Forging die for rotary forging of forging steel brake disc of high-speed train

Abstract

The invention discloses a forging die for rotary forging of a forging steel brake disc of a high-speed train. The forging die structurally comprises a lower die, a rotary forging cavity, an upper die,a male die and a ring filling device. The forging die has the beneficial effects that a sound transmission mechanism is utilized, and the propagation of sound wave in the medium is utilized, so thatwhen cast steel liquid is filled in a rotary forging manner, the cast steel liquid can be subjected to vibration treatment, when there is a gap that cannot to be filled, the cast steel liquid is uniformly dispersed and flowed under the action of vibration, and incomplete filling that reduces the self plasticity is avoided; and through the utilization of an arranged anti-warping structure, the flattening and pressurizing effect on the upper edge corner of the brake disc is performed, so that the phenomenon of warping at the radiating ribs of a finished product is effectively avoided.

Description

technical field [0001] The invention relates to the field of brake disc processing, more precisely, it relates to a forging die used for swing rolling of forged steel brake discs of high-speed trains. Background technique [0002] As a delivery tool that can run continuously at high speed, high-speed trains are used by more and more people as the first choice for travel. Because they run at high speeds, it is necessary to use wear-resistant and less thermal creep parts on their braking parts. Parts, and when processing and producing them, it is especially necessary to strictly control the selection of the parts, so as to avoid unnecessary accidents caused by the influence of braking parts during operation. [0003] In the processing of parts, when processing the brake disc, due to the heat dissipation ribs provided on the outer edge of the brake disc, according to the size of the brake disc required by the high-speed train, the placement distance of the heat dissipation ribs...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a forging mold for forging steel brake disc swing rollers of high-speed trains, so as to solve the heat dissipation ribs provided on the outer edge of the brake disc swing rolls in the prior art, According to the size of the brake disc required by the high-speed train, the placement distance of the cooling ribs also increases (decreases) with each other, so when processing, it is easy to appear that the distance between the cooling ribs is small Due to the small gap and the characteristics of the molten steel, the gap cannot be completely filled. At the same time, after it is filled and manufactured, the surface and corners of the heat dissipation rib of the brake disc are rough and rough. It has rough surface such as barbs, which will weaken the self-compression resistance of the brake disc when it is in operation, reduce its ductility, and cause defects in the phenomenon of fracture when it is put into use
