Hydraulic hose assembly crimping operation guide: detailed explanation of methods and steps

2025-03-24


Hydraulic hose assembly is an important connecting component in the hydraulic system, and its crimping quality is directly related to the system's sealing, pressure resistance and service life. Correct crimping methods and standardized operating steps are the key to ensuring the performance of hydraulic hose assembly. In order to help you complete the crimping work efficiently, Liwang Fluid will introduce the crimping method and operating steps of hydraulic hose assembly in detail.

 

1. Preparation before crimping

 

Before crimping, first check the hose and joint to ensure that the hose is not damaged, aged, deformed or internally contaminated, and the specifications meet the use requirements. At the same time, check whether the joint surface is smooth, without cracks, rust or deformation, and ensure that it matches the hose specifications. Prepare tools such as crimping machine, measuring tools (such as vernier calipers), cleaning cloths and marking pens, and ensure that the crimping machine mold matches the specifications of the hose and joints. Finally, use a cleaning cloth to remove dust, oil and other impurities on the inner and outer walls of the hose and the inner and outer surfaces of the joints to ensure that no dirt remains.

 

 

2. Crimping operation steps

 

Step 1: Measurement, marking and installation

 

  • Use a vernier caliper to measure the outer diameter of the hose and the inner diameter of the connector to ensure that the two sizes match.
  • Mark the insertion depth of the connector on the hose to ensure that the length of the hose inserted into the connector meets the requirements (usually refer to the standard provided by the manufacturer). Inserting too shallow may result in an unsecured connection, and inserting too deep may affect the smooth flow of fluid.
  • Insert the hose into the connector to ensure that the hose fully reaches the marked insertion depth position, and check the alignment of the hose and the connector to avoid deflection.

 

Step 2: Adjust the crimping machine and crimp

 

  • According to the specifications of the hose and connector, adjust the pressure value and mold size of the crimping machine to ensure that the pressure of the crimping machine is uniform and avoid excessive or insufficient local pressure.
  • Put the assembled hose and connector into the crimping machine and start the equipment for crimping. During the crimping process, observe the connection between the hose and the connector to ensure that the crimping is uniform and without deformation.

 

Step 3: Check, clean and mark

 

  • After the crimping is completed, use a vernier caliper to measure the diameter of the crimping part to ensure that it meets the standard requirements, and check whether the connection between the hose and the joint is firm, without looseness, cracks or deformation.
  • Use a clean cloth to remove oil and impurities from the crimping part, and mark the crimping date, operator and crimping parameters on the hose for subsequent tracking and maintenance.

 

3. Precautions for crimping operation

 

During the crimping operation, it is necessary to select a suitable mold to ensure that it matches the specifications of the hose and the joint to avoid crimping failure; at the same time, strictly control the crimping force. Too much may cause damage to the hose or joint, and too little will affect the firmness of the connection. Regularly maintain the crimping equipment, check the hydraulic system, mold and pressure gauge, and ensure that the equipment is in good condition. Be sure to wear protective gloves and goggles during operation to prevent the hose or joint from popping out and causing injury.
