Description

Cylinder device of bar pinch roll Technical Field The utility model belongs to the technical field of steel rolling equipment, and particularly relates to a cylinder device of a bar pinch roll. Background Pinch rolls play a very important role in the stable production of a rolling line, typically by using two high-speed rotating collars to clamp the product with appropriate clamping force. At present, the clamping action of the pinch roll is realized through an air cylinder device, and the opening degree value of the pinch roll is adjusted according to the air cylinder device so as to adapt to the requirements of clamping bars with different diameters. But the existing cylinder device can not adjust the stroke of the cylinder device in the use process, and the stroke is adjusted only by the piston rod of the cylinder device, so that when the stroke to be adjusted is longer, the cylinder device with higher response speed is needed to clamp the bar, and the cylinder device is definitely required to be provided with higher requirements, and the production cost is increased. Disclosure of utility model Therefore, the utility model aims to provide a cylinder device of a bar pinch roll, so as to solve the technical problem that the existing cylinder device is slow in response speed and cannot be matched with bar clamping requirements with long adjusting stroke. In order to achieve the aim, the utility model provides the technical scheme that the cylinder device of the bar pinch roll comprises a cylinder support, a cylinder body, a piston rod, a piston, an adjusting nut and an adjusting rod, wherein the cylinder body is arranged on the cylinder support, the piston rod is arranged on the cylinder body and is arranged in a hollow mode, the piston is sleeved on the piston rod and is fixedly connected with the piston rod, the adjusting nut is fixedly arranged on the piston rod, one end of the adjusting nut penetrates through the piston rod, the adjusting nut is sleeved on the adjusting rod, and an air inlet and an air outlet which are communicated with the cylinder body are arranged on the cylinder support.
