Abstract
The utility model relates to a compression roller device of a hydraulic straightening machine, comprising an axle box and a compression roller axle, wherein the compression roller axle can be supported in the axle box in a rotating way, and the front end of the compression roller axle extends out of the axle box and is detachably connected with the small compression roller device, and a compression roller axle positioning device is arranged between rear end of the compression roller axle and the axle box. In the utility model, through the arrangement of the small compression roller device on the existing hydraulic straightening machine, the hydraulic straightening machine which can only straighten heavy H-shaped steel can straighten light H-shaped steel, the applicable scope of the hydraulic straightening machine is enlarged, and the purchasing cost of a user is saved.
Description
Technical field
The utility model relates to the hydraulic pressure arbor press of correcting H shaped steel, specifically a kind ofly promptly can correct the press-roller device that heavy H-steel can be corrected the hydraulic pressure arbor press of light-duty H shaped steel again.
Background technology
Along with expanding economy, steel building is by increasing employing, and modern plant equipment is also adopted in the making of steel construction piece more and more.H shaped steel is the most frequently used steel construction piece of steel building, and its making mainly partly is made up of assembly unit, welding, rectification etc.The hydraulic pressure arbor press is mainly used in the welding deformation of correcting H shaped steel wing plate.H shaped steel is the most frequently used steel construction piece of steel building, and its making mainly partly is made up of assembly unit, welding, rectification etc.H shaped steel has heavy and light-duty branch, and correspondingly arbor press also is divided into heavy H-steel arbor press and light-duty H shaped steel arbor press.
Thickness mainly adopts the hydraulic pressure arbor press greater than the rectification of 40 millimeters heavy H-steel wing plate at present, and the wing plate thickness that can correct H shaped steel can reach 80 millimeters.Its rectification mode is: correct the upwards centre of roof pressure H shaped steel wing plate of wheel down for 1, go up for 2 and correct the both sides that wheel is pushed down wing plate, the both sides of wing plate are corrected to the rightabout of welding deformation.Though this hydraulic pressure arbor press can be corrected heavy H-steel,, can't carry out corrective operations for the H shaped steel of small dimension because that it corrects wheel construction size is bigger.For the user, often be heavy, light-duty H shaped steel alternately operating, have to buy two kinds of arbor presses for this reason and satisfy the production demand, increased user's acquisition cost.
Summary of the invention
The utility model provides a kind of press-roller device of hydraulic pressure arbor press to the problems referred to above, is equipped with the hydraulic pressure arbor press of this press-roller device promptly can correct heavy H-steel and can corrects light-duty H shaped steel again, and is applied widely.
Technical scheme according to the utility model: a kind of press-roller device of hydraulic pressure arbor press, comprise axle box and pressure roller shaft, said pressure roller shaft is rotatably supported in the said axle box, and the front end of said pressure roller shaft stretches out said axle box; The front end of said pressure roller shaft removably is connected with the air bells removing roll device, is provided with the pressure roller shaft positioner between the rear end of said pressure roller shaft and the said axle box.
Said air bells removing roll device comprises little axle and is installed in rotation on the air bells removing roll on the said little axle, and said little axle is fixed on the connecting plate, and said connecting plate is through being bolted to the front end end of said pressure roller shaft.
Said little eccentric shaft is installed in the front end end of said pressure roller shaft.
Be with axle sleeve on the front end circumference of said pressure roller shaft.
Said pressure roller shaft positioner comprises the antirotation keys that is fixed on end, said pressure roller shaft rear end, and the two ends of said antirotation keys are embedded in the keyway of offering said axle box rear end.
The technique effect of the utility model is: the utility model is through air bells removing roll device on changing the outfit on the existing hydraulic pressure arbor press press-roller device; Make the rectifiable light-duty H shaped steel of the hydraulic pressure arbor press that to correct heavy H-steel; Increase the scope of application of hydraulic pressure arbor press, saved user's acquisition cost.
Description of drawings
Fig. 1 is the structural representation of existing hydraulic pressure arbor press.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1, Fig. 2, comprise large pressuring roller 1, air bells removing roll 2, axle box 3, pressure roller shaft 4, antirotation keys 5, bearing 6, connecting plate 7, little axle 8, axle sleeve 9 etc.
As shown in Figure 1, be the press-roller device of existing hydraulic pressure arbor press, comprise axle box 3 and pressure roller shaft 4, pressure roller shaft 4 is rotatably supported in the axle box 3, and the front end of pressure roller shaft 4 stretches out axle box 3 and through key large pressuring roller 1 is installed.
As shown in Figure 2, be the press-roller device of the utility model, be on the basis of existing press-roller device, to convert.During repacking, large pressuring roller 1 is pulled down, the front end in pressure roller shaft 4 removably is connected with the air bells removing roll device then, between the rear end of pressure roller shaft 4 and axle box 3, is provided with the pressure roller shaft positioner.
Above-mentioned air bells removing roll device comprises little axle 8 and is installed in rotation on the air bells removing roll 2 on the little axle 8 through bearing 6, and little axle 8 is fixed on the connecting plate 7, and connecting plate 7 is through being bolted to the front end end of pressure roller shaft 4.Air bells removing roll 2 is through little axle 8 rotations of bearing 6 around oneself, so can not follow pressure roller shaft 4 rotations.
The effect of above-mentioned pressure roller shaft positioner is in order to prevent that air bells removing roll 2 from rotating with pressure roller shaft 4.The pressure roller shaft positioner comprises the antirotation keys 5 that is fixed on end, pressure roller shaft 4 rear end, and the centre of antirotation keys 5 is embedded in the keyway of end, pressure roller shaft 4 rear end, and the two ends of antirotation keys 5 are embedded in the keyway of offering axle box 3 rear ends.
Because the radial dimension of air bells removing roll 2 is little more a lot of than large pressuring roller 1, can stretch in the middle of two blocks of wing plates of small dimension H shaped steel, so can correct the wing plate welding deformation of small dimension H shaped steel.When needs are corrected big specification H shaped steel, pull down air bells removing roll 2 and antirotation keys 5 again, reload large pressuring roller 1 and get final product.
Because the jacking cylinder stroke of hydraulic pressure arbor press is limited, so the axial line of air bells removing roll 2 will be on the lower side in the axial line of pressure roller shaft 4, little axle 8 off-centre of air bells removing roll 2 are installed in the front end end of pressure roller shaft 4.
In order to protect the exposed parts of pressure roller shaft 4, on pressure roller shaft 4 front end circumference, can also be with axle sleeve 9.
The utility model is through pulling down the large pressuring roller 1 of existing hydraulic pressure arbor press press-roller device; Change the outfit and go up the air bells removing roll device; Make the rectifiable light-duty H shaped steel of the hydraulic pressure arbor press that to correct heavy H-steel; Increase the scope of application of hydraulic pressure arbor press, saved user's acquisition cost, floor space and use cost.
