Radial synchronous-adjusting mechanism for roller of pipe mill

Abstract

The invention provides a radial synchronous-adjusting mechanism for the roller of a pipe mill, so as to solve the problems, in the prior art, that the effect of roller adjusting is bad, the product qualification rate is low during mass production of pipes, and a novel structural way is required for radial adjustment to rolling pipe diameter; the invention adopts the technical point that a mounting framework is fixed on the upper surface of a frame, an inclined wedge mechanism is fixed at the lower part of the mounting framework, a five-rod mechanism is arranged above the inclined wedge mechanism and fixed in the middle of the mounting framework, and three roller mechanisms are further mounted on an arc-shaped inner side formed by the surrounding of the five-rod mechanism; the radial synchronous-adjusting mechanism provided by the invention has the positive effects as follows: adjustment to radial positions of the rollers can be achieved according to needs, so as to meet the requirements of producing different products, the rollers can be contracted and released at the same time through the five-rod synchronous mechanism, radial positioning is accurate, and the product qualification rate is ensured; the invention further has the characteristics of high control degrees, low cost, stability, reliability and stronger practicability and the like.

Description

technical field [0001] The invention relates to the field of pipe rolling mills, in particular to a radial synchronous adjustment mechanism for rolling pipe mill rolls which simultaneously radially adjusts three rolls. Background technique [0002] In order to control the radial size of the tubular product, the pipe rolling mill must be equipped with a radial adjustment mechanism and an axial adjustment mechanism, and the radial adjustment is used more frequently. There are two types of radial adjustment mechanisms in existing pipe mills. One is to adjust each roll in one direction. This method is complicated to operate, takes a long time, and the adjustment accuracy is low; Two of the rollers are adjusted in the radial direction, and one roller is adjusted separately to realize the adjustment of the diameter of the rolled tube. [0003] The debugging of the above two methods is very difficult, the debugging effect is poor, and the qualified rate of the product is low when ...

Problems solved by technology

There are two types of radial adjustment mechanisms in existing pipe mills. One is to adjust each roll in one direction. This method is complicated to operate, takes a long time, and the adjustment accuracy is low; Two of the rollers are adjusted in the radial direction, and one roller is adjusted separately to realize the adjustment of the diameter of the rolled pipe

[0003] The debugging of the above two methods is very difficult, the debugging effect is poor, and the product qualification rate is low when the pipe is mass-produced, so a new structural method is needed to realize the radial adjustment of the rolling pipe diameter
