AI Technical Summary
In the prior art, the straightening roller seat of the pipe rod inclined roller straightening machine is prone to wear and deform after long-term use due to the single-sided locking structure, causing the roller seat to shake and affect the straightening effect.
The straightening roller seat design is adopted for the metal tube rod inclined roller straightening machine. The lower part of the platform has a gradually expanded conical surface, which combines the double-sided locking cylinder and the conical surface friction copper pad to achieve a firm locking of the roller seat through radial and axial forces.
It improves the straightening accuracy of the straightening machine, solves the roller seat shaking problem, and reduces manufacturing costs.

Description
Technical Field
[0001] The utility model belongs to the technical field of metallurgical tube and bar straightening machine equipment, and mainly relates to a wedge-shaped locking mechanism for a roller seat of a metal tube and bar inclined roller straightening machine. Background Art
[0002] like Figure 1 As shown, the straightening roller seat 3 of the previous pipe and bar inclined roller straightening machine 1 adopts a single-sided locking cylinder 2 to press the cylindrical surface of the roller seat, so that the cylindrical surface cooperates with the upper copper sleeve 6 installed on the lower frame 1 of the straightening machine to generate friction, thereby playing the role of locking the roller seat; this structure is prone to cause unidirectional wear and deformation of the upper copper sleeve 6 after long-term use of the equipment, thereby seriously affecting the locking effect, causing the roller seat to shake, and affecting the straightening effect. Utility Model Content
[0003] In order to solve the above problems, the purpose of the utility model is to provide a wedge-shaped locking mechanism for the lower roller seat of a metal tube and bar inclined roller straightening machine.
[0004] The present invention adopts the following technical solutions to achieve the above purpose:
[0005] A wedge-shaped locking mechanism for the roller seat of a metal tube and bar oblique roller straightening machine, wherein the straightening roller seat of the metal tube and bar oblique roller straightening machine has a platform for supporting the straightening roller; the lower part of the platform has a raised cylinder integrally formed with the platform, and the raised cylinder is located in the lower frame of the straightening machine; it is characterized in that the middle section of the outer circumference of the raised cylinder has a conical surface with a gradually expanding diameter from top to bottom; locking cylinders are respectively provided on the corresponding two sides of the lower frame of the straightening machine; the piston head of the locking cylinder is set There is a conical friction copper pad that matches the conical surface on the straightening roller seat; the two locking cylinders jointly apply pressure to the conical surface of the straightening roller seat, and generate an embracing radial force and a downward axial force on the conical surface; the radial force causes the conical friction copper pad on the piston head of the locking cylinder and the conical surface of the straightening roller seat to generate friction to clamp the roller seat, and the downward axial force causes friction between the straightening roller seat and the plane that matches the lower frame of the straightening machine, which will press the straightening roller seat onto the lower frame of the straightening machine.
[0006] An upper copper sleeve and a lower copper sleeve are arranged between the raised cylinder of the straightening roller seat and the lower frame of the straightening machine.
[0007] The utility model proposes a wedge-shaped locking mechanism for the roller seat of a metal tube and bar inclined roller straightening machine. Through the structural design of the conical surface on the straightening roller seat and the double-sided locking cylinders, the straightening roller seat can be firmly locked on the lower frame of the straightening machine, thereby solving the problem of the straightening roller seat shaking after long-term use of the straightening machine, improving the straightening accuracy of the straightening machine, and having the characteristics of easy processing and low manufacturing cost.
