Reasons for the failure of the straight wire machine of straightening and cutting machine for steel wire straightening machine and its remedy
1. Even knife phenomenon. The reason is: the tension spring has small preload, the pressure roller is too large, and the feed trough resistance is large. Remedy: Increase the tightening force and eliminate the same method.
2. The square knife is ejected. The reason is: the traction force is too large and the resistance of the material in the feed trough is too large. Remedy: Reduce the pressure of the pressure roller, adjust the amount of rotation of the supporting column, improve the quality of the straightening, and increase the external force of the tension spring.
3. Adjust the size before falling from the feed slot. Cause: The support column is screwed in short. Remedy: Adjust the support column. 4. Reinforcement is not straight. Cause: The alignment block has a small offset. Remedy: Increase the offset.
5. Bending wire. Remedy method: adjust the straightening block angle, look at the straightener and the roller groove, cut off the assembly is in a straight line.
6. Broken wire occurs. Remedy: Adjust the angle of the straight block too large, cut the pressure spring on the assembly to become soft, the knife does not return, the pressure spring on the feed roller is too loose, the material is not good.
7. There is a short section. Remedy: Slide and the host tension spring too loose, adjust the tension spring. 8. The machine vibrates. Remedy: Adjust the balance of the straightening block.
9. Running wire. Exclusion method: pressure roller compression spring is too tight, the slide puller spring is too loose, the slide roller below the drag wire just roller is not in place, the slide does not slide.
10. The surface of the reinforcement is strained. Causes: Excessive pressure on the pressure roller, excessive offset of the straightening block, and damage to the straightening block. Remedy: Reduce the pressure, reduce the offset, and replace the straightening block.
