Description
Background technology
This technology relates to the surface of the work calendering device improving workpiece surface finish.
Background technology
At present, for the calendering techniques comparative maturity of plane, cylinder or sphere, and for the surperficial press polish of the spiral camber workpiece of complexity or a difficult problem, be mainly manifested in that working (machining) efficiency is low, press polish poor quality, even have no idea to carry out press polish processing.In order to provide the fineness of surface of the work, utilize extrusion head to apply for a long time the technology that surface of the work carries out press polish, but will to having that complex-curved workpiece carries out efficiently, high speed press polish processing, yet there are no report.
Summary of the invention
The object of this technology is to provide a kind of extrusion head and rotates around Work piece high-speed, the surface of the work calendering device that workpiece rotates at a slow speed, and it is especially applicable to the press polish processing of multiple-threaded screw surface.
Surface of the work calendering device described in this technology, it comprises support, main axis is arranged on support, and main shaft arranges oil cylinder, and the piston rod of oil cylinder is connected with extrusion head; The hydraulic channel of oil cylinder communicates with the oil feed line in main shaft; Be surrounded with the oil ring be fixed on support in main shaft periphery, there is in oil ring the oil inlet passage communicated with oil feed line; The hydraulic oil interface being arranged on oil ring periphery communicates with oil supply system; Oil supply system passes through hydraulic oil interface, oil inlet passage, oil feed line to oil cylinder fuel feeding.
The beneficial effect of this technology: when oil supply system passes through hydraulic oil interface, oil inlet passage, oil feed line to oil cylinder fuel feeding, the piston rod of oil cylinder drives extrusion head to be pressed on the surface of workpiece.Main axis, extrusion head is just with main axis, and extrusion head completes rolling and processing to Workpiece periphery.This technology, the combination of the cyclone technology of rolling techniques and main shaft High Rotation Speed, is reprocessed the surface of workpiece, is improve the surface roughness of workpiece, meanwhile, utilize the high efficiency of whirlwind process technology, improves the working (machining) efficiency of roll extrusion workpiece.Meanwhile, because extrusion head is pressed on surface of the work under the effect of cylinder piston rod, the pressure of oil cylinder can adjust arbitrarily as required, stronger to the adaptability of workpiece.In addition, compared to mechanical stitch system, this device has certain flexibility, not fragile.
Above-mentioned surface of the work calendering device, in the annular seal space that oil ring is formed between main shaft periphery two ends and support, the bottom of annular seal space communicates with the oil return interface be arranged on support; Hydraulic oil interface is arranged on support.The hydraulic oil leaked can be derived by oil return interface.
Above-mentioned surface of the work calendering device, respectively have one in the both sides of annular oil inlet passage around the drainback passage of the annular of main shaft periphery, drainback passage communicates with annular seal space in oil ring around the oil inlet passage of main shaft periphery ringwise.At the drainback passage of the annular of oil inlet passage both sides, to prevent in oil inlet passage hydraulic oil in the leakage of axis.
Above-mentioned surface of the work calendering device, main shaft is arranged on support by the bearing rotation that two are positioned at annular seal space, and support is arranged through the motor that belt transmission drive shaft is rotated.In annular seal space, hydraulic oil can lubricate bearing.Support arranges motor, and is rotated by belt transmission drive shaft, compact overall structure, volume is little.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of surface of the work calendering device;
Fig. 2 is the schematic diagram that oil cylinder communicates with the oil inlet passage of in oil ring;
Fig. 3 is the schematic diagram that oil cylinder communicates with another oil inlet passage in oil ring.
Detailed description of the invention
See the surface of the work calendering device shown in Fig. 1-3, in the annular seal space formed between hollow two ends, main shaft 1 periphery and support 38, main shaft 1 is arranged on support 3 by bearing 2 rotation that two are positioned at annular seal space, and support is arranged through the motor 22 that belt 21 transmission drive shaft is rotated.
An end face of main shaft arranges oil cylinder 5, and the piston rod end of oil cylinder 5 connects extrusion head 6.Extrusion head 6 can be the common extrusion head of the ball with rolling, also can be person of outstanding talent's gram energy cutter (extrusion head).Person of outstanding talent gram can be utilize the energy composite energy of activation energy and impact energy to process metal parts, and time processing can make piece surface reach minute surface and realize the novelty energy process technology of modification.Person of outstanding talent's gram energy metal surface mirror finish, after workpiece size be worked into substantially put in place with universal cutter, use person of outstanding talent's gram energy cutter (extrusion head) to surface of the work extrusion process again, workpiece to be machined surface smoothness can be made to improve more than 3 grades (roughness Ra value easily reaches less than 0.2); And the surface microhardness of workpiece improves more than 20%; And substantially increase surface abrasion resistance and the corrosion resistance of workpiece.
Two oil feed lines 11,12 in the hydraulic channel of oil cylinder and main shaft are in parallel.Be surrounded with in main shaft periphery and be fixed on oil ring 7 on support, that be positioned at annular seal space, there is in oil ring the oil inlet passage 71,72 around main shaft periphery communicated respectively with oil feed line 11,12; Two are had around the drainback passage 73,74 of main shaft periphery in the both sides of annular oil inlet passage 71,72.Drainback passage 73,74 communicates with annular seal space.The drainback passage intercommunicating pore 31 being positioned at support is communicated with drainback passage 73,74.The bottom of annular seal space communicates with the oil return interface 10 be arranged on support; Two the hydraulic oil interfaces 91,92 be arranged on support communicate with oil inlet passage 71,72 respectively.
Two hydraulic oil interfaces communicate with oil supply system; When oil supply system by hydraulic oil interface, oil inlet passage, oil feed line to the hydraulic channel fuel feeding of oil cylinder, extrusion head contacts under the effect of cylinder piston rod with the periphery of processed workpiece 23.
This patent utilizes the combination of rolling techniques and cyclone technology, replaces Whirlwind milling cutter, carry out roll extrusion again, improve the surface roughness of workpiece, meanwhile, utilize the high efficiency of whirlwind process technology to the surface of workpiece with extrusion head, improves the efficiency of roll extrusion workpiece.
