Description

Technical Field

[0001] The utility model relates to the technical field of commercial vehicle frame longitudinal beams, in particular to a commercial vehicle frame longitudinal beam tail end forming tool. Background Art

[0002] The tail end of the longitudinal beam of some commercial vehicle models is a variable cross-section. The existing technology cannot directly process the longitudinal beam into a variable cross-section when rolling the longitudinal beam. First, plasma cutting is performed according to the drawing, and a triangular shape is cut off on the variable cross-section side. Then the processing personnel need to repeatedly hammer the two sides after cutting to overlap them, and finally weld the two sides through welding technology, such as Figure 1-3 shown.

[0003] However, this processing method currently has the following shortcomings: after plasma cutting, the forming process relies entirely on manual operation by the processing personnel, which is heavy physical labor. Long-term work is harmful to the health of the processing personnel. At the same time, the processing is time-consuming and inefficient. In addition, there are differences in the technical level and physical condition of the processing personnel, which may result in the process quality failing to meet the requirements of the drawings. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a rear end forming tool for a commercial vehicle frame longitudinal beam.

[0005] The utility model adopts the following technical solution to solve the technical problem: a commercial vehicle frame longitudinal beam tail end forming tool, comprising an upper frame and a lower frame, wherein a first hydraulic cylinder penetrating the upper frame is provided on the top of the upper frame, and a clamping block is installed at the end of the first hydraulic cylinder to fix the longitudinal beam; intermediate modules and symmetrically distributed forming mechanisms are provided on both sides of the lower frame, and the forming mechanism is provided with a second hydraulic cylinder penetrating the side of the lower frame, and a clamping block is installed at the end of the second hydraulic cylinder to squeeze the edge of the longitudinal beam.

[0006] Preferably, symmetrical first guide tubes and first guide columns are provided on both sides of the first hydraulic cylinder, and the first guide columns penetrate the upper frame and are connected to the pressing blocks.

[0007] Preferably, symmetrical second guide tubes and second guide columns are provided on both sides of the second hydraulic cylinder, and the second guide columns penetrate the lower frame and are connected to the pressing blocks.

[0008] Preferably, the upper half of the pressing block is a right-angled trapezoidal structure, and the lower half of the pressing block is a rectangular structure.

[0009] Preferably, the upper part of the middle module is an isosceles trapezoidal structure, and the lower part of the middle module is a rectangular structure.

[0010] The utility model has the following beneficial effects:

[0011] 1) Improve processing efficiency. By replacing the manual forming in the existing technology with forming tooling, the processing time is greatly shortened and the processing efficiency is improved;

[0012] 2) Improve processing quality. In the existing technology, the forming is completely achieved by the hammering of the processing personnel, which is greatly affected by the processing level of the processing personnel. The forming tooling can reduce the influence of subjective factors and ensure the processing quality;

[0013] 3) Reduce unsafe factors during the processing. BRIEF DESCRIPTION OF THE DRAWINGS
