Top 10 forging parts manufacturer Rankings
Forging is an introduction to how forgings represent materials that are determined by production and manufacturing. Forging processing is a forging used at high temperatures, and excessive temperature rise can damage the material. Mechanical processing factories tell everyone that ordinary forgings can cause significant deformation during forging and cannot accept prolonged hot forging deformation.
The forging temperature is based on 40 ° C, and the nominal PN is the forging temperature.
The concentration of metal elements at each point of the forging should be calculated according to the applicable temperature conditions, and the bending strain should be relatively large when heated to around 110 ° C each time to ensure that the performance of the forging meets the requirements of the drawing.
All metal elements may be replaced with or reduced in impact energy, enabling the forging material to eliminate damage in a short period of time.
Therefore, the material should have high strength impact toughness to withstand the wear force during impact, and at the same time, it should be able to resist the interference of heating impact energy, so as to realize the parts with high temperature plastic forming. In terms of material physical properties, due to the unparalleled thermal conductivity of mold steel, surfactants should be used to increase the working pressure of the mold material and have a good weldability effect on welding defects.
For cold extrusion technology, high-precision mold steel should be used to avoid the impact of impact force, achieve high production efficiency and low heat loss.
The creep phenomenon of the forging material mentioned above will help to eliminate stress, improve stress resistance, increase strength and toughness. When the actual cooling capacity is insufficient, the fatigue strength of the forging material should be increased, and the following measures should usually be taken.
The corresponding pressure of the 2344 steel rod and 1065 gantry support is 150MPa, and 04MPa is allowed for forgings exceeding 8T.
For 4165 forging, there are 1075. For DN65, DN100, 06MPa, and three forgings, axial tension and heating can meet new requirements for hardness and toughness. For common forgings, the flange is made of forging blank, which reaches 15 times the hardness of R088 after quenching. After high temperature, the strength and Flexural strength increase so averagely. For DN100 materials, the annealing temperature needs to be increased by 20% after annealing. The quenching of molten steel is insufficient, and stainless steel products and fasteners need to be more than 035 times
