[0002] As we all know, a bending machine is a machine that can bend thin plates. However, if the leveling error of the bending machine slider is too large after the welding process, or the bending machine slider is deformed front and back during the subsequent use, the angle of the folded product will be unqualified. During debugging, the staff needs to adjust the straightness of the slider based on experience.

[0021] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front",
[0023] The directions or positional relationships indicated by “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0024] Embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, a bending machine slider straightness detection device includes a bending machine body assembled by a bending machine slider 1, a frame and a touch display screen, a linear guide rail 3 is arranged on the rear plate surface of the bending machine slider 1, a detection device is slidably arranged on the linear guide rail 3, and corresponding receiving devices 2 for receiving detection device signals are symmetrically arranged on both sides of the bending machine slider 1, and the detection device can detect the straightness of the slider.
[0025] The linear guide 3 is fixedly mounted on the plate surface of the bending machine slider 1 by means of hexagon socket bolts. The linear guide 3 is installed parallel to the bending machine slider 1. The receiving device 2 is fixedly mounted on both sides of the bending machine slider 1 by means of galvanized bolts and can receive the signal of the detection device.
[0026] Through the setting of the above scheme, the detection device can slide on the linear guide rail. The position deviation of the slider straightness can be detected by moving the detection device, and through the feedback of the receiving device, this receiving device is electrically connected to the control system of the bending machine. Through the data processing module and data output module of the control system, the deviation of the bending machine slider relative to the ideal straightness can be obtained. This device is mainly used to detect the front and rear curvature of the bending machine slider.
[0027] The detection device comprises a sliding block, a bracket 4 and a detector. The sliding block is slidably arranged on the linear guide rail 3 , the sliding block is provided with a bracket 4 , and the bracket 4 is provided with a detector.
[0028] The bracket 4 is L-shaped, the bracket 4 opens outward, and the detector is fixedly mounted on the upper surface of the long side of the bracket 4 .
[0029] The bracket 4 is fixed to the sliding block by means of hexagon socket bolts, and the detector is fixed to the sliding block by means of galvanized bolts. The use of galvanized bolts is more durable.
[0030] This makes it convenient for the detector to move along with the moving support 4.
[0031] The detector is a sensor 5, and the signal emitted by the sensor is a laser signal.
[0032] The receiving device is a receiver 2 for receiving laser signals.
[0033] A detection line is formed between the receiver 2 and the sensor 5. Therefore, when the actual straightness and ideal straightness of the bending machine slider exceed the tolerance range, the detection line will change accordingly.
[0034] The detection device and the receiving device are electrically connected to the touch display screen.
[0035] The touch screen is electrically connected to the bending machine control system. When the signal in the detection device is transmitted to the receiving device, the electrical signal is converted into a digital signal through the system information processing module, and then output to the touch screen through the system output module. The touch screen will display the specific deformation value, which is convenient for the operator to debug.
[0036] In this embodiment, when the sensor 5 detects that the actual straightness of the bending machine slider deviates from the ideal straightness, a certain offset will also occur between the laser signal emitted by the sensor 5 and the laser receivers 2 at both ends of the bending machine slider. This electrical signal is converted into a digital signal by the system processing module, output by the system output module, and transmitted to the touch screen of the bending machine, so that the deformation position and deformation amount can be directly read.
[0037] The working principle of the utility model is as follows: Figure 4 As shown, when it is found that the bent product exceeds the allowable tolerance range or when maintenance is performed at intervals, the sensor 5 is moved along the linear guide 3. When it moves to the deformation area, if the bending machine slider 1 is deformed, because the linear guide 3 is fixed on the bending machine slider 1, it will also deform, and the sensor 5 moves with the linear guide 3. The horizontal position of the sensor 5 changes, and the laser line projected on the receiver will also change, and a certain offset will be obtained in the horizontal direction. Of course, this offset is not very large, about 0.8mm. After receiving this data, the receiver converts and outputs the signal through the data processing module and the data output module of the control system. This signal will eventually be displayed on the touch screen, and the operator can know the deformation amount and deformation position of the slider by touching the touch screen.
[0038] Finally, the straightness of the slider of the bending machine can be adjusted by an adjustment device, for example, a deflection compensation shaft can be installed on the slider of the bending machine, and the straightness of the slider can be adjusted by pushing it forward or pulling it back with a screw to ensure that the straightness of the slider is within the allowable tolerance range so as to fold a workpiece that meets the bending angle.
[0039] The utility model adopts a simple mechanical structure and a high-precision sensor, so that when the bending machine slider is elastically deformed and the straightness exceeds the tolerance range, affecting the product quality, the deformation position can be found in time and accurately. The time of manual inspection is reduced, and the technical level requirements for the debugging personnel are also reduced, so as to avoid the debugging personnel blindly debugging due to lack of experience and affecting the straightness accuracy of the slider. When the slider is elastically deformed, the detector can be moved slowly, and the slider straightness data sensed by the detector can be reflected in time on the touch screen, and the deformation position and deformation amount are clearly marked. The debugging personnel find the corresponding position and use the adjustment device to adjust it so that the straightness of the bending machine slider can be restored to the allowable tolerance range. The service life of the bending machine slider is extended, the accuracy and precision of the bending machine slider during debugging and use are guaranteed, and the equipment utilization rate is effectively improved.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
