Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire cutting filter technology, specifically a wire cutting filter screen. Background Technology
[0002] Slow wire EDM is a type of electrical discharge wire EDM that uses a continuously moving thin metal wire (called the electrode wire) as an electrode to perform pulsed spark discharge cutting on the workpiece. In wire EDM, the coolant primarily serves for cooling, chip removal, and insulation. During processing, the waste generated by the workpiece circulates with the coolant. When the waste accumulates to a certain proportion in the coolant, it will clump together and adhere to the coolant delivery pipes of the wire EDM machine, easily causing blockages.
[0003] Wire EDM in physical and chemical testing laboratories is mainly used for cutting notches in rail fracture toughness and crack propagation specimens. This process generates many cutting fragments that scatter across the wire EDM platform. Because these fragments are very light, some flow with the cutting fluid during the fluid recovery process and become trapped in the bends of the pipe, making them impossible to remove. As the number of blocked fragments increases, it severely affects fluid recovery and consequently, the normal operation of the wire EDM. Therefore, this invention provides a wire EDM filter to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a wire-cut filter screen to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire-cut filter screen, comprising a first mounting frame, a second mounting frame, and a filter pad, wherein the first mounting frame is provided with a second mounting frame having a symmetrical structure on the right side, and the first mounting frame and the second mounting frame have the same structure, and connecting ears are welded to both the front and rear ends of the first mounting frame and the second mounting frame, and fixing bolts are installed on the connecting ears;
[0006] Both the first and second mounting brackets have strip-shaped mounting grooves on their inner sides, and both ends of the mounting grooves are through-hole structures. Filter pads are installed in the mounting grooves of the first and second mounting brackets. Screws are installed on the upper surfaces of the first and second mounting brackets, and the screws pass through the filter pads and fix them. Filter holes are provided on the filter pads.
[0007] In a preferred embodiment of this invention, both the first mounting bracket and the second mounting bracket are mounted on the wire cutting filter using fixing bolts.
[0008] As a preferred embodiment of the present invention, screws are embedded on the upper surfaces of the first mounting bracket and the second mounting bracket, and the upper surfaces of the screws are flush with the upper surfaces of the first mounting bracket and the second mounting bracket, respectively.
[0009] As a preferred embodiment of this invention, the filter pad is a rectangular rubber pad with a length of 45mm, a width of 66mm, and a thickness of 5mm.
[0010] As a preferred embodiment of this invention, the filter pad has a honeycomb structure with a pore diameter of 2 mm.
[0011] In a preferred embodiment of this invention, the thickness of the filter pad is less than the height of the mounting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, the filter pad is cut to size according to the groove of the filter. Then, both ends of the filter pad are installed in the mounting grooves at the inner ends of the first mounting bracket and the second mounting bracket, respectively, and fixed with screws to increase the firmness. Then, the filter pad is laid at the groove of the filter, and the first mounting bracket and the second mounting bracket are fixed with fixing bolts to fit the filter pad into the groove of the filter. This solves the problem that cutting fragments flow with the cutting fluid to the cutting fluid recovery pipe and block the inside bend of the pipe, which seriously affects the recovery of cutting fluid, and improves the recovery and utilization rate of cutting fluid.
