Axle forgings saw more than expected mechanical design and practice of looking
Can be rotated around the spindle centerline. Because it saw in Figure 6, a spindle assembly seat hinge bar connected with the saw, sawing process, forging the blade cover for a relatively static translation, blocking most of the sawdust injection and cooling water. . Arm swing angle to ensure the highest position in the spindle center line, the forging can be adopted under the blade,[link widoczny dla zalogowanych], the spindle center line in the lowest position and the saw blade regrinding in diameter can be cut through to the most hours and beyond forging of about 15. m Er. Cut eight sharp teeth forging envelope in Cutting and always maintain the level of about l5. A 25. Angle, to facilitate the discharge of sawdust. On the sawing blade to the water spray cooling. Mobile saw the level of mobile devices is actually a position adjustable hydraulic cylinder, one end of the recoil, a termination Saw seat. Compact device is a mobile saw four piston cylinder, moving in place when the saw seat, the seat clamp saw him in bed, on credit to eliminate the gap, but also to prevent the movement saw cutting force in the chin Shao. Third,[link widoczny dla zalogowanych], the main stalk forging process conditions and equipment performance material for 4OA, final forging temperature is about 950 ℃, in the transport, feeding, aligning, although the temperature loss during compression, DA sawing can still ensure that more than 800 ℃ . High precision forging, forging diameter tolerance ± 1m dish, shoulder length stage position accuracy I/1000. Forging the surface of light cabinet. Which are conducive to clamping position. The duty cycle of cutting, sawing from forging entered to get out after the finish, including mobile saw base position adjustment, must be less than 3min. Performance of major equipment: blade diameter of 61ooo (most ~] x900) inm Saw blade feeding speed speed 1751r/min 4mm / s Pure 25s, according to the saw blade cut the elbow drive motor Y25OM asked a 455KW · 1480 ~ / min arm drive hydraulic cylinder hydraulic cylinder diameter 61oomm arm drive arm 320mm stroke hydraulic cylinder working pressure 6.3MPa drive hydraulic cylinder compression \Hydraulic Rainbow \m Series blade cooling consumption of 40m / h dropped out too hung wood bamboo mat jjI {● ostrich --- j · Weiluo _-~ ll125/30t casting crane structural characteristics of the gauge is too Yan t study by Man Nang chalky calendar. 1jl'1 recent years, I plant in Germany and Japan co-production, based on the design of {day I made a new type of casting 【crane. This combination of design and manufacture of 125730t casting factory cranes, cranes introduced some new features cast shoes. One, the lifting wing mandarin duck l, the arrangement of the main type of lifting mechanism features buildings by the main lifting mechanism of the hoist two separate devices (see Figure I) symmetrically arranged in the main car rack plane. Each device consists of motor, brake, reducer, the volume reduction device, the upper and lower pulleys and other components. Simple devices with volume reducer asked leaning coupling connection with the paper reel to help up and down} rope pulley in the news for winding, two low-speed device in the gear shaft coupling to join with the gear to ensure synchronization, and so that a sudden failure of the motor, the other TPC functions continue to work in a short time, so that the liquid suspension of the metal security barrier fell to the ground, each sector's net power drive motor according to the amount of lifting loads Cave 0. 66 times the selection. Figure 11. Motor 2. On the pulley 3. Reducer 4. Brakes 5. Small frame 6. Limit switch T. Volume 8 simple device. Coupling 9. From the open limit switch 10. After running the car body cone face, the difference is down to 4111m. Due to improved 3. Mourning the original design of forging more than expected when the cutting part is not supported. Practice has proved that the basic design is the hot saw success, health support, so the depth of more than eight saw a diameter of 2 / 3 after sawing yield, cutting ability, the device moves are in line with the tendency to teeth out, causing uneven end forgings. The field staff requirements. However, according to the situation also made some improvements to increase the part of the support of more than subjects, the above phenomenon is a significant change 1. As the saw blade, high speed spindle bearings had to choose good. Labyrinth seal tank selected, the original design and run with oil cooling cycle 4. End side of the forging mobile saw injustice than fixed 'slide, but a lot of oil out through the slot gap, so to the serious side of lubrication clamp estimated mobile device for mobile saw thrust greased. Practice has proved that,[link widoczny dla zalogowanych], even if the saw blade for work, insufficient axis, fixed-site staff to take temporary measures, bearing temperature rise does not exceed 60 ℃, grease and few outside the flow. Have effect in the future mobile devices can be increased hydraulic cylinder 2. The device is pulled aside on the face of the original claw diameter, the hydraulic fill up two or three two-pronged reform to do with the groove of the inclined plane, after cutting both ends of the cylindrical part of the forging method to improve. Length difference fOmm,[link widoczny dla zalogowanych], increase the period consistent with the cone shoulder garden
