[0002] Hardware manufacturing refers to the processing industry that uses metal as the main raw material, involving multiple links such as cutting, forming, processing and assembly of metal materials. In the hardware manufacturing process, the bending device is a commonly used equipment used to bend metal plates, strips and other materials into parts of the required shape and size through pressure. In the process of hardware pipe manufacturing, the bending machine is an important equipment to achieve the shape and size accuracy of the pipe. When using the bending machine to process the hardware pipe, workers usually need to manually support the pipe to ensure that the pipe can maintain the correct position and posture when it is subjected to the bending force. However, there is a certain uncertainty in the manual support method, because the movement of the worker's hand when supporting the pipe may cause the position of the pipe to shift, thereby affecting the processing accuracy.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The bending device for hardware manufacturing is provided with a fixed shaft, a swivel, a fixed plate, a long groove, a driving rod, an elastic rod and a limiting groove. When the hardware tube needs to be processed, the hardware tube is placed in a movable pulley and then overlapped on the telescopic rod.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a bending device for hardware manufacturing, comprising a bottom plate 1, a frame 2 is connected to the bottom plate 1, two fixed pulleys 3 are connected in the frame 2, a hydraulic cylinder 4 is connected in the frame 2, a movable pulley 5 is connected to the hydraulic cylinder 4, a hardware tube 6 is overlapped on the movable pulley 5, a telescopic rod 7 is connected to the bottom plate 1, a fixing device 8 is connected to the telescopic rod 7, an adjusting device 9 is provided on the fixing device 8, and the adjusting device 9 comprises a connecting block 91, the connecting block 91 is connected to the front of the telescopic rod 7, a slide plate 92 is slidably connected in the connecting block 91, a plurality of fixing grooves 93 are provided in the shrinking slide plate 92, a fixing rod 94 is slidably connected in the connecting block 91, and by setting the fixing groove 93 and the fixing rod 94, the fixing groove 93 cooperates with the fixing rod 94, so that the fixing rod 94 limits the fixing groove 93, and avoids the shaking of the fixing groove 93 during the processing;

[0022] The fixing rod 94 is clamped in a fixing groove 93, a limiting groove 95 is provided on one side of the slide plate 92, and the elastic rod 86 is clamped in the limiting groove 95;

[0023] The hydraulic cylinder 4 is externally connected with a driving rod 10, and the driving rod 10 is externally slidably connected with a slider 11, and the slider 11 is clamped in the telescopic rod 7. By setting the slider 11 and the telescopic rod 7, the slider 11 cooperates with the telescopic rod 7, so that when the slider 11 slides out of the telescopic rod 7, the telescopic rod 7 loses its limit at this time, and the telescopic rod 7 will shrink rapidly, avoiding the influence of the telescopic rod 7 on the bending process. By setting the driving rod 10 and the telescopic rod 7, the driving rod 10 cooperates with the telescopic rod 7, so that when the driving rod 10 is driven by the hydraulic cylinder 4, the telescopic rod 7 can be driven to move synchronously;

[0024] The fixing device 8 includes a fixing block 81, which is connected to the back of the telescopic rod 7, a fixing plate 84 overlapped on the outside of the hardware tube 6, a fixing shaft 82 is connected through the fixing block 81, two rotating rings 83 are arranged on the outer surface of the fixing shaft 82, and the same fixing plate 84 is connected to the two rotating rings 83, a long groove 85 is opened in the fixing plate 84, and an elastic rod 86 is connected in the long groove 85. By setting the elastic rod 86 and the limiting groove 95, the elastic rod 86 cooperates with the limiting groove 95, so that the elastic rod 86 lowers the limiting groove 95, thereby avoiding the limiting groove 95 from shaking during the processing;

[0025] The driving rod 10 is connected to the outside of the telescopic rod 7 .

[0026] The working principle of the utility model is:

[0027] When the hardware tube 6 needs to be processed, the hardware tube 6 is placed in the moving pulley 5 and then overlapped on the telescopic rod 7. At this time, the fixed plate 84 is rotated, and the fixed plate 84 rotates outside the fixed shaft 82 through the swivel 83. Then, when the elastic rod 86 is inserted into the limit groove 95, the hardware tube 6 is fixed. When the hydraulic cylinder 4 drives the hardware tube 6 to move, the driving rod 10 is driven to move synchronously. Then, the driving rod 10 drives the telescopic rod 7 to extend. When the hardware tube 6 overlaps the fixed pulley 3, the elastic rod 86 is pulled. Move it away from the limiting groove 95, and then pull the slider 11 to slide out of the telescopic rod 7. At this time, the slider 11 loses its limit on the telescopic rod 7, and the telescopic rod 7 will shrink rapidly. When it is necessary to fix the hardware tubes 6 of different sizes, the fixing rod 94 can be removed at this time, and then the slide plate 92 is pulled to slide in the connecting block 91. After sliding to a suitable position, the fixing rod 94 is inserted into the corresponding fixing groove 93. At this time, the position of the limiting groove 95 is adjusted, and the fixation of the hardware tube 6 and the application of hardware tubes 6 of different sizes are completed.
