Bus bar rolling structure

Abstract

The invention discloses a bus bar rolling structure. The bus bar rolling structure comprises a support; the support is connected with an upper rolling wheel module and a lower rolling wheel module; a fixing block connected with the support sleeves the lower rolling wheel module; the upper rolling wheel module is provided with a lifting module. According to the characteristics of bus bar rolling work, the rolling structure has the advantages of reducing rolling errors caused by changes of gaps between rolling rings of upper and lower rolling wheels and improving the processing quality by reasonable structural improvements and especially by lifting motion of the overall upper rolling wheel module, relative fixation of the lower rolling wheel module and a design that the upper rolling wheel module is controlled to move up and down by the lifting module.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a rolling structure applied to the processing of busbars. Background technique [0002] The bus strip is a kind of welding strip, generally used as a bare conductive part, installed on an insulator, collecting current from the power supply, and then distributing the current to the output feeder, used to connect the previous battery slices connected in series, usually used in the photovoltaic industry. Generally, the confluence belt is processed from bare copper. Specifically, the upper calendering wheel and the lower calendering wheel of the calendering structure are compressed to the copper material together, and the round copper material is rolled and formed, that is, the upper calendering wheel and the lower calendering wheel are respectively lifted and rolled. The action of the screw applies pressure to the copper. In practice, it has been found that the rolling structure wi...

Problems solved by technology

In practice, it has been found that the rolling structure with this design will cause the force direction of the upper calender wheel and the lower calender wheel to be uncoordinated due to the relative sliding misalignment between the support and the mechanism frame, which directly leads to the thickness of the rolled product. Large size fluctuations lead to defective products

In addition, the common rolling structure uses the upper calender wheel and the lower calender wheel as the power transmission mechanism respectively through the synchronous pulley, gear and coupling, which not only further leads to inconsistent rotation speeds of the upper calender wheel and the lower calender wheel, but also leads to The deviation of the torque on the motor relative to the output torque of the motor is large, that is, the torque transmission efficiency is low
