Problems solved by technology
[0002] With conventional forming methods, it is usually impossible to complete the fixed angle iron with angle reinforcement at one time
Therefore, the corner reinforcing part may not be formed smoothly, or the corner reinforcing part may be damaged, resulting in insufficient strength of the fixed angle iron.
[0003] At this time, it must be completed with more engineering times, but the processing cost is wasted; or it is produced by casting or die-casting, and the time and cost of mold and machine are more
[0004] Therefore, the forming method of the known fixed angle iron and the fixed angle iron have disadvantages that still need to be improved

A fastening angle bar molding method includes: providing a molding material piece having a through hole; providing a first mold having a protruding portion; providing a second mold having a dented portion which matches the protruding portion of the first mold to form a compressing space; placing the molding material piece between the first mold and the second mold, allowing the first mold and the second mold to engage with each other, pressing the protruding portion and the dented portion against each other to form the fastening angle bar, wherein the fastening angle bar has a first fastening portion, a second fastening portion defining an included angle with respect to the first fastening portion, and at least one angle reinforcing portion connected between the first fastening portion and the second fastening portion. A fastening angle bar is further provided.
Description
technical field [0001] The invention relates to stamping forming technology, in particular to a method for forming a fixed angle iron and the fixed angle iron. Background technique [0002] The conventional forming method usually cannot complete the fixed angle iron with the angle reinforcing part in one stamping. Therefore, the corner reinforcing part may not be formed smoothly, or the corner reinforcing part may be damaged, resulting in insufficient strength of the fixing angle iron. [0003] At this time, it must be completed with more engineering times, but the processing cost is wasted; or it is produced by casting or die-casting, and the time and cost of molds and machines are more. [0004] Therefore, the known forming method of the fixed angle iron and the fixed angle iron have disadvantages that still need to be improved. Contents of the invention [0005] In view of the above problems, the main purpose of the present invention is to provide a method for forming...
