Problems solved by technology
[0005] However, in the prior art, since the two upper straight rollers and the chucks are respectively connected with two groups of hydraulic devices, when the hydraulic device applies pressure to the chucks, a misalignment will occur between the two chucks, so that the two upper Lateral movement of the position of the straight rolls, which eventually leads to poor performance of the entire upper straightening roll unit and lower bending roll unit for single straightening of the metal strip

The invention provides an upper straightening roll device which comprises a rectangular base, hydraulic devices arranged at the end part of both ends above the base, two first chucks and two second chucks arranged below the base, and two upper straight rolls which are respectively clamped by the first and second chucks, wherein the first and second chucks are connected with the hydraulic device through a connecting piece. The upper straightening roll device further comprises convex guide plates at the edges of the first chucks and concave guide plates at the edges of the second chucks, wherein the convex guide plates are connected with the concave guide plates in a locking manner. Malposition between the first and second chucks is effectively prevented by way of arranging the convex and concave guide plates which are connected in the locking manner at the edges of the first and second chucks, so that the single straightening effect of the whole upper straightening roll device on metal strips is improved.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to an upper straightening roller device applied in a slitting machine. Background technique [0002] Slitting machine, also known as slitting line, slitting machine, and slitting machine, is a name for metal slitting equipment. It is suitable for longitudinal shearing of metal strips and rewinding the slit strips into rolls. It has the characteristics of convenient operation, high cutting quality, high material utilization rate, stepless speed regulation of cutting speed and so on. [0003] Its main working steps are composed of unwinding, unwinding, leading material positioning, slitting, coiling, winding and so on. Usually, the applicable materials of slitting machine include tinplate, silicon steel sheet, aluminum strip, copper, stainless steel plate, galvanized plate and so on. It is widely used in many industries, including transformers, motors, home appliances, automo...
