Auto cold drawing machine is a type of equipment that enables the production of rods and wires that are used in various applications. The machine can help in reducing the diameter of the material while increasing the length, and can also be used to change the shape of the material. In addition, it can increase the strength of the material. For this reason, it is a must-have for manufacturers and fabricators who work with metal materials that require resizing, precision, and strict tolerance.
The process of cold drawing involves a continuous deformation of the material without heating. The process starts with a cylinder of the material, and then the die reduces its cross-sectional area. This is done by passing the material through a series of dies. As the material is drawn through each die, the volume of the material remains the same and its length elongates according to the new diameter.
While the material is drawn, it can develop metal fines. This is a result of the friction between the die and the material. These metal fines can be removed by cleaning, but they can also affect the quality of the material. As a result, it is important to use the right lubrication in the drawing process.
As the material is drawn, it can also undergo a significant amount of work hardening. This can have a positive impact on its strength, but it can also reduce the toughness of the material. The toughness can be improved by heat treatment after the drawing process is completed.
To accurately calculate the energy-power parameters of a drawing process, it is necessary to know the dependency of tensile and yield strength on cold working. These dependences vary for each alloy, and are also influenced by such technological parameters as drawing speed, the drawing route, and the half-angle of the drawing die. Therefore, it is necessary to determine the actual values of these indicators by experimental studies.
To do this, a laboratory drawing machine should be equipped with strain gauges and a data recorder. It is then possible to compare the calculated values with the measured ones and to verify the developed mathematical model. In addition, the experimental results should be compared with those of the calculation method. This will improve the accuracy of the developed mathematical model. The results of this research can be used to predict the energy consumption of a drawing process. This can then be used to make economical and ecological decisions. In addition, the results can be used to design a drawing machine that consumes less energy. This will lead to cost savings and reduced environmental damage. In addition, it will allow the use of higher-quality materials with a reduced cost. This will provide a better service to customers.
