Abstract
The invention relates to a drawing processing method of a permanent seat. The drawing processing method comprises the following steps: (1) processing preset holes; (2) performing drawing molding; (3) removing residual edges and burrs; (4) hobbing a circular arc opening; (5) punching a fixing hole and a locating hole; (6) punching an assembling hole; (7) removing a sharp angle and burrs; and (8) spraying plastics and coating. An assembling preset hole, a fixing preset hole and a locating preset hole are punched on an iron sheet, the assembling preset hole has a locating function to the iron sheet in a drawing die, the fixing preset hole and the locating preset hole have a function of a patching space to the iron sheet when the vertical plane of the single side is drawn, during drawing, since the ratio of the material thickness to the diameter and the height of a part exceeds the ultimate elongation of the material, deformation fracture occurs, the vertical plane can be prevented from deformation and fracture due to a patching space, so that the extension rate of the material is improved, after drawing, although the fixing preset hole and the locating preset hole are deformed, the fixing hole and the locating hole, having the required sizes, can be re-punched by follow-up punching.
Description
Technical field
The present invention relates to the stretch process method of fixing seat.Such as the production of the fixing seat of automobile hanging.
Background technology
In the assembling of some parts, (such as automobile hanging) needs to use fixing seat, this fixing seat generally cylindrical shape, the upper oral part of fixing seat is shaped with in fixing seat and stretches, and it is shaped with vertical plane at its sidewall, prior art manufactures this fixing seat, generally adopt stretching die that iron plate is drawn into cylinder, with punch press, another iron plate is struck out vertical plane again, finally vertical plane is connected molding with cylinder by electric welding, electric welding processing cost is high, fastness is poor, perpendicularity does not reach requirement, and electric welding junction is unsightly, cylinder and vertical plane are processed at twice, processing cost is high, process-cycle is long, production efficiency is low.
Summary of the invention
The invention aims to the shortcoming overcoming prior art to exist, it is provided that a kind of cylinder and vertical plane one drawing and forming, fastness is good, and intensity is high, good looking appearance, and the process-cycle is short, and production efficiency is high, it is adaptable to the drawing process of the fixing seat of automated production.
The technical scheme of the drawing process of the fixing seat of the present invention is: it is characterized in that: include following procedure of processing:
