Description

TECHNICAL FIELD

[0001] The utility model relates to the field of roll processing, especially to a submerged arc welding processing device with recyclable flux. BACKGROUND

[0002] Roll is a key component in steel manufacturing and processing, and its surface often appears wear or damage due to high strength use. In order to prolong the service life of the roll, submerged arc welding technology is usually used for surface processing. However, there are problems of flux waste and welding quality affected in the existing submerged arc welding process, especially the flux falls too fast during welding, which causes the flux to be unable to fully cover the weld, thereby affecting the welding effect. The loss of flux during welding not only wastes materials, but also needs additional labor cleaning cost. In the prior art, although the collection and recycling of flux have been studied, there are still problems of low flux recycling efficiency, mixing of waste materials such as welding slag in the recycling process, etc., which cannot realize efficient flux separation and recycling, resulting in low welding quality and efficiency. The separation of mixed flux and welding slag is difficult, which further increases the production cost.

[0003] Publication No. CN 106076799 B discloses a submerged arc welding flux secondary recycling slag agent separation tool, which comprises a box body, a hopper is arranged at the upper part of the box body, and a receiving box is arranged at the lower part of the box body; the receiving box comprises a flux tank and a welding slag tank, and the flux tank and the welding slag tank are separated by a partition plate; a discharge port is arranged at the bottom of the hopper, and the discharge port is located above the flux tank; a screening plate is obliquely arranged between the discharge port and the flux tank, and the sliding direction of the screening plate is arranged towards the welding slag tank; one end of the screening plate is located directly below the discharge port. The device has the advantages of simple structure, saving of labor cost, and high purity of flux separation, but in the actual welding process, the device cannot meet the rapid recycling of flux, and therefore a device capable of rapidly separating welding slag and recycling is needed. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a submerged arc welding processing device with recyclable flux.

[0005] The utility model has the advantages of separating flux and welding slag by using the vibration mechanism at the bottom of the waste cavity and the separation net plate during submerged arc welding processing of the roll, conveying the separated flux to the welding machine by the conveying pipeline, realizing timely and efficient recycling of flux during production, improving the processing efficiency, and reducing the labor cost.

[0006] In order to achieve the above-mentioned purpose of the utility model, the technical solution of the utility model is: a submerged arc welding processing device with recyclable flux, including a welding machine and a base, characterized in that the base is provided with two clamp seats arranged opposite to each other, a waste chamber is provided between the two clamp seats, a partition mesh plate is provided in the waste chamber to divide the waste chamber into an upper and lower layer, the waste chamber is located on a vibration mechanism, a flux discharge port is provided at the bottom of the waste chamber, a conveying pipe is connected to the flux discharge port, and the welding machine is connected to the flux discharge port through the conveying pipe. The welding slag and the flux are preliminarily separated by the partition mesh plate, and the waste chamber is vibrated by the vibration mechanism so that the flux can be better separated and enter the mesh of the partition mesh plate; the flux and the waste bin are connected by the conveying pipe so that the separated flux can be used for production in a timely manner.

[0007] Furthermore, the base is equipped with a stopper for flaking off the welding slag. A movable assembly is also provided on the base, parallel to the line connecting the two fixture seats, and the stopper is connected to the movable assembly. The addition of the stopper allows welding slag to fall off promptly during processing, preventing it from adsorbing on the workpiece surface and affecting processing. The combination of the movable assembly and the stopper improves the efficiency and range of welding slag flaking.

[0008] Furthermore, the moving assembly is a screw mechanism, which includes a screw and a slider screw-connected to the screw, and the stopper is connected to the slider. The design of the screw mechanism and the slider facilitates the adjustment of the working range of the stopper.

[0009] Furthermore, an elastic member is provided between the stopper and the slider, which can effectively absorb vibrations generated by the operation of the device; the design of the elastic member can improve the applicability of the device when processing welding slag of different shapes.

[0010] Furthermore, the mesh holes on the separation mesh plate gradually become smaller from top to bottom. The mesh holes gradually become smaller from top to bottom to prevent welding slag from falling during separation.

[0011] Furthermore, a circle of R angle is provided at the opening of the mesh hole. The R angle at the opening of the mesh hole can reduce the resistance of the flux when passing through the mesh hole.

[0012] Furthermore, the base is equipped with a bracket parallel to the line connecting the two clamp seats, and the bracket is equipped with a movable rod, which is equipped with a circular arc-shaped mounting slot. The circular arc-shaped mounting slot is equipped with several slightly upward-angled air blowing components. By installing slightly upward-angled air blowing components in the circular arc-shaped mounting slot, a certain intensity of airflow is applied to the workpiece surface, slowing the drop rate of the flux, ensuring that the flux can more evenly cover the welding area, and improving the stability and consistency of the welding effect.

[0013] Further, the gas of the blowing assembly is hot gas. Using hot gas as the output source of the blowing assembly can reduce the influence on the welding area and prevent the temperature from suddenly dropping during the welding process, thereby preventing the welding quality from being reduced.

[0014] Further, the waste cavity side wall is provided with a cleaning door, and the inner wall of the upper cavity separated by the separation net plate is provided with a magnetic assembly. The cleaning door of the waste cavity side wall facilitates the maintenance and cleaning of the device by the operator, the metal impurities in the welding slag mixture are effectively removed by the magnetic assembly, the pollution of the recovered flux is reduced, and the recovery quality of the flux is improved.

[0015] Further, an air blower is arranged on the conveying pipeline. The air blower can optimize the recycling and reuse process of the flux, so that the recovered flux can be quickly put into use, and the production efficiency is improved.

[0016] The utility model discloses the beneficial effect is:
