Problems solved by technology

[0003] At present, the commonly used straightening machines have problems such as large volume, complex structure, inconvenient operation, and narrow application area. Especially when used for straightening small-sized narrow belts, not only the operation process of belt threading and adjustment is complicated, but also the difficulty of straightening control is increased. , equipment utilization efficiency is not high

Abstract

The invention relates to a small narrow band bending straightener and belongs to the technical field of metal bar straightening equipment. The straightener consists of straightening roll group mechanism positioned on an upper part, a bending roll group in the middle, a machine seat and a power mechanism at bottom and a control device, wherein the straightening roll group mechanism comprises a straightening roll group and a supporting and regulating device, and the straightening roll group consists of a straightening roll and a pair of pressing rolls; the bending roll group consists of two pairs of driving and driven bending rolls and a pressing roll; the power mechanism comprises a main driving motor and a transmission mechanism; the driving and driven bending rolls and the pressing roll are arranged on the back plate of the machine base through a rotating shaft cantilever, and the straightening roll and the pressing rolls are arranged on the supporting and regulating device by rotating shaft cantilevers; the main driving motor is connected with the rotating shaft of the driving bending roll through the transmission mechanism, the main driving motor is below a working platform panel, and the transmission mechanism is arranged behind the back plate of the machine frame; and the two motors are controlled by the control device. The straightener has the advantages that: band straightening speed and the relative positions of the straightening rolls can be regulated; the structure is simple and compact; the band insertion and operation are convenient; the straightening effect is good; and the like.

Description

Technical field [0001] The invention relates to a small-sized narrow-band tension-bending straightening machine, which belongs to the technical field of metal strip straightening equipment. Background technique [0002] In the process of rolling, extrusion, drawing, transportation and various processing, metal strips are often bent or twisted due to external forces, temperature changes and internal forces. For flat materials and narrow strips, it often appears as a wave bend in the vertical plane and a sickle bend in the horizontal plane. For narrow strips with bends, such as copper strips or aluminum strips, there will be uneven surfaces, uneven gaps between two adjacent turns, and inconsistent tension between upper and lower layers during winding, which directly affect product quality. Therefore, the metal narrow strip needs to be straightened before coiling and coiling, and the processing size of the metal narrow strip is not allowed to change and the metal structure is ...
