[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-4. The present invention provides a technical solution:

[0023] In order to collect debris, prevent debris from splashing and facilitate dumping of debris during the drilling process of the drill bit, the utility model provides a sheet metal punching device as shown in the figure, including a work frame 1 with an anti-slip pad fixed on the lower surface. The device is placed on a supporting surface through the work frame 1. The anti-slip pad increases the anti-slip property between the work frame 1 and the supporting surface. A debris frame 6 is provided under the work frame 1, and the debris frame 6 can collect debris falling through the drilling hole 7.

[0024] In the utility model, a sheet metal punching assembly 4 is inserted into the moving block 3. The sheet metal punching assembly 4 includes a second motor 4.1 fixed in the moving block 3. The output shaft of the second motor 4.1 is connected to a drill bit 4.2 located below the moving block 3. One end of the drill bit 4.2 is sleeved with a second bearing. The drill bit 4.2 is connected and fixed to the moving block 3 through the second bearing. The second bearing limits the rotation position of the drill bit 4.2. A plurality of drill holes 7 located between the debris frame 6 and the drill bit 4.2 are penetrated by the work frame 1. When the second motor 4.1 is started, the drill bit 4.2 is driven to rotate through its output shaft. The rotation of the drill bit 4.2 can perform sheet metal drilling.

[0025] The upper and lower ends of the movable blocks 5.1 are connected to the upper and lower ends of the movable blocks 5.2, and the upper and lower ends of the movable blocks 5.3 are connected to the upper and lower end of the movable blocks 5.4. The upper and lower end of the movable blocks 5.5 are connected to the upper and lower end of the movable blocks 5.5 by screw threads. The collecting frame 5.5 is fixed to the inner surface of the collecting frame 5.5. The upper and lower end of the movable blocks 5.4 are connected to the upper and lower end of the movable blocks 5.1 by screw threads. The collecting frame 5.5 is fixed to the inner surface of the collecting frame 5.5. The upper and lower end of the movable blocks 5.3 are connected to the upper and lower end of the movable blocks 5.2 by the spring 5.3 sleeved around the movable blocks 5.1. The spring 5.3 is in a naturally extended state. The side surface of the collecting frame 5.5 is fixed with multiple toggle plates 5.7. The lower surface of the collecting frame 5.5 is fixed with an anti-slip pad. As shown in Figure 1, a sheet metal workpiece is placed above the workbench 1 and below the collecting frame 5.5. During the downward movement of the sheet metal punching assembly 4, the debris collection limit The overall height of the component 5 then drops until the collection frame 5.5 and the anti-slip pad on the lower surface of the collection frame 5.5 are close to the sheet metal workpiece, and then the debris collection limit component 5 continues to move downward, and the upper frame 5.4 and the movable column 5.1 move relative to the fixed plate 5.2. At this time, the spring is gradually compressed, and the anti-slip pad on the lower surface of the collection frame 5.5 is close to the sheet metal workpiece to limit the position of the sheet metal workpiece and allow the debris splashed during the drilling process of the drill bit 4.2 to be collected in the collection frame 5.5, preventing the danger caused by the splashing of debris and increasing the workload. The multiple arc-shaped limit strips 5.6 on the inner surface of the collection frame 5.5 can limit the position of the debris.

Both ends of the threaded rod 2.2 work The frames 1 are connected by bearings provided on the threaded rods 2.2. The bearings limit the working position of the threaded rods 2.2, as shown in Figures 1 and 2. When the motor 2.1 is started, the threaded rods 2.2 are driven to rotate through their output shaft. While the threaded rods 2.2 rotate, the cross plate 2.4 moves laterally around the limiting rods 2.3, thereby adjusting the lateral position of the sheet metal punching assembly 4. By controlling the extension and retraction of the electric hydraulic push rod 2.5, the sheet metal punching assembly 4 can be driven to move in the vertical direction to perform sheet metal punching work.
