Description
Technical Field
The invention relates to the field of high-speed presses, in particular to a restarting method and restarting system of a high-speed press and the high-speed press.
Background
With the development of technology, in recent years, the high-speed press lines at home and abroad are equipped with a one-key recovery function. When the small loose high-speed press line is in normal production, a clutch brake is adopted for normal production operation, and when general faults occur and equipment needs to be recovered, a one-key recovery function is often adopted to recover the equipment to an initial state so as to restart the equipment.
As shown in fig. 1, the high-speed press comprises a clutch brake mechanism 10, a gear train mechanism 20, a brake disc 30, a brake motor 31, a brake speed reducer 32, a flywheel 41 and a flywheel main motor (not shown in the figure) for driving the flywheel 41 to rotate; wherein, the gear train mechanism 20 is in transmission connection with the clutch brake mechanism 10. In particular, the train wheel mechanism 20 is also drivingly connected to a press ram 50 (not shown).
In normal operation of the high-speed press, the brake motor 31 in driving connection with the brake disc 30 does not operate. When the clutch brake mechanism 10 and the clutch disc 40 are combined and connected together, the gear train mechanism 20 is in transmission connection with the flywheel 41, and the subsequent gear train mechanism 20 is driven by the flywheel 41 to perform stamping motion of the press. When the clutch brake mechanism 10 and the brake disc 30 are integrally connected together, the subsequent train mechanism 20 is in a braking state.
In the event of a malfunction, in which the press ram 50 is stopped at a certain angle, the clutch brake mechanism 10 and the brake disc 30 are coupled together. And, normally, the high-speed press is in an automatic state, and only the press slide 50 can normally start the operation of the high-speed press at the top dead center position. If the press ram 50 is not at the top dead center position, the high speed press cannot be started even if a start signal is input to the control system, and this is provided to avoid the repeated start of the high speed press, etc., because of safety requirements. In this case, when the high-speed press is restarted, the clutch brake mechanism 10 is not separated from the brake disc 30, and the brake disc 30 drives the clutch brake mechanism 10 to rotate together under the driving of the brake motor 31 and the brake speed reducer 32, so that the following gear train mechanism 20 and the press slide 50 are driven to move, and the normal starting position is restored, and then the automatic starting is performed.
However, the restarting process is highly dependent on the working condition of a motor braking system, namely, the pressing machine sliding block is driven to rotate by the braking motor, and if the pressing machine is abnormal, the high-speed pressing machine cannot be restarted by one key, so that the production efficiency of the high-speed pressing machine is affected.

Detailed Description
Further advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present invention, which is described by the following specific examples.
It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the invention to the extent that it can be practiced, since modifications, changes in the proportions, or otherwise, used in the practice of the invention, are not intended to be critical to the essential characteristics of the invention, but are intended to fall within the spirit and scope of the invention. Also, the terms such as "upper", "lower", "left", "right", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the invention for which the invention may be practiced or for which the relative relationships may be altered or modified without materially altering the technical context.
As shown in fig. 1, 2 and 3, an embodiment of a high-speed press restarting method includes a first restarting method, the first restarting method including: the driving clutch brake mechanism 10 is connected with the clutch disc 40; acquiring the current position of the press slide 50; judging whether the position angle of the press slide block is larger than a preset angle; if the position angle of the press slide block 50 is larger than the preset angle, maintaining the direction and the rotating speed of the flywheel main motor unchanged, and inputting a high-speed press starting signal to start the high-speed press when the flywheel main motor drives the press slide block 50 to move to the upper dead point position; if the angle of the press slide 50 is smaller than the predetermined angle, the flywheel main motor is stopped first to drive the flywheel main motor to rotate reversely, and when the flywheel main motor drives the press slide 50 to move to the top dead center position, the flywheel main motor is stopped first and then driven to rotate forwardly, and a high-speed press starting signal is input to start the high-speed press.
The reverse rotation of the flywheel main motor means that the flywheel main motor drives the flywheel to rotate reversely when the output shaft of the flywheel main motor rotates in the direction opposite to the rotation direction of the flywheel when the high-speed press performs normal punching operation. The forward rotation of the flywheel main motor refers to the rotation direction of the output shaft of the flywheel main motor and the rotation direction of the flywheel driven by the flywheel main motor when the high-speed press performs normal punching operation.
As shown in fig. 2, the high-speed press slide 50 slides up and down in a predetermined track under the driving of the rotation of the flywheel 41, and each actual position of the press slide 50 may approximately correspond to a position angle. Fig. 2 shows the correspondence between the actual position and the position angle of the high-speed press slide 50. Assuming that the press ram 50 returns to the highest position after moving from the highest position to the lowest position for one cycle, it is possible to draw a graph in which the vertical axis is the actual ram position and the horizontal axis is the position angle, and a graph is obtained that extends from left to right along the horizontal axis. As shown in fig. 2, the data of the press ram 50 during operation can be made into a virtual circular motion according to the actual position of the press ram 50 and the angle of the press ram 50 for easy understanding.
The bottom dead center position B of the press ram 50 is approximately at the lowest point of operation of the press ram 50, which is at an angle of 180 °. When the high-speed press slide 50 operates normally, the press slide 50 is driven by the flywheel 41 to move from the highest point to the lowest point, and the angular rotation direction is rotated from 0 ° to 180 ° to reach the bottom dead center of the press slide 50. Next, the press ram 50 is moved from the lowest point toward the highest point, and the angular rotation direction of the position is turned from approximately 180 ° to 360 ° (0 °), during which movement the press ram passes through the top dead center position a of the high-speed press. As shown in fig. 2, the press ram 50 has an actual top dead center position a, a top dead center position A1 in the coordinate curve, and a top dead center position A2 in the drawn circular motion map; the press ram 50 has a bottom dead center position B1 in the coordinate curve and a bottom dead center position B2 in the drawn circular motion map. When the high-speed press fails and a restart is required, the position angle of the press ram 50 is in the range of 0 ° to 359 °, but the specific position cannot be determined. The predetermined angle in the present invention is 180 °. The restarting method of the high-speed press utilizes the flywheel 41 and the flywheel main motor to bring the press sliding block 50 to the upper dead point position, and realizes the restarting of the high-speed press after inputting a high-speed press starting signal.
When the position angle of the press slide block 50 is larger than a preset angle, the rotation direction and the rotation speed of the flywheel main motor are unchanged after the high-speed press is started; when the position angle of the press slide block 50 is smaller than the preset angle, the flywheel main motor is stopped and reversely rotated to the preset speed and then drives the flywheel main motor to reversely rotate, and when the flywheel main motor drives the press slide block to move to the upper dead point position, the flywheel main motor is stopped and then drives the flywheel main motor to positively rotate, and the starting signal of the high-speed press is output, so that the starting of the high-speed press can be realized.
Further, the embodiment may select the first restart method or the second restart method; if the first restarting method is selected, starting the high-speed press by adopting the first restarting method; if the second restarting method is selected, the brake motor 31 is started, and when the brake motor 31 drives the press slide 50 to move to the upper dead point position A, a high-speed press starting signal is input, and the high-speed press is started.
It should be noted that, when the high-pressure machine is in normal operation and is not in a braking condition, the clutch brake mechanism 10 is connected with the clutch disc 40; when a failure occurs, the clutch brake mechanism 10 automatically applies a brake to the brake disc 30. When the first restarting method is adopted, the clutch brake mechanism 10 is automatically attached to the clutch disc 40 when the flywheel main motor is started and drives the clutch disc 40 to rotate.
The second restarting method brings the press slide 50 to a predetermined position (i.e., the top dead center position a) by the brake motor 31, thereby realizing restarting of the high-speed press; by means of the brake motor 31 and the flywheel main motor, the press sliding block 50 moves to a preset position, any method can be independently selected by the high-speed press restarting method, and the phenomenon that the high-speed press cannot be restarted when a related system of the brake motor 31 fails is avoided.
Accordingly, as shown in fig. 1-4, an embodiment of a high speed press restart system 100 includes a first restart module 130, the first restart module 130 including: an acquisition unit 131 for acquiring a current position angle of the press ram 50; a judging unit 132 that judges whether or not the position angle at which the press slider 50 is positioned is greater than a predetermined angle; the control unit 133 is used for controlling the start and stop, steering and rotating speed of the flywheel main motor and outputting a high-speed press start signal; if the position angle of the press slide block 50 is greater than the preset angle, the direction and the rotating speed of the flywheel main motor are unchanged, and when the flywheel main motor drives the press slide block 50 to move to the upper dead point position A, the control unit 133 outputs a high-speed press starting signal to start the high-speed press; if the angle of the press slide 50 is smaller than the predetermined angle, the flywheel main motor is turned off and is reversed to a predetermined speed, and when the flywheel main motor drives the press slide 50 to move to the top dead center position, the control unit 133 outputs a flywheel main motor shutdown signal, a flywheel main motor forward rotation signal and a high-speed press start signal, so that the flywheel main motor is stopped first and then rotates forward, and then the high-speed press is started.
The high-speed press restarting system 100 of the present embodiment is an improvement of the original high-speed press control system, in which the high-speed press starting signal is output from the control unit 133 to the original control system of the high-speed press, and the high-speed press starting signal is received in the original control system when the press slide 50 passes through the top dead center position as mentioned in the background art, so as to restart the high-speed press.
Specifically, the acquiring unit 131 may be a first position sensor, directly acquire the current position information of the press ram 50, and the position information of the current ram (i.e., the current position angle) is directly input to the judging unit 132 to be compared with the predetermined angle. The control unit 133 is configured to control an operation state of the flywheel main motor by outputting a start-stop signal, a steering signal, and a rotation speed signal of the flywheel main motor based on the comparison result. Of course, a second position sensor may be provided at the top dead center position for capturing whether the press ram 50 is about to pass the top dead center position; or judging whether the press ram 50 is about to pass the top dead center position according to the comparison result of the top dead center position angle and the position angle of the press ram 50, the control unit 133 outputs a high-speed press start signal based on the information, thereby realizing the start of the high-speed press. The high-speed press restarting system 100 controls the running state of the main flywheel main motor to bring the press slide 50 to a preset position based on the comparison result of the position angle of the high-speed press slide 50, thereby realizing the restarting of the high-speed press and saving the cost.
Preferably, the high-speed press restarting system 100 further comprises a selecting module 110 and a second restarting module 120, wherein the selecting module 110 is configured to select the first restarting module 130 or the second restarting module 120 for restarting the high-speed press; the second restarting module 120 is configured to start the brake motor 31 and output a high-speed press start signal, where the brake motor 31 drives the press slide 50 to move to the top dead center position, and the second restarting module 120 outputs the high-speed press start signal to start the high-speed press. This avoids the situation that the high-speed press cannot be restarted when the related system of the brake motor 31 fails. Specifically, the selection module 110 may be a switch, and when the switch is turned on and the device needs to be restarted, the first restart module 130 is used to restart the high-speed press; when the change-over switch is turned off, and when the device needs to be restarted, the high-speed press is restarted by adopting the first restarting module 130.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
