In the process of long-term use of diamond drawing die, the die wall is subjected to strong friction and erosion of metal wire, which inevitably leads to wear phenomenon. The most common phenomenon is the annular groove (dent) at the entrance of wire rod in the working area.
After the ring groove appears in the diamond drawing die, the wear of the die hole is intensified because the small particles of the core material peeled off due to loosening on the ring groove are brought into the working area and sizing area of the die hole by the metal wire, playing the role of abrasive, while the wire entering the die hole aggravates the wear of the die hole like a grinding needle.
If the ring groove is not replaced in time for repair, the ring groove will continue to expand rapidly, making repair more difficult, and even cracks may appear in the deep part of the ring groove, making the drawing die completely broken and scrapped.
From the experience, it is very economical and cost-effective to formulate a set of standards, strengthen the daily maintenance and repair the drawing die frequently. Once there is any slight wear on the drawing die, it will take less time for the drawing die to return to the original polishing state, and the hole size of the drawing die has no obvious change.
If you want to make your diamond wire drawing die meet the requirements of quality, you must choose a reliable mold manufacturer. What kind of mold enterprise is reliable? Generally speaking, this kind of reliability also has a certain relationship with the scale of the enterprise. Only when the mold manufacturing enterprise that you choose has a certain scale, and you use the mold products they produce, you can feel reliable.
But why do you say that? On the one hand, when large-scale enterprises are engaged in production, they have the strength in this aspect. We all know that in the present industrial era, especially for products like wire drawing dies, it is impossible to produce them by hand. It is necessary to use professional wire drawing die production equipment, and the professional equipment must be in a large-scale enterprise Better introduce and update.
Therefore, large-scale wire drawing die manufacturers often have their own reliability in this respect. There is also one point, that is, some small manufacturers often do not have their own bottom line on the products when they are producing. Therefore, it is difficult to let people rest assured when using them. However, large-scale drawing die enterprises are different because they have more in their own enterprises So they don't dare to mess with the quality of their products. |
