Abstract
An upper shearing machine balancing device of a roll cutting type shearer belongs to the technical field of steel rolling equipment and is used for reducing impact force on bearings and prolonging service life of the bearings. The technical scheme includes that the upper shearing machine balancing device consists of a hydraulic cylinder, a hydraulic cylinder upper bearing base and a shaft sleeve thereof, a hydraulic lower bearing base and a shaft sleeve thereof and a hydraulic connecting pin shaft, the hydraulic cylinder upper bearing base and the shaft sleeve thereof are fixed on the upper portion of a transverse beam of the shearer, the hydraulic cylinder lower bearing base and the shaft sleeve thereof are fixed on the top portion of an upper shearing machine, a front-end connecting rod of the hydraulic cylinder is connected with the hydraulic cylinder lower bearing base and the shaft sleeve thereof via the hydraulic cylinder connecting pin shaft, and a hydraulic driving mechanism is connected with the hydraulic cylinder. The hydraulic cylinder upwards pulls the upper shearing machine under action of the hydraulic driving mechanism, and upward pull force of the hydraulic cylinder is always slightly larger than gravity of the upper shearing machine so as to eliminate a clearance between tops of bearings of an upper joint and a lower joint of the connecting rod, thereby reducing impact force on the bearings of the upper joint and the lower joint generated by relatively large shearing force when shearing steel plates, and then achieving the purpose of prolonging service life of ball bearings.
Description
Technical field
The utility model relates to a kind of roll-turning cutter of plate rolling, belongs to the steel rolling equipment technical field.
Background technology
To the steel plate limit of roll forming and to shear end to end be a procedure in the plate rolling production line, the bilateral rolling cut of many employings of cutting edge is cut, crop end and scale adopt rotary cutting length shear more, and what printed line crop end and scale were cut in wherein being usually used in is that the up cut rolling cut is cut.In the transmission mechanism that the up cut rolling cut is cut, the connecting rod upper and lower end that connects driving crank and last shearing machine all is a ball bearing, because each bearing all has the gap, the greater impact power that produces when shearing steel plate makes that connecting rod upper and lower end ball bearing is shorter service life, especially is contained in the more easy deformation damage of oscillating bearing on the shearing machine, life cycle is shorter, and change difficulty of this bearing outside (copper mortar), time-consuming, effort has directly influenced finishing of production task.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can reduce when shearing impulsive force to bearing, increase shearing machine bascule on the roll-turning cutter in service life of bearing.
The technical scheme that solves the problems of the technologies described above is:
Shearing machine bascule on a kind of roll-turning cutter, it is connected bearing pin and is formed by hydraulic cylinder, hydraulic cylinder top chock and axle sleeve, hydraulic cylinder step and axle sleeve, hydraulic cylinder, hydraulic cylinder top chock and axle sleeve are fixed on the top of cutter crossbeam, hydraulic cylinder body and preceding end link are passed down through crossbeam, hydraulic cylinder step and axle sleeve are fixed on the top of shearing machine, hydraulic cylinder connection bearing pin is connected the preceding end link of hydraulic cylinder with hydraulic cylinder step and axle sleeve, hydraulic drive mechanism is installed in outside the cutter, and hydraulic drive mechanism is connected with hydraulic cylinder.
Shearing machine bascule on the above-mentioned roll-turning cutter, described hydraulic cylinder, hydraulic cylinder top chock and axle sleeve, hydraulic cylinder step and axle sleeve, hydraulic cylinder connect bearing pin and are positioned on the central vertical axis of roll-turning cutter.
Adopt on this roll-turning cutter behind the shearing machine bascule, hydraulic cylinder is upwards being held shearing machine under the effect of hydraulic drive mechanism, the pulling force that makes progress of hydraulic cylinder is slightly larger than the gravity of shearing machine all the time, to eliminate gap, connecting rod upper and lower oscillating bearing top, thereby big shearing force is to the impulsive force that connecting rod upper and lower end ball bearing produces when reducing to shear steel plate, plays to prolong the ball bearing purpose in service life.The utlity model has simple and compact for structure, transmission is convenient and reliable, and small investment, instant effect reduce the advantage of fault, cost saving.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: column 1, bent axle 2, hydraulic cylinder 3, hydraulic cylinder top chock and axle sleeve 4, connecting rod 5, crossbeam 6, upper joint bearing block 7, upper joint bearing 8, hypozygal bearing gland 9, hypozygal bearing 10, hydraulic cylinder step and axle sleeve 11, hydraulic cylinder connect bearing pin 12, last shearing machine 13, upper scissor blade 14, lower scissor blade 15, following shearing machine 16.
The specific embodiment
Show among the figure that the utility model is connected bearing pin 12 and formed by hydraulic cylinder 3, hydraulic cylinder top chock and axle sleeve 4, hydraulic cylinder step and axle sleeve 11, hydraulic cylinder.
This device is installed between roll-turning cutter two columns 1 of up cut, hydraulic cylinder 3, hydraulic cylinder top chock and axle sleeve 4, hydraulic cylinder step and axle sleeve 11, hydraulic cylinder connect bearing pin 12 and are positioned on the central vertical axis of roll-turning cutter, will go up shearing machine 13 and link together with crossbeam 6.
Hydraulic cylinder top chock and axle sleeve 4 are fixed on the top of crossbeam 6, hydraulic cylinder 3 cylinder bodies and preceding end link are passed down through crossbeam 6, hydraulic cylinder step and axle sleeve 11 are fixed on the top of shearing machine 13, hydraulic cylinder connection bearing pin 12 is connected the preceding end link of hydraulic cylinder 3 with hydraulic cylinder step and axle sleeve 11, hydraulic drive mechanism is installed in outside the cutter, and hydraulic drive mechanism is connected with hydraulic cylinder 3.
This design has made full use of the useful space of cutter, the greater impact power that produces during to the shearing steel plate, has cushioning effect preferably, to solving since the greater impact power that produces when shearing steel plate make connecting rod upper joint bearing 8, hypozygal bearing 10 early deformations damage and have very strong specific aim.Hydraulic cylinder 3 produces power (not showing) with Hydraulic Station and passes to shearing machine 13 on this external figure of cutter, the pulling force of hydraulic cylinder 3 is slightly larger than the gravity of shearing machine 13 all the time, just last shearing machine 13 there is individual overbalance effect all the time, to eliminate the gap, top of connecting rod upper joint bearing 8, hypozygal bearing 10, thereby big shearing force is to the impulsive force that connecting rod upper joint bearing 8, hypozygal bearing 10 produce when eliminating the shearing steel plate, plays to prolong these ball bearings purpose in service life.
