Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and specifically relates to a numerically controlled fast wire electrical discharge wire cutting machine tool. Background Technique

[0002] With the expansion of industrial production scale and the development of manufacturing technology, wire cutting technology, as a kind of special processing technology, has been widely used in mechanical processing production due to its characteristics of high processing accuracy, high production efficiency, low power consumption, and low manufacturing cost. Especially in the mold processing industry, electrical discharge wire cutting technology is widely used in the processing of cold stamping dies and extrusion dies, changing the past processing mode of using separate dies and curve grinding, shortening the manufacturing cycle, reducing the manufacturing cost, and having high matching accuracy. Electrical discharge wire cutting machining (abbreviated as WEDM), sometimes also called wire cutting. Its basic working principle is to use a continuously moving thin metal wire (called the electrode wire) as the electrode to perform pulsed spark discharge on the workpiece to erode the metal and cut it into shape. Electrical discharge wire cutting technology is a kind of special processing. It is different from traditional processing technologies that need to use mechanical force and mechanical energy to cut, and mainly uses electrical energy to realize the processing of materials. Therefore, electrical discharge wire cutting technology is not restricted by the material properties and can process any materials with any hardness, strength, and brittleness, and occupies an important position in the current mechanical processing.

[0003] After retrieval, a patent with the Chinese patent publication number CN217529520U discloses a numerically controlled electrical discharge fast wire cutting machine tool, including a cutting machine tool body. A controller is installed at the lower end of the front surface wall of the cutting machine tool body. Fixed strips are fixed on both sides of the front surface wall of the cutting machine tool body and located on both sides of the controller. A chute is opened on the outer surface wall of the fixed strip. A fixing plate is fixed at the bottom end of the front surface wall of the cutting machine tool body. A compression spring is connected to the upper surface of the fixing plate. The top end of the compression spring is connected to a baffle. A sliding strip adapted to the chute is fixed on the side of the baffle facing the fixed strip. The above patent has the following deficiencies: When using this device to perform electrical discharge cutting on the workpiece, there will be electrical sparks splashing. These electrical sparks are accompanied by high temperatures. If they directly splash and touch the skin of the operator without any shielding, it will scald the operator, so there are great potential safety hazards. In view of this, we propose a numerically controlled fast wire electrical discharge wire cutting machine tool. Summary of the Invention

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] In the prior art, a patent with the Chinese patent publication number CN217529520U discloses a numerically controlled electric discharge high-speed wire cutting machine.

[0022] The inventor found that when using this equipment to perform electric discharge cutting on workpieces, electric sparks will splash. These electric sparks are accompanied by high temperatures. If they directly splash and touch the skin of the operator without an obstacle, it will burn the skin, so there is a great potential safety hazard.

[0023] Such as Figures 1-4As shown in the figure, a numerically controlled fast-wire electrical discharge wire-cutting machine includes a base 1, a glass enclosure 6, which is movably connected to the top of the base 1 through a clamping mechanism 5 for blocking the splashing of electrical sparks. The clamping mechanism 5 is arranged on the top of the base 1 for installing and fixing the glass enclosure 6. A back plate 2 is fixedly connected to the front of the base 1 to provide a supporting force for the clamping mechanism 5. A workbench 8 is fixedly connected to the top of the base 1 through the back plate 2 for placing the workpiece to be processed. A cleaning mechanism 7 is arranged on the top of the workbench 8, which can automatically clean the iron filings on the top of the workbench 8 after the workpiece processing is completed. A column 3 is fixedly connected to the front of the back plate 2, and a fast-wire cutting machine 4 is fixedly installed on the column 3.

[0024] To prevent the staff from being scalded by the splashing sparks, the clamping mechanism 5 includes an electric telescopic rod 51 and a slide rail 54. The back plate 2 is fixedly connected to the top of the base 1. The electric telescopic rod 51 is fixedly connected to the back of the back plate 2. A movable block 52 is fixedly connected to the rear end of the electric telescopic rod 51. Two movable rods 53 are hinged to the top of the movable block 52. The other ends of the movable rods 53 far from the movable block 52 are hinged to a slider 55. The movement of the slider 55 is limited by setting the slide rail 54. The slide rail 54 is opened on the top of the base 1. The slider 55 is slidably connected to the top of the slide rail 54. An anti-slip gasket 56 is fixedly connected to one side of the slider 55. A support plate 57 is fixedly connected to the top of the base 1. The bottom of the glass enclosure 6 is arranged between the anti-slip gasket 56 and the support plate 57. The glass enclosure 6 is clamped and fixed by setting the anti-slip gasket 56 and the support plate 57, thus preventing the staff from being scalded by the splashing sparks.

[0025] Furthermore, to clean the iron filings on the workbench 8, the cleaning mechanism 7 includes a permanent magnet 71, which is fixedly connected to the top of the movable block 52. A first chute 72 is opened at the bottom of the workbench 8. The permanent magnet 71 is slidably connected to the inside of the first chute 72. By setting the magnetic force of the permanent magnet 71 to drive the movement of an iron block 74, a second chute 73 is opened on the top of the workbench 8. An iron block 74 is slidably connected to the inside of the second chute 73. The iron block 74 is magnetically connected to the permanent magnet 71. A brush 75 is fixedly connected to the top of the iron block 74. The bottom of the brush 75 is slidably connected to the bottom surface of the workbench 8. Thus, the brush 75 automatically sweeps the iron filings on the surface of the workbench 8.

[0026] The working principle of the present utility model is as follows:

[0027] Before processing, first place the workpiece on the top of the workbench 8, then place the glass enclosure 6 between the anti-slip gasket 56 and the support plate 57. Subsequently, turn on the electric telescopic rod 51 to drive the movable block 52 to move forward. The forward movement of the movable block 52 drives the two sliders 55 to move to both sides under the limiting action of the slide rail 54 through the movable rod 53. The movement of the two sliders 55 to both sides drives the anti-slip gasket 56 to move to both sides to contact and fix the glass enclosure 6 and the support plate 57. Subsequently, turn on the high-speed wire cutting machine 4 to cut the workpiece. After cutting, repeat the above operation to move the movable block 52 backward while removing the glass enclosure 6 and taking out the workpiece. While the movable block 52 moves backward, the permanent magnet 71 moves backward within the range of the first chute 72. The backward movement of the permanent magnet 71 drives the iron block 74 to move backward under the limiting action of the second chute 73 through magnetic force. The backward movement of the iron block 74 drives the brush 75 to move backward while cleaning the iron filings on the workbench 8.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention.
