[0002] In the current manufacturing industry, cold and hot roll bending machines are important production equipment and are widely used in the forming of various metal sheets. However, the roll bending machines commonly used at home and abroad are all single-flow designs, and the axial adjustment mechanism of the working roll ring mainly relies on a reduction motor, which drives two spiral elevators synchronously through a steering gear, and the other end of the spiral elevator is connected to the roll ring, thereby driving the roll ring assembled on the working shaft to move along the axial direction of the working roll, so as to achieve the purpose of adjusting the working roll ring. Although this adjustment method can meet production needs to a certain extent, it has problems such as low adjustment efficiency, high labor intensity, and high consumption of spare parts.

[0003] With the increasingly fierce market competition, improving production efficiency and reducing production costs have become important goals pursued by enterprises. Therefore, in view of the shortcomings of existing technologies, it is particularly important to develop a new type of roll bending unit that can greatly improve production efficiency, reduce the production intensity of workers, and reduce the consumption of spare parts. Against this background, the double-flow hot roll bending unit came into being. Compared with the single-flow design, the double-flow design has significantly improved production efficiency. However, the axial adjustment mechanism of the working roll ring of the double-flow unit also faces technical challenges.

[0004] In order to meet the market demand for efficient and low-consumption production, it is urgently necessary to propose a new axial adjustment design scheme for the roll ring of the double-stream hot roll bending working roll, so as to realize the fast and accurate adjustment of the roll ring of the double-stream hot roll bending working roll, reduce the production intensity of workers, reduce the consumption of spare parts, and improve the roll ring adjustment efficiency. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an axial adjustment device for a double-stream hot roll bending working roll, so as to realize fast and accurate adjustment of the roll ring of the double-stream hot roll bending working roll, reduce the production intensity of workers, reduce the consumption of spare parts, and improve the roll ring adjustment efficiency.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The beneficial effects of the present invention are:

[0009] The present invention provides an axial adjustment device for working rolls of a double-stream hot roll bending machine, and provides an axial adjustment mechanism for axially adjusting the working rolls of a double-stream hot roll bending machine set. The device adopts a structure in which an inner roll ring adjustment mechanism, a central roll ring adjustment mechanism and an outer roll ring adjustment mechanism cooperate to axially adjust the inner roll ring, the central roll ring and the outer roll ring, respectively, thereby greatly reducing the number of roll ring spare parts and greatly saving the area of ​​the factory building occupied by the spare parts.

[0010] Secondly, the axial adjustment device of the double-flow hot roll bending working roll has a simple structure and fast adjustment speed, which greatly reduces the time for adjusting product specifications and can greatly reduce the production intensity of workers.
