Abstract
Motor transmission gear is passed through many hands or places and is expanded base assembling die, including gear base die and gear base cushion, gear base die division has a hole of having a perfect understanding along the axis, and gear base cushion is placed in the gear base die downtheholely, gear base cushion includes gear base cushion cover and gear base cushion core, and gear base cushion ways is outside gear base cushion core. Gear base die includes gear base die plate insert and gear base die case, gear base die ways outside gear base die plate insert, the hole is seted up along gear base die plate insert axis. The utility model provides a motor transmission gear is passed through many hands or places and is expanded base assembling die adopts the modularized design theory, with easy wearing part and the phase separation of difficult wearing and tearing portion in gear base die and the gear base cushion, after easy wearing part takes place to damage, directly to its replace can, and other parts can also continue the use to prolong the mould utility life -span relatively, reduced the cost of manufacture of mould.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of automobile gearbox gear rolling base assembling die.
Background technology
As shown in Figure 1, it all adopts H13 material to make primarily of wheel blank die and wheel blank die cushion block composition to existing automobile gearbox gear rolling blanking mold.Wherein wheel blank die and wheel blank die cushion block coordinate, and the step 21 on wheel blank die cushion block top is for the seam position of shaping finished product.Wheel blank die endoporus is used for the cylindrical position of molded blank.The shortcoming of this mould is: in forging molding process, and step 21 position is stressed maximum, is secondly die inwall.After stepped portions abrasion deformation, whole die cushion block will be changed; After the distortion of die inner wall abrasion, whole die will be changed, thus it is low to result in die life, and die cost is high, waste resource.
Utility model content
For above-mentioned defect, the utility model aims to provide a kind of knockdown automobile gearbox gear rolling blanking mold.
The technical scheme of this automobile gearbox gear rolling base assembling die is achieved in that
Described automobile gearbox gear rolling base assembling die, comprise wheel blank die and wheel blank cushion block, wheel blank die has inner through hole along axis, wheel blank cushion block is placed in wheel blank die endoporus, described wheel blank cushion block comprises wheel blank cushion block cover and wheel blank cushion block core, and wheel blank cushion block cover is placed on outside wheel blank cushion block core.
Further, described wheel blank die comprises wheel blank die plate insert and wheel blank die case, and wheel blank die case is placed on outside wheel blank die plate insert, and described endoporus is offered along wheel blank die plate insert axis.
Concrete, described wheel blank cushion block core is provided with the round table-like step raised up.
In addition; described wheel blank die also mates wheel blank die pad; described wheel blank cushion block also mates wheel blank cushion block pad; wheel blank die pad is installed under wheel blank die plate insert and wheel blank die case; its center has the circular hole holding wheel blank cushion block pad; wheel blank cushion block pad is installed under wheel blank cushion block cover and wheel blank cushion block core, and is fastened by bolts.
Automobile gearbox gear rolling base assembling die provided by the utility model, adopt modular design concept, part easy to wear in wheel blank die and wheel blank cushion block and not easily wear are separated, after part easy to wear is damaged, directly it is replaced, and other parts can also continue to use, thus relatively extend the mold use life-span, reduce the cost of manufacture of mould.

In figure: 1. wheel blank die plate insert, 2. wheel blank die case, 3. wheel blank die pad, 4. wheel blank cushion block cover, 5. wheel blank cushion block core, 6. bolt, 7. wheel blank cushion block pad, 11. endoporus, 21. steps.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Automobile gearbox gear rolling base assembling die described in the utility model, as shown in Figure 2, comprise wheel blank die and wheel blank cushion block, wheel blank die has inner through hole 11 along axis, wheel blank cushion block is placed in wheel blank die endoporus 11, wheel blank cushion block is divided into part easy to wear and not easily wearing part by us, and described wheel blank cushion block comprises wheel blank cushion block cover 4 and wheel blank cushion block core 5, and wheel blank cushion block cover 4 is placed on outside wheel blank cushion block core 5.Concrete, described wheel blank cushion block core 5 is provided with the round table-like step 21 raised up, and this step 21 is position easy to wear.After abrasion deformation appears in this place, only need change wheel blank cushion block core 5, other parts do not need to replace, and can continue to use.
In like manner, wheel blank die is divided into part easy to wear and not easily wearing part by us, described wheel blank die comprises wheel blank die plate insert 1 and wheel blank die case 2, wheel blank die case 2 is placed on outside wheel blank die plate insert 1, described endoporus 11 is offered along wheel blank die plate insert 1 axis, and this endoporus 11 hole wall is position easy to wear.After abrasion deformation appears in this place, only need change wheel blank die plate insert 1, other parts do not need to replace, and can continue to use.
In addition; for the consideration of saving Mold Making cost; described wheel blank die also mates wheel blank die pad 3; described wheel blank cushion block also mates wheel blank cushion block pad 7; wheel blank die pad 3 is installed under wheel blank die plate insert 1 and wheel blank die case 2; its center has the circular hole holding wheel blank cushion block pad 7, and wheel blank cushion block pad 7 is installed under wheel blank cushion block cover 4 and wheel blank cushion block core 5, and fastening by bolt 6.
Described wheel blank die case 2, wheel blank die pad 3, wheel blank cushion block pad 7 are made by 42CrMo and replace H13.Wheel blank die plate insert 1 still adopts H13 material, and wheel blank cushion block core 5 adopts 3Cr3Mo3VNb material.Statistical Comparison is known, and the orthodox car gearbox gear rolling blanking mold life-span, service life brought up to 20000 by this automobile gearbox gear rolling base assembling die at 4000-5000 part.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
