Abstract

The invention discloses a mechanical removal method of technical allowance of a specially-shaped sheet metal part. A workblank of the specially-shaped sheet metal part is of a Z-shaped structure formed by sequential connection of a first horizontal portion, a first hook-face portion, a tilt portion, a second hook-face portion and a second horizontal portion. The mechanical removal method includes the steps of 1), placing a part blank on bottom tooling; 2), providing one positioning block with one horizontal bottom and four side faces and placing the positioning block on the part blank to have the first side face and the second hook-face portion adhered; 3), providing a pair of stick-shaped pressing plates and arranging the same on the part blank; 4), a machine tool control system controlling a tool to cut two side edges according to distance value between the second side face and theoretical edges of two sides respectively and controlling the tool to cut the front and rear edges according to distance value between the third side face and the front theoretical edge and the rear theoretical edge respectively to obtain the specially-shaped sheet metal part of theoretical size. The mechanical removal method is simple, convenience in clamping is achieved, and stability in machining quality is realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing of sheet metal parts, and in particular relates to a method for mechanically cutting off the process margin of special-shaped sheet metal parts. Background technique [0002] Special-shaped aluminum alloy sheet metal parts are widely used in aerospace and rail transit and other fields. Such parts have high requirements on appearance, and require docking with other regular sheet metal parts during assembly, and require high surface quality. In the case of a special aluminum alloy laser cutting machine, it is faster and more efficient to trim the edge by machining processing methods. [0003] At present, the more common method of removing the process margin of sheet metal parts is to use special processing (including laser cutting, wire cutting, water cutting), but laser cutting and water cutting machine tools are expensive, and the processing cost is relatively high. less efficient....
