Metal blade forming machine

Abstract

The invention relates to a metal blade forming equipment used for processing heating and ventilating equipment. A metal blade forming machine comprises a frame (1), a motor (6) and a rolling forming mechanism (3), a material cutting mechanism (4) and a material throwing mechanism (5) which are arranged on the frame. The blade forming machine adopts fully-automatic operation and has high processing efficiency; the rolling forming mechanism ensures that the radians of a profiled blade are consistent, and the whole blade does not flex easily; the material cutting mechanism ensures the standard of the cut blade length and size; and the material throwing mechanism ensures the consistency and the high speed for outputting the formed blade.

Description

technical field

[0001] The invention relates to a forming device for processing metal blades used in heating and ventilation equipment. Background technique

[0002] Metal blades have an arc-shaped cross-section and are commonly used components in HVAC equipment. For example, a cross-flow fan is composed of multiple metal blades arranged along the grooves on the circumference of the flange. The existing metal blade molding is divided into two steps: forming and cutting. First, the metal blade is pressed with a pressure wheel device to press out the required radian, and then the pressed blade is taken out and placed on a punching machine to cut off. The cut length is manually controlled. . The defects of the existing equipment are: the semi-automatic operation is adopted, the processing efficiency is low, the radian of the blade after profiling is easily deformed, and the truncated length cannot be uniform in size.
