DETAILED DESCRIPTION
[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.
[0029] Embodiment: A sheet metal processing device, such as Figure 1-Figure 4 As shown, it includes a mounting frame 1, a placement bracket 2, a punching machine 3 and a discharge frame 4, the punching machine 3 is connected to the mounting frame 1, the placement bracket 2 and the discharge frame 4 are horizontally arranged in the middle of the mounting frame 1, and also includes an electric pump 5, a push plate 6, a telescopic rod 10 and a grinding roller 14, the grinding roller 14 is rotatably set on the discharge frame 4, an axial grinding groove is opened on the outside of the grinding roller 14, the placement bracket 2 is a U-shaped frame with a depression in the middle, the electric pump 5 is fixed to the middle of the placement bracket 2 by bolts, the output end of the electric pump 5 is connected to the horizontal telescopic rod 10, the push plate 6 is connected to the telescopic rod 10 by a key, the upper end of the push plate 6 is higher than the upper end surface of the placement bracket 2, after the sheet metal parts located on the upper end surface of the placement bracket 2 are processed, the electric pump 5 can be turned on to push the sheet metal parts to the grinding roller 14 of the discharge frame 4 through the push plate 6.
[0030] like Figure 4 and Figure 5 As shown, it also includes a partition 7, a baffle 8, a wedge block 801 and a first return spring 9. The partition 7 is hollow and fixed to the mounting frame 1, specifically located between the placement bracket 2 and the discharge frame 4. The baffle 8 is slidably connected in the partition 7. The first return spring 9 is connected between the baffle 8 and the partition 7. A through hole is opened in the middle of the baffle 8, and the wedge block 801 is arranged in the through hole. The inclined side of the wedge block 801 is close to the electric pump 5. The telescopic rod 10 can pass through the through hole and frictionally contact the wedge block 801.
[0031] When the upper end of the partition 7 is flush with the placement bracket 2 and the telescopic rod 10 is not in contact with the wedge block 801, the first return spring 9 is in a normal state. At this time, the upper end of the baffle 8 is higher than the partition 7. The baffle 8 can not only block and limit the sheet metal on the placement bracket 2 to prevent the sheet metal from shifting, but also block the metal debris generated when the punching machine 3 processes the sheet metal to prevent the metal debris from splashing into the discharge frame 4. When the electric pump 5 is turned on to push the processed sheet metal to the discharge frame 4, the telescopic rod 10 can penetrate into the baffle 8 and contact the wedge block 801. The end of the telescopic rod 10 contacts the inclined surface of the wedge block 801 to push it downward, that is, push the baffle 8 to move downward until the upper end is lower than the partition 7. At this time, the sheet metal can be smoothly pushed into the discharge frame 4, and the electric pump 5 is controlled to drive the telescopic rod 10 to move and reset. The telescopic rod 10 is separated from the wedge block 801, and the baffle 8 moves upward again to be higher than the partition 7.
[0032] like Figure 2 and Figure 6 As shown, it also includes a servo motor 11, a conveyor belt 12, a transmission belt 13 and a transmission assembly 15. The servo motor 11 is fixed to the side of the mounting frame 1 by bolts, the conveyor belt 12 is arranged on the discharge frame 4, and a transmission belt 13 is sleeved between the output shaft of the servo motor 11 and the rotating shaft of the conveyor belt 12. The grinding roller 14 and the conveyor belt 12 are located in the same horizontal plane. The conveyor belt 12 drives the grinding roller 14 to rotate through the transmission assembly 15. The transmission assembly 15 is composed of two gears meshing with each other, one of which is connected to the rotating shaft of the conveyor belt 12 by a key, and the other gear is connected to the end of the grinding roller 14 by a key.
[0033] like Figure 6 As shown, it also includes a pressing roller 16 and a second return spring 17. The pressing roller 16 is divided into two parts: a support rod and a rotating roller. The support rod is slidably connected to the top surface of the discharge frame 4, and the second return spring 17 is sleeved on the support rod. The rotating roller is rotatably connected to the lower end of the support rod, and the rotating roller can contact the grinding roller 14.
[0034] like Figure 7As shown, it also includes a slide rail 18 and a collection frame 19. A waste opening is opened in the middle of the placement bracket 2. The slide rail 18 is set on the bottom surface of the placement bracket 2. The collection frame 19 is slidably connected to the slide rail 18. The collection frame 19 is located at the corresponding position of the waste opening.
[0035] like Figure 8 As shown, it also includes a limit plate 20 and a third return spring 21. The limit plates 20 are arranged opposite to each other, and the limit plates 20 are slidably connected to the side of the discharge frame 4. The third return spring 21 is connected between the limit plate 20 and the discharge frame 4. After the sheet metal part is pushed to the conveyor belt 12, the limit plate 20 can correct the position of the sheet metal part, so that the sheet metal part can accurately enter between the pressing roller 16 and the grinding roller 14, which plays a positive correction role in the subsequent grinding.
[0036] The working principle of the embodiment of the present invention is as follows: the sheet metal is placed on the placement bracket 2, and then the punching machine 3 is turned on to punch the sheet metal. The punching machine 3 punches the excess metal corners into the collection frame 19. After the punching process is completed, the punching machine 3 is reset, and the electric pump 5 is turned on to push the sheet metal to the conveyor belt 12 through the push plate 6. During this period, the telescopic rod 10 contacts and pushes the wedge block 801 downward, so that the baffle 8 moves downward, and the sheet metal enters the conveyor belt 12 and is transported backward. The conveyor belt 12 drives the grinding roller 14 to rotate in the opposite direction. The grinding roller 14 can grind and deburr the surface of the sheet metal, and the pressing roller 16 can contact the upper surface of the sheet metal, so that the sheet metal can fully contact with the grinding roller 14, thereby improving the effect of the grinding roller 14 on removing burrs on the sheet metal.
[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
