| Reducing the consumption cost of diamond drawing die |
In the application of diamond drawing die, special attention should be paid to the following aspects:
1. Cleaning of diamond drawing die
The drawing die must be cleaned before use, because the impurities in the die hole not only scratch the surface of the wire material, but also cause the drawing die to produce grooves and even lead to the scrapping of the drawing die. Therefore, the drawing die must be cleaned by ultrasonic wave and dried by compressed air before use.
2. Cleaning of silk melt
The potassium nitrate or sodium nitrite solution used in the spinning head before drawing has a strong corrosive effect on the drawing die, which will damage the surface finish of the die. Therefore, it is necessary to clean the melt on the silk head before threading.
3. Reasonable installation and equipment maintenance of diamond drawing die
When installing the drawing die, it must be ensured that the center line of the die hole coincides with the drawing axis of the wire material. Otherwise, the wire will produce additional side pressure on the die wall, which makes the wear of the drawing die become asymmetric and uneven. In addition, improper installation and maintenance of the drawing equipment will make the drawing die under the working conditions of impact force, vibration or frequent start-up, which will cause uneven or fluctuating force on the drawing die and promote premature wear of the drawing die.
The quality of diamond drawing die has a direct impact on the quality and cost of products. Under the conditions of high precision, low cost and high efficiency, the quality of diamond drawing die can be produced in a longer time and more times.
With the continuous innovation of technology and technology, the wide use of new materials, the continuous update and reform of processing technology, the difference between the use and maintenance conditions and so on have different degrees of influence on the product quality of the drawing die. When drawing large diameter and hard materials, the quality of inlay sleeve is more important. It should be ensured that the die blank should be fixed firmly in the die sleeve under the actual drawing temperature It can effectively guarantee the service life of diamond drawing die.
According to the actual use conditions, the appropriate die sleeve material should be selected to meet the required drawing conditions and have a high elastic coefficient to resist the increase of blank size of the drawing die and the residual deformation of the die sleeve during drawing. It has good resistance to corrosion of lubricating materials used in the drawing production process, because the cost of the drawing die can reach the drawing cost Therefore, how to reduce the consumption cost of the drawing die and improve its service life is the primary problem that the metal wire rod production unit urgently needs to solve. |
