Description
Technical field
The present invention relates to a kind of spinning head rotation, material folding of spinning machine, the control oil circuit of discharging device.
Background technology
Numerical control closed loop spoke spinning machine is mainly used in automobile spoke spinning, moulding.The spoke of mould pressing has not advantages such as uniform thickness, equal strength, good looking appearance; Can be applicable to the inner tube of a tyre and the different demands of tubeless wheel rim widely to spoke.Spoke spinning is a kind of composite spinning, and it has powerful extruding to revolve thin characteristics again to the characteristics of dull and stereotyped (automobile spoke steel plate special) existing conventional spinning.
At present, abroad the control device of this kind spinning machine mainly adopts hydraulic circuit is controlled, and by the control to oil pressure, oil mass, realizes the displacement control of spinning head device.This mode has high requirement to the precision of parts in hydraulic oil degree of purity, the hydraulic circuit and the environment for use of equipment, the processing environment of similar devices is difficult to reach above-mentioned requirements mostly, simultaneously the use cost of the hydraulic oil of high cleanliness, high-precision hydraulic components is high, takes this kind mode control appliance can cause that equipment cost is extremely expensive, use cost is high.Simultaneously, compare with hydraulic circuits such as spinning head rotation, material folding, the materials returned, need the requirement that oil pressure is higher, needs are adjusted control in real time higher in view of the spinning head feeding drives oil circuit, therefore, include above-mentioned everything in a hydraulic control oil circuit, cause power redundancy on the contrary, consumes energy.
Summary of the invention
The present invention is directed to above problem, provide a kind of classification, blockette to realize hydraulic control, thus can be more economically, spinning head rotation, material folding, the control oil circuit of discharging device of spinning machine easily.
Technical scheme of the present invention is: described spinning machine comprises that the hydraulic motor, pressure plate cylinder, the material returned that drive left and right sides spinning head eject oil cylinder and hydraulic power source, hydraulic power source is provided with output circuit No. one, No. two, it also comprises the hydraulic motor control loop, is used to control the electro-hydraulic reversing valve two of pressure plate cylinder, is used to control the electromagnetic relief valve one that the material returned ejects the electro-hydraulic reversing valve one of oil cylinder and is used to control an oil circuit pressure, and electro-hydraulic reversing valve two, electro-hydraulic reversing valve one and electromagnetic relief valve one link to each other with an output circuit of hydraulic power source respectively; The hydraulic motor control loop comprises the electromagnetic relief valve two and the overflow valve of mutual serial connection, and electromagnetic relief valve two connects No. two output circuits.
Hydraulic circuit of the present invention is primarily aimed at the low relatively several hydraulic operation spares of spinning machine upward pressure requirement and establishes, and has so just avoided having loaded in the hydraulic system power redundancy that causes, the phenomenon of energy waste.And for the feed cylinder, the required precision of several actions that the present invention will realize is relatively low with respect to the X, the Z that realize cold-pressing deformation processing, relatively also can reduce the requirement of the hydraulic part in the oil circuit, can save cost greatly.
