[0030] See also Figure 1-6 The utility model provides a technical solution: a plate punching and shearing device that can avoid the generation of node burrs, including a base 1, a punching and shearing platform 2, a fixed rod 3, a conveying platform 4, a conveying plate 5, a fixed bolt 6, a fixed pressure plate 7, a punching cylinder 8, a punching and shearing die 9, a burr flattening die 10, a stabilizing rod 11, a limiting mechanism 12, a baffle 13, a movable column 14, a fixing groove 15, a scale code 16, an auxiliary plate 17, a limiting plate 18, a spring 19 and a support frame 20.

[0031] When using the plate punching and shearing device that can avoid node burrs, if Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the upper end of the base 1 is fixedly connected to the punching and shearing platform 2, and the limiting mechanism 12 is arranged at the right end of the punching and shearing platform 2. At the same time, the limiting mechanism 12 includes a baffle 13 telescopically connected to the right end of the punching and shearing platform 2, a movable column 14 fixedly connected to the front and rear ends of the left side of the baffle 13, a fixing groove 15 arranged at an equal interval on the upper end of the movable column 14 on the front side of the baffle 13, and a scale code 16 arranged on the upper end of the movable column 14 at the rear end of the baffle 13. By pulling the limiting plate 18 upward, the limiting plate 18 and the auxiliary plate 17 are The limit plate 18 squeezes the spring 19, causing the spring 19 to deform elastically, and the limit plate 18 is pulled out of the fixing groove 15, thereby releasing the limit between the movable column 14 and the punching and shearing table 2, and then by pulling the baffle plate 13, the baffle plate 13 drives the movable column 14 to slide between the punching and shearing table 2, thereby adjusting the distance between the baffle plate 13 and the punching and shearing die 9, and referring to the scale code 16 when pulling, the punching and shearing length of the plate can be fixed-length cut;

[0032] When adjusted to the corresponding position, the limit plate 18 is directly released. At this time, the spring 19 restores its elastic deformation, pushing the limit plate 18 and the auxiliary plate 17 to slide, so that the lower end of the limit plate 18 is engaged in the fixed groove 15 at the corresponding position, thereby facilitating the limit between the movable column 14 and the punching and shearing table 2. After the limit is completed, the punched and sheared plate is directly placed on the upper end of the conveying table 4, such as Figure 1 and Figure 2 As shown, by rotating the fixing bolt 6 threadedly connected to the upper end of the conveying plate 5, the lower end of the fixing bolt 6 is rotatably connected to the fixing pressure plate 7, and the fixing bolt 6 drives the fixing pressure plate 7 to move downward to press and fix the plate. After the fixing is completed, the conveying platform 4 is pushed to slide between the conveying platform 4 and the fixing rod 3. At this time, the conveying platform 4 drives the plate to be conveyed, and the upper end of the conveying platform 4 is flush with the upper side of the right end of the punching and shearing platform 2. When the right end of the plate contacts the baffle 13, as shown in FIG. Figure 1 and Figure 3 As shown, the punching cylinder 8 installed on the upper end of the support frame 20 is started, and the punching cylinder 8 drives the punching and shearing die 9 to move downward to punch and shear the plate, and the punching and shearing die 9 drives the stabilizing rod 11 to slide between the support frame 20, thereby improving the stability of the punching and shearing die 9 during the lifting and moving process;

[0033] In addition, the left and right ends of the punching and shearing die 9 are fixedly connected with a burr flattening die 10. The punching and shearing die 9 drives the burr flattening die 10 to move, so that the raised node burrs generated during cutting can be flattened, eliminating manual grinding and improving production efficiency. The punched and sheared plates do not need to be polished again to avoid the risk of scratches, the overall quality of the parts products is improved, and the cost is greatly saved. After the punching and shearing is completed, the plate at the right end is removed, and then the conveyor table 4 continues to be pushed to the right to drive the plate to be conveyed, thereby facilitating the cyclic punching and shearing of the plate.
