DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 - Figure 4 shown, a raw material transfer structure for a punching machine includes a support 1, a material transfer mechanism 2 and a loading mechanism 3. The material transfer mechanism 2 is slidably connected to the upper surface of the support 1, and the loading mechanism is fixedly connected to the outer surface of the support 1. The loading mechanism includes a fixed frame 308 fixedly connected to the outer surface of the support 1. A plurality of limit frames 301 are attached to the upper surface of the fixed frame 308. A second threaded rod 311 is rotatably connected to the inner wall of the fixed frame 308. A sliding block 310 is threadedly connected to the outer surface of the second threaded rod 311. A pushing plate 306 is fixedly connected to the outer surface of the sliding block 310. The outer surface of the pushing plate 306 is slidably connected to the upper surface of the support 1.

[0025] In order to facilitate continuous feeding of the material plate, a fixing bolt 302 is bolted to the outer surface of the limit frame 301, and the outer surface of the fixing bolt 302 is bolted to the upper surface of the fixing frame 308. By rotating the fixing bolt 302, the fixing bolt 302 is separated from the fixing frame 308, thereby facilitating the adjustment of the position of the limit frame 301 on the upper surface of the fixing frame 308 and facilitating the feeding of materials of different sizes. A groove 303 is formed on the outer surface of the limit frame 301, and a limit plate 305 is slidably connected to the outer surface of the groove 303. A plurality of threaded holes are formed on the outer surfaces of the groove 303 and the limit plate 305, and a limit bolt 304 is threadedly connected to the outer surface of the limit plate 305. The other end of the limit bolt 304 is threadedly connected to the threaded hole formed on the outer surface of the groove 303. By rotating the limit bolt 304, the limit bolt 304 is separated from the outer surface of the groove 303, facilitating the adjustment of the distance between the lower surface of the limit plate 305 and the upper surface of the fixing frame 308, and thus facilitating the limitation of materials of different thicknesses. A second reduction motor 307 is fixedly connected to the outer surface of the fixing frame 308. The output shaft of the second reduction motor 307 passes through the inner wall of the fixing frame 308 and is fixedly connected to the outer surface of the second threaded rod 311. The outer surface of the second reduction motor 307 is electrically connected to a control panel 309 through a wire. The outer surface of the control panel 309 is fixedly connected to the outer surface of the support 1. By starting the fixing frame 308, the output shaft of the fixing frame 308 drives the second threaded rod 311 to rotate, and the rotation of the second threaded rod 311 drives the sliding block 310 to slowly slide towards the outer surface of the material transfer plate 203, thereby avoiding the displacement of the material plate due to inertia caused by too fast speed.

[0026] It is worth mentioning that the position of the limit frame 301 on the upper surface of the fixing frame 308 is adjusted according to the size of the material plate. The limit frame 301 is fixed on the upper surface of the fixing frame 308 using the fixing bolt 302. Then, the limit bolt 304 is rotated to facilitate the limitation of material plates of different thicknesses. Then, the control panel 309 is started, so that the second reduction motor 307 drives the second threaded rod 311 to rotate. The rotation of the second threaded rod 311 drives the sliding block 310 and the pushing plate 306 to slide on the outer surface of the fixing frame 308. The pushing plate 306 drives the material plate to slowly move towards the outer surface of the material transfer plate 203, thereby avoiding the displacement of the material plate due to inertia caused by too fast speed, enabling the material to move to the upper surface of the material transfer plate 203, and facilitating continuous feeding of the material plate.

[0027] In order to improve the loading and unloading efficiency of the material plate, the material transfer mechanism 2 includes two groups of material transfer plates 203 slidably connected to the upper surface of the support 1. A connecting block 204 is fixedly connected to the lower surface of the material transfer plate 203. The material transfer mechanism 2 further includes a first reduction motor 201 fixedly connected to the outer surface of the support 1. The output shaft of the first reduction motor 201 passes through the inner wall of the support 1 and is fixedly connected to a first threaded rod 202. The outer surface of the first threaded rod 202 is threadedly connected to the outer surface of the connecting block 204. By starting the first reduction motor 201, the output shaft of the first reduction motor 201 drives the first threaded rod 202 to rotate. The rotation of the first threaded rod 202 drives the connecting block 204 to slide along the direction of the first threaded rod 202. The sliding of the connecting block 204 drives the two groups of material transfer plates 203 to slide synchronously, thereby facilitating the loading and unloading of the punching machine. A chute 205 is provided on the upper surface of the support 1. The outer surface of the chute 205 is slidably connected to the outer surface of the connecting block 204. The chute 205 facilitates the connecting block 204 to drive the material transfer plate 203 to slide on the upper surface of the support 1.

[0028] It is worth mentioning that by starting the first reduction motor 201, the material transfer plate 203 is moved to the lower part of the punching machine, facilitating the stamping of the material plate on the upper surface of the material transfer plate 203. After stamping is completed, the connecting block 204 drives the material transfer plate 203 to slide towards the direction of the other fixed frame 308, thereby facilitating the unloading of the stamped material plate. After unloading is completed, pressing the control panel 309 facilitates moving the material plate back to the upper surface of the material transfer plate 203, thereby facilitating the loading and unloading of the material plate on both sides of the punching machine. On the one hand, it improves the loading and unloading efficiency of the material plate, and on the other hand, it facilitates preventing the situation where the user is injured by the punching machine.

[0029] Working principle: Set the punching machine between two groups of fixed frames 308, then move the material transfer plate 203 below the punching machine, and then adjust the position of the limit frame 301 on the upper surface of the fixed frame 308 according to the size of the material plate. Use the fixing bolt 302 to fix the limit frame 301 on the upper surface of the fixed frame 308. Then rotate the limit bolt 304 to separate the limit bolt 304 from the groove 303, which is convenient for adjusting the distance between the limit plate 305 and the fixed frame 308, and is convenient for limiting material plates of different thicknesses. Then, when the material transfer plate 203 fits against the outer surface of the fixed frame 308, start the control panel 309 so that the second reduction motor 307 drives the second threaded rod 311 to rotate. The rotation of the second threaded rod 311 drives the sliding block 310 and the material pushing plate 306 to slide on the outer surface of the fixed frame 308. The material pushing plate 306 drives the material plate to slowly move towards the outer surface of the material transfer plate 203, thereby avoiding the situation where the material plate is displaced due to inertia caused by too fast a speed, and making the material move to the upper surface of the material transfer plate 203. Then start the first reduction motor 201. The output shaft of the first reduction motor 201 drives the first threaded rod 202 to rotate. The rotation of the first threaded rod 202 drives the connecting block 204 to slide along the direction of the first threaded rod 202. The sliding of the connecting block 204 drives the two groups of material transfer plates 203 to slide synchronously, thereby making the material transfer plate 203 move below the punching machine, which is convenient for punching the material plate on the upper surface of the material transfer plate 203. After punching is completed, the connecting block 204 drives the material transfer plate 203 to slide towards the direction of the other fixed frame 308, which is convenient for discharging the punched material plate. After discharging is completed, press the control panel 309 to move the material plate to the upper surface of the material transfer plate 203, which is convenient for loading and unloading the material plate on both sides of the punching machine. On the one hand, the loading and unloading efficiency of the material plate is improved, and on the other hand, it is convenient to prevent the operator from being injured by the punching machine.
