Abstract
The utility model relates to a locking mechanism of angle plane for inclined roll straightening machine, which comprises a locking oil cylinder, a locking pull rod, an inclined wedge and a fixing connection plate, and is characterized in that the inclined wedge is arranged between the oil cylinder and a locking plane, the oil cylinder force can be converted into the pull force of a rigid rod. The utility model relates to the angle adjustment of leveling roll from the inclined roll straightening machine and the locking device on the finishing mill equipment in metallurgical machinery, which is applicable to the leveler where roll-gap can be lifted up and pressed down quickly.
Description
Technical field
The utility model relates to the corner adjustment of cross-roll straightening machine smoothing roll and the locking device of one of finishing equipment in the metallurgical machinery, utilizes the frictional force on two or more planes to have in mechanism's locking of relative motion specifically.
Background technology
The smoothing roll corner of cross-roll straightening machine need be adjusted according to the diameter of aligning stocking, and corner must be locked after adjusting and could be worked.At present, common corner retaining mechanism is directly to adopt the pulling force locking of cylinder pressure at night or directly use the method for bolted on connection to compress, and also the pulling force of hydraulic cylinder is given the function of balanced controls weight sometimes in the locking of smoothing roll corner again.Its shortcoming is: owing to the frictional force of directly utilizing the oil cylinder pulling force to be produced between two planes, can be subjected to the influence that oil pressure changes, the strain of fluid pressure line existence simultaneously, the power of carrying outside additional also can cause the pull bar of oil cylinder to produce trace when surpassing the oil cylinder pulling force displacement, thereby cause that the smoothing roll corner changes, and influences the straightening quality of stocking.As the method that directly compresses with bolted on connection, not only the adjustment time long, and the modern cross-roll straightening machine that can't be used for having automation adjustment function.
Summary of the invention
Be the deficiency that solves the problems of the technologies described above, the utility model provides a kind of corner retaining mechanism, can effectively solve the problems of the technologies described above.
Be the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: the principle of utilizing inclined-plane reinforcement and self-locking, employing is at oil cylinder with between the plane that needs to lock, increase an oblique mechanism, the active force of oil cylinder is transformed into the pulling force of a rigid bar, promptly between oil cylinder and locking plane, an oblique mechanism wedge is set.Adopt an oil cylinder to promote moving of wedge, wedge spurs the lifting of connecting rod again, thereby between two planes of rotating, produce the frictional force of changeing big, thereby only need less cylinder thrust just can produce coupling mechanism force than the big several times of pulling force of an oil cylinder of direct use.Utilize the self-locking property and the small characteristics of push-and-pull rod distortion on inclined-plane simultaneously, guaranteed the reliability of corner plane locking effect.
The utility model has structurally also been taked the needs that are connected with existing oil cylinder retaining mechanism, just can guarantee this device to be installed on the machine of needs transformation only need carrying out less change on the existing equipment.
The utility model is under the performance that effectively guarantees the locking of cross-roll straightening machine aligning corner, not only can reduce the quantity of the higher oil cylinder of price for the straightener with roll gap fast rise and press function and large-scale straightener with automatic control function, can guarantee simultaneously flattening precision and leveling effect to steel pipe, the main surface quality grade that is so has improved product percent of pass and tubing, the indirect economic effect that is produced is very considerable.
Description of drawings
Fig. 1 is a generalized section of the present utility model
Mark among the figure: 1, locking cylinder, 2, the locking pull bar, 3, wedge, 4, the fixed connection plate, 5, the plane A that is locked, 6, plane B is locked.
The specific embodiment
As shown in Figure 1, locking cylinder (1), locking pull bar (2), wedge (3) is installed on the fixed connection plate (4), be installed on the plane A (5) that is locked by fixed connection plate (4), one end of locking pull bar (2) and wedge (3) constitute the inclined-plane force-increasing mechanism, and the other end adopts a ring surface to connect and compose stressed closed-loop with the plane B (6) that is locked.
When the piston of locking cylinder (1) stretches out, promote the action of wedge (3), wedge will be locked upwards lifting of pull bar (2) under the effect on inclined-plane simultaneously, thereby in the plane A (5) that is locked and the bigger thrust of generation between the plane B (6) that is locked, this thrust forms frictional force (or moment of friction) simultaneously between two planes, stop to produce between the plane of constraint to relatively move and rotate, and will have smoothing roll corner locking in relative rotation.
Claims (3)
1, a kind of cross-roll straightening machine corner plane retaining mechanism, be provided with locking cylinder (1), locking pull bar (2), wedge (3) and fixed connection plate (4), it is characterized in that: between locking cylinder (1) and locking plane (5), an oblique mechanism wedge (3) is set.
2, a kind of cross-roll straightening machine corner according to claim 1 plane retaining mechanism, it is characterized in that: locking cylinder (1), locking pull bar (2) are installed on the fixed connection plate (4) with wedge (3), are installed on the plane A (5) that is locked by fixed connection plate (4).
3, a kind of cross-roll straightening machine corner according to claim 1 plane retaining mechanism is characterized in that: an end of locking pull bar (2) is connected with wedge (3), and the other end is connected with the ring surface of plane B (6) employing that is locked.
