Mechanical servo main transmission device of large-tonnage high-speed fine blanking machine

Abstract

The invention relates to a mechanical servo main transmission device of a large-tonnage high-speed fine blanking machine. The mechanical servo main transmission device comprises a main slide block, an auxiliary slide block and a drive mechanism, wherein the main slide block and the auxiliary slide block can only linearly move, and the drive mechanism can drive the main slide block and the auxiliary slide block to move at the same time. The drive mechanism comprises a servo motor, a lead screw connected with an output shaft of the servo motor, a slide block arranged on the lead screw in a sleeving manner and can only linearly move, a connection rod L1, a connection rod L2, a connection rod L3, a connection rod L4 and a connection rod L5. One end of the connection rod L1, one end of the connection rod L2 and one end of the connection rod L3 are hinged to the same point. The other end of the connection rod L1 and the other end of the connection rod L3 are hinged to the slide block and the main slide block correspondingly. The other end of the connection rod L2 is a fixed hinge point. One end of the connection rod L4 and the connection rod L2 are fixed into a whole, and the other end of the connection rod L4 is hinged to one end of the connection rod L5, and the other end of the connection rod L5 is hinged to the auxiliary slide block. The movement directions of the main slide block and the auxiliary slide block are opposite all the time. The device is good in dynamic characteristic, reasonable in arrangement, small in vibration, high in machining precision and capable of balancing inertia force.

Description

technical field [0001] The invention belongs to the field of fine blanking machines, and in particular relates to a mechanical servo main transmission device of a large-tonnage high-speed fine blanking machine. Background technique [0002] High-speed fine blanking machine is an efficient equipment for parts processing and precision forming. It is mainly used in high-tech fields such as aerospace, automobiles, power generation equipment, information, and home appliances. Its high-efficiency and high-precision processing has unique advantages. One of the key technologies of the high-precision fine blanking machine is the design and manufacture of the main drive. At present, the main drive of the press mostly uses a high-speed hydraulic punch system. As long as the high-speed hydraulic punch system is turned on, the motor will run non-stop, idling consumption There will be more electric energy, and there is still a problem of leakage in the hydraulic system, which will cause p...

One of the key technologies of the high-precision fine blanking machine is the design and manufacture of the main drive. At present, the main drive of the press mostly uses a high-speed hydraulic punch system. As long as the high-speed hydraulic punch system is turned on, the motor will run non-stop, idling consumption There will be more electric energy, and there is still a problem of leakage in the hydraulic system, which will cause pollution during use. When the machine tool is working, the noise generated by the high-speed operation of the hydraulic system is also relatively large
