Description

Wire cutting protector Technical Field The invention relates to the technical field of wire cutting processing, in particular to a wire cutting protection device. Background In the field of online cutting processing, a metal test piece is cut by a molybdenum wire under the drive of an electrifying and rotating wheel, cutting fluid sprayed out of an upper precious stone nozzle and a lower precious stone nozzle is used for cooling and lubricating in the cutting process, and the workpiece is in two conditions in the cutting dropping process, wherein the first condition is that the thickness of the workpiece is smaller than the distance between the workpiece and a supporting cantilever, the workpiece is completely separated from a cutting area after falling and colliding with the precious stone nozzle, the second condition is that the thickness of the workpiece is larger than the distance between the workpiece and the supporting cantilever, the workpiece cannot be separated from the cutting area after falling and colliding with the precious stone rocky point, and the workpiece is inclined and extruded and the precious stone nozzle is blocked in the subsequent processing and moving process, so that the molybdenum wire and the precious stone nozzle are damaged in an accelerating way. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a wire cutting protection device, which solves the problem that molybdenum wires and a precious stone nozzle below the molybdenum wires are easy to damage in the wire cutting processing process. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: the utility model provides a wire-electrode cutting protector, it includes the processing base and sets up the horizontal migration platform on the processing base, be provided with the cantilever crossbeam on the processing base and be used for the molybdenum filament of wire-electrode cutting work piece, the vertical setting of molybdenum filament is provided with the fixed cross beam that is used for fixed work piece on the horizontal migration platform, the cantilever crossbeam is last to inlay to be equipped with the precious stone nozzle, and the precious stone nozzle is located the below of molybdenum filament, be provided with protection platform on the cantilever crossbeam, protection platform's upper surface is close to the bottom surface of work piece, the last jet orifice of being convenient for the molybdenum filament to pass of seting up of protection platform. The technical scheme has the advantages that the workpiece cut by the molybdenum wire can fall onto the protection platform, the workpiece falling onto the protection platform is not prone to inclination and offset, the phenomenon that the molybdenum wire is broken due to the fact that the molybdenum wire is extruded by the workpiece in the wire withdrawing process is avoided, meanwhile, the upper surface of the protection platform is close to the bottom surface of the workpiece, and when the workpiece which is not cut and separated completely is offset downwards due to self gravity in the wire cutting process of the molybdenum wire, the protection platform can effectively support the workpiece, and smooth cutting of the molybdenum wire on the workpiece is facilitated. Further, the protection platform comprises a fixed base fixedly sleeved on the cantilever beam, a bearing support is arranged on the fixed base, a height adjusting frame is arranged on the bearing support, a bearing platform is arranged on the height adjusting frame, the spraying hole is arranged in the middle of the bearing support and the bearing platform, and a plurality of bearing supports which are flush in height are arranged on the bearing platform around the spraying hole. The technical scheme has the beneficial effects that the injection hole is convenient for the molybdenum wire to pass through and ensures the normal injection flow of the cooling liquid, and the bearing support can stably support the cut workpiece, and simultaneously reduces the contact area between the bottom of the workpiece and the bearing platform, so that the cut workpiece can stably slide on the bearing platform.
