[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figure 1-6 A wire cutting device for workpiece processing includes a wire cutting device body, the wire cutting body includes a base plate 1, a first fixing plate 2, a top plate 3 and a molybdenum wire 29 for cutting the workpiece. The first fixing plate 2 is installed on the base plate 1, the top plate 3 is installed on the top of the first fixing plate 2, the molybdenum wire 29 is disposed between the top plate 3 and the base plate 1, and the side of the first fixing plate 2 is provided with an adjustment mechanism for adjusting the molybdenum wire 29.

[0035] The base plate 1 is provided with a pushing mechanism on its side for pushing the workpiece;

[0036] The adjustment mechanism includes a guide rail 4 mounted on the side of the first fixed plate 2. Two electric sliders 5 are slidably mounted on the guide rail 4. Mounting brackets 6 are mounted on the sides of each of the two electric sliders 5. First rollers 7 are rotatably mounted at the ends of both mounting brackets 6. A second roller 8 is rotatably mounted at the bottom of the upper mounting bracket 6. A molybdenum wire 29 passes sequentially around the upper first roller 7, the second roller 8, and the lower first roller 7. The two ends of the molybdenum wire 29 are vertical. By moving the two electric sliders 5 up and down on the guide rail 4, the height of the two mounting brackets 6 is adjusted. This allows the first roller 7 at the end of the upper mounting bracket 6 to be positioned in the middle of the C-shaped workpiece, and the first roller 7 at the end of the lower mounting bracket 6 to be positioned at the C-shaped workpiece. Below the C-shaped workpiece, the height of the two first rollers 7 can be easily adjusted according to the height of the C-shaped workpiece through the cooperation of two electric sliders 5 and guide rails 4. This facilitates the adjustment of the two first rollers 7 to a suitable height for C-shaped workpieces of different heights, improving the convenience of the device during use. The height of the two mounting brackets 6 can be arbitrarily adjusted by the two electric sliders 5, thereby allowing the height of the first rollers 7 at the end of the upper mounting bracket 6 to be adjusted according to the different heights of the C-shaped part of the C-shaped workpiece. This ensures that the first rollers 7 at the end of the upper mounting bracket 6 are within the C-shaped part of the C-shaped workpiece, facilitating wire cutting grooving of the C-shaped workpiece.

By tightening the locking nut 18, the locking nut 18 can move downward on the threaded rod 17 to push the second pressing plate 19 downward. Thus, the first pressing plate 13 and the second pressing plate 19 are used to press and fix the C-shaped workpiece. The C-shaped workpiece can be pressed and fixed between the first pressing plate 13 and the second pressing plate 19, which facilitates the fixing of the C-shaped workpiece.

[0038] As a technical optimization of the present invention, anti-slip rubber pads 14 are provided on the opposing surfaces of the first extrusion plate 13 and the second extrusion plate 19.

[0039] As a technical optimization of the present invention, the telescopic assembly includes a first electric telescopic rod 11 installed on the side of the second fixed plate 9 near the first fixed plate 2. The piston rod end of the first electric telescopic rod 11 is connected to a connecting plate 12. A first pressing plate 13 is installed on the side of the connecting plate 12. The connecting plate 12 facilitates the connection between the first pressing plate 13 and the piston rod of the first electric telescopic rod 11.

[0040] As a technical optimization of the present invention, a support column 15 is installed at the bottom of the first extrusion plate 13, and a sliding block 28 is installed at the bottom of the support column 15. A groove 16 is opened at the top of the bearing plate 23, and the sliding block 28 is slidably installed in the groove 16. The support column 15 can provide support for the first extrusion plate 13, thereby providing support for the C-shaped workpiece. The cooperation between the sliding block 28 at the bottom of the support column 15 and the groove 16 can provide guidance for the support column 15 when it moves laterally.

[0041] As a technical optimization of the present invention, the top plate 3 is equipped with an installation block 21, and a fixing block 24 is rotatably installed on the side of the installation block 21. A second electric telescopic rod 25 is installed on the side of the fixing block 24. The piston rod end of the second electric telescopic rod 25 is connected to an installation plate 26. A camera for capturing the working state of the molybdenum wire 29 is installed on the side of the second fixing plate 9 away from the first fixing plate 2. The display screen 10 is electrically connected to the camera. The camera can transmit real-time images of the C-shaped workpiece during wire cutting and grooving, which is convenient for workers to watch.

[0043] As a technical optimization of the present invention, a dust collection box 27 is installed on the side of the mounting plate 26. The dust collection box 27 is used to absorb the smoke and dust generated by the molybdenum wire 29 when cutting the workpiece.

[0044] As a technical optimization of the present invention, a dust collection connection port 20 is installed on the top of the top plate 3, and the dust collection connection port 20 is connected to the dust collection box 27 through a corrugated pipe.

[0045] A method of using a wire cutting device for workpiece processing according to the present invention includes the following steps:

[0046] S1: First, place the workpiece to be wire-cut between the first extrusion plate 13 and the second extrusion plate 19, rotate the locking nut 18 to move the second extrusion plate 19 down, and use the first extrusion plate 13 and the second extrusion plate 19 to clamp and fix the workpiece.

[0047] S2: Start the two electric sliders 5. The electric sliders 5 move up and down on the guide rail 4 to adjust the height of the two mounting brackets 6, so that the first roller 7 at the end of the upper mounting bracket 6 is in the middle area of ​​the workpiece.

[0048] S3: Start the first electric telescopic rod 11. The first electric telescopic rod 11 pushes the first extrusion plate 13, the second extrusion plate 19 and the clamped and fixed workpiece toward the molybdenum wire 29 to reach the preset processing position.

[0049] S4: At this point, the workpiece can be wire-cut using the wire cutting device itself.

[0050] When using this invention, if it is necessary to modify the contents of the appendix to the specification... Figure 7 When performing wire EDM grooving on the C-shaped workpiece shown, firstly, the C-shaped workpiece is placed on the first extrusion plate 13, so that the second extrusion plate 19 is above the C-shaped workpiece. Tighten the locking nut 18, and use the downward movement of the locking nut 18 on the threaded rod 17 to push the second extrusion plate 19 downward. Then, the first extrusion plate 13 and the second extrusion plate 19 are used to extrude and fix the C-shaped workpiece, which can be extruded and fixed between the first extrusion plate 13 and the second extrusion plate 19.

[0051] After the C-shaped workpiece is fixed, two electric sliders 5 are activated according to the height of the C-shaped workpiece and the location where the groove needs to be cut. The two electric sliders 5 move up and down on the guide rail 4 to adjust the height of the two mounting brackets 6, so that the first roller 7 at the end of the upper mounting bracket 6 is in the middle of the C-shaped workpiece, and the first roller 7 at the end of the lower mounting bracket 6 is below the C-shaped workpiece. Through the cooperation of the two electric sliders 5 and the guide rail 4, the height of the two first rollers 7 can be easily adjusted according to the height of the C-shaped workpiece, thus making it easy to adjust the two first rollers 7 to the appropriate height for C-shaped workpieces of different heights, improving the convenience of using this device.

[0052] After the height of the two first rollers 7 is adjusted, the first electric telescopic rod 11 is activated. The piston rod of the first electric telescopic rod 11 pushes the C-shaped workpiece, which is pressed and fixed between the first extrusion plate 13 and the second extrusion plate 19, to move laterally towards the molybdenum wire 29 of the wire cutting device body until the C-shaped workpiece is moved to the processing area of ​​the wire cutting device body and then stops. At this time, the wire cutting device body can be activated to perform wire cutting processing on the C-shaped workpiece. This device can be used to perform wire cutting grooving on the C-shaped workpiece, and the wire cutting grooving processing of the C-shaped workpiece can be completed in one go. The groove on the C-shaped workpiece can be processed without secondary processing, thereby reducing processing costs and processing time and improving processing efficiency.

[0053] Furthermore, when performing wire EDM grooving on C-shaped workpieces, motor 22 can be started. The output shaft of motor 22 drives the rotating shaft to rotate, thereby adjusting the angle of the fixed block 24. The rotation of the fixed block 24 drives the second electric telescopic rod 25 to rotate, adjusting the angle of the mounting plate 26, and thus adjusting the angle of the dust collection box 27. The dust collection connection port 20 can be connected to the external dust collection pipe, and the dust collection box 27 can collect and process the dust generated during wire EDM grooving of C-shaped workpieces. In addition, the camera mounted on the side of the mounting plate 26 can record the wire EDM process of C-shaped workpieces and display the processing process on the display screen 10. The operator can clearly see the wire EDM grooving process of C-shaped workpieces directly on the display screen 10, which facilitates real-time adjustment of the wire EDM device body to perform wire EDM processing on C-shaped workpieces, improving the convenience of this device when performing wire EDM processing on C-shaped workpieces.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
