Flanging die structure of machine cover of crane

Abstract

The invention provides a flanging die structure of a machine cover of a crane, which enables a pressure-shaped flange of the machine cover of the crane to form once without sectional performing, eliminates the artificial beating process step and enables the forming quality of the flange to be high. The flanging die structure comprises a material pressing device, a female die and a male die, and is characterized by further comprising a flanging structure, wherein the flanging structure comprises oblique wedge drivers and oblique wedge sliding plates, wherein the oblique wedge drivers are respectively arranged on the left side and the right side of the female die, the oblique wedge sliding plates are respectively arranged on the left side and the right side of the male die, the oblique wedge sliding plates are mounted on wear-resistant plates, sliding ports are arranged on the wear-resistant plates, sunk grooves are arranged on a male die base corresponding to the lower parts of the sliding ports, a spring is fixedly arranged in each sunk groove, through holes are formed in the oblique wedge sliding plates, elastic pins are plug-in mounted in the through holes, the elastic pins penetrate through the oblique wedge sliding plates and extend into the sunk grooves, one end of each spring is fixed on the side wall in the sunk groove, the other end of each spring is connected with the elastic pin, reverse side blocks are arranged on the outer sides of the oblique wedge sliding plates and on the male die base, each reverse side block body comprises a baffle plate and a baseplate, and cavities are formed between the baffle plates of the reverse side blocks and the oblique wedge sliding plates.

Description

technical field [0001] The invention relates to a die structure for pressing parts of a crane, in particular to a structure of a flanging die for a crane hood. Background technique [0002] The shape of the crane hood is complex and irregular, and the parts are long and deep. Usually, the crane hood flanging process adopts a segmented flanging process, and the complicated parts are knocked manually, which consumes a lot of manpower and material resources and has low efficiency. ,low quality. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a crane hood flanging die structure, which can form the crimping and flanging of the crane hood at one time without segmenting and manual knocking process, and the flanging forming high quality. [0004] Its technical scheme is as follows: it includes a presser, a die, and a punch, and is characterized in that it also includes a flanging structure, and the flanging str...
