Abstract

The invention relates to a roller changing mechanism of a straightener. The roller changing mechanism comprises a support body, a movable device on the support body and a positioning device connectedwith one end of the support body; a hydraulic lifting platform is arranged at the lower end of bases, rollers are arranged at the lower end of the hydraulic lifting platform, a clamp used for fixing the base is arranged on the hydraulic lifting platform, the base is fixedly arranged on the lifting platform through the clamp. According to the roller changing mechanism, a movable and positioning roller changing mechanism is fastened and connected through a support sliding plate and a base sliding plate to achieve barrier-free sliding, the roller replacement multi-station position conversion is rapid and stable. A limiting device is arranged on the base to guarantee the accurate position of each station and then is locked by a column pin. The support and the base can realize fastening connection, and the rigidity of the whole straightener roller changing mechanism can be ensured.

Description

technical field [0001] The invention belongs to the field of straightening machines, and relates to a roll-changing mechanism, in particular to a fast-moving and accurate-positioning roll-changing mechanism on a tube and bar straightening machine. Background technique [0002] In the straightening machine industry, there are parallel roller straightening machines, mainly for plates and profiles. In addition, tube and bar straightening machines or oblique roller straightening machines are common. The development history of two-roll straightening is relatively long, and its design The method has also gone through a long and much process. At the beginning, it was the single arc design method, and then the arc fitting method was improved on this basis, and the middle is a single arc, and the two sides are tangent to the arc. Straight line method and so on, this is the first stage; the second stage is that the concave roller adopts a single arc method, while the convex roller ado...
