Abstract

The invention provides a pressing part structure for a bent plate of a crane, which can prevent a lower die from separating and reciprocating due to unbalanced stress in a pressing process, thereby ensuring the bearing strength of the die and prolonging the service life of the die. The structure comprises a lower die body and a lower die holder welding part structure, wherein the lower die holder welding part structure comprises a base plate, a base upper plate and a base. The structure is characterized in that: the lower die body is a whole embedded lump; the base plate and the base are mounted and fixed by virtue of bolts and pins; and the base and the base upper plate are connected by virtue of welding.

Description

technical field [0001] The invention relates to a mold device for deformation of a crane tailstock part, in particular to a structure of a bent plate pressing part of a crane. Background technique [0002] Crane tailstock parts are usually bent plate parts, and the manufacture of bent plate parts requires pressing a plate of a certain shape through a deformation die device. At present, the mold equipment used in China for the deformation of crane tailstock parts has a structure: the workpiece is asymmetrical, the spliced ​​lower mold is split, and the welded parts of the lower mold seat are designed using the conventional design method of welding and assembly sequence from bottom to top, that is, the base plate 1. The base is welded and then connected with the upper plate of the base by screws. This structure has the disadvantages that the unbalanced force is easy to cause the split of the lower mold, and the bearing strength of the mold is weak, which affects the service li...
