[0015] 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.

[0016] like Figure 1 and Figure 2 As shown, an automated punching machine includes a workbench 1, a punching hole is provided in the center of the workbench, a punching head structure 2 is provided above the workbench, and the punching head structure can be connected to an external machine through a three-axis movable structure. A limiting structure 3 for positioning a plate is provided on the workbench, and specifically, the limiting structure includes a fixed plate 5, and an intermediate plate 6 perpendicular to the fixed plate is provided in the middle of the fixed plate, and the intermediate plate and the fixed plate can be integrally formed. Side plates 7 are slidably connected to both ends of the fixed plate, and the side plates and the intermediate plates cooperate to limit the plate. The fixed plate is slidably connected to the workbench, and a conveying and unloading structure 4 is provided on both sides of the workbench, and the conveying and unloading structures are arranged on the external frame. The conveying and unloading structure is used to unload the plate between the side plate and the intermediate plate. The intermediate plate is also slidably connected to a pressing plate 8, and the pressing plate is used to press the plate to one side of the fixed plate. A push plate 9 is slidably connected to one end of the side plate close to the fixed plate.

[0017] Furthermore, the middle plate includes two sections of split plates, which are plugged and connected, one end of which is provided with a groove, and the other end of which is provided with a connecting portion inserted into the groove. The groove wall of the groove is provided with a plurality of evenly arranged fixing screw holes upward, and the fixing screw holes are provided with fixing bolts, which abut against the connecting portion. The length of the middle plate is adjustable, and it can adapt to plates of different sizes and clamp them in a limited position.

[0018] The pressing plate comprises a second fixing plate, and a protruding pressing portion is arranged on the second fixing plate toward one side of the fixing plate.

[0019] The front end of the workbench is also provided with a material unloading slope. The push plate is pushed forward to push the plate into the material unloading slope for unloading.

[0020] The working principle of the utility model is as follows: the conveying and unloading structure on one side unloads a plate to between the side plate and the middle plate, the pressing plate presses against the plate so that the plate contacts the push plate and then resets, and then the side plate cooperates with the middle plate to clamp it and move it to the bottom of the punching head for punching, and the other side plate and the middle plate receive the unloaded plate from the conveying and unloading structure on the other side, and after the punching is completed, the limiting structure moves, and the plate on the other side is located under the punching head. After the punching is completed, the push plate pushes the plate to the lower material slope for unloading, and then receives a new plate to be processed. On the whole, the two groups of unloading plates are symmetrical, and loading and unloading and punching are carried out simultaneously, which also improves production efficiency.
