Abstract

The invention discloses metal cylinder flanging equipment, comprising a working platform; the working platform is provided with a cylinder locating component, an arc flanging component and a driver; the cylinder locating component comprises a rotating shaft, a cylinder circle-expanding mold, a swaging tray and a locking device; the rotating shaft is connected with the driver in a transmission way and fixed with the cylinder circle-expanding mold; the swaging tray is arranged above the cylinder circle-expanding mold and provided with the locking device; the arc flanging component comprises a rotating flanging mold which is vertically fixed on the working platform and the section of the flanging mold is round and the two longitudinal sidelines of the mold are hyperbola. In the proposal, the location of a cylinder fixes a metal cylinder and drives the metal cylinder to rotate at the same time; when the metal cylinder rotates, the inside toward the end opening is in contact with the flanging mold and the arc extension of the metal cylinder edge is realized. Therefore, the labor intensity of workers is reduced, and the productivity, the product precision and the yield are promoted.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a metal cylinder flanging device. Background technique [0002] Flanging the sides of some metal cylinders can improve the strength of the cylinder and achieve the purpose of saving materials. In addition, the arc flanging structure treatment on the sides of the metal cylinder of the axial flow fan can make it have a streamlined shape. Shape, reduce the resistance of the fluid when the fan is running, and save energy. [0003] The fan manufacturing industry often processes the two ends of the metal cylinder of the axial flow fan. Generally, one end is an arc-shaped structure, similar to the shape of a bell mouth, and the other end is an "L"-shaped flange. Currently, it is processed in the fan manufacturing industry. The equipment used in the above structure includes a fixture and a joystick. The fixture can clamp the metal cylinder to rotate, and one end of the joystick is fixed...
