The utility model content
The purpose of this utility model provides the high hot spinning closing in machine of a kind of production efficiency.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of hot spinning closing in machine, the rear end of lathe bed is provided with the material feed clamping device, in the place ahead of lathe bed mainshaft mechanism is installed, and in the place ahead of mainshaft mechanism die device and frequency heating device is arranged.
Heat patching device and spinning roller device are arranged on the described die device.
Described heater is a frequency heating device.
The utility model is when the loading and unloading of gas cylinder, adopt the material feed clamping device on lathe bed and the lathe bed, improved production efficiency like this, in addition, the place ahead at mainshaft mechanism is provided with die device, by die device the bottle head is closed up, and not only enhances productivity, and reduced the staff, reduced production cost.
The beneficial effects of the utility model are: improved production efficiency more than 1 times 1.; 2. reduce operation, reduced the support staff, reduced non-cutting time; 3. improved the service time of mould, service life is greater than 1000 bottle heads; 4. can realize Automatic Control.
The specific embodiment
The structure of a kind of hot spinning closing in of the utility model machine as shown in Figure 1 and Figure 2, the rear end of lathe bed 1 is provided with material feed clamping device 2, in the place ahead of lathe bed 1 mainshaft mechanism 3 is installed, and die device 5 and frequency heating device 4 are arranged in the place ahead of mainshaft mechanism 3.Heat patching device and spinning roller device are arranged on the described die device 5.
The utility model mainly is made up of heater, heat patching device, die device, mainshaft mechanism, material feed clamping device, electric-control system, hydraulic pressure and pneumatic system, lubricating system etc.
The function of heater is before bottle base is closed up, and utilizes the Frequency Induction Heating principle, bottle base is carried out online heating, so that the closing in moulding.Heater is the dolly form, moves within the specific limits, and replaceable its load coil is to adapt to the gas cylinder of different size.
Heat patching device is two heating blowpipees that are fixed on the die device, and its function is after heating in medium frequency, when mould carries out spinning closing-in to bottle base, bottle base is heated, to keep the needed temperature of spinning.It adopts flame heat, can regulate the relative position and the angle of heating blowpipe and bottle base, to reach best concurrent heating effect, cooling water channel is arranged in the heating blowpipe, external Pressure gauge, and high-voltage pulse is lighted a fire automatically, and flameholding is safe and reliable.
The function of die device is to bottle base closing in moulding.The forming principle of die device is: the spinning roller device is the center of circle with the point on the bottle base axis, carry out rotatablely moving of set angle, every rotation once, mould shaft is to cylinder displacement, make mould move certain distance vertically backward, when making mould rotation next time, start position is different, so also just formed directions X (radially), the compound motion of Y direction (axially), repeatedly such motion, thereby gradually bottle base is closed up into dome-type, in the spinning roller rotation, do spinning motion again passively, spinning roller is rolling friction with the friction between the workpiece like this.Be provided with rotary encoder on the mould rotating shaft, more according to the performance of its feedback, the passing ratio flow speed control valve is controlled speed and direction and angle that mould rotates to hydraulic system.Mould moves axially and adopts the displacement cylinder, and hydraulic system is according to the displacement transducer feedack of oil cylinder afterbody, and the passing ratio flow speed control valve is controlled the displacement of oil cylinder, and its positioning accuracy height has good impact resistance.Roller is radially advanced and retreat, so that the conversion of the work step of heating in medium frequency and rotary press modelling.Rail plate is all adopted in moving radially and moving axially of mould, and the guide rail exposed parts adopts the protection of extension type corrosion resistant plate protective cover.Guide rail is equipped with the auto lube pumping plant, and is timing automatic lubricated.
The function of mainshaft mechanism is to clamp and provide torque to bottle base.Dustproof, the waterproof of main spindle box employing enclosed construction.Main shaft drives adopts DC motor speed-regulating mode, gear drive.Main shaft is a hollow-core construction.Adopt the big cornerite chuck of hydraulic pressure five pawls, adopt external twin-tub pulling to clamp, claw is vertical feed radially, changes minority tool part such as claw, can adapt to different specification products.The driving oil cylinder of chuck is arranged in the rear end of equipment.Main shaft bearing adopts the homemade bearing of high-quality, and the bearing of main spindle box and gear adopt the thin oil circulating lubricating mode of forcing, and lubricating oil is used the water recirculator cooling, and remain on below 45 ℃.
The effect of material feed clamping device is the loading and unloading of being responsible for bottle base, and when bottle base closes up, and the afterbody of gas cylinder is played support and clamping action.It is identical with mainshaft mechanism that it clamps principle.Travel mechanism is made up of the reducing motor of slide rail, tooth bar, gear and band brake, the electronic tailstock of similar heavy-duty engine lathe.Tailstock drives bottle base and moves, thereby realizes the loading and unloading to bottle base.The lubricated of slide rail is the automatic drip-feed lubricating of thin oil, and the bearing of main spindle box adopts forces thin oil circulating lubricating, lubricating oil is used the water recirculator cooling, and remain on below 45 ℃.The utility model adopts back charging, the mode of back discharging.
