Description

Technical Field

[0001] The utility model relates to the technical field of machine tool safety, in particular to a forging machine tool protection device. Background Art

[0002] Forging machines are equipment used for cold processing of metals and machinery. They only change the external shape of metals. Forging machines include plate rolling machines, shearing machines, punching machines, presses, hydraulic presses, oil presses, bending machines, etc. These machines are widely used in the metal processing industry and can change the shape of metals by forging to obtain the required parts or products. The working principle of forging machines is mainly to cause plastic deformation of metals by pressure to obtain the required shape and size. Different types of forging machines may differ in structure and working principle, but their core function is to process metal billets into workpieces with specific shapes and sizes. The protective device of forging machines, especially the photoelectric safety protection device, is an important safety device in machine tool operation. Its main function is to set up a protection area between the machine operator and the dangerous working area. Once a part of the operator enters this protection area and blocks the light curtain, the control system will immediately output a signal to the safety actuator of the forging machine to make the machine stop urgently, thereby preventing the occurrence of dangerous actions.

[0003] Most of the existing protective devices for forging machines are photoelectric protectors. The infrared warning line in the photoelectric protector is usually invisible to the operator's visual image. This is because infrared light is outside the visible spectrum of the human eye, so the operator cannot directly see the infrared warning line. However, although the infrared warning line itself is invisible, the photoelectric protector is usually equipped with some visual indicating devices, such as light-emitting diode indicator lights or visual infrared transmitters, to display the working status of the protector. However, the current visual infrared transmitters are mostly in the normally open state when used as warning lines. During the long-term work of the operator, this type of warning light can easily cause visual fatigue to the operator's eyes, affect the operator's working state, and increase the possibility of force danger. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a forging machine tool protection device to solve the technical problem that the warning light can easily cause visual fatigue to the operator's eyes and affect the operator's working state.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a forging machine tool protection device, comprising an operating table and a hydraulic device body, a trigger mechanism is arranged on one side of the hydraulic device body, a safety component is arranged on the front surface of the operating table, the safety component comprises a mounting plate, a first photoelectric sensor and a second photoelectric sensor are arranged on the top of the mounting plate, and an infrared emitter is arranged on one side of the first photoelectric sensor.

[0006] By adopting the above technical solution, through the intelligent control mechanism, the infrared transmitter is only activated when necessary, that is, when the operator's hand enters the sensing range of the second photoelectric sensor, once the hand moves out of the sensing range, the infrared transmitter will stop working immediately. This design effectively avoids the infrared transmitter from working for a long time, thereby reducing the risk of visual fatigue to the operator's eyes. The reduction of visual fatigue not only helps to improve the comfort of the operator, but also maintains their work efficiency and concentration, thereby indirectly improving the safety of the workplace.

[0007] Furthermore, the safety components are provided in two groups, and the two groups of the safety components are arranged in a mirror image along the length line of the operating table.

[0008] By adopting the above technical solution, comprehensive coverage of the operating area of ​​the operating table can be achieved. This layout ensures that during the entire working process of the forging machine, no matter which side of the operating table the operator's hand appears, it can be detected in time by at least one set of safety components, thereby effectively improving the equipment's safety protection capabilities for operators and reducing the risk of accidental injuries.

[0009] Furthermore, a plurality of infrared emitters are provided, and the plurality of infrared emitters are linearly arranged along a height line of the first photoelectric sensor.

[0010] By adopting the above technical solution, a more accurate and comprehensive safety warning effect can be achieved. This arrangement enables the infrared transmitter to cover a wider area. No matter what position the operator's hands are in, they may be illuminated by the infrared warning line emitted by at least one infrared transmitter, thereby effectively reminding the operator to pay attention to safety and prevent their hands from entering dangerous areas, thereby improving the equipment's safety protection capabilities for operators.

[0011] Furthermore, the infrared emitter is engaged and slidably moved with the first photoelectric sensor through a sliding groove.

[0012] By adopting the above technical solution, the infrared emitter can be easily connected to and separated from the first photoelectric sensor by means of a sliding groove and a snap-on sliding movement. This design not only simplifies the installation and disassembly process, but also allows the position of the infrared emitter to be flexibly adjusted as needed. In this way, the operator can freely adjust the height and angle of the infrared emitter according to the actual working scenario to ensure that the infrared warning line it emits can effectively cover the area that needs to be protected.

[0013] Furthermore, a plurality of mounting holes are formed on the surface of the mounting plate, and the plurality of mounting holes are linearly arranged at equal distances along the length line of the mounting plate.

[0014] By adopting the above technical solution, great convenience and flexibility are provided for the installation of the equipment. This layout allows the operator to select appropriate mounting holes for fixing according to actual installation requirements, thereby ensuring that the equipment can be stably installed in the predetermined position. At the same time, the equidistant linear arrangement of mounting holes also helps to maintain the overall aesthetics of the equipment.

[0015] Furthermore, the first photoelectric sensor and the second photoelectric sensor are both fixedly connected to the mounting hole by bolts.

[0016] By adopting the above technical solution, the first photoelectric sensor and the second photoelectric sensor can be firmly mounted on the mounting plate. This connection method not only ensures the stability and reliability of the sensors during the operation of the equipment, but also effectively prevents the sensors from shifting or falling off due to vibration or other external interference.

[0017] Furthermore, the trigger mechanism includes a fixing plate, and a Hall sensor is threadedly connected to the fixing plate.

[0018] By adopting the above technical solution, the stability and reliability of the sensor during installation can be ensured. This connection method can prevent the sensor from loosening or falling off due to vibration or other external interference, thereby ensuring the normal operation and operational stability of the trigger mechanism.

[0019] Furthermore, a plurality of threaded holes are formed on the surface of the fixing plate, and the plurality of threaded holes are linearly arranged at equal distances along the length line of the fixing plate.

[0020] By adopting the above technical solution, multiple optional positions are provided for the installation of the Hall sensor. This layout allows the operator to select the most suitable threaded hole for installation according to actual needs, thereby ensuring that the Hall sensor can accurately sense the target object.

[0021] Furthermore, a hydraulic rod is arranged at the bottom end of the main body of the hydraulic device, a stamping plate is arranged at the bottom end of the hydraulic rod, and a magnetic block is arranged on one side of the stamping plate.

[0022] By adopting the above technical solution, forging operation is realized. The design of the mechanical structure can ensure that the stamping plate has sufficient stability and accuracy during the forging process, thereby improving the forging quality and efficiency.

[0023] Furthermore, the movement track of the magnetic block is arranged in the same plane as the Hall sensor.

[0024] By adopting the above technical solution, it can be ensured that the magnetic block can accurately pass through the sensing area of ​​the Hall sensor during the movement of the stamping plate. This layout maximizes the sensing effect of the Hall sensor on the magnetic field changes of the magnetic block, thereby improving the sensitivity and response speed of the trigger mechanism.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model uses an infrared transmitter and an intelligent control mechanism. The infrared transmitter is activated only when necessary, that is, when the operator's hand enters the sensing range of the second photoelectric sensor, once the hand moves out of the sensing range, the infrared transmitter will stop working immediately. This design effectively avoids the infrared transmitter from working unnecessarily for a long time, thereby reducing the risk of visual fatigue of the operator's eyes. The reduction of visual fatigue not only helps to improve the comfort of the operator, but also maintains his alertness and work efficiency. At the same time, the functional practicality of the infrared transmitter is also improved. Since it only works when needed, its service life is extended and the maintenance cost is reduced accordingly. In addition, by reducing unnecessary infrared emission, the system can also reduce energy consumption, which is in line with the concept of green environmental protection.

[0027] 2. The utility model sets a trigger mechanism. When the operator loads or takes materials, since the second photoelectric sensor is disconnected from the external power supply, the infrared transmitter associated with it will also be in a non-responsive state. This means that the infrared transmitter will not emit an infrared warning line, thereby avoiding possible interference or hindrance to the operator, making the loading and taking processes smoother. At the same time, this control method also effectively improves the convenience of the operator in loading materials. Without the interference of the infrared warning line, the operator can move his hands and other tools more freely without worrying about triggering the alarm or shutdown function of the safety component. This not only improves work efficiency, but also reduces the risk of accidental injury due to misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] A forging machine tool protection device, such as Figure 1-Figure 4 As shown, it includes an operating table 1 and a hydraulic device body 2, a trigger mechanism 6 is arranged on one side of the hydraulic device body 2, a safety component 5 is arranged on the front surface of the operating table 1, and the safety component 5 includes a mounting plate 501, a first photoelectric sensor 502 and a second photoelectric sensor 503 are arranged on the top of the mounting plate 501, and an infrared transmitter 504 is arranged on one side of the first photoelectric sensor 502. Through the intelligent control mechanism, the infrared transmitter 504 is activated only when necessary, that is, when the operator's hand enters the sensing range of the second photoelectric sensor 503, once the hand moves out of the sensing range, the infrared transmitter 504 will stop working immediately. Such a design effectively avoids the infrared transmitter from working for a long time, thereby reducing the risk of visual fatigue of the operator's eyes. The reduction of visual fatigue not only helps to improve the comfort of the operator, but also maintains his work efficiency and concentration, thereby indirectly improving the safety of the workplace. At the same time, by improving the functional practicality of the infrared transmitter 504, the device not only ensures safety, but also optimizes the work process, and also makes the use of the infrared transmitter 504 more in line with actual work needs, thereby improving the practicality of the overall equipment and user satisfaction.

[0037] See also Figure 1 , Figure 3There are two groups of safety components 5, and the two groups of safety components 5 are arranged in a mirror image along the length line of the operating table 1, which can achieve full coverage of the working area of ​​the operating table 1. This layout ensures that during the entire working process of the forging machine, no matter which side of the operating table the operator's hand appears, it can be detected in time by at least one group of safety components 5, thereby effectively improving the equipment's safety protection capabilities for operators and reducing the risk of accidental injuries. At the same time, the mirror image arrangement of the two groups of safety components 5 also helps to improve the operating convenience and flexibility of the equipment. Since the two groups of safety components 5 are independent of each other in function but can work together, this allows the operator to work according to actual work needs.

[0038] See also Figure 4 There are multiple infrared transmitters 504, and the multiple infrared transmitters 504 are linearly arranged along the height line of the first photoelectric sensor 502, which can achieve a more accurate and comprehensive safety warning effect. This arrangement allows the infrared transmitter 504 to cover a wider area. No matter what position the operator's hand is in, it is possible to be hit by the infrared warning line emitted by at least one infrared transmitter 504, thereby effectively reminding the operator to pay attention to safety and prevent his hand from entering the dangerous area, thereby improving the equipment's safety protection ability for the operator. At the same time, the linear arrangement of multiple infrared transmitters 504 also helps to improve the reliability and stability of the equipment. Since there are multiple infrared transmitters 504 working at the same time, even if one of the transmitters fails or fails, the other transmitters can still work normally and continue to provide necessary safety warnings. This design not only enhances the fault tolerance of the equipment, but also ensures the continued effectiveness of the safety warning function, thereby improving the reliability and stability of the overall equipment.

[0039] See also Figure 3 , Figure 4 The infrared transmitter 504 slides with the first photoelectric sensor 502 through the slide groove. The infrared transmitter 504 can be easily connected to and separated from the first photoelectric sensor 502 by means of the slide groove and the engagement and sliding. This design not only simplifies the installation and disassembly process, but also allows the position of the infrared transmitter 504 to be flexibly adjusted as needed. In this way, the operator can freely adjust the height and angle of the infrared transmitter 504 according to the actual working scene to ensure that the infrared warning line it emits can effectively cover the area that needs to be protected. At the same time, the connection stability and reliability between the infrared transmitter 504 and the first photoelectric sensor 502 are ensured. During operation, the infrared transmitter 504 will not easily fall off or shift due to vibration or other external interference, thereby ensuring the continuous effectiveness of the safety warning function.

[0040] See also Figure 3A plurality of mounting holes 505 are provided on the surface of the mounting plate 501, and the plurality of mounting holes 505 are arranged linearly and equidistantly along the length line of the mounting plate 501, which provides great convenience and flexibility for the installation of the equipment. This layout allows the operator to select appropriate mounting holes 505 for fixing according to actual installation requirements, thereby ensuring that the equipment can be stably installed in a predetermined position. At the same time, the equidistant linearly arranged mounting holes 505 also help to maintain the overall aesthetics of the equipment. At the same time, the design of multiple mounting holes 505 also enhances the adaptability and expansibility of the equipment. When it is necessary to adjust or increase the functional components of the equipment, the existing mounting holes 505 can be used for rapid installation and fixing without large-scale modification or redesign of the equipment, which not only saves time and cost, but also helps to improve the overall utilization and performance of the equipment.

[0041] See also Figure 1 , Figure 3 The first photoelectric sensor 502 and the second photoelectric sensor 503 are fixedly connected to the mounting hole 505 by bolts. The first photoelectric sensor 502 and the second photoelectric sensor 503 can be firmly mounted on the mounting plate 501. This connection method not only ensures the stability and reliability of the sensor during the operation of the equipment, but also effectively prevents the sensor from shifting or falling off due to vibration or other external interference. At the same time, the bolt connection method also has high flexibility and adjustability. During the installation process, the operator can change the position and angle of the sensor by adjusting the tightness of the bolts according to actual needs to ensure that it can accurately detect the target object.

[0042] Embodiment 2:

[0043] See also Figure 1 , Figure 2 The trigger mechanism 6 includes a fixing plate 601, and a Hall sensor 603 is threadedly connected to the fixing plate 601, which can ensure the stability and reliability of the sensor during the installation process. This connection method can prevent the sensor from loosening or falling off due to vibration or other external interference, thereby ensuring the normal operation and operating stability of the trigger mechanism 6. At the same time, the threaded connection also has high flexibility and adjustability. During the installation process, the operator can adjust the position of the Hall sensor 603 by rotating it according to actual needs to ensure that it can accurately sense the magnetic block 604. This design not only improves the adaptability and practicality of the trigger mechanism 6, but also helps to improve the overall performance and work efficiency of the equipment.

[0044] See also Figure 1 , Figure 2A plurality of threaded holes 602 are provided on the surface of the fixing plate 601, and the plurality of threaded holes 602 are arranged linearly and equidistantly along the length line of the fixing plate 601, providing a plurality of optional positions for the installation of the Hall sensor 603. This layout allows the operator to select the most suitable threaded hole 602 for installation according to actual needs, thereby ensuring that the Hall sensor 603 can accurately sense the target object. At the same time, the design of the plurality of threaded holes 602 also enhances the adaptability and flexibility of the fixing plate 601. When the position or angle of the Hall sensor 603 needs to be adjusted, other unused threaded holes 602 can be used for reinstallation without replacing the entire fixing plate 601. This not only saves time and cost, but also helps to improve the overall utilization and performance of the equipment.

[0045] See also Figure 1 , Figure 2 A hydraulic rod 3 is arranged at the bottom end of the hydraulic device body 2, a stamping plate 4 is arranged at the bottom end of the hydraulic rod 3, and a magnetic block 604 is arranged on one side of the stamping plate 4 to realize the forging operation. The design of this mechanical structure can ensure that the stamping plate 4 has sufficient stability and accuracy during the forging process, thereby improving the forging quality and efficiency. At the same time, a magnetic block 604 is arranged on one side of the stamping plate 4, which can form an effective inductive coordination with the Hall sensor 603 in the trigger mechanism 6. When the stamping plate 4 moves to a specific position, the magnetic block 604 will change the magnetic field around the Hall sensor 603, thereby triggering the corresponding electrical signal to be transmitted.

[0046] See also Figure 1 , Figure 2 The movement trajectory of the magnetic block 604 is arranged in the same plane as the Hall sensor 603, which can ensure that the magnetic block 604 can accurately pass through the sensing area of ​​the Hall sensor 603 during the movement of the stamping plate 4. This layout maximizes the sensing effect of the Hall sensor 603 on the magnetic field changes of the magnetic block 604, thereby improving the sensitivity and response speed of the trigger mechanism 6. At the same time, the same-plane setting also helps to simplify the installation and debugging process of the equipment. Since the relative position relationship between the magnetic block 604 and the Hall sensor 603 is clear and fixed, the operator does not need to perform complicated spatial positioning and adjustment during the installation and debugging process, thereby saving time and cost.

[0047] The implementation principle of the utility model is as follows: first, the workpiece is placed on the operating table 1, and the hydraulic device body 2 is started. At this time, the hydraulic rod 3 pushes the stamping plate 4 to move downward. As the stamping plate 4 gradually moves downward, the magnetic block 604 on one side is driven to move. The magnetic block 604 passes through the Hall sensor 603. The Hall sensor 603 sends and receives signals, and the control center opens the current path of the second photoelectric sensor 503 by controlling the switch. During the forging operation, if a person's hand is in the sensing range of the second photoelectric sensor 503, the second photoelectric sensor 503 transmits a signal to the control center, and the control center controls the infrared transmitter 504 to work. The infrared warning lines emitted by multiple groups of infrared transmitters 504 are used to remind the operator to stay away from the working equipment, thereby improving the safety warning for the operator. If a person's hand is not in the sensing range of the second photoelectric sensor 503, the infrared transmitter 504 is controlled by the control center to stop working, thereby avoiding visual fatigue of the eyes of the external operator caused by the infrared transmitter 504 when working for a long time, thereby improving the functional practicality of the infrared transmitter 504.

[0048] When the forging operation is completed, the hydraulic rod 3 drives the stamping plate 4 to move upward, causing the magnetic block 604 on one side to pass through the Hall sensor 603 again. The Hall sensor 603 sends and receives signals, and the control center controls the second photoelectric sensor 503 to be disconnected from the external power supply through a switch, which is beneficial for the operator to load and take materials. The infrared transmitter 504 is in an unresponsive state, which improves the convenience of the operator to load materials, and further prevents the infrared transmitter 504 from being in a working state for a long time, causing visual fatigue to the operator;

[0049] When a person's hand is placed in the detection zone of the first photoelectric sensor 502, the control center controls the hydraulic device body 2 to perform an emergency stop operation, thereby providing effective safety protection for the operator.
