In order to ensure high-quality wire and effectively control the cost of wire drawing dies, attention should be paid to the following aspects:
1. Ensure smooth operation of wire drawing equipment. The wire drawing drums and wire guide wheels should be smooth and flexible, and their run-out tolerances should be strictly controlled. If it is found that the drum and guide wheel have worn grooves, they should be repaired in time. Good lubrication conditions are important conditions to ensure the surface quality of the wire and extend the life of the mold.
Always check the lubricating strength index to remove the copper powder and impurities in the lubricating oil so that it will not contaminate the equipment and die holes. If the lubrication fails, the lubrication system must be replaced and cleaned in time.
2. Reasonable collocation of molds is the key element to ensure the surface quality of the wire rod, control the dimensions accurately and consistently, reduce the wear of the wire drum and reduce the operating load of the equipment. For the sliding wire drawing machine, it is necessary to be familiar with the mechanical elongation of the equipment and choose the sliding coefficient reasonably, which is the first step of mold matching.
The hole type of the mold is selected according to the material of the wire to be drawn and the area reduction rate of each wire drawing. Generally speaking, the harder the wire is drawn, the smaller the compression angle of the mold and the longer the sizing area; and vice versa.
The area reduction rate of each wire drawing is also closely related to the compression angle of the corresponding mold. The compression angle should be adjusted appropriately according to the size reduction rate.
3. Effective maintenance and repair of molds is essential to reduce the cost of wire drawing. Due to the vibration of the wire, a slight ring abrasion first occurred in the area contacting the wire in the compression zone of the drawing die, and then continued to expand to the sizing area, resulting in a serious decrease in the surface quality of the wire and an increase in the wire size.
Not only that, severe wear and tear will cause lateral cracks (mainly in the drawing of soft filaments) or longitudinal cracks (mainly in the drawing of hard filaments), so that the drawing die is scrapped prematurely. Therefore, it is necessary to scientifically formulate wire drawing die maintenance specifications according to the type of wire to be drawn and the characteristics of the wire drawing machine.
Under normal circumstances, slight annular wear only needs to be polished to re-use, or a slightly enlarged diameter can also meet the drawing requirements. Excessive wear will greatly reduce the number of mold repairs, and even scrap, making the cost of wire drawing increased.
Why Is the Drawing Die the Basis of Drawing Die Quality?
The drawing die is a mold for manufacturing metal wire, which is processed from coarse to fine, and gradually reaches the required size. This special mold is what we call today. Next, we will learn more about the specific use of the product.
The products produced by the wire drawing die are widely used in the fields of TV radar, instrumentation and aerospace. Therefore, related products and various aluminum alloys are made of ordinary drawing dies, diamond drawing dies, and PCD wire drawing dies.
At the same time, natural diamond as a raw material has strong wear resistance and a long service life.
The pipe production process includes several process steps of lamination, die drawing and turning. The products are divided into different varieties and have a wide range of uses.
With the continuous development of society, the quality and efficiency of this product are also constantly improving.
There is room for development in the process of adaptation. In addition, in terms of material selection and processing technology, the product has more advantages.
Therefore, it has a wide range of uses and brings great help to our lives. The above drawing die is the basis of drawing quality.
What Are the Factors That Affect the Service Life of Wire Drawing Dies?
The service life of TC Dies will not only affect the production cost but also affect the stability of product quality and production efficiency.
What factors will affect the service life of the drawing die?
The Influence of the Production Materials on the Service Life of the Drawing Die
The mold material is one of the important factors that affect the service life of the mold. The performance of various mold materials in terms of hardness, corrosion resistance, wear resistance, fracture resistance, plastic deformation resistance, cold and hot fatigue resistance, etc. are very different, so the performance of the mold material should meet the specific conditions for the use of wire drawing dies. Otherwise, it will inevitably cause the early failure of the mold.
The Effect of the Hole Structure on the Service Life of the Drawing Die
With the improvement of modern drawing technology, traditional mold design concepts are changing. New concepts have been introduced into modern mold design. New “straight” drawing dies are increasingly replacing traditional “arc” drawing dies. After a series of improvements, the service life of the linear drawing die is 3-4 times higher than that of the arc drawing die, and it is especially suitable for high-speed drawing.
The Influence of the Production Process on the Service Life of the Drawing Die
During the manufacturing process of wire drawing dies, multiple processes such as forging, machining and heat treatment are required. If the manufacturing process of any process is unreasonable, it may be that the performance of the mold steel is reduced, structural defects are formed, and the hidden dangers of early mold failure are generated.
The Influence of Working Conditions on the Service Life of the Drawing Die
The processed materials with different thicknesses and different materials have a great influence on the service life of the drawing die. The greater the strength and thickness of the processed material, the greater the force the mold needs to withstand, and its service life is relatively low. If the processed material and the mold material have a greater affinity, there may be adhesion and wear with the mold during the molding process, resulting in a reduction in the service life of the mold.
The Influence of Reasonable Use and Maintenance of Wire Drawing Die on Its Life
During the use of the drawing die, it is reasonably used to maintain the drawing die and improve the repair level of the die. It is an important way to extend the service life of the die. In addition, good lubrication can effectively reduce friction and friction heat. Thereby reducing mold wear and improving the service life of wire drawing mold.
