Embodiment Construction

[0017] In order to obtain the precision of the hole system after the product is formed, it must be controlled from every link of the sheet metal opening and leveling, CNC shearing and blanking process. If the internal stress of the material itself is not completely released by the flattening of the sheet metal, it will cause the phenomenon of camber bending in the strip material in the shearing and blanking process, resulting in the drift of the CNC punching hole system, resulting in a height difference between the upper and lower airfoils after bending and forming, serious cause the product to be scrapped. Therefore, the monitoring of pressure parameters in each link (pre-leveling and fine leveling) is strictly controlled during sheet metal opening. The straightness of the first and last piece of sheet metal is tested and controlled, and the cutting parameters are adjusted in time to ensure that each process link is in a controlled state, so that the sheet material is in the ...

Abstract

The invention discloses a process method for bending and forming a straight-through vehicle frame inner beam with a hole. The original process mode that only part of a plug welding hole is formed in the inner beam is changed, and is not equal to the vehicle frame loading efficiency through the process method that an inner beam hole is drilled in a sleeving manner after the inner beam and the outerbeam are embedded. By improving the process of realizing all hole sites of the inner beam and bending, the purposes of improving the precision of a hole system after the inner beam is formed and thealignment precision of the hole system after the inner beam and the outer beam are embedded, reducing the working strength of the inner beam of the sleeve drill and improving the working efficiency are achieved.

Description

technical field [0001] The invention relates to a method for bending and forming an inner beam of a vehicle frame, in particular to a process method for bending and forming a through-hole inner beam of a vehicle frame. Background technique [0002] In order to improve the loading efficiency of the frame assembly is currently the primary task of small and medium-sized auto parts and frame assembly processing enterprises, strengthening the process quality control of parts and process improvement plays a decisive role in the loading efficiency. However, the single-shift production efficiency of the original direct drilling process of the inner and outer beam sleeves of the frame is lower than the assembly efficiency of the frame assembly, so that the sleeve drilling process is relatively lagging behind, and the advance of production organization is uncontrollable. In order to improve the working efficiency of hole-through inner beams, it is imperative to improve the bending for...
