Embodiment 1

[0038] figure 1 A schematic diagram of the appearance and structure of the compartment door 100 in the manufacturing method of the compartment door 100 provided in this embodiment. Please refer to figure 1 , the present embodiment provides a method for manufacturing the compartment door 100 , which uses rolling to make the sheet material into a door panel base material with a predetermined shape. The door panel base material includes a door panel body 110 and two reinforcing parts 120 fixedly connected to opposite ends of the door panel body 110. The free ends of the reinforcement parts 120 have flanges 130, and the flanges 130 are welded and fixed on the door panel body 110 by spot welding. .

[0039] The manufacturing method of the compartment door 100 provided in this embodiment is further described below:

[0040] The welding method provided in this embodiment comprises the following steps:

[0041] SO1: Roll the board to obtain the base material of the door panel; the...

Embodiment 2

[0053] This embodiment also provides a method for manufacturing the compartment door 100. The method for manufacturing the compartment door 100 provided by this embodiment will be specifically described below. The method includes the following steps.

[0054] SO1: Roll the board to obtain the base material of the door panel; the base material of the door panel includes a door panel body 110 and two reinforcing parts 120 integrally formed at opposite ends of the door panel body 110; the free ends of the two reinforcing parts 120 are provided with flanging 130.

[0055] The board is put into the rolling device, and the board is rolled into a door panel base material with a preset shape by the joint action of multiple sets of rollers. The door panel base material includes a door panel body 110 and two reinforcing parts 120 integrally formed at opposite ends of the door panel body 110 , and a flange 130 is provided at a free end of the reinforcing part 120 . Specifically, the rei...

Abstract

The invention relates to the technical field of mechanical manufacturing, and provides a carriage door and a manufacturing method thereof. The carriage door and the manufacturing method thereof aim tosolve the problems of poor commodity of appearance and high production cost of a carriage door in the prior art. The manufacturing method of the carriage door comprises the steps that a plate material is rolled into a door plate base material; the door panel base material comprises a door panel body and reinforcing parts integrally formed at opposite two ends of the door panel body, flanging is arranged at the free ends of the two reinforcing parts, and the flanging are fixed on the door panel body in a welded mode by spot welding. The flanging are welded to the door panel body by spot welding, welding spot exposure is avoided as much as possible, and the commodity of appearance is improved. The flanging and the door panel body are formed by rolling, the degree of attaching between the flanging and the door panel body is high, the gap between the flanging and the door panel body is small after welding, and no gluing operation is required after welding, the commodity of appearance is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a compartment door and a manufacturing method thereof. Background technique [0002] Three-wheeled trucks have been widely used, especially for cargo transportation, due to their light and handy appearance and easy driving. [0003] The three-wheeled truck has a compartment for loading, and the compartment usually consists of a compartment floor and side door panels connected around the floor. The door panel is the main component of the side door panel. Most of the existing door panels have shortcomings such as excessive gaps and exposed solder joints. Moreover, due to the large gaps in the door panels, glueing must be done before the cabin is painted, which not only results in unsatisfactory appearance , and it will also increase the production cost of the door panel, and it is also prone to the problem of abnormal noise during use.
