Technical Field

[0001] The utility model relates to the field of upper support roller replacement of a skin-pass machine, in particular to a support roller balancing device for a skin-pass machine. Background Art

[0002] The support roller balancing device is used to realize the lifting function of the upper support roller during the roller changing process of the skin-finishing machine. The traditional roller changing device has the following problems:

[0003] (1) There are two oil cylinders on the top of the transmission side and the operating side arch, a total of four oil cylinders are used to drive the upper support roller to rise and fall. The four oil cylinder levers are directly hung on the upper support roller bearing seat. When they rise and fall at the same time, it is difficult to ensure the synchronous rise and fall of the four cylinders, and the roller lifting is prone to an unstable state.

[0004] (2) The rod chamber lifts the oil cylinder at the bottom, and the rod chamber output lifts the upper support roller, which wastes the capacity of the oil cylinder.

[0005] (3) In order to control the displacement synchronization of the four cylinders, the cylinders are usually equipped with displacement sensors to ensure cylinder synchronization, which is costly, prone to failure, and more troublesome to maintain.

[0006] Therefore, it is necessary to design a new balancing device for the support roller of the skin-finishing machine to overcome the above problems. Utility Model Content
