Abstract

The invention discloses a special straightening machine for vehicle frame longitudinal beam flanges. The special straightening machine comprises a mobile portal frame, a straightening device, a hydraulic system and an electric control system, wherein the mobile portal frame comprises a portal and a fixed rail; a pulley is arranged at the bottom of the portal and moves along the fixed rail; the straightening device is suspended in the top position of the mobile portal frame, and comprises a straightening clamp and a straightening oil cylinder; the straightening oil cylinder provides power to the straightening clamp for extruding workpieces; the hydraulic system provides oil pressure to the straightening oil cylinder of the straightening device; the electric control system controls the mobile portal frame to move and controls the hydraulic system to provide the oil pressure. The special straightening machine plans to adopt the hydraulic straightening clamp to simulate manual straightening and applies force to workpiece flanges in a segmented manner, so that the parts, deformed due to welding, of the workpieces are plastically changed to achieve the purpose of straightening the workpiece flanges.

Description

technical field [0001] The invention relates to the technical field of rectification of sheet metal weldments, in particular to a special rectification machine for longitudinal beam flanges of vehicle frames. Background technique [0002] At present, the automobile industry is highly developed, and the requirements for machining precision and welding precision of automobile parts are getting higher and higher. The design and manufacture of CNC machine tools and their tooling can ensure the production quality of mechanical parts. At the same time, during the welding production process of workpieces, welding Due to the concentration of heat output at the seam, the workpiece is deformed. For example, a certain frame longitudinal beam product is a double-layer welded special-shaped structure, the material is alloy structural steel, the tensile strength is 600-900MPa, the yield strength is 600-850MPa, and the length of the longitudinal beam is 8m-20m. [0003] Due to the double-...
