What are the common problems and solutions in the coil spring operation of the camless spring machine?

Posted by Admin
During the use of the coil spring of the camless spring machine, there are various uncertain factors such as mechanical reasons, improper operation, material problems, mold reasons, human factors, etc., which may cause the coil spring to be unstable. The output spring of the spring machine in the coil spring operation is unstable, and the product qualification rate will be greatly reduced, which will not only seriously waste enterprise resources, but also affect the progress and efficiency of social production. At the same time, it will also bring a certain loss of economic benefits to our own development. So, what are the common psychological development problems that students need in the operation of camless spring machine coil spring?

1. The wire feeding tension is unstable. During the operation of the spring machine, the unstable wire feeding tension will affect the stability of wire feeding. Such as: ① The wire feed frame is out of sync with the wire feeding speed or the brake device is out of order; ② The straightening roller (Pellin) is improperly adjusted or worn; ③ The roundness or wear of the wire feed roller is poor. Solutions to information management work: Check the tensioning mechanism or brake control system research institution of the wire feeding frame and restore the normal operation of the Chinese company; adjust or replace the automatic straightening roller; replace the wire feeding roller.

2. The surface of the spring is scratched. The wire scraping phenomenon occurs during the use of the spring machine, resulting in scratches on the surface of the spring. For example: ① The quality (defect) of the material itself; ② The surface of the straightening roller, wire feeding roller or wire plate is peeled off or stained by hard objects; ③ The auxiliary mandrel collapses; ④ The surface of the ejector pin is damaged, etc. Solutions to enterprise management work: replace different learning materials or materials that will have an important defect can be effectively removed; maintain economical pressure straightening rollers, wire feeding rollers or guide plate contact surface cleanliness or grinding technology analysis and treatment; replacement or repair mandrel; replace or repair ejector pin.
 
3. The coil diameter of the spring is not stable. Such as: ① There is internal stress in the material management, and the strength distribution is uneven; ② The material is not straightened, and the main material is under pressure during the wire feeding process; ③ The tension of the wire feeding is unstable. Solution: Check and replace the spring material; rearrange and arrange the wire, or adjust the wire to try again, or add a wire feeder, adjust the wire feeding direction; check and adjust the wire feeding tension.

4. The pitch is unstable and the free length varies greatly. For example: ①There is uneven distribution of internal stress and strength in material management, ② The pitch push rod can be set to move (by setting the pitch cam shape, origin and parameters are not in place), ③ The pitch push rod is not fixed properly. Solution: Check and replace the wire, reset the origin, check the position of the pitch push rod, and check whether the movement of the pitch push rod is set to loosen the lock.
 
5. The total number of rotations of the spring is unstable. For example: ① The quality of the material itself is poor, such as surface roughness; ② The precision error of the spring feed line is large; ③ The movement gap of the tool holder is large or the mold (such as "curve gauge") is poor, and the outer diameter of the spring is unstable, etc. There is no way to solve enterprise management: check and related materials and replace wires with good quality of work and life; check the spring machine's own technicians to design parameters and other performance, test the relative error of wire feeding accuracy, whether there is slipping between the rollers; check the tool holder Whether we can develop there is a certain gap, trim or replace the mold.
 
6. Improper connection at both ends of the spring. For example: ①The internal stress of the material science and technology enterprise itself has a great influence; ②The angle of the ejector rod is not adjusted properly; ③The shape, origin and parameters of the pitch cam structure can be set systematically. Bad etc. Solution: Check and replace the material; re-adjust the spring jack (also known as the pitch push rod); trim the shape of the pitch cam disc, and adjust the program instructions in the system.

7. Burrs on end of spring. For example: ①The gap between the cutter and the mandrel is too large; ②The rigid demand analysis of the cutter and the mandrel is insufficient, resulting in some looseness; There is a problem and it starts to crack or crack, etc. Solution: readjust the gap between the knife mandrel; check whether the plug iron and pad of the spring compressor are loose; use better materials (or higher process requirements) to repair or replace the knife mandrel.
