Auto cold drawing machine is a chain-type machinery that can be used to process a variety of metal tubes and pipes that need to be resized and precision-drawn to certain specifications. It can also be used to reshape the ends of metal bars and tubes, making them more usable in various industrial applications. Horenco has recently introduced a line of state-of-the-art swaging, cold drawing and straightening machines that will make the work of manufacturers and fabricators much easier.
This machine works by using a hydraulic push pointer to clamp the workpiece and direct it against the drawing die, which reduces the diameter of the bar. The entire process is automated, which eliminates the need for manual swaging and greatly streamlines the cold drawing process. The HS model series from HOREN can draw round, hexagonal, square and rectangular bars from a wide range of materials including brass and mild steel. After the cold drawing process, the bars are automatically carried via discharging arms to designated collection racks next to the drawbench.
During the cold drawing process, alloys undergo a type of deformation known as “work hardening.” While this is beneficial in terms of increasing the tensile strength of the metal, it can cause the toughness to decrease. The impact of this on the mechanical properties can be reduced by proper heat treatment.
In addition, the effect of cold drawing on the plastic properties of the material is dependent on a number of technological parameters such as the drawing speed, the drawing route and the die angle. The calculation of these effects allows the development of an energy-power mathematical model for wire drawing.
A key aspect of the design of a new machine is to determine what the maximum drawing force will be and what the minimum power consumption should be. These values are then used to optimize the mechanical and electrical parts of the machine. In order to calculate the maximum possible drawing forces, it is necessary to measure the strains that occur in the workpiece during the drawing process. This information is then used to construct a model that will predict the performance of the machine.
In order to improve the accuracy of this model, it is necessary to use a high-quality strain gauge that can reliably measure the stress that occurs in the workpiece during the drawing process. It is also necessary to determine the relationship between the pressure and the friction coefficient in order to determine the correct drawing speed. The results of the modeling can then be compared with the experimental data to provide an accurate prediction of the performance of the new machine. The results will also help to optimize the technology of lubrication in the deformation zone. This will further improve the quality of the product and the efficiency of the machine.
