AI Technical Summary
In the prior art, the upper straightening roller seat of the tube and bar inclined roller straightener has insufficient friction, resulting in poor locking effect between the roller seat and the sliding seat, which affects the straightening accuracy and causes the roller seat to wobble.
The upper roller seat is fixed by both a locking cylinder and a balancing cylinder. The piston diameter of the locking cylinder is larger than that of the balancing cylinder, which generates a greater tension force. The sliding seat and the upper roller seat cooperate with the protrusions and grooves to achieve a stable lock.
It improves the straightening accuracy of the straightening machine, solves the problem of roller seat wobbling, and is easy to process and install with low cost.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of metallurgical tube and bar straightening machine equipment, and mainly relates to a locking mechanism for the upper roller seat of a metal tube and bar inclined roller straightening machine. Background Technology
[0002] In the past, the upper straightening roller seat of the tube and bar inclined roller straightener used the pulling force of the two side balance cylinders to lock the upper plane of the roller seat and the lower plane of the upper sliding seat together, so as to generate friction between the two planes and thus lock the roller seat. This structure is limited by the size of the pulling force of the balance cylinder, resulting in insufficient friction between the roller seat and the sliding seat. It cannot overcome the rotational torque between the inclined straightening roller and the tube and bar, thus seriously affecting the locking effect, causing the roller seat to shake and affecting the straightening effect. Utility Model Content
[0003] To solve the above problems, the purpose of this utility model is to propose a locking machine for the upper roller seat of a metal tube and bar inclined roller straightening machine.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A locking mechanism for the upper roller seat of a metal tube and bar inclined roller straightener is disclosed. The two ends of the upper roller seat, used to fix the upper straightening roller, are respectively connected to the output ends of corresponding balance cylinders. Two balance cylinders are respectively fixed on the upper frame of the straightener. A sliding seat, coinciding with the center of the upper roller seat, is provided on the upper part of the upper roller seat. The two sides of the sliding seat are respectively fitted onto the columns of the metal tube and bar inclined roller straightener. The mechanism is characterized in that a locking cylinder is fixed in the middle of the sliding seat; the piston of the locking cylinder passes through the sliding seat and is fixedly connected to the upper roller seat, and the diameter of the piston of the locking cylinder is larger than the diameter of the pistons of the balance cylinders on both sides; the upper roller seat and the sliding seat are tightened together by the piston of the locking cylinder; the locking cylinder and the two balance cylinders together constitute the upper roller seat locking mechanism.
[0006] The upper roller seat has an upward protrusion in the middle of its upper end face, and the sliding seat has a groove that matches the protrusion. The cooperation between the protrusion and the groove allows the upper roller seat to rotate around the center of the sliding seat.
[0007] The piston of the locking cylinder is fixedly connected to the upper roller seat via a connecting sleeve.
[0008] This utility model proposes a locking mechanism for the upper roller seat of a metal tube and bar inclined roller straightener. Through the structural design of the locking cylinder between the middle of the upper roller seat and the sliding seat, the upper roller seat of the straightener can be firmly locked onto the sliding seat of the straightener. This solves the problem of the upper straightener seat shaking during the use of the straightener, improves the straightening accuracy of the straightener, and has the characteristics of convenient processing and installation and low manufacturing cost.
