Description
Technical field
The utility model is related to stamping equipment field, specifically a kind of cold heading die for manufacturing car spare tire fixing bolt
Has component.
Background technology
In recent years, as China's automobile manufacture industry rapidly develops, to the production technology and kind of all kinds of fastening parts of automobiles
It is required that higher and higher, such as certain car spare tire bolt product, feature is that length is long, need to fix the spare tyre of car, and to be prevented
Only car jolts and causes falling off for spare tyre in the process of running.Therefore, for the straightness of product and concentricity requirement
It is high；Generally for the machine-shaping on machining lathe of such product.But this processing technology is there is certain defect, by
The machine direction of metal inside can be destroyed after machining material removal in the metal material or even destroys metallic crystalline structure,
Mechanical properties and the plastically deformed performances such as intensity, rigidity to reduce metal product, so that the assembly after influencing whether
Performance, the defects of causing bolt not assemble normally.Therefore this kind of processing method, working efficiency is low, and waste of raw materials is serious, influences
Product quality.
Invention content
The purpose of the utility model is to overcome drawbacks described above, provide a kind of for manufacturing the cold of car spare tire fixing bolt
Upsetting die assembly.
In order to achieve the above object, the utility model is realized in this way：
It is a kind of for manufacturing the cold upsetting die of car component of car spare tire fixing bolt, including endoporus molding die combination and outer
Shape eurymeric die assembly；
The endoporus molding die combination includes material base head section necking die, necking down auxiliary section die and material base endpiece chamfering
Mold；Three molds are mutually inserted and form the combination of endoporus molding die, and material is disposed with respectively in three molds
Base head section necking down mold core, necking down supplemental core and material base endpiece chamfering mold core, the mold core is hard alloy material, and is worked as
After three molds are mutually inserted, the axial line of three mold cores is on the same line；Make material base by endoporus molding die combination
Head section, stage casing and endpiece shape reach moderate molding standard；
The shape eurymeric die assembly includes outside material base head section eurymeric mold, material base stage casing eurymeric mold and material base tail portion
Plum blossom molding die；Three molds are mutually inserted and form shape eurymeric die assembly, in three molds respectively successively
It is provided with material base head section eurymeric mold core, mold core described in plum blossom formation die core is hard outside material base stage casing eurymeric mold core and material base tail portion
Alloy material, and after three molds are mutually inserted, the axial line of three mold cores is on the same line；Pass through the positive pattern
Tool combination makes the head section of material base, stage casing formally be molded and the tail portion of material base is made to have outer plum blossom structure to make material base shape reach
Product design requirement.
This die assembly is used to above-mentioned design, and the material base Jing Guo pre- eurymeric is passed through to the cold-heading of two sets of different die assemblies
Afterwards, there is product design, in this way, avoiding in the machining operations such as traditional turning since External Shape complexity needs multistation to process
So as to cause axis disunity, material mechanical performance difference problem.
Description of the drawings
Fig. 1 is the structural schematic diagram that endoporus molding die combines in this die assembly.
Fig. 2 is the structural schematic diagram of shape eurymeric die assembly in this die assembly.
Specific implementation mode
The utility model is further illustrated below by way of specific embodiment.
It is a kind of for manufacturing the cold upsetting die of car component of car spare tire fixing bolt, including endoporus molding die combination and outer
Shape eurymeric die assembly；
As shown in Figure 1, the endoporus molding die combination includes material base head section necking die 1,2 and of necking down auxiliary section die
Material base endpiece chamfer mould 3；Three molds are mutually inserted and form the combination of endoporus molding die, in three molds respectively
It is disposed with material base head section necking down mold core 11, necking down supplemental core 21 and material base endpiece chamfering mold core 31, the mold core is hard
Matter alloy material, and after three molds are mutually inserted, the axial line of three mold cores is on the same line；Pass through the endoporus
Molding die combination makes head section, stage casing and the endpiece shape of material base reach moderate molding standard；
As shown in Fig. 2, the shape eurymeric die assembly includes material base head section eurymeric mold 4, material base stage casing eurymeric mold 5
With plum blossom molding die 6 outside material base tail portion；Three molds are mutually inserted and form shape eurymeric die assembly, in three moulds
Material base head section eurymeric mold core 41 is disposed in tool respectively, plum blossom shaping mould outside material base stage casing eurymeric mold core 51 and material base tail portion
Core 61, the mold core are hard alloy materials, and after three molds are mutually inserted, the axial line of three mold cores is same
On straight line；So that the head section of material base, stage casing is formally molded by the eurymeric die assembly and makes the tail portion of material base that there is outer plum blossom knot
Structure is to make material base shape reach product design requirement.
This die assembly is used to above-mentioned design, and the material base Jing Guo pre- eurymeric is passed through to the cold-heading of two sets of different die assemblies
Afterwards, there is product design, in this way, avoiding in the machining operations such as traditional turning since External Shape complexity needs multistation to process
So as to cause axis disunity, material mechanical performance difference problem.
