Synchronous tension regulating device of slitting line

Abstract

The invention discloses a synchronous tension regulating device of a slitting line. The synchronous tension regulating device comprises a spindle installed on an upper base in a tension generating device of the slitting line. The two ends of the spindle are connected with a first gear and a second gear correspondingly. A first support and a second support are arranged on the two sides of the upper base correspondingly. A first rack is arranged on the first support. The first support is connected with a first upper ejector block and a first lower ejector block. The first upper ejector block is connected with a first upper jackscrew. The first upper jackscrew is connected with a first upper nut. The first lower ejector block is connected with a first lower jackscrew. The first lower jackscrew is connected with a first lower nut. A second rack is arranged on the second support. The second support is connected with a second lower ejector block. A second upper ejector block is connected with a second upper jackscrew. The second upper jackscrew is connected with a second upper nut. The second lower ejector block is connected with a second lower jackscrew. The second lower jackscrew is connected with a second lower nut. By the adoption of the synchronous tension regulating device, the effect that the upper base of the tension generating device of the slitting line is uniformly pressed on a material strip in a parallel mode is guaranteed, and a perfect tension generating effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of slitting machine set tension, and in particular relates to a synchronous adjustment device for the tension of a slitting machine group. Background technique [0002] At present, in the metallurgical slitting industry, in the process of coiling the strip, the construction of the sheet is a difficult problem. There are many reasons for this: the material characteristics of the strip, the quality and accuracy of the equipment, the completeness and rationality of the hydraulic system design, and the level of manual operation will all affect the effect of the strip construction, which will eventually lead to the stripping after slitting. Untidy and uneven quality. The main reason is that when the upper seat of the construction and tensioning device presses down the material through the oil cylinder, whether it is the action of one oil cylinder or two, the pressure is not uniform.
