Embodiment Construction
[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0017] Such as figure 1 As shown, the present invention is arranged symmetrically on the outside of the left pressure roller system and the right pressure roller system. Roller 6 is formed, and the present invention is used for pulling the side pressure roller pressing assembly 5 in left pressure roller system, right side pressure roller system.
[0018] Such as Figure 1 to Figure 5 As shown, the middle roll 8 and the work roll 7 are arranged in parallel and installed on the middle roll bearing housing 1 respectively, the work roll 7 is located directly under the middle roll 8; the left pressure roll system and the right pressure roll system are symmetrically arranged in the middle The left and right sides of the roller 8 are kept parallel to the middle roller 8, and the side pressure roller pressing assembly 5 is mainly composed of a hanger 10, a large brac...

The invention relates to an oblique drawing device for side pressing roll systems of a cold-rolling mill. The device is symmetrically arranged outside a left side pressing roll system and a right side pressing roll system for drawing side pressing roll compaction components in the left side pressing roll system and the right side pressing roll system. The oblique drawing device is characterized by comprising an eccentric mounting shaft, a tension spring, a mounting shaft and a locking nut; the eccentric mounting shaft is arranged on a middle roll bearing pedestal and is screwed and fixed through the locking nut, the end part of the eccentric mounting shaft is eccentrically provided with an eccentric pothook head, and a pothook at one end of the tension spring is hooked on the pothook head; and the mounting shaft is fixed on the side pressing roll components, the end part of the mounting shaft is provided with a pothook head, a pothook at the other end of the tension spring is hooked on the pothook head, and the tension spring is in a tension state. The oblique drawing device has a skilful and reasonable structure, and can greatly reduce the labor intensity and complexity during exchanging working rolls, reduce the time for exchanging the working rolls and effectively avoid the condition of damaging the rolling mill due to roll exchange.
Description
technical field [0001] The invention relates to an auxiliary equipment of a cold rolling mill, in particular to a side pressure roller system oblique tension device of a cold rolling mill. Background technique [0002] The 18-high rolling mill adopts a tower-shaped roll system, and the diameters of the work rolls used are all small; the roll system is symmetrically arranged in two closed door-shaped archways. . [0003] Since the center of gravity deviates from the support shaft of the side pressure roller pressing assembly, the side pressure roller mechanism tightly presses the work roll sideways. While the rolling mill often needs to replace the work rolls when it is in use, the operation process of the traditional 18-high rolling mill to replace the work rolls is generally as follows: the manual operation control system lifts the rolling mill compression oil cylinder, drags out the rolling mill roll system; manually enters and discharges the material Use a crowbar on th...
