Abstract

The punching device has punch head with proper outer shape and thus punches the punched material into square cone part with minimized tension difference and no crack in the punched material while the punch head deepens to form. The fixtureand the punch mold are provided with stepped part, so that after the machined material is fixed with the fixture and the punch mold, it may be formed in stepped shape. Force is applied to the machined material drawn to between the punch head and the punch mold to overcome the resistance for pass through the step, and this can control properly the amount of the machined the drawn to between the punch head and the punch mold, so as to suppress exceed entrance, equalize the tension in different parts of the machined material, reduce the deformation in various corner parts and inhibit crack likely produced in different corner parts.

Description

technical field [0001] The present invention relates to a press device for drawing and forming a conical member of an air-conditioning exhaust port device, and particularly relates to a press device capable of drawing and forming a material to be processed properly without cracking. Background technique [0002] In the exhaust port device for air conditioners, the multi-layer conical exhaust port device has an outer cone and a middle cone. Considering its strength and cost, such conical parts are generally formed by metal plates. In the multi-layer conical exhaust port device, when the bottom shape is a square or rectangular square cone, the existing manufacturing method of the conical part is to mold each of the four members of each inclined surface part, It is manufactured integrally by welding the end portions corresponding to the corner portions to each other. [0003] The manufacturing of the conventional square cone-shaped parts is carried out as described above, and ...
