Description

Technical Field

[0001] The utility model relates to the technical field of electric spark wire cutting machines, and more specifically, to an auxiliary device of the electric spark wire cutting machine. Background Art

[0002] Wire EDM technology is a type of special processing that mainly uses electrical energy to process materials. Wire EDM technology is not limited by material properties and can process materials of any hardness, strength, and brittleness. The basic working principle of wire EDM processing is to use a continuously moving thin metal wire as an electrode to perform pulse spark discharge to erode metal and cut the workpiece into shape.

[0003] After searching, the utility model patent with announcement number CN209736800U discloses an auxiliary device for an electric spark wire cutting machine, and the key points of its technical solution are as follows: it includes: a workbench installed on the electric spark wire cutting machine; a mounting block slidably connected to the bearing surface of the workbench; and a scraper installed on the mounting block and in contact with the bearing surface of the workbench, the mounting block is equipped with an adjustment component for adjusting the height of the scraper, and the workbench is equipped with a driving component for driving the mounting block to slide on the workbench. When the electric spark wire cutting machine is in use, the metal particles that fall into the electric spark wire cutting machine can be collected and concentrated, so that the operator can clean them up at one time.

[0004] However, the above patent still has the following shortcomings: metal particles will splash when the electric spark wire cutting machine is used, which is not convenient to block the splashing metal particles and may cause danger to the staff; in addition, after the metal particles are pushed to one side, the staff still needs to take out the metal particles, which is not convenient to use. For this reason, we propose an auxiliary device for the electric spark wire cutting machine. Utility Model Content

[0028] For details, please refer to Figures 1 to 5 The chip suction mechanism 8 includes an air suction pump 11 fixedly mounted on the outside of the U-shaped frame 7 and a chip suction cover 12 fixedly sleeved on the inside of the U-shaped frame 7. The input end of the air suction pump 11 extends to the inner cavity of the collecting chamber 10, and the end of the chip suction cover 12 extends to the inner cavity of the collecting chamber 10. The inner cavity of the collecting chamber 10 is provided with a filter screen 13.

[0029] In this embodiment, an air pump 11 is used to generate suction for the chip hood 12. When the U-shaped frame 7 and the chip hood 12 are driven by the electric push rod 6 to move into contact with the frame 1, the suction force of the chip hood 12 is used to collect waste chips on the top surface of the frame 1 into the inner cavity of the collection chamber 10.

[0030] For details, please refer to Figures 3 to 5 A plug 14 is sleeved on one end of the inner cavity of the collecting chamber 10, a pull ring 17 is fixedly connected to the outer side of the plug 14, a pull rod 15 is fixedly connected to the inner side of the plug 14, one end of the pull rod 15 extends to the inner cavity of the collecting chamber 10 and is fixedly connected to a scraper 16, and the side of the scraper 16 is in contact with the side of the filter screen 13.

[0031] In this embodiment, the end of the collecting chamber 10 is blocked by the plug 14, and the scraper 16 is used to pull the waste collected in the inner cavity of the collecting chamber 10 so as to clean out the waste in the collecting chamber 10.

[0032] For details, please refer to Figure 3 A controller 18 is fixedly mounted on the outer side of the U-shaped frame 7 .

[0033] In this embodiment, the controller 18 is used to control the electric push rod 6 and the air pump 11. At the same time, the controller 18 is electrically connected to the electric push rod 6 and the air pump 11 respectively. In addition, the electric push rod 6, the air pump 11 and the controller 18 can be connected to an external power supply through electrical wires.

[0034] For details, please refer to Figure 4 The inner side surface of the elastic cloth 9 is flush with the inner wall of the collecting groove 5.

[0035] In this embodiment, it is ensured that the waste debris blocked by the elastic cloth 9 can fall smoothly into the collecting trough 5 .

[0036] For details, please refer to Figure 2 The side of the U-shaped collecting box 4 is fitted with the inner wall of the return groove 2, and the two U-shaped collecting boxes 4 are in contact with the ends of the two elastic cloths 9.

[0037] In this embodiment, the U-shaped collecting box 4 is ensured to be stably placed in the return groove 2 to prevent waste chips generated during cutting from falling into the gap in the return groove 2. In addition, the contact between the two U-shaped collecting boxes 4 and the two elastic cloths 9 ensures that the waste chips can be completely collected and blocked.

[0038] Working principle: When in use, first place the material to be cut on the frame 1, and place two U-shaped collecting boxes 4 in the return groove 2, start the electric push rod 6 to drive the U-shaped frame 7 to move up, use the U-shaped frame 7 to drive the elastic cloth 9 to stretch, and then start the wire cutting head 3 to cut the material. At the same time, the waste chips generated by the cutting fall to the top surface of the frame 1, and a part of the splashing waste chips are blocked by the elastic cloth 9. The blocked waste chips fall into the collecting groove 5 and are collected. Then, after the cutting is completed, start the electric push rod 6 to drive the U-shaped frame 7 to move down, so that the chip suction cover 12 on the inner side of the U-shaped frame 7 contacts the top surface of the frame 1. At this time, the cut material can be removed, and the suction pump 11 is started to move the air into the inner cavity of the collection chamber 10. By exhausting air, negative pressure is generated in the inner cavity of the collection chamber 10, so that the chip suction hood 12 generates suction. The suction force of the chip suction hood 12 is used to suck the waste chips dropped from the top surface of the frame 1 into the inner cavity of the collection chamber 10, and the filter screen 13 in the inner cavity of the collection chamber 10 is used to retain the waste chips in the inner cavity of the collection chamber 10. Finally, after cutting multiple materials, the U-shaped collection box 4 is taken out from the inner cavity of the return groove 2, and the waste chips in the collection groove 5 on the U-shaped collection box 4 are cleaned. In addition, the pull ring 17 is held to pull the plug 14 out of the collection chamber 10. When the plug 14 is pulled out, it drives the pull rod 15 and the scraper 16 to move in the inner cavity of the collection chamber 10, and the scraper 16 is used to scrape out the waste chips in the inner cavity of the collection chamber 10, so as to clean the waste chips collected in the collection chamber 10.

[0039] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
