Abstract
The invention discloses a method for adjusting a gap of blades of a pair of crank flying shears and a device thereof. An upper set of eccentric adjustment mechanism and a lower set of eccentric adjustment mechanism are arranged on a stander of the crank flying shears, and are respectively connected with an upper knife rest and a lower knife rest, and the upper knife rest and the lower knife rest are respectively driven by the upper set of eccentric adjustment mechanism and the lower set of eccentric adjustment mechanism to move at the same direction or the reverse direction, so that the gap of the blades on the upper knife rest and the lower knife rest is reduced or enlarged, the time for adjusting the gap of the blades of the shears is effectively reduced, the method is convenient to operate, the precise adjustment is easily realized, and the production efficiency is improved.
Description
Technical field
The present invention relates to metallurgy industry and be used for the flying shear technical field that steel rolling production-line is sheared, especially relate to a kind of crank flying shear blade clearance adjustment method and device.
Background technology
In steel rolling production-line, the flying shear that is used for rolled piece is implemented to shear is one of key equipment of steel rolling production-line, flying shear be generally used for to rolled piece implement crop, back-end crop, to cut multiple length, segmentation and accident cataclasm, burr size when one of important indicator of finished product mill bar quality is exactly the flying shear shearing, this just requires the numerical value of the blade clearance of flying shear to want accurately.At present, the method of adjustment of plus-minus pad between scissors and knife rest is adopted in the adjustment of the blade clearance of crank flying shear mostly, the enforcement body of existing crank flying shear blade clearance adjustment method as shown in Figure 1, measure gap and registration between the upper and lower cutting edge, calculate the thickness of required increase or minimizing according to arts demand, then, the screw 3 of fixed blade 4 is backed out, after vertically pad 5 and horizontal pad 2 are added between knife rest and the scissors, again screw 3 is tightened.If it is improper to add the gap of measuring between the cutting edge behind the pad, also need again scissors to be taken off, repeat primary operation, operating procedure is many, and assembling-disassembling bolt quantity is many, wastes time and energy very much, influences output.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of crank flying shear blade clearance adjustment method and device, it can just can reach the purpose of adjusting cutting edge registration and blade clearance under the situation of not taking off scissors.
For achieving the above object, the present invention adopts following technical scheme:
A kind of crank flying shear blade clearance adjustment method, it is by installing on the frame of crank flying shearing machine, two overlap eccentric adjustments down, on, two cover eccentric adjustments are respectively with last down, lower slide connects, eccentric adjustment is by eccentric shaft, adjust wheel, fixed cover, big endplay device, little endplay device and bracing or strutting arrangement are formed, eccentric shaft is installed in the axis hole of frame and an end extends outside the frame, be arranged with fixed cover on the eccentric shaft, fixed cover extends the outer part of frame and is fixed on the frame by the fixed cover screw, eccentric shaft extends the outer end of frame and by key the adjustment wheel is installed, little endplay device one end is equipped with bracing or strutting arrangement, little endplay device is connected by the eccentric shaft in the axis hole of bracing or strutting arrangement and frame, the other end of little endplay device is connected with an end of big connecting rod mechanism by connecting axle, and the big connecting rod mechanism other end is connected with knife rest; Upper and lower eccentric adjustment drives respectively that upper and lower knife rest is done in opposite directions or the rightabout motion, makes the scissors blade clearance on the upper and lower knife rest reduce or increase.
Described crank flying shear blade clearance adjustment method, its bracing or strutting arrangement comprises bearing, saturating lid, short spacer, sealing ring and long spacer, the forward and backward port place that little endplay device is one section all is installed with lid, sealing ring is installed in the lid, short spacer all is installed between forward and backward lid and the eccentric shaft, the relative side of forward and backward lid all is equipped with bearing, between two bearings long spacer is installed.
Because adopt aforesaid technical scheme, the present invention has following superiority:
This blade clearance method of adjustment and device, it is simple in structure, modern design, can be under the situation that does not take down scissors, rely on to rotate adjust wheel, so drive the eccentric shaft motion mode, and utilize the kinetic characteristic of crank connecting link, realize simultaneously upper and lower scissors in the horizontal direction with the same moved further of vertical direction, make the gap of upper and lower scissors cutting edge increase or reduce, effectively reduced the time of adjusting the scissors blade clearance, be convenient to operation, realize easily accurately adjusting, improved production efficiency.
