Description

Technical Field

[0001] This utility model relates to the field of electrical discharge cutting machine technology, specifically to a fully enclosed protective electrical discharge cutting machine. Background Technology

[0002] An electrical discharge machining (EDM) machine is a device that uses the high-temperature heat energy generated by electric spark discharge to process and cut materials. It is widely used in metal processing, mold manufacturing, precision parts processing and other fields. When using an EDM machine, a protective plate is installed on the outside of its processing platform to limit the processing range. For example, patent document CN212734511U discloses a new type of EDM machine. This cutting machine can open or close the protective cover by pushing or pulling, which is simple and convenient to operate. It does not affect the hoisting and transportation of the cutting material, and at the same time, it can provide good protection during cutting, prevent cutting splatter, and ensure the safety of use.

[0003] However, the outer protective cover of the aforementioned device is not completely sealed, and the front of the protective cover is open, which will still allow debris or cutting fluid to splash or enter the processing area during the processing, thus having an impact. Utility Model Content

A lifting rope is fixed at the top of the base plate. A rotating rod is rotatably provided at the lower end of the outer wall of the machine body. A winding wheel is fixedly fitted on the rod wall of the rotating rod. The upper end of the lifting rope passes through the guide ring and is wound and fixedly connected to the winding wheel.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a fully enclosed protective electric spark cutter.

[0025] This utility model provides, for example Figure 1-3 The fully enclosed protective EDM machine shown includes a body 1 and an outer cover 2 fitted on the upper part of the outer side of the body 1. A top rod 3 is fixed between the top of the body 1 and the outer cover 2. An annular inner cover 4 slides through the inner wall of the outer cover 2. A base plate 5 is fixed on both lower ends of the annular inner cover 4. Two symmetrically arranged guide rings 6 are fixed on the lower end of the outer wall of the outer cover 2. A hanging rope 7 is fixed on the top of the base plate 5. A rotating rod 8 is rotatably provided on the lower end of the outer wall of the body 1. A winding wheel 9 is fixedly fitted on the rod wall of the rotating rod 8. The upper end of the hanging rope 7 passes through the guide ring 6 and is wound and fixedly connected to the winding wheel 9. Mounting plates 19 are fixed on both lower ends of the body 1. Mounting rods 20 are rotatably provided on the outer wall of the mounting plates 19. A limiting wheel 21 is fixedly fitted on the rod wall of the mounting rod 20. The hanging rope 7 is driven by the limiting wheel 21.

[0026] The rod wall of the rotating rod 8 is provided with a winding positioning mechanism for limiting the winding position of the winding wheel 9. The winding positioning mechanism includes a guide frame 10, which is a U-shaped guide frame. The guide frame 10 is fixedly installed on the lower end of the outer wall of the machine body 1, and a rack 11 is slidably sleeved on the outside. A gear 12 is fixedly sleeved on the rod wall of the rotating rod 8. The rack 11 and the gear 12 are configured to cooperate.

[0027] In order to fix the position of the annular inner cover 4 after it rises, so as to facilitate the removal of workpieces inside the machine body 1, such as Figure 1-2 As shown, a push plate 13 is fixedly provided on the top of the rack 11, a support rod 14 is fixedly provided on the lower end of the outer wall of the machine body 1, a limiting plate 15 is rotatably sleeved on the rod wall of the support rod 14, a baffle 16 is provided in contact with the upper end of the outer wall of the limiting plate 15, a sliding hole is provided inside the baffle 16, a limiting block 17 is slidably passed through the sliding hole, the cross section of the limiting block 17 is T-shaped, the limiting block 17 is fixedly connected to the machine body 1, and a spring 18 is fixedly provided between the limiting block 17 and the top of the inner wall of the sliding hole.

[0028] Working principle: When the cutting machine is in use, the outer cover 2 is fixed to the top of the machine body 1 by the top rod 3, the annular inner cover 4 is slidably sleeved on the inner wall of the outer cover 2, and its lower end bottom plate 5 is connected to the winding wheel 9 by the suspension rope 7. The suspension rope 7 is guided and driven by the guide ring 6 and the limit wheel 21.

[0029] During normal cutting, the winding wheel 9 releases the lifting rope 7, and the annular inner cover 4 slides down the inner wall of the outer cover 2 under the action of gravity and fits against the bottom of the outer cover 2 to form a fully enclosed protective space to block electric sparks, cutting fluid and debris from splashing.

[0030] When the protection needs to be opened, the rotating rod 8 drives the winding wheel 9 to wind up the lifting rope 7, pulling the annular inner cover 4 to rise. At this time, the push plate 13 pushes the rack 11 to slide along the guide frame 10. The rack 11 meshes with the gear 12 to fix the rotating rod 8. At the same time, the limiting plate 15, under the action of the spring 18, locks the position of the rack 11 through the baffle 16 and the limiting block 17, realizing the lifting and positioning of the annular inner cover 4, which is convenient for the workpiece to be picked up and put down.

[0031] When the inner ring cover 4 needs to be lowered again, the baffle 16 can move longitudinally and separate from the limit plate 15 under the support of the limit block 17, so that the rack 11 can drive the push plate 13 to move in the opposite direction and move back to its original position. At this time, the inner ring cover 4 falls rapidly under its own gravity and continues to seal and protect the cutting machine.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
