Oil tank body shaping machine

Abstract

The invention discloses an oil tank body shaping machine, which comprises a frame, a lower shaping frame horizontally arranged on one side of the frame, at least one oil cylinder which is vertically arranged on the lower shaping frame and of which the piston rod extends upwards, and an upper shaping frame horizontally arranged at the upper end of the piston rod. The upper shaping frame and the lower shaping frame are symmetrically arranged; and an arc-shaped chamfer is formed on each side of the upper shaping frame and the lower shaping frame in the width direction. Two oil cylinders are symmetrically arranged; the upper shaping frame is arranged at the upper ends of two piston rods through two hinge bases; the upper end of each hinge base is fixedly connected with the upper shaping frameand the lower end of each hinge base is hinged with the upper end of a corresponding piston rod through a pin shaft; two groups of mutually symmetrical guide pieces are arranged between the lower shaping frame and the upper shaping frame; each group of guide pieces consist of a lower guide post and an upper conduit which are sleeved internally and externally and are vertically arranged; the lowerend of the lower guide post is fixedly connected with the lower shaping frame; and the upper end of the upper conduit is fixedly connected with the upper shaping frame. The oil tank body shaping machine can conveniently shape the arc-shaped chamfer of an oil tank body, and has better shaping effect and higher efficiency.

Description

technical field [0001] The invention relates to a fuel tank shaping machine matched with the motor vehicle fuel tank. Background technique [0002] As one of the auto parts, the fuel tank has many types and models. The main shape of the fuel tank is mostly a square box, and there are four arc-shaped chamfers in the width direction of the box. In the process of making the fuel tank, firstly, the plate body is rolled into a square shape with a rolling machine, and the seam welding machine is used for straight seam welding, and then the obtained tank body is assembled with an end cover and a partition. [0003] During the production process of the box body, the arc-shaped chamfers are often locally deformed. If the shaping is carried out by manual and partial knocking with the help of a wrench, the shaping effect is poor, and it is time-consuming, labor-intensive, and inefficient, so it is not suitable for mechanization Mass production.
