Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See attached document Figures 1-5This utility model provides an EDM (Electrical Discharge Machining) CNC wire cutting machine with easy-to-adjust direction, including a processing groove 100. A fixed base 110 is fixed to the rear end of the outer wall of the processing groove 100. A hydraulic telescopic column 120 is installed at the top end of the outer wall of the fixed base 110. An upper fixing component for fixing the electrode wire is installed at the top end of the outer wall of the hydraulic telescopic column 120. The upper fixing component includes a first horizontal plate 130, which serves as the main support. The first horizontal plate 130 is fixed to the top end of the outer wall of the hydraulic telescopic column 120. A pulse power supply 140 is fixed to the rear side of the top end of the outer wall of the first horizontal plate 130. The pulse power supply 140 and the pulse generator 150 cooperate to generate electromagnetic pulses on the electrode wire, so that the electrode wire can cut the metal workpiece through the electromagnetic pulses. The pulse generator 150 is rotatably fixed to the front end of the outer wall of the first horizontal plate 130 via a rotating shaft. The bottom end of the outer wall of the pulse generator 150... A first fixed electrode 151 is fixed to fix the upper end of the resistance wire. The first fixed electrode 151 can fix the upper end position of the electrode wire and can cooperate with the electrode wire fixing cylinder 350 to make the electrode wire carry electromagnetic pulses. A driven gear 152 is fixed to the outer wall of the rotating shaft. A drive motor 153 is fixed to the front end of the outer wall of the first horizontal plate 130 and located on one side of the rotating shaft. A drive gear 154 is fixed to the output end of the drive motor 153. One side of the outer wall of the drive gear 154 meshes with the outer wall side of the driven gear 152. When the drive motor 153 is powered on, it can drive the drive gear 154 to rotate in both directions. When the drive gear 154 rotates, it can drive the driven gear 152 and the rotating shaft to rotate together, so that the pulse generator 150 and the first fixed electrode 151 can rotate. The rotating shaft is rotatably connected to the front end of the outer wall of the first horizontal plate 130.

[0024] The bottom of the inner wall of the processing tank 100 is provided with a lower fixing component for fixing the electrode wire. The lower fixing component includes an arc-shaped guide rail 200. The bottom of the outer wall of the arc-shaped guide rail 200 is fixedly connected to the bottom of the inner wall of the processing tank 100 through a guide rail fixing block 210. Arc-shaped guide grooves 220 are opened at the bottom of the inner wall side of the arc-shaped guide rail 200. A second horizontal plate 300 is provided at the inner wall side of the arc-shaped guide rail 200. The second horizontal plate 300 mainly drives the electrode wire fixing cylinder 350 to slide left and right on the inner wall of the arc-shaped guide rail 200, thereby cooperating with the rotating pulse generator 150 to adjust the direction of the electrode wire. The center of the bottom of the outer wall of the second horizontal plate 300 is... A base 310 is fixed at the base. Guide arc strips 330 are fixed at the front and rear ends of the outer wall of the base 310, corresponding to the positions of the arc-shaped guide groove 220. The outer wall of the guide arc strips 330 is slidably connected to the inner wall of the arc-shaped guide groove 220. The guide arc strips 330 are designed to cooperate with the arc-shaped guide groove 220 to ensure that the second horizontal plate 300 moves along the trajectory of the arc-shaped guide rail 200, and to prevent the second horizontal plate 300 from detaching from the arc-shaped guide rail 200. A strip-shaped groove is formed at the bottom of the outer wall of the base 310. A moving wheel 320 is mounted on the inner wall of the strip-shaped groove via a pivot. The moving wheel 320 is designed to facilitate the movement of the second horizontal plate 300 along the arc-shaped guide rail. The inner wall of the second horizontal plate 300 is moved. Two fixing bolts 340 are threaded onto the top two sides of the outer wall of the second horizontal plate 300, located on both sides of the base 310. After the second horizontal plate 300 is moved to the correct position, the two fixing bolts 340 can be tightened using a tool. The bottom end of the fixing bolts 340 abuts against the inner wall side of the arc-shaped guide rail 200, thus fixing the position of the second horizontal plate 300. An electrode wire fixing cylinder 350 is fixed at the center of the top of the outer wall of the second horizontal plate 300. An electrode wire fixing clamp 351 is fixed to one side of the inner wall of the electrode wire fixing cylinder 350 via a fixing shaft. The inner wall of the electrode wire fixing cylinder 350, located on both sides of the base 310, is fixed to the electrode wire fixing clamp 351. An electrode wire moving clamp 352 is provided on one side of the clamping block 351. The outer wall of the electrode wire moving clamp 352 is threadedly connected to the inner wall of the electrode wire fixing cylinder 350 through an adjusting stud 353. Specifically, the operator can insert the bottom end of the electrode wire into the electrode wire fixing cylinder 350, and then rotate the adjusting stud 353 to move the electrode wire moving clamp 352 to cooperate with the electrode wire fixing clamp 351 to clamp the bottom end of the electrode wire, ensuring that the bottom end of the electrode wire will not come off during use. The electrode wire fixing clamp 351 and the electrode wire moving clamp 352 can be made of copper alloy or other metal alloy materials.

[0025] The usage process of this utility model is as follows: Those skilled in the art can assemble the device according to the above description, then connect all electrical equipment to external power supply and connect it to the controller so that personnel can control the operation and stop of the device;

[0026] After completion, personnel can determine the setting direction of the electrode wire according to requirements. Specifically, personnel can first place a soft rope between the first fixed electrode 151 and the electrode wire fixing cylinder 350 to temporarily replace the electrode wire. Then, the fixing bolt 340 can be loosened, and the drive motor 153 can be energized to slowly drive the drive gear 154 to rotate. This allows the drive gear 154 to drive the driven gear 152, pulse generator 150, and first fixed electrode 151 to rotate. Simultaneously, personnel can hold the second horizontal plate 300 and slide it along the outer wall of the arc-shaped guide rail 200, coordinating with the rotating first fixed electrode 151 to adjust the device to the desired position. After adjusting the angle, the operator can tighten the fixing bolts 340 to fix the position of the second horizontal plate 300. Then, the operator can remove the soft rope and fix the upper and lower ends of the electrode wire to the first fixed electrode 151 and the electrode wire fixing cylinder 350 (the fixing method between the electrode wire and the first fixed electrode 151 has been disclosed in the existing EDM CNC wire cutting machine). Then, the operator can place the product to be cut on the placement rack set on the upper end of the inner wall of the processing tank 100. Then, the electromagnetic pulse can be released to the electrode wire through the pulse power supply 140 and the pulse generator 150, so that the electrode wire can cut the product.

[0027] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
