Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to electrical discharge machine tools, specifically a lifting liquid tank type electrical discharge machine. Background Technology

[0002] An electrical discharge machining (EDM) machine is a type of machining equipment widely used in the manufacture of various metal molds and mechanical equipment. The EDM machine utilizes the electro-erosion effect generated by pulsed discharge between two electrodes immersed in a working fluid to remove conductive materials.

[0003] Traditional EDM machines generally employ a fixed oil tank structure. In this structure, the spindle lifting stroke is relatively long, resulting in low machining efficiency. Existing technology also includes EDM machines with a lifting oil tank, but in these cases, the oil tends to leak out after the tank is raised to its highest point. Therefore, an improved technology is urgently needed to solve the aforementioned problems in existing technologies. Utility Model Content

A fixing plate 25 is provided on the inner wall of the left side plate 3 and the right side plate 4. The two ends of the baffle 5 are connected to the left side plate 3 and the right side plate 4 respectively by the fixing plate 25 and bolts. The baffle 5 is used to ensure that the working fluid does not leak from the front of the boss 2. During installation, a sealing strip is installed at the connection between the baffle 5 and the fixed plate 25. A tongue-and-groove structure is provided at the bottom of the baffle 5 and the corresponding position of the boss 2 to prevent leakage of working fluid from the sides and bottom of the baffle 5. A lifting groove 6 is provided on the upper surface of the boss 2. An installation cavity 7 and a cavity 8 are provided at the lower part of the boss 2. A panel 16 is provided on the front side of the boss 2. A small door 17 is hinged to the panel 16 at the cavity 8. Opening the small door 17 facilitates the collection of waste slag from the slag discharge port 13. A vertically installed component is installed in the installation cavity 7. Hydraulic cylinder 9, lifting tank 6 with a return port 10 at the bottom, filter screen 11 on the inner wall of lifting tank 6 at the return port 10, several channels 12 are opened inside the boss 2, the bottom of the channels 12 are connected to the inside of lifting tank 6, and the top of the channels 12 are connected to the outside of boss 2. A slag discharge port 13 is provided at the bottom of lifting tank 6, the bottom of the slag discharge port 13 is located in cavity 8, and a sealing cover 19 is provided at the slag discharge port 13 to ensure that the working fluid does not leak from the slag discharge port during normal operation. 13. A working fluid storage tank 18 is provided on the side of the frame 1 away from the boss 2. The working fluid storage tank 18 is connected to the return port 10 through a pipe. After the working fluid enters the lifting tank 6, it flows back from the return port 10 to the working fluid storage tank 18. The working fluid is stored through the working fluid storage tank 18, and the working fluid is circulated through the pump inside the working fluid storage tank 18. Support feet 26 are provided at the bottom of both the frame 1 and the boss 2 to achieve overall lifting and support.

[0029] The top of the frame 1 is connected to the slide 21 via the linear motor stator, linear motor mover and linear guide rail. A crossbeam 22 is movably mounted on the upper surface of the slide 21 via the linear guide rail and lead screw pair. A main shaft 23 is mounted on the front side of the crossbeam 22 via the vertically arranged linear guide rail and lead screw pair. The main shaft 23 is movably mounted above the boss 2. A spray pipe mounting bracket 24 is provided on one side of the lower part of the main shaft 23 for mounting the working fluid spray pipe.

[0030] The lifting fluid tank 14 is movably installed inside the lifting tank 6. A worktable 15 is provided inside the lifting fluid tank 14. The piston rod of the hydraulic cylinder 9 is connected to the bottom of the lifting fluid tank 14. A guide sleeve 20 is provided between the mounting cavity 7 and the lifting tank 6. The guide sleeve 20 is filled with packing. The piston rod of the hydraulic cylinder 9 passes through the guide sleeve 20 and is tightly connected to the packing. The height of the top of the guide sleeve 20 is greater than the height of the filter screen 11. The bottom of the lifting fluid tank 14 is a grid structure. When the working fluid flows to the bottom of the lifting fluid tank 14, it passes through the grid structure and flows into the lifting tank 6, and is returned through the return port 9.

[0031] Installation method and operating principle: During operation, the workpiece is fixed on the worktable 15. Then, based on the workpiece's height, the hydraulic cylinder 9 drives the lifting fluid tank 14 to rise, thereby raising the worktable 15 and the workpiece. The linear motor stator and mover work together to drive the slide 21 to move laterally. The slide 21 then drives the crossbeam 22 to move back and forth via linear guides and a lead screw pair. The spindle 23 is raised and lowered via vertically arranged linear guides and a lead screw pair, thus achieving workpiece processing. Before operation, the spray pipe is installed on one side of the spindle 23 via the spray pipe mounting bracket 24. The spray pipe is connected to the working fluid storage tank 18 via a pump and pipeline. During the processing, the working fluid is sprayed onto the processing area of ​​the workpiece through the spray pipe. Most of the working fluid flows through the worktable 15 into the lifting fluid tank 14 and falls into the lifting tank 6 from the grid structure at the bottom of the lifting fluid tank 14. Then, it returns to the working fluid storage tank 18 through the return port 10. The debris is filtered through the filter screen 11. The working fluid is circulated by the pump in the working fluid storage tank 18. When too much waste accumulates in the lifting tank 6, the working fluid in the lifting tank 6 is first recovered, and then the small door 17 of the baffle 5 is opened to open the slag discharge port 13 and discharge the waste to complete the collection. This utility model has a reasonable structure. The frame 1, left side plate 3, right side plate 4 and baffle 5 form an oil tank. The oil tank is equipped with a liftable lifting fluid tank 14. The lifting fluid tank 14 is driven to rise and fall by the hydraulic cylinder 9. The height of the worktable 15 can be adjusted according to different workpieces, thereby reducing the lifting time of the spindle 23 and improving processing efficiency. Furthermore, the working fluid is prevented from overflowing by the shielding of the left side plate 3, right side plate 4 and baffle 5. The working fluid falling on the boss 2 flows into the lifting tank 6 through the channel 12, which is convenient for the collection of working fluid. The panel 16 is hinged to a small door 17 in the cavity 8. The bottom of the lifting tank 6 is provided with a slag discharge port 13. The small door 17 facilitates the collection of waste slag through the slag discharge port 13, which greatly improves convenience.
