Stretch straightening machine and stretch straightening method

Abstract

The invention discloses a stretch straightening machine and a stretch straightening method. The stretch straightening machine comprises a primary stretching device and a secondary stretching device, wherein the primary stretching device comprises a primary machine base and a guide rail supporting slide base arranged on the primary machine base, and a primary stretching chuck sliding with a single degree of freedom and a stretching oil cylinder for driving the primary stretching chuck to slide are arranged on the guide rail supporting slide base; slide rails which are matched with one another are arranged between the guide rail supporting sliding base and the primary stretching chuck; the secondary stretching device comprises a secondary machine base, and a secondary stretching chuck for clamping section bars is arranged on the secondary machine base; a first jaw and a second jaw for fixing the section bars are correspondingly arranged on the opposite side surfaces of the primary stretching chuck and the secondary stretching chuck; the primary stretching chuck further comprises a straightening channel which comprises a straightening clamping opening. The straightening machine and the straightening method disclosed by the invention can be used for performing pre-straightening and stretch straightening in sequence, thereby achieving a relatively good straightening effect and guaranteeing high precision; during the operation, only one ends of the section bars need to be put into the straightening machine, and thus the straightening machine is convenient to use.

Description

technical field [0001] The invention belongs to the field of stretching and straightening of aluminum profiles, and relates to a stretching and straightening machine and a stretching and straightening method. Background technique [0002] In the post-processing area of ​​aluminum profile extrusion production, the aluminum profile needs to be stretched and straightened to eliminate the bending and twisting of the aluminum profile, and at the same time eliminate the uneven stress of the aluminum profile along the cross-sectional direction. However, large-scale straightening machines also have problems such as poor straightening accuracy. And when in operation, the two ends of the profile need to be clamped respectively with stretching chucks respectively, the profile is usually long, and it is difficult for one person to operate. Contents of the invention [0003] In view of this, the object of the present invention is to provide a stretching straightening machine and a str...

AI Technical Summary

Problems solved by technology

However, large straightening machines still have problems such as poor straightening accuracy.

In addition, during operation, both ends of the profile need to be clamped with tensile chucks respectively. The profile is usually long and difficult to operate by one person.
