Horizontal clamping conveyer of Pilger rolled tube unit

Abstract

The invention discloses a horizontal clamping conveyer, comprising a base which can move; and at least two clamping mechanisms, wherein one of the clamping mechanisms is independent to clamp, and the clamping mechanisms are installed on the base. The invention has the advantages that each clamping mechanism provided by the invention independently operates the openness of the clamp so as to clamp objects in different outer diameters respectively so that the clamping reliability is greatly improved. For the clamping mechanisms are installed on the base and move along with the base, after the clamping mechanisms clamp the objects and convey the objects, the clamping mechanisms are in a same horizontal position so as to ensure that the objects clamped and conveyed will not incline in the horizontal direction.

Description

technical field [0001] The invention relates to production equipment of seamless steel pipes, in particular to a device for transporting capillary pipes in a pilger rolling mill. Background technique [0002] The pilger pipe rolling mill is an important equipment in the production of seamless steel pipes. Its function is to thin the pipe wall of the perforated hollow capillary pipe and control the wall thickness of the inner and outer diameters. The pilger pipe mill is divided into two methods: online mandrel threading and offline pre-piercing mandrel. Among them, offline prepiercing mandrel is widely used because it can greatly save auxiliary time. On the pilger unit of off-line pre-threaded mandrel, the capillary tube with pre-threaded mandrel needs to be transported from the pre-threaded line to the front of the rolling mill. Such as figure 1 As shown, when transporting the capillary 3 pre-piercing the mandrel 4, the capillary 3 must be transported horizontally to prev...

AI Technical Summary

Problems solved by technology

All the clamps 6 on the traditional manipulator have the same opening and closing degree, but the capillary 3 and the mandrel 4 have different outer diameters, which leads to the failure of some clamps 6 to be clamped, and the horizontal inclination will also occur. Since the pilger ring 5 is a loose sleeve It is on the mandrel 4, so it often causes the Pilger 5 ring to fall off, and the work cannot be completed, which reduces the work efficiency and increases the workload
