Technical Field
[0001] This utility model relates to the field of wire EDM guide wire eye mold technology, specifically a wire EDM guide wire eye mold. Background Technology
[0002] In the tungsten-molybdenum wire cutting process, the wire EDM guide eye mold is a very important accessory. The wire EDM guide eye mold can reduce vibration and impact during processing, which helps to improve the processing accuracy and surface quality. It can also reduce the splashing and scattering of the processing fluid, avoiding adverse effects of the processing fluid on the processed parts, and further ensuring processing accuracy. In wire EDM, coolant is injected into the guide wire eyepiece to cool the tungsten-molybdenum wire. However, existing guide wire eyepieces on the market have poor cooling effect on the tungsten-molybdenum wire when guiding the coolant. Therefore, a wire EDM guide wire eyepiece is proposed to solve the above problems. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model discloses a wire cutting guide eye mold. The technical solution adopted is as follows: it includes an outer shell and a guide tube disposed inside it. The upper and lower ends of the guide tube are wire insertion ports. The outer shell is a cylindrical structure with a hollow interior and openings at the upper and lower parts. An annular mounting boss is provided at the center of the inner part of the outer shell. A mounting ring is provided on the outer side of the middle part of the guide tube. The mounting ring is locked above the mounting boss. A water inlet and a water outlet are opened on the side of the guide tube. The water inlet and the water outlet are located on the upper and lower sides of the mounting ring, respectively. A pressing cap is covered on the top of the guide tube. The lower end of the pressing cap is pressed against the mounting ring. The upper end of the wire guide tube protrudes from the upper surface of the pressing cap. A water injection hole is provided on the upper surface of the pressing cap. There is a gap between the outer wall of the wire guide tube and the inner wall of the outer shell. Tungsten-molybdenum wire passes through the wire threading port of the wire guide tube. The pressing cap and the mounting boss clamp the mounting ring, which facilitates the installation and fixation of the wire guide tube in the outer shell. Coolant is injected into the pressing cap through the water injection hole. The water inlet and outlet holes separated by the mounting ring enable the coolant to be effectively guided in the wire guide tube. The gaps between the outer shell and the wire guide tube, as well as between the pressing cap and the wire guide tube, allow the coolant to stably enter from the water inlet hole and exit from the water outlet hole.
[0004] As a preferred technical solution of the wire cutting guide eye mold of this utility model, a twisting rib is provided on the side of the outer shell, and an installation thread is provided on the side of the outer shell, with the installation thread located above the twisting rib. The outer shell is installed on the wire cutting machine by the installation thread, and the twisting rib is used to assist in twisting the outer shell.
[0005] As a preferred technical solution of the wire cutting guide eye mold of this utility model, the wire guide tube is provided with a wear-resistant guide block with a wire threading hole inside the wire threading port, and the tungsten molybdenum wire is guided by the wear-resistant guide block.
[0006] As a preferred technical solution of the wire cutting guide eye mold of this utility model, the outer end face of the mounting ring contacts the inner wall of the outer shell, and by limiting the diameter of the mounting ring, it is convenient to position and install the guide tube.
[0007] As a preferred technical solution of the wire cutting guide eye mold of this utility model, the lower outer side of the guide tube is inclined and close to the wire insertion port at the bottom of the guide tube, and the inclined surface is connected to the water outlet. Through the inclined surface at the lower end of the guide tube, the output coolant can be guided and made to gather on the output tungsten molybdenum wire for further cooling during cutting.
[0008] As a preferred technical solution for a wire cutting guide eye mold of this utility model, the wear-resistant guide block is made of diamond.
[0009] The beneficial effects of this utility model are as follows: The tungsten-molybdenum wire passes through the wire-feeding port of the wire guide cylinder. The mounting ring is held in place by the pressing cap and mounting boss, facilitating the installation and fixation of the wire guide cylinder within the outer casing. Coolant is injected into the pressing cap through the water injection hole. The water inlet and outlet holes separated by the mounting ring allow for effective guidance of the coolant within the wire guide cylinder. The gaps between the outer casing and the wire guide cylinder, as well as between the pressing cap and the wire guide cylinder, allow the coolant to stably enter through the water inlet and exit through the water outlet. The outer casing is installed on the wire cutting machine using mounting threads. Tightening the outer casing is assisted by turning the ribs. The tungsten-molybdenum wire is guided by wear-resistant guide blocks. The diameter of the mounting ring is limited, facilitating the positioning and installation of the wire guide cylinder. The inclined surface at the lower end of the wire guide cylinder guides the output coolant, causing it to converge on the output tungsten-molybdenum wire for further cooling during cutting.

The wear-resistant guide block 204 guides the tungsten-molybdenum wire. The outer shell 1 is a cylindrical structure with a hollow interior and openings at the upper and lower parts. An annular mounting boss 103 is disposed at the center of the interior of the outer shell 1. A turning rib 101 is disposed on the side of the outer shell 1. A mounting thread 102 is disposed on the side of the outer shell 1. Located above the screwing rib 101, the outer casing 1 is mounted on the wire cutting machine via the mounting thread 102. The screwing rib 101 assists in screwing the outer casing 1. A mounting ring 201 is provided on the outer side of the middle part of the wire guide cylinder 2. The mounting ring 201 is locked above the mounting boss 103. A water inlet hole 202 and a water outlet hole 203 are opened on the side of the wire guide cylinder 2. The water inlet hole 202 and the water outlet hole 203 are located on the upper and lower sides of the mounting ring 201, respectively. The outer end face of the mounting ring 201 contacts the inner wall of the outer casing 1. By limiting the diameter of the mounting ring 201, it is easy to position and install the wire guide cylinder 2. The lower outer side of the wire guide cylinder 2 The guide tube 2 has a sloping surface that is close to the wire insertion port at the bottom of the guide tube 2. The sloping surface connects to the water outlet 203. The sloping surface at the bottom of the guide tube 2 guides the output coolant, causing it to converge on the output tungsten-molybdenum wire for further cooling during cutting. The wear-resistant guide block 204 is made of diamond. A pressing cap 3 is fitted over the top of the guide tube 2. The lower end of the pressing cap 3 is pressed against the mounting ring 201. The upper end of the guide tube 2 protrudes from the upper surface of the pressing cap 3. A water injection hole 301 is provided on the upper surface of the pressing cap 3. There is a gap between the outer wall of the guide tube 2 and the inner wall of the outer shell 1. There is a gap between the outer wall of the tube 2 and the inner wall of the pressing cap 3.
