Gas Cylinder Production Process—Head Blanking

Gas Cylinder Production Process Step 1: Head Blanking

Blanking of gas cylinder heads (i.e., cutting) is a crucial step in the manufacturing process of liquefied gas cylinders, involving cutting metal sheets into shapes and sizes suitable for making heads. It is also one of the concerns of many customers:

Material Preparation Selection of Metal Sheets:

Choose metal sheets of appropriate thickness and quality, usually high-strength steel or aluminum alloy. Inspection and Cleaning: Inspect the sheets for defects and clean the surface to ensure there is no oil, dust, or rust.

Design and Layout CAD Design:

Carefully confirm customer requirements and determine the dimensions and shapes for blanking. Layout Optimization: Secondary optimization based on sheet dimensions and head design to reduce material waste.

Cutting CNC Cutting Machine:

Use CNC cutting machines for cutting to ensure high precision and efficiency. 

Inspection and Correction Dimensional Inspection:

Use measuring tools (such as calipers, thickness gauges, etc.) to check if the blanked dimensions meet the design requirements. Correction: If dimensional deviations or irregular edges are found, make necessary corrections to ensure the semi-finished blanks meet quality standards.

Marking and Storage Marking:

Mark each semi-finished head with numbers, specifications, and production dates as per customer requirements for post-sales tracking and management. Storage: Properly store the blanked semi-finished heads to avoid damage and deformation, awaiting subsequent stamping and welding processes.

Quality Control Quality Inspection:

Conduct strict quality inspections, including dimensional accuracy, edge quality, etc., to ensure each semi-finished head meets standards.

Stamping and Forming Stamping:

Feed the blanked semi-finished heads into stamping machines for forming, creating arc-shaped heads that meet design requirements. Welding: Weld the formed heads to the cylinder body to complete the main structural part of the gas cylinder.

Blanking is a fundamental and critical step in the head manufacturing process, directly affecting the quality of subsequent liquefied gas cylinder forming and welding. Therefore, each step needs to be strictly controlled to ensure the safety and reliability of the final product, delivering a satisfactory product to customers.
