Forging process analysis The intermediate flange part of the forging is a drive shaft gear blank. In order to ensure better mechanical properties of the forged parts, the first solution, because the intermediate flange has a large size, the rod ends are small in diameter and lengthened. It is easy to produce end intrusion and interlayer, so when adopting this scheme, the process cutting head needs to be added to make it meet the minimum length of lengthening A≥ long and the length of the blank becomes longer. Although the raw materials can be fully utilized, the equipment is required to be more Big trip. However, under the current equipment situation, only the second option can be selected. Since there is no special requirement for the forging ratio of the part, the selection of the blank is mainly considered to be advantageous for the lengthening, and the high-diameter ratio at the time of the upsetting is satisfied, so that the forging ratio of the intermediate flange is set to 3. 5. The process is: heating ? Pull the long head? Heat? Process Analysis During the entire forging process, upsetting is the primary forming process. The deformation resistance of metal during forging is related to various factors such as heating temperature and friction pressure. The relationship between the yield stress and the heating temperature in the forging temperature range. It can be seen that when solidified at 1000 to 1 200 ° C, it should be alternately and evenly operated until the upper and lower casings are in close contact. The connection box is in place and protected: the connection box is buried in the pit, and the bottom of the hole is made to be flat and wide, and the connection box is placed smoothly into the bottom of the pit, and the cable should be kept straight from the box. The backfilled sand or soft soil is 200 mm above the box, and then the corresponding protective cement shield is placed and the joint pit is filled. Care should be taken to prohibit backfilling of hard objects such as large stones. The splicing box is embedded and hardened. Quality control cable connection is an important part of cable construction. Its quality is directly related to the quality of the project and the reliability and stability of the interlocking equipment. It also directly affects the safety of driving. In order to effectively ensure the construction quality, The following quality measures are formulated.
