Description

Technical Field

[0001] This utility model belongs to the field of wire EDM technology, and in particular relates to a resin filter for slow wire EDM processing fluid. Background Technology

[0002] In wire EDM, lubrication and chip removal by the machining fluid are indispensable. Existing machine tools use machining fluid equipment that only purifies and filters the cutting fluid, playing a role in chip removal and lubrication. Slow wire EDM uses purified water as the machining fluid. After passing through a primary filter, the fluid then passes through a resin filter to adsorb metal ions. Current resin filters allow the machining fluid to pass through the entire resin filter element. Over long-term use, this results in high usage at the inlet end and low usage at the outlet end, failing to fully utilize the resin filter element's adsorption capacity for metal ions. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to improve a slow wire EDM resin filter that can ensure the repeated use of resin filter elements in various positions within the resin carrier.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a slow wire EDM fluid resin filter, comprising an outer cylinder, a base, a tray, a resin carrier, a water injection pipe, an upper carrier plate, a lower carrier plate, a telescopic corrugated pipe, a sealing plate, a connector, a guide rod, and a diverter. The resin carrier is placed inside the outer cylinder. The base is sealed and fixedly installed at the bottom of the outer cylinder by a flange structure.

[0007] A guide sleeve is fixedly installed on the download board, and the guide sleeve is slidably fitted onto the guide rod.

[0008] Compared with the prior art, the advantages of this utility model are: This filter controls the reciprocating motion of the water injection pipe and the distributor head, so that the processing fluid sprayed by the distributor head can circulate and contact with the resin at different heights in the annular resin containment area, so that the resin at different heights can be fully utilized, improving the resin utilization rate. At the same time, it improves the purification effect of the processing fluid adsorbing metal ions.

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figures 1 to 3The slow wire EDM fluid resin filter shown includes an outer cylinder 1, a base 2, a tray 21, a resin carrier 3, a water injection pipe 4, an upper carrier plate 51, a lower carrier plate 52, a telescopic corrugated pipe 53, a sealing plate 6, a connector 61, a guide rod 7, and a diverter 8. The resin carrier 3 is placed inside the outer cylinder 1. The base 2 is sealed and fixedly installed at the bottom of the outer cylinder 1 by a flange structure. The tray 21 is fixedly installed on the inner wall of the base 2 by a connecting plate 22. The lower part of the resin carrier 3 is placed... On tray 21, the upper part of the resin carrier 3 presses against the top of the inner wall of the outer cylinder 1. The connecting plate 22 has through holes arranged in a ring array. The resin carrier 3 has a mesh structure and a blind hole 30 in the middle. The resin carrier 3 also has a ring-shaped resin receiving area 31. The upper carrier plate 51 and the lowering plate 52 are respectively fixedly installed at the upper and lower ends of the telescopic corrugated pipe 53. The lowering plate 52 is fixedly installed on the top of the outer cylinder 1. The four guide rods 7 are arranged in a rectangular pattern. The upper plate 51 is slidably mounted on the guide rod 7, and the water injection pipe 4 is slidably and sealedly mounted on the top of the outer cylinder 1. The lower part of the water injection pipe 4 is placed in the blind hole 30, and the upper part of the water injection pipe 4 is placed in the telescopic corrugated pipe 53. The top of the water injection pipe 4 is also sealed and fixedly connected to the lower plate 52. The middle part of the water injection pipe 4 has a water passage hole 41. The diverter head 8 is sealed and fixedly mounted on the bottom of the water injection pipe 4. The diverter head 8 has diverter holes 81 connected to the water passage hole 41 in a ring array. The sealing plate 6 is sealed and fixedly mounted on the top of the water injection pipe 4. The sealing plate 6 is fixedly mounted with a connector 61. The connector 61 is fixedly connected to the execution end of the linear drive mechanism. The linear drive mechanism is an electric push rod. The connector 61 is fixedly connected to the execution rod of the electric push rod. The water injection pipe 4 is sealed and fixedly mounted with a water inlet pipe 42. The bottom of the telescopic corrugated pipe 53 is provided with a drain pipe 54, which is connected to the water collection tank.

[0015] The top surface of the tray 21 is provided with a positioning groove that matches the bottom of the resin carrier 3. The bottom of the resin carrier 3 is embedded in the positioning groove on the top surface of the tray 21. The positioning groove limits the bottom of the resin carrier 3, which can improve the stability of the resin carrier 3 assembly structure. The top of the resin carrier 3 is provided with a 0.5-1cm rubber ring. The rubber ring is pressed against the top of the inner wall of the outer cylinder 1, which can prevent the resin carrier 3 containing resin from shaking during actual use.

[0016] A reinforcing plate 72 is fixedly installed on the top of the four guide rods 7. The reinforcing plate 72 is provided with an opening for the sealing plate 6 to pass through, so as to improve the stability of the overall structure of the four guide rods 7, and thus improve the straightness of the download plate 52 when it moves up and down along the guide rods 7.

[0017] A guide sleeve 71 is fixedly installed on the download plate 52. The guide sleeve 71 is slidably sleeved on the guide rod 7. The thickness of the download plate 52 is only 0.8-1.3cm. Through the guiding effect of the guide sleeve 71, the straightness of the download plate 52 when moving up and down along the guide rod 7 can be improved.

[0018] Resin for adsorbing metal ions is filled in the annular resin accommodating area 31 as a resin filter element. The processing fluid is pressurized by a pressure pump and then treated by a primary filter. It is then injected into the water passage hole 41 of the water injection pipe 4 through the water inlet pipe 42. The electric push rod is activated to drive the assembly of the sealing plate 6, the download plate 52, the telescopic corrugated pipe 53, the water injection pipe 4 and the diverter head 8 to move up and down reciprocally. Under pressure, the processing fluid is sprayed outward in an annular shape through the diverter hole 81. Because the diverter hole 81 moves up and down reciprocally, the processing fluid sprayed outward through the diverter hole 81 can circulate and contact with the resin at different heights in the annular resin accommodating area 31, so that the resin at different heights can be fully utilized. The processing fluid after being adsorbed by the resin flows out through the through hole on the connecting plate 22 and is then collected uniformly through the opening of the base 2. When the processing fluid leaks due to wear of the sealing ring between the water injection pipe and the top of the outer cylinder, a small amount of processing fluid enters the expansion bellows 53 and is then discharged through the drain pipe 54 to the water tank for unified collection, so as to avoid the processing fluid accumulating in the expansion bellows 53 and becoming uncompressible.
