It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a distributed numerical control system for a bearing retainer, including a main controller, a sub-controller, and a numerical control production device.
And the main controller generates a control instruction according to the order information after acquiring the order information and transmits the control instruction to the plurality of sub-controllers.
The main controller can be a small computer or a high-grade microcomputer, and is provided with a corresponding display screen for human-computer interaction. Which may be associated with an enterprise resource planning system (Enterprise Resource Planning, ERP) to obtain corresponding order information, or may be manually entered. Corresponding control programs can be preset for bearing retainers with different demands in different order information, and control instructions corresponding to the control programs can be generated through identification retrieval.
The sub-controllers include a plurality of types including a general sub-controller, a shunt sub-controller, and a parallel sub-controller. Corresponding control programs can be pre-built among different types of sub-controllers, and can be adapted to the functions of the sub-controllers, for example, serial and parallel control programs are pre-arranged in the universal sub-controller and the parallel sub-controller respectively, and a control program of a judging module is pre-arranged in the shunt sub-controller.
The universal sub-controller is used for controlling one or more first numerical control production devices with production sequences, for example, in the production and processing process of the bearing retainer, the processing processes of moving, coiling, leveling, stamping and separating and the like are needed to be sequentially performed through a travelling crane, a coiling machine, a leveling machine and a stamping machine, and the universal sub-controller has strict sequence, so that the universal sub-controller is used as the first numerical control production devices and is used for controlling the first numerical control production devices.
The parallel sub-controller is used for controlling a plurality of second numerical control production devices capable of working simultaneously. The second numerical control production equipment can be a plurality of identical equipment, for example, a plurality of punching machines, so that the processing efficiency in the punching process can be improved. Of course, it can also be a plurality of different but simultaneously operable numerical control production devices, for example, still a plurality of punches, but with different punching dies used for producing and processing different types of bearing holders.
The splitter controller is used for controlling third numerical control production equipment, the third numerical control production equipment is arranged in front of the second numerical control production equipment, a plurality of branches are connected behind the third numerical control production equipment, and each branch is provided with the second numerical control production equipment.
The branch controller is connected with a plurality of branches, and second numerical control production equipment capable of working simultaneously is arranged on the branch, and the processing state of the subsequent branches can be controlled through the branch controller, so that the two branches can be in an efficient working state, and the processing efficiency is improved. The third numerical control production equipment can be a deflection feeder, and the middle piece obtained by punching and separating is sent to different branches through the control of the magnitude and the direction of wind power.
The sub-controller is used for controlling the production of the numerical control production equipment controlled by the sub-controller according to the control instruction, monitoring the working state of the numerical control production equipment and feeding back the working state to the main controller, so that the main controller can conveniently adjust in real time according to the working state.
And the numerical control production equipment executes corresponding production actions according to the control of the sub-controllers.
The multi-level structure is designed in the distributed numerical control system, each sub-controller is classified, once newly added equipment is integrated into a production line, the newly added equipment can be classified under the corresponding sub-controller, or the sub-controllers of the same type are newly added according to the existing sub-controllers, and each hardware interface and software protocol are not required to be changed, so that the flexibility of the control system can be improved.
For the equipment with lower processing efficiency, once the equipment meets the requirements of the second numerical control production equipment, other corresponding second numerical control production equipment is added for the equipment, and the processing efficiency of the equipment is improved, and meanwhile, the processing efficiency of other residual equipment is also improved, so that the utilization rate of the equipment is improved.
In one embodiment, the processing technology of the punching machine is generally simpler, the processing efficiency is higher compared with that of a punching machine, a stretching and bottom cutting machine and the like at the rear of the punching machine, and the punching machine and the stretching and bottom cutting machine are difficult to match with high-efficiency operation of the punching machine, so that the punching machine can generate longer working window period easily.
Based on this, the first numerical control production equipment comprises a punching machine, the third numerical control production equipment comprises a deflection feeder, and the second numerical control production equipment comprises the same numerical control production equipment group, for example, a punching machine, a stretching and bottom cutting machine and the like can be included, and of course, a plastic coating machine and the like can also be included.
And the main controller is used for determining the first machining efficiency of the punching machine (for example, the machining efficiency can be determined by the machining completion number in each minute) according to the working state fed back by the sub-controllers, determining the sub-machining efficiency of each device in each numerical control production device group and taking the lowest sub-machining efficiency as the second machining efficiency of each second numerical control production device. For a numerically controlled production equipment group, the processing efficiency is often determined by the equipment with the lowest sub-processing efficiency.
And controlling the feeding direction of the deflection feeder according to the second processing efficiency, wherein different feeding directions correspond to different branches. For example, the second processing efficiency is collected in real time, the branches with higher second processing efficiency are more middleware distributed by the deflection feeder, and therefore equipment on each branch is utilized to the greatest extent.
When the first machining efficiency is higher than the sum of all the second machining efficiencies, the machining efficiency of the punching machine is too high, if the machining is performed according to the current machining efficiency, excessive middleware is easily accumulated, the working window period of the punching machine is increased, and when the equipment, particularly large-scale equipment, is used for machining the same number of products, the power consumption of the stable operation process is lower than that of the repeated start-stop operation, so that the first machining efficiency is reduced, and the power consumption is saved.
In one embodiment, when multiple types of bearing retainers need to be machined in order information, conventional control schemes typically require multiple production lines to machine, or only one production line is used to machine one type of bearing retainer, and then another type of bearing retainer is machined by manual replacement procedures, equipment fittings, and the like.
Based on the above, the first numerical control production equipment comprises a punching machine, the third numerical control production equipment comprises a deflection feeder, the second numerical control production equipment comprises different numerical control production equipment groups, the first numerical control production equipment groups at least comprise a first punching machine and a stretching bottom cutting machine, and the second numerical control production equipment groups at least comprise a second punching machine and a nailing machine. Similar to the above embodiments, other devices such as a plastic coating machine may be included in the first and second numerically controlled production device groups.
And the main controller is used for determining that the acquired order information comprises a plurality of types of bearing retainers, wherein the types at least comprise conical bearing retainers and deep groove ball bearing retainers. The conical bearing holder is punched by a punch to obtain a conical intermediate member, and then subjected to processes such as punching (punching on the side face) and undercut. In the deep groove ball bearing retainer, it is necessary to punch the annular intermediate member by a punch, and to perform processes such as punching (punching on the annular surface) and nailing.
At this time, the main controller generates a punching rule according to the order information, generates a corresponding punching separation control instruction, and sends the punching separation control instruction to the first numerical control production equipment corresponding to the punching machine. Of course, the control instructions for the second numerical control production device are also sent synchronously, and will not be described in detail here.
Wherein, the punching rule includes: punch working frequency, punch working time and blank window time length, raw material plate feeding direction and raw material plate feeding distance. The ram operating frequency means the frequency at which the ram is operated, for example, the ram operating frequency is 1 time/s. The punch working and window time length indicates the working time length of each working and pause of the punch, for example, the punch is stopped for 30s after each working for 1 minute, and then the punch enters the working state. The raw material plate feeding direction and the raw material plate feeding distance represent how to control the feeding of the raw material plate.
And controlling the deflection feeder to convey the intermediate piece to the corresponding numerical control production equipment group according to the punch working frequency, the punch working and the window blank time length in the punching rule. For example, when the punch corresponding to the conical bearing retainer works, the deflection feeder conveys the punch to the first numerical control production equipment group when the punch is lifted.
And the first numerical control production equipment corresponding to the punching machine controls the punching machine through a punching separation instruction, and performs punching separation on the raw material plate according to a punching rule.
Further, in actual operation, two production forms are often included, that is, a plurality of punching machines are respectively provided, each punching machine corresponds to a different punch, or a punching machine provided with a plurality of punches, at this time, respectively corresponds to different control schemes.
As shown in fig. 2a, in case of a plurality of punches, the punches include a first punch connected to a previous apparatus, a second punch connected to the first punch, the first punch and the second punch being used for producing one of a conical bearing holder, a deep groove ball bearing holder, respectively, the first punch and the second punch producing different bearing holders, which bearing holder is produced, respectively, is not limited here. The deflection feeder comprises a first deflection feeder matched with the first punching machine and a second deflection feeder matched with the second punching machine, and subsequent equipment of corresponding branches is respectively connected with the first deflection feeder and the second deflection feeder, so that two branches are formed.
And the main controller generates a stamping rule according to the order information. At this time, in the punching rules corresponding to the first punching machine and the second punching machine, the feeding direction of the raw material plate and the feeding distance of the raw material plate are the same, and no change is made. The two are different in punch working frequency, punch working and window blank time length, and can be set according to actual working requirements.
As shown in fig. 2b, the press is a multi-punch press, which is used for producing one of the conical bearing holder, the deep groove ball bearing holder, respectively, and similarly as above, also the corresponding preceding apparatus and the following apparatus of the following respective branch are connected.
And the main controller generates a stamping rule according to the order information. At this time, since there is only one press machine, the raw material plate feeding direction and the raw material plate feeding distance are not changed. And determining the working time of the punch according to the punch working and the window blank time in the punching rule, and controlling the deflection feeder to convey the intermediate piece to the first numerical control production equipment group when the punch corresponding to the conical bearing retainer is lifted according to the punch working frequency when the punch is working, and controlling the deflection feeder to convey the intermediate piece to the second numerical control production equipment group when the punch corresponding to the deep groove spherical bearing retainer is lifted.
Furthermore, in the case of a multi-punch punching machine, since different types of intermediate members are punched and separated from one another on the same raw material plate, it is necessary to set the punching rule in advance.
Based on this, the main controller determines the intermediate pieces corresponding to the conical bearing holder and the deep groove ball bearing holder, respectively, based on the order information, and the size of the press-separated area required when press-separating is performed, typically, there is a certain interval between each intermediate piece, so the size of the press-separated area is larger than that of the intermediate piece, and the larger program can be set based on the actual situation (for example, determined according to the material of the raw material plate), and determines the width information of the raw material plate.
According to the width information, the sizes of the stamping separation areas respectively corresponding to the conical bearing retainer and the deep groove ball bearing retainer are combined so that the maximum number of stamping separation areas exist on the same width at the same time. As shown in fig. 3, a combination is shown in which one conical bearing holder and one deep groove ball bearing holder are combined with corresponding press separation areas, respectively, wherein area 1 is the press separation area corresponding to the conical bearing holder and area 2 is the press separation area corresponding to the deep groove ball bearing holder.
And determining the first area utilization rate of the combination for the raw material plate according to the size of the combined area obtained by the combination. For a raw material plate of the same length (generally, the length is far greater than the width), the lower the area of the residual raw material is after stamping separation on the raw material plate, the higher the area utilization ratio is, and the less waste of the raw material is. According to the conical bearing retainer and the deep groove ball bearing retainer, the area utilization rates of the raw material plates are averaged separately, and the second area utilization rate is obtained. That is, when only a single bearing holder is used, the corresponding area utilization ratio is obtained.
If the first area utilization rate is higher than the second area utilization rate, the manner of describing the combination saves more raw materials, and at this time, the corresponding punching rule is generated by the manner of the combination. If the first area utilization rate is lower than the second area utilization rate, each punch is made to work independently, and when the punch works, a stamping rule matched with the punch is set, in the stamping rule, when one punch works, the other punch does not work, so that the corresponding stamping rule needs to be set independently.
In one embodiment, when a production device is newly added, the main controller determines the newly added production device, determines whether other production devices of the same type as the newly added production device exist, and if so, can directly use the newly added production device as a second production device to control the newly added production device through a corresponding parallel sub-controller. Of course, in some scenarios, it is also necessary to determine whether the corresponding processing technologies of the two are the same, and only when the two are the same, the second numerical control production device can be determined.
Alternatively, it is determined whether there is another numerical control production apparatus having a specified production process which is after the same production process as that of the newly added numerical control production apparatus and is used for producing a different type of bearing holder, such as mentioned above, corresponding to different processing processes respectively when corresponding to the conical bearing holder and the deep groove ball bearing holder after the corresponding press separation process of the press machine: a side punching process, a stretching and bottom cutting process, an annular surface punching process and a nailing process. In this case, both of the bearing holders correspond to different types of bearing holders, and thus can be controlled by the corresponding parallel sub-controllers as the second numerical control production equipment.
Of course, if the newly added production equipment does not belong to the second production equipment, it can be clarified whether the newly added production equipment belongs to the third production equipment, if so, the corresponding split sub-controller is newly added for control, and if not, the existing general sub-controller can be newly added or used for control.
In one embodiment, upon deleting a production device, the master controller determines to delete the numerically controlled production device and determines that the deleted numerically controlled production device belongs to the second numerically controlled production device. At this time, in the distributed numerical control system, the control program corresponding to the deleted numerical control production equipment is not deleted directly, but in the parallel sub-controller corresponding to the deleted numerical control production equipment, a temporary virtual numerical control production equipment is generated to replace the deleted numerical control production equipment, and the preset time period is continued. The temporary virtual numerical control production equipment does not exist in entity equipment, and a control program corresponding to deleting the numerical control production equipment is basically unchanged. During its persistence, the master controller may be assigned a workload of 0 when it is assigned a job. At this time, if the numerical control production equipment is deleted, the new equipment is replaced, and the gap between the new equipment and the old equipment is not too large because the new equipment is replaced, and the new equipment can be directly replaced with the virtual equipment in the control program at this time, and the new equipment does not need to be reprogrammed and only needs to be finely tuned.
After a preset time period (such as one week) is reached, or when related instructions are manually and actively provided, if other numerical control production equipment is not added in the parallel sub-controllers corresponding to the numerical control production equipment, and a plurality of second numerical control production equipment capable of working simultaneously does not exist, the adjustment is not for replacing equipment, but for deleting equipment, at the moment, virtual numerical control production equipment does not exist, and the parallel sub-controllers corresponding to the numerical control production equipment are deleted, and the parallel sub-controllers are changed into universal sub-controllers or shunt sub-controllers according to a production process.
