Description
Technical field
the utility model relates to a kind of rotary pressing processing field, specifically a kind of spinning processing device of radome abnormal curved surface.
Background technology
metal spinning is a kind of processing technology of metal forming, and this technique can make various rotational symmetric thin-walled revolving mebers and various pipe fittings etc. relatively easily.
necking in spindown utilizes spinner's chisel to make revolving body hollow object or tubular blank carry out radial local rotary compression to reduce the manufacturing process of its diameter.Contracting is threaded through journey and blank is clipped in one heart suitable core (core strictly according to the facts, combination or without core) in, by the outside needing the part be shaped to expose the tool that is installed, when main shaft drives blank to rotate, according to the control mode adopted, make spinning roller reciprocating by the shape track of regulation, make blank necking down step by step, and then obtain swelling-waist shape or close spherical part.
but in necking process, the soft or hard intensity of material is different, causes the profile of workpiece to exist in process and is to a certain degree out of shape, can not meet the dimensional requirement of part.
Summary of the invention
in order to overcome above defect, the utility model provides a kind of spinning processing device of radome abnormal curved surface.This device reliably can ensure the profile that part is processed, and ensures crudy.
the technical solution of the utility model is: a kind of spinning processing device of radome abnormal curved surface, it is characterized in that: be made up of mould, eccentric shaft, eccentric mandrel, eccentric bushing, break bar, taper roll bearing, lubricant reservoir and tail top main shaft, eccentric mandrel periphery is abnormal curved surface, be fixed on mould by straight mouth location, break bar is fixing on the circumferential surface; Lubricant reservoir is fixed in taper roll bearing, and the two ends of taper roll bearing are respectively equipped with dead eye, and dead eye communicates with lubricant reservoir; Taper roll bearing external stability has eccentric bushing, is provided with lubricating oil inlet between lubricant reservoir and eccentric bushing; Eccentric shaft one end is threaded with eccentric mandrel, and the other end penetrates from side dead eye, through lubricant reservoir, is passed by opposite side dead eye, and be threaded connection by tooth abdomen lock nut and be installed on eccentric bushing, eccentric bushing is installed on the main shaft of tail top by holding screw.
same area abnormal curved surface consistent size inside the utility model eccentric mandrel abnormal curved surface and part, and according to the eccentric mandrel of the different shaped face of the part exchanging of different profile.
lubricating oil inlet described in the utility model is provided with plug.
same area abnormal curved surface consistent size inside the utility model eccentric mandrel abnormal curved surface and part, and eccentric mandrel that can be different according to the part exchanging of different profile.Workpiece is close to eccentric mandrel in break bar spinning process, reliably ensures the profile of workpiece, meets its dimensional requirement.
the beneficial effects of the utility model are: the utility model eccentric mandrel is driven by eccentric shaft, and working stability is reliable, and break bar can be made to process stable workpiece configurations; The utility model highly versatile, can need to change according to difference, workable, meets the dimensional requirement of workpiece.
Accompanying drawing explanation
fig. 1 is the spinning processing device structural representation of a kind of radome abnormal curved surface of the utility model.
Detailed description of the invention
as shown in Figure 1, a kind of spinning processing device of radome abnormal curved surface, it is characterized in that: be made up of mould 1, eccentric shaft 3, eccentric mandrel 2, eccentric bushing 6, break bar 4, taper roll bearing 9, lubricant reservoir 7 and tail top main shaft 11, eccentric mandrel 2 periphery is abnormal curved surface, be fixed on mould 1 by straight mouth location, break bar 4 is fixing on the circumferential surface; Lubricant reservoir 7 is fixed in taper roll bearing 9, and the two ends of taper roll bearing 9 are respectively equipped with dead eye, and dead eye communicates with lubricant reservoir 7; Taper roll bearing 9 external stability has eccentric bushing 6, is provided with lubricating oil inlet between lubricant reservoir 7 and eccentric bushing 6; Eccentric shaft 3 one end is threaded with eccentric mandrel 2, the other end penetrates from side dead eye, through lubricant reservoir 7, is passed by opposite side dead eye, being threaded connection by tooth abdomen lock nut 10 is installed on eccentric bushing 6, and eccentric bushing 6 is installed on tail top main shaft 11 by holding screw.
same area abnormal curved surface consistent size inside the utility model eccentric mandrel 2 abnormal curved surface and part, and according to the eccentric mandrel of the different shaped face of the part exchanging of different profile.
lubricating oil inlet described in the utility model is provided with plug.
same area abnormal curved surface consistent size inside the utility model eccentric mandrel abnormal curved surface and part, and eccentric mandrel that can be different according to the part exchanging of different profile, workpiece is close to eccentric mandrel in break bar spinning process, reliably ensures the profile of workpiece, meets its dimensional requirement.
