Large mechanical processing technology in the operation with the corresponding processing method processing machinery spare parts for production, so that we can make the shape, size and properties meet the corresponding standard, mainly including rough machining
, finish precision machining, assembly, inspection and packaging process, as long as we ensure that every process, to make product more standardized, reasonable, ensure that it conforms to the relevant standards.
So in the process of machining, we need to know what a large mechanical processing technology?
1, remove the parts on the scale, at the same time, the appearance of the processed parts should not appear defects such as scratches and bruises.
2, in the assembly of the heavy, should ensure that its shape, length, size, temperature, comply with relevant standards, at the same time guarantee the sealing of the whole system, so as not to affect the assembly of the hydraulic system.
3, in the process of assembly, to avoid the parts a knock against, scratch or rust, etc. , affect the large-scale machinery processing, makes the impact and damage from the performance of the product and let our work cannot continue to normal.
Large precision machining characteristics after quenched and tempered treatment have good comprehensive mechanical properties, low temperature impact toughness, and low notch sensitivity, good hardenability.
When oil cooling can get higher strength, water-cooled parts easy to crack.
Tempered or quenched and tempered after cutting workability is good, but the weldability isn't good, easy to crack.
After quenching and middle temperature tempering used in the manufacture of heavy and medium speed movement of the mechanical parts, such as oil pump rotor, slider, gear, shaft, etc.
After quenching and low temperature tempering, used in the manufacture of overload, low impact and abrasion resistance of mechanical parts, such as worm, shaft, shaft, etc.
Carbonitriding place namely after manufacture large size, high low-temperature impact toughness of the transmission parts, such as axle, gear, etc.
1 of mechanical processing equipment of the production safety requirements.
Mechanical processing equipment, should meet the safety requirements of environmental protection of materials, are not allowed to use harmful to human body and without security inspection of the material.
The overall structure of the mechanical processing equipment must level off is smooth, no sharp edges and sharp.
Easy to cause accident of mechanical processing equipment shall be completely fixed or semi-fixed airtight cover.
Mechanical or electrical barrier should be used in mechanical processing equipment, interlock and hands off the device.
Automatic or semi-automatic loading discharging device.
Should be assembly automatic or manual emergency stop device.
