Abstract
The utility model relates to an energy-saving power device of a mechanical pressing machine, which comprises a main motor, a fly wheel and at least one auxiliary motor, wherein an output shaft of the main motor is connected with a main power output shaft through a coupler, the fly wheel is connected with the main power output shaft through belt transmission, and the auxiliary motor is connected with the main power output shaft through belt transmission; a rotary encoder is mounted on the main power output shaft; the main motor and the auxiliary motor are controlled by a programmable logic controller to be switched on and off; and output signals of the rotary encoder are connected into the programmable logic controller. Energy required by the working stroke of the mechanical pressing machine is mainly supplied by energy released by reducing the rotational speed of the fly wheel, the programmable logic controller utilizes changes in the rotational speed of the main power output shaft before and after the process of processing a workpiece to figure out the energy which is required by blanking and displaying the required motor power, and an operator can select the corresponding motor power according to detection data and switch off the redundant auxiliary motor selectively for achieving the purpose of saving energy.
Description
Technical field
The utility model relates to a kind of punching machine, particularly a kind of power set of punching machine.
Background technology
Punching machine is by slider-crank mechanism rotatablely moving of motor to be converted to the straight reciprocating motion of slide block, blank is formed the metal forming machinery of processing.Because its high efficiency, kinematic accuracy height, reliable operation is widely used in technologies such as punching press, extruding, die forging and powder metallurgy.Punching machine quantitatively accounts for the over half of all kinds of metal forming machinery sums.
The existing mechanical forcing press does not also have detection method to the energy that is consumed in the impulse stroke in moulding or stamping-out process, act on actual tonnage on the workpiece for slide block, can only realize detecting directly to make the tonnage instrument that is used for dynamic calibration firmly.The designer is when design, to determining and selected as calculated power of motor of press tonnage, all be to determine according to required moulding or the blanking pressure of workpiece that the user provides, added safety coefficient when selecting power of motor for use, add man-hour actual so, sometimes process required moulding of different workpieces or blanking pressure much smaller than design load, the power that is consumed is wasted a lot of electric energy much smaller than employed power of motor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of punching machine power set, can come the gross output of corresponding adjustment motor to realize energy-conservation according to the required blanking pressure of different workpieces.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of punching machine energy-saving power device, comprise main motor and flywheel, main motor output shaft is connected with the total output output shaft by shaft coupling, flywheel is connected with the total output output shaft by belt transmission, its innovative point is: also comprise at least one stand-by motor, described stand-by motor is connected with the total output output shaft by belt transmission; On the described total output output shaft rotary encoder is installed; Described main motor and stand-by motor open and close control by Programmable Logic Controller, and the output signal of rotary encoder inserts Programmable Logic Controller.
Advantage of the present utility model is: the energy that the punching machine impulse stroke is required, mainly reducing the energy that is discharged by the flywheel rotating speed supplies with, the required energy of machine and required motor power is shown when utilizing change calculations before and after the total output output shaft rotating speed in the processing work process to go out the stamping-out workpiece by Programmable Logic Controller, select corresponding power of motor by operating personnel according to detecting data, selectivity is closed unnecessary stand-by motor, thereby reaches purpose of energy saving.
Description of drawings
Fig. 1 is the utility model punching machine energy-saving power device embodiment front view.
Fig. 2 is the utility model punching machine energy-saving power device embodiment vertical view.
The specific embodiment
As shown in Figure 1, 2, comprise main motor 1, stand-by motor 2, stand-by motor 3, total output output shaft 4, flywheel 5.
Above-mentioned total output output shaft 4 is connected with flywheel 5 by belt transmission, the output shaft of main motor 1 is connected with total output output shaft 4 by shaft coupling, stand-by motor 2,3 is connected with total output output shaft 4 by corresponding belt transmission respectively, rotary encoder 6 is installed on total output output shaft 4, and the output signal of this rotary encoder 6 inserts Programmable Logic Controller.Main motor 1 and each stand-by motor open and close control by Programmable Logic Controller.
When the moulding of carrying out the different size workpiece or stamping-out, at first open all motors and carry out the driving of flywheel, utilize the change calculations of total output output shaft 4 rotating speeds front and back in the processing work process to go out this required gross energy of size workpiece slide block one stroke of stamping-out and required motor power is shown by Programmable Logic Controller, close unnecessary motor by operating personnel, thereby reach purpose of energy saving.
