[0024] In the embodiment, as shown in Figures 1 to 6 A through-hole punching and deburring device for an aluminum alloy light box casting includes a frame 10. The top surface of the top plate of the frame 10 is fixedly provided with an upper support frame 20. A central blanking through groove 11 is formed in the middle of the top plate of the frame 10. The top surface of the top plate of the frame 10 is fixedly connected by bolts or directly welded with a horizontal fixed plate 12. An upper through groove 121 is formed in the middle of the horizontal fixed plate 12. The upper through groove 121 communicates with and aligns with the central blanking through groove 11. The left, right, front, and rear parts of the top surface of the horizontal fixed plate 12 are fixedly connected by bolts with side limit blocks 13. The aluminum alloy light box 100 to be processed is placed on the top surface of the horizontal fixed plate 12. The side walls of the side vertical plates of the four side limit blocks 13 are closely attached to the outer side walls of the corresponding side plates of the aluminum alloy light box 100;
[0025] The side limit block 13 is an L-shaped block. Two waist-shaped through holes 131 are formed in the middle of its bottom plate. The screw part of the bolt is inserted into the corresponding waist-shaped through hole 131. Its bottom end extends out of the bottom end of the corresponding waist-shaped through hole 131 and is screwed into the corresponding vertical screw through hole formed on the top surface of the horizontal fixed plate 12. A washer is inserted on the upper part of the screw part of the bolt.

[0026] By loosening the corresponding bolt, the screw part of the bolt can move and be finely adjusted along the corresponding waist-shaped through hole 131, so that the side limit block 13 can be moved and finely adjusted to ensure the accurate and firm clamping position of the aluminum alloy light box 100 to be processed.
[0027] Furthermore, a through hole 101 is formed on the bottom plate of the aluminum alloy light box 100, which communicates with and aligns with the upper through groove 121;
[0028] A pressing mechanism 30 is fixedly provided on the top surface of the top plate of the upper support frame 20. A lower pressing frame 32 is fixedly provided on the bottom surface of the lifting plate 31 of the pressing mechanism 30. The bottom of the lower pressing frame 32 is pressed against the top surface of the aluminum alloy light box 100;
[0029] A punching device 40 is fixedly provided on the top surface of the bottom plate part of the lower pressing frame 32. The punching knife 41 of the punching device 40 faces the through hole 101 and cooperates with the through hole 101.
[0030] Furthermore, a vertical baffle 1 is fixed to the rear part of the bottom surface of the top plate of the frame 10. The material receiving cart 50 is located in front of the vertical baffle 1. A permanent magnet block 51 is fixed to the rear wall surface of the material receiving cart 50, and an iron block 2 is fixed to the front wall surface of the vertical baffle 1. The permanent magnet block 51 is pressed against the front wall surface of the iron block 2 and adsorbed and fixed. The material receiving cart 50 is located directly below the middle blanking through groove 11, and the middle blanking through groove 11 faces the feeding port at the upper part of the material receiving cart 50. The material receiving cart 50 is pressed against the front wall surface of the iron block 2 by the permanent magnet block 51 and adsorbed and fixed to achieve positioning, making it not easy to move and ensuring the effect of waste material receiving.
[0031] Furthermore, the pressing mechanism 30 includes two upper pressing oil cylinders 33. The upper pressing oil cylinders 33 are fixed to the top surface of the top plate of the upper support frame 20. The bottom end of the push rod of the upper pressing oil cylinder 33 extends out of the bottom surface of the top plate of the upper support frame 20, and the bottom ends of the push rods of the two upper pressing oil cylinders 33 are fixed to the top surface of the same lifting plate 31.
[0032] The lower pressing frame 32 includes four side plate parts and a bottom plate part. The four side plate parts are formed on the top surfaces of the four edges of the bottom plate, and the adjacent sides of the adjacent two side plate parts are formed together;
[0033] Downward extending edge strips are formed on the four edges of the bottom surface of the bottom plate part. The upper part of the aluminum alloy light box 100 is located between the four edge strips. The inner side walls of the four edge strips are closely attached to the outer side walls of the corresponding side plates of the upper part of the aluminum alloy light box 100, and the bottom surface of the bottom plate part is pressed against the top surfaces of the four side plates of the aluminum alloy light box 100.
[0034] Furthermore, the punching device 40 includes a punching oil cylinder 42 fixed to the top surface of the bottom plate part of the lower pressing frame 32. The bottom end of the push rod of the punching oil cylinder 42 extends out of the bottom surface of the bottom plate part of the lower pressing frame 32 and is fixed with a punching connecting plate 43. A thickening block is fixed to the bottom surface of the punching connecting plate 43, and a punching knife 41 is provided on the bottom surface of the thickening block. The four outer side walls of the thickening block are aligned with the four outer side walls of the punching knife 41 up and down.
[0035] A plurality of vertical guide rods 44 are fixed to the top surface of the punching connecting plate 43, and the vertical guide rods 44 are inserted into the guide through holes formed on the bottom plate part of the lower pressing frame 32.
[0036] The punching knife 41 is a horizontally extending block, and a rectangular cutting knife part 411 is formed on the edge of its bottom surface. The outer side wall of the rectangular cutting knife part 411 is a vertical wall surface, and the inner side wall is an inclined wall surface.
[0037] When this embodiment is in use, first place the aluminum alloy light box 100 on the top surface of the horizontal fixed plate 12. The side vertical plates of the four side limit blocks 13 are closely attached to the outer side walls of the corresponding side plates of the aluminum alloy light box 100 to achieve fixation. It only needs to ensure that the through hole 101 of the aluminum alloy light box 100 communicates with and aligns with the upper through groove 121. When they are not aligned, the bolts need to be loosened to adjust the position of the side limit blocks 13 to ensure that the through hole 101 of the clamped aluminum alloy light box 100 communicates with and aligns with the upper through groove 121.
[0038] Then, driven by the push rods of all the upper pressing oil cylinders 33, the upper part of the aluminum alloy light box 100 is located between the four edge strips. The inner side walls of the four edge strips are closely attached to the upper outer side walls of the corresponding side plates of the aluminum alloy light box 100, and the bottom surface of the bottom plate part is pressed against the top surfaces of the four side plates of the aluminum alloy light box 100 to fix it. Then, driven by the push rod of the punching oil cylinder 42, the punching knife 41 quickly descends to punch off the excess edge material or burr waste on the inner side wall of the through hole 101 and drop it into the material receiving cart 50, which is convenient for subsequent dumping and processing.
[0039] Then, all components return to their original positions. Take out the processed aluminum alloy light box 100 and put a new aluminum alloy light box 100 for processing. The inner side wall of the through hole 101 of the processed aluminum alloy light box 100 is generally smooth. When there are still small burrs, only manual grinding is needed to remove them, which is very convenient. Its processing efficiency is high, greatly reducing the processing time and processing cost.
[0040] After using for a certain period of time, the bottom of the rectangular cutting knife part 411 may adhere to the waste or chips cut off by punching, and it needs to be manually cleaned regularly to ensure subsequent punching use. When punching cannot be performed for a certain period of time or the cut is uneven, the punching knife 41 needs to be removed and replaced.
[0041] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical fields can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
