Metal plate stamping mechanism of hollow disc dryer and stamping method of metal plate stamping mechanism

Abstract

The invention relates to a metal sheet stamping mechanism of a hollow disc dryer and a stamping method of the metal sheet stamping mechanism, and belongs to the technical field of stamping. The metal sheet stamping mechanism comprises an upper die base and a lower die base, the upper die base comprises an upper die plate and a female die, the female die is arranged at the bottom end of the upper die plate, a lubricating assembly is installed in the female die, and a male die is installed in the lower die base. The male die comprises a base and an ejection block, the bottom end of the base is fixedly connected with the lower die base, an adjusting rod is fixedly connected to the center of the outer surface of the top end of the base, the ejection block is connected with the base through the adjusting rod in a sliding mode, an adjusting hole assembly is formed in the ejection block, and the ejection block is arranged in the male die of the lower die base. A hollow disc remaining in a limiting groove after stamping can be conveniently taken out, the male die is composed of the ejection block and the base, lubricating oil can be conveniently added to the male die through the lubricating assembly, the lubricating oil adding uniformity is improved, the sticking degree of waste is reduced, and then the stamping efficiency of the stamping mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a sheet metal stamping mechanism of a hollow disc dryer and a stamping method thereof. Background technique [0002] Stamping is a forming process that relies on presses and molds to apply external forces to plates, strips, pipes, and profiles to cause plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Stamping can produce materials that are difficult to obtain by other methods. Manufactured workpieces with ribs, ribs, undulations or flanges to increase their rigidity. [0003] The prior art, wherein the publication number is CN110560567B, discloses a stamping die and stamping method for the left door of the crane, including a bottom plate and a top plate, the bottom plate is arranged below the top plate, and the outer surface of the upper end of the bottom plate is A lower formwork is provided, and main positioning columns are fixed...

[0003] The prior art, wherein the publication number is CN110560567B, discloses a stamping die and stamping method for the left door of the crane, including a bottom plate and a top plate, the bottom plate is arranged below the top plate, and the outer surface of the upper end of the bottom plate is A lower formwork is provided, and main positioning columns are fixedly installed on the outer surface of the upper end of the lower formwork near the corners, and auxiliary positioning columns are fixedly installed on the outer surface of the upper end of the lower formwork near the front end and the rear end. The upper outer surface of the lower template is provided with a lower mold body; the lower outer surface of the top plate is provided with an upper template, and the corner position of the lower outer surface of the upper template is fixedly welded with a mounting seat, and the lower outer surface of the upper template Auxiliary positioning sleeves are fixedly installed near the front end and near the rear end, and the upper mold body is provided on the outer surface of the lower end of the upper mold plate. The above invention can better push out the formed raw materials and protect the The mold avoids the damage of the mold and prolongs the service life of the mold. However, because the upper template and the lower template are in the process of stamping, the upper template produces a huge impact on the lower template, which leads to the phenomenon of sticking between the stamping workpiece and the lower mold. Only through the top plate to eject the workpiece, there is still a sticking phenomenon between the punched workpiece and the top plate on the lower mold, which makes it difficult to remove the mold. When stamping the sheet metal of the hollow disc dryer, the top After the ejection mechanism has been used for a long time, it is difficult to achieve the lubrication of the ejection mechanism, which leads to the problem of low stamping efficiency of the stamping mechanism, which is not convenient for the stamping mechanism to stamp the sheet metal
