Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Embodiment one：
This preferred embodiment provides a kind of slip yoke preform manufacturing process, as shown in Figures 1 to 4, shown, including
Step A, pressure flow body is filled with the cavity of hollow tube 1 after hollow tube 1 is placed in mould, the part body of hollow tube 1 is having pressure
The lower outwards expansion of pressure effect of fluid forms the bulge 11 of tubulose, preform of the bulge 11 as the fork of slip yoke
Body, the bar portion 12 of at least part body in addition to bulge 11 of hollow tube 1 as slip yoke.Pressure flow body is preferably but not office
It is limited to water.The pressure of pressure flow body is not specifically limited, and can meet the pressure needed for shaping demand.
In the present embodiment, a bulge 11 can be used as (as referring to turn into) slip yoke fork or two
The preform of fork.The quantity of bulge 11 and position can be configured according to real needs, for example, can be located at hollow
The end of pipe 1 or inside (inside refers to the position of non-end).The quantity of fork corresponding to all bulges 11 on hollow tube 1
Preferably at least two, it once can shape the preform of multiple slip yokes.
The slip yoke preform manufacturing process that the present embodiment provides, by being filled with pressure flow body into hollow tube 1 come shape
Into bulge 11, and using the bulge 11 as the preform of slip yoke fork, rate of metal is high, production efficiency is high, nothing
Need to additionally heat, energy consumption it is low.
