Abstract
The present invention provides a manufacture method for an integral forming splined hub, which mainly solves the defects of time waste for the manufacture of a splined hub and high cost in the prior art. The method comprises that a straight pipe is positioned in a mould; liquid such as flexible rubber or oil or water, etc., is filled in the straight pipe; a filling device is then immediately extruded so as to seal openings at the front end and the back end of the mould; the operation of extrusion is then carried out; media penetrating the liquid such as flexible rubber or oil or water, etc., are extruded outwards, and the straight pipe can be extruded into a semifinished product easily; the semifinished product is then positioned into another extrusion mould, and a splined disk is extruded.
Description
The invention provides a kind of manufacture method of hub by integrally shaping.
The manufacture method of general flower hub in the prior art is to utilize roller to be rolled into semi-finished product one straight tube earlier substantially, utilizes an oil pressure pressurizing unit with its extrusion modling then.Though prior art energy hub by integrally shaping, but still have following defective, because prior art is to utilize roller to be rolled into semi-finished product, its moulding is progressively to finish, thereby process velocity is slow, because the time-consuming cost that causes improves; In addition, be rolled into semi-finished product by roller, be to roll out the required convex-concave surface shape of semi-finished product in theory, can be in fact be enough to remedy its hollow liner because filling is any in this straight tube in the roll extrusion process, therefore this straight tube surface pressurized produces distortion, and little when when distortion is big, make its surface inhomogeneous.
Purpose of the present invention is just in order to solve weak point of the prior art, and proposed a kind of manufacture method of hub by integrally shaping.This method is that filling as media, can be brought into play squeezing action from inside to outside with liquid such as soft rubber or oil, water in straight tube, can be easily with the straight tube one subsynchronous semi-finished product that are squeezed into.
The object of the present invention is achieved like this: the manufacture method of hub by integrally shaping, be that straight tube is placed a mould, then in this straight tube filling with liquid such as soft rubber or oil, water, at first seal the front and back ends opening of this mould after the pressurizing unit starting, the work of pushing again thereafter, extruding force is that media becomes semi-finished product with the straight tube bulging with this soft rubber or oil, water, semi-finished product is placed another extrusion die to extrude floral disc again.
The present invention compared with prior art has following advantage: at first, utilize technology of the present invention not only can shorten man-hour, and can reduce cost easily with the straight tube one subsynchronous semi-finished product that are squeezed into; Secondly, finish indirectly through this soft rubber or liquid such as oil, water owing to make semi-finished product, so its smooth surface, even.
The present invention has 10 width of cloth accompanying drawings, and wherein Fig. 1 can make the accompanying drawing of specification digest.

Below in conjunction with accompanying drawing most preferred embodiment of the present invention is further described.
Technological process of the present invention as shown in Figure 1, when making colored hub of the present invention, successively as follows:
A, get a straight tube 1: the hollow tube 1 of at first taking a metal is as material;
B, media extruding program: this straight tube 1 is inserted in the extrusion die 2, then with filling soft rubber 3 or oil in this straight tube 1, liquid such as water, and then start oil pressure pressurizing unit 4 immediately, utilize two oil hydraulic cylinders 41 seal in advance this mould 2 before, open rearward end 21 (as shown in Figure 5), the work of pushing again thereafter (as shown in Figure 6), extruding from inside to outside, promptly the inside by this straight tube 1 expands outwardly, act on and see through this soft rubber 3 or oil therebetween, liquid medias such as water, can be easily make it rely on mould 2 the tube wall crimp of this straight tube 1, form the semi-finished product 5 (as shown in Figure 3) identical with these mould 2 appearance, this moment, oil gear 4 was return original position, and open mould 2 (as shown in Figure 7), then again this soft rubber 3 is extracted out from these semi-finished product 5 (as using oil, liquid such as water are media (as Fig. 8), then with the oil of media, liquid such as water are discharged and are got final product), so far the well-balanced semi-finished product of a smooth surface are made;
C, oil pressure extrusion modling program: the semi-finished product 5 of institute's moulding are inserted in another extrusion die 7 push, but extrusion molding has the colored hub finished product (as shown in Figure 4) of floral disc 61 after the afterburning effect.
It should be noted that, because in this media extruding program, its extrusion modling is to be media by a soft rubber 3 or liquid such as oil, water, in other words, utilize this soft rubber 3 or liquid such as oil, water liner for media, be to see through this media liner with active force to reach the tube wall that this fills out pipe 1 again, so under squeezing action, remove to oppress hard material with flexible material, from guaranteeing the unlikely tube wall that is corrupted to this straight tube 1, semi-finished product 5 surfaces of natural institute moulding are comparatively smooth all to be claimed, and more indefectible, and quality is higher.
Claims (1)
1. the manufacture method of a hub by integrally shaping, the steps include: straight tube is placed a mould, then in this straight tube filling with soft rubber or oil, water liquid, at first seal the front and back ends opening of this mould after the pressurizing unit starting, the work of pushing again thereafter, extruding force is that media becomes semi-finished product with the straight tube bulging with this soft rubber or oil, water, semi-finished product is placed another extrusion die to extrude floral disc again.
