Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a foot pedal control system for bending machines. Background Technology

[0002] In the current system, although each foot pedal is equipped with a protective cover, this design inadvertently hinders the operator from quickly switching between the two foot pedal control functions when necessary, affecting work efficiency and operational flexibility to some extent. More importantly, the emergency stop button is located on a lever, allowing only manual activation. This layout may prevent the operator from reaching it in time during emergencies due to busy hands or distance, thus delaying the emergency stop and posing potential risks to equipment operation and personnel safety. Therefore, improving the existing dual-pedal bending machine control system to enhance its safety performance and ease of operation is particularly necessary. Utility Model Content

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figures 1 to 4 The foot pedal control system of the bending machine of this utility model is implemented in the following embodiments:

[0029] The foot pedal control system of the bending machine includes a base 100, two foot switches 200, a foot pedal protective shell 300, a pull rod 400, and an emergency stop device 500.

[0030] The base 100 serves to install and support the entire system. It increases the contact area between the foot pedal control system and the ground, and its weight lowers the overall center of gravity, making it less prone to wobbling or tipping during placement and operation, thus improving overall stability. For added stability, the base 100 can be secured to the bottom surface with countersunk screws.

[0031] Two foot switches 200 are arranged side-by-side on the upper surface of the base 100. Each foot switch 200 acts as a prime mover, and pressing the foot pedal controls the bending machine's upward and downward movements. A foot pedal protective shell 300 covers the two foot switches 200. The front side of the protective shell 300 has a foot pedal operation hole 310, allowing the foot to move left and right within the shell. The foot operation hole 310 corresponds to each of the two foot switches 200. The foot can be inserted through the foot pedal operation hole 310 and moved left and right within the protective shell 300 to switch control of the two foot switches 200, achieving rapid switching. In contrast, existing bending machine foot pedal control systems use separate protective shells for each foot switch 200. Since each protective shell protects its corresponding foot switch 200, it is usually necessary to first remove the foot from the protective shell of one foot switch 200 and then insert the foot into the protective shell of the other foot switch 200 to control the other foot switch 200. Therefore, this application solves the problem of inflexible and inconvenient operation in the past. This application is equipped with a protective cover, which can protect the pedal 220, reduce the entry of iron filings into the structure of the pedal 220, and control the pedal 220 by simply moving the foot left or right when controlling the rise and fall, making switching control convenient.

[0032] The lower end of the pull rod 400 is fixed to the side of the foot pedal protective shell 300 by multiple screws. The upper end of the pull rod 400 is provided with a handle 410, which extends laterally. The outer side of the handle 410 is covered with a protective sleeve, which can be made of rubber, silicone, or other materials to improve grip comfort. The emergency stop device 500 is provided with an emergency stop button 510, which is located on the upper surface of the foot pedal protective shell 300. The main body of the emergency stop device 500 is located inside the foot pedal protective shell 300. The foot pedal protective shell 300 also protects the emergency stop device 500. In case of emergency stop, the emergency stop button 510 can be pressed with the foot, without the need to control the emergency stop button 510 by hand. Both the foot pedal and the emergency stop are controlled by the foot, which can improve the operator's reaction speed and improve safety performance.

[0033] This application significantly improves the safety and convenience of bending machine operation by optimizing the structure and control method of the foot switch 200. Specifically, the added protective cover effectively prevents foreign objects such as iron filings from entering the pedal 220, ensuring long-term stable operation of the mechanism; the innovative left-right movement foot control design makes the switching between rising and falling movements more direct and rapid, allowing operators to achieve precise control without adjusting their foot position, greatly improving work efficiency; at the same time, the emergency stop function is integrated into the foot pedal area, triggering an emergency stop with a single foot movement, avoiding the delay of hand operation in traditional designs, reducing the emergency stop response time by more than 50%, and providing double safety protection for operators. This integrated foot control solution not only frees the operator's hands but also significantly reduces the risk of misoperation through an ergonomic layout, making it particularly suitable for high-intensity, high-frequency industrial production scenarios.

[0034] Furthermore, the outer side of the foot pedal protective shell 300 is provided with an upward indicator 320 and a downward indicator 330. The upward indicator 320 and the downward indicator 330 are respectively set for the two foot pedal switches 200, which makes it easy to distinguish the functions of the two foot pedal switches 200 and prevents incorrect operation.

[0035] Furthermore, the foot pedal protective shell 300 is provided with a cable outlet hole 340, and the cable through hole on the rear surface is provided with an internal thread, which can be installed with a corrugated pipe connector to lead out the cable and connect it to the main unit.

[0036] Furthermore, combined Figure 4 In detail, the foot switch 200 consists of a foot base 210 and a pedal 220 as its key structures. The pedal 220 is rotatably mounted on the foot base 210. A return spring 230 is installed between the bottom of the pedal 220 and the foot base 210. This return spring 230 provides a continuous and stable upward elastic force to the pedal 220, ensuring that the pedal 220 automatically returns to its initial position when no external force is applied.

[0037] To enable flexible adjustment of the pedal 220's tilt angle and better suit the needs of different operators, an angle adjustment mechanism is specifically designed between the footrest base 210 and the pedal 220. Specifically, this angle adjustment mechanism includes a slotted hole on the pedal 220, an adjusting screw 240 located on the footrest base 210, and an eccentric nut 250 threadedly engaged with it. The adjusting screw 240 passes through the slotted hole on the pedal 220, and the eccentric nut 250 is threaded onto the adjusting screw 240 and abuts tightly against the surface of the pedal 220.

[0038] In actual operation, when the operator steps on pedal 220, pedal 220 moves downward along adjusting screw 240, compressing return spring 230. When the operator releases pedal 220, the pedal 220 returns to its original position under the strong elastic force of return spring 230. However, due to the resistance of eccentric nut 250, pedal 220 cannot rise indefinitely; it stops moving after reaching a specific position. When it is necessary to adjust the maximum tilt angle of pedal 220, simply rotate eccentric nut 250, moving it relative to adjusting screw 240. As the position of eccentric nut 250 changes, the upward return stroke of pedal 220 under the action of return spring 230 also changes accordingly, thus achieving the adjustment of the maximum tilt angle of pedal 220.

[0039] This design, which adjusts the tilt angle of pedal 220 via an angle adjustment mechanism, offers significant advantages and practical benefits. It allows for flexible adjustment of the pedal 220's tilt angle based on the leg length and operating habits of operators of varying heights, making pedaling more comfortable and effortless, effectively reducing operator fatigue. Simultaneously, a suitable pedal 220 tilt angle improves operational accuracy and stability, reduces the risk of misoperation, and thus enhances the overall operational performance and safety of the dual-pedal 220 bending machine control system.

[0040] Furthermore, the adjusting screw 240 is fitted onto an elastic washer, which is located between the eccentric nut 250 and the surface of the pedal 220, to absorb vibration of the pedal 220 and prevent the threads from loosening. The pedal 220 is a carbon fiber component, which reduces weight by 40% to 50% compared to traditional steel structures while maintaining high strength and improving operating comfort. The tread surface of the pedal 220 is provided with anti-slip threads, specifically made of diamond-patterned anti-slip steel plate, making it less prone to slipping.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
