Cast into the process of design shape, is to utilize external force, metal stock is produced by instrument or mould by high temperature and high pressure
Plastic deformation, so as to obtain a kind of processing method with definite shape, size and inherent quality blank, part, the mistake of forging
Journey can make the higher material of density, and product can be allowed to have more the tired characteristic of anti-metal.
The content of the invention
The utility model purpose is to provide a kind of shaped device for changeable bicycle handlebar stem, the outer shaping of the forging mold
Punching is connected with outer form die plate by way of pin is contacted with pin-and-hole by coincideing, and assembles simple and convenient and is easy to tear open
Unload.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of shaping for changeable bicycle handlebar stem
Device, the forging mold includes left mould benevolence, right mould benevolence, outer shaping punching, outer form die plate, plug and interior shaping red seat, institute
State the relative surface of left mould Renhe right mould benevolence and have left-handed form groove, right shape groove, so as to be formed between the right mould benevolence of left mould Renhe
One die cavity；
The lower surface of interior shaping red seat is fixed in the plug upper end, and the plug lower end is drift end, and the plug is embedding
In the central through hole for entering outer shaping punching, the side surface positioned at the outer shaping punching is provided with least two semicircle groove, this at least two
Semicircle groove is located at central through hole both sides respectively；
The outer form die plate center is provided with an installation through-hole, along outer form die plate in-plane and logical positioned at installing
Hole both sides are had in pin-and-hole, the installation through-hole of the outer embedded outer form die plate of shaping punching, and latch insertion is outer to be molded
It coincide in the pin-and-hole of die plate and with the semicircle groove of outer shaping punching and contacts.
Further improved scheme is as follows in above-mentioned technical proposal：
1. in such scheme, the side surface positioned at the outer shaping punching is provided with 4 semicircle grooves, wherein 2 are located at center
Through hole side, another 2 are located at central through hole opposite side.
2. in such scheme, the end face at the drift end of the plug is taper surface.
Because above-mentioned technical proposal is used, the utility model has following advantages and effect compared with prior art：
The utility model is used for the shaped device of changeable bicycle handlebar stem, and it is along outer form die plate in-plane and positioned at peace
Dress through hole both sides are had in pin-and-hole, the installation through-hole of the outer embedded outer form die plate of shaping punching, and latch insertion is outer
It coincide in the pin-and-hole of form die plate and with the semicircle groove of outer shaping punching and contacts, outer shaping punching and the connection of outer form die plate
Mode so that assembling is simple and convenient and is readily disassembled；Secondly, the end face at the drift end of plug is taper surface, the design of taper surface,
So that reaching the effect of preferable punching press in a short time.
