Description

Technical Field

[0001] The utility model relates to the field of bending machine equipment, in particular to a material blocking and positioning device for a bending machine. Background Art

[0002] The material stopper mechanism of the bending machine is an important part of the bending machine. It is mainly responsible for positioning the plate and ensuring the bending accuracy and stability. For example, the patent number is CN202539286U, which is a patent for a rear material stopper lifting mechanism of a bending machine. The lifting screw in the patent drives the lifting cylinder to move up and down through the transmission body. The height of the material stopper seat can be adjusted by rotating the hand wheel. The lifting cylinder is equivalent to the role of the guide rail, with good operating stability, ensuring the accuracy of the adjustment.

[0003] Through detailed research and analysis, it was found that the lifting mechanism in the above-mentioned cited patents is complex and diverse, including multiple components such as lifting screws, first and second tapered bearings, handwheels, nuts, bearing seats and lifting cylinders. The interaction of these components makes the overall structure complex and large, which brings challenges to operation and maintenance; more importantly, this lifting mechanism mainly relies on handwheels for control, which is not only time-consuming and labor-intensive to operate, but also inefficient and cannot meet the high-efficiency requirements of modern production. Therefore, it is necessary to improve the shortcomings and defects of the existing technology. Utility Model Content

[0026] The transmission mechanism 4 includes a tooling housing 41, a transmission shaft 1 42, a gear 1 43, a gear 2 44, and a transmission shaft 2 45. The gear 1 43 is rotatably connected to the tooling housing 41 through the transmission shaft 1 42, and the gear 2 44 is rotatably connected to the tooling housing 41 through the transmission shaft 2 45. The gear 1 43 and the gear 2 44 are meshed with each other.

The transmission shaft 2 45 is fixedly connected to the transmission rod 5 through a coupling in a direction away from the gear 2 44.

[0027] The motor 1 3 and the transmission mechanism 4 are fixedly connected to the end of the frame 2 through a support plate 20.

[0028] Embodiment 2:

[0029] The difference between this embodiment and embodiment 1 is that:

[0030] The vertical adjustment assembly 8 includes a second motor 81, a lead screw 82, and a limit rod 83. The second motor 81 is fixed to the lower side of the connecting plate 71, and the power output end of the second motor 81 is fixedly connected to the lead screw 82. The limit rod 83 is fixed to the upper side of the connecting plate 71 and two limit rods are symmetrically arranged along both sides of the lead screw 82.

[0031] The material blocking mechanism 9 includes a lifting plate 91, a material blocking member 92, and a strip plate 93. The material blocking member 92 and the strip plate 93 have the same thickness and are fixed on the same side of the lifting plate 91. The strip plate 93 is located on the upper side of the middle of the material blocking member 92. The lead screw 82 is connected to the screw sleeve fixed to the side of the lifting plate 91 through a threaded connection, and the limit rod 83 is maintained in a vertical sliding connection with the circular sleeve fixed to the side of the lifting plate 91.

[0032] The strip plate 93 is always within the sensing range of the ultrasonic distance measuring sensor 10 when it moves vertically.

[0033] The control panel 11 is electrically connected to the motor 1 3 , the vertical adjustment component 8 , and the ultrasonic distance sensor 10 , respectively.

[0034] Working principle: In the working state of the utility model, according to the different locations of the bending points required for the plate to be bent, the motor 3 can be started through the control panel 11, such as Figure 6 As shown, since the transmission shaft 1 42 on the transmission mechanism 4 is fixedly connected to the power output shaft of the motor 1 3, when the motor 1 3 is started, the gear 1 43 can be driven to rotate through the transmission shaft 1 42, and then the screw rod 6 fixedly connected to the end of the transmission shaft 1 42 through the coupling can be driven to rotate. At the same time, the gear 1 43 can also drive the gear 2 44 to rotate through the meshing between the gears, and the gear 2 44 drives another set of transmission mechanisms 4 to rotate through the transmission shaft 2 45 and the transmission rod 5 in turn. Figure 4 As shown, after the other transmission mechanism 4 is driven, it can drive another screw rod 6 to rotate synchronously, and the two screw rods 6 on the upper side of the frame 2 rotate synchronously. Since the slider 7 is connected to the screw rod 6 by a thread, the two sliders 7 on the upper side of the frame 2 can be driven to move on the linear guide rail 21 at the same speed. At the same time, the connecting plate 71 also drives the blocking mechanism 9 to move synchronously, changing the distance between the blocking mechanism 9 and the ultrasonic ranging sensor 10 on the back of the bending device 1, as shown in FIG. Figure 5 As shown, the ultrasonic ranging sensor 10 will emit high-frequency sound waves, which will be reflected back after encountering an object. By calculating the time difference between the emission and reception of the sound waves, and combining the propagation speed of the sound waves in the air, the distance between the ultrasonic ranging sensor 10 and the material stopper 92 can be determined. Since the distance between the ultrasonic ranging sensor 10 and the bending zone on the bending device 1 is a known constant value, combined with the collection and processing of the data measured by the ultrasonic ranging sensor 10 by the control panel 11, the operator can directly read the horizontal distance between the material stopper 92 and the bending zone on the bending device 1 through the display screen on the control panel 11. The ultrasonic ranging sensor 10 can adopt the model HC-SR04, but is not limited to this model;

[0035] After the horizontal position of the stopper 92 is adjusted, the operator can start the motor 2 81 on the vertical adjustment assembly 8 through the control panel 11 to drive the screw 82 to rotate, and the screw 82 drives the stopper 92 on the lifting plate 91 through the thread to perform vertical lifting and lowering adjustment to meet the bending needs of the stopper 92 for plates of different thicknesses. The vertical adjustment assembly 8 has a simple structure and is easy to operate, and can achieve efficient adjustment of the stopper 92. After completing the above-mentioned horizontal and vertical adjustments of the stopper 92, the plate can be inserted through one side of the feed end of the bending equipment 1, so that the end of the plate is against the stopper 92, and the bending point of the plate is positioned while the stopper 92 is used to stop the material. Finally, the bending equipment 1 is started to accurately bend the plate.
