Embodiment Construction

[0014] The accompanying drawing shows a schematic structural diagram of an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings and the embodiment.

[0015] As can be seen from the accompanying drawings, the present invention is a streamlined locomotive cab skin, which adopts the block production method of the streamlined locomotive cab skin. One-to-one correspondence of the combined steel mold model, and through the grid holes of the combined steel mold to observe the bonding between the skin and the steel mold from the back of the steel mold to judge the forming degree of the skin; the combined steel mold is a grid plate The visible structure of the beam and the convex surface of the diaphragm of the composite steel mold grid are cut and formed by the laser cutting machine according to the electronic data of the curved surface of the inner surface of the skin. The visual structure of the ...

Abstract

The invention relates to a three-dimension curvature covering molding method of streamline cabin, and relative mould, wherein it separates the cabin; and it is characterized in that: the molding of each block is molded by the combined steel mould relative to the three-dimension curvature cover; when molding, it uses the mesh hole of combined steel mould to watch the adhesive condition of cover and steel mould; the combined steel mould is mesh sheet beam visible structure; the baffle plate cam surface of mesh grid is formed by cutting the curvature of inner surface of cover via laser cutter with electric data; and it comprises longitudinal sheet beam and transverse sheet beam made from steel plates; and the baffle plate convex surface of mesh grid is matched with the curvature of inner surface of cover.

Description

technical field [0001] The invention belongs to a method for manufacturing parts of a locomotive, in particular to a method for forming a three-dimensional curved surface skin of a locomotive driver's cab; the invention also relates to a mold structure of the method, which is mainly used for forming a three-dimensional curved surface skin of a streamlined locomotive driver's cab. Background technique [0002] The locomotive cab is the main part of the locomotive head. With the increase of the locomotive speed, the requirements for the locomotive cab are getting higher and higher. In order to reduce wind resistance, high-speed locomotive cabs are generally made into streamlined locomotive cabs. The existing streamlined locomotive driver's cab skin is mainly made of thin steel plates through the three-dimensional curved surface skin block production method, and then tailor-welded on the driver's cab steel skeleton piece by piece. When the skin is made in blocks, the method of...
