Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.

[0032] This application provides a safety protection system for punching equipment. This safety protection system is versatile and can be used in various pneumatic punch presses, cutting machines, and other punching equipment. The following description uses a punching equipment 100 including this safety protection system as an example.

[0033] Figure 1 and Figure 2 A front view and a side view of a punching device 100 provided in an embodiment of this application, such as... Figure 1 and Figure 2 As shown, the punching equipment 100 includes a machine base 10, a frame 20, a punching cylinder 30, a punching module, a safety protection system, and a control system.

[0034] A frame 20 is mounted on the upper surface of the machine base 10, and a punching cylinder 30 is mounted on top of the frame 20. The punching module includes an upper die 40 and a lower die 50. The upper die 40 is connected to the punching cylinder 30, and the lower die 50 is mounted on the upper surface of the machine base 10. A safety protection system is used for the overall safety protection of the punching equipment 100. A control system is used to control the operation of the punching cylinder 30 and the safety protection system.

[0035] The safety protection system includes a cylinder control protection module 60, a safety light curtain module 70, a fall protection module 80, and a start and emergency stop module 90.

[0036] The cylinder control and protection module 60 is used for the control and protection of the punching cylinder 30. For example... Figure 2 As shown, the cylinder control and protection module 60 includes an induction check valve 61 and a solenoid valve (not shown in the figure). The induction check valve 61 and the solenoid valve are connected sequentially between the air inlet of the punching cylinder 30 and the air path originally connected to the air inlet. The solenoid valve is used to control the opening and closing of the pilot port of the induction check valve 61 to achieve precise control of the working state of the induction check valve 61. Specifically, when the solenoid valve cuts off the air path to the pilot port, the pilot port is closed, and the gas to the punching cylinder 30 can only flow from the induction check valve 61 to the punching cylinder 30, and cannot flow in the reverse direction; when the solenoid valve opens the air path to the pilot port, the pilot port is open, and the gas to the punching cylinder 30 can flow bidirectionally between the induction check valve 61 and the punching cylinder 30.

[0037] The function of the cylinder control and protection module 60 is as follows: When the piston rod of the punching cylinder 30 moves, the pilot port of the induction check valve 61 is open under the control of the solenoid valve; when the piston rod of the punching cylinder 30 reaches the set position and needs to be locked, the pilot port of the induction check valve 61 is quickly closed under the control of the solenoid valve to prevent gas backflow, causing the piston rod to stop instantly and achieve precise positioning, while maintaining air pressure to prevent the piston rod from moving on its own after stopping. In this way, the cylinder control and protection module 60 ensures the stability and accuracy of the operation of the punching cylinder 30. When a sudden gas or power failure occurs on site, the solenoid valve will lose power and cut off the air path to the pilot port, causing the pilot port to close, and the punching cylinder 30 to stop instantly. The upper die 40 driven by the punching cylinder 30 will not fall rapidly, thereby reducing the occurrence of safety accidents.

[0038] As an example, the blanking cylinder 30 is a double-acting cylinder with two air inlets. The cylinder control and protection module 60 includes two induced check valves 61 and two solenoid valves. The two induced check valves 61 are respectively installed on the two air inlets of the blanking cylinder 30. A solenoid valve is installed between each induced check valve 61 and the air path originally connected to the air inlet. Each solenoid valve is used to control the opening and closing of the pilot port of the connected induced check valve 61. The solenoid valves can be center-leaking solenoid valves, which feature fast response, stable control, good compatibility, and low energy consumption.

[0039] The safety light curtain module 70 is used to detect whether a person or other object enters the processing area of ​​the blanking equipment, and sends a signal to the control system of the blanking equipment 100 when a person or other object is detected. Figure 1 As shown, the safety light curtain module 70 includes a transmitter 71 and a receiver 72. The transmitter emits an infrared beam, and the receiver 72 receives the infrared beam emitted by the transmitter. When an operator's hand or other object enters the area between the transmitter 71 and the receiver 72, causing the infrared beam to be blocked, the receiver 72 will immediately sense this change and send a signal to the control system. The control system will then control the punching cylinder 30 to stop working, thereby ensuring the safety of the operator and preventing accidents.

[0040] As an example, the safety light curtain module 70 includes a transmitter 71 and a receiver 72, which are respectively mounted on the left and right sides of the material loading / unloading port on the front side of the frame 20.

[0041] The fall protection module 80 is used to protect the punching cylinder 30 and the upper die 40 from falling. Specifically, when the upper die 40 falls due to power failure or insufficient air pressure of the punching cylinder 30, the fall protection module 80 can support the upper die base 41 of the upper die 40 to prevent the upper die 40 from falling. Figure 3 This is a schematic diagram of the structure of a fall protection module 80 provided in an embodiment of this application. Figure 4 An internal structural perspective view of a fall protection module 80 provided in an embodiment of this application is shown below. Figure 3 and Figure 4 As shown, the fall protection module 80 includes a base 81, an ejector plate 82, an ejector component 83, and a first drive component 84.

[0042] A base 81 is mounted on the machine tool 10 and located beside the lower mold 50. An ejector plate 82 is disposed on the side of the base 81 opposite to the lower mold 50. An ejector 83 is mounted on the ejector plate 82 and disposed within an ejection hole opened in the base 81, the ejection hole extending through the base 81 in the direction toward the lower mold 50. A first drive member 84 is mounted on the side of the base 81 opposite to the lower mold 50 and connected to the ejector plate 82. The first drive member 84 is used to drive the ejector plate 82 to move toward or away from the base 81, causing the ejector 83 to extend out of or retract from the ejection hole from the other side of the base 81.

[0043] The function of the anti-fall module 80 is as follows: when the punching cylinder 30 drives the upper die 40 to descend, the first driving component 84 drives the ejector plate 82 to move away from the base 81, and the ejector plate 82 drives the ejector component 83 to retract from the ejection hole from the other side of the base 81; when the punching cylinder 30 drives the upper die 40 to descend to the position, the first driving component 84 drives the ejector plate 82 to move towards the base 81, and the ejector plate 82 drives the ejector component 83 to extend out of the ejection hole from the other side of the base 81. In this way, when the upper die 40 falls due to power failure or insufficient air pressure of the punching cylinder 30, the ejector component 83 can support the upper die base 41 of the upper die 40, preventing the upper die 40 from falling and causing personal injury or property damage, thus playing a safety protection role.

[0044] As an example, there are multiple ejector pins 83 and ejector holes, all distributed along the height direction. This ensures that when the upper die 40 falls from different heights, there are ejector pins 83 of corresponding heights that can support the upper die base 41. The lower side of the end of the ejector pin 83 facing the lower die 50 is inclined. This ensures that when the punching cylinder 30 drives the upper die 40 to rise after punching, the ejector pin 83 contacts the upper die base 41 through the inclined surface without obstructing the upper die base 41 from moving upward. The first driving component 84 is a cylinder.

[0045] The fall arrestor module 80 also includes an elastic element 85, which is fitted onto the ejector 83 and abuts between the base 81 and the ejector plate 82. The elastic element 85 is used to provide a force to push the ejector plate 82 to move away from the base 81.

[0046] As an example, the elastic element 85 is a compression spring; the ejector 83 includes a supporting part 831 and a fixing part 832. The supporting part 831 is block-shaped and connected to one end of the fixing part 832. The fixing part 832 is rod-shaped and is installed on the ejector plate 82. The elastic element 85 is sleeved on the fixing part 832 and located between the supporting part 831 and the ejector plate 82.

[0047] The fall arrestor module 80 also includes a guide member 86, one end of which is connected to the base 81. The ejector plate 82 is fitted onto the guide member 86 and is movable along the guide member 86.

[0048] As an example, the guide member 86 is a guide rod and there are two of them. The two guide rods are parallel and are respectively set at the upper end and the lower end of the ejector plate 82. Each guide rod is fitted with a linear bearing 87 installed on the ejector plate 82. Through the cooperation of the guide rod and the linear bearing 87, the movement of the ejector plate 82 can be stable and smooth.

[0049] The start and emergency stop module 90 is used to control the start and stop of the punching equipment 100. The start and emergency stop module 90 includes a two-hand start button and an emergency stop button (both not shown in the figure).

[0050] The dual-hand start button requires both hands to be pressed simultaneously to start the punching machine 100, ensuring its safe start-up. Furthermore, if the control system uses PLC control, a delayed start program can be set; if it uses electrical control, a delayed start circuit can be set. This prevents operators from accidentally starting the equipment with one hand during material handling or other operations, fundamentally eliminating the safety hazards caused by single-handed operation, thereby reducing the occurrence of accidents and significantly improving the safety factor of equipment operation.

[0051] The emergency stop button, also known as the emergency stop button, will stop the operation of the punching equipment 100 when pressed. In case of an emergency, the operator can quickly press the emergency stop button to immediately stop the punching equipment 100, thereby preventing the further development of the accident.

[0052] The safety protection system also includes a workpiece fixing module. This module can be installed in either the upper die 40 or the lower die 50, for secondary fixing of workpiece 1. During the punching process, the workpiece fixing module ensures the stability and accuracy of workpiece 1, and also provides safety protection.

[0053] As an example, Figure 6 This is a front view of a punching module provided in an embodiment of this application. Figure 7 This is a schematic diagram of the structure of a lower mold 50 provided in an embodiment of this application, as shown below. Figure 6 and Figure 7 As shown, the punching module is a cutting die.

[0054] The upper die 40 includes an upper die base 41, a cutter fixing plate 42, a cutter 43, a stripper plate 44, stripper screws 45, and springs 46. The upper die base 41 is connected to the piston rod of the punching cylinder 30. The cutter fixing plate 42 is installed below the upper die base 41, and the cutter 43 is installed on the cutter fixing plate 42. The stripper plate 44 is located below the cutter fixing plate 42 and is connected to the upper die base 41 by multiple stripper screws 45. The stripper plate 44 has holes for the cutter 43 to pass through, and each stripper screw 45 is fitted with a spring 46 that abuts against the stripper plate 44 and the upper die base 41.

[0055] The lower mold 50 includes a lower mold base 51, a pad 52, a cutting base plate 53, a receiving box 54, and a workpiece fixing module. The lower mold base 51 is mounted on the machine base 10, the pad 52 is mounted on the lower mold base 51 and has a horizontally through-hole material box groove, the cutting base plate 53 is mounted on the pad 52 and is used to place the workpiece 1, and the receiving box 54 is installed in the material box groove and is used to collect the cut products.

[0056] The workpiece fixing module includes a pressure plate 55, a material root fixing plate 56, and a second driving component 57. The pressure plate 55 is rotatably mounted on the cutting base plate 53 and is used to press down on the workpiece 1 to prevent it from shifting during the cutting process. The material root fixing plate 56 is disposed on the cutting base plate 53. One end of the material root fixing plate 56 facing the pressure plate is used for secondary fixing of the workpiece 1, and the other end of the material root fixing plate 56 facing away from the pressure plate is connected to the second driving component 57. The second driving component 57 is mounted on a fixing block 58 connected to the side of the cutting base plate 53. The second driving component 57 is used to drive the material root fixing plate 56 to move towards or away from the pressure plate, causing the other end of the material root fixing plate 56 to press down on or release the workpiece 1. For example, the second driving component 57 is a cylinder.

[0057] The function of the workpiece fixing module is as follows: Initially, the pressure plate 55 is in the open state, and the second drive component 57 is in the retracted position. After the operator places the workpiece 1 to be processed onto the cutting base plate 53, the pressure plate 55 is flipped down to press down on the workpiece 1, preventing the workpiece 1 from shifting during the cutting process. When the control system receives the start signal, the second drive component 57, under the control of the control system, drives the material root fixing plate 56 to move towards the pressure plate and press down on the workpiece 1, performing secondary fixing on the workpiece 1, strengthening the fixing effect, and playing a safety protection role.

[0058] The control system can be, for example, a PLC control system. This PLC control system can also be connected to an external safety interlock protection circuit. When the PLC control system suddenly malfunctions or a certain point fails, the safety interlock protection circuit triggers a stop switch, causing the punching equipment 100 to stop operating immediately, thus also providing safety protection.

[0059] The working process of the blanking equipment 100: Initially, the blanking cylinder 30 is in the retracted state, the first drive member 84 of the anti-fall module 80 is in the extended state, and the second drive member 57 of the workpiece fixing module is in the retracted state. The operator places the workpiece 1 to be processed onto the cutting base plate 53 of the lower die 50, flips down the pressure plate 55 to press down the workpiece 1, and then presses the two-hand start button simultaneously to start the blanking equipment 100. After receiving the start signal, the control system controls the blanking cylinder 30 to drive the upper die 40 to descend, and at the same time controls the first drive member 84 to retract, so that the ejector 83 retracts into the ejection hole of the base 81, and at the same time controls the second drive member 57 to extend, so that the material root fixing plate 56 fixes the workpiece 1 a second time. When the punching cylinder 30 drives the upper die 40 to descend to its position, the punching cylinder 30 locks in place under the action of the cylinder control and protection module 60. Simultaneously, the control system controls the first driving component 84 to extend, causing the ejector component 83 to extend from the ejection hole of the base 81, providing fall protection for the punching cylinder 30 and the upper die 40. During the descent of the upper die 40, the cutter 43 cuts the workpiece 1 in the lower die 50, and the cut workpiece 1 falls into the receiving box 54. After cutting is completed, the control system controls the punching cylinder 30 to rise back to its initial position, awaiting the next start signal.

[0060] During the cutting process of the blanking equipment 100, the safety light curtain module 70 identifies and prevents people or other objects from entering the processing area. Once the receiver 72 senses that the infrared beam emitted by the transmitter 71 is blocked, the receiver 72 will send a signal to the control system, and the control system will control the blanking cylinder 30 to stop operating. In case of emergency, the operator can press the emergency stop button to quickly stop the operation of the blanking equipment 100.

[0061] In summary, the safety protection system and blanking equipment provided in this application embodiment, including the cylinder control protection module, safety light curtain module, fall protection module, and start and emergency stop module, provide comprehensive safety protection from aspects such as control of the blanking cylinder, entry detection of the processing area, fall protection of the blanking cylinder and upper die, and start and stop buttons of the equipment. This can significantly improve the safety protection effect and ensure the safety of operators and blanking equipment.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
