Auto Cold Drawing Machine
Auto cold drawing machine is a type of metal working machinery that resizes tubes and bars to specific sizes and shapes. The process can be either wet or dry, depending on the type of lubricant used. In wet drawing, water or oil-based lubricants are used. In dry drawing, dry lubes are used. The machine is capable of drawing a variety of materials, including brass, mild steel, and alloys. It can also draw round, hexagonal, and square bars. The bars produced from this machine are then annealed for further strength and appearance.
The biggest function of a cold drawing machine is to control the size of the material. Manufacturers can control the size of the material through different dies that are shaped differently. The squeezing action of the die deforms the material and reduces its diameter. This will create a more streamlined and narrower bar. Manufacturers can also shape the cross section of the material through different dies. The resulting bars can have any shape and length, as long as they are thinner than the original round rod.
Aside from controlling the size of the material, cold drawing also removes impurities on the surface of the alloy. The pressure of the die causes friction, and this will cause the material to rub off the surface of the alloy. This will give the material a polished or bright finish. This will make the rods easier to handle and use in manufacturing products.
When a rod is drawn, its tensile and yield strength decrease. This is caused by a combination of the loss in tensile strength and the reduction in plastic properties. The change in tensile and yield strength is influenced by technological parameters of the drawing process such as drawing speed, drawing route, and the number of draw stages. It is therefore important to know the equations for changing tensile and yield strength during cold drawing of different alloys.
To minimize the losses during drawing, manufacturers can use a calamine stripping machine to remove a coating of iron oxide on the rods. This will make it easier for the rods to enter the drawing machines and will increase the production capacity of the cold drawing machine. Another way to minimize the losses is by reducing the number of draw stages. This will also save on energy and improve the product quality. This can be done by using a cold drawing machine with a lower capacity and by lowering the temperature of the dies. This will also help to improve the accuracy of the drawing force. This will prevent the machine from overheating and causing damage to the rods. This will result in higher quality products and greater profit for the company. This will lead to more satisfied customers. In addition, the cost of using a machine with a low capacity will be cheaper than purchasing a larger one. This will save money in the long run and allow the business to compete with other companies.
