Embodiment Construction

[0018] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0019] Please refer to Figure 1-3 , the T iron hemming process steps include:

[0020] (1) In the first closed cavity 11 of an indenter mold 1 , the head of an iron column 2 is hemmed and pressed to form a semi-finished product with a trapezoidal head.

[0021] (2) In the second closed cavity 31 of a flattening mold 3, the trapezoidal head of the semi-finished product formed in the above step (1) is hemmed and pressed to form a semi-finished product 4 with a straight head.

[0022] (3) In the third closed cavity 51 of a forming mold 5 , the inline head of the semi-finished product formed in the above step (2) is hemmed and pressed to form the finished product 6 .

[0023] Among them, the indenter mold 1 in step (1) includes a first upper template 12, an indenter upper mold 13, a first lower template 14, an indenter low...

Abstract

The invention discloses a T iron hemming process. The T iron hemming process comprises the following steps of (1) performing hemming pressing on the head of an iron column in a first closed cavity of a head pressing die so as to obtain a semi-finished product with a trapezoidal head; (2) performing hemming pressing on the trapezoidal head of the semi-finished product formed in the step (1) in a second closed cavity of a flattening die so as to obtain a semi-finished product with an I-shaped head; and (3) performing hemming pressing on the I-shaped head of the semi-finished product formed in the step (2) in a third closed cavity of a forming die so as to obtain a finished product. By using the T iron hemming process, the production efficiency is improved, the production cycle is shortened, the machining cost is reduced, and raw materials are saved.

Description

technical field [0001] The invention relates to a T iron forming process, in particular to a T iron edge wrapping process. Background technique [0002] Ordinary T-iron hemming process due to uneven feeding and process eccentricity when forging T-iron products with a diameter of 80 or more, makes the outer circle eccentricity and cylindricity of T-iron fail to meet the requirements, so it usually needs to be lathe Processing can make the product meet the standard. Although the method of lathe processing can make the outer circle of the product achieve higher precision, it will waste a lot of manpower and material resources in machining, and the efficiency is low, the material waste is serious, and the production circumference is long. Contents of the invention [0003] The purpose of the present invention is to provide a T-iron hemming process, which solves the problems of low efficiency, serious waste of materials and long production perimeter. [0004] In order to achie...
