Abstract
The utility model relates to a centrifugally casted hydraulic pipe tensioner, comprising a pipe tensioner seat (4), characterized in that: a hydraulic winch (7) is arranged on the back end of the pipe tensioner seat (4) and controlled by a hydraulic system, an oil inlet of the hydraulic winch (7) is connected with an electromagnetic directional valve (8), the electromagnetic directional valve (8) is connected with a pressure adjustment valve (9), the pressure adjustment valve (9) is connected with a speed adjustment valve (10), the speed adjustment valve (10) is connected with a hydraulic pump station (11) and an oil return port of the hydraulic winch (7) is connected with the hydraulic pump station (11). The centrifugally casted hydraulic pipe tensioner uses the hydraulic winch to pull out a pipe blank and also uses a hydraulic element connected with the pipe tensioner to adjust the tensile force of the hydraulic winch, thus the pipe-tension demoulding speed is stable, the service life of the hydraulic winch is increased and the linearity of the pipe blank is ensured.
Description
(1) technical field
The utility model relates to a kind of hydraulic pressure trombone slide mechanism of centrifugal casting.
(2) background technology
Centrifugal casting is that the pipe fitting density of being produced is higher with pipe cast molding under centrifugal force field, and product yield is high, so it is the main method that pipe fitting is produced.After pipe is cast in type tube and accomplished, need utilize the interior hoist engine of bench that pipe is pulled out type tube and accomplish the demoulding, so that carry out spun casting next time.
The linearity of the pipe that centrifugal casting forms is an important indicator weighing quality of tube blank steel, and when coming trombone slide with pneumatic or electrical hoist, hoist engine is unstable in the past; Can shake; Cause high temperature pipe and carrying roller after the demoulding to produce bump through regular meeting, cause pipe flexural deformation, percent defective is high; The pulling force of electrical hoist was unadjustable in the past, can not satisfy the variation of the required knockout press of different size pipe, and electrical hoist is fragile under alternation heavy load operating mode; And the hoist noise is bigger with vibration.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of trombone slide quality higher, pulling force adjustable size, and the hydraulic pressure trombone slide mechanism of the less centrifugal casting of noise.
The purpose of the utility model is achieved in that
The hydraulic pressure trombone slide mechanism of the utility model centrifugal casting comprises the trombone slide support, and said trombone slide support is provided with carrying roller; Said trombone slide support below is provided with elevating mechanism, and the rear end of said trombone slide support is provided with hydraulic wireline winch, and said hydraulic wireline winch is controlled by hydraulic system; Said hydraulic system comprises solenoid directional control valve, pressure-regulating valve, speed-regulating valve and hydraulic power unit; The oil-in of said hydraulic wireline winch links to each other with solenoid directional control valve, and said solenoid directional control valve links to each other with pressure-regulating valve, and said pressure-regulating valve links to each other with speed-regulating valve; Said speed-regulating valve links to each other with hydraulic power unit, and the oil return opening of said hydraulic wireline winch links to each other with hydraulic power unit.
Compared with prior art, the beneficial effect of the utility model is:
The hydraulic pressure trombone slide mechanism of the utility model centrifugal casting adopts hydraulic wireline winch that pipe is pulled out; And regulate the hydraulic wireline winch pulling force through the Hydraulic Elements that are attached thereto; Make that the trombone slide stripping rate is steady; So just, improve the security of the trombone slide demoulding and the service life of hydraulic wireline winch, also guaranteed the linearity of pipe.
(4) description of drawings
Fig. 1 is the structural representation of the hydraulic pressure trombone slide mechanism of the utility model centrifugal casting.
Fig. 2 is the hydraulic schematic diagram of hydraulic wireline winch among Fig. 1.
Wherein: centrifugal casting machine 1, type tube 2, pipe 3, trombone slide support 4, carrying roller 5, elevating mechanism 6, hydraulic wireline winch 7, solenoid directional control valve 8, pressure-regulating valve 9, speed-regulating valve 10, hydraulic power unit 11.
(5) specific embodiment
Referring to Fig. 1; The utility model relates to a kind of hydraulic pressure trombone slide mechanism of centrifugal casting, comprises trombone slide support 4, and said trombone slide support 4 is provided with carrying roller 5; The rear end of said trombone slide support 4 is provided with hydraulic wireline winch 7; Said hydraulic wireline winch 7 can utilize steel wire rope pulling pipe 3, and said trombone slide support 4 belows are provided with elevating mechanism 6, and said elevating mechanism 6 is used to adjust the face height of trombone slide support 4.
Like Fig. 2; Said hydraulic wireline winch 7 is controlled by hydraulic system, and said hydraulic system comprises solenoid directional control valve 8, pressure-regulating valve 9, speed-regulating valve 10 and hydraulic power unit 11, and the oil-in of said hydraulic wireline winch 7 links to each other with solenoid directional control valve 8; Said solenoid directional control valve 8 links to each other with pressure-regulating valve 9; Said pressure-regulating valve 9 links to each other with speed-regulating valve 10, and said speed-regulating valve 10 links to each other with hydraulic power unit 11, and the oil return opening of said hydraulic wireline winch 7 links to each other with hydraulic power unit 11.
Like Fig. 1, the front end of said base 4 is provided with centrifugal casting machine 1, and said centrifugal casting machine 1 is put on the shelf and is provided with type tube 2, is placed with pipe 3 in the said type tube 2.
The hydraulic pressure trombone slide mechanism of the utility model centrifugal casting in use pipe 3 in the type tube 2 of centrifugal casting machine 1, cast accomplish after; Operation solenoid directional control valve 8 is emitted the steel wire rope in the hydraulic wireline winch 7 earlier; This moment, speed-regulating valve 10 transferred to quick position, and the end of itself and pipe 3 is fixed.Control the magnetic valve switching-over subsequently and begin to receive rope; Pressure-regulating valve 10 transfers to the pulling force of hydraulic wireline winch and the corresponding value of thrust of pipe 3 demouldings; When steel wire rope tightens up, speed-regulating valve 10 is transferred to position at a slow speed; After pipe 3 is pulled, can speed-regulating valve 10 be transferred to the middling speed position, all pull out type tube 2 until pipe 3.11 of hydraulic power units are responsible for providing hydraulic wireline winch 7 required pressure oil.After the pipe casting of same specification batch is accomplished,, only need regulate pressure-regulating valve again, make hydraulic wireline winch have and the corresponding value of thrust of the pipe demoulding if will change type tube.
