Hardware processing accessories are more and more. In many machines, many processing factories can be used more and more, like cranes, or forklifts, or cranes, or some gold locks in life, keys, etc.. The parts of locomotive repair these, can be applied to, this is a point, now the specifications of hardware processing, as well as processing materials are different, according to the customer's needs, processing dimensions are also different.

(1) In designing the structural shape of the parts, the hardware stamping parts adopt a complex and reasonable appearance and its combination. At the same time, the minimum number of machining surfaces and the minimum processing area should be used.

(2) The selection of methods for preparing rough materials in rational machine manufacturing can indirectly apply materials, casting, forging, stamping and welding. The choice of rough is related to the detailed consumption technical conditions, and generally depends on the consumption volume, data function, and processing ability.

(3) The requirements of the metal stamping forming function are conducive to the Advancement of stamping deformation and the quality of the parts. The data should have good plasticity, small Quqiang ratio, large directionality coefficient of plate thickness, small directionality coefficient of plate stereo, and small ratio of yield strength to elastic modulus of data. The process does not require data to have a good plasticity, but it has a certain plasticity.

(4) Proper manufacturing accuracy and appearance roughness. The cost of hardware stamping will be added with the improvement of accuracy, especially in the case of higher accuracy, this addition is extremely obvious. Therefore, when there is no abundant basis, it should not be pursued as high precision. Similarly, the appearance roughness of the metal stamping parts should also be based on the practical requirements of the appearance to make appropriate rules.
