Embodiment Construction

[0023] A mining dump truck frame assembly production process, the specific process steps are as follows:

[0024] 1) Make the left and right longitudinal beams: a. Cut the steel plate into strips; b. Drill the hole positions of the longitudinal beams with template sleeves; c. Cut the shape with CNC plasma; d. Bending, the upper airfoil is bent twice; e, a long section of the airfoil is bent down at the variable section and then welded;

[0025] 2) Make small parts of the beam: a. Cutting the small parts of the rear beam; b. The steel pipe beam of the second beam is formed by a mold, and a set of welding tooling is made to weld the second beam assembly; c. Riveting or welding of the tooling become;

[0026] 3) Frame assembly tailor welding: a. Make frame assembly tailor welding tooling; b. Longitudinal beam tailor welding.

[0027] The tailor welding of longitudinal beams includes the following steps:

[0028] 1) Spot-weld the inner reinforcement plates of the left and right...

Abstract

The invention relates to a self-discharging vehicle frame assembly production technology for mine, which comprises following specific technology steps: a). manufacturing left and right longitudinal beams; b). manufacturing horizontal beam small members; c). welding the frame assembly through putting together. According to the invention, the method has convenient processing; the height of center of gravity of the whole vehicle is lowered; the weight of the whole vehicle is reduced; the bending rigidity of the whole frame is improved; and the torsion rigidity of the whole frame is enhanced.

Description

technical field [0001] The invention relates to a mine dump truck frame, in particular to a production process for a mine dump truck frame assembly. Background technique [0002] Existing mining vehicles are frame-plus-sub-frame structures, which have a high center of gravity and increased vehicle weight. In order to reduce the weight and improve the bending stiffness and torsional stiffness of the vehicle frame, it is necessary to improve them. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mining dump truck frame assembly production process that is convenient in processing, lowers the height of the center of gravity of the whole vehicle, reduces the weight of the whole vehicle, improves the bending stiffness of the vehicle frame, and improves the torsional stiffness of the vehicle frame. [0004] Technical scheme of the present invention is: concrete processing step is as follows: [0005] 1) Make the left and r...
