Abstract
The utility model relates to a mold oscillation load-reducing device, which is composed of a vibrating frame, bearing supports and a base, a set of airbag type cylinders are respectively mounted on the bearing supports at both sides under a supporting axle of the vibrating frame, and the expansion bag thereof is composed of two to five sections. The utility model has the functional effects that: when the vibrating frame vibrates downwards, the airbags absorb the energy and reduce the impact, and when the vibrating frame vibrate upwards, the airbags release the energy and assist a motor to do work. Therefore, the utility model ensures the constant sine vibration wave, as well as utilizing the characteristics of the airbags to reduce the system loading.
Description
Technical field
The utility model relates to the continuous casting technology field, is specially adapted to reduce the device of mold oscillation to the driving arrangement infringement.
Background technology
Mould vibration device is the nucleus equipment of conticaster, and mold oscillation is significant to the production efficiency and the precision of conticaster.Mould vibration device of the prior art adopts the eccentric ratio formula usually, realizes sine wave oscillations by linkage.Wherein crystallizer is from weighing 12 tons, vibration frame is from weighing more than 20 tons, bring shock loading must for when this mechanism realizes vibration each bearing and parts, the wearing and tearing meeting in the various gaps of itself increases gradually, so not only brings the vibration precision that endangers but also influence crystallizer to machinery.Though the device of leaf spring vibration has overcome the deficiency of eccentric ratio formula, because the vibrating device own wt is big, impacts and cause equipment attrition fast greatly, still there is following defective:
Noise was big when 1, mould vibration device was worked, and the fulcrum roller of walking beam damages too fast, caused mold oscillation beam and under(-)chassis to interfere, and made vibration amplitude can not get guaranteeing.In case the crystallizer backing must be shut down processing, each interim processing needs about 2 hours.
2, reductor vibration is big, and shock loading causes reducer gear, damage of bearings too fast, and the reductor life-span reduces simultaneously, recondition expense increases.
3, the mold oscillation connecting lever need be changed once half a year, must change 3 kinds of imported bearings totally 16 covers at every turn.
4, fault takes place frequently and causes spot check intensity big.
By retrieval, in the prior art, the patent No. is 02158207, name is called the Chinese invention patent of " conticaster crystallizer vibrating device ", introduce a kind of conticaster crystallizer vibrating device, it is characterized in that flat spring is inner is connected with shake table, and the high-precision motion track of realization crystallizer under dither has and do not wear and tear, need not keep in repair and the characteristics of reliable operation.But this device still exists some defective of spring force-reducing device.
Summary of the invention
The purpose of this utility model provides a kind of mold oscillation force-reducing device, and the mold oscillation beam is set up force-reducing device, reaches the purpose that reduces to wear and tear and reduce motor load, prolong the service life of equipment thereby reduce each point load.
The utility model is achieved through the following technical solutions:
The mold oscillation force-reducing device, this device is made of vibration frame, supporting base, base, it is characterized in that: respectively lay one group of balloon-type cylinder on two-side supporting seat below the bolster of vibration frame.
The flexible capsule of described balloon-type cylinder is made up of the 2-5 joint.
The beneficial effects of the utility model are: air bag absorbed the energy minimizing and impacts the stand-by motor that releases energy when upwards vibrating acting when vibration frame vibrated downwards.So both guaranteed that the sinusoidal vibration ripple was constant, and utilized the characteristic of air bag to reduce the load of system again.
Description of drawings
Fig. 1 is the structural representation of mold oscillation force-reducing device.
The specific embodiment
See Fig. 1, the mold oscillation force-reducing device, this device is made of vibration frame 1, supporting base 3, base 4, respectively lays one group of balloon-type cylinder 2 on two-side supporting seat 3 below the bolster of vibration frame 1.
The flexible capsule of described balloon-type cylinder is made up of the 2-5 joint.
The utility model utilizes the endergonic characteristic of air bag, and one group of air bag is respectively laid in both sides below mold oscillation framework crystallizer back shaft.Concrete scheme is as follows:
1, adjusts the inertia force of mold oscillation mechanism.According to drawing, theoretical calculating crystallizer, walking beam, the gravity of feedwater framework and the frictional force of crystallizer and strand, and they are at the inertia force (frictional force noninertia power) of (under the maximum frequency of oscillation) under the highest pulling rate.
2, determine the counteracting power of force-reducing device.According to gravity, frictional force, with inertia force and power, calculate the power that force-reducing device should be offset.Calculate principle and be gravity be greater than other power and.
3, according to the result of calculation of power, design force-reducing device.As buffer, its operating pressure is 0.2-0.4Mpa with air bag, and model is M31142, diameter 400mm, and stroke 380mm is installed on the supporting base, connects by bolt.
This balloon-type cylinder belongs to the single-acting cylinder of short stroke, high thrust.General cylinder diameter is at 150---400mm, and stroke depends on the joint number of flexible capsule.It is to conduct oneself with dignity by the elastic force of leather bag or load to realize that this cylinder returns.
The flexible capsule of this balloon-type cylinder often is made up of two joints or three joints.Material can be selected the elasticity neoprene for use.This cylinder is used for axial location and requires very not strict part, can be used for vehicle suspension system, equipment vibration isolation and uses etc.
4, the actual needs according to force-reducing device designs pneumatic operated valve group and pneumatic cabinet.
5, the on-the-spot source of the gas of preparing, pipe arrangement is to pneumatic cabinet, and pneumatic cabinet is installed in single current mold oscillation frame facet, again by pipe arrangement both sides air bag under the vibration frame.Air pressure is regulated by the pneumatic operated valve group.
