Technical Field

The utility model relates to the field of straightening equipment, in particular to a copper pipe rod straightening and positioning assembly.

Background

The straightening of copper pipe and bar is an important processing technology, and aims to eliminate the deformation such as bending, twisting and the like generated in the production, transportation or processing process, so that the copper pipe and bar meets the requirement of specified straightness. The common pressure straightener mainly comprises a machine body, a workbench, a pressure head, a power system and the like. The working principle is that the pressure is applied to the copper pipe and the copper bar through the pressure head, so that straightening is realized.

In the current production process, we find that long positioning wires are usually required to be arranged on two sides of a pressure head for positioning and supporting a relatively long copper pipe copper rod, so that the copper pipe copper rod is prevented from deviating and is prevented from being bent by gravity.

However, this method has a great problem. Firstly, the positioning lines increase the complexity of the equipment, which increases the manufacturing and maintenance costs of the equipment, and secondly, the positioning lines may wear or be damaged, which reduces the accuracy of the straightening and even affects the normal operation of the equipment.

The main innovation of the utility model is that the idler 6 is movable. When the copper pipe straightening device works, a long copper pipe copper rod to be straightened is placed on the left moving frame 1, one end of the copper pipe copper rod is guaranteed to be located under a pressure head, then the copper pipe copper rod is gradually transferred to the right moving frame 2 along with the straightening of a part of the copper pipe copper rod, and in the process, the left moving frame 1 and the right moving frame 2 can adjust the supporting positions according to the distance that the copper pipe copper rod extends out of two sides of the pressure head, so that the copper pipe copper rod is prevented from being bent by gravity.

In the design, dynamic support can be formed through the movement of the carrier roller 6, so that support at different positions can be realized according to specific conditions of copper pipe and copper bar, and the whole straightening process is adapted to the change.
