Abstract
A hydraulic pipe cutter for plastic pipes is provided with an oil storage device, steel balls, a return valve, a pressurizing cylinder, a pressing handle, a piston rod, a spring, an injection cylinderand a knife blade. When the pressing handle is pressed to drive a pressure rod to press oil inside the pressurizing cylinder, a steel ball on one side of the pressure rod moves towards and stops an oil inlet of the oil storage device, a steel ball on the other side of the pressure rod moves towards the injection cylinder and pushes the piston rod to move the knife blade so as to cut an upper plastic pipe clamped on one side of a track pipe of the knife blade, after loosening the return valve, pressure in the pressurizing cylinder is released, and then the piston rod is rebounded via the spring sleeved on the outer diameter of the piston rod to drive the knife blade to return. The hydraulic pipe cutter has the advantages that the hydraulic pipe cutter can conveniently cut PPR pipes, saveslabor, and is extremely high in efficiency.
Description
Technical field
The utility model relates to a kind of plastic tube hydraulic pressure pipe cutter, belongs to mechanical field.
Background technology
Prior art is to the PPR pipe (abbreviation of atactic copolymerized polypropene (Polypropylene-Random).Or claim three type polypropylene) cutting, adopt scissors more, effort very, efficient is also very low.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of plastic tube hydraulic pressure pipe cutter.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of plastic tube hydraulic pressure pipe cutter, oil conservator, steel ball, return valve, pressurized cylinder, pressure handle hand, piston rod, spring, shot sleeve, blade are arranged, oil conservator is that hollow has oil, and oil-in is arranged; One side of oil conservator is a pressurized cylinder, and pressurized cylinder is porose to communicate with oil conservator, has the pressure handle hand to be fixed by set bolt on the external diameter of pressurized cylinder, and the inner chamber that has press rods to pass through hole and pressurized cylinder on the external diameter of pressurized cylinder is connected; Both sides in press rods in the inner chamber of pressurized cylinder have steel ball respectively, and the external diameter of steel ball and the intracavity diameter of pressurized cylinder are complementary; Also have the valve rod of return valve and the inner chamber of pressurized cylinder to connect on the external diameter of pressurized cylinder; The opposite side of pressurized cylinder has shot sleeve, and shot sleeve communicates with the inner chamber of pressurized cylinder, and the inner chamber of shot sleeve has piston rod, and the external diameter of piston rod has spring to connect; One end of piston rod is connected with blade; Have blade orbitron and shot sleeve an end link by spiral shell and connect; Blade is fixed on the blade orbitron; One side of blade orbitron has otch; There is stationary pipes to fix on the external diameter of its cut ends by screw.
Drive oil in the press rods extruding pressurized cylinder when the pressure handle hand is depressed, with the steel ball of press rods one side to the oil-in motion of oil conservator and block the oil-in of oil conservator; The steel ball of press rods opposite side moves with the drive blade to shot sleeve motion and promotion piston rod, and the last plastic tube that is installed on blade orbitron one side is cut; Behind loosening return valve, the pressure in the pressurized cylinder discharges, and the spring that is enclosed within the piston rod external diameter rebounds piston rod and drives the blade travelling backwards.
The beneficial effects of the utility model are: can cut the PPR pipe easily, laborsaving, efficient is also very high.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the utility model schematic diagram.
