Description

Technical Field

[0001] The utility model belongs to the technical field of seat belt mandrel processing, and in particular relates to a special monitoring system for a mandrel fine punching and cutting die. Background Art

[0002] like Figure 4 As shown, after the seat belt mandrel is formed, the four seat belt mandrels will connect the by-product connector and the by-product A. The function of the mandrel fine blanking and cutting die is to punch out the by-product connector and the by-product A. The punched-out by-product connector is pushed out by the pushing cylinder, and the punched-out by-product A falls out automatically. However, the mandrel fine blanking and cutting die may not be able to completely punch out the by-product connector and the by-product A. When this phenomenon occurs, the pushing cylinder still pushes the by-product connector, which will cause additional force to be applied to the by-product connector, the seat belt mandrel, and even the lower die core of the seat belt mandrel, or to related parts, which may cause damage or deformation of the seat belt mandrel of the part or even the lower die core of the seat belt mandrel. This phenomenon may also lead to a decrease in production efficiency because additional processing of incompletely punched parts is required, which increases the complexity and cost of the production process.

[0003] The entire operation process of the mandrel fine blanking and cutting die needs to be monitored to ensure that the by-product connector and by-product A are completely punched out. In view of this, we propose a special monitoring system for the mandrel fine blanking and cutting die. Utility Model Content

[0018] The dedicated monitoring system for the mandrel fine blanking and cutting die uses photoelectric sensors and proximity switches to detect the blanking of by-product A and by-product connectors.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The following is combined with Figure 1-6 To further explain this application in detail,

[0029] The embodiment of the present application discloses a dedicated monitoring system for a spindle fine blanking and cutting die, including a lower die base 1, a photoelectric sensor 6 and a proximity switch 7.

The seat belt spindles 2 on the four lower die cores 3 are connected by a by-product connector 4. Each of the seat belt spindles 2 is further provided with a by-product A5 at one end away from the by-product connector 4. The by-product connector 4 and the by-product A5 are punched out by a cutting die that cooperates with the lower die core 3.

[0030] The photoelectric sensors 6 are provided in four numbers and are used to detect the by-product A5 cut off by punching;

[0031] The proximity switches 7 are provided in three numbers and are used to detect the falling of the by-product connectors 4 cut off by punching;

[0032] The signal output ends of the photoelectric sensor 6 and the proximity switch 7 are connected to the signal input ends of the PLC controller 8. The PLC controller 8 receives input signals from the photoelectric sensor 6 and the proximity switch 7 and processes these signals.

[0033] The photoelectric sensor 6 adopts the Omron E3JK-DS30M1 photoelectric sensor 6, which is a commonly used photoelectric sensor suitable for detecting objects at a distance and has high stability and reliability.

[0034] The proximity switch 7 adopts the model of Sick IME12-04BNSZW2S, which is a commonly used proximity switch suitable for detecting metal and non-metal objects with high sensitivity and fast response speed.

[0035] The photoelectric sensor 6 and the proximity switch 7 are used to detect the blanking of the by-product A5 and the by-product connector 4 that have been cut off, ensuring that they are completely cut off, preventing the additional force caused by incomplete cutting from causing damage or deformation of the parts, and achieving complete cutting control of the by-product A5 and the by-product connector 4. The photoelectric sensor 6 and the proximity switch 7 transmit the detected signals to the PLC controller 8, so as to realize real-time monitoring of the cutting process of the lower mold core 3, and be able to handle abnormal situations in time to ensure the cutting quality and process stability, and realize real-time monitoring and feedback control. With the help of the monitoring system, additional process processing and product quality problems caused by incomplete cutting can be avoided, the production efficiency can be improved, the defective rate can be reduced, and the overall quality and consistency of the product can be guaranteed.

[0036] The lower die base 1 is provided with a blanking hole 9 for cooperating with the by-product A5 for blanking, and the lower die base 1 is provided with a mounting groove A10 connected to the blanking hole 9, and the photoelectric sensor 6 is installed in the mounting groove A10.

[0037] The drop hole 9 can ensure the smooth discharge of the by-product A5 and install the photoelectric sensor 6 in a position that is convenient for monitoring and maintenance, thereby improving the stability and reliability of the system.

[0038] Two mounting grooves B11 corresponding to the tail wings 41 on both sides of the by-product connector 4 are provided between the two lower mold cores 3 on the lower mold base 1. A mounting groove C12 vertically corresponding to the round block 42 on the by-product connector 4 is provided on the lower mold base 1. The three proximity switches 7 are respectively installed in the two mounting grooves B11 and one mounting groove C12. An opening groove 18 is provided on the lower mold base 1, and the mounting groove C12 is located below the opening groove 18.

[0039] The proximity switch 7 is installed in the installation groove B11 and the installation groove C12, which can accurately locate the tail 41 and the round block 42 of the by-product connector 4, ensuring that the proximity switch 7 accurately detects the position of the by-product connector 4 and improves the cutting accuracy and stability.

[0040] The lower die base 1 is provided with three mounting plates 13 at one end away from the mounting groove C12, and push cylinders 14 are respectively mounted on the three mounting plates 13, which are aligned with the tail wings 41 and the round block 42 on both sides, and the piston rod ends of the push cylinders 14 are provided with push plates 15. The push cylinders 14 are electrically connected to the PLC controller 8.

[0041] The photoelectric sensor 6 and the proximity switch 7 detect the by-product A5 and the by-product connecting part 4 that have been cut off. When the PLC controller 8 determines that the by-product A5 and the by-product connecting part 4 are completely cut off, the PLC controller 8 controls the action of the pushing cylinder 14 through precise control of the pushing cylinder 14, so that the pushing plate 15 aligns with and pushes the tail 41 and the round block 42 of the by-product connecting part 4, and pushes the by-product A5 and the by-product connecting part 4 off the material, ensuring that the cutting process is accurate and improving production efficiency and product quality.

[0042] The lower die base 1 is arranged on a bottom plate 16 , and an extension hole 17 connected with the blanking hole 9 is opened on the bottom plate 16 , so as to facilitate the blanking of the by-product A5 and the collection and discharge of the by-product A5 .

[0043] The special monitoring system of the mandrel fine blanking and cutting die, the photoelectric sensor 6 and the proximity switch 7 are connected to the PLC controller 8. These devices are used to detect the falling of the by-product A5 and the by-product connecting part 4. When the photoelectric sensor 6 detects that the by-product A5 falls, it will send a signal to the PLC controller 8. The PLC controller 8 will then determine whether the by-product A5 is punched out based on the signal. If not, the PLC controller 8 will trigger the cutting die to continue to move downward again to complete the cutting of the by-product A5. The proximity switch 7 sends a signal to the PLC controller 8 when the by-product connecting part 4 falls. The PLC controller 8 will then determine whether the by-product connecting part 4 is punched out based on the signal. If not, it will control the triggering of the cutting die to continue to move downward again to punch out the by-product connecting part 4. In this way, it can be ensured that the by-product connecting part 4 and the by-product A5 are completely punched out.
