[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] A typical embodiment of this utility model is as follows: Figure 1 As shown, an automatic push carbon arc gouging gun includes a gun body 2 and a carbon rod 1. The carbon rod 1 is inserted into the gun body 2 from the top and extends out from the bottom of the gun body 2. The gun body 2 is the outer shell of the carbon arc gouging gun, and the outer shell of the gun body 2 is covered with a layer of high-temperature resistant and insulating plastic material.

[0026] The gun body 2 is hollow inside and has a pushing device inside. The pushing device is fixed to the upper part of the inner wall of the gun body 2 by a pushing device bracket 3. The pushing device bracket 3 is a cylindrical hollow tube, and there are two of them, which are symmetrically installed on the inner wall of the gun body 2.

[0027] like Figure 2 As shown, a first spring 14 is provided inside the push device bracket 3, and a steel pipe 16 is provided at one end of the push device bracket 3 away from the inner wall of the gun body 2. One end of the steel pipe 16 is inserted into the push device bracket 3 and compresses the first spring 14, so that the steel pipe 16 can move inside the push device bracket 3.

[0028] A second spring 15 is provided between the steel pipe 16 and the pusher bracket 3. Baffles are installed on both sides of the second spring 15 to prevent the spring from falling out. The second spring 15 is in a compressed state. The distance between the two pushers can be adjusted by the first spring 14 and the second spring 15 to accommodate carbon rods 1 of different diameters.

[0029] The pushing device includes a roller bracket 19 and a roller 18, which are fixed to the end of the steel pipe 16 away from the pushing device bracket 3. The roller bracket 19 is U-shaped, and the roller 18 is provided with roller shafts 17 at both ends. The roller shafts 17 are rotatably connected to the two ends of the roller bracket 19.

[0030] The roller support 19 is also equipped with a motor 13. The output shaft of the motor 13 is fixedly connected to the roller shaft 17 at one end of the roller 18, so that the motor 13 drives the roller 18 to rotate.

[0031] Roller 18 is mounted on roller bracket 19. The outer surface of roller 18 is a concave ellipse and the material is high temperature resistant, insulating, wear resistant and elastic polytetrafluoroethylene, which can be used for various carbon rods 1.

[0032] A baffle plate 4 is provided below the pushing device. The baffle plate 4 is fixedly connected to the inner wall of the gun body 2. The baffle plate 4 is provided to prevent gas from entering the pushing device above, and to protect the pushing device from burning or contaminating it.

[0033] The gun body 2 is also equipped with a conductor 9, which is located in the lower part of the gun body 2. The conductor 9 is made of copper and has an inverted conical structure. Its upper end is fixed to the inner wall of the gun body 2 and connected to the power line 7. Its lower end is divided into four equal parts, and the lower end of each part presents an arc-shaped valve tube. One side of the valve tube is connected to the third spring 11. The third spring 11 is fixed to the inner wall of the gun body 2 through the spring support 10.

[0034] Under the elastic force of the third spring 11, the four valves of the conductor 9 are kept in contact with the carbon rod 1 at all times, ensuring the conductivity of the carbon rod 1.

[0035] One end of the third spring 11 is fitted inside the spring support 10, and the other end is connected to the valve tube of the conductor 9. The valve tube can be used for carbon rods 1 of various specifications. Under the elastic force of the spring, the conductor 9 and the carbon rod 1 are always in contact, ensuring the conductivity of the carbon rod 1.

[0036] The gun body 2 has a gun head 12 at its bottom. The gun head 12 is a ring-shaped structure with multiple small holes with a diameter of 20mm, which can be used to blow away the molten liquid metal with compressed air.

[0037] A handle 20 is provided on one side of the gun body 2. The handle 20 is made of a heat-insulating and insulating material. The handle 20 is hollow and connected to the interior of the gun body 2. A power cord 7 and an air pipe 8 are connected to the end of the handle 20 away from the gun body 2. The power cord 7 supplies power to the motor 13 via a conductor 9. The air pipe 8 supplies compressed air to the gun body 2.

[0038] The handle 20 is equipped with a switch 5, which is electrically connected to the motor 13. The switch 5 can control the forward and reverse rotation of the motor 13, which can not only use the motor 13 to feed the carbon rod 1 downward, but also flexibly adjust the feeding length of the carbon rod 1.

[0039] The handle 20 is also covered with an insulating sleeve 6, which can play a role in preventing slipping, insulating and heat insulation.

[0040] Working principle

[0041] When using it, first turn on the power and air pipe, and feed the carbon rod from the top of the gun body into the gun body. Turn on the switch to make the motor drive the roller, so that the carbon rod moves downward. When the carbon rod comes into contact with the conductor, it becomes electrified. Adjust the length of the carbon rod according to the part of the weld to be operated, and continue the operation.

[0042] During operation, the carbon rod can be stopped and replaced at any time according to the actual situation on site. The carbon arc gouging gun is suitable for carbon rods of various specifications. When a carbon rod is used up, carbon rods can be fed directly from the top without delaying the use.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
