Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: since both ends of the existing shell need to be processed, forging is relatively difficult, so casting is usually used for production, and the cost of casting is high

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] refer to figure 2 , is a forging process of a buffer housing disclosed by the present invention, comprising the following steps:

[0049] Step 1: Electroslag remelting, the steel ingot is placed in an electroslag furnace for remelting, so that the electroslag is remelted into an electroslag ingot. Electroslag remelted steel has high purity, low sulfur content, less non-metallic inclusions, smooth surface of steel ingot, clean, uniform and dense, uniform metallographic structure and chemical composition, so the structural strength of the material is higher;

[0050] Step 2: Billet opening, using electro-hydraulic hammer to forge the electro-slag ingot, heating the electro-slag ingot to above 800°C before billet opening, and forming a cylindrical round bar under the impact of the electro-hydraulic hammer;

[0051] Step 3: Cutting, the round bar is fir...

Abstract

The present invention relates to the technical field of buffer processing, in particular to a forging process of a buffer shell, comprising the following steps: Step 1: Electroslag remelting; Step 2: Blank opening; Step 3: Cutting; Step 4: Free Forging; step 5: forward die forging, carry out die forging of the end of the shell away from the mounting plate through the die forging die; step 6: reverse die forging, carry out die forging of the end of the shell mounting plate through the die forging die; step 7: Turning; step 8: drilling; step 9: spheroidizing annealing; step 10: quenching. The invention has the effects of reducing the forging difficulty of the shell through the unique process and the forging die, and reducing the production cost by using forging instead of casting to produce the shell.

Description

technical field [0001] The invention relates to the technical field of buffer processing, in particular to a forging process of a buffer shell and a forging die used in the process. Background technique [0002] Buffers used in railway vehicles are used to moderate longitudinal shocks and vibrations caused by changes in traction force of locomotives during operation or collisions between vehicles during starting, braking and shunting operations. The buffer has the function of dissipating the impact and vibration between vehicles, thereby reducing the damage to the structure of the vehicle body and the loaded goods. The working principle of the buffer is to moderate the impact force by compressing the elastic element, and at the same time absorb the impact energy by friction and damping during the deformation process of the elastic element. The buffer includes a shell and a buffer mechanism installed in the shell. [0003] Existing snubber housings (such as figure 1 shown)...
