Description

Technical Field

[0001] The utility model relates to the technical field of metal punching, in particular to a punching device for metal product processing. Background Art

[0002] There are many ways to punch holes in metal products, depending on the material, depth and diameter of the holes. Common methods include drilling, oxygen cutting, cold stamping, laser cutting and pulse cutting. The rotation target can also be changed. In order to protect the drill bit or to be able to check with the naked eye, holes can also be punched by rotating the metal product at high speed.

[0003] In conventional metal drilling, there are often problems such as weak drilling, deviation of the drill center, high wear of the drill bit and high temperature of the drill bit. Therefore, some experienced operators will spray soy sauce, pigment mixture or some grinding fluid on the surface of the object to be punched when drilling, so as to reduce the above problems. However, manual spraying will cause a certain degree of waste of the grinding fluid. For this reason, we provide a punching device for metal product processing to solve the above problems.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-7 As shown, the utility model provides a technical solution: a punching device for metal product processing, comprising a base 1, a hydraulic rod 2 is installed on the outer surface of the base 1, a sealing box 3 is fixedly connected to the outer surface of the hydraulic rod 2, a movable sleeve 4 is fixedly connected to the inner top wall of the sealing box 3, a sealing plug 5 is slidably connected to the inner wall of the movable sleeve 4, two electromagnets 6 are installed on the outer surface of the movable sleeve 4, a drill bit 7 is connected to the bottom surface of the sealing box 3 by screws, a cavity 8 is opened inside the drill bit 7, and a nozzle 9 is opened on the inner side of the drill bit 7. When the two electromagnets 6 are alternately energized, the iron sealing plug 5 can be driven to move up and down in the movable sleeve 4. When the sealing plug 5 moves up and down, the internal abrasive of the movable sleeve 4 located below the sealing plug 5 can be pushed into the cavity 8 of the drill bit 7 through the movable sleeve 4. When the sealing plug 5 moves up and down, the pressure in the cavity 8 is continuously increased with the repeated movement of the sealing plug 5, and finally the abrasive can be sprayed near the position directly below the drill bit 7 through the nozzle 9, thereby improving the use efficiency of the abrasive, reducing the waste of the abrasive, and solving the problem that manual spraying will cause a certain degree of waste of the grinding liquid.

[0027] The outer surface of the movable sleeve 4 located between the two electromagnets 6 is fixedly connected with an isolation plate 10, and the outer surface of the isolation plate 10 is fixedly connected to the inner wall of the sealing box 3. The isolation plate 10 is a composite material and is mainly divided into three layers. The materials are neodymium iron boron (NdFeB), copper plating and aluminum foil layer. The three interlayers are wrapped by nickel-iron alloy, which can effectively isolate the mutual electromagnetic fields generated by the two electromagnets 6.

[0028] The bottom end of the movable sleeve 4 is fixedly connected to the annular sleeve 11, and a rubber sheet 12 is installed on the bottom surface of the annular sleeve 11. A sealing sheet 24 is fixedly connected to the bottom surface of the annular sleeve 11. The outer surface of the rubber sheet 12 is in close contact with the outer surface of the rubber sheet 12. When the internal air pressure of the movable sleeve 4 above the annular sleeve 11 is lower than that below the annular sleeve 11, the annular sleeve 11 will be blocked by the rubber sheet 12. At the same time, the sealing sheet 24 is also composed of rubber and can provide good sealing. When the internal air pressure of the movable sleeve 4 above the annular sleeve 11 is higher than that below the annular sleeve 11, the high-pressure gas will push the rubber sheet 12 into the annular sleeve 11 below.

[0029] A rubber nozzle 13 is fixedly connected to the bottom end of the movable sleeve 4, and the outer surface of the rubber nozzle 13 is in close contact with the inner wall of the drill bit 7. A mounting ring 14 is fixedly connected to the outer surface of the drill bit 7. A sealing ring 15 is inlaid on the inner wall of the mounting ring 14. The mounting ring 14 can prevent the sealing ring 15 from being separated from its original position. A sealing ring 2 16 is inlaid on the inner wall of the drill bit 7. The outer surfaces of the sealing ring 15 and the sealing ring 2 16 are fixedly connected to the outer surface of the rubber nozzle 13. The sealing ring 15 and the sealing ring 2 16 can seal the gap between the rubber nozzle 13 and the inner wall of the drill bit 7, so that the high-pressure gas or liquid inside the movable sleeve 4 can all enter the inside of the drill bit 7.

[0030] A conduit 17 is fixedly connected to the inner side of the movable sleeve 4, and the outer surface of the conduit 17 is fixedly connected to the inner side of the sealing box 3. The conduit 17 is located inside the movable sleeve 4 and is installed with a one-way valve. The one-way valve can ensure that the liquid inside the conduit 17 always flows in one direction, preventing the liquid inside the movable sleeve 4 from flowing back into the interior of the conduit 17.

[0031] A motor 18 is installed on the outer surface of the base 1, and a rotating rod 19 is fixedly connected to the output end of the motor 18, and a clamping plate 20 is fixedly connected to the top of the rotating rod 19. The outer surface of the clamping plate 20 is rotatably connected to a main control board 23, and the outer surface of the main control board 23 is rotatably connected to a clip 21. The inner wall of the clip 21 is threadedly connected to a threaded rod 22. The threaded rod 22 can drive the clip 21 when rotating. When a single clip 21 moves, all the clips 21 can be driven to move in relative directions through the main control board 23, so that the object can be clamped. The motor 18 can drive the clamping plate 20 to rotate at high speed through the rotating rod 19, thereby driving the punched metal parts to move.

[0032] Working principle: when the device needs to be used, first connect the catheter 17 to the prepared grinding liquid, connect the electromagnet 6, the motor 18 and the hydraulic rod 2 to the power supply, and fix the object to be polished on the clamping plate 20 through the clip 21, then turn on the motor 18 and the electromagnet 6. After the motor 18 is turned on, it can drive the object to be polished to rotate at a high speed. The two electromagnets 6 are repeatedly energized to drive the sealing plug 5 to move up and down. When the sealing plug 5 moves up and down, the grinding liquid in the catheter 17 can be pumped into the movable sleeve 4, and enters the cavity 8 in the drill bit 7 under the push of the sealing plug 5, and finally sprayed from the nozzle 9 onto the surface of the object to be polished, and then start the hydraulic rod 2 to make the drill bit 7 close to and contact the surface of the object to be polished to achieve drilling. During this period, since the spray position of the nozzle is below the drill bit 7, when the drill bit 7 drills into the inner side of the object to be polished, the sprayed grinding liquid can still always splash on the friction point between the drill bit 7 and the object to be polished.
