Description

Technical Field

[0001] This utility model relates to the field of molybdenum wire processing technology, specifically to a wire cutting molybdenum wire surface treatment device that facilitates positioning. Background Technology

[0002] Molybdenum wire mainly refers to a consumable made of precious metals such as molybdenum that is continuously moved with a high-voltage electric field to cut workpieces during wire EDM. Tungsten wire, on the other hand, requires surface treatment during the production process and needs to use surface spraying equipment.

[0003] Existing molybdenum wire surface treatment methods do not achieve ideal uniformity in spraying the molybdenum wire surface, and are prone to spray dead zones, which will affect the overall quality of the produced molybdenum wire.

[0004] Therefore, we propose a wire cutting molybdenum wire surface treatment device that is easy to position, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a wire-cut molybdenum wire surface treatment device that is easy to position, so as to solve the problem mentioned in the background art that the coating uniformity of existing molybdenum wire surface treatment is not ideal and easily affects the production quality of molybdenum wire.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire-cut molybdenum wire surface treatment device for easy positioning, comprising a support frame: Rollers are installed on both sides of the upper end of the support frame. A transmission frame is set on the upper left side of the support frame. An electric push rod is connected to the lower end of the transmission frame and a tensioning roller is connected to the upper end of the transmission frame. The upper end of the support frame is provided with a positioning frame, and guide wheels are connected to both sides of the positioning frame. A spray pipe is connected to the middle of the positioning frame, and a spray nozzle is connected to the inner wall of the spray pipe. The upper right end of the support frame is connected to a reciprocating lead screw, the upper end of the reciprocating lead screw is connected to a guide block, and the upper end of the guide block is connected to a second guide wheel.

[0007] Preferably, the electric push rod is fixed to the lower left end of the support frame, the transmission frame is rotatably connected to the tension roller, the lower ends of both sides of the transmission frame are slidably connected to the support frame, and the guide rods are slidably connected to the support frame.

[0008] Using the above technical solution, the electric push rod can drive the transmission frame and the tensioning roller to move up and down synchronously. When the tensioning roller moves, it can adjust the tension of the molybdenum wire so that the molybdenum wire can be kept taut and the molybdenum wire can be effectively positioned.

[0009] Preferably, the spray pipe is rotatably connected to the positioning frame, and the nozzles are arranged in a ring array on the inner wall of the spray pipe.

[0010] Preferably, a guide groove is provided on the outside of the spray pipe, and the nozzle is connected to the guide groove. A liquid storage tank is provided in the middle of the support frame, and a water pump is connected to the side of the liquid storage tank. The outlet end of the water pump is connected to a conduit, and the inlet end of the water pump is connected to the liquid storage tank. The outer wall of the spray pipe is rotatably connected to a guide ring, the front end of the guide pipe is connected to the guide ring, the front end of the guide pipe is in communication with the guide groove, the guide ring is sleeved outside the guide groove, and the guide ring is rotatably connected to the spray pipe.

[0011] Using the above technical solution, the liquid inside the storage tank can be transported to the conduit by the water pump, and then transported to the conduit and the conduit ring to the conduit channel. After being diverted by the conduit channel, it is sprayed outward by multiple sets of nozzles, which can spray the molybdenum wire surface from multiple angles.

[0012] Preferably, the right end of the spray pipe is connected to a toothed ring, the inner wall of the positioning frame is fixed with a first motor, the shaft end of the first motor is connected to a transmission gear, and the transmission gear meshes with the toothed ring.

[0013] By adopting the above technical solution, the first motor can drive the transmission gear to rotate, which in turn drives the gear ring and spray pipe to rotate, thereby realizing rotating spraying and improving the uniformity of spraying.

[0014] Preferably, the second guide wheel is rotatably connected to the guide block, and two sets of the second guide wheels are symmetrically distributed. The guide block is connected to the reciprocating screw, and the lower end of the guide block passes through the guide shaft. The guide block is slidably connected to the guide shaft, and the guide shaft is slidably connected to the guide block. The front end of the reciprocating screw is connected to the second motor, and the second motor is connected to the support frame through the support seat.

[0015] Using the above technical solution, the reciprocating screw can be driven to rotate by the second motor. When the reciprocating screw rotates, it can drive the guide block and the second guide wheel to reciprocate, thereby guiding the molybdenum wire to be wound up, ensuring that the molybdenum wire can be evenly wound around the outside of the roller shaft and improving the winding uniformity.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-position wire cutting molybdenum wire surface treatment device; 1. The molybdenum wire is precisely positioned and stably fed through a multi-layered structure. The electric push rod on the left can drive the transmission frame to adjust the tension roller up and down. With the limiting effect of the guide rod, the tension of the molybdenum wire can be adjusted in real time to ensure that it is always taut, providing a stable reference for subsequent processing. The guide wheels on both sides of the positioning frame and the second guide wheel group driven by the reciprocating screw on the right form a multi-directional guide. The second guide wheel moves back and forth along the guide axis with the guide block, which not only guides the direction of the molybdenum wire, but also ensures that the molybdenum wire is evenly wound during winding, avoiding deviation and further improving the positioning accuracy. 2. The device adopts a rotatable annular spray structure, which greatly optimizes the surface treatment effect. The water pump delivers the liquid in the storage tank to the guide channel of the spray pipe through the conduit and guide ring, and sprays it from multiple angles by the nozzles of the annular array. At the same time, the first motor drives the spray pipe to rotate through gear meshing, realizing 360° rotating spraying, which completely solves the problem of uneven spraying in one direction. This spray design allows the treatment liquid to fully cover the surface of the molybdenum wire, significantly improving the uniformity and effectiveness of surface treatment.
