Description

Technical Field

[0001] This utility model relates to the field of CNC electrical discharge machining technology, and in particular to a cross-type multi-station EDM machine. Background Technology

[0002] A spark discharge machine is a special processing equipment that uses the principle of electric spark discharge to process metal materials. It does not require mechanical force and can process various high-hardness, high-strength, and high-toughness metal materials, especially precision parts with complex shapes. It has wide applications in mold manufacturing, aerospace, automotive industry and other fields.

[0003] However, metal debris generated during processing circulates directly with the oil. When impurities adhere to the space between the electrode and the workpiece, they can alter the discharge gap, leading to abnormal discharge. This can cause burn marks or pits on the workpiece surface, or even dimensional deviations, failing to meet the precision requirements of precision molds or aerospace components. The continuous stirring of impurities in the oil can accelerate oil oxidation, leading to increased oil viscosity and decreased insulation performance. Utility Model Content

[0009] As a preferred embodiment of the cross-type multi-station EDM machine of this utility model, the base is fixedly connected to both sides of the base with ladders, and electrical boxes in contact with the ground are provided on both sides of the outer side of the ladders. A horizontal axis drive mechanism is fixedly connected to the inner wall of the column, a vertical axis drive mechanism is fixedly connected to the top of the horizontal axis drive mechanism, and a longitudinal axis drive mechanism that is slidably connected to the outer wall of the bullhead is fixedly connected to the outer wall of the vertical axis drive mechanism.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a cross-type multi-station EDM machine, including a base 1. Two columns 2 are fixedly connected to the top of the base 1. Two bullheads 12 are slidably connected to the top of one of the columns 2. A bullhead 12 slidably connected to the top of the other column 2 is arranged between the two bullheads 12. An oil tank 6 is fixedly connected to the outer wall of the base 1. Multiple oil inlets 13 are fixedly connected to the top of the oil tank 6. An oil outlet 17 is opened at the bottom of the inner wall of the oil inlet 13. A filter tube 16 is fixedly connected to the top of the oil outlet 17. A filter element 18 is installed on the outer wall of the filter tube 16. A handle 15 is fixedly connected to the top of the filter element 18.

[0024] The inner wall of the oil inlet 13 is provided with a connecting pipe 14 that communicates with the inner wall of another oil inlet 13. The outer wall of the base 1 is provided with multiple oil grooves 7, and the inner wall of the oil grooves 7 is slidably connected to the bottom end of the bull's head 12.

[0025] The outer wall of the oil outlet 17 is connected to the inner wall of the oil tank 7. A circular plate 19 is fixedly connected to the outer wall of the filter tube 16. Multiple arc-shaped permanent magnets 20 are fixedly connected to the inner wall of the circular plate 19. There is a gap between every two arc-shaped permanent magnets 20. An arc-shaped permanent magnet 20 with opposite polarity and corresponding to the arc-shaped permanent magnet 20 is embedded at the bottom of the filter element 18. Multiple balls 8 are installed at the bottom of the filter element 18. The balls 8 make it easy for the operator to rotate the handle 15. A groove is opened at the top of the circular plate 19 to roll and connect with the outer wall of the balls 8.

[0026] During use, the oil tank 6 is fixed to the outer wall of the base 1. The multiple oil inlets 13 at its top correspond to different processing areas and are used to receive the returned oil. After the oil enters the oil inlet 13, it will first flow to the filter pipe 16. The filter element 18 installed on the outer wall of the filter pipe 16 filters the oil, intercepting metal debris, impurities and other contaminants in the oil on the outside of the filter element 18. The clean oil after filtration flows into the oil tank 7 through the oil outlet 17, providing a clean working fluid for the processing of the bullhead 12.

[0027] When filter element 18 needs to be replaced, the operator holds handle 15 and rotates it. The ball bearing 8 at the bottom of filter element 18 will roll along the groove at the top of circular plate 19, making filter element 18 rotate smoothly. During this process, the arc-shaped permanent magnet 20 embedded at the bottom of filter element 18 and the arc-shaped permanent magnet 20 at the top of circular plate 19 will gradually separate due to relative sliding, and the magnetic attraction will disappear. Then, pull handle 15 upward to remove filter element 18 from filter tube 16. After replacing filter element 18, place it into oil inlet 13 along filter tube 16. As filter element 18 is lowered, the arc-shaped permanent magnet 20 on circular plate 19 and the arc-shaped permanent magnet 20 at the bottom of filter element 18 will attract and stick to each other due to opposite polarities. At the same time, ball bearing 8 will be inserted into the groove, completing the quick installation of filter element 18.

[0028] Example 2

[0029] Reference Figure 1 and Figure 2 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: both sides of the base 1 are fixedly connected to the climbing ladder 4, both sides of the climbing ladder 4 are provided with electrical boxes 9 that are in contact with the ground, the inner wall of the column 2 is fixedly connected to the horizontal axis drive mechanism 3, the top of the horizontal axis drive mechanism 3 is fixedly connected to the vertical axis drive mechanism 5, and the outer wall of the vertical axis drive mechanism 5 is fixedly connected to the longitudinal axis drive mechanism 11 that is slidably connected to the outer wall of the bull head 12.

[0030] The inner wall of column 2 is fixedly connected to a guide block 10 that is slidably connected to the bottom end of vertical shaft drive mechanism 5. The inner walls of horizontal shaft drive mechanism 3, vertical shaft drive mechanism 5 and longitudinal shaft drive mechanism 11 are all fixedly connected to telescopic cylinders and telescopic rods.

[0031] During use, the movement of the three heads 12 is independently controlled by their respective drive mechanisms. Their positions and movement trajectories can be adjusted individually according to processing requirements. When one head 12 is processing in a certain area, the other two heads 12 can work synchronously in other areas without interfering with each other, effectively avoiding collisions. If one head 12 malfunctions, only the drive mechanism corresponding to that head 12 needs to be stopped for repair, while the other two heads 12 can continue to work under the drive of their respective drive mechanisms. The entire equipment will not be shut down due to the failure of a single head 12, which significantly improves the working efficiency and production continuity of the equipment. The guide block 10 provides guidance for the movement of the vertical shaft drive mechanism 5, ensuring the accuracy of the head 12's movement.

[0032] The remaining structure is the same as that in Example 1.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
