Application

The hydraulic cylinder barrel is applicable to heavy-duty hydraulic cylinders for forging press machines.

Product Procedure

The mainstream manufacturing process for large forging press cylinder body adopts the full workflow: steel ingot → forging → heat treatment → rough machining → (welding) → finish machining → surface treatment → pressure testing and flaw detection.

The core technologies include forging, deep hole honing, and high-pressure sealing pressure testing, which ensure high strength, high precision and high reliability of the product.

Key Technical Points

Forging ratio ≥ 3 to ensure continuous flow lines and dense microstructure.

Precise temperature control in heat treatment to prevent quenching cracking and temper brittleness.

Honing is the core of precision, directly affecting sealing performance and service life.

Welding quality determines operational reliability; thick-wall welding shall avoid cracks and deformation.

Quality Inspection

Non-destructive Testing (NDT):

Internal: Ultrasonic Testing (UT), in accordance with GB/T 6402, no excessive defects allowed.
Surface: Magnetic Particle Testing (MT) / Penetrant Testing (PT), free of cracks and laps.

Feature

1.The operating conditions are harsh, with exposure to ultra-high pressure, heavy impact and alternating loads, requiring long-term continuous operation and stringent standards for fatigue resistance and leakage prevention.

2.It is manufactured from high-strength alloy steel via integral forging or forge-welded construction, featuring dense microstructure and excellent mechanical properties.

3.With large overall dimensions, heavy wall thickness and self-weight, it belongs to the category of long deep cylindrical thick-walled parts, demanding high structural rigidity.

4.It requires high machining precision, with strict tolerances of form and position as well as stringent surface finish requirements for inner bores and sealing surfaces.

5.The manufacturing process is sophisticated, involving forging, quenching and tempering, precision machining, non-destructive testing and high-pressure hydrostatic testing, with extremely high requirements for safety reliability and service life.
