Abstract

The invention discloses an oil-pressure type steel pipe draw-bench, comprising a rack, wherein the rack comprises an auxiliary rack and a main rack; a core rod subassembly is mounted on the auxiliary rack; the core rod subassembly includes a core rod trolley and a core rod which is mounted on the core rod trolley; the core rod trolley can move on the auxiliary rack back and forth; a drawing die subassembly is mounted on one side, close to the auxiliary rack, of the main rack; an oil hydraulic cylinder is mounted on the other side, far away from the auxiliary rack, of the main rack; a drawing trolley which can move on the main rack back and forth is mounted on the main rack; the movement of the drawing trolley relative to the main rack is driven by the oil hydraulic cylinder; and a charging device and a discharging device are respectively mounted on the two sides of the main rack. The oil-pressure type steel pipe draw-bench has the functions of automatic charging, drawing and discharging, is high in automation degree and stable in drawing, and can guarantee the drawing precision.

Description

technical field [0001] The invention relates to the field of steel pipe processing equipment, in particular to a steel pipe drawing machine. Background technique [0002] In mechanical processing, there are many machining methods for steel pipes, such as stamping, forging, rolling, rolling, bulging, and drawing. Among them, drawing is especially suitable for small-diameter, high-quality seamless steel pipes. Steel pipes must be obtained by cold drawing or cold rolling techniques. For the cold drawing processing of steel pipes, the commonly used tooling equipment is a chain or hydraulic drawing machine. [0003] The chain drawing machine is divided into two types: single chain drawing and double chain drawing. The general single chain drawing machine includes a fixed frame and a chain transmission mechanism driven by a motor and a reducer. On the transmission chain A drawing trolley is equipped with it, and a hydraulic clamp for clamping the outer wall of the steel pipe is ...
