling effect.Its weak point is and since in the tapering process hydrojet Shu Buneng of working solution with the inclination of wire electrode from line trace, thereby most of cooling fluid is inoperative, cooling effect is poor, the chip removal weak effect.In addition, a plurality of hole for water sprayings also form spray easily and splash not environmental protection.Need be improved.
(3) summary of the invention:
The utility model aims to provide the equipment water jetting cooler of the better edm of big taper bed of a kind of cooling effect.
