Auto cold drawing machine is a type of machine that can be used for the cold deformation of metal wires or rods. The cold drawing process allows for the control of the size of the finished product and can also help to change the shape of the material, which is especially useful for metals such as copper or aluminum that need to be shaped in order to fit into specific applications.

This process is different from hot rolling or forging because it involves a much lower temperature than these other methods. This helps to prevent the alloys from work hardening during the deformation process, which is helpful for keeping the strength of the materials up to a high level and also helps to keep the size of the material down. The process can be used to make the materials smaller and it can also be used to change the shape of the materials, such as transforming round bars into square ones.

One of the most important parts of this process is determining how to calculate the power parameters for the process. This is because the stability of the drawing process, the efficiency of the work and the validity of the choice of drawing equipment when designing production lines all depend on how accurately this is done. To determine this, a mathematical model of the drawing process must be built. It can then be used to compare the calculated and experimental power parameters of the drawing process.

During the cold drawing process, the die squeezes and deforms the material. The die is usually made from some sort of alloy that can be changed to fit the application for the final product. For example, a round bar can be drawn into a square or hexagonal bar by using the correct die.

In addition to the change in the plastic properties of the material, the draw force is also affected by the degree of work hardening that occurs during the deformation process. The draw force can also be influenced by the geometry of the die and the amount of technological lubricant applied to the deformation zone. This can cause a change in the friction coefficient at the metal-metal contact. This is why it is important to know how to calculate the draw force in advance.

Horenco is proud to offer a line of top-of-the-line swaging, cold drawing and straightening machinery that can take your company to the next level. This includes the HS model series which is designed to streamline the entire precision drawing process for various types of metal tubes and bars. This chain-type machine can be used for a wide range of alloys and materials including brass, mild steel and other symmetrical metals that require re-sizing and strict tolerances.

This system uses drawing capstans that are independently driven and electronically controlled to minimize slip while the front and back pull are working together. The resulting accuracy of the drawing machine is very high, allowing for the production of higher-quality products and greater material savings. The HS models also feature a head-press set that replaces the swaging process for increased efficiency and reduced cost.
