Hydraulic rescue tools are widely used in emergency scenarios such as firefighting, traffic accident rescue, earthquake rescue, etc. With their high-pressure drive, strong demolition force and convenient operation, they have become an indispensable equipment for rescue teams. The manufacturing process of such tools involves multiple high-precision process links to ensure that the products have high strength, high durability and reliability. This article will analyze the manufacturing process of hydraulic rescue tools in detail, from the selection of raw materials to the final product inspection.
High-quality hydraulic rescue tools usually use high-strength alloy steel, aluminum alloy or composite materials to ensure that the tools will not deform or break under high-pressure working conditions.
Main material requirements:
Blades and shearing parts: high-strength alloy steel is used, with excellent wear resistance and impact resistance.
Fuselage and bracket: mostly use aviation-grade aluminum alloy or high-strength steel, taking into account both lightweight and strength requirements.
Hydraulic system components: such as pistons, seals, etc., need to use high-pressure and corrosion-resistant materials (such as high-density polymers or special steels).
Processing process:
Laser cutting: Precisely cut the metal raw materials to form the required component shape.
CNC precision machining: Use CNC machine tools (CNC) for high-precision turning, milling, drilling and other processing to ensure accurate dimensions.
Heat treatment: Hardening, tempering and other heat treatment processes are performed on key components to improve hardness and durability.
The hydraulic system is the core component of hydraulic rescue tools and determines the power output and work efficiency of the tools.
Hydraulic pump and cylinder manufacturing:
Cylinder processing: Use high-precision honing machines to process the inner wall to reduce friction and improve sealing.
Piston rod manufacturing: After turning, heat treatment, and chrome plating, it improves wear resistance and corrosion resistance.
Seal assembly: Use high-quality rubber or polytetrafluoroethylene (PTFE) seals to ensure no leakage.
Hydraulic valve and piping system:
Hydraulic valve assembly: High-precision assembly of hydraulic valve blocks to ensure accurate fluid control and rapid response.
High-pressure hose connection: Use high-pressure and high-temperature resistant rubber or metal hoses to ensure stable transmission of hydraulic fluid under high-pressure environment.
Assembly process:
Main frame assembly: Preliminary assembly of the processed fuselage, bracket and hydraulic system.
Shear blade installation: Adjust the blade gap to ensure uniform shear force distribution.
Expansion arm/demolition claw debugging: Ensure that the expansion, shearing and clamping functions meet the design standards.
Welding and surface treatment:
Welding process: Use robot welding or manual argon arc welding to ensure a stable structure.
Surface coating: Spray anti-corrosion coating or oxidation treatment to improve wear resistance and corrosion resistance.
After manufacturing, hydraulic rescue tools must undergo strict quality inspection and performance testing to ensure that they meet international safety standards (such as NFPA, CE, ISO 9001, etc.).
Testing process:
Pressure test: Test the stability and safety of the hydraulic system under extreme pressure.
Shear/expansion force test: Measure the maximum shearing capacity of the shear blade and simulate the demolition of different materials (such as metal pipes, car frames, etc.).
Durability test: Conduct continuous high-intensity work tests to ensure that the tool maintains stable performance under long-term use.
Safety test: Evaluate the safety of operation, such as the function of the pressure relief valve, the sensitivity of the operating button, etc.
The products that pass the test will be finally cleaned, packaged, and prepared for delivery.
Packing requirements:
High-strength shockproof packaging is used to ensure that it is not damaged during transportation.
Operation manuals, maintenance guides and certificates of conformity are included.
According to customer needs, portable tool boxes or professional transport boxes of different specifications can be customized.
The manufacturing of hydraulic rescue tools involves multiple precision process links, from material selection, hydraulic system manufacturing, mechanical structure assembly to strict quality inspection, each step is crucial. With the continuous advancement of manufacturing technology, intelligent and lightweight hydraulic rescue tools will become the trend of future development, improve rescue efficiency and ensure operational safety.
