Description
Technical field
The utility model relates to a kind of electric screw press device, especially relates to a kind of dc bus that is used for the fly press electrification feedback.
Background technology
China is suppressing, and forges to be in backwardness on the control technology always.Control power commonly used now is reluctance switch motor or asynchronous machine, and force de frappe can only be adjusted highly and realize, rise and fall are switched slowly during strike, inefficiency, and commutating speed is slow; When slowing down, there is not energy recycle device, the serious waste electric energy.Existing product drives with servo-driver, adds brake resistance with brake unit and realizes braking, and equipment is in frequent acceleration and deceleration work, and the energy that in moderating process, produces all is depleted on the resistance, produces very big waste; Brake unit generally is just to begin braking when voltage is higher than threshold value in addition, and electrical network can be elevated to the braking threshold when night sometimes, and brake resistance is partly damaged; Also possibly cause the servo-driver fault, cause system unstable.
Summary of the invention
The utility model purpose provides a kind of dc bus that is used for the fly press electrification feedback.Technical problems such as the existing cost of prior art is higher to solve, inconvenient debugging, the braking reliability is low, energy consumption is bigger.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the dc bus of fly press electrification feedback comprises three phase mains, filter rectification device, servo-driver, motor; Said three phase mains is connected with the filter rectification device, and this filter rectification device comprises three phase rectifier element, charge circuit, filtering storage capacitor; Said motor is connected with servo-driver.
As preferably, said three phase mains is connected with the three phase rectifier element, and this three phase rectifier element two is positive electrode bus and negative pole bus very, and said charge circuit is connected on the positive electrode bus, and the filtering storage capacitor is connected on positive electrode bus and the negative pole bus.
As preferably, said servo-driver is connected on positive electrode bus and the negative pole bus.
As preferably, said filter rectification device comprises three phase rectifier element, charge circuit; Said dc bus is connected with many servo-drivers, and every servo-driver connects a motor.
