Abstract
Provided is a lifting and inclination driving system of a forging manipulator. A lifting direction valve is connected with an oil supply port and an oil return port and is connected with a left rear lifting cylinder large cavity and a right rear lifting cylinder large cavity, an inclined direction valve is connected with the oil supply port, the oil return port, a left front lifting cylinder and a right front lifting cylinder, an inclined overflow valve is connected with the oil return port, the left front lifting cylinder (7) and the right front lifting cylinder (7), and a lifting overflow valve is connected with the oil return port, the left rear lifting cylinder large cavity and the right rear lifting cylinder large cavity. The lifting and inclination driving system of the forging manipulator solves the problem brought by poor synchronicity of four independent control oil cylinders in a lifting and inclination driving system of the forging manipulator in the prior art, and the loop has the advantages of being simple in structure, high in control precision and high in reliability.
Description
Technical field
The present invention relates to flat-die forging equipment technology field, particularly relate to a kind of forging manipulator lifting pitch drives system.
Background technology
Forging manipulator is one of indispensable important equipment in the middle of automatic forging operation, is enhancing productivity, and ensures that the aspects such as crudy play an important role.The action that forging manipulator has needed comprises jaw clamping and release, the forward and reverse rotation of claw beam, and lifting is tilted, sidesway side-sway, cart forward-reverse.Prior art often adopts all around that four lift cylinders are to complete lifting and the tilting action of claw beam, and four oil cylinders are independent control, and synchronism is bad, and easily cause in lifting tilting procedure stuck, action control precision is low, and control system is complicated.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of the present invention is to provide a kind of forging manipulator to be elevated pitch drives system, there is simple for structure, that control accuracy is high, reliability is high feature.
In order to achieve the above object, technical scheme of the present invention is:
A kind of forging manipulator lifting pitch drives system, comprise lifting direction valve 4, the P mouth of lifting direction valve 4 is connected with oil-feed port 1, and the T mouth of lifting direction valve 4 is connected with oil return opening 2, and the A mouth of lifting direction valve 4 is connected with left back lift cylinders large chamber 9-1 and the large chamber 10-1 of right back lift cylinders; The P mouth of incline direction valve 3 is connected with oil-feed port 1, and the T mouth of incline direction valve 3 is connected with oil return opening 2, and the A mouth of incline direction valve 3 is connected with left front lift cylinders 7 and right front lift cylinders 8; The P mouth of inclination overflow valve 5 is connected with left front lift cylinders 7 and right front lift cylinders 8, and the T mouth of inclination overflow valve 5 is connected with oil return opening 2; The P mouth of lifting overflow valve 6 is connected with left back lift cylinders large chamber 9-1 and the large chamber 10-1 of right back lift cylinders, and the T mouth of lifting overflow valve 6 is connected with oil return opening 2.
Left front lift cylinders 7, right front lift cylinders 8, left back lift cylinders ring cavity 9-2 is with right back lift cylinders ring cavity 10-2 area equation and be communicated with, and left back lift cylinders large chamber 9-1 is with right back lift cylinders large chamber 10-1 area equation and be communicated with.
The beneficial effect that the present invention has is:
Four independent problems controlling oil cylinder poor synchronization and bring in a kind of forging manipulator lifting pitch drives system of prior art can be solved; This loop has simple for structure, and control accuracy is high, the feature that reliability is high.
