Automatic terminal machine operation process

1. Turn on the power switch of the automatic terminal machine, and the power indicator light is on. Pay attention to the abnormal noise inside and outside the machine. If there is a suspension, ask the mechanic to determine if it needs to be repaired.

2. Selecting the knife to be installed: It is operated by the designated personnel. Before the tool is loaded, it must be manually compared with the selected blade. If the comparison is correct, the knife can be loaded. After the tool is completed, the hand test must be used. Firstly, the automatic terminal machine is closed. Power, press the touch button, use the special wrench to shake the main driven wheel, so that the terminal presses the press stroke to the maximum. If the hand is not moving, consider whether the pressure is too large or other problems, check and debug to OK. Before each operation, check each locking screw and confirm that it is not loose.

3. Loading: Install the automatic terminal machine that needs to be hit. Use the hexagonal wrench to adjust the feeding platen so that the automatic terminal machine can pass easily. Visually check whether the feeding position is suitable. If not, adjust it and use the inner hexagon plate. Loosen the feeder lock screw, turn the adjustment lever to adjust it to the best condition, then lock the feeder lock screw to start the operation.

4. Test tension: After adjusting the machine OK, take the waste wire and test it, and carry out the tensile test. The main reference value is shown in the “Tursion Test Comparison Table”. The specific operation method is as follows. Press the pull test to reset the zero key to zero. The terminal wire is clamped and tested. If the measured tension is not within the standard range, the mechanic should re-adjust until the standard value is reached.

5, trial production 10PCS to send IPQC for the first piece of confirmation, inspection OK, in order to mass production, the operator must self-test the terminal is not covered with rubber, hanging neck and other bad, and once every 1 hour terminal Machine pull test. After the production is completed, the good products and waste products are sorted out, and the environmental sanitation around the fully automatic terminal machine is cleaned.

 

Machining accuracy of fully automatic terminal parts

(1) Dimensional accuracy. It refers to the extent to which the actual size of the part is close to the ideal size, as indicated by common dimensional tolerances. According to the national standard GB/T 1800. 1 - 2009, the standard tolerance is divided into 20 grades, namely IT01, ITO, 171 YIT18. IT indicates standard tolerance, and Arabic numerals indicate tolerance level. The larger the number, the larger the tolerance value is. The smaller the dimensional accuracy is. 1TOI---IT13 is used for the matching size. The commonly used matching dimensional tolerance is below IT5; IT14-ITIS Used for non-mating dimensions.

(2) Fully automatic terminal machine shape accuracy. It refers to the extent to which the actual shape of the part is close to the ideal shape. Shape tolerances include straightness, flatness, resilience, columnarity, line profile, and face profile.

(3) Stereo tolerances. It refers to the extent to which the actual wall between the surface, axis or plane of symmetry of the part is close to the ideal position. Terminal machine position tolerances include parallelism, verticality, inclination, position, concentricity, symmetry, mouth bounce and full bounce.
