Description

Technical Field

[0001] The invention relates to the technical field of grounding flat iron processing, and in particular to a small portable electric bending machine for grounding flat iron. Background Art

[0002] As an important component in the power system, grounding flat iron is widely used in the laying and maintenance of grounding devices. Due to the characteristics of high strength, high hardness and large cross-sectional size, its bending processing places high demands on the portability, efficiency and precision of the tool.

[0003] At present, in the field operation of power system, the bending work of grounding flat iron mainly relies on manual tools or mechanical devices. Although the traditional manual bending tools are light, they are laborious to operate and it is difficult to ensure the accuracy of the bending angle. Mechanical devices such as hydraulic bending equipment have higher precision and efficiency, but they are large in size and heavy in weight, which is not convenient for use in complex outdoor environments. These limitations increase the labor intensity of operators and reduce work efficiency.

[0004] In recent years, the application of electric bending technology in the field of metal processing has been gradually promoted, and its automation and intelligent characteristics have provided a new solution for improving the bending efficiency of grounded flat irons. However, most of the existing electric bending machines are designed for industrial workshops. They are bulky and have single functions, which makes it difficult to meet the portability requirements of power field operations. Therefore, it is of great significance to develop a small portable grounded flat iron electric bending machine that can not only meet the precise bending requirements, but also has the characteristics of portability and intelligence. Summary of the invention

[0005] The purpose of the present invention is to provide a small portable grounded flat iron electric bending machine, which is small and portable, can meet the needs of precise bending, and has the characteristics of portability and intelligence.

[0011] Furthermore, the driving module includes a supporting frame, which is detachably mounted on a base and is provided with a brushless motor, a transmission mechanism and a power module. The transmission mechanism is a worm and worm gear reduction mechanism. The output shaft of the brushless motor is connected to the worm of the worm and worm gear reduction mechanism. The worm wheel of the worm and worm gear reduction mechanism is meshed with a rack for driving the rack to move up and down. The lower end of the rack is connected to a movable pressure head.

[0026] The hazardous area dry sensing submodule is also used to re-collect new environmental image information of the surrounding environment through the pan-tilt camera when the bending model predicts and analyzes the pressure size and speed of the active pressure head, and re-analyze the current working environment as a non-restricted area based on the new environmental image information and positioning information.

[0027] Furthermore, the support legs are designed with a rotating thread type, and the height can be adjusted by rotation to adapt to different ground height differences or uneven conditions.

[0028] Furthermore, a non-slip rubber pad is provided on the base.

[0029] Principles and advantages:

[0030] 1. The overall design of the support module is foldable. The support legs can be folded and stored under the base when not in use, reducing the space occupied, so that it can be loaded into a toolbox or a backpack-type portable device, making it easier to carry and transport the equipment. In addition, the overall module is light and easy for one person to carry. The support legs are designed with a rotating thread. The height can be adjusted by rotating to adapt to different ground height differences or uneven conditions, making it convenient to carry and use when going out. Such as slopes, gravel floors, etc. The non-slip rubber pad improves the stability of the device on smooth or wet surfaces. A level is integrated on the base, and the user can ensure that the device is in a horizontal state by adjusting the support legs, thereby improving the accuracy of the bending operation.

[0031] 2. Bending module: It can accurately control the bending angle and bending radius of the grounding flat iron, and the mold can be replaced to adapt to different specifications of grounding flat iron. The movable pressure head is powered by the drive module and moves downward through the mechanical transmission mechanism to apply uniform bending pressure to the grounding flat iron. The fixing fixture is used to stabilize the position of the flat iron to avoid sliding or offset during the bending process. The replaceable mold is designed as a replaceable structure, and different mold specifications can be adapted to a variety of grounding flat iron sizes and shapes to meet the needs of different construction scenarios. The replaceable mold can adopt a conventional modular buckle design to achieve detachable installation, which can be quickly replaced within seconds, avoiding cumbersome threaded connections or tool disassembly and assembly. The angle sensor ensures the accuracy of the bending angle, and the pressure sensor is used to detect the pressure applied to the flat iron to prevent material damage or mold wear due to excessive force. The output of the drive module is adjusted through negative feedback to achieve dynamic bending control. The bending module adopts a transmission method combining worm and worm gear and linear guide. The worm and worm gear structure can provide a strong reduction ratio and efficiently convert the rotational force output by the motor into the vertical movement of the pressure head. This design not only improves the operating accuracy, but also prolongs the overall service life of the module. It is also lightweight, so it is easy to put into a tool box or a backpack-type portable device, making it easy to carry and transport the equipment.

[0032] 3. Drive module: Equipped with a high-power brushless motor, combined with a worm gear reduction mechanism to achieve efficient power output. The brushless motor is the main power source, providing efficient and stable rotational power. The worm gear reduction mechanism converts high-speed rotation into high-torque output, driving the active pressure head of the bending module to complete the bending operation. The support frame is made of high-strength and lightweight materials, which firmly connects the drive module to the bending module and reduces the overall weight of the equipment. The brushless motor is powered by a built-in battery pack and supports wireless operation. Provide a stable power source to ensure a smooth and precise bending process.

[0033] 4. The control module receives the set parameters of the bending angle and pressure in real time, and dynamically adjusts the motor output. At the same time, the negative feedback loop can ensure that the output torque matches the actual demand to avoid damage to the equipment due to overload or excessive bending. In addition, the drive module also integrates a temperature sensor to monitor the operating temperature of the motor and transmission mechanism in real time. When the set temperature is exceeded, the power is automatically reduced or the operation is suspended to prevent the equipment from overheating. The drive module shell is made of high-efficiency thermal conductive material, and heat dissipation holes and air duct structures are designed to effectively reduce the internal temperature when the equipment is working for a long time, thereby extending the service life of the motor and transmission mechanism. There is also an overload protection function, which automatically reduces the output or suspends the operation of the equipment when it detects that the load of the drive module exceeds the rated range.

[0034] 5. The control module is designed with an open interface, allowing new sensors or functional modules to be added later, such as camera pan / tilt and GPS positioning module, to meet special needs in different scenarios. Especially for safety needs, the control module in this solution analyzes the current working environment based on positioning information and environmental image information. If the current working environment is analyzed to be a restricted area, a shutdown signal is generated; if the current working environment is analyzed to be a non-restricted area, a normal startup signal is generated. When the normal startup signal is obtained, the pan / tilt camera is controlled to collect the bending image information of the flat iron, and whether the bent flat iron rebounds according to the bending image information is analyzed. If so, the bending conditions are obtained, and the bending conditions include the pressure and speed of the active pressure head; the rebound amount is analyzed, and the pressure and speed of the active pressure head are predicted and analyzed according to the rebound amount and the bending model; the current environment is analyzed to see if it is still safe through the pressure and speed. Re-analyze the current working environment as a non-restricted area. Through multi-level safety protection design, the safety module effectively reduces the risk of equipment operation, provides a safer and more reliable working environment for operators, and ensures that the equipment can operate stably for a long time in various complex environments.

[0036] Figure 2 It is a schematic diagram of the structure of a small portable grounded flat iron electric bending machine. DETAILED DESCRIPTION

[0037] The following is further described in detail through specific implementation methods:

[0038] Embodiment 1

[0039] A small portable ground flat iron electric bending machine, basically like Figure 1 , Figure 2As shown, it includes a bending main body structure and peripheral devices, and the bending main body structure includes: a support module, a bending module, a driving module, a control module and a safety module. The peripheral devices include a touch display screen, a pan-tilt camera, a GPS positioning module and a communication module. The control module is connected to a handheld terminal through the communication module, and the handheld terminal communicates remotely with the control module through the App.

[0040] Support module: includes an aluminum alloy base and adjustable height support legs, the support legs are folded and stored under the base; a level is installed on the base; the base is made of high-strength aluminum alloy material, which not only ensures strength but also reduces weight. An anti-slip rubber pad is set on the base to enhance stability and prevent the device from sliding during operation. A plurality of reserved mounting holes can be set under the base to fix the device to the ground or workbench when necessary, so as to be used in combination with other fixing devices (such as an operating table) to further enhance the stability of the device. An adjustable support leg is set at each of the four corners of the base, for a total of 4. Adjustment method: The support leg adopts a rotating thread design, and the height is adjusted by rotation to adapt to different ground height differences or uneven conditions. Material: The support leg is made of retractable aluminum alloy with a built-in locking device to ensure stable support. Using the level, the user can specifically ensure that the device is in a horizontal state by adjusting the support legs, ensuring that the device is evenly stressed during the bending process, thereby improving the accuracy of the bending operation. In other embodiments, the base can be added with an anti-vibration design. For example, vibration-absorbing materials are filled inside the base to reduce the impact of vibration generated when the motor is running on the bending operation. The spirit level can be changed to an integrated electronic leveling system, which enables one-touch leveling via sensors and automatically retractable support legs.

[0041] Bending module: including a movable pressure head, an angle sensor, a pressure sensor, a fixing fixture and a replaceable die. The replaceable die is detachably mounted on the base. The fixing fixture is used to stabilize the relative position of the flat iron on the replaceable die. The movable pressure head is used to bend the flat iron. The angle sensor and the pressure sensor are used to monitor the bending angle and the extrusion pressure of the movable pressure head in real time. The movable pressure head is powered by the driving module and moves downward through the mechanical transmission mechanism to apply uniform bending pressure to the grounded flat iron. The force sensor is used to detect the pressure applied to the flat iron. It is set between the aluminum alloy base and the replaceable die to prevent material damage or die wear due to excessive force. In the bending module, the relative position between the movable pressure head and the fixing fixture is precisely calibrated to ensure that the material is evenly stressed during operation. A limit switch is designed on the base to prevent the pressure head from pressing down beyond the preset position to avoid damage to the equipment and materials. In addition, a heat-insulating coating is added to the surface of the module to prevent the surface temperature from being too high due to continuous operation of the equipment, which affects the safety of use.

[0042] Drive module: used to drive the active pressure head, detachably mounted on the base; the drive module includes a support frame, which is detachably mounted on the base, and is provided with a brushless motor, a transmission mechanism and a power module (lithium battery pack), the transmission mechanism is a worm gear reduction mechanism, the output shaft of the brushless motor is connected to the worm of the worm gear reduction mechanism, the worm wheel of the worm gear reduction mechanism is meshed with a rack for driving the rack to move up and down, the lower end of the rack is connected to the active pressure head, and the power module is used to power the brushless motor. In this embodiment, the transmission mechanism adopts a transmission method combining a worm gear and a linear guide. The worm gear structure can provide a strong reduction ratio and efficiently convert the rotational force output by the brushless motor into the vertical movement of the pressure head. And it has a self-locking function: the natural structural characteristics of the worm gear enable the active pressure head to maintain the current position when the power supply is stopped, avoiding rebound or loosening. The linear guide ensures the stability of the downward movement of the rack, thereby ensuring the stability of the movement of the active pressure head and avoiding deviation or shaking. This design not only improves the operating accuracy, but also extends the overall service life of the module. The brushless motor is powered by a built-in lithium battery pack and supports wireless operation.

[0043] The power module is composed of a high-capacity lithium battery pack and has the following features:

[0044] Long battery life: A single charge can support continuous work and meet the needs of outdoor operations.

[0045] Fast charging function: Uses fast charging technology to quickly charge the battery.

[0046] Safety: The battery pack has built-in overcharge, over-discharge and overheat protection circuits to extend battery life and ensure safe use.

[0047] Portability: The battery pack is modularly designed and can be quickly disassembled and replaced, making it convenient for long-term operation.

[0048] The support frame of the driving module is made of high-efficiency heat-conducting materials and is provided with heat dissipation holes and air duct structures; when the equipment is working for a long time, the internal temperature is effectively reduced, and the service life of the motor and transmission mechanism is extended. The housing is also waterproof and dustproof, and can adapt to harsh outdoor working environments. A temperature sensor is provided at the connection between the support frame and the brushless motor, and the temperature sensor is used to detect temperature information and send it to the control module. The angle sensor collects the position information of the active pressure head in real time. In this embodiment, a rolling wheel is installed on the shaft of the angle sensor, and the rolling wheel is close to the side of the rack. The position information of the active pressure head can be analyzed through the angle data of the angle sensor.

[0049] Control module: used to obtain the setting parameters of the bending angle and the extrusion pressure, control the driving module to make the active pressure head bend the flat iron according to the setting parameters of the bending angle and the extrusion pressure, and monitor the bending angle and the extrusion pressure of the active pressure head in real time to adjust the output of the driving module through negative feedback. The control module includes the following submodules:

[0050] Remote operation submodule: used for remote communication with the handheld terminal through the communication module, used for setting the bending angle and pressure, and also used for status monitoring, the status includes the battery power of the power module, temperature information, current bending angle and bending progress. The communication module is a WiFi module and / or a Bluetooth module.

[0051] Abnormal monitoring submodule: It is used to actively stop the device and issue an alarm message when it detects that the drive module is overloaded, overheated or operating incorrectly.

[0052] The touch screen is used by the user to set the bending angle and pressure, and is also used to view the real-time device status, which includes the battery power of the power module, temperature information, current bending angle, and bending progress. The operating parameters of the drive module are adjusted in real time to achieve intelligent operation and ensure the accuracy and consistency of the bending process. The control module focuses on improving the user experience, providing an intuitive interface design and voice broadcast function. When the device completes the bending operation or detects an abnormality, it will notify the user through voice or prompt tone to avoid the operator frequently checking the screen. In addition, the touch screen uses an anti-reflective coating to ensure visibility in the sun and adapt to outdoor environments.

[0053] The control module uses a high-performance microprocessor to run an embedded control program to manage the operation logic of the entire device. The microprocessor processes sensor data through an integrated algorithm and adjusts the brushless motor output parameters in real time to ensure the accuracy of the bending angle and pressure. The microprocessor also has an abnormality monitoring function that can actively stop the device from running to protect the safety of equipment and personnel when overload, overheating or operating errors are detected.

[0054] Safety module: The safety module is used in conjunction with the abnormal monitoring submodule, specifically including: limit switch, overload protection device, temperature protection device, emergency stop button and alarm device;

[0055] The limit switch is installed at the upper and lower travel limit positions of the movable pressure head. When the movable pressure head reaches the preset upper or lower limit position, the limit switch will automatically cut off the power supply of the drive module to prevent the pressure head from overshooting or mechanical parts from being damaged. This mechanical protection device has high reliability and can provide basic safety protection even if the main control system of the equipment fails.

[0056] The overload protection device is used to monitor the output torque of the brushless motor in real time through the force sensor. When it is detected that the load exceeds the rated range (such as due to excessive material thickness or misoperation), the protection device immediately reduces the power of the brushless motor or stops running to protect the transmission mechanism and the motor from damage. At the same time, the control module will display an overload prompt message on the touch screen to remind the operator to adjust the operation.

[0057] The temperature protection device is used to automatically trigger the power reduction or suspension function when the temperature information exceeds the safety threshold, and continue to work after returning to a safe temperature; the temperature information is collected by the temperature sensor and distributed in the key parts of the motor, worm gear and control module. After the equipment returns to a safe temperature, it can continue to work to avoid component aging or equipment damage caused by overheating.

[0058] The emergency stop button is used to cut off the power supply of the equipment immediately when an emergency occurs (such as abnormal shaking of the equipment or jamming of flat iron materials); it is usually installed on the top or side of the equipment to facilitate the operator to trigger it quickly. The operator can immediately cut off the power supply of the equipment by pressing the button, terminate all actions, and ensure the safety of people and equipment. The alarm device warns of abnormal equipment status through sound, light and screen prompts. Specifically, the buzzer sounds, the LED light flashes, and detailed fault information is displayed on the touch screen.

[0059] The control module can detect the operating status of the equipment in real time. When the following abnormal conditions are found, the module will immediately issue a warning and take protective measures:

[0060] Overload protection: When it is detected that the load of the drive module exceeds the rated range, the output is automatically reduced or the equipment operation is suspended.

[0061] Overheat protection: When the temperature sensor detects that the device temperature is too high, it automatically switches to low power mode or stops running.

[0062] Fault diagnosis: The control touch display screen pops up detailed fault information, which is convenient for users to handle in time.

[0063] The operation process of this program:

[0064] Fix the grounded flat iron in the fixture of the mold and enter the bending angle and force parameters on the touch screen.

[0065] Start the equipment, the drive module starts working, and the active pressure head moves downward under the power of the brushless motor to complete the bending operation of the flat iron. The control module monitors the bending progress in real time through the sensor and displays it on the screen. After the bending is completed, the equipment automatically resets. For bending angle control: the angle sensor collects the position information of the active pressure head in real time, and adjusts the brushless motor output through negative feedback closed-loop control to ensure the accuracy of the bending angle.

[0066] This solution divides the equipment into support module, bending module, drive module, control module and safety module, with compact structure and independent functions. Its advantages: The modular structure is easy to transport, disassemble and maintain, and can be quickly replaced or upgraded according to the operation requirements. The mold is replaced by a quick buckle mechanism, without the assistance of tools, and can be completed by one person. Moreover, the replaceable molds of multiple specifications have a unified interface and are compatible with grounding flat irons of different sizes. The replacement process is simple and fast, greatly improving the operation efficiency.

[0067] Embodiment 2

[0068] The difference between the second embodiment and the first embodiment is that the control module is designed with an open interface, allowing the subsequent addition of new sensors or functional modules, such as a camera pan / tilt and a GPS positioning module, to meet the special needs of different scenarios. Specifically, the following modules are included:

[0069] Dangerous area dry sensor module: used to obtain the positioning information of the GPS positioning module and the environmental image information collected by the PTZ camera, and analyze the current working environment based on the positioning information and environmental image information. If the current working environment is analyzed to be a restricted area, a shutdown signal is generated; if the current working environment is analyzed to be a non-restricted area, a normal start-up signal is generated;

[0070] Bending image analysis submodule: used to control the pan-tilt camera to collect the bending image information of the flat iron when a normal power-on signal is obtained, and analyze whether the bent flat iron rebounds according to the bending image information. If so, the bending conditions are obtained, and the bending conditions include the pressure and speed of the active pressure head; the rebound amount is analyzed, and the pressure and speed of the active pressure head are predicted and analyzed based on the rebound amount and the bending model; the bending model adopts a conventional image prediction and analysis model, such as a convolutional neural network (CNN), a long short-term memory network (LSTM), a generative adversarial network (GAN) and other neural network models.

[0071] The hazardous area dry sensing submodule is also used to re-collect new environmental image information of the surrounding environment through the pan-tilt camera when the bending model predicts and analyzes the pressure size and speed of the active pressure head, and re-analyze the current working environment as a non-restricted area based on the new environmental image information and positioning information.

[0072] The control module of this scheme is designed with an open interface, and the camera pan and GPS positioning module are added to meet the safety requirements. In this scheme, the control module analyzes the current working environment according to the positioning information and the environmental image information. If the current working environment is analyzed to be a restricted area, there may be unsafe factors (such as a large number of onlookers, or in an area with a large flow of people), a shutdown signal is generated; if the current working environment is analyzed to be a non-restricted area, indicating safety, a normal start-up signal is generated. When the normal start-up signal is obtained, the pan-tilt camera is controlled to collect the bending image information of the flat iron, and whether the bent flat iron rebounds according to the bending image information is analyzed. If it does, the bending conditions are obtained, and the bending conditions include the pressure and speed of the active pressure head; the rebound amount is analyzed, and the pressure and speed of the active pressure head are predicted and analyzed according to the rebound amount and the bending model; if the rebound amount is large, it may be necessary to increase the pressure and speed of the active pressure head, and then analyze whether the current environment is still safe through the pressure and speed, because the pressure and speed increase, the degree of danger of processing will also increase, so it is not suitable to have too many people around the device, and the analysis of the surrounding environment is very important. Then, by re-analyzing whether the current working environment is a non-restricted area or a restricted area, targeted measures are taken to ensure safe processing. Through multi-level safety protection design, the safety module effectively reduces the risk of equipment operation, provides operators with a safer and more reliable working environment, and ensures that the equipment can operate stably for a long time in various complex environments.

The ordinary technicians in the relevant field know all the common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date.
