Forging: We can provide forged ring, open-die forging, forged shaft, forged bush, forged shape, drop forging, precision forging, hot-pressed part, upset forging, hot-upset part, forging casting, forged disc, perforated disc.Press Brake Tools/Die for bending machine, Press brake die, die and blade, die and mold, die and mould, mold and knives, tools for bending machine, die for bending machineThe press brake tools of CNC bending machine has a wide application with different requirement. It is widely used in sheet metal bendings, such as construction, Kitchenware, automobile, aircraft manufacturing, light industry, shipbuilding, container, elevator, railway vehicles, and other industries.Bending machine works as the picture.The CNC bending machine uses a mold (general or special mold) to bend a cold metal sheet into a workpiece of various geometric cross-section shapes. It is a sheet metal forming machine designed for cold rolling sheet metal processing.So the tools of bending machine need high hardness and accuracy so that it can have a wide range of possible bending materials, apart from that the upper and lower molds must fit well and firmly.Firstly need to choose the right raw materials of metal. T10,55SICR,42CRMO, and other good steel, producing with forging process, CNC machining, Heat treatment, and accurate grinding.42CRMO is a normal raw material in this field, "42CRMO" is the mark name in China, and it also called 42CrMo4, SCM440, 4140, 1.7225. Usually, 10-15mm thicker than finished tools, and the knife is 5mm thicker. This working allowance is enough to reach tolerance requirements.Forging process, repeatedly forging. We called it cold forging or drop hammer forging. Heat Treatmentquenching + tempering + 860 °C Oil quenching + 390°C TemperingThe role of heat treatment is to improve the mechanical properties of the material, eliminate residual stress and improve the machinability of the metal. Hardness can reach 47- 52+/-2 HRC. Bending edge used high-frequency heat treatment to make sure high rigidity and long tool working life. (The HRC is available by changing the temperature, based on your special needs on that)
After that, we have a strict quality control system, ISD9001:2008, also we have in house testing
Apart from that, we need the tools delivered to our clients in good condition, and we always willing to find the best solution according to our client's target and weather of their local.
