With the continuous development of science and technology, in order to meet the special requirements of the performance of machine parts, some new materials with high strength, high toughness and high wear resistance are emerging. However, t....
Figure 12-1 shows: Schematic diagram of the front support part sof the motorcycle side cover, Material Q215 steel, Thickness 1.5mm. The annual production capacity is 500,000 pieces, and the stamping process plan is required.....
Chapter One Parts Introduction Parts analysis description 1. Parts shape and general requirements As shown in Figure 1-1, the material is stainless steel, the material thickness is 0.5mm, and the dimensional accuracy of the workpiece must m....
The cutting method of the swarfs breaker and the main cutting edge are commonly used in the external oblique types, parallel types, and internal oblique types (see Figure 10).....
The swarf formed during the cutting process will have a higher hardness and a significantly lower plasticity and toughness due to the relatively large plastic deformation. This phenomenon is called cold work hardening. After cold hardening, the swarf ....
Whether the tool swarf breaking is reliable or not has a major impact on normal production and operator safety. In the cutting process, the swarf of the swarf will splash and hurt people, and it is easy to damage the machine tool; Long strips of swarf....
1.Turning slender shaft geometry accuracy and surface quality requirements are high. Conventional processing methods are used to clamp the workpiece between the main shaft and the tailstock. There is no flexibility at both ends. Under the influence of....
