Brake system for tensioning and straightening rollers

Abstract

The invention discloses a braking system for a deviation correcting roller of a stretching and straightening line. The brake system is used to fix the deviation correction roller when the strip is cut, including: stop disc, clamping part and power module; the stop disc is fixedly connected with the deviation correction lower roller of the deviation correction roller; the clamping part is used for The moving disc performs braking; the power module is connected with the clamping part, and is used to drive the clamping part to act, so that the clamping part clamps the stop disc to realize the braking of the stop disc. The braking system of the deviation correction roller of the tensioning and straightening line of the present invention fixes the stop disk on the deviation correction lower roller, and uses the clamping part and the power module to brake the stop disk, so that the deviation of the deviation correction can be stopped when the strip is sheared. The lower roller is fixed to reduce the sinking and backward displacement of the strip due to its own weight, prevent the strip from being unloaded on the disc shears, ensure the shearing accuracy of the disc shears, and reduce the gap between the strip slices .

Description

technical field [0001] The invention relates to the technical field of strip steel production equipment, in particular to a braking system for deviation correcting rollers of a tension and leveling line. Background technique [0002] The tension-leveling line belongs to the continuous production unit, which is used to separate the cold-rolled strip coils after being stretched, bent, straightened and trimmed. It will not stop in the coiling or unloading process section. figure 1 A partial structural schematic diagram of a tension leveling wire in the prior art is provided as an example. as attached figure 1 As shown, the existing tension and leveling line includes disc shears X1, correction roller X2 and tension roller X3. Since the correction roller X2 does not need to be threaded and fed, the correction roller X2 is usually composed of two rubber rollers that can be clamped freely. Realize the deviation correction function. When the strip Z is cut by manual jog feeding, ...

AI Technical Summary

Problems solved by technology

When the strip Z is cut by manual jog feeding, the tension of the strip Z will drop to zero instantly, because the tension section of the strip Z is from the deviation correction roller X2 next to the entrance of the disc shear X1 to the tension roller X3 at the exit of the rear looper. One section, at this time, the strip steel Z will sink due to its own weight, and then the strip steel Z will be unloaded at the disc shear X1; When Z passes through the disc shear X1 again, the incision of the strip steel Z is not at the position corresponding to the original knife edge, which will lead to a large gap between the strip slices, which reduces the shearing accuracy of the tension leveling disc shear X1 and affects product quality
