1. Hammer Body (Impact Cylinder): Preferably made of high-strength alloy steel (such as 42CrMo), with tensile strength ≥1080MPa and yield strength ≥930MPa. Tempering heat treatment is applied to improve toughness and prevent breakage. 2. Piston: Made of alloy structural steel (such as 20CrNi2Mo), with surface carburizing and quenching treatment, hardness of HRC58-62, ensuring wear resistance […]

1. Material Preparation and Forging – The hammer body, piston, and tamping rod blanks are forged using the die forging process to ensure continuous metal flow and avoid casting defects; cutting is performed using CNC flame cutting machines or plasma cutters, with dimensional errors ≤ ±0.5mm. – Forging temperature is controlled at 1100-1200℃, followed by

1. Pre-assembly Preparation – Clean all components thoroughly, remove oil stains and metal shavings; check seals, bearings, and other wear-prone parts for integrity. Do not use deformed or damaged components. – Prepare specialized assembly tools (torque wrench, press machine, alignment pins) and avoid using brute force to strike. 2. Core Assembly Steps (1) Install the
