Description
Technical field:
The utility model relates to the stress metal processing technique field, is a kind of anti-main transmission excess load and the novel rolling mill of parking steel-fastening specifically.
Background technology:
In the stress metal process, the roll roll spacing of milling train (comprising punch) can not be accomplished in the operation of rolling because of active transmission system excess load automatic and adjustable, keep carrying out continuously of the operation of rolling, force outage and at present the safeties of main transmission are generally.Thereby, when being rolled metal and in milling train, being rolled, owing to be rolled change in size, the variations in temperature of metal, be easy to cause the main transmission excess load and stop and cause the steel-fastening accident that the metal that is rolled that also causes upstream process simultaneously interrupts scrapping because of producing.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of novel rolling mill of steel-jam proof is provided, and has mainly solved problems such as shutdown that existing milling train causes because of the main transmission excess load, steel-fastening waste.
To achieve these goals, the utility model is achieved in that a kind of novel rolling mill of steel-jam proof, it comprises framework memorial archway 9, on framework memorial archway 9, establish left roll rotary drum case 4 and right roll rotary drum case 8, on left roll rotary drum case 4 and right roll rotary drum case 8, establish roll 5 respectively, two rolls 5 are connected with drive motors 10 respectively, its special character is to establish hydraulic pressure overflow cylinder 1 between left roll rotary drum case 4 and framework memorial archway 9, hydraulic pressure overflow cylinder 1 is connected with Hydraulic Station 2, Hydraulic Station 2 is connected with control device 3, and control device 3 is connected with drive motors 10 by circuit.
The novel rolling mill of a kind of steel-jam proof of the present utility model, its described hydraulic pressure overflow cylinder 1 is former and later two, can guarantee the milling train smooth operation.
Compared with the prior art the novel rolling mill of a kind of steel-jam proof described in the utility model has following good effect: because of installing hydraulic pressure overflow cylinder assembly additional; can guarantee fully that the operation of rolling do not interrupt because of excess load; can protect motor and roll; guarantee the continuity of production simultaneously; improve the quality of products, reduce waste product.
Description of drawings:
Fig. 1---structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, provide the novel rolling mill that specific embodiment describes a kind of steel-jam proof of the utility model in detail below in conjunction with accompanying drawing.
Embodiment 1, referring to Fig. 1, be processed into framework memorial archway 9, left side roll rotary drum case 4, right roll rotary drum case 8, roll 5, drive motors 10, according to prior art above-mentioned parts are assembled into milling train, be about to left roll rotary drum case 4 and right roll rotary drum case 8 is installed on the framework memorial archway 9, on left roll rotary drum case 4 and right roll rotary drum case 8, roll 5 is installed respectively, two rolls 5 are connected with drive motors 10 respectively, hydraulic pressure overflow cylinder 1 is installed between left roll rotary drum case 4 and framework memorial archway 9, because the roll rotary drum case of milling train is very big, in order to make the milling train running steadily, hydraulic pressure overflow cylinder 1 is former and later two, hydraulic pressure overflow cylinder 1 is connected with Hydraulic Station 2, Hydraulic Station 2 is connected with control device 3, control device 3 is connected with drive motors 10 by circuit, has set in advance certain value in the control device 3, can experience the interior force value of drive motors 10 actual motion current values and hydraulic pressure overflow cylinder 1 with the relays in the timed unit 3.
The novel rolling mill of a kind of steel-jam proof of the present utility model, to hydraulic pressure overflow cylinder 1 fuel feeding, the force value in the hydraulic pressure overflow cylinder 1 reaches when setting value its described Hydraulic Station 2, system's pressurize by main pump, by the overflow valve regulating system pressure of Hydraulic Station 2, unnecessary pressure current oil sump tank; When the pressure switch of Hydraulic Station 2 detected pressure in the hydraulic pressure overflow cylinder 1 and is lower than the setting value of control device 3, the overflow valve of Hydraulic Station 2 was opened, and main pump begins fuel feeding; When the pressure switch of Hydraulic Station 2 detects pressure in the hydraulic pressure overflow cylinder 1 and is higher than the setting value of control device 3; the overflow valve of Hydraulic Station 2 is opened; the 1 beginning overflow of hydraulic pressure overflow cylinder; the setting pressure of off-load to the control device 3; the overflow valve of Hydraulic Station 2 is valves of the oil mass in the control hydraulic pressure overflow cylinder 1, plays the safeguard protection effect.
The novel rolling mill of a kind of steel-jam proof described in the utility model, when working properly, the piston rod of hydraulic pressure overflow cylinder is in full stroke position and transfixion, guarantee the stable of left and right sides roll rotary drum case in the normal operation of rolling, also promptly the spacing of two rolls is constant motionless, the drive motors rotation of roll drives the roll rotation, thereby guarantees to shut out the qualified steel pipe of wall thickness; After the steel pipe that is rolled and internal strain instrument are nipped by the pressure roller rotation simultaneously, the current capacity of drive motors raises, hydraulic pressure in the hydraulic pressure overflow cylinder raises, relay in the control device detects the current load signal of drive motors and the hydraulic pressure signal in the hydraulic pressure overflow cylinder all the time, when this two signal value surpasses the value S1 that presets in the control device, the overflow valve of control device control Hydraulic Station is opened, hydraulic pressure overflow cylinder begins overflow, the roll in left side and the roll rotary drum case in left side are mobile slightly to hydraulic pressure overflow cylinder one side under the roll-force effect, the drive motors current capacity that then drives roll descends, pressure in the hydraulic pressure overflow cylinder descends simultaneously, when the two all drops to preset value S2, the overflow valve of control device control Hydraulic Station cuts out, hydraulic pressure overflow cylinder stops overflow, keep rolling normally, make to be rolled the metal steel pipe and to shut out smoothly.
