A sheet metal stamping mechanism and stamping method of a hollow disc dryer

Abstract

A sheet metal stamping mechanism and stamping method of a hollow disc dryer, belonging to the field of stamping technology, comprising an upper mold base and a lower mold base, the upper mold base includes an upper template and a die, and the die is set on the upper The bottom end of the template, the inside of the concave mold is equipped with a lubrication assembly, the inside of the lower mold base is equipped with a punch, the punch includes a base and an ejector block, and the bottom of the base is fixed to the lower mold base connection, the center of the top outer surface of the base is fixedly connected with an adjustment rod, the ejection block is slidingly connected with the base through the adjustment rod, the ejection block is provided with an adjustment hole assembly, and the ejector is set in the punch of the lower die base. The block can facilitate the removal of the hollow disc left in the limit groove after stamping, and the punch is composed of a ejector block and a base, which can facilitate the lubricating component to add lubricating oil to the punch and improve the uniformity of lubricating oil addition Sex, thereby reducing the degree of stickiness of waste materials, thereby improving the stamping efficiency of the stamping mechanism.

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
