Embodiment Construction

[0025] A kind of processing method of high wire diameter ratio T iron of the present invention, comprises the following steps:

[0026] (1) Calculate and select rods of reasonable diameter according to the requirements of T iron and cut them into blanks. The calculation is based on the weight and size of T iron, and usually a rod with a larger diameter is selected as the blank.

[0027] (2) Put the blank into the lower die installed in the circular shear heading machine, first use a punch to extrude the positioning foot of the workpiece, and then use the positioning foot to position, so that the material bar is stuck in the lower die, and a punch returns After that, convert it into a second punch and punch it quickly to form a mushroom head shape.

[0028] (3) Putting the headed blank obtained in step (2) into a flattening die for flattening treatment.

[0029] (4) The flattened blank obtained in step (3) is put into a forming die for forming.

[0030] The high wire-diameter...

Abstract

The invention discloses a machining method and a machining die for T iron with the high wire diameter ratio, and belongs to the technical field of T iron machining. The machining method is the new T iron machining technology which is high in production efficiency and stable in product quality. The machining method comprises the steps that (1), according to the requirements of T iron, bars with reasonable diameters are calculated, selected and cut into blanks; (2) the blanks are placed into a lower die installed on a circular-snip heading machine, positioning pins of a workpiece are squeezed out by a first trimming die at first, then the positioning pins are used for positioning, bar materials are clamped into the lower die, the first trimming is changed into a second trimming die to rapidly beat after the first trimming die is retreated, and a shape of an agaric head is formed; (3) blanks processed through heading and obtained in the step (2) are placed into a flattening die to be flattened; (4) the flattened blanks obtained in the step (3) are placed into a forming die, and T iron is formed. The machining die comprises the heading combination die, the flattening die and the forming die, and is used for machining the T iron with the high wire diameter ratio.

Description

technical field [0001] The present invention relates to a T iron processing technology, more particularly, it relates to a high wire diameter ratio T iron processing method. The invention also relates to a tooling tool for carrying out the above method. Background technique [0002] In the traditional T-iron processing technology, four sets of molds are used for high-wire-diameter ratio T-iron products with a wire-diameter ratio greater than 4:1. , each process requires a dedicated mold. This traditional process has the disadvantages of many processes and high production cost, and there is a need for improvement. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a T iron processing method with high production efficiency and stable product quality, aiming at the above-mentioned deficiencies of the prior art. [0004] Another technical problem to be solved by the present invention is to provide a processing die for...
