Embodiment 1

[0015] A process for assembling and welding a dump truck with reserved stress-inflated anti-expansion compartment mainly includes the following steps:

[0016] (1) Determine the position where the side panel of the carriage receives the maximum lateral force. After the finite element analysis, it is clear that the front 1 / 4 of the side panel of the carriage (viewed from the front to the rear) is the easiest position to expand the compartment.

[0017] (2) Reserve the deformation stress of the side plate assembly, reverse the deformation of the side plate assembly at the maximum lateral force through the special pad and pressure mechanism, and then weld the side plate so that after the side plate is welded, the front end 1 / The 4 places have the largest lateral stress.

[0018] Place a special pad on the left and right sides of the 1 / 4 position of the side plate of the carriage, use the gantry compression frame to apply pressure on the 1 / 4 of the side plate of the carriage, and...

Abstract

The invention discloses a dumper stress reserving carriage expansion prevention assembling and welding technology. The technology comprises the following steps that firstly, the positions where carriage side plates are subjected to the largest lateral force are determined, and it is determined that the 1 / 4 position of the front ends of the carriage side plates are the positions where carriage expansion is most likely to happen through the finite element analysis; secondly, the side plate assembly deformation stress is reserved, reversible deformation is carried out on the positions where carriage side plate assemblies are subjected to the largest lateral force through special cushion blocks and pressure mechanisms, the side plates are welded, and the lateral stress of the 1 / 4 positions of the front ends of the side plates is largest after welding; thirdly, a pressing mechanism is used for carrying out carriage assembling and welding, pressing power units exert pressure on the assembling and welding positions through walking mechanisms, the side plates are straightened, and after the side plates are closely attached to bottom plates, the side plates and a bottom plate assembly are welded. The stress can be reserved at the 1 / 4 positions of the side plates of a carriage, and the carriage expansion situation in the carriage using process is avoided. The technology is suitable for producing dumper carriages of various types within 10 m; operation is easy, a special tool is used for dismounting, and maintaining is convenient.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a process for assembling and welding a dump truck with reserved stress-prevented expansion compartments. Background technique [0002] At present, during the use of the dump truck, the compartment is prone to swelling, which not only reduces the load-bearing performance of the compartment, but also affects the transportation safety of the compartment. Contents of the invention [0003] The invention provides a process for assembly and welding of a stress-reserved anti-expansion compartment of a dump truck. The compartment prepared by this process can prevent the compartment expansion problem during use. [0004] A process for assembling and welding a dump truck with reserved stress-inflated anti-expansion compartment mainly includes the following steps: [0005] (1) Determine the position where the side panel of the carriage receives the maximum lateral force. After th...
