Description

Batch roller blackening tool Technical Field The utility model relates to the technical field of roller blackening, in particular to a batch roller blackening tool. Background The black oxidation treatment, abbreviated as blackening treatment, is a common surface chemical treatment mode. The blackening treatment can improve the wear resistance and rust resistance of the steel material. Bearing products in industries with higher requirements such as wind power, shield and the like often require blackening treatment of a ferrule and a rolling body, and the surface quality of the bearing is improved. The blackening treatment is carried out by adopting a soaking method, placing the steel product into a prepared high Wen Heihua liquid, and generating a layer of blackening film on the surface of the steel product after a certain time of chemical reaction, thereby completing the blackening process, wherein the blackening requirement of the roller is that the surface blackening layer is uniform, and no fault is allowed. In the prior art, the blackening method is generally to prop up one end of the roller by adopting angle steel, and put a batch of rollers into a blackening tank in an inclined manner so that blackening liquid is fully contacted with the rollers. The blackening method has the defects that the contact part of the roller raceway surface with the angle steel is not fully contacted with blackening liquid, so that blackening fault is generated in the area, the roller raceway surface is a stress area, uneven stress of the raceway is easy to be caused, and the damage is large. In addition, the circulating flow direction of the blackening liquid in the blackening tank is from bottom to top, and the flow of the blackening liquid at the angle steel is poor in a manner of inclining the roller by the angle steel, especially near a fulcrum, and the blackening effect at the position can be influenced to a certain extent, so that the appearance of the roller is marked. In summary, it is necessary to design a better roller blackening tool, and the ideal blackening effect is achieved by fully and uniformly contacting with the blackening liquid. Disclosure of utility model In order to solve the technical problems, the utility model provides a novel batch roller blackening tool. The technical scheme includes that the batch roller blackening tool comprises a plurality of connecting thin plates and a plurality of supporting thin plates, wherein a plurality of grooves which are arranged at intervals are formed in each connecting thin plate, the positions of the grooves formed in the connecting thin plates correspond to each other, at least one V-shaped groove is formed in each supporting thin plate, and the supporting thin plates are arranged in parallel and clamped in the grooves of the connecting thin plates through the bottom edges of the supporting thin plates to form a multi-row supporting structure for supporting rollers. Preferably, the width of the grooves is the same as the thickness of the support sheet, and the distance between each groove is equal. Preferably, the support thin plate is provided with a plurality of V-shaped grooves, and the positions of the V-shaped grooves on the adjacent support thin plates correspond to each other. Preferably, the distance between the rollers of the two rows is greater than half the diameter of the rollers. Preferably, the rollers are horizontally placed on the support sheet, and the chamfer of the rollers is in contact with the support sheet. Preferably, the support sheet and the connecting sheet are made of sheets with the thickness of 3mm-6mm, and are assembled in a clamping groove connection mode. The beneficial effects of the utility model are as follows: Based on the defects existing in the prior art, the utility model provides a batch roller blackening tool, which has the following technical effects by optimizing structural design: Firstly, the V-shaped grooves are formed in the support thin plate, and the rollers are horizontally placed in the support structure formed by the adjacent V-shaped grooves, so that the rollers are contacted with the support thin plate only through the chamfer areas, and the direct contact between the raceway surface and the tool is avoided. The design solves the problem of blacking fault of the raceway surface caused by the traditional angle steel supporting mode, and ensures enough intervals among rollers by controlling the distance and the angle of the V-shaped grooves, so that blacking liquid can uniformly flow and fully contact with the surfaces of the rollers, thereby improving the uniformity and the comprehensiveness of the blacking effect. Secondly, the grooves on the connecting thin plates are afraid of and matched with the supporting thin plates, and the multiple rows of supporting thin plates are fixed on the connecting thin plates in a clamping groove connection mode, so that a stable supporting structure is formed.
