Abstract

The invention relates to semitrailer integral axle tube extrusion moulding equipment, comprising a hydraulic machine and an intermediate frequency heating furnace, wherein the two ends of the rack of the hydraulic machine are respectively provided with a first slide seat and a second slide seat, the first slide seat is connected with a first cylinder of the hydraulic machine, the second slide seat is connected with a second cylinder of the hydraulic machine, and the first and second slide seats are provided with mould replacing wheel discs; and the top of the rack of the hydraulic machine is also provided with a clamping device for an axle tube. The axle tube extrusion moulding equipment provided by the invention has high production efficiency and has the advantages of high product processing accuracy, good integral mechanical property and stable product quality compared with the traditional hot spinning process. A steel pipe blank is directly moulded at axle heads at the two ends in an extruding way by virtue of the hydraulic machine, and various welding defects existing in subsection moulding are avoided, thus the bearing capacity of a car axle is greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipe extrusion forming, more specifically, to an extrusion forming equipment and a forming method of a semi-trailer axle tube. Background technique [0002] The axle of the semi-trailer is a thin-walled shell-shaped part. The middle part of the part is rectangular or cylindrical, with equal wall thickness and long length; the two ends are circular pipe sections with variable diameter and variable wall thickness with the same shape and short length; The end and the middle rectangular section are connected by a square-circle transition section. At present, the structure commonly used in the axle industry is an integral forging structure. Because the whole part has the characteristics of slenderness, hollowness, responsible shape and uneven wall thickness, and the left-right symmetry of the axle makes it difficult to form the part as a whole. The axle forming process of most axle factories is to first proce...
