Preparation work
Select terminals and wires: Choose the appropriate tubular terminals and wires according to the actual needs. Ensure that the specifications of the terminals match the diameter and type of the wires1.
Inspect the machine: Check whether the tubular terminal machine is in good condition, including whether the power supply is normal, whether the components are loose, and whether the pressing dies are intact.
Prepare tools: Prepare necessary tools such as pliers and wire cutters.
Machine setting
Adjust the pressure: Set the appropriate crimping pressure according to the thickness and material of the terminals and wires. Generally, this can be adjusted through a pressure regulating knob or a setting in the control panel. The pressure should be sufficient to ensure a secure crimp but not too much to avoid damaging the terminals or wires13.
Set the stripping length: If the machine has a wire stripping function, set the length of the wire insulation to be stripped according to the requirements of the terminal connection. This is usually adjusted by setting a specific value in the machine's settings. Make sure the stripping length is suitable for the terminal to ensure a good connection1.
Choose the die: Select the corresponding pressing die according to the shape and size of the tubular terminal. Different dies are used for different terminal specifications to ensure a proper fit and crimping effect.
Operation process
Load the terminals: Put the tubular terminals into the terminal feeder or the designated loading position of the machine. Some machines may use a vibrating plate feeder to automatically supply terminals, while others may require manual loading one by one.
Insert the wires: Insert the prepared wires into the terminal through the wire inlet of the machine. Make sure the wires are inserted fully and correctly into the terminal cavity.
Start the machine: Turn on the power switch of the tubular terminal machine and start the crimping operation. The machine will automatically strip the wire insulation (if set), insert the wire into the terminal, and then crimp the terminal to the wire with the set pressure and for the set time12.
Inspect the crimping quality: After crimping, visually inspect the crimped joint to check if the terminal is firmly connected to the wire, whether there is any deformation or damage to the terminal, and whether the wire is securely held. You can also use a 拉力测试仪 (tensile tester) to test the tensile strength of the crimped joint to ensure it meets the required standards.
Repeat the process: Continuously load terminals and wires and repeat the above steps to complete the crimping of multiple terminals.
After-operation work
Turn off the power: After all the crimping work is completed, turn off the power switch of the tubular terminal machine to save energy and ensure safety2.
Clean and maintain the machine: Clean the machine surface and remove any debris or scraps of wire and terminal. Regularly lubricate the moving parts of the machine according to the manufacturer's instructions to ensure smooth operation and prolong the service life of the machine.
Store the machine properly: If the machine is not going to be used for a long time, store it in a dry and dust-free place to prevent corrosion and damage.
