Shaping device for cylindrical flange plate after forging and working method

Abstract

The invention relates to the field of flange plate forging, in particular relates to to a shaping device for a cylindrical flange plate after forging and a working method. The shaping device comprisesa base, a supporting frame, a controller, a rotating mechanism, a repairing mechanism and a position adjusting mechanism, wherein the rotating mechanism comprises a machining table and a rotating component; the position adjusting mechanism is arranged at the top of the base so as to support the repairing mechanism to adjust the position, and the position adjusting mechanism comprises a lifting plate, a sliding component and a jacking component; the repairing mechanism comprises a bearing plate, a hammer head, a spray head, a material receiving pipe, a pushing component and a discharging component; and the rotating component, the sliding component, the jacking component, the pushing component and the discharging component are electrically connected with the controller. According to the shaping device for the cylindrical flange plate after forging and the working method, various defects on the outer wall of the flange plate can be detected in time and repaired in time, and meanwhile, most of repairing modes are automatic; and meanwhile, frequent contact of workers is not needed in the repairing process, and thus potential safety hazards are small.

Description

technical field [0001] The invention relates to the field of forging flanges, in particular to a shaping device and working method for forged cylindrical flanges. Background technique [0002] The oil filling device on the top of the tanker includes a support flange, the diameter of the support flange is Ø699mm, the outer diameter of the cylindrical part is Ø540mm, the inner diameter is Ø508mm, and the wall thickness is 16mm. The weight of the supporting flange made of ASTM A350 is 118kg. At present, for the manufacture of such large thin-walled flanges, only the method of forging the membrane can be used. The process steps are as follows: firstly select a blank with a weight of 300kg, then use the inner upsetting of the membrane, then punch small holes, and then pass through The method of multiple reaming is preformed; finally, the finished product is made by cutting. After the flange is preformed, its outer wall is likely to bulge due to the uneven distribution of the ...

AI Technical Summary

Problems solved by technology

[0006] 1. There is no plastic structure design, and after the flange is forged, it is impossible to detect defects such as swelling and cracks on the outer wall of the flange in time

As a result, the quality and subsequent processing of the flange cannot be guaranteed.

[0007] 2. Workers need to touch the mold frequently, and most of them are manually operated. When they are in contact with the mold, they are prone to danger. Therefore, there are certain safety hazards
