Description
Technical Field
The utility model relates to a roll-type leveler equipment technical field especially relates to pull rod screwdown formula leveler.
Background
In the existing roller leveler, leveling rollers and roller systems of a supporting mechanism (including a middle roller) are respectively arranged on a movable upper beam and a fixed lower beam, stand columns are respectively arranged at four corners of two ends of the movable upper beam and the fixed lower beam, end beams are designed among the stand columns, and the four stand columns bear all leveling pressure. In order to make up for the lack of rigidity of the upright column, a large-scale roller leveler generally arranges a longitudinal connecting beam above the movable upper beam and between the beams at two ends, and then adds a stud connecting end beam and a fixed lower beam in the upright column to strengthen the rigidity. And a pressing power mechanism of the movable upper beam and the upper leveling roll system is arranged in the middle of the end beam. Usually, a worm gear drives a screw rod to lift, and the screw rod lifts to drive a movable upper beam to lift on the inner side of an upright post.
According to the roller type leveler with the structure, the worm and gear screw rod pressing power mechanism bears all leveling forces, the stress point of the pressing power mechanism is close to the center of the end beam, stable support is difficult to form on the whole upper beam when a material to be leveled enters and exits the leveler, and the change of gaps between an inlet and an outlet is obvious when the material enters and exits the leveling rollers, so that the leveling force of the roller type leveler is unbalanced and stable, and the leveling (leveling) effect is influenced.
Moreover, the movable upper beam is driven by the lifting of the screw rod, so that the leveling roller floats upwards axially after being pressed down, and the leveling effect of the leveling roller is influenced. In order to eliminate the gap between the screw mandrel and the nut, a spring is generally mounted on the end beam or the connecting beam. However, the spring is close to the middle of the movable beam, and the situation of unbalanced stress can be met, so that the gap eliminating effect is not ideal. And also restricts the leveling effect of the roller leveler.
Chinese patent 201410077882.1 discloses a tension rod pressing type leveler, which comprises a tension rod, a movable upper beam and a fixed lower beam, wherein the movable upper beam is provided with an upper leveling roller, the fixed lower beam is provided with a lower leveling roller, four corners of two ends of the movable upper beam are connected with the tension rod, the fixed lower beam is connected with a tension rod pressing power mechanism, the tension rod is arranged in a tension rod seat at two ends of the upper beam, a tension rod power device is arranged at the bottom of the fixed lower beam corresponding to the tension rod seat, the tension rod is arranged in the tension rod seat and connected with the power device, and the power device enables the tension rod to relatively displace with the tension rod seat in the axial direction; the pull rod pressing-down type leveler with the structure cancels the transverse end beam and the longitudinal cross beam, so that the structure of the leveler is simpler, and the acting point of the pressing power device is positioned on the outermost side of the movable upper beam, so that the balance of the leveling roller is easy to control.
However, in the use process of the leveling machine, because the leveling effect of the leveling machine is easily influenced by the gap between the pull rod and the worm gear, the elastic part can be arranged on the pull rod, when the leveling machine works, the pull rod moves downwards under the driving of the worm gear, the upper end of the elastic part moves downwards along with the pull rod, the elastic part is compressed, the restoring force of the elastic part pushes the pull rod upwards, and the elastic part pushes the pull rod upwards to enable the upper supporting surface of the thread of the pull rod to be tightly abutted to the internal thread of the worm gear before the upper leveling roller on the movable upper beam is not contacted with a plate to be leveled, so that the pull rod cannot move upwards any more during the subsequent leveling action, the thread gap between the pull rod and the worm gear is eliminated, and the purpose of enhancing the leveling effect of the upper leveling roller is realized. The existing elastic pieces are usually springs or other elastic pieces made of elastic materials and capable of being used in a reciprocating mode, and the elastic pieces are prone to insufficient recovery power, poor recovery and the like in the using process, so that thread gaps between the pull rod and the worm wheel cannot be completely eliminated, and the straightening effect of the straightening machine is influenced after the working time is long. Therefore, after the leveler is used for a period of time, fixed-point leveling needs to be carried out within a short period of time so as to achieve the purpose of eliminating the gap between the pull rod and the worm gear, and the quality of the leveled product of materials such as a rolling plate and the like can be influenced if the leveling is not carried out in time.
