Enhanced Method and Equipment of Forging Bow-Shape Conjointed Rake

An enhanced method for forging a bow-shape conjointed rake with one-piece of steel, wherein the method includes the following steps:

• preparing a rectangular blank of steel of which the width is bigger than the width of the target bow-shape conjointed rake and the height is bigger than the longest rake tooth of the target bow-shape conjointed rake, and heating the rectangular blank to a target temperature;
• stamping the rectangular blank to mold a rake tooth with a rake handle blank reserved at both sides of the rake tooth slightly separated from the rake tooth, obtaining a rake main body with the rake tooth and the rake handle blank on one side and a rake back on the other side, and cutting off two corners of the rake back at a slant at the position of the rake handle blanks;
• bending the rake handle blanks away from the rake tooth, and horizontally forging and rotating the rake handle blanks to make them become column shape, respectively;
• heating the rake handle blank locally, stretching the rake handle blank to mold a rake handle, and bending the rake handle back to a direction reverse to the rake tooth;
• bending the rake handle inward and forging the two ends of the rake handle together;
• and
• bending all of the rake teeth of the bow-shape rake toward a same direction to become arc shape.
