Problems solved by technology
Because there is no reducer, the selected AC servo motor has large specifications, large size and high cost
In addition, the transmission method of the ball screw is point contact between the ball and the nut and the screw, so the bearing capacity is small, resulting in a large size of the selected ball screw and high cost, which makes the ball screw with large specifications and high nominal pressure. cannot be used on the bending machine
This kind of AC servo motor driven by the ball screw cannot meet the requirements of large-sized, high-nominal pressure bending machines
In addition, the servo control performance of these bending machines is poor, the assembly is complicated, it is not easy to disassemble, and the degree of modularization is low

The invention relates to an electromagnetic driving servo bending machine with a planetary pin roller screw for transmission. The electromagnetic driving servo bending machine with the planetary pin roller screw for transmission comprises two servo motors which are symmetrically arranged and externally connected with gear reducers. The output shafts of the gear reducers are connected with the input end of a planetary gear reducing mechanism. The output end of the planetary gear reducing mechanism is connected with the upper end of a transmission shaft. The transmission shaft is perpendicularly fixed in a machine body through a thrust bearing, an upper end cover and a lower end cover. The lower end of the transmission shaft is connected with the planetary pin roller screw which is externally connected with a nut. The nut is installed on a sliding block which is driven by the planetary pin roller screw to move back and forth to finish bending work. The electromagnetic driving servo bending machine with the planetary pin roller screw for transmission has the advantages of being high in bearing capacity, high in operation precision, good in servo controlling capacity and the like.
Description
Technical field [0001] The invention belongs to the technical field of bending machine manufacturing, and specifically relates to an electromagnetic drive servo bending machine using planetary roller screw transmission. Background technique [0002] Bending machine is a machine that can bend thin plates. It uses simple molds to press metal sheets into the required geometric shapes. It can be widely used in electrical appliances, electronics, metal structures, instruments, meters, and daily hardware. , Construction and decoration industries. Bending machines can be divided into manual bending machines, hydraulic bending machines and CNC bending machines. The manual bending machine has low accuracy, low automation, and poor control performance, which limits its application. The oil circuit of the hydraulic bending machine is complicated, and the oil needs to be supplemented after working for a period of time, which is inconvenient to maintain. [0003] The working principle of the...
