Description
Technical field
The present invention relates to a kind of on large-scale fast pressure machine to slide block movement inertia carry out balance from the supercharging balance and buffer device, simultaneously can realize bidirectional balanced cushioning effect, to be adapted in the quick course of work of forcing press, inertia impact owing to the increase and decrease of slide block acceleration causes belongs to the high forging equipment of automaticity and manufacturing technology field.
Background technology
Along with the fast development of modern mechanical industry, also stride forward in the continuous direction to automation, precise treatment, intellectuality and high-speed and high-efficiency as the forcing press of forging equipment.Realizing automation, when reducing labor strength, more need the harm of avoiding equipment powerful vibration, impact, noise pollution in service to bring.The just anti-limited slip block of the effect of traditional forcing press bascule is when moving downward, its weight is accelerated motion parts, cause " in advance ", cause the running part bump, this balance mode is less for inertia impact and balanced action, therefore generally be only applicable to the moving equilibrium of middle-size and small-size low speed forcing press, but obviously incompatible for large-scale fast pressure machine.Because large-scale fast pressure machine is in running, the kinetic characteristic of toggle causes the acceleration of slide block movement periodically to change, the also thereupon variation of generating period of inertia force by the acceleration initiation, for large-scale fast pressure machine, the inertia force that this acceleration causes has not been allowed to ignore, particularly have on the multi-link lever press of quickreturn characteristics, the peak value of acceleration increases more obvious, thereby cause equipment in running, to produce larger noise and vibration, had a strong impact on the normal use of equipment.
Summary of the invention
The object of the invention is to provide a kind of forcing press from the bidirectional balanced buffer unit of supercharging, purpose is to realize moving equilibrium and inertia impact cushioning balance in big-and-middle-sized fast pressure machine, in order to reduce elliptical gear and the inertia impact of equipment, alleviate vibration and reduce noise, improve the manually-operated environment, and effectively prolong press and mold use life-span.

The present invention cooperates bidirectional balanced device and self-supercharging device at forcing press, the cushioning balance of the inertia force that the acceleration when by bidirectional balanced device slide block and mould being moved downward impulsive force that system is produced and slide block backhaul produces, elliptical gear and inertia impact have namely been reduced, it alleviates vibration and reduces noise, improve the manually-operated environment, and effectively prolong press and mold use life-span; Self-supercharging device is used for controlling, regulating pressed gas, to guarantee the normal operation of bidirectional balanced device.
Bidirectional balanced device of the present invention comprises a balance cylinder, gas receiver, the free end of the piston rod of described balance cylinder connects with the slide block of corresponding forcing press, on the end cap at the two ends of described balance cylinder, pore is set respectively, the gas outlet of described gas receiver is communicated with the pore at described balance cylinder two ends respectively by tracheae, with tracheae that rod chamber and the rodless cavity of described balance cylinder are communicated with on a magnetic valve is set respectively.
The present invention pours the activity that pressed gas comes the air balance cylinder by rod chamber and the rodless cavity at balance cylinder, and balance cylinder is by the free end Bonding pressure machine slide block of piston rod; Rodless cavity exhaust during the air inlet of bascule rod chamber, the holder power of equilibrant force for slide block is made progress, the equilibrant force of this moment is mainly moving equilibrium, i.e. and the transmission system that anti-limited slip block and the downward leading motion that produces of mould deadweight causes is impacted; During the exhaust of bascule rodless cavity air inlet rod chamber, equilibrant force is to the downward counter-pressure of slide block, and this downward counter-pressure mainly is when eliminating the press ram quick return, because the acceleration inertia force that the quickreturn characteristics of multi-connecting-rod mechanism produces; Up and down two air inlets of balance cylinder are controlled its break-make by magnetic valve, control with this and move downward balance and the balance that moves downward; Reduced like this elliptical gear and inertia impact, it alleviates vibration and reduces noise, improves the manually-operated environment, and effectively prolongs press and mold use life-span.
Self-supercharging device of the present invention comprises pressure charging valve, described pressure charging valve is arranged between described gas receiver and the described balance cylinder, the air inlet of described pressure charging valve is connected with the gas outlet of described gas receiver by pipeline, and the gas outlet of described pressure charging valve is connected by the air inlet of pipeline with described two magnetic valves respectively.
Self-supercharging device of the present invention is in order to remedy the low undesirable defective of the less counterbalance effect of equilibrant force of compressed air pressure, this cover balance sysmte has also been set up self-supercharging device, but the time of equal balancing control supercharging balance when slide block moves downward or move upward, come the suddenly inertial impact force of increase of balance with this equilibrant force that doubles.
The present invention connects respectively a rotary encoder on described each electromagnetic gas valve, described each rotary encoder is electrically connected with described each magnetic valve respectively; This device is by obtaining the crank angle of forcing press by rotary encoder, thereby sends control instruction according to the angle position of crank by PLC, realizes the accurate control of commutating period with this; The PLC programmable controller is in order accurately to control the commutate time of balance and the time of supercharging balance, and it can accurately set the illusion actuation time of magnetic valve, and the control source of PLC programmable controller is the rotary encoder of forcing press.
The present invention connects a pressure-reducing valve at the tracheae that passes through of the pressure relief opening of described pressure charging valve, between described pressure-reducing valve and pressure charging valve magnetic valve is set; In the balance adjustment process, pressed gas has residue after by pressure charging valve, and remaining gas is then got rid of from pressure-reducing valve, and in sum, pressure-reducing valve mainly plays the effect that pressure is adjusted at this, and magnetic valve herein is used for controlling the switch of pressure-reducing valve.
