Description
Technical field:
The utility model relates to plate belt hot rolling shearing equipment technical field, particularly relates to the blade clearance guiding mechanism of plate belt hot rolling swing type cutter.
Background technology:
In plate belt hot rolling shearing equipment technical field, the blade clearance guiding mechanism is the important mechanism in the cutter, at dissimilar cutting mechanisms, corresponding blade clearance guiding mechanism is arranged.For cutting mechanism straight up and down, following several blade clearances method of adjustment is arranged usually: 1. adjust upper scissor blade, this structural adjustment is cumbersome, only be applicable to the open top roll housing down cut formula adjustment upper scissor blade of often not adjusting, mainly by fixed frame, adjust bolt, compositions such as clamping screw and moving beam; 2. adjustment lower scissor blade, this structural adjustment is not too convenient, only is applicable to that various the stopping that does not need often to adjust cut, and mainly is made up of lower scissor blade frame, clamping screw, sill and adjustment bolt etc.; 3. eccentric bushing (axle) formula, complex structure is adjusted more conveniently, is applicable to that swing type stops cutting and flying shear, mainly is made up of pendulum cutting edge frame, eccentric bushing and axle etc. 4. cam-type, easy to operate, gap length is very directly perceived, but structure more complicated, be applicable to that various stopping cut, mainly form by lock sleeve, locking wheel, fork wheel, handwheel, flower fork wheel, frame, sectional wheel, gear, bearing, axle, upper scissor blade frame, adjustment taper liner, cam, upper scissor blade and spring etc.More than several blade clearances method of adjustment characteristics are respectively arranged, it is applicable to mainly that straight up and down formula shears.But, the present blade clearance guiding mechanism that also is not applicable to the swing type cutter.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, easy to adjust, quick, the production efficiency height, and be applicable to the swing type cutter blade clearance guiding mechanism of different-thickness steel plate shearing in the hot rolling line.
The scheme that its technical problem that solves the utility model adopts is: a kind of swing type cutter blade clearance guiding mechanism is provided, comprises interconnective lower slide, base, swing arm, upper scissor blade, lower scissor blade, it is characterized in that: lower scissor blade is installed on the lower slide; Upper scissor blade is installed in the swing arm by Driven by Hydraulic Cylinder; Lower slide is connected with base by two bearing pins at two ends; Lining is installed between the installing hole on the bearing pin outside and the base; Bearing pin is fixed by axle head baffle plate and lower slide; At the two ends of lower slide and base junction a connecting rod is installed respectively, the two ends of each connecting rod are threaded, fixedly connected with lower slide in the hole that the one end passes on the base, its other end is equipped with the butterfly spring and adjusts nut, block is contained in the two ends of butterfly spring, and lock washer is placed in the gap between lower slide and the base; Its feature is that also the adjustment nut on two lateral connector bars has two respectively.
The beneficial effects of the utility model are: the blade clearance guiding mechanism is simple in structure, easy to adjust, has shortened the adjustment time of cutter blade clearance, has improved production efficiency.
