Technical Field
[0001] The utility model relates to the technical field of bending machines, in particular to a safety interlocking protection device for multi-person debugging of a bending machine. Background Art
[0002] As is well known, a bending machine is a machine that can bend thin plates. After the machine is assembled, manual debugging is required. When multiple people debug the same device, the operators cannot fully see whether the surrounding environment is safe, and there are visual blind spots. This method has great uncertainty and insecurity.
[0003] Therefore, the utility model proposes a safety interlocking protection device for multi-person debugging of a bending machine. When debugging, the operator needs to press the interlocking device and step on the foot pedal switch, and the device can operate to achieve the purpose of ensuring the personal safety of the operator. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a safety interlocking protection device for multi-person debugging of a bending machine.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A safety interlocking protection device for multi-person debugging of a bending machine. A foot pedal switch is arranged on the movable foot pedal. The interlocking device includes a base, a pressing and rotating part, and a signal transmitter. A pressing channel is arranged at the center position of the base. The cross-section of the pressing channel is in an inverted "convex" shape structure. A positioning boss is arranged in the middle of the inverted "convex" shape structure. A semi-circular and semi-annular convex block one is fixedly arranged on the positioning boss. The signal transmitter is arranged at the bottom of the pressing channel;
[0007] It further includes an interlocking control system, and the interlocking control system is electrically connected to the interlocking device and the foot pedal switch.
[0008] Further, the pressing and rotating part includes a round head button, a pressing column, and a semi-annular convex block two. The bottom of the round head button is fixedly connected with the pressing column. The bottom of the pressing column is fixedly connected with the semi-annular convex block two. The pressing column is matched with the pressing channel and is slidably connected.
[0009] Further, a torsion spring is arranged inside the pressing channel. Two ends of the torsion spring are respectively connected to the bottom of the pressing channel and the bottom of the round head button.
[0010] Further, an annular space is formed between the upper part of the positioning boss and the outside of the torsion spring. The annular space is used for the up and down sliding of the semi-annular convex block two.
[0011] Furthermore, the pressing post, the second semi-circular protrusion, and the first semi-circular protrusion have equal thicknesses. Half of the arc length at the top of the first semi-circular protrusion and half of the arc length at the bottom of the second semi-circular protrusion overlap and contact each other. When the first semi-circular protrusion and the second semi-circular protrusion are pressed, they form a complete ring.
[0012] Furthermore, the linkage control system includes a main module for receiving signals one and two respectively from the foot switch and the linkage device, and a main module for processing signals one and two; the bending control system controls the operation of the bending machine.
[0013] Compared with existing technologies, this utility model provides a multi-person debugging safety linkage protection device for bending machines. Its advantages are:
[0014] 1. Portability: The linkage device is small in size and does not take up much space;
[0015] 2. High safety: The bending machine requires signals from both the linkage device and the foot switch before the operator can control its operation.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. At the same time, the terms "one", "two", etc. are only used to distinguish the names of each component and do not have a primary or secondary relationship, and therefore should not be construed as a limitation to the present utility model.
[0026] Example 1, as Figure 1 shown, a safety linkage protection device for multi-person debugging of a bending machine includes a bending machine main body, a movable foot pedal 1 and a linkage device 2. A foot switch 11 is provided on the movable foot pedal 1;
[0027] It further includes a linkage control system, and the linkage control system is electrically connected to the linkage device 2 and the foot switch 11.
[0028] Example 2, as Figures 1-4 shown, the linkage device 2 includes a base 3, a pressing and rotating member 4 and a signal transmitter. A pressing channel 31 is provided at the center position of the base 3. The cross-section of the pressing channel 31 is in an inverted "convex" structure. A positioning boss 32 is provided in the middle of the inverted "convex" structure. A semi-circular and semi-annular convex block one 33 is fixedly provided on the positioning boss 32. The signal transmitter is provided at the bottom of the pressing channel 31.
[0029] The pressing and rotating member 4 includes a round head button 41, a pressing column 42 and a semi-annular convex block two 43. The bottom of the round head button 41 is fixedly connected to the pressing column 42. The lower part of the pressing column 42 is fixedly connected to the semi-annular convex block two 43. The pressing column 42 is matched with the pressing channel 31, and the pressing column 42 can slide in the pressing channel 31.
[0030] A torsion spring 5 is provided inside the pressing channel 31. Both ends of the torsion spring 5 are respectively connected to the bottom of the pressing channel 31 and the bottom of the round head button 41. The torsion spring 5 is a spring that can bear torsional deformation and automatically reset.
[0031] The positioning boss 32 forms an annular space 6 above the torsion spring 5. This annular space 6 is used for the semi-circular protrusion 43 to slide up and down. When rotating the semi-circular protrusion 43, it can slide up and down and left and right within the annular space 6. Initially, the semi-circular protrusion 43 is completely inside the base 3.
[0032] The pressing post 42, the second semi-circular protrusion 43, and the first semi-circular protrusion 33 have equal thickness. Half of the arc length at the top of the first semi-circular protrusion 33 and half of the arc length at the bottom of the second semi-circular protrusion 43 are in overlapping contact. When the first semi-circular protrusion 33 and the second semi-circular protrusion 43 are pressed, they form a complete ring.
[0033] With this technical solution, the top half of the arc length of the semicircular protrusion 33 and the bottom half of the arc length of the semicircular protrusion 43 overlap and contact, thus the semicircular protrusion 33 holds the semicircular protrusion 43 in place. The pressing post 42 is also held in place by both the semicircular protrusion 33 and the semicircular protrusion 43, preventing the signal transmitter from being activated. When rotating the round-head button 41, only a 90-degree rotation is needed to press it down. Because the top half of the arc length of the semicircular protrusion 33 and the bottom half of the semicircular protrusion 43 overlap and contact, only a 90-degree rotation is required. Half the arc length of the second semicircular protrusion 43, the top of the semicircular protrusion 1 33 and the bottom 43 of the semicircular protrusion 2 will not overlap, so the semicircular protrusion 2 43 can slide down. When it slides to the positioning protrusion 32, it stops sliding. At this time, the two ends of the semicircular protrusion 2 43 and the two ends of the semicircular protrusion 1 33 are respectively joined together to form a complete ring. The pressing column 42 will also move into the pressing channel 31 to trigger the signal transmitter. Alternatively, a cylinder can be set inside the torsion spring 5 to connect the pressing column 42. When the round button 41 is pressed down, the cylinder can better trigger the signal transmitter.
[0034] The signal transmitter is existing technology and includes a signal modulation module and a signal processing module. When the signal modulation module receives the signal, it first modulates the information to be transmitted, converting the original signal into an electrical signal. The electrical signal is modulated and amplified and sent to the antenna. The antenna converts the electrical signal into an electromagnetic wave and finally transmits the electromagnetic wave. At this time, the signal receiving module receives the electromagnetic wave signal, converts the electromagnetic wave into an electrical signal, amplifies the electrical signal, and then the signal processing module decodes and processes the demodulated electrical signal to finally output a complete signal.
[0035] When the round head button 41 is released, the torsion spring 5 will automatically rotate and reset, and the pressing column 42 will rise to its initial position. The top half of the arc length of the semi-circular protrusion 33 will then abut against the bottom half of the arc length of the semi-circular protrusion 43, and the semi-circular protrusion 33 and the semi-circular protrusion 43 will be in vertical contact. Pressing the round head button 41 again will prevent it from moving downwards. This prevents accidental contact with the round head button 41 from triggering the signal transmitter.
[0036] In order to enable the linkage device 2 and the foot switch 11 to work together, a linkage control system is set up to control the signals of the linkage device 2 and the foot switch 11.
[0037] The linkage control system includes a main module for receiving signals one and two respectively from the foot switch 11 and the linkage device 2, and a main module for processing signals one and two. The bending control system controls the operation of the bending machine. When the bending control system receives a complete signal from the linkage control system, it will start the bending machine.
[0038] The linkage control system includes a command receiving module and a command processing module. The command receiving module includes a foot switch signal receiving module and a linkage device signal receiving module. The signal sent by the foot switch signal receiving module is signal one, and the signal sent by the linkage device signal receiving module is signal two. The command processing module processes signal one and signal two sent by the command receiving module. After processing the information of signal one and signal two, the command processing module transmits this information to the bending control system, and the bending machine starts to run.
[0039] The linkage system is integrated with the bending machine system on the bending machine's operation screen, making it convenient for operators to use.
[0040] The working principle of this utility model is as follows: Figure 5 and Figure 6 As shown, when debugging or using the bending machine, the linkage system enters the debugging mode after power-on. The operator first steps on the foot switch 11, which sends out signal one. At this time, the bending control system does not receive signals from both the foot switch 11 and the linkage device 2, and the equipment will not run. When another operator is notified and confirms that the environment around the bending machine is safe, rotate the round head button 41 ninety degrees. The two ends of the semi-circular protrusion 2 43 are in contact with the two ends of the semi-circular protrusion 1 33. Then press the round head button 41 down, and the pressing column 42 squeezes the torsion spring 5 down. The pressing column 42 triggers the signal transmitter and sends out signal two.
[0041] Once both signal one and signal two are received by the instruction receiving module, and then processed by the instruction processing module, the signals are transmitted to the bending control system. Upon receiving the signals, the bending control system will start the bending machine.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
