The blade gap adjusting mechanism is characterized in that the shafts of the pair of lower fulcrum rollers are fixed, and the pair of upper fulcrum rollers is respectively arranged on eccentric wheel parts of eccentric shafts positioned on the outer sides of the upper fulcrum rollers; the eccentric shafts are installed into fulcrum fixed sleeves through fixed bearings and are fixedly arranged on a vertical plate of a rack; two-side eccentric shafts are rigidly connected with a synchronizing shaft through positioning pins together to ensure the synchronous movement of the two-side eccentric shafts; and the outer end part of one-side eccentric shaft is provided with a driving shaft connected with a manual or electric adjusting mechanism. The blade gap adjusting mechanism is convenient to adjust and has high adjusting accuracy.
Description
The (1) technical field: the utility model relates to a kind of gap blade guiding mechanism of hydraulic gate type guillotine shear.
The (2) background technology: for adapting to the requirement of shearing the different-thickness plate, plate shearing machine need be regulated the size of gap blade according to thickness of slab.Gap blade is crossed affects shear quality, makes the shear notching edge produce burr, too small can the wearing and tearing even the damage blade.Therefore plate shearing machine gap blade guiding mechanism requires reliable, easy to operate.
Traditional hydraulic gate type guillotine shear gap blade governor motion, the most commonly used with three fulcrums, promptly tool-post structure rotates it by three roller adjustment, thus the gap between adjustment cutter and the bottom knife.Be provided with upper roller and bottom roller at the back at tool-post structure, the tool-post structure front is provided with the front wheel of spring, and the spring of front wheel can make tool-post structure be close on the bottom roller after the precompressed.The axle of upper roller is fixed, and left and right sides bottom roller is assembled on the eccentric shaft of the left and right sides.Because of the tool-post structure rear side has back stock stop, can be in knife rest moves up and down process along with knife rest moves up and down together.As being installed between the lower fulcrum roller, the connection synchronizing shaft can interfere with it.So this type of gap blade guiding mechanism is adjusted with two cover controlling organizations respectively about being.Therefore possibly there is the inconsistent situation of left and right sides gap blade in gap blade, influences the plate shearing quality.
The (3) summary of the invention: the purpose of the utility model is that existing guiding mechanism is improved, and a kind of gap blade guiding mechanism of easy to operate, the high hydraulic gate type guillotine shear of adjustment precision is provided.
The gap blade guiding mechanism of a kind of hydraulic gate type guillotine shear of the utility model comprises upper slitter support body and lower slide body, and the back of upper slitter support body is provided with a pair of fulcrum roller of going up and reaches upward fulcrum guide rail plate, a pair of lower fulcrum roller and lower fulcrum guide rail plate; Upper slitter support body front is provided with the front fulcrum roller and the front fulcrum guide rail plate of a pair of band spring, and the lower end of upper slitter support body is fixed with cutter, and the upper end of lower slide body is fixed with bottom knife; Its improvements are: the axle of described a pair of lower fulcrum roller is fixed; And a pair of upward fulcrum roller is contained in respectively on the eccentric wheel part of a pair of eccentric shaft, and eccentric shaft is installed in the fulcrum fixed cover through rigid bearing again, and is fixed on the frame riser; The both sides eccentric shaft all is rigidly connected to guarantee that the both sides eccentric shaft is synchronized with the movement through alignment pin and synchronizing shaft; One lateral deviation axle outer end is provided with the power transmission shaft that is connected with manual or electronic guiding mechanism.
The course of work of the utility model is: when plate shearing machine need be adjusted gap blade, at first manual or electronic adjustment mode was rotated the power transmission shaft of an end eccentric shaft, and the both sides eccentric shaft rotatablely moves synchronously.The a pair of fulcrum roller of going up that is installed on the eccentric wheel part is moved forward and backward.Because front fulcrum roller band spring has certain precompressed amount, can float.Making the upper slitter support body is that rotate in the center of circle around rami posterior inferior point roller.Can adjust the position of upper slitter support body like this, thereby reach the purpose in gap between adjustment cutter and the bottom knife.
The described lock formula of the utility model plate shearing machine gap blade guiding mechanism; Different with prior art with the lower fulcrum roller adjustment of bikini rolling wheel guide rails structure; It is that last fulcrum roller adjustment with bikini rolling wheel guide rails structure is rotated it, thus the gap between adjustment cutter and the bottom knife.The lower fulcrum roller shaft of tool-post structure rear side setting is fixed, and last fulcrum roller is to be assembled in the eccentric shaft mechanism.The eccentric part offset of eccentric shaft is adjustable.During the adjustment gap blade, drive eccentric shaft through guiding mechanism and rotate, making the following fulcrum roller of upper slitter support body is that rotate in the center of circle, thereby the gap between the bottom knife is gone up in adjustment.
Because last fulcrum eccentric shaft rotational angle is easy to control, and the amount of movement of rotational angle and upper tool post has corresponding relation accurately, thereby eccentric rotation axis can make between upper and lower blade and produces microdisplacement.Has very high gap blade adjustment precision.And because left avertence axle left end can be installed on manual adjustment mechanism or reduction box transmission turbo-side; Eccentric shaft is by locked under the inactive state; Being knife rest, eccentric shaft can be because of shearing moment squint when shearing, and gap blade remains unchanged, and has guaranteed the stable of gap blade.
The utility model is easy to operate, the adjustment precision is high.
