Abstract
The utility model discloses a hydraulic expanding and pulling machine which comprises a machine frame. A motor, an oil pump, a reversing switch and a hydraulic cylinder are arranged on the machine frame; the oil pump is connected with the reversing switch and the hydraulic cylinder through an oil pipe; rollers are arranged at the lower part of the machine frame; a rotating shaft of the motor arranged on the machine frame is connected with the oil pump through a shaft coupling; a spring balance is also arranged on the machine frame; a wire rope is mounted at one end of the spring balance; the other end of the wire rope moves around a movable pulley and a fixed pulley, and then is fixed on the machine frame; a tractor is mounted on the movable pulley; a support of the fixed pulley is connected with the hydraulic cylinder; and a propping rod is arranged at the front end of the machine frame. The spring balance is arranged, so that the hydraulic expanding and pulling machine can better control pulling force and travel. Furthermore, the hydraulic expanding and pulling machine has the advantages of high work efficiency, simple structure, easy manufacture and convenient use and maintenance.
Description
Technical field
The utility model relates to the machine drawing of rising of a kind of hydraulic pressure that utilizes hydraulic jack to rise to draw quick stretching reinforcing bar.
Background technology
At present, known steel wire rise machine drawing by motor, lead screw pair, and fixed mount form.But because the leading screw stroke is shorter, rotating speed is lower, and maximum pull only reaches 1 ton, can only draw cold rolled reinforcing steel bar with ribs, and operating efficiency is lower, poor accuracy, and pulling force is uncontrollable, and the scope of application is very limited.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of high efficiency is provided, and accuracy is good, the machine drawing of rising of the controlled hydraulic pressure of pulling force.
The utility model is achieved through the following technical solutions:
The machine drawing of rising of a kind of hydraulic pressure, include frame, frame is provided with motor, oil pump, reversing switch, hydraulic cylinder, be connected by oil pipe between oil pump and reversing switch and the hydraulic cylinder, frame lower is provided with roller, the rotating shaft of the motor that is provided with on the frame links to each other with oil pump by shaft coupling, on frame, also be provided with spring scale, one end of spring scale is equipped with steel wire rope, the other end of steel wire rope is fixed on the frame after walking around a movable pulley and a fixed pulley, on the described movable pulley tractor is housed, the support of described fixed pulley links to each other with hydraulic cylinder.
Front end in frame is provided with push rod.
The utility model has the advantages that: the hydraulic pressure steel wire rubbish machine high efficiency that rises, owing to be provided with spring scale, can control pulling force and stroke well, and simple in structure, make easily, use easy to maintenance.
Description of drawings
Figure is a structural representation of the present utility model.
The specific embodiment
Embodiment: the machine drawing of rising of hydraulic pressure as shown in the figure, include frame 6, frame 6 is provided with motor 7, oil pump 15, reversing switch 4, hydraulic cylinder 13, be connected by oil pipe 3 between oil pump 15 and reversing switch 4 and the hydraulic cylinder 13, frame 6 bottoms are provided with roller 2, the rotating shaft of the motor 7 that is provided with on the frame 6 links to each other with oil pump 15 by shaft coupling 5, on frame 6, also be provided with spring scale 14, one end of spring scale 14 is equipped with steel wire rope 12, the other end of steel wire rope 12 is fixed on the frame 6 after walking around a movable pulley 11 and a fixed pulley 9, on the described movable pulley 11 tractor 10 is housed, the support 8 of described fixed pulley 9 links to each other with hydraulic cylinder 13.Front end in frame 6 is provided with push rod 1.
During work, the type of tractive steel wire configures the pulling force of spring scale 14 at first as required, starter motor 7 drives oil pump 15 and starts working, adjusting reversing switch 4 makes the oil in the oil pump 15 enter hydraulic cylinder 13 through oil pipe 3, this moment, hydraulic cylinder 13 was started working, the protruding fixed pulley 9 pulling steel wire ropes 12 that are installed on the hydraulic cylinder 13 that drive simultaneously of hydraulic cylinder 13 cylinder bodies, steel wire rope 12 drives movable pulley 11 makes the steel wire of the tractive of wanting stretching.The stretching back adjustment of steel wire reversing switch 4 retracts hydraulic cylinder 13 cylinder bodies and gets final product.
