Description
The utility model relates to a kind of planetary differential flying shear machine.
Flying shearing machine are a kind of machines that can shear steel in steel high speed traveling process.Along with the raising of type steel production line mill speed, higher requirement is proposed also flying shearing machine.Adopt the flying shearing machine of startup formula duty, start or braking acceleration, must select the low inertia direct current of big capacity or pneumatic clutch and brake for use for adapting to, these equipment price costlinesses, dependence on import, working service is strict, and the spare and accessory parts supply is difficult to guarantee in addition.With the raising of mill speed, also structural design and the cut-in without ball mechanism to the flying shearing machine main frame proposes higher requirement in addition.
The purpose of this utility model is to disclose a kind of flying shearing machine that can adapt to high speed shear.
Task of the present utility model is achieved in that a satellite differential is set between flying shearing machine main frame and direct current generator, this differential mechanism is a power shaft, two output shafts, its power shaft is connected with direct current generator, an output shaft is connected with the flying shearing machine main frame through shaft coupling, this shaft coupling is provided with dynamo-electric brake, and another output shaft is provided with another dynamo-electric brake.
After using technique scheme, two alternately brakings of brake, can under the situation of motor continuous running, make flying shearing machine realize startup formula duty, used brake only needs the common electric brake, do not need inlet gas dynamic clutch or pneumatic braking device, direct current generator also no longer need be selected low for use.Because the motor continuous running does not participate in startup one braking procedure, its capacity also can reduce in addition.Above characteristics descend the cost that is used for twin shaft rod-type flying shearing machine on the rolling of sectional iron line or planet flying shearing machine at present significantly, and cutting trimming speed increases, and except that as the shaped steel crop, also can carry out scale or double length shearing.
Below in conjunction with drawings and Examples the utility model is specified.
Fig. 1 is the utility model main structure schematic diagram.
Fig. 2 is the planet flying shearing machine sizing mechanism of reinforcing structural representation that is adopted.
Fig. 3 is a crank linkage driving system schematic diagram among Fig. 2.
Fig. 4 is planet flying shearing machine side views.
Fig. 5 is the cutaway view of Fig. 4.
Be provided with a differential mechanism 3 among Fig. 1 between motor 1 and the flying shearing machine main frame 5, motor 1 is connected with the power shaft 6 of flying shearing machine 3 through shaft coupling, its output shaft 7 is connected through the line shaft of shaft coupling 4 with flying shearing machine 5, be provided with a brake 8 on this shaft coupling 4, the axle head of another output shaft 9 of flying shearing machine 3 also is provided with another brake 2.Motor 1 is in the continuous running state during use, does not participate in to start or the braking alternate run.If make flying shearing machine 5 runnings, promptly be in the shearing work state, brake 8 is discharged brake 2 brakings, the planetary reduction gear of differential mechanism 3 a suitable single shaft 7 outputs this moment.If brake 2 is discharged, with brake 8 brakings, at this moment, differential mechanism 3 is in single shaft 9 idle running output states, flying shearing machine 5 stalls.Replace the moment of braking when two brakes 8,2 are in, differential mechanism 3 becomes the differential operating condition of two output movements of an input motion, and the existence of this differential motion state is very favourable for the impact of parts such as load that reduces brake and gear.In fact motor 1 owing to be not to start system but make work continuously, its calculation of capacity is mainly considered the startup or the braking dynamic load of flying shearing machine moving component, so the motor desired volume can descend significantly, specification requirement to brake equally also reduces, the meaning on the other hand of this technological improvement is to improve shear line speed, the flying shear equipment of prior art level is after this technological transformation, can break through the limit of its shear line speed significantly, as crop or the 12m scale and the above double length shearing of 12m of high speed type steel production line.
The differential mechanism 3 that is adopted in the present embodiment is the internal tooth differential mechanism, and its planet carrier axle is an output shaft 7, is connected with flying shearing machine 5, and its ring gear is connected with output shaft 9 after speedup is joined tooth.Except that selecting the internal tooth differential mechanism for use, also can select negative sign external tooth differential mechanism for use, positive sign external tooth differential mechanism or umbrella tooth differential mechanism etc.
Adaptive flying shearing machine main frame can be twin shaft rod-type flying shearing machine, or planet knife bar flying shearing machine.
Should not adopt during cutting to length below flying shearing machine are used for 12m and start the system working method and should adopt cut-in without ball to operate, Fig. 2 provides the planetary differential cut-in without ball mechanism for implementing example of planet knife bar flying shearing machine, the synchromesh gear 10 of planet knife bar flying shearing machine is paid 18 by travelling gear and is obtained power among the figure, a hollow shaft (being the planet carrier axle) 16 be provided with one with the gear 12 of mentioning that train 11 is connected.The output shaft of this train 11 drives bent axle 13, and drives the periodicity that sun wheel shaft 15 up and down does 0 °-90 °-0 ° through push and pull system and back and forth rotate, and its reciprocal rotation period depends on the speed ratio of train 11.If the axe movement circumference of flying shearing machine knife bar planetary gear is 3m, when the speed ratio of train 11 was 2,3 or 4, pairing cut lengths was 6m, 9m or 12m.For example the speed ratio of train 11 is 2, and then hollow shaft 16 2 weeks of rotation, bent axle 13 changeed for 1 weeks, and sun wheel shaft 15 is finished a reciprocal rotation of 0 °-90 °-0 °, makes planet carrier 2 weeks of 17 revolutions, and cutting knife 19 is sheared once, promptly carries out the 6m cutting to length.
Fig. 3 is the linkage schematic diagram between bent axle 13 and the sun wheel shaft.Bent axle 13 is connected with the crank 26 of following sun wheel shaft through connecting rod 21 and lever 25, is connected with crank 24 on the last sun wheel shaft through connecting rod 22 again, and making up and down, sun gear rotates synchronously.Connecting rod 21 is provided with the long positive and negative machine nut-screw mechanism 20 of adjusting lever.Also be provided with the long guiding mechanism 23 of bar on the connecting rod 22, this mechanism is used for adjusting the gap of cutting knife.
