Description
Technical field
The present invention relates to a kind of spinning roller closing device, particularly the assembling of a kind of spinning roller of spinning roller closing device and spinning roller axle.
Background technology
It is the visual plant that the CNG gas cylinder is produced that the TWH425 spinning roller is received end closing-up machine, and digital control system control hydraulic drive spinning roller press the track operation, product is carried out heat fusion process and close up or receive the end.Its spinning roller assembling, operating position directly affect product quality and product percent of pass.
The operation principle that adopts spinning roller to close up is: the steel billet through material conveying mechanism heats or not heating is delivered in the turn-down rig V-type groove, the action of stirring cylinder advance put in place after, the clamping walking mechanism clamps steel billet and delivers in the main shaft chuck.The discharging cylinder is in retracted position, and the steel billet top is by discharging cylinder discharging location.The clamping cylinder action makes the clamping bottle base of chuck, the input and output material cylinder is return original position, motor drives main shaft and steel billet rotation by belt, die cylinder rotates mould and steel billet is closed up or receipts end moulding, mould is return original position, clamping cylinder unclamps jaw, and drawing mechanism is released main shaft in turn-down rig V-type groove with the pipe of moulding, and the stirring cylinder action is routed up steel billet.
Existing spinning roller is to adopt 12 M14*75 high-strength hexagon socket-head bolts to be connected with spinning roller axle connected mode, and its defective is as follows:
1, because spinning roller with spinning roller axle mating surface precision is high, spinning roller heavy (approximately 100kg), connects with 12 bolts, assemble difficult.
2, spinning roller in the course of the work, the very large and high temperature of spinning roller and product extruding force, bolt is yielding under Tensile and twisting action power, elongation, spinning roller and spinning roller axle are easily loosening, work a period of time is broken, and be difficult to take out by the bolt broken, also need use in case of necessity electric drill, the screwed hole on the spinning roller axle also must tapping etc. series of problems.
3, former spinning roller and spinning roller axle are connected to that the 12-M14*75 high-strength hexagon socket-head bolt is connected, the spinning roller pilot hole is of a size of ￠ 140H7, spinning roller axle assembling spinning roller place is that ￠ 140k6 belongs to interference fits, it has only guaranteed that spinning roller and spinning roller axle reach the assembly technology requirement, mainly by the link of 12-M14*75 high-strength hexagon socket-head bolt.Product processing since spinning roller edge ￠ 500 arc surface places be product processing work point, its extruding force is very large, suffered force direction is 45 degree circular arc tangential line directions, cause bolt to be subjected to that pulling force produces deformation (reason of expanding with heat and contract with cold in addition), spinning roller often becomes flexible with beam warp and be difficult for discovering, cause converted products defective, and repair, the refitting workload is large, affect production efficiency, refitting causes often spinning roller and the assembling of spinning roller axle not to reach requirement and scraps, and causes unnecessary loss (changing 1.1 ten thousand yuan of spinning rollers, 0.8 ten thousand yuan on axle).
The connectivity problem that solves spinning roller and spinning roller axle becomes and improves the major issue that the TWH425 spinning roller is received end closing-up machine utilization rate of equipment and installations and product quality.
Summary of the invention
