Abstract
The utility model discloses a flaring die and particularly discloses a wheel rim middle-section flaring die. The wheel rim middle-section flaring die provided includes a lower die having an inner conical surface and an upper outer die having an outer conical surface, the center of the upper outer die is provided with an inner cavity divided into three sections in the circumferential direction, the upper-section cavity and the lower-section cavity are in a cylindrical structure, the middle-section cavity is provided with an inner conical structure, a position-specified surface is formed between the top of the inner conical surface of the middle-section cavity and the bottom of the upper-section cavity, an upper inner die matched with the inner cavity of the upper outer die in outline is arranged in the inner cavity of the upper outer die, the upper section and the middle section of the upper inner die are longer than the upper-section cavity and the middle-section cavity of the upper outer die, and the upper outer die and the upper inner die are mutually staggered. By adopting such a structure, the materials for manufacturing the upper die can be reduced, and the manufacturing cost is saved; meanwhile, because the upper outer die and the upper inner die are mutually staggered, the upper inner die can be easily pulled out when the flaring is completed, thereby improving the flaring efficiency.
Description
Technical field
The utility model relates to a kind of flaring die, specifically a kind of wheel rim stage casing flaring die.
Background technology
Wheel rim is parts important in automobile industry, in the process of making wheel rim, often need the pipe in stage casing to carry out enlarging processing, existing flaring die comprises patrix and a counterdie of a solid construction, the outer surface of patrix and the inner surface of counterdie are provided with inner conical surface and the male cone (strobilus masculinus) cooperatively interacting, the defect that adopts existing this mould is because the diameter of wheel rim is larger, after enlarging, in the process of extracting patrix out, wheel rim can rebound, patrix is held tightly, and patrix is solid structure, thus on the one hand, the material usage of existing mold is many, manufacturing cost is high, make on the other hand patrix be difficult to extract out, time-consuming, reduced the efficiency of enlarging.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly not only can reduces mold materials consumption, reduces die manufacturing cost and improves the wheel rim stage casing flaring die of enlarging efficiency.
In order to solve the problems of the technologies described above, wheel rim of the present utility model stage casing flaring die, comprise the counterdie with inner conical surface and the upper external mold with male cone (strobilus masculinus), the center of upper external mold is provided with an inner chamber that is divided in a circumferential direction three sections, epimere cavity and hypomere cavity are set to tubular structure simultaneously, stage casing cavity is set to an inner conical surface structure, between the top of stage casing cavity inner conical surface and the bottom of epimere cavity, form a confined planes, in the inner chamber of upper external mold, be provided with the upper internal mold that the inner chamber of an exterior contour and upper external mold cooperatively interacts, the upper segment length of upper internal mold and middle segment length are longer than the length of epimere cavity and the length of stage casing cavity of external mold and by the cone structure cooperatively interacting, upper external mold and upper internal mold are staggered mutually.
The below of described counterdie is provided with fixedly cushion block.
On the step surface of described upper external mold, be provided with a shoulder hole, on the step surface of upper interior die tip, be provided with screwed hole, trip bolt can be through in shoulder hole precession screwed hole.
Adopt after above-mentioned structure, because the center of upper external mold is provided with an inner chamber that is divided in a circumferential direction three sections, in the inner chamber of upper external mold, be provided with the upper internal mold that the inner chamber of an exterior contour and upper external mold cooperatively interacts, not only can reduce thus and manufacture patrix material used, save manufacturing cost, simultaneously, because upper external mold and upper internal mold stagger mutually, after enlarging completes, can exit easily upper internal mold, improve the efficiency of enlarging.
Accompanying drawing explanation
Fig. 1 is partial cross section's structural representation of the utility model wheel rim stage casing flaring die.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, wheel rim of the present utility model stage casing flaring die is described in further detail.
As shown in the figure, wheel rim of the present utility model stage casing flaring die, comprises the counterdie 1 with inner conical surface and the upper external mold 2 with male cone (strobilus masculinus), and the male cone (strobilus masculinus) of the inner conical surface of counterdie 1 and upper external mold 2 cooperatively interacts, and the below of counterdie 1 is provided with adjustable for height fixedly cushion block 4, the center of upper external mold 2 is provided with an inner chamber that is divided in a circumferential direction three sections, epimere cavity and hypomere cavity are set to tubular structure simultaneously, stage casing cavity is set to an inner conical surface structure, between the top of stage casing cavity inner conical surface and the bottom of epimere cavity, form a confined planes, in the inner chamber of upper external mold 2, be provided with the upper internal mold 3 that the inner chamber of an exterior contour and upper external mold 2 cooperatively interacts, the step surface 6 forming on upper internal mold can be mutually spacing with the step surface of upper external mold 2, the upper segment length of upper internal mold 3 and middle segment length are longer than respectively the length of epimere cavity and the length of stage casing cavity of external mold 2 and by the cone structure cooperatively interacting, upper external mold 2 and upper internal mold 3 are staggered mutually, now go up the inner conical surface of external mold 2 and the male cone (strobilus masculinus) of upper internal mold 3 leads mutually, can between the step surface of upper external mold 2 and the step surface on upper internal mold 3 tops, form an adjusting play thus, the hypomere of upper internal mold 3 is shorter in length than the length of external mold 2, it should be noted that, the entire length of upper external mold is identical with the entire length of upper internal mold, on the step surface 6 of upper external mold, be provided with a shoulder hole, on the step surface on upper internal mold 3 tops, be provided with screwed hole, trip bolt can be through in shoulder hole precession screwed hole.
Its operation principle is as follows:
When needs carry out enlarging to wheel rim, first wheel rim 5 is heated to suitable temperature, then wheel rim 5 is placed on counterdie 1 and adjusts to the height that horn mouth requires between external mold 2 and by the fixedly cushion block 4 of counterdie below, depress again internal mold and upper adventitia, when the bottom surface of upper internal mold and upper adventitia is equal, mention internal mold, complete pressing process.
