Abstract
The utility model provides a stretchable oil pipe device for a vertical extruding machine and relates to an extruding machine. The problems of long length, big through diameter, poor flexibility and difficulty in fixing of the present stretchable oil pipe are solved. A sleeve of the stretchable oil pipe device for the vertical extruding machine is fixed on an upper cross beam; an oil conveying pipe is sleeved in the sleeve; a plug and a conduit are welded at the rear end of the oil conveying pipe; the two ends of the sleeve are respectively provided with seals and are pressed by glands; an oil inlet of the sleeve is externally connected with a flange connector I and is communicated with a cavity between the sleeve and the oil conveying pipe; an oil port at one end of the oil conveying pipe is communicated with the cavity; the oil port at the other end of the oil conveying pipe is connected with a right-angle connector through a flange connector II; and the right-angle connector is connected with a cylinder body of a built-in perforating cylinder. The stretchable oil pipe device is used for conveying oil for the built-in perforating cylinder of the vertical extruding machine and has the advantages that the structure is reasonable, the operation is safe and reliable, the service life is long, and the normal high-pressure oil conveying of the built-in perforating cylinder of the vertical extruding machine during the process of vertical reciprocating motion is ensured.
Description
Technical field
The utility model relates to extruder, and particularly a kind of vertical extruder is used for the telescopic oil tube device of built-in perforation oil supply cylinder.
Background technology
Often adopt built-in perforation cylinder structure in vertical double-acting extruding machine: utilize the main plunger internal punches, consist of perforation cylinder cylinder body, the built-in piston of perforation cylinder cylinder body is finished the action of perforation and backhaul.In the extruder course of work, perforation cylinder cylinder body and piston all will be done and pump, and so just require to adopt the piston of flexible duct connection cylinder body and two hydraulic fluid ports of rod end chamber.
Because perforation cylinder hydraulic fluid port latus rectum is large, perforation cylinder piston stroke is long, and oil liquid pressure is high, so adopt high pressure flexible metallic conduit conveying liquid force feed just very difficult, because large path high-pressure flexible pipe is flexible very poor, bending radius is very large, and long metal hose swings to and fro and is difficult for constraint and fixing in addition.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of vertical extruder telescopic oil tube device is provided, and solves that existing telescopic oil tube length is long, latus rectum is large, flexible poor, is difficult for fixing problem.
The utility model is achieved through the following technical solutions:
A kind of vertical extruder telescopic oil tube device, it is characterized in that: described telescopic oil tube device comprises: overcoat, petroleum pipeline, plug, conduit, cover, sealing and gland, described overcoat is fixed on the entablature, the interior suit of overcoat petroleum pipeline, petroleum pipeline rear end welding plug, plug and conduit welding, install I number between one end of overcoat and the conduit and seal and compressed by the I gland, install II number between the other end of overcoat and the petroleum pipeline and seal and compressed by the II gland; The external I bump joint of the oil-in of overcoat also is communicated with cavity between overcoat and the petroleum pipeline, the hydraulic fluid port of petroleum pipeline one end is communicated with cavity between overcoat and the petroleum pipeline, the hydraulic fluid port of the petroleum pipeline other end is connected with angle coupling by the II bump joint, and angle coupling is connected with built-in perforation cylinder cylinder body.
Described cover is bolted on outer putting.
The utility model compared with prior art has the following advantages and beneficial effect:
Owing to fixing a kind of overcoat at the vertical extruder entablature, be set with again petroleum pipeline in the overcoat, petroleum pipeline one end is connected with built-in perforation cylinder cylinder body by bump joint, angle coupling.Therefore, consisted of a kind of telescopic oil tube device, during extruder work, petroleum pipeline is along with the movement of perforation cylinder cylinder body, can be in overcoat free-extension, be equivalent to tubing length and do not stop to change, satisfied the in the course of the work changing requirement of relative position of oil cylinder fully.The utility model is used for the oil transportation of the built-in perforation cylinder of vertical extruder, has rational in infrastructurely, and handling safety is reliable, long service life, and can guarantee the built-in perforation cylinder of vertical extruder when pumping, the advantage of normal conveying high-pressure oil.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is described in further detail by preferred embodiment below in conjunction with accompanying drawing:
The specific embodiment
As shown in Figure 1, 2, a kind of vertical extruder telescopic oil tube device comprises: overcoat, petroleum pipeline, plug, conduit, cover, sealing and gland, described overcoat 1 is fixed on the entablature 10, overcoat 1 interior suit petroleum pipeline 2, petroleum pipeline 2 can freely move up and down overcoat 1 is interior, petroleum pipeline 2 rear end welding plugs 6, plug 6 and conduit 7 welding, I number sealing 4-1 is installed between one end of overcoat 1 and the conduit 7 and compressed by I gland 3-1, install between the other end of overcoat 1 and the petroleum pipeline 2 and seal 4-2 for II number and compressed by II gland 3-2; The oil-in B external I bump joint 8-1 of overcoat 1 also is communicated with cavity between overcoat 1 and the petroleum pipeline 2, the hydraulic fluid port C of petroleum pipeline 2 one ends is communicated with cavity between overcoat 1 and the petroleum pipeline 2, the hydraulic fluid port D of petroleum pipeline 2 other ends is connected with angle coupling 9 by II bump joint 8-2, and angle coupling 9 is connected with perforation cylinder cylinder body.
Be bolted on institute's overcoat 1 and state cover 5, conduit 7 is covered, prevent that the impurity such as dust from adhering on the conduit 7.
Hydraulic oil enters from the A mouth of I bump joint 8-1, and the B mouth by overcoat 1 enters the cavity between overcoat 1 and the petroleum pipeline 2, and the C mouth by petroleum pipeline 2 enters petroleum pipeline 2 inside again, and last hydraulic oil is discharged by the D mouth of angle coupling 9.
During this vertical extruder work, angle coupling 9 is along with perforation cylinder cylinder body pumps, and petroleum pipeline 2 and overcoat 1 are done relative motion, do not stop to change corresponding to petroleum pipeline 2 length, can guarantee that all the time hydraulic oil is from the A mouth to the unimpeded conveying of D mouth.
