Abstract
The invention discloses a planet-connecting rod driving device comprising a gear a, a gear b, a sun gear, a planet gear, a gear c, a device balancing weight, a planet gear balancing weight, a connecting rod and a roll box; the gear a is connected with a motor; the gear b and the gear a are meshed; the gear b and the sun gear are coaxial; the center of the planet gear is fixed on the sun gear, and the planet gear and the gear c are meshed; one end of the connecting rod is fixed on the planet gear, and the other end is connected with the moving roll box; the device balancing weight is fixed on the sun gear, and the planet gear balancing weight is fixed on the planet gear. Through the planet-connecting rod driving device provided by the invention, the control difficulty of a cold pilger mill is reduced, the rolling frequency is increased, and the stable and reliable running is realized.
Description
Technical field
The invention belongs to field of mechanical technique, be specially a kind of tubing high-speed cold mill group planet-driving rod drive.
Background technology
At present, the roller case of cold pilger mill is the structure of four roller systems, comprises two backing rolls 2 and two working rolls 3 with variable cross-section pass, as shown in Figure 1.In effective impulse stroke scope (among Fig. 1 between I-I and the II-II), along with frame when reciprocating, roll pass and plug 5 will force by the diameter of tube rolling base and wall thickness and produce distortion and form a complete distortion cone in the course of work.Be equipped with precision and the surperficial roughness of curved surface plug to guarantee the production tube physical dimension by the deformation rule design in the inside of cone.Like this, when rolling-mill housing is done continual reciprocating motion, just can finish rolling to pipe.(tube billet 4 external diameters are about 90mm) is example with 90 cold pilger mills, the rolling frequency of high-speed cold Pilger mill is that the reciprocal time of operation of rolling central roll case is not less than 120 times/minute, the roll-force of rolling direction that roll bears is 10 ~ 15t simultaneously, move back and forth to follow simultaneously under the big roll-force in high-frequency and work, the roller case drive system and the balance sysmte of milling train proposed higher requirement.
Current, the drive system of pipe mill roller case be direct current generator by the flat belt transmission, connect with the crank gear system through the pin-type load shaft coupling, and drive the work housing reciprocating operation by connecting rod.The reciprocating motion of unit needs motor restarting and rotating repeatedly, increased the control difficulty so undoubtedly, motor restarts the service life of also having reduced motor with rotating repeatedly simultaneously, increased use cost, need the regular hour between the rotating of more crucial is motor, this has limited rolling frequency.With 90 cold-rolling mills is example, and the rolling frequency of current homemade cold reduction of tubes machine is up to 80 times/minute, and the rolling frequency of cold reduction of tubes machine of external advanced level is up to 120 times/minute.
Summary of the invention
Goal of the invention: in order to solve the problems of the prior art, the invention provides a kind of can reduction equipment the control difficulty, the tubing high-speed cold mill group that improves rolling frequency is with planet-driving rod drive.
Technical scheme: to achieve these goals, planet-driving rod drive of the present invention, it comprises: gear a, gear b, sun gear, planetary gear, gear c, device balancing weight, planetary gear balancing weight, connecting rod and roller case.
The annexation of above-mentioned each parts is as follows:
Described gear a is connected with motor; Gear b is meshed with gear a; Gear b is coaxial with sun gear; The center fixation of planetary gear is on sun gear, and planetary gear is meshed with gear c; Connecting rod one end is fixed on the planetary gear, and the other end is connected with the roller case that moves; The device balancing weight is fixed on the sun gear, and the planetary gear balancing weight is fixed on the planetary gear.The effect of device balancing weight and planetary gear balancing weight is to guarantee the stable in the course of the work running at a high speed of planet-driving rod drive of the present invention.
Planet-driving rod drive of the present invention, the equal diameters of described sun gear and planetary gear.The diameter of described gear c is the twice of sun gear and planetary gear diameter.
Beneficial effect: planet-driving rod drive provided by the invention, compared with prior art has following advantage: by planet-driving rod drive of the present invention, reduced the control difficulty of cold pilger mill, improved rolling frequency, and it is reliable to operate steadily.

The specific embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims to the modification of the various equivalent form of values of the present invention and limit.
Embodiment
As the described a kind of planet-driving rod drive of Fig. 1-3, it comprises: gear a1, gear b2, sun gear 3, planetary gear 4, gear c5, device balancing weight 6, planetary gear balancing weight 7, connecting rod 8 and roller case 9;
Described gear a1 is connected with motor; Gear b2 is meshed with gear a1; Gear b2 is coaxial with sun gear 3; The center fixation of planetary gear 4 is on sun gear 3, and planetary gear 4 is meshed with gear c5; Connecting rod 8 one ends are fixed on the planetary gear 4, and the other end is connected with the roller case 9 that moves; Device balancing weight 6 is fixed on the sun gear 3, and planetary gear balancing weight 7 is fixed on the planetary gear 4.The equal diameters of described sun gear 3 and planetary gear 4, the diameter of described gear c5 are the twices of sun gear 3 and planetary gear 4 diameters.
The described planet of present embodiment-driving rod drive work engineering is as follows:
In the work, the rotating band moving gear a1 of motor rotates, and gear a1 driven gear b2 and sun gear 3 rotate; Planetary gear 4 around sun gear 3 revolution, is subjected to the effect rotation of gear c5 with the A point simultaneously, so planetary gear 4 is planetary motion in the course of the work, and the direction of its rotation and revolution is opposite, and revolution speed is half of rotational velocity; Because the B point that links to each other with connecting rod on the compensation sun gear of rotation for revolution is on the horizontal center line move reciprocatingly (diameter that reciprocating distance is gear c5) all the time, moves reciprocatingly thereby drive whole roller case.
