During spinning, being fixed to by the blank of plate blank or molding in advance on the core of rotation, with spinning roller, blank is applied pressure, spinning roller is made axial feeding simultaneously, is processed through one or many, obtain the process of various thin-walled hollow revolving body goods.Have manually and automatically point, have conventional spinning and shear spinning point, the plastic materials such as copper-iron-aluminium rustless steel titanium alloy can be done.The contact area of spinning roller and blank is the least, and rapidoprint only locally occurs plastic deformation, and resistance of deformation is little, can use the goods that the apparatus processing of little tonnage is large-scale, is the effective ways manufacturing the precise products such as conulite, cylindrical member, hemisphere and thin-wall pipes.
But, the shortcoming that presently, there are is that the shape of product produced is restricted, and the shape of product is mainly determined by core, but is then not easy to utilize core to produce for some containers with thin neck, because core is not easy to take out after rotary press modelling.
Summary of the invention
It is an object of the invention to there are the problems referred to above for existing technology, the stretching device and manufacture method, this device and the manufacture method that propose a kind of thin neck container can utilize inside and outside adjustable roller spinning device can produce the thin neck shape container products of arbitrary shape easily and fast.
The purpose of the present invention can be realized by following technical proposal: the stretching device of a kind of thin neck container includes rotating main shaft, spinning roller wheel apparatus, tail top.Spinning roller wheel apparatus includes running roller, running roller support bar, running roller telescopic control device.Described running roller telescopic control device includes inner tube, outer tube, said inner tube is slidably overlapped within the outer tube, described running roller is arranged on running roller support bar end, inner pipe end and running roller support bar the other end chain connection, and outer tube end is connected by connecting rod link with running roller support bar.Inner tube, outer tube, running roller support bar and connecting rod are equivalent to constitute slide block four-bar mechanism, by controlling the relative slip of inner and outer pipes, can control being placed and taken out of running roller stretching in body radial direction, beneficially spinning roller wheel apparatus.Described tail top has the body of rod of elongated cylindrical, the inner tube of one spinning roller wheel apparatus is slidably enclosed within the body of rod on described tail top as internal rolling roller apparatus, for inner surface of container is carried out spinning, another spinning roller wheel apparatus and internal rolling roller apparatus be arranged in parallel as outside spinning roller apparatus, for container outer surface is carried out spinning.
In the stretching device of above-mentioned thin neck container, inner tube, outer tube are connected to control on piston and the cylinder body of the hydraulic cylinder of inner and outer tubes relative motion, and described hydraulic cylinder is controlled mobile by another linear drive apparatus.
In the stretching device of above-mentioned thin neck container, described running roller telescopic control device is symmetrically arranged with two groups of running rollers, running roller support bar and linkage.Stress balance when making spinning.
In the stretching device of above-mentioned thin neck container, the stretching device of this thin neck container has the rotation main shaft of two synchronous axial system being set up in parallel, tail top, internal rolling roller apparatus it is provided with, between outside spinning roller apparatus internal rolling roller apparatus on two tail tops on tail top.Realize the spinning to two blanks the most simultaneously, not only can improve efficiency, also can make outside spinning roller apparatus stress balance.
This stretching device makes the method for thin neck container and is such that adding man-hour, blank is accommodated between tail top and rotation main shaft, blank can be plate body or staving, then two rotation main shaft synchronous axial system are made, move axially while spinning running roller the contour shape according to product and control the inner and outer tubes relative motion of inside and outside spinning roller wheel apparatus, thus controlling running roller stretching in radial direction, in order to extrusion stretching goes out the profile of bending.
Compared with prior art, stretching device and the method for this thin neck container has the advantage that
The present invention passes through inside and outside spinning roller wheel apparatus cooperating, need not use core, can be spun to the thin neck shape container products of arbitrary shape, and two spinning parts can carry out spinning simultaneously, improves production efficiency.
