Problems solved by technology

However, this device adopts the linkage shaft arranged in the center to drive the circular pressure plate by the hydraulic cylinder, the uniformity of the force is poor, and the connection between the linkage shaft and the circular pressure plate is prone to lateral force; the driving of the circular pressure plate is controlled by manual observation. It may cause the circular pressure plate to not be pressed down properly, or to be pressed down too much; the equipment is easily damaged and the service life is not long

Embodiment 1

[0027] see figure 1 As shown, a strip steel coil tower shape elimination device is used to eliminate the tower shape generated when the strip steel coil 1 is coiled, and includes a pressure plate 2, a driving cylinder 3, a support 5 and a control system.

[0028] The upper side of the bracket 5 is provided with a mounting plate 51 , and the lower side of the bracket 5 is provided with a bottom plate 52 .

[0029] The cylinder block of the driving cylinder 3 is mounted on the mounting plate 51 through the flange 31 .

[0030] There are two guide mechanisms arranged symmetrically with respect to the piston rod of the driving cylinder 3. Each of the guide mechanisms consists of a guide sleeve 41 fixedly connected to the bracket 5 and a guide sleeve 41 fixedly connected to the pressure plate 2 and connected to the guide sleeve 41. A slidingly connected guide rod 42 is formed.

[0031] The telescopic direction of the piston rod of the driving cylinder 3 is the same as the sliding...

Embodiment 2

[0034] see figure 2 As shown, a strip steel coil tower shape elimination device is used to eliminate the tower shape generated when the strip steel coil 1 is coiled, including a pressure plate 2, a driving cylinder 3, a support 5, a carrier 6 and a control system.

[0035] The upper side of the bracket 5 is provided with a mounting plate 51 , and the lower side of the bracket 5 is provided with a bottom plate 52 .

[0036] The cylinder block of the driving cylinder 3 is mounted on the mounting plate 51 through the flange 31 .

[0037] There are two guide mechanisms arranged symmetrically with respect to the piston rod of the driving cylinder 3. Each of the guide mechanisms consists of a guide sleeve 41 fixedly connected to the bracket 5 and a guide sleeve 41 fixedly connected to the pressure plate 2 and connected to the guide sleeve 41. A slidingly connected guide rod 42 is formed.

[0038] The telescopic direction of the piston rod of the driving cylinder 3 is the same as...

Embodiment 3

[0053] The rest are the same as the second embodiment, the difference is that the setting positions of the first sensor 71 and the second sensor 72 are different from the second embodiment. side (can also be set on the same side as the case may be), and the height of the first sensor 71 from the stage 6 is slightly larger than the height of the strip coil 1, so as to detect whether the tower shape of the strip coil appears, and the distance from the second sensor 72 The height of the stage 6 is the same as that of the steel strip coil 1, both of which are photoelectric sensors that receive and emit photoelectric sensing signals in the horizontal direction.

[0054] The strip steel coil tower elimination method based on such setting comprises the following steps:

[0055] S1, the first sensor 71 detects the strip steel coil 1 in real time, if not detected, then continue monitoring, if the strip steel coil 1 is detected, then a first detection signal is formed, and enters S2;

Abstract

The invention discloses a device and a method for eliminating the turriform of a band steel roll. The device comprises a chuck, a driving cylinder and a bracket, wherein the chuck is driven by the driving cylinder and is connected with the driving cylinder, and the bracket is arranged on a cylinder body of the driving cylinder. The device is characterized in that at least two guide mechanisms which are symmetrically arranged relative to a piston rod of the driving cylinder are arranged, each guide mechanism consists of a guide sleeve and a guide rod, the guide sleeves are fixedly connected to the bracket, and the guide rods are fixedly connected to the chuck and are in sliding connection with the guide sleeves. Through the arrangement of the guide mechanisms, the chuck cannot be deviated under the influence of stress in the downwards pressing process, the balance of downwards pressing force is ensured, and the service life of the mechanisms is prolonged. The quality of the band steel roll can be accurately controlled by a sensor for detecting the band steel roll and the chuck, and the turriform of the band steel roll is fully automatically eliminated.

Description

technical field [0001] The invention relates to a device for adjusting the winding shape of a strip steel coil, in particular to a strip steel coil tower shape eliminating device and a eliminating method. Background technique [0002] Hot-rolled strip steel has good processing performance and is widely used in automobile, construction and other industries. The production method is to use the rolling mill to roll the steel below the recrystallization temperature. The major influence on the product quality during the strip coiling process is mainly the coiling tower shape. The coiling tower shape is divided into: internal tower shape, intermediate tower shape, external tower shape, overall tower shape, etc. The tower shape accounts for more than half of the entire coil waste. If the coil tower shape problem cannot be solved, it will have an impact on the product success rate, product quality and appearance. [0003] Chinese utility model patent CN201296566Y discloses a steel ...
