Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing machine tools, in particular to a feeding structure of a sheet metal numerical control processing machine tool. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching, cutting, compounding, folding, and forming. Its most notable feature is that the thickness of the same part is consistent. Sheet metal has the characteristics of light weight, high strength and low cost. Therefore, it has been widely used in electronic appliances, communications, medical equipment and other fields. CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system that can automatically process parts according to the shape and size required by the drawing.

[0003] After the sheet metal is processed by the CNC machine, it needs to be manually carried to remove the processed sheet metal material. If the sheet metal material is large in area, it is not easy to remove it from the CNC machine manually, and it is easy to scratch the hands of the staff. In addition, during the sheet metal processing, the sheet metal lacks fixed limits, and the sheet metal plate may be offset, which may cause the sheet metal processing and cutting to be relatively inaccurate. Therefore, in response to the above problems, we provide a new feeding structure for sheet metal CNC processing machines. Utility Model Content

[0024] 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.

[0026] In a specific implementation, by starting the servo motor 14, the tooth block 11 connected by the connecting shaft is driven to rotate. When the tooth block 11 rotates, the ring toothed belt 12 cooperates with the tooth block 11 to drive the other tooth blocks 11 to rotate, so that when the tooth block 11 rotates, the feeding column wheel 10 can be driven to rotate in the empty slot 8 in the receiving plate 7 through the receiving rod 9, so that the two receiving plates 7 are pushed by the cylinder 6, and the sheet metal plate clamped and limited by the feeding column wheel 10 in the empty slot 8 of the receiving plate 7 can be fed to one side, so that the sheet metal material after processing is pushed out of the workbench 1.

The arc-shaped bent plate 17 can better facilitate the insertion of sheet metal, and the overall design has a certain practical effect.

[0028] like Figure 2 , 3As shown, in the present embodiment, a collecting trough 18 is provided in the middle of the top surface of the workbench 1, and a plurality of fixed round rods 19 are fixedly connected equidistantly above the inner wall of the collecting trough 18, screw rods 20 are rotatably connected inside the two sides of the collecting trough 18, and movable blocks 21 are threadedly connected to the outer walls of the screw rods 20, and push plates 22 are fixedly connected to the adjacent ends of the two screw rods 20, and the rear ends of the two screw rods 20 pass through the outer wall of the workbench 1 and are fixedly connected to transmission wheels 23, and the two transmission wheels 23 are connected by a transmission belt, and an L-shaped bracket 24 is fixedly connected to the rear outer wall of the workbench 1, and a servo motor 25 is fixedly connected to the top end of the L-shaped bracket 24, and the driving end of the servo motor 25 is fixedly connected to the middle of the adjacent transmission wheel 23 through a connecting shaft.
