A calibration device for the bending roll of the hot coil box that can be automatically fed into the spacer

Abstract

The invention discloses a hot coil box bending roller calibration device capable of realizing automatic feeding of a cushion block. The hot coil box bending roller calibration device comprises an inlet bending roller, an outlet bending roller, a middle guide plate, cushion blocks, a lower bending roller and two cushion block feeding devices, wherein the inlet bending roller and the outlet bending roller are symmetrically arranged on the two sides of the middle guide plate respectively; the lower bending roller is arranged below the middle guide plate; the bottom of the lower bending roller is connected with a lifting cylinder; the two cushion blocks are connected through an arc-shaped connecting plate; the arc-shaped connecting plate is matched with the lower bending roller; the two cushion block feeding devices are coaxially arranged at the two ends of the lower bending roller; each of the cushion block feeding devices comprises a positioning roller and an arc-shaped push plate arranged at one end of the corresponding positioning roller; the arc-shaped push plates can move along the arc surfaces at the tops of the positioning rollers. With the adoption of the hot coil box bending roller calibration device, the cushion blocks can be automatically fed onto the lower bending roller to be positioned, manual operation is not needed, the safety is high, the calibration is accurate, the precision is high, and the calibration is normalized.

Description

technical field [0001] The invention relates to an auxiliary device in the production process of hot coils, which belongs to the technical field of continuous hot rolling, in particular to a calibration device for bending rolls of a hot coil box which can automatically feed pads. Background technique [0002] The hot coil box is the key process equipment to improve the quality of hot rolling products. The control of the bending roll directly affects the coil shape of the hot coil during the coiling process of the hot coil box. The accuracy of the initial zero position calibration of the roll gap directly affects the coil shape. The control accuracy and operation stability in the extraction process. Only when the calibration of the initial zero position of the bending roll is completed, the subsequent roll gap setting and roll gap change control can be carried out. [0003] Usually the bending roll calibration adopts the upper bending roll (two, one entrance bending roll and...

AI Technical Summary

Problems solved by technology

[0006] 1. The block is not easy to operate, and the staff is completely exposed to the range of equipment movement. The operation is very cumbersome and dangerous

[0007] 2. It takes a long time for the pressure relief to fall, and it takes about 40 minutes to complete one time; due to the insufficient pressure of the free fall of the bending roller, the existing mechanical gap cannot be fully eliminated

[0008] 3. Due to the difficulty in operation, the calibration work cannot be done regularly, which affects the reliability of the equipment
