Problems solved by technology

[0002] The center frame is the main accessory on the agricultural tiller. Generally, the center frame is installed in the middle of the tiller to play the role of connection and fixation. Therefore, the technical requirements are relatively high. At present, the center frame is formed by hand, that is, the workpiece is placed in the vise Clamping on the upper part, then heating the product, and finally beating it with a hammer to form it. This processing method is inefficient, labor-intensive, and the processing size is easy to be out of tolerance. The processed product cannot meet customer requirements, and the production cost is too high. high

Abstract

An upper die for integral forming of a center frame comprises a shank, an upper die base, an upper die block, an upper moving forming die, a bolt and a positioning pin. The shank is arranged at the topmost of the upper die base and connected with the upper die base in a tight fit manner. The upper die block is arranged right under the upper die base and connected with the upper die base through the bolt and the positioning pin. The upper moving forming die is arranged under the upper die block. A bottom slant of the upper die block matches with a top dovetailed groove of the upper moving forming die and is fixedly connected to the same through the bolt. The upper die has the advantages that production efficiency can be improved, costs are lowered, the technical requirement on product quality is effectively guaranteed, good size uniformity is ensured, and the outer surface of each product is attractive.

Description

technical field [0001] The invention relates to a stamping die accessory, in particular to an upper mold for integrally forming a center frame. Background technique [0002] The center frame is the main accessory on the agricultural tiller. Generally, the center frame is installed in the middle of the tiller to play the role of connection and fixation. Therefore, the technical requirements are relatively high. At present, the center frame is formed by hand, that is, the workpiece is placed in the vise Clamping on the upper part, then heating the product, and finally beating it with a hammer to form it. This processing method is inefficient, labor-intensive, and the processing size is easy to be out of tolerance. The processed product cannot meet customer requirements, and the production cost is too high. high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an upper die fo...
