[0002] During the production of metal forgings, an oxide skin often forms on the surface, and this oxide skin needs to be removed to improve the quality of the forgings. To achieve the skin-removing effect, sandblasting is often used to remove the skin of the forgings. For example, a mobile sandblaster with adjustable flow rate, with the application number CN202120542205.8, includes a sandblaster main body. A feeding port is opened on the sandblaster main body, a material cylinder is fixedly arranged inside the sandblaster main body, a feeding port is opened on the material cylinder, a sliding groove is opened inside the material cylinder, a monitoring rod is slidably arranged in the sliding groove, the monitoring rod penetrates through the sandblaster main body, and a conveying pipe is arranged on the sandblaster main body. This utility model can control the rotation speed and rotation of the screw conveyor at the output end of the motor through a frequency conversion controller, control the size of the pipe diameter opening, and cooperate with controlling the rotation speed of the screw conveyor, so as to realize the adjustable flow rate of the sandblaster. Through the cooperation of the two, its practicability is enhanced, and the required flow rate can be adjusted more accurately. A monitoring rod is arranged on this utility model. By observing the scale value on the monitoring rod, the usage amount of the sand is monitored and the flow rate of the sandblaster is adjusted, which is convenient for observing the usage situation of the sand.

[0003] However, when the existing sandblasting equipment sands an object, since the sandblasting materials such as quartz sand and steel shots are sprayed on the material surface, some materials will splash out after contacting the object during the sandblasting process, which is not conducive to the cleaning of personnel and may even cause harm to the operators in serious cases. Therefore, we make improvements and propose a sandblasting and skin-removing device for metal forgings. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a sandblasting and skin-removing device for metal forgings, which can effectively solve the problems that the later cleaning is more troublesome due to the splashing of materials during the sandblasting process and the materials splash on the personnel during the sandblasting process.

[0027] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 to 6 shown, a sandblasting and skin-removing device for metal forgings includes a base 1. A placement rack 5 for storing forgings is arranged on the upper surface of the base 1. A sandblasting assembly 2 for sandblasting is fixedly installed on one side of the base 1. Slide rails 3 are fixedly installed on both sides of the upper surface of the base 1. A shielding assembly 4 for preventing material from splashing out is movably installed on the upper sides of the two slide rails 3. A filter screen 6 for filtering materials is installed under the placement rack 5;

[0029] The sandblasting assembly 2 includes a water storage tank 201 and a material storage tank 202. The upper end of the water storage tank 201 is connected to a transfer branch pipe 207 through a first transfer pump 203. The upper end of the material storage tank 202 is connected to a main transfer pipe 206 through a second transfer pump 204. The transfer branch pipe 207 is connected to the main transfer pipe 206. A spray gun 208 is fixedly installed at the discharge end of the main transfer pipe 206.

[0030] Through the present application, a water storage tank 201 and a material storage tank 202 are respectively provided. The water storage tank 201 stores a cleaning liquid for preventing material from splashing out during spraying, and the material storage tank 202 stores sandblasting materials for skin removal. Under the action of the first transfer pump 203 and the second transfer pump 204, in cooperation with the transfer branch pipe 207 and the main transfer pipe 206, the liquid and the material are mixed together and sprayed out together. As a result, when the material contacts the forging, the material will not splash out in a large area. The splashing area will be reduced under the action of the liquid, avoiding harm to the operator.

[0031] In this embodiment, a water storage tank 7 is provided at the bottom of the base 1. The water storage tank 7 is located below the filter screen 6. A filter element 8 for filtering impurities is fixedly installed on one side of the water storage tank 7. The filter element 8 is connected to the water storage tank 201 through a water pump. A door 9 for enclosing the abrasive blasting material is installed between the placement rack 5 and the filter screen 6 on one side of the base 1.

[0032] Through the placement rack 5, the liquid and the material can be transferred to the lower part to prevent them from remaining on the surface of the forging. Subsequently, the liquid and the material will be filtered under the action of the filter screen 6 to separate the liquid from the material. The liquid will fall into the water storage tank 7, and then the liquid can be circulated back to the water storage tank 201 through the filter element 8, reducing the use of water resources. The material will be retained on the filter screen 6 so that the operator can open the door 9 later to clean it.

[0033] In this embodiment, a wire reel 205 is fixedly installed on one side of the base 1, and a conveying main pipe 206 is wound inside the wire reel 205.

[0034] In this embodiment, the shielding assembly 4 includes a shielding cover 401. A sliding seat 403 is fixedly installed on the lower side of the shielding cover 401. The shielding cover 401 is movably installed above the slide rail 3 through the sliding seat 403. A slot is provided at the opening of the shielding cover 401, and an extended cover plate 402 is installed inside the slot.

[0035] In this embodiment, a motor 409 and a bearing seat 411 are respectively fixedly installed on one side of the upper surface of the base 1. A driving lead screw 410 is fixedly installed at the output end of the motor 409. The rod body of the driving lead screw 410 penetrates through the shielding cover 401 and is in threaded cooperation therewith. The bearing seat 411 is rotatably connected to the driving lead screw 410.

[0036] By starting the motor 409 to drive the driving lead screw 410 to rotate, with the sliding cooperation between the sliding seat 403 and the slide rail 3, the threaded cooperation between the driving lead screw 410 and the shielding cover 401 is utilized, and finally the position of the shielding cover 401 will change. In this application, by adjusting the position of the shielding cover 401, corresponding adjustments can be made according to the size of the forging to be processed, and the extended cover plate 402 can also be pulled out as needed to prevent the splashing of materials.

[0037] In this embodiment, a moving groove 404 is provided on the lower side of the inner wall of the shielding cover 401. A moving seat 405 is slidably installed inside the moving groove 404. A brush plate 406 for cleaning the surface of the placement rack 5 is fixedly installed inside the moving seat 405. A connecting rod 407 is fixedly installed at one end of the moving seat 405, and a handle 408 is fixedly installed at one end of the connecting rod 407.

[0038] To facilitate the cleaning of material impurities by personnel, a brush plate 406 is provided on the lower side of the shielding cover 401. Thus, during the movement of the shielding cover 401, the impurities at the bottom of the shielding cover 401 are uniformly swept into the gaps of the placement rack 5, achieving rapid cleaning. Moreover, the position of the moving seat 405 inside the moving groove 404 can be adjusted by pulling the grip 408, enabling the brush plate 406 to be adjusted accordingly, further improving the cleaning range. Compared with the existing device, this application is more convenient for cleaning impurity materials and reduces the working intensity of personnel.

[0039] The working principle of this metal forging sandblasting and debarking device:

[0040] During use, first adjust the position of the shielding cover 401 according to the size of the material. Start the motor 409 to drive the driving lead screw 410 to rotate. With the sliding fit between the sliding seat 403 and the slide rail 3, the driving lead screw 410 is in threaded fit with the shielding cover 401. Finally, the position of the shielding cover 401 will change. In this application, by adjusting the position of the shielding cover 401, corresponding adjustments can be made according to the size of the forging to be processed.

[0041] After completion, place the forging above the placement rack 5. Then the operator takes out the spray gun 208, aims it at the position where debarking is required. Subsequently, under the action of the first transfer pump 203 and the second transfer pump 204, in cooperation with the transfer branch pipe 207 and the transfer main pipe 206, the liquid and the material are mixed together and sprayed out simultaneously to achieve sandblasting operation.

[0042] During sandblasting, the liquid and the material can be transferred downward through the placement rack 5 to prevent them from remaining on the surface of the forging. Subsequently, the liquid and the material will be filtered under the action of the filter screen 6 to separate the liquid from the material. The liquid will fall into the water storage tank 7 and can then be circulated back to the water storage tank 201 through the filter element 8.

[0043] After sandblasting, the operator takes out the forging. Then start the motor 409 again to adjust the position of the shielding cover 401. By providing a brush plate 406 on the lower side of the shielding cover 401, during the movement of the shielding cover 401, the impurities at the bottom of the shielding cover 401 are uniformly swept into the gaps of the placement rack 5, achieving rapid cleaning.

[0044] Obviously, the above embodiments of the present utility are merely examples for clearly illustrating the present utility, rather than limitations on the implementation manners of the present utility. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present utility still fall within the protection scope of the present utility.
