So far, no commercially available an authoritative books or detailed information about how to adjust the spring forming outer diameter, and the operation of the knowledge and skills most comes from practice experience, which can be a very good learning and guide future work. Interpretation in the process of debugging spring machine, how to adjust the spring forming outside? Mechanical technology application and computer system program is very important.

  Debugging spring machine process involves the application of mechanical process:

  Installation and blade 1, mandrel mill. For the double pole CNC spring machine, core shaft to cutting edge effect of spring, usually the core shaft called core cutter or the auxiliary core. The grinding process is simple and the principle is: the core shaft arc ear should be less than the diameter of the spring ring, but not too small, otherwise it will spring forming cut generated when the flat head phenomenon; at the same time, grasp good cutter spacing and core shaft, the gap can not be too big.

  And 2, the top rod operation regulation. The outside diameter of the spring is composed of a push rod to control, in general, the top rod is curve by controlling the forming position and angle to control the outside diameter of the spring. The push rod of the adjusting principle: on the push rod to move to the core axis when the diameter of the spring is smaller, and vice versa; under the push rod to move to the core axis diameter becomes large, otherwise small.

  Control, adjustment of 3 wire feed length and the number of laps. The wire length and number of turns depends on the choice of the number of teeth. For spring machine incomplete gear feeding, the number of teeth of the incomplete gear and its control of spring length principle, the formula is: the number of teeth (Z) of length L = spring (mm) / feed coefficient, expansion spring length (L) = (spring outside the the wire diameter) * ∏ * total number of coils.

  The computer system program instruction set, adjusting machine master or technical personnel through the computer hand wheel button operation in the process of debugging spring machine, operation and modify the attempt for various parameters instruction spring forming, to confirm the program of instructions and memory to save to. The return to zero after the operation, enable the automatic production of key features, can be mass production. The technical support from Kaichuang spring machine: http://www.kcmcnc.com/en/.
