Description

Technical Field

[0001] This utility model relates to the field of safety light curtain protection technology, specifically to a safety light curtain protection device for a servo bending machine. Background Technology

[0002] A servo bending machine is a CNC device that uses a servo motor to achieve high-precision bending. It is widely used in sheet metal processing, especially in the automotive, electronics, and building decoration industries for precision bending of metal sheets. The operator inputs parameters such as bending angle, length, and material thickness, and the system generates processing instructions. A high-precision servo motor controls the movement of the hydraulic cylinder or ball screw, achieving the vertical reciprocating motion of the slide (upper die). The pressure control system adjusts the working pressure of the hydraulic cylinder to ensure uniform stress on the sheet metal.

[0003] The workpiece clamping system fixes the sheet metal to prevent displacement during bending. A safety light curtain protection device is generally installed at the feed inlet of the servo bending machine. The safety light curtain consists of a transmitter and a receiver, which are installed opposite each other to form a light curtain composed of multiple infrared beams. When an object blocks any beam of light, the receiver immediately identifies it and outputs a signal to the light curtain controller, triggering the equipment to stop or alarm.

[0004] The existing safety light curtain protection device for servo bending machines is not convenient for adjusting the height and angle of the safety light curtain. It is suitable for servo bending machine feed inlets of different heights and angles, but cannot meet different usage requirements. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a safety light curtain protection device for servo bending machines. The safety light curtain protection device for servo bending machines allows for easy adjustment of the height and angle of the safety light curtain, and is suitable for servo bending machine feed inlets of different heights and angles, meeting different usage requirements.

[0006] The technical solution adopted by this utility model to solve its technical problem is a safety light curtain protection device for a servo bending machine, including a mounting base frame, a support vertical plate and a dust cover. The top two sides of the mounting base frame are welded with support vertical plates, and the top of the support vertical plates are connected by screws to install the dust cover. Each support vertical plate has a strip-shaped sliding hole at its upper end, and a sliding screw passes through the strip-shaped sliding hole. One end of the sliding screw is fitted with a sliding block through a screw hole, and a longitudinal support plate is welded to one end of the sliding block. A servo motor is mounted on one side of the longitudinal support plate through a mounting base. The output shaft of the servo motor passes through the longitudinal support plate and is connected to a grating positioning vertical plate by bolts. Safety gratings are installed on the inner side of the grating positioning vertical plate by screws.

[0007] By adopting the above technical solution, the safety light curtain protection device for servo bending machines is easy to adjust in height and angle, and is suitable for servo bending machine feed inlets of different heights and angles, meeting different usage requirements.

[0008] Specifically, a grating controller is mounted on the top of the dust cover by screws, and the output end of the grating controller is electrically connected to the input end of the safety grating by wires.

[0009] Specifically, a servo motor controller is mounted on one end of the servo motor by screws, and the output end of the servo motor controller is electrically connected to the input end of the servo motor by wires.

[0010] By adopting the above technical solution, the rotation angle of the servo motor is automatically controlled by the servo motor controller, thereby driving the grating positioning vertical plate to rotate and adjusting the angle of the safety grating.

[0011] Specifically, mounting plates are welded to both sides of the bottom end of the mounting frame, and mounting holes are provided on the mounting plates.

[0012] Specifically, a locking nut is fitted at the other end of the sliding screw, and the locking nut is located outside the strip-shaped sliding hole.

[0013] Specifically, a scale is provided on the outer side of the supporting vertical plate and close to the strip-shaped sliding hole.

[0014] By adopting the above technical solution, and by observing the scale, it is easy to adjust the sliding screw to different heights, so that the safety grating on the inner side of the grating positioning vertical plate is adjusted to the same height as the feed inlet of the servo bending machine.

[0015] The beneficial effects of this utility model are: (1) The safety light grid protection device for a servo bending machine described in this utility model uses the mounting holes on the mounting plate and the matching bolts to facilitate the installation of the safety light grid protection device on one side of the feed inlet of the servo bending machine. The servo motor controller automatically controls the rotation angle of the servo motor, thereby driving the light grid positioning vertical plate to rotate and adjust the angle of the safety light grid so that the safety light grids on both sides are parallel to the feed inlet of the servo bending machine. The locking nut is loosened to allow the sliding screw to slide in the strip-shaped sliding hole. At the same time, the scale is viewed to facilitate the adjustment of the sliding screw to different heights, so that the safety light grid on the inner side of the light grid positioning vertical plate is adjusted to the same height as the feed inlet of the servo bending machine.

[0016] (2) The safety light curtain protection device for a servo bending machine described in this utility model utilizes a safety light curtain consisting of a transmitter and a receiver, which are installed opposite each other to form a light curtain composed of multiple infrared beams. When an object blocks any beam of light, the receiver immediately identifies and outputs a signal to the light curtain controller, triggering the equipment to stop or alarm, thus preventing further danger.

Figure 1-3 As shown, the safety light curtain protection device for a servo bending machine according to this utility model includes a mounting base frame 1, a support vertical plate 5, and a dust cover 6. The support vertical plate 5 is welded to the top two sides of the mounting base frame 1. The dust cover 6 is installed between the tops of the support vertical plate 5 by screws. Each support vertical plate 5 has a strip-shaped sliding hole 13 at its upper end, and a sliding screw 14 passes through the strip-shaped sliding hole 13. One end of the sliding screw 14 is fitted with a sliding block 8 through a screw hole, and a longitudinal support plate 4 is welded to one end of the sliding block 8. A servo motor 2 is mounted on one side of the longitudinal support plate 4 through a mounting base. The output shaft of the servo motor 2 passes through the longitudinal support plate 4 and is connected to a grating positioning vertical plate 10 by bolts. Safety gratings 9 are installed on the inner side of the grating positioning vertical plate 10 by screws.

[0024] When in use, if an object such as a hand, body, or tool blocks any beam of light, the receiver will immediately identify it and output a signal to the grating controller 7, triggering the device to stop or alarm.

[0025] For example, such as Figure 1 As shown, the present invention also includes a servo motor controller 3 mounted on one end of the servo motor 2 by screws, and the output end of the servo motor controller 3 and the input end of the servo motor 2 are electrically connected by wires.

[0026] In use, the servo motor controller 3 automatically controls the rotation angle of the servo motor 2, thereby driving the grating positioning vertical plate 10 to rotate and adjust the angle of the safety grating 9.

[0027] For example, such as Figure 1 As shown, the present invention also includes mounting plates 12 welded to both sides of the bottom end of the mounting base frame 1, and mounting holes 11 are provided on the mounting plates 12.

[0028] In use, the safety light curtain protection device can be easily installed on the feed port side of the servo bending machine by using the mounting holes 11 on the mounting plate 12 and the matching bolts.
