Hardware parts processing manufacturers tell you that this is a processing method of hardware hexagonal screws, which is composed of a cold forging die and a round bar wire, which is characterized in that the round bar wire is taken, and the two ends are respectively extruded by four sets of cold forging dies. The step is to expand the wire in the round gourd cold forging die 1 to form a round gourd with a bevel and natural R angle, and then use the cold forging die 2 to squeeze the bevel of the round gourd of the die 1, and the material will be pressed to the cold forging die 2 of the six rounded corners are squeezed, the natural R angle becomes smaller, the inclined surface becomes flat, and the round melon becomes a similar hexagon with rounded corners and concave surface.
The hardware parts manufacturer tells you that, then, use the cold forging die 3 to continue the extrusion. The six guiding bevels of the cold forging die 3 are convex in the middle and concave on both sides. When the middle convex of the bevel is formed, it will be similar to the six hexagons. The material of the concave surface is squeezed in the six rounded directions, and the wire is completely filled with the cold forging die 3, the similar hexagon with rounded corners and concave surface becomes a standard hexagon with sharp corners, and finally the hexagonal surface is leveled again by the cold forging die 4 Then, a standard hexagonal screw is formed.
The hardware parts processing manufacturer tells you that by changing the processing method of the product, the production of the hardware hexagonal screw greatly reduces the consumption of raw materials, increases the service life of the cold forging die, effectively reduces the production cost of the product, and achieves the purpose of saving raw materials. .
