Description
Technical field
The utility model relates to oven, particularly a kind of energy recycle device for hydraulic system of walking-beam furnace.
Background technique
In bar production, according to technological requirement, steel billet needs to pass through oven before entering rolling mill practice.Oven is one of production line of bar visual plant, and its effect is to the rolling temperature of technological requirement by heating steel billet.
Different according to heating furnace structure, oven is divided into pusher-type furnace and walking beam furnace.Hydraulic stepping oven is large with its bearing capacity, and steel billet temperature controls flexibly, and many-sided advantages such as stable movement is reliable are widely used.
The stepping mechanism of walking beam furnace comprises: step rate, be elevated the composition such as oblique rail, fixed beam and lifting hydraulic cylinder, translation oil hydraulic cylinder.Wherein step rate rising and decline by lifting hydraulic cylinder along lifting guide plate inclined-plane drive, move forward and backward by translation Driven by Hydraulic Cylinder.Walking beam furnace completes heating and the conveying of steel billet by the do action of the rising of step rate, advance, decline and retrogressing.
When step rate rising holds up steel billet, lifting hydraulic cylinder need overcome whole load acting, and power stage is very large, and thrust required during walking beam transition is relatively little.When steel billet declines, due to Action of Gravity Field, lifting hydraulic cylinder bears negativity load, and hydraulic system provides back pressure that step rate is steadily declined, and this operating mode makes the power output pole of hydraulic system unbalanced and Hydraulic System Fever, causes energy dissipation.
For above-mentioned deficiency, need to optimize existing hydraulic system, avoid when steel billet declines, due to gravity acting, the energy loss of system.The recovery of Energy Efficient when simultaneously system being declined, and be used in promotion step rate rising acting.
Model utility content
The purpose of this utility model is to overcome the hydraulic system unbalanced problem of power stage when holding up steel billet and decline steel billet in existing hydraulic stepping oven, thus provides a kind of energy recycle device of potential energy of system when effectively can utilize decline.
To achieve these goals, the utility model provides a kind of energy recycle device for hydraulic system of walking-beam furnace, comprising: oil hydraulic cylinder 1, energy storage unit 2, energy supplement unit 3; Wherein, described oil hydraulic cylinder 1 is multistage hydraulic cylinder, and it includes C mouth, and described C mouth is connected with energy storage unit 2 as energy storage chamber; Described energy supplement unit 3 is connected with energy storage unit 2, for being energy storage unit 2 supplementary pressure and flow.
In technique scheme, described energy storage units 2 is a bag type accumulator, for storage liquid force feed.
In technique scheme, described energy supplement unit 3 comprises: gear pump, control valve group, it is installed in the oil circuit of energy storage unit 2.
The utility model has the advantage of:
Potential energy when energy recycle device for hydraulic system of walking-beam furnace of the present utility model is by declining step rate in hydraulic circuit stores, and discharges and do work when step rate rises; While the potential energy of this device system when effectively utilizing decline, greatly reducing the working pressure of whole system, improve the working life of hydraulic element, commonality, strong adaptability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the energy recycle device for hydraulic system of walking-beam furnace of the present utility model.
Embodiment
Now the utility model will be further described by reference to the accompanying drawings.
With reference to figure 1, the energy recycle device for hydraulic system of walking-beam furnace of the present utility model comprises: oil hydraulic cylinder 1, energy storage unit 2, energy supplement unit 3; Wherein, described oil hydraulic cylinder 1 is multistage hydraulic cylinder, and it includes A mouth, B mouth and C mouth, and described A mouth is connected with Proportional valve, and for realizing the lifting of step rate, described B mouth is connected with Proportional valve, for realizing the decline of step rate; Described C mouth is connected with energy storage unit 2 as energy storage chamber; Described energy supplement unit 3 is connected with energy storage unit 2, for being energy storage unit 2 supplementary pressure and flow.
Below all parts in device is described further.
Described energy storage unit 2 is an accumulator, and in one embodiment, described energy storage units 2 is a bag type accumulator.Can storage liquid force feed in described accumulator.
Described energy supplement unit 3 is installed in the oil circuit of energy storage unit 2, and in one embodiment, this unit comprises: gear pump, control valve group.If energy storage unit 2 exists the situation of the pressure loss, flow loss, the pressure in energy supplement unit 3 makeup energy storage element 2 and flow, make it to adapt with working flow, pressure.The type selecting of energy supplement unit 3, by calculating, makes the working flow of itself and hydraulic system of walking-beam furnace, pressure adapts.
The working procedure of the energy recycle device for hydraulic system of walking-beam furnace of the present utility model is as follows:
When step rate declines, oil hydraulic cylinder 1 is owing to being subject to Action of Gravity Field, and the hydraulic oil with pressure potential passes through the C mouth of oil hydraulic cylinder 1 stored in energy storage unit 2, thus is got up by stored energy.When step rate rises, the hydraulic oil in energy storage unit 2 jointly promotes hydraulic cylinder piston by the C mouth of oil hydraulic cylinder 1 and the pressure oil of proportional valve control and does work.
The utility model is a kind of for hydraulic system of walking-beam furnace energy recycle device, effectively utilize multistage hydraulic cylinder and accumulator as critical component, solve that hydraulic system of walking-beam furnace pressure is higher, energy consumption is higher, the problem such as potential energy waste when declining.Relative to the hydraulic system in walking beam furnace stepping mechanism, this device strong adaptability.Relatively conventional hydraulic system of walking-beam furnace design, although the design and devdlop of this device is less, commonality is strong.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted.Although be described in detail the utility model with reference to embodiment, those of ordinary skill in the art is to be understood that, the technical solution of the utility model is modified or equivalent replacement, do not depart from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
