Talk about the cold drawing process and development prospects of cold drawn tubes
cold drawn tubeThe process has at least the following advantages. The mechanical properties of the material have been significantly improved. The second is to simplify the process and save man-hours and raw material investment. The third is to increase the service life of the product and increase the accuracy and roughness of the product. Due to the above advantages, the cold drawing process has been adopted by more and more manufacturers.
This kind of pipe not only has a dimensional accuracy of h8-h11, but also has a surface roughness of ra0.4-3.2um, and its mechanical strength is 20-35% higher than the raw material. It can be directly ground into an oil-type cylinder block and eliminates the need for intermediate tempering treatment, solving the problem that traditional methods cannot process thin-walled cylinder blocks.
The products produced by this process are wear-resistant and have long service life. It has been used in coal mine underground support and is expanding to petroleum production, metallurgical equipment, engineering machinery and automobile industries. As demand continues to increase, it has a broad product space. The use of cold drawing skills to produce hydraulic cylinder products, hydraulic cylinder products and engineering cylinder products has broad development space, and is also the future development direction for my country's products to become larger and enterprises to become stronger.
