Described ball groove is provided with groove and aperture.
The Surface Machining of described piston has thread groove, and the inside of described piston is processed with groove.
The cutting equipment of New Large Caliber tubing of the present invention, cutoff tool assembly can follow rotor turns, and can do rectilinear motion along the diametric(al) of rotor by knife rest.By the resultant motion of cutter, carry out the cut-out of tubing.Cutting moment greatly and steadily, driving is simple, equipment operates steadily reliably, noise is low, efficiency is high, applied widely, production cost is low, can be used for the cut-out of cutting large-diameter pipe material.
Specific embodiment:
As shown in Fig. 1 to Figure 14, this equipment comprises whirligig and knife assembly: described whirligig comprises shell and the rotor being arranged on enclosure, rotor is evenly distributed with 18 pistons, and piston tip installs piston shoes, the other end of piston shoes is close to swash plate, and swash plate is fixed on shell by nut; Cutoff tool assembly comprises knife rest cylinder, knife rest and cutter, and 18 knife rest cylinders are arranged on the diametric(al) of rotor inner opposite end, and knife rest is arranged on knife rest cylinder by nut, and Cutting tool installation manner is on knife rest, and this equipment also comprises the oil distribution casing be fixed on shell.
Described rotor is uniform-distribution with 18 plunger shaft, for installing piston and injection liquid force feed, the Surface Machining of described piston has gone out thread groove, and inside processes groove, so that hydraulic oil is introduced.
The sphere of described piston shoes and described piston contact processes groove and aperture, so that hydraulic oil is introduced, play lubrication.
Described cutoff tool group also comprises stator, with fixing cutoff tool group, in order to limit the space of knife rest.
Described cutter has the profile feature of lathe tool, and cutting utilizes the operation principle of sawtooth, and described cutter is independent mutually.
Described knife rest and described piston two place are slidably matched middle employing clearance seal; Described rotor and be furnished with between dish and adopt gasket seal to seal.
Described swash plate and base are integrated not to be needed to retighten, and makes that this apparatus structure is compact cuts good sealing effect.
In specific implementation process, as shown in Figure 1, Figure 2 and Figure 3, oil distribution casing 1, shell 2 and swash plate 3 are linked together by nut; As described in Fig. 4 and Fig. 6, cutter 5 is arranged on knife rest 4, and knife rest 4 is fixed on rotor 10 by fixed mount; As described in Fig. 4 and Fig. 5, the orbicule at piston 8 top and the concave spherical surface of piston shoes 7 are linked together, and the planar top of piston shoes 7 is on the inclined-plane of swash plate 3.
Operation principle:
As shown in Figure 4 and Figure 5, rotor 10 cylinder body inner carrier 8 is axial arranged, when the hydraulic oil with pressure is by oil distribution casing 1 access to plant oil suction chamber, piston shoes 7 are subject to active force and press to swash plate, and swash plate produces a reaction force to piston shoes, this reaction force axial thrust load (being parallel to plunger axis) and pressure balance suffered by plunger, the vertical stress component (perpendicular to plunger axis) of reaction force produces torque to rotor 10, drive rotor 10 to rotate, thus band movable knife rack 4 and cutter 5 rotate.Meanwhile, hydraulic oil enters knife rest 4, promotes cutter 5 and moves to the center of circle in diametric(al).In the process, cutter 5 does rectilinear motion until point of a knife withstands outer wall of steel pipe under the promotion of pressure oil, and meanwhile, the knife rest for being installed with cutter is followed rotor 10 and forwarded to.Formed by the synthesis cutter 5 of motion and a kind ofly not only forwarded to along with rotor but also diametrically done the compound movement of rectilinear motion, thus cutter 5 defines the motion of the cutting of the similar circular saw blade drawn close to the center of circle gradually, thus bigbore tubing is cut.
Specific works process:
Large pipe enters into the inner chamber of cutting equipment by conveyer, and after reaching Cutting Length, control section sends instruction.There is the fuel feed hole of hydraulic oil by oil distribution casing 1 of pressure, enter into the piston 8 of the rotor 10 of device interior, and piston 8 is produced to the thrust F of a straight line.This power F acts directly on piston shoes 7, and makes piston shoes 7 be close to swash plate 3.Meanwhile, swash plate 3 pairs of piston shoes 7 produce the reaction force of a vertical and swash plate 7.This reaction force N component N1 in the horizontal direction and hydraulic oil balance the power F that piston produces, and the component N2 of the vertical direction of this reaction force N produces moment of torsion to rotor 10 center, drive rotor turns.And hydraulic oil is entered into by the oil pocket of rotor 10 and is arranged in 18 knife rest cylinders 4 of rotor 10 inwall, and promote cutter 5 and do rectilinear motion forward.By the promotion of the hydraulic oil in the drive of rotor 10 and knife rest cylinder 4, cutter 5 does one and both rotates, again along the resultant motion of knife rest cylinder 4 linear advancement around equipment center.Cutter 5 defines a kind of cutting movement of the similar circular saw blade drawn close to the center of circle gradually, thus bigbore tubing is cut off.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
