Abstract
The utility model provides a locking device for a roller shell and a roll shaft of a cantilever straightening machine. The locking device for the roller shell and the roll shaft of the cantilever straightening machine comprises a roll shaft, a roller shell, a round nut, a flower-shape nut and a flower-shape platen, wherein the roll shaft is arranged in the roller shell, a draw rod is arranged at the front end of the roll shaft, and a top sleeve, a hydraulic cylinder, a disk spring and the round nut are arranged on the draw rod in sequence from left to right. The top sleeve is fixedly connected with the front end of the roll shaft, the flower-shape platen is arranged on the outer surface of the top sleeve in a sleeved mode, and the flower-shape nut is arranged on the outer surface of the hydraulic cylinder in a sleeved mode. The locking device for the roller shell and the roll shaft for the cantilever straightening machine has the advantages that a bolt arranged between the roll shaft and the roller shell is removed, motive power is transmitted by great pressure on the end face of the draw rod generated by the disk spring through adoption of the hydraulic cylinder, easy damage to the roller shell and the toll shaft in the process of section steel straightening production is avoided, and service life of the roller shell and the roll shaft is prolonged. Locking between the roller shell and the roll shaft is achieved through the matching between the disk spring and the round nut and the hydraulic cylinder without operation of a wrench, and the locking and fastening and dismantling of the roller shell can be achieved just by rotating the flower-shape nut and flower-shape platen manually.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of cantilever straightener, especially relates to a kind of for the roller shell of cantilever straightener and the locking device of roll shaft.
Background technology
Beam straightening is essential production process during shaped steel is produced, and modern straightener adopts cantilever design more, so that operation and boosting productivity, as shown in Figure 1, the type of attachment of roller shell 1 and roll shaft 2, the directly convenience that operates of impact and the raising of productivity ratio.
The roller shell 1 of the cantilever straightener in existing technology with the locking device of roll shaft 2 is: roller shell 1 is connected to come transferring power with roll shaft 2 by key 11, and flower shape platen 5 compresses roller shell 1 by flower shape nut 7, and flower shape nut 7 compresses by round nut 10; When tearing roller shell 1 open, unclamp round nut 10 and flower shape nut 7, with flower shape platen 5 and flower shape nut 7 corresponding turn an angle after, when making roller shell 1 and flower shape nut 7 relative with the groove of spending shape platen 5, roller shell 1 can be extracted out vertically, owing on roller shell 1 and the roll shaft 2 keyway is arranged, the stress that produces is concentrated, cause beam straightening produce in roller shell 1 damage easily the lost of life with roll shaft 2, spend in addition shape nut 7 and round nut 10 lockings to need to use artificial wrench operated, the efficient that wastes time and energy is low.
Summary of the invention
Problem to be solved in the utility model provides a kind of for the roller shell of cantilever straightener and the locking device of roll shaft of a kind of simple in structure, long service life, convenient operation, high efficiency, especially is fit to high efficiencyly to finish the aligning of shaped steel.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of for the roller shell of cantilever straightener and the locking device of roll shaft, comprise roll shaft, roller shell, round nut, flower shape nut, flower shape platen, described roll shaft is located in the roller shell, the front end of described roll shaft is provided with pull bar, is arranged with successively from left to right top cover, hydraulic cylinder, dish spring, round nut on described pull bar; Described top cover is fixedly connected with the front end of described roll shaft, and described top cover outer surface is arranged with colored shape platen, and described hydraulic cylinder outer surface is arranged with colored shape nut.
In use, hydraulic cylinder is carried out punching press, piston in the hydraulic cylinder will have proal trend, because piston nose is provided with top cover, motion compresses dish spring produces pressure so the cylinder body of hydraulic cylinder is incited somebody to action backward, because dish spring right side is provided with round nut, so pressure one end of dish spring is passed to the hydraulic cylinder other end and is passed to round nut, manually can will spend the shape nut to tighten forward and compress colored shape platen easily this moment, and then compress roller shell, at this moment hydraulic cylinder pressure relief; When tearing roller shell open, hydraulic cylinder is carried out punching press, in like manner the cylinder body of hydraulic cylinder is incited somebody to action backward motion compresses dish spring, flower shape nut is namely driven backward by cylinder body manually can will spend the shape nut to unscrew behind the mobile segment distance easily, at this moment, hydraulic cylinder pressure relief is with flower shape nut and corresponding the turning an angle of flower shape platen, make its groove relative with described roller shell, roller shell is extracted out.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, key between cancellation roll shaft and the roller shell, adopt hydraulic cylinder to make the dish spring come transferring power at the large pressure of end face generation of pull bar, prevent that roller shell and roll shaft damage easily in the beam straightening production, strengthen the service life of roll shaft and roller shell; Utilize the cooperation of dish spring and round nut and hydraulic cylinder to reach the locking of roll shaft and roller shell, need not use artificial wrench operated, only need manually be rotated locking and dismounting that colored shape nut and flower shape platen can be realized roller shell; The advantage such as have simple in structure, easy operation, the life-span is long, operating efficiency is high.
