Description

Vertical pipe forging equipment

The new type is a vertical pipe forging equipment, especially a vertical pipe forging equipment including a first forging equipment and a second forging equipment.

A common method of exposing a mold for aluminum alloy pipe fittings:

Step A. First, process the hollow cylindrical raw material to form the blank, and extend the blank along the axis to form a first end surface, a second end surface opposite to the first end surface along the axis, and a connecting first end surface and the second end surface An original length is formed between the outer peripheral surface, the first end surface and the second end surface.

Step B: Homogeneous annealing of the blank material. The blank material is heated to 410~510°C and then cooled with the furnace. The temperature in the furnace drops by 10°C per hour and is discharged when it is cooled to 200~160°C.

Step C, detecting the hardness value of the Rockwell hardness scale HRF of the blank material is 60±5 degrees.

Step D, immersing the blank material in a lubricating fluid tank, the total free acidity of the lubricating fluid contained in the lubricating fluid tank is 40-50% by weight, the working temperature is 80-100°C, and the immersion time is predetermined.

Step E. Perform forging and drawing operations. Place the blank material impregnated with lubricating fluid in the forging die, and operate the forging tap to approach the forging die, so that the blank material is subjected to the forging and drawing action of the forging tap and the forging die. The finished product is formed into a hollow tube shape along the axis, and has a first side surface intersecting the axis, a second side surface opposite to the first side surface along the axial direction, an outer ring surface connecting the first side surface and the second side surface, and Contrary to the outer ring surface and surrounding the circumference of the inner ring surface that can form an inner hole, the first side surface is connected to An extension length greater than the original length is formed between the second side surfaces.

Through the above method, the finished product can be produced by cold forging operation, which can save energy, reduce die consumption and reduce overall manufacturing cost; however, the conventional technology only exposes the forging die, forging tap and forging die single processing of the blank material in a single pass. The length and surface of the blank material in the secondary processing are limited, and only simple processing can be performed.

This creation discloses a vertical pipe forging equipment, including a first forging and drawing equipment and a second forging and drawing equipment. The first forging and drawing equipment includes a first forging and drawing die and a first forging and drawing die corresponding to the first forging and drawing die. Tap, one end of the first forging tap has a first convex portion of equal diameter, and the second forging device includes a second forging die and a second forging tap corresponding to the second forging die. One end of the forging tap has a second protrusion formed by a tapered section extending an equal diameter section. The minimum diameter of the tapered section is equal to the diameter of the same diameter section. The length and diameter of a protruding part are equal; with the above structure, a tube is forged and drawn through the first forging and drawing equipment and the second forging and drawing equipment in order to complete a vertical pipe.

With the above structure, this creation discloses a vertical pipe forging equipment that provides two-stage forging. The pipe can be subjected to two-stage forging operations through the first forging equipment and the second forging equipment to obtain a two-stage forging operation. In addition to extending the length of the deformed vertical pipe product, the outer peripheral surface of the vertical pipe product also has a better thinness.

1 to 5, this creation discloses a vertical pipe forging equipment, including a first forging equipment 10 and a second forging equipment 20, by sequentially passing a pipe 30 through the first forging equipment 10 and the The second forging and drawing equipment 20 performs the forging and drawing operation to complete a finished vertical pipe 32.

Figures 1 and 2 disclose the first forging device 10, the first forging device 10 includes a first forging die 11 and a first forging tap 12 corresponding to the first forging die 11, the first forging die 11 One end of the tap 12 has a first protrusion 121 with an equal diameter, and the length of the first forging tap 12 is greater than the length of the first forging drawing die 11.

Continuing to refer to FIG. 2 and in conjunction with FIG. 1, the first forging tap 12 is pressed down against the pipe 30, the top of the first forging tap 12 is provided with a first abutting portion 122, and the bottom surface of the first abutting portion 122 is pressed against the pipe. On the top surface of 30, after the first forging tap 12 is pressurized, the pipe 30 is deformed in a first stage toward an end different from the first forging tap 12.

Figures 3 to 5 disclose the second forging device 20. The second forging device 20 includes a second forging die 21 and a second forging tap 22 corresponding to the second forging die 21. The length of the tap 22 is greater than the length of the second forging die 21. One end of the second forging tap 22 has a second convex portion 221, and the second convex portion 221 is formed by a tapered section 222 extending an equal diameter section 223 The minimum diameter of the tapered section 222 is equal to the diameter of the diameter sections 223, and the length and diameter of the diameter section 223 and the first protrusion 121 are equal.
