Stud is usually comparatively wide in field application such as mining machinery, bridge, automobile, motorcycle, boiler steel structure, large-span steel and heavy constructions, in addition, also quite attractes attention in the high-new industrial circle application such as automobile, aerospace.Double thread is except except machinery production field is indispensable, and it is also quite outstanding in medical field effect, such as, utilize double thread to add nail pressing treatment fracture of neck of femur, its major advantage is that operation technique is easy, fracture fixation is firm, and Wound healing is fast, respond well etc.
The cutting process (i.e. milling, grinding, grinding, tapping etc.) that stud is traditional, production efficiency and machining accuracy all have much room for improvement.
Summary of the invention
In order to overcome the above-mentioned technical problem that the processing of existing stud exists, the object of the invention is to, provide a kind of double threaded screw special screw-rolling machine, structure is simple, and operate steadily, working (machining) efficiency is high, and the deflection of workpiece is little, and machining accuracy is high.
The special screw-rolling machine of double threaded screw provided by the invention, it comprises main shaft, the lathe seat of honour and transmission system, the described lathe seat of honour divides the fixing seat of honour and slip seat of honour two parts, described main shaft is provided with 2, the fixing seat of honour is directly connected with a wherein main shaft, and the slip seat of honour is connected with another main shaft indirectly.Wherein, the slip seat of honour is provided with two oil cylinders, the slip seat of honour, by two oil cylinder pushings, can realize the feeding of process and return.Two oil cylinders by proportional servo closed-loop control, can make the synchro-feed of the slip seat of honour more accurately, more reliable.
Transmission system comprises variable-frequency motor, worm-and-wheel gear, transition gear pair, described worm-and-wheel gear is provided with 2 pairs, 2 secondary worm-and-wheel gears are connected with variable-frequency motor by V belt, it is secondary that 2 secondary worm-and-wheel gears respectively connect a transition gear by universal coupling, 2 secondary transition gear pairs connect 1 main shaft respectively, every root main shaft are all provided with 2 cylindrical die rolls.
The output gear shaft of described transition gear pair is arranged on lathe seat of honour bottom.
The special screw-rolling machine of double threaded screw provided by the invention, its beneficial effect is: under the drive of main shaft and the promotion of oil cylinder, cylindrical die roll does the compound motion of revolution and translation, now, cylindrical die roll is with absorption surface and start to engage, according to the plasticity of metal, cylindrical die roll makes workpiece complete roll forming in the cold state, the screw thread that cold rolling is shaping, its metallic fiber is continuous, fine and closely woven, strengthened in surface, and intensity improves greatly; Adopt frequency control and the worm couple speed change of motor, feed mechanism adoption rate servo closed control, operates steadily, synchronous accurately dependable performance; Main shaft three-point fix on the lathe seat of honour, this structure not only rigidity is better, and machining deformation error is less, and is convenient to install, and two cylindrical die rolls can be installed from main shaft two ends, time saving and energy saving many compared with traditional screw-rolling machine is installed from one end; The maximum magnitude of machining screw is 800mm, and the range of work is comparatively wide, and versatility is comparatively strong, can meet the drift requirement of 6 class precision screw threads; Supporting automatic loading and unloading mechanism, can realize the automation of the synchronous rolling of the two ends same size screw thread of double threaded screw.

Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the special screw-rolling machine of double threaded screw provided by the invention is described in detail.
Embodiment
With reference to Fig. 1, the special screw-rolling machine of double threaded screw of the present embodiment, it comprises main shaft, the lathe seat of honour and transmission system, the described lathe seat of honour divides the fixing seat of honour and the slip seat of honour 4 two parts, described main shaft is provided with 2, the fixing seat of honour 8 is directly connected with a wherein main shaft, and the slip seat of honour 4 is connected with another main shaft indirectly.Wherein, the slip seat of honour 4 is provided with two oil cylinders 5, the slip seat of honour is promoted by two oil cylinders 5, can realize the feeding of process and return.Two oil cylinders 5 by proportional servo closed-loop control, can make the synchro-feed of the slip seat of honour more accurately, more reliable.
Transmission system comprises variable-frequency motor 3, worm-and-wheel gear 2, transition gear pair, described worm-and-wheel gear 2 is provided with 2 pairs, 2 secondary worm-and-wheel gears are arranged in transmission case 1, be connected with variable-frequency motor 3 by V belt, 2 secondary worm-and-wheel gears respectively connect a transition gear pair 6 by universal coupling 9,2 secondary transition gear pairs 6 connect 1 main shaft respectively, every root main shaft are all provided with 2 cylindrical die rolls 7.
The special screw-rolling machine of double threaded screw, variable-frequency motor is through V belt, passing torque to Liang Fu worm-gear-worm mechanism makes it slow down, and then by universal coupling, moment is passed to transition gear pair, two output gear shafts are positioned at seat of honour bottom, avoid the interference of workpiece and gear shaft, transition gear is secondary to be connected with main shaft, so just transmits torque to two main shafts.Two main shafts are equipped with cylindrical die roll, and cylindrical die roll can be driven to do synchronous gyration in the same way.
The special screw-rolling machine of double threaded screw, no matter be labour intensity or production efficiency, everyway increases significantly, especially have in machining accuracy and improve more significantly, this is because double threaded screw special screw-rolling machine processing double thread belongs to cold forming category, its working (machining) efficiency is high, the deflection of workpiece is little, significantly can not only improve workpiece metal tissue and finished surface hardness, and shape later profile of tooth and do not need following process, stock utilization is high.
