Description
Technical field
The present invention relates to the punch process field of automotive engine component, be specially the cut-out mould of air outlet taper pipe shell of automobile engine exhaust system.
Background technology
A kind of air outlet taper pipe shell of automobile engine exhaust system, its structure is shown in Fig. 1, it is applied to automobile engine exhaust system hot junction, during installation one end be connected with purifier carrier, the Flange joint of the other end and engine side, its parts precision requires high, these parts mostly were stainless steel precision castings in the past, and therefore its processing cost is high and working (machining) efficiency is low.In order to reduce the processing cost of these parts and improve working (machining) efficiency, now progressively adopt the method for punch process to produce this parts, according to the design feature of these parts, these parts are divided into upper half shell 22 and lower half shell 23 in punch process, see Fig. 2 and Fig. 3, the process route of its punch process is first distinguish punch forming upper half shell and lower half shell, again upper half shell and lower half shell split are welded into entirety, in figs. 2 and 3, 24 is the big opening end of upper half shell, 25 is the osculum end of upper half shell, 26 is the big opening end of lower half shell, 27 is the osculum end of lower half shell, when upper half shell 22 and lower half shell 23 split, the big opening end 24 of upper half shell and big opening end 26 split of lower half shell, the osculum end 25 of upper half shell and osculum end 27 split of lower half shell.In order to reduce manufacturing procedure, improve working (machining) efficiency, the drawing and forming of upper half shell and lower half shell adopts the method connecting and expect integrated punching drawing and forming, need cutting workpiece to be formed independently upper half shell and lower half shell after connecting material integrated punching drawing and forming, see Fig. 4, because the workpiece with form surface connected after material integrated punching drawing and forming is complicated, and be thin-wall case workpiece, upper half shell is caused because Workpiece fixing compresses difficulty when its punching press is cut off, the cut-out limit place of lower half shell easily occurs wrinkling, the defects such as depression, after cutting off processing, upper half shell and lower half shell need to carry out shaping processing more respectively, the working (machining) efficiency of whole workpiece is reduced.In Fig. 1,28 is upper half shell 22 and the welded seam of lower half shell 24, and in Fig. 4,29 illustrate for cutting line.
Summary of the invention
For the problems referred to above, the invention provides the cut-out mould of air outlet taper pipe shell of automobile engine exhaust system, it can ensure to cut off the complete of rear upper half shell and lower half shell housing profile.
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cope match-plate pattern and fixed head, under described fixed head is installed on described cope match-plate pattern, described lower die structure comprises lower bolster, installing plate, described lower bolster is installed on described installing plate by mould pin, described upper die structure and lower die structure to be led matched moulds by slip independent pilot part, it is characterized in that: described upper die structure also comprises cut-out punch structure, described lower die structure also comprises Workpiece fixing cavity die structure.
It is further characterized in that:
Described cut-out punch structure comprises holding pad, cuts off punch, described holding pad to be installed on below described fixed head and to be connected with described fixed head with unloading bolt by spring, and described cut-out punch to be installed in described fixed head and to be passed down through described holding pad;
Also be provided with discharging guide pillar in described fixed head, have pilot hole in corresponding described discharging guide pillar position, described holding pad, be provided with discharging guide pin bushing in described pilot hole, described discharging guide column sleeve is loaded in described discharging guide pin bushing;
Described Workpiece fixing cavity die structure comprises locating piece, upper half shell cuts off re-entrant mold mold insert, lower half shell cuts off re-entrant mold mold insert, described locating piece is installed on described lower bolster, described upper half shell cuts off re-entrant mold mold insert, lower half shell cuts off re-entrant mold mold insert and cuts off limit insert in described locating piece along correspondence respectively, workpiece upper half shell stub end limited block is installed in the laterally left side of described locating piece, described workpiece upper half shell stub end limited block in described cope match-plate pattern, described locating piece is also provided with workpiece lower half shell stub end limited block by end locating piece limit mounting.
When shell workpiece after adopting mould of the present invention to expect one-body molded processing to company carries out punching press cut-out, workpiece is tightly pressed in locating piece by its holding pad, upper half shell cuts off re-entrant mold mold insert, lower half shell cuts off on re-entrant mold mold insert, and workpiece upper half shell stub end limited block, workpiece lower half shell stub end limited block plays good position-limiting action to workpiece, therefore it effectively to avoid because Workpiece fixing compresses difficulty upper half shell after the cut-out that causes, it is wrinkling that lower half shell cuts off limit, the defects such as depression, guarantee accurate processing, thus effectively reduce follow-up shaping manufacturing procedure, enhance productivity, and between fixed head and holding pad, be also connected with discharging guide pillar, the reliable compression of holding pad to workpiece can be ensured further, thus guarantee to cut off the accurate of punch cutting position, prevent from cutting partially.
