Forging process of rotary drilling mast

Abstract

The invention discloses a forging process of a rotary drilling mast. The forging process comprises the following steps of heating a rod-shaped steel piece material block, the heated rod-shaped steel piece blocks are placed in a die of a forging machine, carrying out pre-forging and blank making by a forging press along the axis direction of the rod-shaped material block to obtain a cake-shaped and solid prefabricated drill mast blank, punching the center of the prefabricated drill mast blank from a punch to obtain a prefabricated drill mast blank with a through hole; continuously heating the prefabricated drill mast blank, and carrying out multiple expansion on the through hole of the prefabricated drill mast blank with the through hole by a punch on a forging machine; carrying out pressing operation on the prefabricated drill mast subjected to multiple reaming in the step under a forging machine to obtain a pre-formed blank; and the pre-formed blank is heated, and the heated pre-formed blank is subjected to final forging by a forging machine to obtain the rotary drilling mast forging. The forging process is used for improving the utilization rate of the steel, the forging precision is improved, the structural strength is high, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery forging, in particular to a forging process of a rotary drilling mast. Background technique [0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size; the drill mast is one of the important parts of the rotary drill, and the existing In the technology, the drill mast will be damaged for a long time. Once the drill mast is damaged, the damage to the rotary drill is self-evident, and it will cause safety hazards to the entire rotary drill. The utilization rate is not high and the structural strength is not enough. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned problems in the prior art, the present invention provides a forging process for a rotary drilling mast, which improves the utilization rate of steel, improves forging prec...

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes; the drill mast is one of the important components of rotary drilling, and the existing In technology, the drill mast will be damaged after a long time of use. Once the drill mast is damaged, it is self-evident that it will be destructive to the rotary drilling drill and cause a safety hazard to the entire rotary drilling drill. Moreover, the raw materials in the forging of the existing drill mast Defects of low utilization rate and insufficient structural strength
