Abstract
The utility model relates to a crank connecting rod mechanism which is used for a periodic two tubes cold pilger mill which has two balance blocks, a motor input rotor shaft, a gear box, a driver gear, a crank gear, a connencting rod, a stander. The gear box connects two parallel placing driver gears, the crank gear and the connencting rod; a balance block is arranged on the driver gear and the crank gear. The line of the balance block and circle center of the gear has the same angle with the line of driving gear shaft, crank gear shaft and the connencting rod sliding line but converse direction. Two groups of driving gear rotate conversely with the crank gear. The utility model has the advantages that adopting two balance blocks adding a balance device that is two flat surface mechanism balance blocks that rotate conversely are used for adding the balance blocks to balance the inertia force generated when the connencting rod and crank mechanism running, and to diminish vibration so as to making the cold pilger mill running at a high speed.
Description
Technical field
The utility model relates to a kind of additional bascule, particularly a kind of two-tube cold pilger mill toggle of periodic with two balance weights.
Background technology
The impulse stroke of the two-tube cold pilger mill frame of present periodic is by connecting rod, and it is reciprocating that the rotatablely moving of crank finished.In high-speed motion, produce vibration by the inertia force in the reciprocal process of crank, connecting rod and frame.For reducing the impact of inertia force, adopt common technical measures to have in the existing cold-rolling pilger mill: (1) flywheel energy storage buffer unit, (2) crankwheel configuration bascule.(3), old HM type etc., the technical measures of flywheel energy storage buffer unit and crankwheel configuration bascule, the vibration that inertia force is produced in the time of can not eliminating the cold-rolling pilger mill operation fully, for this reason, machine generally can only be worked under less than 60 times/minute speed.And the balancing technique measure of its inertia force of old HM type system is better, but complete equipilibrium not also simultaneously, requires to dig a dell so that bascule to be installed.Therefore also not very good.
Summary of the invention
The purpose of this utility model is the vibrative problem of inertia force that solves in the reciprocal process of frame of the two-tube cold pilger mill of periodic in the prior art, provide a kind of and can eliminate vibration, reach run up two balance weights of the two-tube cold pilger mill of periodic of purpose of cold pilger mill.The utility model design has the two-tube cold pilger mill toggle of periodic of two balance weights, comprise motor input rotating shaft, gear-box, travelling gear, crank gear, connecting rod, frame, it is characterized in that: gear-box connects two groups of travelling gears, crank gear, the connecting rod of parallel placement, on travelling gear and crank gear, balance weight is arranged, balance weight center on travelling gear and the crank gear is consistent with the angle of the line of the line in the gear center of circle and travelling gear rotating shaft and crank gear rotating shaft and connecting rod line of slide, and direction is opposite.The direction of rotation of two groups of travelling gears and crank gear.The utility model has the advantages that and adopted two balance weights to add bascule, i.e. two cover inverse direction runnings, the plane mechanism balance weight adds bascule, the inertia force that is in operation in order to balanced connecting rod, crank mechanism, eliminate vibration, reach the purpose that cold pilger mill runs up.On the two-tube cold pilger mill of the formula same period, adopt the additional bascule of two balance weights.The work period of cold pilger mill time/minute is brought up to 100 times/minute from common＜60.Its oscillation phenomenon obviously reduces, and vibration noise is＜62 decibels, and similar machine vibration noise is＞90 decibels.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a described principle schematic of the present utility model,
Accompanying drawing 2 is a structural representation of the present utility model,
The specific embodiment
11 is travelling gear among Fig. 1, and 12 is crank gear, and 13 is connecting rod, and 14 is balance weight.Balance weight 14 centers on travelling gear 11 and the crank gear 12 are consistent with the angle of the line of the line in the gear center of circle and travelling gear 11 rotating shafts and crank gear 12 rotating shafts and connecting rod 13 lines of slide, and direction is opposite.
Comprise motor input rotating shaft 1, gear-box 2, travelling gear 3, crank gear 4, connecting rod 5, frame 6 among Fig. 2, it is characterized in that: gear-box 2 connects two groups of travelling gears 3, crank gear 4, the connecting rod 5 of parallel placement, on travelling gear 3 and crank gear 4, balance weight 7 is arranged, balance weight 7 centers on travelling gear 3 and the crank gear 4 are consistent with the angle of the line of the line in the gear center of circle and travelling gear 3 rotating shafts and crank gear 4 rotating shafts and connecting rod 5 lines of slide, and direction is opposite.The direction of rotation of two groups of travelling gears 3 and crank gear 4.Because adopted two balance weights to add bascule, i.e. two cover inverse direction runnings, the plane mechanism balance weight adds bascule, in order to the inertia force that balanced connecting rod, crank mechanism are in operation, eliminates vibration, reaches the purpose that cold pilger mill runs up.On the two-tube cold pilger mill of the formula same period, adopt the additional bascule of two balance weights.The work period of cold pilger mill time/minute is brought up to 100 times/minute from common＜60.Its oscillation phenomenon obviously reduces, and vibration noise is＜62 decibels, and similar machine vibration noise is＞90 decibels.
Claims (3)
1, the two-tube cold pilger mill toggle of periodic that has two balance weights, comprise motor input rotating shaft, phase gear-box, travelling gear, crank gear, connecting rod, frame, it is characterized in that: the phase gear-box connects two groups of travelling gears, crank gear, the connecting rod of parallel placement, on travelling gear and crank gear balance weight is arranged.
