Abstract
The utility model belongs to the technique of round-material straightening machines. In existing locking apparatus for straightening machine, oil-cylinder directly-moving type locking is adopted, namely, a hydraulic cylinder drives a braking head to support a roller seat, to cause that the roller seat can not be moved opposite to a machine frame; the friction coefficient of stiff contact is smaller, and locking effect is influenced. The utility model adopts a structure that the front end of the braking head, namely the contacting surface of the braking head and the roller seat is additionally provided with a flexible rubbing filler block to enlarge the friction coefficient of a contact surface, to cause that the area of a brake oil cylinder can be reduced half under an equal condition, and maneuvering performance is improved greatly.
Description
The utility model relates to the strengthening round section machine technology, mainly proposes a kind of cross-roll straightening machine locking device.
Along with the progress of domestic and international strengthening round section machine designing technique, improves flattening precision and production efficiency and become present developing direction, and the locking device on the strengthening round section machine is the mechanism of a key whether locking reliably directly influences flattening precision at present.That adopts now is designed to oil cylinder Direct Action Type locking device, and promptly hydraulic cylinder promotes the braking head and to cross roll seat roof pressure it can not be moved relative to frame.Facts have proved that this device mobility is better, control is simple, and processing and manufacturing also is easier to.But its rigidity braking head directly acts on the rigidity roller seat under hydraulic action, between coefficient of friction only be 0.15, therefore be restricted and system oil pressure is under the situation of definite value at the smoothing roll holder structure, satisfy the necessary condition of locking torque greater than this straightener steady operation of aligning roller seat flywheel moment, just can only finish by the diameter that increases locking cylinder, its mobility can weaken greatly thus.
Its purpose of the locking device that the utility model proposes is to solve the existing and of a specified duration an open question of said structure, and makes it have characteristics simple and reasonable for structure.
The utility model is finished the approach that its invention task takes: promptly brake at a braking front end of oil cylinder Direct Action Type locking device on the faying face of head and roller seat and install a flexible friction pad additional.Thereby change the rigidity way of contact in the past, the confficient of static friction between flexible friction pad and the rigidity roller seat is 0.3, is two ones of confficient of static friction between the steel to steel, therefore, install the flexible friction pad additional before the braking head after, the area of brake cylinder can reduce half, and mobility is improved naturally.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
With reference to accompanying drawing the utility model structure is described further:
As shown in drawings: smoothing roll 1 is fixed on the roller seat 2, and roller seat 2 is positioned at the rotatable angle of adjusting of relative frame on the frame 3, but needs relative frame 3 to fix when work, and can not be offset.Setting is by oil cylinder 8, piston 7 and braking 5 hydraulic locking apparatus that constitute, and hydraulic cylinder 8 installs sealing ring 6 positiver sealings additional.Braking 5 front end have a flexible friction pad 4, specifically can be asbestos plastic friction pad, thereby change the rigidity friction of in the past braking between head and the roller seat, improve the coupling mechanism force of braking head, experimental results show that this structure locking effect is fine and its structure is simple especially roller seat.
