In the automotive and internal combustion engine parts industry, piston rings are a large quantity and high quality parts. The types of piston ring waste include slag inclusions, pores, and sand inclusions. Such defects are related to many factors such as smelting, modeling materials, and processes. Whether the design of the gating system is reasonable or not involves the slag blocking effect, whether it is inhaling, gas circling, etc. According to the specific conditions of the production plant, we first analyzed the gating system and the casting process of the piston ring, and determined the method of water simulation to carry out the experiment.
The design of the gating system is closely related to the filling speed, and the speed of the filling speed influences the occurrence of sand filling, splashing, oxidation, etc., determines the good and bad slag blocking effect, and determines whether there is sand in the casting. Because of defects such as porosity and cold septa, a properly designed gating system has become the key to reducing casting waste and improving the quality of castings. Although computer simulations are used in a lot of ways, the water-simulating method makes it easier to observe the pouring process. It can be observed: (1) the gating system begins to fill the mold; (2) the pressure of each part of the gating system; (3) the gating system's suction and gas circumstance; (4) the slag blocking effect of the gating system; 5) The distribution of inclusions and pores in the cavity; (6) The filling process is stable.
In order for the experimental results to be used for production, it is necessary to ensure that the flow of fluid in the model is similar to the flow of liquid in the prototype, that is, the following conditions are satisfied: (1) similar flow media; (2) similar geometrical outline dimensions; (3) fluid physical properties Similar; (4) Similar initial conditions; (5) Similar qualitative criteria.
Hydraulic metal machine is mainly applicable to steel mills, recycling and processing industries and non-ferrous metal smelting industries. Hydraulic Baling Machine can squeeze all kinds of metal scrap (steel shaving, waste steel, waste aluminum, waste copper, waste stainless steel and scrap automobile waste, etc.) into cuboid, octagon, cylinder and other shapes of qualified charge, which can reduce the transportation and smelting cost, and improve the speed of furnace. It is mainly used for cold pressing under normal conditions for scrap metal scraps, scrap steel scraps, waste oil tank, disassembling car shell and other metal scraps with a thickness of less than 3mm. Cold pressed into blocks for easy storage and transportation or furnace.
Features:
1) Hydraulic drive, smooth and noiseless work, fast extrusion speed, large extrusion force, compact package block, not easy to be scattered.
2) high quality national standard steel plate with advanced welding technology to make the mechanical parts strong and durable, low failure rate, long service life.
3) the oil cylinder seal is imported glyd ring, good sealing performance, strong pressure resistance.
4) Convenient installation, small floor space, no foundation, foot, etc. Simple operation, detachable and PLC automatic mode.
5) Cold extrusion will not change the metal material and increase the utilization rate.
