A container roof roll forming process and its equipment

Abstract

The invention discloses a roller forming technique for a container top plate. The roller forming technique comprises the step that steel coils are continuously unreeled and blanked. The roller forming technique further comprises the following steps that a, the steel coils are subjected to roller forming; b, the steel coils are subjected to camber forming; c, sizing and cutting are conducted; and d, trimming is conducted. The periphery of rollers used in the step a for roller forming are provided with notches. The outer perimeter of the rollers is equal to the length of the container top plate. The invention further provides roller forming equipment for the container top plate. The roller forming equipment comprises an unreeling device and a conveying device. The roller forming equipment further comprises a roller press, camber forming equipment, a shearing machine and an edge trimmer. According to the top plate forming method, the production efficiency of the container top plate can be greatly improved; after a steel plate is unreeled, required blind waves are firstly pressed on the steel plate through the rollers, then the steel plate is subjected to camber forming, and finally the steel plate is sized and cut off. The assembly line operation production of the container top plate can be continuously conducted.

Description

technical field [0001] The invention relates to a container production process, in particular to a production method and equipment for a container top plate. Background technique [0002] Containers are widely used all over the world as a common means of transportation. At present, the conventional container roof generally adopts the blind wave roof (that is, there is a depression in the middle of the container roof, and the surrounding structure is closed, see the attached figure 1 ), the blind wave on the top plate is integrally formed. Moreover, in addition to blind waves, the roof also requires a certain amount of horizontal camber and vertical camber to facilitate drainage in rainy days. Therefore, in the face of such workpieces, the current processing method is basically to use a punching machine with a mold to press and form (such as the container roof forming process and equipment in Chinese patent application No. 201110284080.4). [0003] However, due to the long...

Problems solved by technology

[0003] However, due to the long molding time period of the press molding, in order to ensure that the workpiece does not rebound during pressing, a longer holding time is required after the press is pressed down. Not only that, because the top plate also needs to have a follow-up after pressing. The processing of the roof plate from the press to other processes often requires other auxiliary devices, so it is difficult to guarantee the continuity of production, and finally makes it difficult to improve the production efficiency of the container roof plate
