In our parts processing industry in the process of precision parts processing, will have the presence of the noise and the noise will not only interfere with the normal work of the technical staff, but also a kind of noise pollution; So is car radiator cap there any way to reduce the occurrence of the noise? By the model of the below small make up to tell you:
1, civilized production: gear transmission noise has more than 30% of the causes from the burr and knocked wounded, some in front of the gear box assembly precision parts processing factory, remove burrs and knocked wounded, is a passive way.
2, from the mechanical principle of noise control measures:
1) to improve mechanical equipment structure, the application of new materials to noise reduction, with the development of materials science and technology, various new material, with some larger internal friction, high damping alloy, high strength plastic production machine parts has become a reality. 2) improve the quality of precision parts processing and assembly, from the mechanical principle of noise control mainly depends on the development and production of assembly, usually before the factory noise reduction measures. Later in DIN screw plug the process of operation and maintenance, to avoid the light load and overload of mechanical equipment, choose good lubricating oil, can reduce the noise.
For efficient metal cutting processing, they determine the processing time, tool life and processing quality, economic and efficient processing method must be reasonably choose the cutting condition.
Cutting condition of three elements: the cutting speed, feed and depth as a direct result of tool damage. With the increase of cutting speed, the tip temperature rise, will produce mechanical, chemical, thermal wear. If the cutting speed increased by 20%, half the knives' service life will be shortened. Feed conditions and tool wear behind the relationship within the scope of the tiny, but feeding, cutting temperature rise, wear behind. The tool is less than the influence of cutting speed. Cutting speed and feed, cutting depth has no effect on cutting tools. The choice of optimum processing condition was conducted according to these factors. Regular stable wear to life is the ideal condition.
But in actual work, decided to processing conditions, the need to study according to the actual situation. Difficult-to-machine materials such as stainless steel and heat resisting alloy can use coolant, also can use high rigid blade.
From the point of view of traditional processing technology, combined with the existing measuring tool, can undertake mold polishing before processing lubrication with open slot, at the same time can also design a kind of clamping is milled, the mechanical parts processing, can let the balance screw and clamping fixture is processed at the same time, milled and small gap between the workpiece, which not only improve the rigidity of the open slot reduced the risk of deformation, also can make the balance screw to suit the requirements of precision.
Sine rules to measure the introduction of sine bar is taper Angle or lever table with Magnetic Drain Plug calibration work, relationship between block gauge and trigonometric function of sine a precision measuring tool, by two precise cylinder and a precise working plane body composition, when machining in the belt Angle of workpieces can be precise positioning, when making machinery parts processing, put it in homework tablet on sine bar, flat by sine bar across the baffle locates on the workpiece, the final size required for sine bar height and measured workpiece size, the sum of measurement in this way, can strictly control precision parts of shape and size tolerance, can locate precisely the location of the error, and at the same time can easily draw the workpiece precision data.
