The composite die of composite die 3 and automobile drive axle housing lid edge-cutting and hole-punching is molded by automobile drive axle housing lid
Workpiece after 4 processing is sent to automobile drive axle housing lid boss plane leveling mold 5 and is processed, and steps are as follows：
The Drive axle housing lid boss plane leveling mold 5 of the present invention is mounted on single-point open type steam-operating 100T by the first step
On forcing press.
Second step, by workpiece（Axle housing lid 515）It is placed on upper surface and the excellent power glue of lower retainer 516 of leveling lower die 511
Upper surface, and the round hole in 515 boss plane of axle housing lid is made to be sleeved on the outer edge of positioning pin 59.
Third walks, and starts forcing press and carries out punch process to axle housing lid 515, workbench is with leveling upper mold 57 on lathe
It is moved downward with the excellent power glue of upper binder 56, flattens upper mold 57 first and contacted with positioning pin 59 and continue to move downward, positioning pin 59
With compression spring 510 because the thrust upward that compression generates moves downward, then flattens upper mold 57 and the excellent power glue 56 of upper binder is same
Step contacts with axle housing lid 515 and continues to move downward, and until lathe runs to bottom dead centre, makes axle housing lid 515 in leveling
The leveling of part plan is completed in the cavity formed between mould 57, leveling lower die 511 and positioning pin 59.
4th step, forcing press upper table face, leveling upper mold 57 and the excellent 56 upward return of power glue of upper binder, compression spring 510 are released
Release compressive deformation pressure by positioning pin 59 upwards jack up, with hand by the axle housing lid 515 flatten from flatten lower die 511 it is upper
It is taken out on surface and the upper surface of the excellent power glue of lower retainer 516 and overall processing can be completed.
The present invention realizes the molding of automobile drive axle housing lid, and punching, trimming and boss plane flatten the one of process
Body, is molded the molding concave die of composite die and the compound convex-concave mode structure that punch-pin and forming convax mould collectively form of typewriting can make
Blank is completed at the same time molding and typewriting two procedures in a working cycles, can promote productive temp, increase production capacity, reduces life
Produce cost, it is ensured that blank forming process and discharging process are stablized, and can guarantee that the face shaping of workpiece is regular and strength character is steady
It is fixed；
The compound convex-concave mode structure that piercing punch, trim die, punching concave die and trimming punch collectively form can make base
Material is completed at the same time punching and trimming two procedures in a working cycles, can promote productive temp, increase production capacity, reduces production
Cost；
The material-supporting device of boss plane leveling mold can be such that blank reforming process stablizes, it is ensured that axle housing lid and its boss are flat
The face shaping in face is regular and strength character is stablized, and can improving production efficiency.
