What are the common problems of lathe parts?
Common problems and causes of lathe parts processing are detailed as follows:
1. Burr: During stamping or trimming, there is no residual material, and burr will occur under the section of steel plate. Cross sections are used for reference. When the height of burr is more than 0.2mm, burr will occur. Iron powder will damage the mold and produce bumps.
2. Concave and concave: The surface of the material is abnormally convex or concave, which is caused by the incorporation of foreign matters (iron filings, dust).
3. Drum printing: the cleaning roller or the paper feeding roller is caused by the attachment of foreign matters (at a fixed interval). Generally, foreign matters printed on the paper can be removed.
4. Sliding printing: occurs when the roller slides, stops suddenly or accelerates.
5. Crushing of coiled materials may wrinkle at the edge: the guide roller of uncoiling line may wrinkle the gap between the guide rollers on the mold due to unwinding of the mold feed port.
6. Scratches: the main cause of scratches on parts. There are sharp scratches or metal dust falling into the mold. The preventive measure is to repair the scratches on the mold and remove the metal dust.
7. Bottom crack: The main reason for the bottom crack of this part is that the material is poor plasticizing or pressed too tightly on the mold compression ring. The preventive measure is to replace the plastic or loosen the presser foot ring.
8. The side wall has wrinkles: the main reason for the wrinkles on the side wall of the part is that the thickness of the material is not enough (less than the minimum allowable thickness), or when the upper and lower materials are eccentric, the lower mold is installed, thus creating a large gap on one side. The clearance is very small. The preventive measure is to replace the material
And readjust the die.
