Abstract
The utility model discloses a machine head oil pressure raising device of a full-automatic pipe bender, which has comparatively low manufacturing cost and comprises a jacking oil cylinder fixedly arranged on a machine body. A piston rod of the jacking oil cylinder is connected with the lower end of a machine head, the lower end of the jacking oil cylinder is connected with a first connecting pipe, the other end of the first connecting pipe is connected with one end of an oil tank through a second connecting pipe, an overflow valve is disposed on the second connecting pipe, the other end of the first connecting pipe is connected with an oil pump via a third connecting pipe, a pressure gauge, a check valve, a reducing valve and an electromagnetic valve are sequentially arranged on the third connecting pipe, and the oil pump is connected with the other end of the oil tank via a fourth connecting pipe. The raising device has the advantages that the full-automatic pipe bender provided with the machine head oil pressure raising device has comparatively low manufacturing cost, and is capable of realizing up and down movement of the machine head, enabling the machine head to be positioned more accurately, ensuring ball screws not to bear comparatively large pressure, preventing the ball screws from torsion and damage, and prolonging the service life of the ball screws.
Description
Technical field
The utility model relates to a kind of fully-automatic bent-pipe machine, relates in particular to head oil pressure picking-up device in a kind of fully-automatic bent-pipe machine.
Background technology
The head of existing fully-automatic bent-pipe machine moves up and down, mainly be to drive ball-screw by servomotor and the reductor that is arranged on the head, thereby realize that head moves up and down, in practical work process, need to change the wheel mould number on the head, the weight of head is strengthened, cause ball-screw to bear bigger pressure, the ball-screw distortion is damaged, therefore, in order to hold up heavier head, need to change powerful servomotor, will increase manufacturing cost greatly like this, the speed that head moves up and down is also very slow, and accuracy can not get guaranteeing.
The utility model content
Technical problem to be solved in the utility model is: head oil pressure picking-up device in the lower fully-automatic bent-pipe machine of a kind of manufacturing cost is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: head oil pressure picking-up device in the fully-automatic bent-pipe machine, comprise: be fixedly installed on the jacking cylinder on the fuselage, the piston rod of jacking cylinder is connected with the lower end of head, the lower end of jacking cylinder is connected with first tube connector, the other end of first tube connector is connected with an end of fuel tank by second tube connector, second tube connector is provided with overflow valve, the other end of first tube connector is connected with oil pump by the 3rd tube connector, on the 3rd tube connector, be disposed with Pressure gauge, check valve, pressure-reducing valve and magnetic valve, oil pump is connected with the other end of fuel tank by the 4th tube connector.
The utility model has the advantages that: the fully-automatic bent-pipe machine that said structure head oil pressure picking-up device is housed, manufacturing cost is lower, can realize fast that head moves up and down, make the head location more accurate, guarantee that ball-screw does not bear bigger pressure, prevent that the ball-screw distortion from damaging, and prolonged the service life of ball-screw.
Description of drawings
Fig. 1 is the structural representation when head oil pressure picking-up device uses in the utility model fully-automatic bent-pipe machine.
Among the figure: 1, lathe bed, 2, jacking cylinder, 3, piston rod, 4, head, 5, first tube connector, 6, second tube connector, 7, fuel tank, 8, overflow valve, the 9, the 3rd tube connector, 10, oil pump, 11, Pressure gauge, 12, check valve, 13, pressure-reducing valve, 14, magnetic valve, the 15, the 4th tube connector, 16, servomotor, 17, reductor, 18, ball-screw.
The specific embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, head oil pressure picking-up device in the fully-automatic bent-pipe machine, comprise: be fixedly installed on the jacking cylinder 2 on the fuselage 1, the piston rod 3 of jacking cylinder 2 is connected with the lower end of head 4, the lower end of jacking cylinder 2 is connected with first tube connector 5, the other end of first tube connector 5 is connected with an end of fuel tank 7 by second tube connector 6, second tube connector 6 is provided with overflow valve 8, the other end of first tube connector 5 is connected with oil pump 10 by the 3rd tube connector 9, on the 3rd tube connector 9, be disposed with Pressure gauge 11, check valve 12, pressure-reducing valve 13 and magnetic valve 14, oil pump 10 is connected with the other end of fuel tank 7 by the 4th tube connector 15.
When the head 4 of fully-automatic bent-pipe machine need move upward, open magnetic valve 14, start oil pump 10, oil pump 10 is extracted pressure oil out from fuel tank 7 by the 4th tube connector 15, pressure oil enters into jacking cylinder 2 lower ends after reducing pressure through pressure-reducing valve 13, thereby the head 4 that promotion piston rod 3 is connected with piston rod 3 travels forward together, and the head 4 that is connected with piston rod 3 is played upwards picking-up effect.Be arranged on servomotor 16 on the head 4 by control then, servomotor 16 drives reductors 17 and the ball-screw 18 that is connected with reductor 17 rotates, thereby realizes moving up and down of head 4.In practical work process, overflow valve 8 can play the effect that steady pressure prevents the air pressure shakiness; Check valve 12 can prevent the effect that head 4 falls under the situation that fuel feeding goes wrong; Pressure gauge 11 can be observed intrasystem oil pressure situation better.
When the head 4 of fully-automatic bent-pipe machine need move downward, in the piston rod 3 withdrawal jacking cylinders 2, the pressure oil in the jacking cylinder 2 entered into second tube connector 6 from first tube connector 5, flow back in the fuel tank 7 through overflow valve 8.The fully-automatic bent-pipe machine of said structure head oil pressure picking-up device is housed, manufacturing cost is lower, can realize fast that head 4 moves up and down, make head 4 location more accurate, guarantee that ball-screw 18 does not bear bigger pressure, prevent that ball-screw 18 distortions from damaging, and prolonged the service life of ball-screw 18.
