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.

[0025] When implementing: Figure 1-4 As shown, a material guiding structure for preparing flange blanks comprises: a workbench 1, a material guiding mechanism 2 is fixedly connected to the top of the workbench 1; wherein the material guiding mechanism 2 comprises a slide frame 21 fixedly connected to the top of the workbench 1 and distributed in equal rows, the inner wall of the slide frame 21 is slidably connected to two connecting frames 22, the inner wall of the connecting frame 22 is rotatably connected to two friction wheels 23, one end of the friction wheel 23 is fixedly connected to a first servo motor 24, the surface of the first servo motor 24 is fixedly connected to the front end of the connecting frame 22, wherein the inner wall of one side of the slide frame 21 is rotatably connected to a turntable 25, the surface of the turntable 25 is fixedly connected to a gear 26, the front end of the connecting frame 22 is fixedly connected to a rack 27, the surface of the gear 26 is meshingly connected to one side of the rack 27, and a material guiding assembly 28 is arranged on the top of the workbench 1.

[0026] The top of the workbench 1 is fixedly connected to an electric push rod, the telescopic end of the electric push rod is fixedly connected to a cutting frame, the inner wall of the cutting frame is rotatably connected to a cutting knife, one end of the cutting knife is fixedly connected to a second servo motor, and the surface of the second servo motor is fixedly connected to one side of the cutting frame.

[0027] It should be noted that the electric push rod, the second servo motor, the first servo motor 24 and the friction wheel 23 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the electric push rod, the second servo motor and the first servo motor 24 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0028] When it is necessary to prepare the flange blank, the workpiece is placed on one side of the friction wheel 23, and the turntable 25 is rotated. The rotation of the turntable 25 drives the gear 26 to rotate, and the rotation of the gear 26 drives the two racks 27 to approach each other. The rack 27 moves to drive the connecting frame 22 to move, so that the connecting frame 22 moves and drives the friction wheel 23 to move, so that the two groups of friction wheels 23 are close to each other to clamp the workpiece. At this time, the first servo motor 24 is manually turned on, and the output shaft of the first servo motor 24 rotates to drive the friction wheel 23 to rotate. The rotation of the friction wheel 23 drives the workpiece to be transported to a suitable position, and the electric push rod and the second servo motor are manually turned on. The electric push rod moves downward to drive the cutting frame and the cutting knife to move downward, so that the output shaft of the second servo motor rotates to drive the cutting knife to rotate, so that it cuts the workpiece, thereby completing the preparation of the flange blank. When the flange blank does not need to be prepared, the first servo motor 24, the second servo motor and the electric push rod are manually turned off.

[0029] like Figure 3 As shown, the material guiding assembly 28 includes a telescopic cylinder 281 fixedly connected to the inner wall of the sliding frame 21, the inner wall of the telescopic cylinder 281 is slidably connected with a telescopic rod 282, one end of the telescopic rod 282 is fixedly connected to a limit block 283, the surface of the limit block 283 is rollingly connected with a ball 284, one end of the telescopic cylinder 281 is fixedly connected to a second spring 285, and the other end of the second spring 285 is fixedly connected to one end of the telescopic rod 282.

[0030] The elastic force of the second spring 285 pushes the telescopic rod 282 to move, and the movement of the telescopic rod 282 drives the limit block 283 and the ball 284 to move, so that the ball 284 abuts against the workpiece to limit the surface of the workpiece.

[0031] like Figure 3 As shown, one side of the connecting frame 22 is fixedly connected to a placement seat 288 , the bottom of the placement seat 288 is fixedly connected to a first spring 289 , and the bottom end of the first spring 289 is fixedly connected to the top of the workbench 1 .

[0032] The movement of the connecting frame 22 on one side drives the placement seat 288 to move up, so that the placement seat 288 moves up to a suitable position, and the elastic force of the first spring 289 pushes the placement seat 288 to move up, ensuring that the workpiece is placed on the placement seat 288 and the placement seat 288 can remain stable.

[0033] like Figure 3 As shown, the front end of the turntable 25 is provided with annular fixing holes 286 , and a fixing rod 287 is slidably connected to the inner wall of one of the fixing holes 286 , and the surface of the fixing rod 287 is clamped to the inner wall of one side of the sliding frame 21 .

[0034] The fixing rod 287 slides in the corresponding fixing hole 286 and is engaged in the corresponding sliding frame 21 to fix the turntable 25 so that the two sets of friction wheels 23 can stably clamp the workpiece.

The top of the workbench 1 is provided with positioning grooves distributed in equal rows, and the bottom of the positioning frame 2813 is clamped to the inner wall of one of the positioning grooves.

[0036] When it is necessary to control the length of the cut flange blank, push the stopper 2810 to move to the appropriate position on the measuring plate 2811, turn the bolt 2812, and the bolt 2812 rotates and moves downward to contact the corresponding position on the measuring plate 2811 and drives the positioning frame 2813 to move downward, so that the stopper 2810 is fixed on the workbench 1. At this time, the workpiece contacts the corresponding position of the stopper 2810, and the cutting knife cuts the workpiece to the corresponding flange blank length.

[0037] When the utility model is in use, the stopper 2810 is pushed to move to a suitable position on the measuring plate 2811, and the bolt 2812 is rotated. The bolt 2812 rotates and moves downward to contact the corresponding position on the measuring plate 2811 and drives the positioning frame 2813 to move downward, so that the stopper 2810 is fixed at the corresponding position of the workbench 1, and the workpiece is placed on the friction wheel 23 on one side, and the turntable 25 is rotated. The rotation of the turntable 25 drives the gear 26 to rotate, and the rotation of the gear 26 drives the two racks 27 to approach each other. The movement of the rack 27 drives the connecting frame 22 to move, so that the movement of the connecting frame 22 drives the friction wheel 23 to move, so that the two sets of friction wheels 23 are close to each other to clamp the workpiece. At this time, the fixed The fixed rod 287 slides in the corresponding fixing hole 286 and is engaged in the corresponding sliding frame 21 to fix the turntable 25. At this time, the first servo motor 24 is manually turned on, and the output shaft of the first servo motor 24 rotates to drive the friction wheel 23 to rotate. The rotation of the friction wheel 23 drives the workpiece to abut against the block 2810. The electric push rod and the second servo motor are manually turned on, and the electric push rod moves downward to drive the cutting frame and the cutting knife to move downward, so that the output shaft of the second servo motor rotates to drive the cutting knife to rotate, so that it cuts the workpiece, thereby completing the preparation of the flange blank. When the flange blank does not need to be prepared, the first servo motor 24, the second servo motor and the electric push rod are manually turned off.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
