It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Referring to fig. 1, in an embodiment of the present invention, a control method for automatic forging includes:
s1, setting a critical angle of a crankshaft corresponding to a punch press functional part;
s2, acquiring the angle of the current crankshaft;
s3, after the crankshaft is operated to a critical angle, acquiring the working state of the functional part of the die;
s4, if the die functional part completes or starts sub-actions in a preset sequence, the punch functional part continues to output, wherein the sub-actions are obtained by decomposing all action sequences of the punch functional part;
s5, if the die functional part does not complete or starts the sub-actions in the preset sequence, the punch functional part stops outputting, and waits for the die functional part to continue outputting after finishing all the actions.
In the present invention, in step S1, the critical angle corresponding to the crankshaft is set, and it is defined that the mold functional unit completes all the operations only when the angle of the crankshaft does not exceed the critical angle, and the continued operation of the crankshaft is high quality and safe. Firstly, in the automatic forging and cutting process, all actions of the functional part of the die are completed in the middle of a circle of 360-degree cycle of the crankshaft; then, the critical angle may be set between 90 degrees and 270 degrees in step S1. When the crank angle is 0 degree, the forging and cutting process is lifted; when the crank angle is 90 degrees, the crank is lifted to a half-height position of the top point; when the crank angle is 180 degrees, the crank is lifted to the vertex position; when the crank angle is 270 degrees, the crank angle is lowered by half the height position from the vertex; when the crank angle is 360 degrees, the forging process is about to be performed. The specific value of the critical angle can be selected according to the actual working state.
In step S2, the current crank angle is obtained, and the specific crank angle obtaining manner may be various, for example, mechanical, electromechanical or photoelectric sensing is adopted, so that the angle information is simply and accurately obtained.
In step S3, the working state of the mold functional part is obtained after the crankshaft is moved to the critical angle, and in this process, the output of the punch functional part is not stopped, that is, the crankshaft is not stopped, so that the working efficiency is improved, and the clutch consumption of the punch functional part is reduced.
In step S4, if the die functional unit completes or starts the sub-operations in the predetermined order, the forging press operation may be performed, and the punch functional unit may continue to output. In the process, the work of the punch functional part is not stopped all the time, so that the efficient, stable and low-consumption work is completed. The sub-actions obtained by sequentially decomposing all actions of the punch functional part can comprise a sub-action of a discharging function, a sub-action of a forging and cutting function, a sub-action of a material taking function and the like. The sub-actions of a typical preset order are the last order.
In step S5, if the die functional portion does not complete the sub-actions in the preset sequence, it is indicated that the forging operation is not possible, the punch functional portion stops outputting, and continues outputting after waiting for the die functional portion to complete all the actions, thereby ensuring the safety of the forging and cutting process. And (5) repeating the steps from S3 to S5, and completing the forging and cutting cycle. For example, there is a processor in which a critical angle can be set, and the processor also receives the angle information of the crankshaft and the operating state of the die function, and judges the state relationship between the crankshaft and the die function, thereby controlling the operation of the punch function. In general, when the crankshaft of the punch press functional unit completes half a cycle (reaches the top), the die functional unit completes one cycle of operation. However, both the punch press functional part and the die functional part can generate certain working time accuracy errors. In the invention, the crank shaft is not stopped by adopting a clutch in each cycle, and after a critical angle is set, the die functional part finishes the preset action before the critical angle, namely, the punch functional part can be judged to directly continue the work of the next cycle without stopping the work. In the above process, the work of the punch functional part can not be stopped due to the error of one matching process, so long as the critical condition can be met; after several cycles, the above-mentioned mating errors may naturally be counteracted.
In summary, the crankshaft is not stopped by a clutch in each cycle, and after a critical angle is set, the die functional part completes the preset action before the critical angle, that is, it is determined that the punch functional part can directly continue the next cycle without stopping. In the above process, the work of the punch functional part can not be stopped due to the error of one matching process, so long as the critical condition can be met; after several cycles, the above-mentioned mating errors may naturally be counteracted. Only when the die functional part does not complete the sub-actions of the preset sequence, the punch functional part stops outputting.
In one embodiment, the control method includes:
the start time of each sub-action of the die function is made to correspond to the angle of the crankshaft.
The work of the die functional part is controlled in a crank angle state of the punch functional part, rather than in a time manner, and the die functional part has the advantages of safety degree improvement and coordination degree improvement. It should be noted that the engagement between each sub-action is not limited to be completely seamless, and may have a certain interval, so as to avoid contradiction between the actions of the functional parts of the mold. The manner in which the start time of each sub-action corresponds to the angle of the crankshaft may be mechanical linkage or sensor linkage, specifically, the relation between the angle of the crankshaft and the functional part of the die is achieved. In this embodiment, the start time of each sub-action corresponds to the angle of the crankshaft, so that when the punch press functional portion stops outputting and the crankshaft is not rotated and waits for the next cycle, the operation of the die functional portion is not contradicted, which is advantageous for the cooperation between the punch press functional portion and the die functional portion. Although the start time of each sub-operation of the die functional portion is correlated to the angle of the crankshaft, a superior fit has been theoretically established. However, in the specific execution, since the punch press functional portion and the die functional portion are abnormal in operation, deviation is still formed, and at this time, the above abnormal operation can be adapted through the processes of steps S2 to S5. In the embodiment, the mutual coordination and the mutual locking between the punch functional part and the die functional part are realized, the coordination working process between the punch functional part and the die functional part is optimized, the working efficiency is improved, and the output stopping time of the punch functional part is reduced.
In one embodiment, the step of S4 includes:
if the last sequence of sub-actions of the die functional part is started, the punch functional part continues to output;
the step of S5 includes:
if the last sub-action of the die functional part is not started, the punch functional part stops outputting, and the die functional part continues outputting after finishing all actions.
In the present embodiment, first, the start time of each sub-action of the mold function portion corresponds to the angle of the crankshaft, and then the start timing of the sub-actions of the last order and the angle of the crankshaft form a strong correlation; then, if the output of the punch functional part is stopped, whether the sub-actions with the final sequence are started or not is judged, so that the maximum probability of complete all the actions of the die functional part can be ensured while the pre-judgment of one sub-action time can be advanced, and the efficiency and the reliability are compatible.
In one embodiment, the control method includes:
the start time of the sub-actions of the first order of the mold functional section is made to correspond to the angle of the crankshaft.
In this embodiment, only the start time of the sub-actions of the first order is corresponding to the angle of the crankshaft, and the rest of the sub-actions are completed sequentially in cooperation with the cooperation sub-actions of the first order. The complexity of the operation of the mold function corresponding to the crank angle is reduced.
In one embodiment, the step of S4 includes:
if the last sequence of sub-actions of the die functional part is finished, the punch functional part continues to output;
the step of S5 includes:
if the last sequence of sub-actions of the die functional part is not finished, the punch functional part stops outputting, and the die functional part continues outputting after finishing all actions.
In this embodiment, the preset actions in the step S4 and the step S5 are the last actions in the one-round circulation action of the functional part of the mold. The criterion for whether the punch press functional portion continues to output is whether the die functional portion completes all the operations, which is advantageous for safe operation between the entire punch press functional portion and the die functional portion.
In one embodiment, the step of S3 includes:
judging whether the sub-action of the penultimate sequence is finished or not after the crankshaft runs to a critical angle;
in the steps S4 and S5, the sub-actions in the predetermined order are sub-actions in the next to last order.
In this embodiment, the criterion for whether the punch press functional portion continues to output is whether the die functional portion completes the penultimate sub-action, which is advantageous for efficient operation between the entire punch press functional portion and the die functional portion. First, in practice, according to the concepts of the present embodiment, the criterion for decision making is not limited to sub-actions in the penultimate order; however, in the design concept of the punch press, the best working state should be that after the crankshaft reaches the top dead center, the working states of all the dies are in place, and at this time, the crankshaft continues to complete the action. Therefore, in the present embodiment, it is directly defined whether the sub-actions of the last but one order are completed, so that the pre-determination is made at the time point (or the crank angle point) when the die functional part completes all the work, and further, the punch functional part and the die functional part are more compact. The output stopping time of the punch functional part is more allowance, or the problem is less likely to occur; for example, if the judgment standard is that the mold functional part completes all the actions, the judgment result can be formed only at the moment when all the actions are completed, and if the judgment standard is that the next-to-last sub-actions are performed, the judgment of stopping output or continuing output of the punch functional part can be performed one sub-action in advance, so that the buffer time is provided, and the matching efficiency can be improved.
In one embodiment, in the step S1, the critical angle is selected in a range of 90 degrees to 270 degrees.
In the present embodiment, a more suitable critical angle range is given, and is not limited to the case of top dead center (180 degrees) in the prior art. Particularly, under the condition that the safety between the die functional part and the punch functional part is guaranteed, the critical angle can be set to be larger, and when small errors occur in the operation of some die functional parts at the moment, the output of the punch functional part cannot be suspended. Both the punch press functional part and the die functional part can generate a certain working time accuracy error. The crankshaft is not stopped by a clutch in each cycle, and before the critical angle, the die functional part completes the preset action, namely, the punch functional part can be judged to be capable of directly continuing the work of the next cycle without stopping the work. In the above process, the work of the punch functional part can not be stopped due to the error of one matching process, so long as the critical condition can be met; after several cycles, the above-mentioned mating errors may naturally be counteracted.
In one embodiment, the step of S2 includes:
the angle of the current crankshaft is obtained through a grating angle sensor arranged on the crankshaft.
In the present embodiment, by providing the grating angle sensors at the respective positions of the crankshaft, the angle information of the crankshaft can be accurately obtained. In other embodiments, other types of angle sensors may also be provided. The grating angle sensor is a measurement feedback device that works on the optical principle of a grating. For example, the grating ruler is a transmission type amplitude grating, and the principle is that when the main grating and the auxiliary grating are relatively displaced, the change of the moire fringes is generated, the change is converted into an electric signal by a precision photoelectric conversion device, and then the electric signal is processed by a signal processing circuit, and a digital signal with corresponding displacement is output. The grating ruler is often applied to a closed-loop servo system of a numerical control machine tool and can be used for detecting linear displacement or angular displacement. The signal output by the measuring device is digital pulse, and has the characteristics of large detection range, high detection precision and high response speed.
In one embodiment, a distance sensor is provided corresponding to a position on the die function corresponding to the punch function, the control method comprising:
receiving a distance signal sent by a distance sensor;
and if the distance signal is smaller than the preset distance threshold value, stopping the operation of the punch press functional part and sending a first alarm signal.
In this embodiment, a related sensing device is disposed on the functional part of the die, and the distance between the functional part of the die and the functional part of the punch is determined by the sensing device, and when the distance enters a dangerous range, it is indicated that the control method has a problem of setting and needs to be debugged. The distance sensor may be ultrasonic or contact, etc. For example, various sensors are disposed at relevant positions for the safety of the operation of the punching machine, and in this embodiment, relevant sensors are disposed at positions corresponding to the functional parts of the punching machine on the functional parts of the die, so as to reduce the possibility of collision between the two sensors.
In one embodiment, the control method includes:
after the crankshaft runs for a first preset number of cycles, counting the number of cycles of stopping output of the functional part of the punching machine as the waiting number;
and evaluating a control method according to the waiting times.
In this embodiment, a first preset number (for example, 1000 times) is preset, after the crankshaft runs by the first preset number, the number of cycles of stopping output by the functional part of the punching machine is counted, if the number of waiting times is excessive, it is indicated that there is a space for adjusting the setting of the control method, and if the number of waiting times is less, it is indicated that the setting of the control method is more suitable.

and the second judging and executing unit is used for stopping the output of the punch press functional part and waiting for the continuous output of the die functional part after the die functional part finishes all the actions if the die functional part does not finish or starts the sub-actions in the preset sequence.
