Description

Anti-gnawing rail side wheel mechanism of aluminum profile straightening machine

Technical Field

The utility model belongs to the field of aluminum profile extrusion production lines, and relates to a rail gnawing prevention side wheel mechanism of an aluminum profile straightening machine.

Background

In the production line for conveying the extruded rear part of the aluminum profile, the online straightening machine is used for removing internal stress and correcting the profile deformed due to the internal stress after quenching. The principle is that after two ends of the section are clamped firmly by two jaws, the movable end jaw is fixed, and the stretching end jaw stretches the section by the force exerted by an oil cylinder to remove most internal stress and correct the shape.

When the stretching center of the jaw is coincident with the section center of the section, the jaw is in an ideal stress state, and the section, the vehicle body and the like in the stretching system are only pulled and have no torque. However, in actual production, the center of the section is a curve due to stress deformation of the section, and the distance between the stretching center of the jaw and the center of the section is caused by feeding position errors, so that torque is generated during stretching of a car body. In the common straightening equipment, because the movable end jaw does not move in the process of stretching the same batch of profiles, the movable repositioning is only carried out after the lengths of the profiles are changed, and because the stretching force is small in a medium-and-small-tonnage straightening machine, the bending moment is small, the friction damage to rails is small, and the like, the common Z-direction limiting is designed into a flange type.

The flange type structure has the advantages that due to the fact that a gap exists between the flange and the limiting support surface of the rail, the vehicle body can have a deflection angle, in a large-tonnage straightening machine, due to the fact that large tensile force is large in bending moment, and a gap exists between the bolt of the movable end jaw positioning mechanism and the rail hole, when the vehicle body is stretched, the flange of the vehicle body impacts the support surface of the rail along the inclination angle under the action of the tensile force, the flange rubs the support surface of the rail to form a strip-shaped gnawing mark similar to a feeding type of an end milling cutter, the service life of the rail is seriously shortened, and the risk of scrapping parts exists.
