[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] See also Figure 1-5 A punching machine with automatic feeding includes a body 1, a table 2 is fixed on the upper end of the body 1, an extension table 3 is fixedly connected to the outer side of the table 2, a material guide groove 4 is opened on the table 2, and the material guide groove 4 is arranged through the extension table 3, and fixed rods 5 are fixedly connected to both sides of the upper end of the extension table 3, and a cross bar 6 is slidably connected to the fixed rod 5. An auxiliary mechanism is arranged at one end of the cross bar 6 close to the inner side of the body 1, and a feeding mechanism is arranged at one end of the cross bar 6 close to the extension table 3. The feeding mechanism includes a top cylinder 15 fixed to the upper end of the extension table 3, a material baffle plate 12 is arranged at the outer end of the cross bar 6, and a support frame 13 is connected between the material baffle plates 12. A material guide piece is fixed to the output end of the top cylinder 15, and the material guide piece is matched with the lower end of the material baffle plate 12.

[0024] The specific working principle and implementation method are as follows: an extension platform 3 is arranged on the outer side of the table 2 of the body 1, and a material guide trough 4 is opened on the table 2 and the extension platform 3, and is connected to each other. The output end of the top cylinder 15 drives the material guide member to push the sheet material placed in the material baffle plate 12 and the support frame 13 to the bottom of the stamping end of the body 1, and the sheet material is stacked inside the material baffle plate 12 and the support frame 13. After the sheet material is pushed into the stamping end by the material guide member at the lower end, the sheet material falls into the material guide trough 4 by gravity, and then the next push is carried out; the advantage of such a design is that the material guide member is driven to reciprocate by the top cylinder 15, and the sheet material is continuously pushed into the stamping place during the reciprocating motion, and the continuous pushing can drive the sheet material to be unloaded, so that small sheets can be continuously loaded, thereby increasing the stamping efficiency of the sheets, and the probability of safety accidents can be reduced to zero through automatic loading.

[0025] like Figure 4As shown, the auxiliary mechanism includes a connecting frame 7 fixed on the inner end of the cross bar 6, the lower end of the connecting frame 7 is fixedly connected with a pressure rod 8, the lower end of the pressure rod 8 is fixedly connected with a roller 9, and the roller 9 is matched with the upper end of the sheet; through the connection of the connecting frame 7, the lower end of the connecting frame 7 is fixed with a pressure rod 8, and the lower end of the pressure rod 8 is fixed with a roller 9, and the number of rollers 9 is multiple, so that the sheet can be prevented from deviating to the upper end during the sheet conveying process, thereby reducing the error rate of sheet conveying.

[0026] like Figure 5 As shown, the material guide member includes a guide plate 17, which is circular in design. An extrusion ring 16 is fixedly connected to the outer side of the upper end of the guide plate 17. The extrusion ring 16 is elliptical in design. The circular guide plate 17 can reduce the friction between the guide plate 17 and the material guide groove 4, and the extrusion ring 16 is compressed as the guide plate 17 moves. The extrusion ring 16 hits the lower end of the baffle plate 12, causing the internal sheet material to vibrate slightly, thereby achieving a more stable material feeding effect and avoiding jamming of the internal sheet material.

[0027] like Figure 5 As shown, a spring 10 is sleeved on the fixing rod 5, and a fixing button 11 is threadedly connected to the fixing rod 5 located on the cross bar 6; the upper and lower positions of the cross bar 6 can be fine-tuned according to the thickness of the sheet material, and the spring 10 can reduce the loosening of the cross bar 6 when it is subjected to stamping vibration.

[0028] like Figure 5 As shown, a layering strip 14 is fixedly connected to the inner side of the lower end of the outer baffle plate 12, and the end of the layering strip 14 is tilted downward; when the lowermost sheet enters the guide groove 4, the upper sheet is lifted up on one side by the layering strip 14, and the vibration of the extrusion ring 16 is used to assist in unloading, thereby achieving the sheet unloading effect.

[0029] like Figure 4 As shown, the contact surface between the roller 9 and the sheet material is a section setting; the section setting is to reduce the friction of the roller 9 on the sheet material, and the roller 9 only limits the position of the sheet material to achieve the effect of stabilizing the sheet material transportation.

[0030] like Figure 3 As shown, both sides of the stamping part on the table top 2 are provided with clearance grooves 18, symmetrical extrusion springs 19 are fixedly connected in the clearance grooves 18, and the outer ends of the extrusion springs 19 are fixedly connected with stoppers 20, and the stoppers 20 are matched with the sheet material; after the sheet material is pushed into the stamping part, it can be positioned by the limiting stopper 20, and when it is pushed out again, the extrusion of the extrusion springs 19 can achieve a contraction effect.
