Abstract
The utility model relates to a 330ml steel draw punch of a 202 necked-in can type for a two-piece can. The draw punch is provided with an inner chamber body, a step is formed in the middle of an outer wall, and the outer wall at the tail end of the punch forms a bevel angle. The length of the outer wall of the punch from the step to the front end is 3.7915 inches, the length of the step area is 0.4331 inch, and the height of the step is 0.0220 inch. The bevel angel at the tail end of the punch is 6 DEG. The height of the middle section of the inner chamber of the punch is 2.0 inches, the step is formed at the junction of the middle section of the inner chamber and the front section of the inner chamber, and the height of the front section of the inner chamber is 1.6 inches. According to the utility model, the lengths of the thin wall area and the step area are reduced so as to increase the length of the thick wall area, and therefore, the necked-in folds caused by insufficient length are avoided. In addition, the height of the step is decreased, so that metal flow drop and deformation in the thin wall area and the thick wall area are lowered, the metal increment in the thick wall area of 202 can type growth is satisfied, and waste products caused by uneven wall thickness are reduced. In addition, the height of the inner chamber is reduced, so that the weight of the punch is reduced, and drawing precision is improved.
Description
Technical field
The utility model belongs to the mental package apparatus field, relates to a kind of 330ml pop can steel two piece can with 202 necked-in can type stretching drifts.
Background technology
206 jars of type punch structures of original pop can are as shown in Figure 1.
Drift matches with stretching annular mould, forms the gap that the respective regions height does not wait along the appearance profile of drift.In actual production process, metal flows along the gap and cools off, and finally forms the blank jar.
In use there is following problem in original plug:
(1) present main flow jar type in the world is 202 jars of types, and the conversion of 206 jars of types to 202 jars of types also will be carried out in the domestic market.But original drift is 206 jars of type special punch, and its produced blank jar can't be used to produce 202 jars of types, and drift is expensive simultaneously, scraps and purchases separately with cost greatly.
(2) face that the installs and fixes height at accent tail two ends consistent (1.8281 inches) in the former drift causes when the installation and removal drift, extremely requiring great effort, and has also increased the wearing and tearing of inner chamber and jumper bar.
Summary of the invention
The purpose of the utility model is to design a kind of 330ml steel two piece can with 202 necked-in can type stretching drifts; Through profile transformation to original 206 drifts; Make the blank jar of its production can satisfy the production demand of 202 jars of types, also can be used for the manufacturing of new 202 jars of type drifts simultaneously.
For achieving the above object, the technical scheme of the utility model is:
330ml steel two piece can has an inner chamber body with 202 necked-in can type stretching drifts, and a step is established at its outer wall middle part, and drift tail end outer wall is the oblique angle; It is characterized in that the drift outer wall is 3.7915 inches from the length L 1 of step to front end, stepped region length L 2 is 0.4331 inch, and drift shoulder height H1 is 0.0220 inch.
Further, the tail end oblique angle of drift is 6 degree.
Again, the inner chamber miding level height H2 of drift is 2.0 inches, and a step is established in inner chamber stage casing and inner chamber leading portion junction, and this step is the chamfering of 60 degree, and inner chamber leading portion height H 3 is 1.6 inches.
The utility model shortens to 3.7915 inch from the length of step to front end (drift tenuity) by original 3.9020 inches with the drift outer wall; Simultaneously stepped region length shortens to 0.4331 inch by original 0.4724 inch, and the drift shoulder height is reduced to 0.0220 inch by original 0.0232 inch; The tail end oblique angle of drift changes 6 degree into by 3 degree; The inner chamber middle-end height of drift increases to 2.0 inches by original 1.9 inches, and the B place becomes the chamfering of 60 degree by original R0.03 inch fillet, and the inner chamber open height changes 1.6 inches into by original 1.8281 inches.
The beneficial effect of the utility model:
1) the utility model is through reducing the length of tenuity and stepped region, thereby increased the length in heavy wall district, guaranteed the high requirement of 202 jars of types to the heavy wall section length, avoids the necking down gauffer that occurs inadequately because of length.Simultaneously through reducing shoulder height; Mobile drop of thick and thin wall regional metal and deflection have been reduced; Total metal material amount of guaranteeing 206 jars of types is when reaching production internal control quality level; Can satisfy the heavy wall district metal recruitment that 202 jars of types increase, reduce because of the even waste product that produces of wall unevenness.
2) because the thick wall area of 202 jars of types is longer, have big resistance when behind drawing and forming, taking off jar, so the utility model increases drift tail end angle, improve and take off a jar efficient.
3) the utility model through reducing the inner chamber height, reduces the weight of drift under the prerequisite that satisfies the drift requirement of strength, improves the stretching precision; The reduction of inner chamber leading portion height makes the stationary plane of inner chamber leading portion (interior accent) and afterbody form drop, is convenient to the installation and removal drift; The step of inner chamber stage casing and inner chamber leading portion junction becomes chamfering by fillet, is convenient to processing and assembling.
Description of drawings
Fig. 1 is the structural representation of the utility model drift.
Fig. 2 is the A portion enlarged diagram of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, the 330ml steel two piece can of the utility model has an inner chamber body 100 with 202 necked-in can type stretching drifts 1, and a step 11 is established at its outer wall middle part, and drift tail end outer wall is oblique angle C; The drift outer wall is 3.7915 inches from the length L 1 of step 11 to front end, and stepped region length L 2 is 0.4331 inch, and drift step 11 height H are 0.0220 inch.
The tail end oblique angle of drift is 6 degree.Inner chamber stage casing 102 height H 2 of drift are 2.0 inches, and a step is established with inner chamber leading portion 101 junctions in inner chamber stage casing 102, and this step is the chamfering B of 60 degree, and inner chamber leading portion 101 height H 1 are 1.6 inches.
The utility model is through reducing the length of tenuity and stepped region, thereby increased the length in heavy wall district, guaranteed the high requirement of 202 jars of types to the heavy wall section length, avoids the necking down gauffer that occurs inadequately because of length.Simultaneously through reducing shoulder height; Mobile drop of thick and thin wall regional metal and deflection have been reduced; Total metal material amount of guaranteeing 206 jars of types is when reaching production internal control quality level; Can satisfy the heavy wall district metal recruitment that 202 jars of types increase, reduce because of the even waste product that produces of wall unevenness.Simultaneously, the utility model increases drift tail end angle, improves and takes off a jar efficient.In addition, the utility model reduces the weight of drift through reducing the inner chamber height, improves the stretching precision; The step of inner chamber stage casing and inner chamber leading portion junction becomes chamfering by fillet, is convenient to processing and assembling.
