Description

Technical Field

[0001] The utility model relates to a shaping device, in particular to a shaping device for the tail of a longitudinal beam of an automobile frame. Background Art

[0002] Under the existing technology, the longitudinal beams of automobile chassis frames are generally made of C-shaped steel. In order to facilitate the installation of other components, the ends of the longitudinal beams need to be shaped, that is, the ends of the C-shaped steel are processed into an inclined shape through cutting and re-welding processes. In the current process, the side panels of the cut C-shaped steel need to be bent at the tail and then welded to the bottom panel. In this part of the process, the tail shaping process is generally performed manually, which is not only laborious and time-consuming, but also during welding, due to the high toughness of the C-shaped steel, there is a problem that the side panels and the bottom panel cannot maintain a close contact state, resulting in the welding process cannot be completed in one go. Summary of the Invention

[0003] In order to solve the problems of the prior art, the utility model provides a tail shaping device for a longitudinal beam of an automobile frame, which can not only quickly complete the tail bending and shaping process of the C-shaped steel to be processed, but also ensure that the side wall of the C-shaped steel and the trimmed bottom plate are tightly fitted before welding, thereby facilitating welding.

A clamping mechanism is slidably provided on the L-shaped baffle, and the clamping mechanism is used to clamp and position the longitudinal beam workpiece to be shaped after the tail shaping mechanism shapes the tail end.

[0011] The beneficial effects brought about by the technical solution provided by the utility model are:

[0012] The utility model discloses a tail shaping device for a longitudinal beam of an automobile frame. The tail shaping mechanism can quickly shape the tail of a side panel of a cut C-shaped steel so that the side panel is aligned with the inclined surface of a cut bottom panel. At this time, only spot welding is required at the joint to quickly and accurately complete the shaping process of the C-shaped steel end, thus avoiding the inconvenience of using manual labor or simple tools in the prior art.

[0013] The tail shaping mechanism utilizes an articulated structure, allowing the entire tail shaping plate, driven by a hydraulic cylinder, to apply pressure to the entire C-shaped steel sidewall throughout the entire process, rapidly bending it toward the base plate and achieving a perfect fit with the base plate for easy welding. The tail shaping mechanism's rubber-coated rollers, combined with side positioning baffles, ensure the stability of the entire C-shaped steel as it is fed into the longitudinal beam welding station. The vertical pressure of the clamping mechanism ensures the stability of the entire tail shaping process. The hydraulic cylinder's upper cover and connecting beam structure shield the hydraulic cylinder and the longitudinal beam being processed, enhancing work safety. BRIEF DESCRIPTION OF THE DRAWINGS
