Description

Pipe shaping equipment

Technical Field

The invention relates to the field of pipe machining, in particular to pipe shaping equipment.

Background

The defects of outward protrusion and/or inward depression and the like on the surface of the pipe are eliminated by shaping when the pipe product is processed. When the battery shell is processed by using the existing pipe shaping equipment, the defects of outward protrusion and the like are eliminated or reduced by the outer side surface of the pipe in a rolling mode, the pipe can be internally inserted with a core rod to assist in shaping, and the side wall of the pipe is in close contact with the side surface of the core rod to prevent the side wall of the pipe from being inwards sunken when rolling. The tube and the core rod are mutually extruded when being rolled, so that the core rod and the tube are mutually separated and external force is required to be applied, on one hand, when the tube to be shaped is longer, the core rod and the tube are mutually separated difficultly, and therefore, when a battery shell is processed, the tube is generally cut into semi-finished products and then processed, and due to the processing mode, the semi-finished tube is required to be shaped one by one, so that the shaping cost is long and the efficiency is low when mass production is carried out; on the other hand, when the core rod and the pipe are separated from each other, the surface of the core rod and the inner surface of the pipe are mutually rubbed to cause the inner surface of the pipe to be worn, and the quality of a finished product is influenced. In addition, the side of the tube used by the battery shell needs to eliminate or reduce the defect of inward recess, but the existing shaping equipment can not effectively eliminate or reduce the defect of inward recess existing on the side of the tube, so that the tube after shaping can not be used, and waste is caused.
