Abstract
The utility model relates to a pinch roller device on a hydraulic straightening machine, which comprises a pinch roller shaft, a pinch roller and a guide sleeve, wherein the pinch roller is fixedly sheathed at the front end of the pinch roller shaft by keys; the front end part of the pinch roller shaft is fixedly provided with a gland; the tail end of the pinch roller shaft is arranged in the guide sleeve; the pinch roller shaft in the guide sleeve is sheathed with two bearings and the pinch roller shaft between the two bearings is sheathed with an inner spacing bush; the outer part of the inner spacing bush is sheathed with an outer spacing bush; a clearance is left between the inner spacing bush and the outer spacing bush; the tail end part of the pinch roller shaft is fixedly provided with an end cover; the front end part of the guide sleeve is fixedly provided with a sealing cover; and the sealing cover is matched with the end cover to compact the two bearings axially. The pinch roller device is simple, compact and reasonable in structure; H-shaped steel workpieces with different web heights can be straightened, without the replacement of the pinch roller; and when the pinch roller is worn, as long as the gland is dismantled, the worn pinch roller can be replaced, and the operation is very convenient.
Description
Technical field
The utility model relates to a kind of hydraulic pressure arbor press upper pressure wheel device, belongs to mechanical equipment technical field.
Background technology
The hydraulic pressure arbor press is used for H shaped steel welding relief angle straightening H shaped steel wing plates on two sides and uses.In prior art, hydraulic pressure straightener pressing wheel external diameter is bigger, in bearing is arranged, can not satisfy the less workpiece of H shaped steel web height, only can correct big workpiece and bearing and damage easily, when correcting the less workpiece of H shaped steel web height, need to change little pinch roller, very trouble.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, providing a kind of hour all can correct when the thicker or H shaped steel web height of H shaped steel wing plate, need not change pinch roller, when the pinch roller wearing and tearing need to change, only need gland is pulled down, change the pinch roller hydraulic pressure arbor press upper pressure wheel device that operation is very easy.
The technical scheme that provides according to the utility model, described hydraulic pressure arbor press upper pressure wheel device, comprise wheel pressing shaft, pinch roller and fairlead, pinch roller is fixedly set in the front end of wheel pressing shaft by key, leading section at wheel pressing shaft is installed with gland, the tail end of wheel pressing shaft is installed in the fairlead, be on the wheel pressing shaft in the fairlead and be socketed with two bearings, be socketed with inner spacing collar on the wheel pressing shaft between two bearings, the inner spacing collar outer cover is connected to outer separator, has the gap between inner spacing collar and the outer separator, is installed with end cap at the tail end of wheel pressing shaft, leading section at fairlead is installed with seal cover, and seal cover cooperates with end cap two bearing axial compression.
Described bearing is a taper roll bearing, and the inner ring body length of bearing is greater than the length of its outer ring body.The thickness of described inner spacing collar is greater than the thickness of outer separator, and the length of inner spacing collar is less than the length of outer separator.The cylindrical of described inner spacing collar is concordant with the inner ring body cylindrical of bearing.
The utility model is simple, compact and reasonable for structure; Workpiece to the different web heights of H shaped steel can both be corrected, and need not change pinch roller, only need pull down gland and just can change pinch roller when pinch roller weares and teares, and operation is very easy.
