Abstract

The invention provides a novel integrated compartment board and a production process thereof, which relates to the technical field of car panels, and solves the technical problems of easy water inflowcracking and low strength at the welding seam of the compartment board produced by the split production method. The device comprises a flat plate part and a corrugated part, wherein the corrugated part is arranged on either side or both sides of the flat plate part, and the corrugated part and the flat plate part are integrally formed; The invention also discloses a manufacturing process for producing the integrated box plate, wherein the special-shaped wheels of more than 30 groups are used to perform rolling in a small amount for many times; The rectangular folded edge and the integrally formed structure of the invention can ensure that the strength of the whole compartment plate is greatly increased; And the whole box plate has no welding seam, and the whole box plate is not easy to befilled with water, so that the service life of the box plate is enhanced; 30 or more group of rollers are arranged in that production process, and the angle of the rollers is adjusted for many time to press and deform, so that the cold-rolled sheet is not easy to break in production, and the box plate is seamless and integrally formed.

Description

technical field

[0001] The invention relates to the technical field of compartment panels, in particular to a novel integrated compartment panel and a production process. Background technique

[0002] Existing car panels mainly include a flat part and a corrugated part, wherein the setting of the corrugated part is to enhance the strength of the car panel; in the actual production process, the above-mentioned flat part and corrugated part are mainly produced separately The flat part and the corrugated part, and then the flat part and the corrugated part are welded to form a whole box board. In addition, it is necessary to weld the edge on the side of the corrugated part.

[0003] The applicant has found that the prior art has at least the following technical problems: the above-mentioned method of split production or splicing of the compartment panels easily leads to the following problems. Water in the splicing gap, long-term rain erosion, the weld is easy to crack, warp a...
