In the process of highway construction, a large number of construction machinery and construction machinery combinations are needed. As the technical conditions gradually deteriorate in the course of their use, engine power is reduced, fuel consumption is increased, exhaust gas is excessively exceeded, gaps of transmission components are increased, and operation mechanisms do not operate. The working device generates an error. This is mainly due to the wear of the parts and the structure of the parts, the processing quality of the materials, the working conditions (climate and construction environment), the quality of the fuel and lubricant materials, the rationality of use, the operation methods during construction, the configuration of the machines, and the technical maintenance With the quality of repairs, etc., the following are analyzed. Wear and damage of construction machinery parts During the use of machinery, wear occurs due to friction between parts. Under normal conditions, the wear process of the part is divided into D stages. The first stage is the running-in phase. Before machining, the surface of the machined part is rough and the wear is great. For example, during the running-in period of a newly purchased mechanical vehicle, during this period, as the time increases, the working surface of the component wears gradually, and the fitting gap between the components reaches the initial gap. The second stage is the normal working phase of the part. After the fittings are worn out, the surface of the parts is smooth and smooth, and the clearance meets the design standard. During the use of the machine, the amount of wear between the mating parts is small, and the gap between the mating parts grows slowly. The third phase is the accidental damage phase. During the use of the machine, due to the increased clearance, the impact load will be generated, the lubrication conditions of the parts will be deteriorated, and the rapid increase in wear may damage the parts and cause mechanical accidents. Mechanical wear Mechanical wear is caused by the mutual friction between the surfaces of the parts. Although the surface of the parts is machined, it cannot be absolutely flat. When the parts are in contact with each other, they can be easily embedded in each other. As the parts move, the raised metal particles continuously fall off. When the fit clearance increases to a certain extent, the parts will be increased due to the impact load, and the lubrication conditions will be damaged and the wear will continue to increase.
Compared with the castings, metal after forging processing can improve its organizational structure and mechanical properties. Casting organization after forging method of thermal deformation due to metal deformation and recrystallization, make original bulky dendrite and columnar grain to grain is fine and uniform axial recrystallization organization, make the ingot in the original segregation, porosity, porosity, slag compaction and welded, such as its organization become more closely, plasticity and mechanical properties of the metal.
The mechanical properties of castings is lower than forging mechanical properties with the same material. In addition, the metal forging process can guarantee the continuity of fibrous tissue, the forging of fibrous tissue and forging appearance consistent, metal flow is complete, can guarantee the parts with good mechanical properties and long service life with precision die forging, cold extrusion, extrusion temperature and other process of forging, is incomparable by casting
Forging is a metal pressure, through the shape of the plastic deformation shape requirements or suitable compression force. This kind of typical power by using a hammer or pressure. Forging process built fine granular structure, and improve the physical properties of metal. In parts of practical use, a proper design can make the grain flow in the direction of main stress. Casting is to use all kinds of casting method for metal forming objects, namely the good liquid metal smelting, casting, injection, inhaled or other casting method into the prepared mold, after cooling the shakeout, cleaning and post-processing, etc., of a certain shape, size and properties of objects.
There are many different kinds of forging processes available, however they can be grouped into three main classes:
Drawn out: length increases, cross-section decreases
Upset: length decreases, cross-section increases
Squeezed in closed compression dies: produces multidirectional flow
Common forging processes include: roll forging, swaging, cogging, open-die forging, impression-die forging, press forging, automatic hot forging and upsetting
Steel Forging Parts are very popular in forging process. We can supply big range of such steel forging parts.
