Abstract
The utility model discloses an eccentric type cold flying cutter of a crank, which mainly consists of an upper cutter bar (1), a lower cutter bar, a drive system, a stander (3) and two movable fly wheels devices (4). The drive system comprises an upper cutting edge shaft, a lower cutting edge shaft and an electrical machine (5), the upper cutting edge shaft and the lower cutting edge shaft are respectively provided with a large gear, the large gear (7) of the lower cutting edge shaft is driven by two gear shafts (8), the two gear shafts (8) are respectively connected with the electrical machine (5), and each gear shaft (8) is provided with one movable fly wheels device (4). The two movable fly wheels devices (4) can be arranged not only between the stander (3) and the electrical machine (5), but also in the stander (3). The fly wheels are turned on when the cutter runs at a low speed, and the fly wheels are turned off when the cutter runs at a high speed, so that the eccentric type cold flying cutter of the crank can meet the technological requirement, can greatly reduce the power of the electrical machine and obtain higher economic benefit.
Description
Technical field
The utility model relates to a kind of flying shear equipment that steel rolling production-line carries out cutting to length that is used for, and relates in particular to a kind of cold flying shear of crank centering type with flywheel alive.
Background technology
In the steel rolling production technology,, need carry out cutting to length through cooled bar.In order to increase economic efficiency, now developed and the mode that the cold flying shear of a kind of usefulness carries out cutting to length, replaced the past to add the mode of fixedly cutting with shear gauge, this cold flying shear is mainly by knife bar, transmission system, frame etc. are formed up and down.
In general, big shearing force correspondence low shear rate, and the power of motor that needs is also bigger, and the shearing force that needs when high speed shear is much smaller, therefore just seem that power is excessive at the motor of selecting under the big shearing force operating mode of low speed during in the little shearing force operating mode of high speed, very unreasonable.In order to pursue higher economic benefit, require this cold flying shear to have bigger shear ability, bigger velocity variations scope and more accurate control accuracy.
The utility model content
The purpose of this utility model is to be to overcome the shortcoming that exists in the prior art, provides the crank centering type that a kind of velocity variations scope is big, control accuracy is high and power of motor is low cold flying shear.
For realizing described purpose, the cold flying shear of crank centering type of the present utility model comprises knife bar, following knife bar, transmission system and frame.Wherein transmission system comprises lower scissor blade axle and motor, last lower scissor blade axle respectively has a gear wheel, the gear wheel of lower scissor blade axle is by the through-drive of two rooted teeth wheel, and two rooted tooth wheel shafts link to each other with motor respectively, and its structural feature is: be provided with a flywheel gear alive on every rooted tooth wheel shaft.
The flywheel gear of living mainly comprises with the external toothing one of the flywheel one of living, is fixed on external toothing two and a ring gear that is enclosed within on the external toothing one on the gear shaft, is provided with a shift fork on ring gear.
Above-mentioned flywheel gear alive can be located on the gear shaft between frame and the motor, also can be located on the gear shaft in the frame.
Compared with prior art, the cold flying shear of the utility model crank centering type has the following advantages:
1, because the utility model has been set up flywheel gear alive, the flywheel alive that closes when shearing the low speed bar can strengthen shearing strength, helps motor to shear smoothly; Throw off flywheel when shearing the high speed bar, can reduce inertia, make motor finish the suitable braking that rises, so the cold flying shear of the utility model crank centering type has bigger shear ability, and the velocity variations scope is big, control accuracy is high.
2, because the utility model has disposed a suitable flywheel alive, the flywheel alive that closes during low velocity shear is thrown off the flywheel of living during high speed shear, just can reduce power of motor greatly when satisfying technological requirement, obtains higher economic benefit.
Description of drawings
Below in conjunction with the drawings and specific embodiments utility model is described in further detail.
Fig. 1 is the cold flying shear front view of the utility model crank centering type;
Fig. 2 is the vertical view of cold flying shear shown in Figure 1;
Fig. 3 is the cutaway view of Fig. 2 along the A-A direction;
Fig. 4 is the cutaway view of Fig. 3 along the B-B direction.
The specific embodiment
From Fig. 1 and Fig. 2 as can be known, the cold flying shear of crank centering type of the present utility model is mainly by last knife bar 1, knife bar 2, transmission system, frame 3 and two flywheel gears 4 alive are formed down.Wherein transmission system comprises lower scissor blade axle and motor 5, and last lower scissor blade axle respectively has a gear wheel, and the gear wheel 7 of lower scissor blade axle 6 is by 8 transmissions of two rooted tooth wheel shafts, and two rooted tooth wheel shafts 8 link to each other with motor 5 respectively, and a flywheel gear 4 alive is housed on every rooted tooth wheel shaft 8.The flywheel gear 4 of living both can be located between frame 3 and the motor 5, also can be located in the frame 3, and the flywheel gear 4 of living in the present embodiment is on the gear shaft 8 between frame 3 and the motor 5.
From Fig. 3 and Fig. 4 as can be known, the flywheel gear 4 of living mainly comprises with the external toothing 1 of the flywheel one of living, is fixed on external toothing 2 42 and a ring gear 43 that is enclosed within on the external toothing 1 on the gear shaft 8, is provided with a shift fork 44 on ring gear 43.
One of them flywheel gear 4 side of living is provided with a brake disc 9, and brake disc 9 is being equipped with a pneumatic tongs disk brake 10, and this external toothing 2 42 of living flywheel gear 4 is fixedlyed connected with brake disc 9.
State when flywheel was thrown off when Fig. 3 was high speed shear.This moment, ring gear 43 only was meshed with the external toothing 1 of the flywheel one of living together, and threw off with the external toothing 2 42 that is fixed on the gear shaft 8.When 8 rotations of motor 5 driven gear axles, the flywheel alive that is separated by two rolling bearings 11 and gear shaft 8 can and then not rotate.
As can be seen from Figure 4, when low velocity shear, extract shift fork 44 medi-spring latches 45, turning handle 46 makes shift fork 44 stir ring gear 43 and arrives the position that a while is meshed with external toothing 1 and external toothing 2 42.Inject night bolt 45, ring gear 43 can not be moved axially.When 8 rotations of motor 5 driven gear axles, the just rotation together of flywheel of living plays a role.
Because the utility model has disposed a suitable flywheel alive, the flywheel alive that closes during low velocity shear is thrown off the flywheel of living during high speed shear, just can reduce power of motor greatly when satisfying technological requirement, can obtain higher economic benefit.
