[0025] In the present application, when in use, the plastic plate workpiece 4 to be processed is placed in the placing box 9 in advance and is elastically limited, and when feeding, the extrusion mechanism 5 arranged on the mounting frame 2 can extrude one of the vertically and side-by-side placed plastic plate workpieces 4 from above the blanking hole 3 and drop it to the bending processing area on the workbench 1 for feeding operation. The automatic feeding operation is convenient, saves the trouble of manual feeding in the traditional way, saves labor intensity, and in the feeding process, the falling plastic plate workpiece 4 at the blanking hole 3 is buffered and guided by the cooperation of the extrusion mechanism 5 and the buffer assembly 6, so as to avoid collision and bouncing displacement of the plastic plate workpiece 4 when it falls from a high place on the workbench 1, improve the precision of the device feeding, and further ensure the product quality of the device bending processing.

[0026] Embodiment 2:

[0027] Reference Figures 1-5The bending machine precise feeding equipment is basically same with the embodiment 1, and further comprises: the extrusion mechanism 5 comprises: the first driving part 51 arranged on the mounting frame 2, the output end of the first driving part 51 is connected with the connecting shaft 52, the end of the connecting shaft 52 is fixedly connected with the extrusion plate 53, the surface of the connecting shaft 52 is fixedly connected with the connecting rod 54, one end of the connecting rod 54 is fixedly connected with the pressing plate 55, the buffer assembly 6 comprises the air bag 61 arranged below the pressing plate 55, the air bag 61 is arranged on the inner wall of the mounting frame 2, the surface of the air bag 61 is communicated with the gas conveying pipe 62, the end of the gas conveying pipe 62 is fixedly connected with the three air nozzles 63 penetrating through the mounting frame 2, the air nozzles 63 are arranged on one of the material guiding plates 64 at equal intervals, the two material guiding plates 64 are arranged on the bottom surface of the mounting frame 2 in the shape of inverted eight characters, the surface of the connecting shaft 52 is fixedly connected with the fixed plate 7, one end of the fixed plate 7 is fixedly connected with the mounting frame 2 through the bolt, the inner wall of the mounting frame 2 is fixedly connected with the baffle 8 on one side of the blanking hole 3, the size of the blanking hole 3 is same with the plastic plate workpiece 4, the plastic plate workpiece 4 is arranged in the placing box 9, the placing box 9 is fixedly connected with the bottom inner wall of the mounting frame 2, the inner wall of the placing box 9 is slidably connected with the pushing plate 10, the side of the pushing plate 10 is provided with the handle 12, the surface of the pushing plate 10 is fixedly connected with the extrusion spring 11 on both sides of the handle 12, one end of the extrusion spring 11 is fixedly connected with the inner wall of the placing box 9, the surface of the workbench 1 is provided with the positioning groove 13 below the blanking hole 3, the first bending die 14 is arranged in the positioning groove 13, the second bending die 15 is arranged in the positioning groove 13 on one side of the first bending die 14, one side of the second bending die 15 is fixedly connected with the output end of the second driving part 16, and the second driving part 16 is arranged on the workbench 1.

[0028] In this invention, the first drive unit 51 and the second drive unit 16 can be driven by hydraulic rods and cylinders instead of other drive sources. During use, the plastic sheet workpiece 4 is placed inside the placement box 9, allowing for the centralized storage of multiple plastic sheet workpieces 4 to be processed. The compression spring 11 can compress and limit the vertically placed plastic sheet workpiece 4, and, in conjunction with the baffle 8 on the mounting frame 2, it is elastically limited above the material discharge hole 3. After one plastic sheet workpiece 4 is compressed and fed by the compression mechanism 5, the compression spring 11 can continue to limit the plastic sheet workpiece 4, enabling automatic feeding. The operation is convenient and fast. The handle 12 allows the push plate 10 to pre-place the plastic sheet workpiece 4 into the placement box 9. During loading, the first drive unit 51 is activated, causing the extrusion plate 53 to move downwards. The extrusion plate 53 extrudes one of the plastic sheet workpieces 4 below, causing it to fall out of the dropping hole 3. The falling plastic sheet workpiece 4 lands on the surface of the left guide plate 64, while its bottom contacts the other guide plate 64, thus tilting the falling plastic sheet workpiece 4 onto the guide plate 64. The extrusion plate 53 and the plastic sheet workpiece 4 are the same size. When the extrusion plate 53 moves downward, the lower pressure plate 55 on one side moves downward and compresses the air in the airbag 61. This causes the air in the airbag 61 to be transported through the air supply pipe 62 to multiple air nozzles 63 and ejected. The ejected gas can blow the plastic sheet workpiece 4, which is leaning against one of the guide plates 64, to lean against another guide plate 64. At this time, the plastic sheet workpiece 4 will automatically continue to slide down into the positioning groove 13 on the worktable 1 due to gravity. The sliding plastic sheet workpiece 4 is limited by the positioning groove 13, so that the plastic sheet workpiece 4 placed on the worktable 1 is... This design achieves precise placement and prevents the plastic sheet workpiece 4 from bouncing and shifting when it falls from a high position and hits the worktable 1 during loading, thus improving the accuracy of bending and loading. When the plastic sheet workpiece 4 falls into the positioning groove 13, it is positioned between the first bending mold 14 and the second bending mold 15. On the one hand, the first bending mold 14 limits the falling plastic sheet workpiece 4 and keeps it in a vertical position. At this time, the second drive unit 16 is activated to drive the second bending mold 15 to cooperate with the first bending mold 14 to quickly bend the falling plastic sheet workpiece 4.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
