Description

Technical Field

[0001] The present invention relates to the technical field of bending machines, in particular to a high-precision bending machine with a warning function. Background Art

[0002] Press brakes are widely used in the metal processing industry, primarily for bending metal sheets to meet the manufacturing needs of various products. However, existing press brakes have some problems and deficiencies in actual use, which limit their full performance and the improvement of processing efficiency.

[0003] Traditional press brake feeding methods typically require manual assistance using levers. Operators manually place the metal sheet into the feed position and use leverage to push the sheet into the bending area. This method is not only labor-intensive and prone to operator fatigue, but also inefficient and unsuitable for high-volume, continuous production. Manual feeding is also prone to problems such as inaccurate feeding and sheet deviation, which in turn affect the precision and quality of the bending process.

[0004] In particular, existing press brakes often rely on manual calibration for module positioning. Operators must manually adjust the module position according to processing requirements to ensure accurate bending. This manual calibration process is tedious and prone to errors. Inaccurate module positioning can lead to quality issues such as deviations in bending angles and inconsistent dimensions. In severe cases, re-processing may be necessary, increasing production costs and time.

[0005] Conventional press brakes typically have internal lighting with a fixed brightness that cannot be adjusted to suit the lighting requirements of the actual processing environment. In dimly lit environments, the operator's vision is easily affected, making it difficult to accurately observe the processing process, increasing operational difficulty and the risk of error. Excessively bright lighting can cause glare, affecting the operator's visual comfort.

[0006] Therefore, a high-precision bending machine with a warning function is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, a bending machine is provided to make improvements and innovations in feeding, module positioning, material corrosion resistance and lighting adjustment, so as to improve its production efficiency, processing accuracy and service life, and meet the modern metal processing industry's demand for efficient, precise and reliable equipment.

[0008] The technical solution adopted by the present invention to solve its technical problems is: a high-precision bending machine with a warning function, including a frame, characterized in that: the front end of the frame is provided with a bending mechanism for bending metal sheets, the lower end of the frame is provided with two opposite feeding mechanisms, the two feeding mechanisms can drive the metal sheets to rise and fall, the lower end of the frame is provided with a module positioning mechanism, the feeding mechanism moves and positions on the module positioning mechanism, the upper end of the frame is provided with an outer shell, and the outer shell is provided with a lighting component.

[0009] Preferably, the bending mechanism includes an upper bending die head, a lower bending die head and a driving member that are relatively arranged. The driving member is fixedly installed inside the frame, and the lower end of the driving member is transmission-connected to the upper bending die head for bending the metal sheet.

[0010] Preferably, the feeding mechanism includes a feeding die head and a lifting device, wherein the feeding die head is connected to the lifting device, and the lifting device is used to drive the feeding die head to rise and fall; The lifting device includes a mounting block, which is connected to the module positioning mechanism. A moving column is sleeved inside the mounting block. The upper end of the moving column is connected to the feed die head. A threaded hole is provided at the lower end of the moving column. The lower end of the moving column is threadedly connected to a screw rod 1 through the threaded hole. The lower end of the screw rod 1 passes through and is limited to the lower surface of the mounting block and is fixedly connected to a rotating handle.

[0011] Preferably, a scale line is provided on one side of the moving column.

[0012] Preferably, the module positioning mechanism includes a positioning block and a positioning drive device. A set of slide rails 1 is provided on the frame. The positioning block can be slidably set on the slide rail 1 and can be connected and fixed to the slide rail 1 at any position of its sliding track. The number of the positioning blocks is two, and the positioning drive device is fixedly installed on the two positioning blocks. The two positioning drive devices are arranged opposite to each other.

[0013] Preferably, any of the positioning drive devices includes a T-plate, the T-plate is fixedly mounted on the positioning block, a set of slide rails 2 is provided on the inner side of the T-plate, a connecting block is slidably connected to the slide rails 2, a motor bracket is provided on the outer side of the T-plate, the motor is fixedly mounted on the corresponding motor bracket, the output end of the motor passes through the motor bracket and is coaxially connected to a screw rod 2, the screw rod 2 is threadedly connected to one end of the connecting block, and the other end of the connecting block is slidably connected to the slide rail 2; Preferably, the connecting block is concave-shaped, and the inner side of the connecting block is fixedly connected to the feeding mechanism.

[0014] Preferably, the lighting mechanism includes a lighting lamp and an indicator light. The lighting lamp is arranged inside the bending machine and the lighting direction is vertically downward. The indicator light is arranged on the outer surface of the outer shell.

[0015] Preferably, the indicator light is provided with a red light, a green light and a yellow light, the red light indicates a stopped working state, the green light indicates a running state, and the yellow light indicates a standby state.

[0016] The beneficial effects of the present invention are: 1. The feed die head is driven up and down by a lifting device in the feed mechanism, facilitating the feeding of metal sheets. This improvement breaks away from the traditional bending machine's reliance on manual lever feeding, significantly reducing the operator's labor intensity and making the operation process easier and more convenient. At the same time, it ensures the continuity and stability of feeding, avoiding potential pauses and deviations in feeding, thereby significantly improving production efficiency. This advantage is particularly evident in large-scale production, effectively shortening the production cycle and bringing higher economic benefits to the company.

[0017] The module positioning mechanism utilizes the concave design of the connecting block and works in conjunction with the motor to achieve automatic feeding and positioning. This not only eliminates the tedious step of manually correcting module position, but also significantly improves positioning accuracy and efficiency. Accurate module positioning is a key factor in ensuring bending process quality. The automatic positioning function enables the press brake to quickly and accurately adjust to the optimal position for each operation, reducing scrap caused by inaccurate positioning, thereby improving overall production efficiency and product quality.

[0018] The lighting mechanism features three adjustable levels, and the indicator light has a three-color warning function. Operators can flexibly adjust the brightness of the lighting according to the actual lighting conditions of the processing environment and monitor the operating status of the bending machine in real time. In a dimly lit workshop, the lighting can be adjusted to its brightest setting to provide sufficient light for the bending process, allowing operators to clearly observe the details of the processing and ensure the accuracy and safety of the processing. In environments with more abundant light, the brightness of the lighting can be appropriately reduced to avoid visual fatigue caused by excessive light on the operator. This humanized lighting adjustment design not only improves the operator's work comfort, but also helps reduce operational errors caused by visual fatigue, further ensuring production quality and safety.
