Problems solved by technology

[0006] 1. Since there is no billet-making equipment, the forgings that need to be billeted cannot be produced on the above-mentioned assembly line; therefore, if the workpiece requires billet making, it must be made by other equipment and then forged after the second heating;
[0007] 2. Forgings that need to be punched cannot be completed in one process, and must be reheated before punching;
[0008] 3. The types of products produced are greatly restricted, and the production cycle is long;
[0009] 4. Since most forgings are not completed in one process (that is, not completed after one heating), on the one hand, energy consumption is large, which increases production costs; on the other hand, the surface quality of forgings is poor

Embodiment 1

[0057] Such as figure 1 As shown, between the above-mentioned main heating equipment 1 and the friction press 6, an air hammer 3 is provided; between the above-mentioned air hammer 3 and the friction press 6, two punches are arranged, arranged in line order , are respectively punch one 4 and punch two 5; According to the assembly line order, in the rear of described friction press 6, establish two punches, be respectively punch three 7 and punch four 8.

[0058] Pneumatic Hammer 3 can be used to make blanks, thus increasing the types of products that can be produced. Since most forgings do not use the air hammer, but need to continuously use the first punch 4, the second punch 5 and the friction press 6, the air hammer 3 is arranged between the main heating equipment 1 and the first punch 4. In this way, in the case of most forging production, the forging production can be carried out continuously. If you need to use the air hammer 3, you can reverse it on the production lin...

Embodiment 2

[0062] The main heating device 1 of the present invention adopts a medium frequency induction heating device; the secondary heating device 2 is a fuel oil heating furnace.

[0063] The main heating equipment 1 is an intermediate frequency heating equipment with high heating efficiency and fast heating speed, and the heating and discharging speed can be adjusted according to production needs. The heating quality is stable and the material loss is less. The secondary heating device 2 is a fuel oil heating furnace with simple structure and low cost, and is suitable for secondary heating occasions that are not frequently used, and can be used at any time.

Embodiment 3

[0065] Punch one 4, punch two 5, punch three 7 and punch four 8 described in the present invention are double-column crank slider presses.

[0066] In the forging equipment assembly line provided by the present invention, the pressure of several processes using the punch press is smaller than that of die forging, so a double-column crank slider press can be used. Because the double-column crank slider press has a short stroke and a high stamping speed, it can improve production efficiency and meet the needs of some auxiliary work in forging, such as trimming, correction, and descaling.

Abstract

The invention discloses a forging device production line for a complex forged piece, which comprises heating devices, a forging device and a transfer device. The forging device is a friction press (6) and is arranged according to forging technology, the number of the heating devices is two, and the two heating devices are arranged at two sides of the transfer device of the production line in parallel, wherein one heating device is a main heating device (1), and the other heating device is a double-heating device (2). The invention also provides corresponding forging production technology. The invention adopts a technical proposal to heat the shaped forged piece twice so as to meet the requirement of the forged piece with special request, and solves the repair problem of part of unqualified forged pieces at the same time.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing technology and equipment thereof, and relates to thermal processing of mechanical parts, more specifically, the invention relates to a forging equipment assembly line of complex forgings. The invention also relates to the forging production process adopted by the forging equipment assembly line. Background technique [0002] At present, the forging production equipment assembly lines of most domestic mechanical parts are arranged in the following order: [0003] Heating equipment—→Friction press—→Punch [0004] Its advantages are: 1. Small investment in equipment; 2. Small footprint. [0005] However, there are also many disadvantages in the arrangement of the above-mentioned equipment, such as: [0006] 1. Since there is no billet-making equipment, the forgings that need to be billeted cannot be produced on the above-mentioned assembly line; therefore, if the workpiece require...
