The friction press is a kind of friction screw press driven by the way, also known as double disc friction press, metal forging press production workshop is to use the contact drive flywheel and the friction disc, and with the relative movement of the working principle of screw and nut. Due to the use of universal, and has advantages of structure, installation, operation and auxiliary equipment is simple and cheap, so in machinery manufacturing, automobile, tractor and aviation industry in stamping workshop, forging workshop and forging workshop are widely used, also can be in blanking. The friction press is widely used in building materials machinery, ceramic tile, refractory products and dry pressing production.
Copper sleeve, also called copper bearing, needs to be lubricated with oil bearings. It is made of various kinds of copper alloy and used for lubrication of machine parts. With a large variety of heavy machinery, it is an important component of the machinery. The main materials are 1, ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to manufacture moderate load and speed work of the Bush, gear, worm gear and other wear-resistant parts. 2, ZCuSn10P1 is a typical tin bronze. Its hardness and wear resistance are very high. It can be used to make heavy load, high speed and high temperature work, parts which are strongly rubbed, such as connecting rod, copper sleeve, gear, worm gear and so on. 3, ZCuAl9Mn2, ZCuAl9Fe4, aluminum bronze with high strength, high compactness, stable chemical properties. Often used for valves, worm gears, nuts, pipe fittings, etc.. 4, ZCuZn25Al6Fe3Mn3 high strength aluminum brass, the highest strength in the special brass. With high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used for casting heavy machinery with high load and wear resistance
