The utility model adopts the planetary reducer output shaft directly to be connected transmission with the cutting knife main shaft, its compact conformation, and space hold is little, and is easy to use.The utility model is taked the hydraulic control tool feeding, has that centripetal force is big, feeding characteristics stably.During work, transmit pressure by hydraulic pump and give cutter, the cutter rotation is cut, and drives the workpiece rotation by the frictional force that cutter and workpiece tubing produce, and finishes the cutting of pipe.The utility model is applicable to the tubing of the big caliber of cutting, and its cutting speed is fast, work efficiency is high, and cut quality is good, and equipment is reliable; Be particularly suited for cutting the tubing that external diameter surpasses 165mm, tube outer diameter is unrestricted substantially.
Description of drawings
Fig. 1 is the front view of a kind of electric hydaulic pipe cutting machine of the present utility model.
Fig. 2 is by vertical view shown in Figure 1.
Fig. 3 is by right view shown in Figure 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of electric hydaulic pipe cutting machine comprises frame 12, motor 3, cutting knife 1 and knife rest, also comprises the planetary reducer 2 that is connected with motor 3, and the hydraulic means that is installed on the frame 12 control tool feeding amount.
Knife rest is an elongated knife rest 4, and knife rest 4 is perpendicular to cutting knife 1 main shaft.Cutting knife 1 is installed in the outside of frame 12, makes that thus to change cutter aborning very convenient, fast, and does not need the professional also can be from line operate.As required, also cutter can be mounted to medium spacing.
Hydraulic means comprises the hydraulic cylinder 7 that is installed in knife rest 4 left ends, and the push rod 6 that is connected with hydraulic cylinder 7 is installed in hydraulic pump 8, controller and pressure-relief valve 11 on the frame 12.
The output shaft of planetary reducer 2 directly is connected with cutting knife 1 main shaft, and motor 3, planetary reducer 2, cutting knife 1 main shaft three are arranged on the same axis.The housing of planetary reducer 2 and knife rest 4 right-hand members are rigidly connected.Knife rest 4 left ends are connected with the push rod 6 of hydraulic means.The place of taking back, knife rest 4 center is provided with bearing pin 5, and on frame 12, knife rest 4 left and right ends center on turning down on the bearing pin 5 to knife rest 4 by bearing pin 5 bearings.
The roller frame 14 that can support heavy caliber pipe is set under the cutting knife 1, and roller frame 14 links into an integrated entity with frame 12.Roller frame 14 is provided with the roller 13 that can make heavy caliber pipe 21 rotate and prevent axial float.The bore of cutting knife 1 incising pipes is unrestricted substantially, and special in the tubing greater than the 165mm bore, cutting speed is fast, quality good.Because tubing 21 can rotate on roller frame 14, so cutting knife 1 is in the incising pipes process, and cutting knife 1 produces active force on tubing 21 tangent to periphery directions, and tubing 21 rotates along with the rotation of cutting knife 1, impels cutting knife 1 evenly incision on tubing 21 circumferential wall.The hydraulic means push rod 6 of the amount of feeding of cutting knife 1 by being positioned at knife rest 4 left ends be by hydraulic control,
