Summary of the invention
The object of the present invention is to provide a kind of hydraulic forming equipment that has the propulsion system that control is convenient, precision is high.
For achieving the above object, the technical solution used in the present invention is:
A kind of hydraulic forming equipment, comprise the workbench that is used to lay workpiece, be used for the fixture that workpiece is fixing, be arranged on the push system of workbench both sides, push system comprises to small part and stretches into extruding work package in workpiece lumen, it is characterized in that: push system also comprises motor, is used for the kinetic energy of motor is delivered to the propulsion assembly that pushes on the work package, propulsion assembly comprises first connector and second connector that is in transmission connection mutually, first connector is in transmission connection mutually with the output shaft of motor, and second connector is fixedly connected with the extruding work package.
First connector is a screw rod, and second connector is a nut, and first connector is connected with the second connector threaded engagement.Identical, first connector is a nut, second connector is a screw rod, and first connector is connected with the second connector threaded engagement.
The output of motor also is connected with deceleration device, and the output of first connector and deceleration device is fixedly connected.Motor is a servomotor.
Fixture comprises that a main cylinder pressure, one are arranged on the last shaping mould of main cylinder pressure below, a liftout cylinder that is positioned at below the workbench, have the compacted under mould relative with last shaping mould on the workbench.
Because the employing of technique scheme, the present invention compared with prior art has the following advantages:
Design and manufacture a kind of shaped by fluid pressure setting different, and reached identical technique effect with conventional art;
Owing to used by motor and the combined mode of propulsion assembly to promote to push work package, reduced production cost;
The combination of adopting nut and screw rod is as propulsive mechanism, when motor quits work, can self-locking, and be embodied on the extruding work package, be, when motor stops operating, extruding work package and the not minimizing of pressure that is extruded between the part;
Motor adopts servomotor, has reached the accurate purpose of control, has reached the technique effect that is equal to mature technique.
