Description
Technical field
The utility model is related to the spinning roller device to a kind of spinning machine, especially realize in spinning process squeeze workpiece at
Type.
Background technology
Spinning roller is the main forming tool of rotary pressing processing, and the spinning roller of general spinning machine is non-driven type at present, no drive
Dynamic, spinning roller is rotated by its contact friction force drive workpiece between when work；Or more high-end spinning machine driving
Servo motor driving is mostly used, but since servo motor structure limits, causes servo motor volume itself excessive, is mounted on rotation
On wheel body, it will also result in that spinning roller device overall volume is excessive, and in spinning small diameter workpiece, spinning roller or spinning roller holder have each other
It may collide, if but in order not to make to collide, need to suitably reduce the method for spinning roller diameter and spinning roller holder outer profile size
It solves, certainly, can accordingly reduce main shaft and bearing size in this way, cause to weaken its bearing capacity.
Invention content
The purpose of this utility model is while to provide one kind to realize the included rotating function of prewhirling that can be synchronous with workpiece of spinning roller
Compact-sized spinning roller device.
The technical solution adopted in the utility model is：Torque motor stator is mounted on spinning roller body, and rotor is fixed on master
On axis, driving spindle rotation is run by torque motor；Encoder is mounted on main shaft tail, feeds back the speed of mainshaft；On main shaft
Bearing is installed and bears spinning radial load and axial load.
Spinning roller device described in the utility model, composition includes torque motor, main shaft, rotary encoder, bearing (cylinder
Roller bearing, self-aligning thrust roller bearing, double-row self-aligning roller bearing), spinning roller body, spinning roller, spinning roller holder.Band rotary encoder
Torque motor be mounted on main shaft tail end；The torque motor stator is mounted on spinning roller body, and rotor is connect with main shaft, is passed through
Torque motor runs driving spindle rotation；Double-row self-aligning roller bearing and cylindrical roller are installed respectively in the tail end of main shaft and front end
Bearing bears spinning radial load, installs two self-aligning thrust roller bearings at the middle part of main shaft, bears spinning axial load；
Meanwhile workpiece shaping is squeezed in front-end of spindle installation spinning wheel, feed back spinning roller rotating speed in main shaft tail end installation rotary encoder.With
Upper each device is mounted in spinning roller body, and spinning roller body and spinning roller holder are linked together by bolt, nut etc..
The principle of spinning roller device described in the utility model is：By torque motor driving spindle, pass through rotary encoder
The speed of mainshaft, the axial load generated when bearing spinning roller workpiece by bearing and radial load are fed back, spinning roller is driven by main shaft
Spinning roller body, is connect by rotation by bolt and nut with spinning roller holder.
Since the torque motor with rotary encoder is mounted on main shaft tail end, meet spinning roller before spinning by torque motor band
Pre-rotation dynamic and that work is synchronous with workpiece moves, to not generate the shock occurred by speed difference when spinning roller and workpiece being made to contact
Phenomenon does not damage workpiece surface, while can make again compact-sized, can meet flow formed part diameter range requirement to greatest extent.
Through examining, using spinning roller device described in the utility model, applies on numerical control strong spinning machine, can meet to institute
The requirement for needing the mould pressing of part to work.
