Description

Technical Field

[0001] The utility model relates to the technical field of roller processing, in particular to an electrode insulation support and flow guide device used for an EDT texturing roller. Background Art

[0002] The electrodes used in EDT texturing rollers are consumables. When the electrode is consumed to 10mm, it needs to be replaced with a new electrode. When the electrode length is 80-150mm, the electrode length is long, resulting in a longer force arm length when the electrode texturing roller is used, which increases the force between the electrode sleeve and the electrode holder. When the electrode is long, the elastic deformation displacement of the electrode end is increased, resulting in electrode sleeve breakage, overlap short circuit between electrodes, loose electrode sleeve and electrode jitter, and electrode sleeve and electrode holder thread damage. The current treatment method is to continuously imprison the electrode sleeve and replace the new electrode sleeve and electrode holder, which increases the loss of accessories and maintenance time. At the same time, the abnormal swing of the electrode affects the quality of the roller surface texturing and requires re-grinding. The swing of a single electrode causes roller marks to easily appear on the roller surface, the roughness accuracy is reduced, and the roller texturing efficiency is reduced. The swing of the electrode sleeve and the loose electrode sleeve cause the overlap short circuit between the electrodes, which poses a fire risk in the texturing station. Summary of the Invention

[0003] The utility model provides an electrode insulation support and guide device used for an EDT texturing roller, which improves the roughness accuracy of the texturing roller, reduces surface defects of the texturing roller, maintenance time, electrode sleeve consumption and electrode seat loss, eliminates the electrode overlap short-circuit state, reduces damage to the circuit board, and eliminates the fire hazard of the texturing station caused by abnormal electrode jitter.

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0022] See Figure 1-2 , which are the front view and side view of the structure of the present invention. The present invention is an electrode insulation support and guide device for EDT texturing roller, comprising an electrode insulation support device, a guide plate 2, an electrode holder 11, a sealing device 6 and a texturing station box; the electrode insulation support device comprises an insulation support frame 1 and an adjustable position insulation device 3, the adjustable position insulation device 3 is symmetrically arranged on the left and right sides of the insulation support frame 1, 18 electrode through holes 4 are arranged on the insulation support frame 1, the depth of the electrode through holes is 3 to 5 mm, the position of the electrode through holes 4 corresponds to the position of the electrode 5 on the electrode holder 11, the diameter of the electrode through holes 4 is required to be symmetrical with the electrode 5 on the electrode holder 11, and the electrode through holes 4 are required to be symmetrical with the electrode 5 on the electrode holder 11. The inserted electrode 5 has a diameter clearance fit; the width of the insulating support frame 1 is 2 to 4 mm larger than the width of the electrode through-hole 4 after the upper and lower arrangements; the insulating support frame 1 is symmetrically provided with guide plates 2 inclined toward one side of the insulating support frame 1, and the guide plates 2 are inclined at a vertical angle of 30 to 45° relative to the support frame. The roughening station box 10 is arranged around the insulating support frame 1, and the electrode insulating support device, the electrode seat 11 and the guide plates 2 are arranged in the roughening station box 10, and the sealing device 6 is arranged on the side of the roughening station box 10 where the electrode 5 is exposed.

[0023] The length of the electrode 5 is 80 to 150 mm, the length of the electrode 5 on the sealing device 6 side exposed from the insulating support frame 1 is 8 to 20 mm, and the sealing device 6 faces the roller 7 when in use, and the sealing device 6 is larger than the length of the electrode 5 on the sealing device 6 side exposed from the insulating support frame 1.

[0024] Working principle: During installation, unplug the electrode 5, check whether the electrode sleeve is loose or bent, lock the electrode sleeve, put it into the electrode support device, align the 18 electrode holes on the electrode insulating support device with the 18 electrode sleeves on the electrode holder 11 where the electrode 5 is inserted, install the new electrode 5, and make the electrode 5 and the electrode insulating support device hole an interference fit. Move the electrode insulating support device to 10mm from the end of the electrode 5. The 18 electrodes 5 are relatively parallel with an error, and the through-hole 4 exerts an extrusion force on the electrode 5 to ensure that the support frame is firm and does not slide without external force. The width of the insulating support frame 1 is 2 to 4mm larger than the width of the electrode through-hole 4 after being arranged up and down, to ensure that the insulating support frame 1 is firm and avoid the insulating support frame 1 Excessive width blocks the electrolyte from entering the roughening position of the electrode 5. The insulating support frame 1 directly turns each group of 18 electrodes 5 into a main body, determines the position between each electrode 5, and cannot move without external force, directly avoiding the shaking, overlapping, and short circuit of a single electrode 5. The guide plate 2 guides the electrolyte, thereby increasing the flow of new electrolyte at the roughening position of the electrode 5. Adjustable position insulating devices 3 are set on the left and right sides of the insulating support frame 1. As the electrode 5 is consumed, the electrode support device will move from the adjustable position insulating device 3 to the electrode seat 11 side where the electrode 5 is installed. When the adjustable position insulating device 3 contacts the seal, it will automatically move backward by external force to avoid the support frame contacting the roller 7, ensuring that the support frame is in the correct position.

[0025] See Figure 3 During the texturing process, the roller 7 rotates, the texturing station box 10 moves forward, the sealing device 6 presses the roller 7 to prevent electrolyte leakage, the electrode 5 moves forward, the position of the insulating device 3 is adjusted to contact the seal, the insulating support 1 moves backward and keeps consistent with the sealing position, the electrode 5 moves forward to a position close to the roller surface of the roller 7, the electrolyte is sprayed out from the injection hole 9 of the oil pipe 8, and the guide plate 2 guides the new electrolyte to the position where the electrode 5 contacts the roller 7.
