Universal rolling mill with structure for preventing pull rod of guide and guard beam from warping in roll changing process

Abstract

The invention provides a universal rolling mill with a structure for preventing a pull rod of a guide and guard beam from warping in a roll changing process, which comprises an operation side bracket and a transmission side bracket which are arranged on two sides of a roll, and further comprises the guide and guard beam, the guide and guard beam is used for fixing a guide and guard device, and the guide and guard device is used for correcting the position of a rolled piece; the two ends of the guide beam are erected on the operation side support and the transmission side support respectively. The operation side support and the transmission side support are provided with a first through hole and a second through hole respectively. The two ends of the guide and guard beam penetrate through the first through hole and the second through hole. A counter bore used for containing the supporting assembly is formed in the opening portion, close to one end of the second via hole, of the first via hole, and the supporting assembly is embedded into the counter bore. The universal rolling mill with the structure for preventing the pull rod of the guide and guard beam from tilting in the roll changing process has the beneficial effects that the copper sleeves are additionally arranged at the guide and guard beam mounting positions of the left bracket and the right bracket on the operation side and are used for supporting and positioning the guide and guard beam, so that the phenomenon of tilting of the guide and guard beam is prevented.

Description

technical field [0001] The invention belongs to the field of rolling mills, and in particular relates to a universal rolling mill with a structure for preventing guide and guard beam tie rods from warping during roll changing. Background technique [0002] The universal rolling mill is an important piece of equipment on the steel rolling production line, and changing the rolls of the rolling mill rolls is a common operation. The guide beam tie rod of the existing universal rolling mill locks the drive side and the operation side bracket through the washer nut, and the nut is removed when changing the roll, and the drive side and the operation side bracket are separated by the roll change manipulator, so that the guide beam pull rod is pulled out, Then replace the rolls, but since the installation requires a large gap between the guide beam pull rod and the upper holes of the brackets on the operation side and the transmission side, after the roll change is completed, install...

Problems solved by technology

The guide beam tie rod of the existing universal rolling mill locks the drive side and the operation side bracket through the washer nut, and the nut is removed when changing the roll, and the drive side and the operation side bracket are separated by the roll change manipulator, so that the guide beam pull rod is pulled out, Then replace the rolls, but since the installation requires a large gap between the guide beam pull rod and the upper holes of the brackets on the operation side and the transmission side, after the roll change is completed, install the guide beam pull rod and the operation side bracket first. The tie rods of the guard beams will tilt their heads, which will make it very inconvenient to install the drive side brackets. In addition, there are four pieces of the same tie rods for each universal rolling mill. This problem makes the installation and debugging of the roll system extremely cumbersome and inefficient. , time-consuming and labor-intensive, so it is necessary to improve the structure of the universal rolling mill roll change to prevent the head of the guide beam tie rod from warping
