Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
A kind of magnesium alloy round billet continuous casting cutting on line machine, comprise bracket system, whirligig and cutter sweep, bracket system is connected to above whirligig, is connected with cutter sweep below whirligig.
With reference to Fig. 1, described bracket system comprises bracket 1, upper hold-fast body 2 and lower hold-fast body 3, hold-fast body 2 is connected with above bracket 1, lower hold-fast body 3 is connected with below bracket 1, when starting to cut, upper hold-fast body 2, lower hold-fast body 3 hold round strand tightly, make whole bracket system and circle strand geo-stationary, for cutting provides benchmark stress point; A1, a2, a3, a4 tetra-groups of pulleys that bracket 1 is striden across above it by steel wire rope are connected with counterweight, the weight sum of counterweight is greater than the gross weight of its pulling mechanism, before starting cutting, compression hydraulic cylinder on upper hold-fast body 2 and lower hold-fast body 3 is unclamped, and it is to be cut that rising above being risen to by cutting machine under the effect of counterweight cuts position etc.; After cutting machine receives cutting instruction, compression hydraulic cylinder orders about hold-fast body 2 and lower hold-fast body 3 holds strand tightly, and strand is static relatively to make bracket 1, is convenient to cutting synchronous with moving down of circle strand, for cutting provides basic fixed position condition and benchmark stress point.
See figures.1.and.2, described whirligig comprises rotary drive mechanism 4, pinion 5, gear wheel 6 and rotary frame 7, gear wheel 6 is fixedly connected with bracket 1, rotary frame 7 can rotate around bracket 1 central shaft, rotary drive mechanism 4 is connected to form by the first variable-frequency motor and the first reductor, first variable-frequency motor, first reductor is fixed on rotary frame 7, first speed reducer output shaft is connected with pinion 5, pinion 5 and gear wheel 6 engage, when the first variable-frequency motor order about pinion 5 rotate time, because the relatively round strand of gear wheel 6 is static, rotate around circle strand axis with regard to driven rotary frame 7, realize the function of rotation limit, cutter sweep limit cutting strand.
See figures.1.and.2, described cutter sweep comprises hydraulic cylinder 8, cutting frame 9, cutting driving mechanism 10 and cutting saw disc 11, piston rod head and the rotary frame 7 of hydraulic cylinder 8 are hinged, the middle part pin-and-hole of plunger shaft and cutting frame 9 is hinged, cutting frame 9 end pin-and-hole and rotary frame 7 hinged, cutting driving mechanism 10 is fixed on cutting frame 9 other end, cutting driving mechanism 10 is connected to form by the second variable-frequency motor and the second reductor, the output shaft of the second reductor is provided with cutting saw disc 11, according to cutting needs, by the change of the second variable-frequency motor rotating speed, realize the adjustment of cutting saw disc 11 rotating speed.
The inside of described hydraulic cylinder 8 is provided with displacement transducer, is regulated the anglec of rotation of rotary frame 7 by the telescopic location of hydraulic control cylinder 11, cuts the function needs of circle strand depth adjustment with satisfied cutting saw disc 11.
Operation principle of the present invention:
Before cutting, hold-fast body is in open mode, on bracket 1 be suspended on a1, a2, a3, a4 counterweight effect everywhere under, make cutting mechanics main part rest on cutting initial bit.
Strand leaves the length of cutting starting point when reaching requirement, and hold-fast body instruction holds strand tightly immediately, and whole cutting main body machinery and strand are synchronously moved down.
Second variable-frequency motor of cutting driving mechanism 10 starts to rotate, and after giving the second reductor, drives cutting saw disc 11 to rotate according to cut direction by power transmission.The piston rod retraction of hydraulic cylinder 8, makes cutting saw disc 11 by instruction incision strand certain depth.
First variable-frequency motor of rotary drive mechanism 4 starts to rotate according to instruction, by power transmission to the first reductor, driving pinion 5 rotates again, under the driving force effect that pinion 5 is meshed with gear wheel 6, rotary frame 7 drives saw disc 11 to rotate around strand, complete the ring cutting function to strand, through the ring cutting of multi-pass, strand is completely severed.
Second variable-frequency motor stops the rotation, and the piston rod of hydraulic cylinder 8 extends, and pushes saw disc 11 open, and the first variable-frequency motor reversely rotates, and orders about whole cutting mechanics body and gets back to initial position.Hold-fast body 2 is opened, and moves, and rest on cutting initial bit under a1, a2, a3, a4 counterweight effect everywhere that is suspended on bracket 1.Wait instruction carries out next cutting instruction.
