Abstract

The utility model relates to an improved roller straightening machine, whose roller system comprises an upper row of rollers and a lower row of rollers. The difference is that each roller in the lower row is driven by a motor or an oil motor and the driving devices of contiguous rollers are respectively arranged the two sides of the rollers. Each roller of the utility model has a uniform torque, no mechanical interference, no vibration and no slippage phenomenon, which enhances straightening quality, improves producing efficiency and does good to straightening mode for medium plates to use unparallel roller rows.

Description

Sub-roll main driving roll type leveling machine

The utility model relates to a kind of improvement of gaugger.

Existing gaugger is that single main motor links to each other with each roller by transmission system, and its gearratio is identical, so each roller rotating speed is identical.In its course of work, owing to the size of the bent wrinkle of workpiece and the randomness that distributes or owing to roller is adjusted reasons such as improper, part smoothing roll and transmission system generation mechanical interference thereof often appear, overburden damages, phenomenons such as skid in roller and workpiece part, vibration.

Be listed as uneven gaugger for roller, the roller drafts difference of input and output material end, thereby each roller place workpiece deformation difference.Because roller always is in internal layer one side of workpiece bending, and part curvature is big more, the internal layer amount of contraction is big more, and this place's roller linear velocity is more little, so the discharge end roller is bigger than feed end roller linear velocity.Because this speed official post roller is subjected to moment of torsion inhomogeneous, run up to a certain degree phenomenons such as i.e. generation is skidded, vibration.Problem hereto, the employing safety that has limit is turned round device and is solved, but it can only be installed on the last output shaft, and moment of torsion is bigger, and can not eradicate this shortcoming.

The purpose of this utility model provides the gaugger that the suffered moment of torsion of a kind of each roller is even, do not have mechanical interference, elimination vibration, skidding.

The utility model is for being made of the gaugger of its roller system the two rows roller, difference is that each root lower roll is driven by a motor or oil motor, and the drive unit of adjacent roller is divided into the both sides of roller.

The utility model each roller of row is down driven by motor or oil motor respectively, overcome owing to the crooked inequality of workpiece makes inconsistent each roller that causes of roller rotating speed be subjected to the moment of torsion inequality, skid, phenomenon such as vibration, improved correction quality, help selecting for use roller to be listed as not parallel rectification mode, enhance productivity for cut deal.The drive unit of adjacent roller sets up its both sides separately, has solved the problem that can't install this drive unit because roll spacing is little.The roll neck of the roll neck of all rollers of the present utility model, particularly driven roll should adopt little rolling bearing of coefficient of friction or static pressure, filmatic bearing as far as possible.For making each motor power output more even, can select the bigger motor of revolutional slip for use.

Accompanying drawing is the utility model embodiment lower roll and drive unit schematic diagram thereof.

It among the figure situation for nine roll steel plate arbor presses.Roller 1 is driven by motor 2, and 3 is transmission device.The drive unit of adjacent roller is divided into the both sides of roller as seen from the figure.The reductor of 2 transmission devices of homonymy can be installed in the reducer shell.

Charging for convenience improves the workpiece bite condition, or in order to strengthen pulling force to workpiece, to reduce the lower roll driving power, can establish drive unit respectively at the last all or part of roller of arranging roller, and its power should be less than or equal to the lower roll driving power.The driving of last row's roller also can adopt single motor band safety limit to turn round the type of drive of device.The drive unit of last row's roller preferably is fixed on therewith lifting on the moved cross beam.

Claims

1, a kind ofly constitutes the gaugger of its roller system, it is characterized in that each root lower roll is driven by a motor or oil motor, and the drive unit of adjacent roller is divided into the both sides of roller by the two rows roller.

2, by the described gaugger of claim 1, it is characterized in that arranging all or part of independently drive unit that is provided with of roller, perhaps the drive unit of the row's of going up roller is that single motor band safety limit is turned round device.
