Product details: fire jack support tools

The jack support tool for fire fighting is an important auxiliary tool designed for the support of fire fighting equipment, which is widely used in fire rescue and emergency. This hardware tool main function is to provide a strong and stable support point to ensure the safety and efficiency of fire appliances in rescue operations. In order to meet the requirements of high strength and high reliability in the field of fire protection, the product has been designed and manufactured using strict processes and high-quality materials.

Production Technology And Process

1. Material selection and preparation

Steel pipe: cold-rolled steel pipe is preferred, with high strength and good ductility.

Material requirements:  Material surface is flat, no cracks, in line with GB/T 700 or ASTM A36 and other relevant standards.

 

2. Processing technology

• Stamping:The steel plate is pressed by hydraulic press, and the base and side support of the support are made.
• The stamping die needs to have high precision to ensure the consistency of the dimensions of the parts and the error is controlled within ± 0.5mm.
• Laser cutting:High-precision laser cutting of steel pipes is used to cut support holes or stiffeners in complex structural shapes.

The advantage of laser cutting is that the cutting speed is fast, the incision is smooth, and no additional grinding is required.

• Welding:The parts are spliced together by gas shielded welding (MIG/TIG welding) to form a complete support structure.

Non-destructive testing must be performed on the welding parts to ensure that there are no pores or cracks in the welds and that the welding strength meets the high safety requirements of fire fighting tools.

• Surface treatment:Spraying: Spraying anti-corrosion coating on the surface of the bracket to enhance anti-rust perfor.Galvanizing:  Hot dip galvanizing treatment to provide long-term oxidation protection for connectors. The coating thickness is controlled at 40-80 μm to ensure the durability of the product in harsh environments.

3. Quality inspection

• Dimensional inspection:  Use a coordinate measuring instrument to detect the dimensional accuracy of key components to ensure that the overall structure meets the requirements of the design drawings.
•  Load test:  Perform compressive and bending tests on the support to verify its bearing capacity under high strength environments.
• Surface inspection:  Through visual and equipment inspection, confirm that the surface is free of paint stripping, bubbles or uneven coating.

Performance Requirement

High strength and load capacity:

Products must withstand extremely high dynamic and static loads and maintain long-term stability. The welding strength should meet the design requirements to ensure that there is no fracture or deformation during use.

Corrosion resistance:

The combination of surface galvanizing and spraying process makes the bracket still able to be used for a long time in a humid and corrosive environment without corrosion or performance attenuation.

Durability:

The support must have good impact resistance and fatigue resistance to meet the needs of high frequency use.

Environmental adaptability:

The tool must be able to maintain stable performance under extreme temperatures, such as high temperatures in a fire scenario, and have good aging resistance.

Product Advantage

Strong reliability: The combination of optimized design and high-quality processing technology makes the support extremely stable.

Environmental protection and durability:  Spraying and galvanized surface treatment to ensure long product life and environmentally friendly.

This fire jack support tool is one of the indispensable equipment in the fire industry with its precision processing technology, excellent performance and high reliability.
