Description
Technical field
The utility model relates to hydraulic test manufacturing technology field, relates in particular to a kind of machine liquid radial forging.
Background technology
The forging machine of prior art mainly contains two kinds, i.e. mechanical type forging machine and all-hydraulic control formula forging machine, and the speed of mechanical type forging machine is uncontrollable, hydraulic shock and heating that all-hydraulic control formula forging machine easily causes at fast large flow and while commutating fast.Development and manufacturing prosperity along with national economy, the demand of each forging increases rapidly, the quality requirement of section part is also more and more higher, forging ' s block dimension precision is also more and more higher, requires accordingly forging machine day by day to mechanical type forging machine and the all-hydraulic control formula forging machine of precise treatment, specialization, high efficiency development so prior art, can not meet the needs of forging industry.
Summary of the invention
The purpose of this utility model is the defect for above-mentioned prior art, and a kind of machine liquid radial forging is provided, and control system is simple, and speed is controlled, hydraulic shock and the fever phenomenon avoiding the fast large flow of all-hydraulic control formula forging machine and commutate and cause fast.
To achieve these goals, the technical solution of the utility model is:
A kind of machine liquid radial forging, the frame that comprises forging machine, described frame is radially oppositely arranged four oil pressure cylinders, described oil pressure cylinder is divided into rod chamber and rodless cavity, the rod chamber of described oil pressure cylinder is all communicated with source of the gas by reversal valve, the rodless cavity of described oil pressure cylinder is pressure oil cavity, by pipeline, distinguish external for the topping up cylinder of oil pressure cylinder topping up, described topping up cylinder is single-action hydraulic cylinder, be divided into rod chamber and rodless cavity, the rod chamber of described topping up cylinder communicates with outside atmosphere, and the rodless cavity of described topping up cylinder is connected with the rodless cavity of oil pressure cylinder; The piston rod of described topping up cylinder connects cam drive outward.
Further, described cam drive is in transmission connection by belt gear, described belt gear, comprise a big belt pulley, belt, small belt pulley, described big belt pulley is arranged on cam drive, described small belt pulley is arranged on the output shaft of speed changer, and described speed changer is connected with motor-driven by shaft coupling.
Further, described motor is servomotor, and described servomotor is external is used for controlling the computer that motor carries out stepless automatic transmission.
Further, the external feed circuit of the rodless cavity of described topping up cylinder.
Further, described reversal valve is electromagnetism gas control two-position four way change valve.
Compared with prior art, the beneficial effects of the utility model are:
Machine liquid radial forging of the present utility model, servomotor, by shaft coupling, reductor, belt gear, cam drive, is transformed into rotatablely moving of servomotor the linear telescopic motion of topping up cylinder piston rod.Topping up cylinder piston rod shrinks, and the pressure oil of topping up cylinder rodless cavity is depressed into the back cavity of the oil pressure cylinder being connected respectively with it, and oil pressure cylinder piston rod is stretched out, and center workpiece is suppressed, and the rod chamber of oil pressure cylinder is exhaust condition simultaneously; As the motion of cam drive makes topping up cylinder piston rod, stretch out, and the rod chamber of oil pressure cylinder is atmospheric pressure state simultaneously, the piston rod of oil pressure cylinder is retracted, and completes once compacting, has the feed circuit of a small displacement between topping up cylinder and oil pressure cylinder.
Servomotor, reductor, belt transmission, cam drive are mechanical rotatablely moving, and are hydraulic drive between topping up cylinder and oil pressure cylinder, and Pneumatic Transmission is leaned in the retraction of oil pressure cylinder,
Servomotor can be connected with computer, realizes the stepless automatic control of speed, then by the control to solenoid directional control valve, can realize the flexible speed of oil pressure cylinder and commutating frequency are controlled, thus radially relatively suppressing and controlling forcing press.
The machine liquid radial forging of this version is particularly suitable for the rapid forge of the solid or hollow longaxones parts of small dimension, control system is simple, has avoided fast large flow and quick hydraulic shock and the fever phenomenon that commutates and cause of the uncontrollable and all-hydraulic control formula of speed of mechanical type press.
