An automatic loading and unloading device for off-line rolling pipe plugs

Abstract

An automatic loading and unloading device for off-line pipe rolling plugs belongs to the technical field of seamless steel pipe production devices. The device includes a rotating chuck mechanism, a mandrel locking mechanism and a pushing mechanism. One end of the cone of the plug is detachably engaged with the rotating chuck. On the disc mechanism, the tail of the plug is fixedly connected with the head of the mandrel, the mandrel locking mechanism locks the tail of the mandrel, the mandrel locking mechanism is installed above the push mechanism, and the push mechanism drives the mandrel locking mechanism to drive the core. The rod and the plug move along the axis direction, and several mandrel brackets are arranged below the mandrel between the rotary chuck mechanism and the mandrel locking mechanism. The device can realize the clamping and fixing of the plug and the mandrel regardless of whether the position of the plug and the mandrel is in an accurate position; the device is simple to operate, has a high degree of automation, improves the production efficiency and quality of the steel pipe, and can greatly reduce the labor intensity of workers, It reduces the risk factor of workers' work, and has good promotion and practical value.

Description

technical field [0001] The invention belongs to the technical field of seamless steel pipe production devices, and particularly relates to an off-line rolling pipe plug automatic loading and unloading device. Background technique [0002] In the production of existing seamless steel pipes, whether it is cold rolling or hot rolling, except for a few hot extrusion units that use pressure punching, basically all the first step deformation rolling is realized by skew rolling and piercing. The rolling deformation from solid billet to hollow billet directly provides qualified piercing capillary for the subsequent pipe rolling mill. After the plug is rolled with the mandrel for a certain number of times, the plug and mandrel will be worn to a certain extent. Through the device for automatic loading and unloading of the mandrel - "an automatic loading and unloading manipulator for rolling mandrel" (application number: 202010109442.5) will The mandrel with the mandrel is removed, an...

After the plug is worn and rolled with the mandrel for a certain number of times, the plug and the mandrel will be worn to a certain extent. Through the device for automatically loading and unloading the rolling mandrel - "A Manipulator for Automatic Loading and Unloading of the Rolling Mandrel" (Application No.: 202010109442.5) will The mandrel with the plug is removed, and the working characteristics of removing the plug during the production of seamless steel pipes in the workshop are: after the end of the rolling of the tube, the plug comes out with the mandrel, and when it needs to be replaced due to processing wear, many operators are required to do it manually. The disadvantages of removing the plug are: high production cost, more time for manual plug replacement, low degree of automation, high labor intensity, low work efficiency, high risk factor, etc., so it is urgent to develop a new type with high degree of automation. The mechanism of off-line loading and unloading of rolled pipe plugs for plug replacement
