Description

Technical Field

[0001] The utility model relates to the technical field of stamping waste cleaning, in particular to an automatic stamping waste removal device. Background Art

[0002] Stamping is a forming process that applies external forces to plates, strips, pipes, profiles, etc. by a press and a die, causing plastic deformation or separation to obtain workpieces (stamped parts) with the required shapes and sizes. Stamping and forging belong to plastic processing (or pressure processing) together, collectively called forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips.

[0003] During the stamping process, a large amount of waste will inevitably be generated, such as scraps and debris. If these wastes are not cleaned up in time, they will not only occupy the working space and affect production efficiency, but may also hinder the normal operation of the stamping machine, and even cause equipment failures or safety accidents. The stamping waste removal devices in the prior art have poor cleaning effects and can only clean the scraps around the die, and it is not convenient to clean the debris on the die. However, the debris generated by stamping is easy to adhere to the die, and after long-term accumulation, it is easy to affect the finished products. Summary of the Utility Model

[0024] Embodiment 1

[0025] Please refer to Figures 1-5 As shown, an automatic waste removal device for a stamping machine includes an installation frame 1. Four groups of fixed columns 101 are fixedly connected to the lower end of the installation frame 1. A flipping mechanism 2 is installed at the upper end of the installation frame 1. The flipping mechanism 2 includes a fixed frame 201. The fixed frame 201 is fixedly connected to the upper end of the installation frame 1. A flipping plate 202 is arranged inside the fixed frame 201. A stamping die 203 is fixedly connected to the upper end of the flipping plate 202. Rotating shafts 204 are fixedly connected to both the left and right sides of the flipping plate 202. The rotating shafts 204 are rotatably connected to the inside of the fixed frame 201 through bearings. A cleaning mechanism 3 is installed inside the installation frame 1. The cleaning mechanism 3 includes an installation plate 306. The installation plate 306 is slidably connected to the inside of the installation frame 1. A cleaning brush 310 is slidably connected to the inside of the installation plate 306.

[0026] In this solution, the flipping plate 202 can drive the stamping die 203 to rotate 180° through the rotating shaft 204, so that the stamping die 203 flips downward. During the flipping process, due to the inclination of the stamping die 203, the corner materials around the stamping die 203 can be cleaned and collected by an external collection mechanism;

[0027] Further, the mounting plate 306 can slide inside the mounting frame 1, thereby driving the cleaning brush 310 to clean the surface of the stamping die 203. The cleaning brush 310 can slide inside the mounting plate 306, so that the cleaning brush 310 always abuts against the surface of the stamping die 203, increasing the acting force of the cleaning brush 310 on the stamping die 203, thereby enhancing the cleaning effect of the cleaning brush 310 on debris. By turning the stamping die 203 downward, when cleaning the stamping die 203, the debris on the stamping die 203 can directly fall off, preventing debris residue.

[0028] Embodiment 2

[0029] Please refer to Figure 2 As shown in the figure, an electric push rod 207 is fixedly installed on the outer side of the fixed frame 201. The output end of the electric push rod 207 is fixedly connected to a toothed plate 206. One of the rotating shafts 204 extends to the outside of the fixed frame 201 and is fixedly connected to a rotating gear 205 that meshes with the toothed plate 206.

[0030] In this solution, the electric push rod 207 is electrically connected to an external power source. The electric push rod 207 can push the toothed plate 206 to move, thereby driving the rotating gear 205 to rotate the rotating shaft 204, and then driving the turning plate 202 to rotate.

[0031] Embodiment 3

[0032] Please refer to Figures 3-5 As shown in the figure, sliding blocks 305 are fixedly connected to both the left and right ends of the mounting plate 306. A sliding groove 102 is formed inside the mounting frame 1, and the sliding blocks 305 are slidably connected to the inside of the sliding groove 102.

[0033] The cleaning mechanism 3 further includes two groups of screw rods 303. The screw rods 303 are rotatably connected to the inside of the sliding groove 102 through bearings. The sliding blocks 305 are threadedly connected to the screw rods 303. One end of the screw rod 303 extends to the outside of the mounting frame l and is fixedly connected to a second bevel gear 304.

[0034] The cleaning mechanism 3 further includes a bidirectional motor 301. The bidirectional motor 301 is fixedly installed on the outside of the mounting frame 1. The output ends on both sides of the bidirectional motor 301 are fixedly connected to first bevel gears 302 that mesh with the second bevel gears 304.

[0035] A collection groove 307 is arranged at the lower end of the mounting plate 306. Guide rods 308 are fixedly connected to both the left and right ends of the collection groove 307. Guide rails 309 are fixedly connected to both the left and right ends of the mounting plate 306. The guide rods 308 are slidably connected to the guide rails 309.

[0036] A number of cleaning springs 311 are fixedly connected inside the mounting plate 306. One end of the cleaning spring 311 away from the mounting plate 306 is fixedly connected to the cleaning brush 310.

[0037] In this solution, the bidirectional motor 301 is electrically connected to an external power supply. The bidirectional motor 301 can drive the second bevel gear 304 to rotate through the first bevel gear 302, and then drive the screw 303 to rotate, so that the slider 305 can slide inside the chute 102, thereby driving the mounting plate 306 to move;

[0038] Furthermore, the debris removed can be collected through the collection groove 307. The collection groove 307 can slide inside the guide rail 309 through the guide rod 308. After the guide rod 308 and the guide rail 309 are derailed by sliding the collection groove 307, the collection groove 307 can be removed, thereby facilitating the cleaning of the debris in the collection groove 307;

[0039] Furthermore, the cleaning spring 311 can push the cleaning brush 31o to abut against the stamping die 203, thereby increasing the acting force of the cleaning brush 310 on the stamping die 203.

[0040] The working principle and usage process of the present utility model are as follows: First, during cleaning, the electric push rod 207 is started, and the toothed plate 206 is pushed to move, thereby driving the rotating gear 205 to rotate the rotating shaft 204, and then driving the turning plate 202 to perform a 180° turn, so that the stamping die 203 turns downward. After that, the bidirectional motor 301 is started, and the second bevel gear 304 is driven to rotate through the first bevel gear 302, and then the screw 303 is driven to rotate, so that the slider 305 can slide inside the chute 102, thereby driving the mounting plate 306 to move, and at the same time driving the cleaning brush 310 to clean the surface of the stamping die 203. The debris is cleaned by the cleaning brush 310 and falls into the collection groove 307 for collection. After that, the collection groove 307 is slid to derail the guide rod 308 from the guide rail 309, and the collection groove 307 is removed, thereby facilitating the cleaning of the debris in the collection groove 307.
