Abstract
The contraction mouth frock of iron core case, relates to a kind of forming frock.Comprise bed die, bed die is provided with cannelure, iron core case opening upwards is placed in the cannelure of bed die, the upper port of iron core case protrudes upward the cannelure of bed die, the bed die of iron core case outer ring is fixed with the outer pressing mold of annular, the bed die of iron core case inner ring is fixed with interior press mold, be provided with outer ring necking forming film and inner ring in iron core case to dehisce shaping membrane, be provided with necking forming groove between the outer shroud week of outer ring necking forming film upper port and the outer pressing mold of annular, inner ring is dehisced to compress between the inner circumference of film upper port and interior press mold and is provided with flare formation groove; Outer ring reducing compresses film and inner ring dehisces to be equipped with ring compression mould between compression film.During use, under the utility model is placed in press, press down ring compression mould by press, make case unshakable in one's determination once-forming, labour intensity is low, and operating efficiency is high, and not modification after being shaped.
Description
Technical field
The utility model relates to a kind of forming frock, is specially a kind of contraction mouth frock of iron core case.
Background technology
In existing technology, case contraction mouth place unshakable in one's determination utilizes lathe to be processed at contraction mouth position, then welds with case unshakable in one's determination, grinding process after welding, and this method cost is high, and efficiency is low, and labour intensity is large, does not reach one-time formed effect.
Utility model content
It is high that the purpose of this utility model is to provide a kind of forming efficiency, and the contraction mouth frock of the rear indeformable iron core case that is shaped.
The technical scheme realizing above-mentioned purpose is: the contraction mouth frock of iron core case, it is characterized in that: comprise bed die, bed die is provided with the cannelure coordinated with iron core case, iron core case opening upwards is placed in the cannelure of bed die, the upper port of iron core case protrudes upward the cannelure of bed die, the bed die of iron core case outer ring is fixed with the outer pressing mold of annular, the bed die of iron core case inner ring is fixed with interior press mold, be provided with outer ring necking forming film and inner ring in iron core case to dehisce shaping membrane, necking forming groove is provided with between the outer shroud week of outer ring necking forming film upper port and the outer pressing mold of annular, inner ring is dehisced to compress between the inner circumference of film upper port and interior press mold and is provided with flare formation groove, outer ring reducing compresses film and inner ring dehisces to be equipped with ring compression mould between compression film.
Above-mentioned outer ring necking forming film and inner ring shaping membrane of dehiscing is all to be joined end to end the annular solid formed by polylith segmental arc.
During use, under the utility model is placed in press, press down ring compression mould by press, make case unshakable in one's determination once-forming, labour intensity is low, and operating efficiency is high, and not modification after being shaped.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure chart of outer ring necking forming film;
Fig. 3 is that inner ring is dehisced the structure chart of shaping membrane.
Detailed description of the invention
As Fig. 1, 2, shown in 3, the utility model comprises bed die 1, bed die 1 is provided with the cannelure 3 coordinated with iron core case 2, iron core case 2 opening upwards is placed in the cannelure 3 of bed die, the upper port of iron core case 2 protrudes upward the cannelure of bed die 1, the bed die 1 of iron core case 2 outer ring is fixed with the outer pressing mold 4 of annular, the bed die 1 of iron core case 2 inner ring is fixed with press mold 5 in coordinating with iron core case 1 center hole size, be provided with outer ring necking forming film 7 and inner ring in iron core case 1 to dehisce shaping membrane 6, outer ring necking forming film 7 and inner ring shaping membrane 6 of dehiscing is all to be joined end to end the annular solid formed by polylith segmental arc 8.
Be provided with necking forming groove 9 between the outer shroud week of outer ring necking forming film 7 upper port and the outer pressing mold 4 of annular, inner ring is dehisced to compress between the inner circumference of film 6 upper port and interior press mold 5 and is provided with flare formation groove 10; Outer ring reducing compresses film 7 and inner ring dehisces to be equipped with ring compression mould 11 between compression film 6.
During use, under the utility model is placed in press, press down ring compression mould 11 by press, realize under the pressure effect of the necking forming groove 9 of case 2 external port unshakable in one's determination between the outer pressing mold 4 of outer ring necking forming film 7 and annular necking forming, case unshakable in one's determination 2 inner port inner ring dehisce the flare formation groove 10 compressed between film 6 upper port and interior press mold 5 pressure effect under realize flare formation.
