Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic pipe processing technology, specifically to an aluminum strip trimming device. Background Technology

[0002] In the processing of aluminum-plastic pipes, aluminum strips are usually bent into a tubular shape and wrapped around the outer wall of a plastic pipe. Then, the joints of the tubular structure formed by bending the aluminum strips are welded to form the aluminum-plastic pipe.

[0003] However, in actual processing, the width of the aluminum strip used is often greater than the outer diameter of the plastic tube. This makes it impossible for the processed aluminum tube structure to fit effectively against the outer wall of the plastic tube. At the same time, if the side of the aluminum strip is uneven, the weld of the formed aluminum tube will be uneven, resulting in gaps after welding. Therefore, an aluminum strip trimming device is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aluminum strip cutting device, which solves the problem that when processing aluminum-plastic pipes, the width of the aluminum strip must be greater than the outer diameter of the plastic pipe. This makes it impossible for the processed aluminum pipe structure to effectively fit the outer wall of the plastic pipe. In addition, if the side of the aluminum strip is uneven, the weld seam of the formed aluminum pipe will be uneven, resulting in gaps after welding.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an aluminum strip trimming device, comprising a support part and a loading part movably installed on both sides of the top of the support part, wherein a cutting part is installed in each of the two loading parts;

[0006] The cutting section includes an upper pressure blade and a lower pressure blade arranged opposite each other. A material feeding gap is formed on the inner side of the upper pressure blade and the waste material gap is formed on the outer side of the upper pressure blade and the waste material gap. The material feeding gap and the waste material gap are staggered vertically to form a cutting area. The aluminum strip passes through the cutting area to cut and form a central material and waste materials on both sides.

[0007] Preferably, the support includes a support base plate and guide rails fixedly welded to both sides of the top of the support base plate, and the loading part slides along the guide rails.

[0008] Preferably, the loading part includes a mounting frame and a positioning slider fixedly welded to the bottom of the mounting frame, the positioning slider being slidably disposed on the outer wall of the guide rail.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides an aluminum strip trimming device, which solves the problem that when processing aluminum-plastic pipes, the width of the aluminum strip must be greater than the outer diameter of the plastic pipe. This makes it impossible for the processed aluminum pipe structure to effectively fit the outer wall of the plastic pipe. At the same time, if the side of the aluminum strip is uneven, the weld of the formed aluminum pipe will be uneven, resulting in gaps after welding.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses an aluminum strip trimming device, according to the attached... Figure 1-4 As shown, it includes a support part 1 and a loading part 2 movably installed on both sides of the top of the support part 1, and a cutter part 3 is installed in both loading parts 2.

[0024] The cutting section 3 includes an upper pressing blade 31 and a lower pressing blade 32 arranged opposite each other. The inner side of the upper pressing blade 31 and the lower pressing blade 32 forms a material feeding gap 33, and the outer side of the upper pressing blade 31 and the lower pressing blade 32 forms a waste material gap 35. The material feeding gap 33 and the waste material gap 35 are offset vertically to form a cutting area. The aluminum strip passes through the cutting area to cut and form the middle material and the waste on both sides.

[0025] The support part 1 includes a support base plate 11 and guide rails 12 fixedly welded to both sides of the top of the support base plate 11. The loading part 2 slides along the guide rails 12.

[0026] The loading unit 2 includes a mounting frame 21 and a positioning slider 22 fixedly welded to the bottom of the mounting frame 21. The positioning slider 22 is slidably disposed on the outer wall of the guide rail 12.

[0027] A bidirectional lead screw 13 is rotatably mounted in the middle of the support base plate 11, and a connecting block 23 is fixedly mounted at the bottom of the mounting frame 21. The connecting blocks 23 on both sides are threaded to the outer surfaces of the two ends of the bidirectional lead screw 13.

[0028] Support seats 24 are fixedly mounted on the upper and lower sides of the mounting frame 21, respectively. Servo motors 34 are fixedly mounted on the outer sides of the upper pressure knife 31 and the lower pressure knife 32, respectively. The servo motors 34 are fixedly mounted in the support seats 24.

[0029] A pad 25 is provided between the two sets of support seats 24. The side walls of the two sets of support seats 24 are provided with support column mounting grooves 26. The distance between the two sets of support seats 24 can be adjusted by installing support columns of different lengths in the support column mounting grooves 26.

[0030] The inner wall of the mounting frame 21 is integrally formed with a guide strip 28, and the outer wall of the support base 24 is provided with a guide groove 27 adapted to the guide strip 28.

[0031] Working principle: First, by rotating the bidirectional lead screw 13, the two sets of mounting frames 21 move towards or away from each other along the guide rail 12, thereby changing the spacing between the support seats 24 on both sides to meet the needs of aluminum strip products of different widths.

[0032] Then, by installing support columns between the upper and lower sets of support seats 24, with both ends of the support columns installed in the support column mounting grooves 26, the height of the feeding gap 33 and the scrap gap 35 is adapted to the thickness of the aluminum strip. It should be noted that when the inner top of the feeding gap 33 is flush with the inner bottom of the scrap gap 35, the feeding gap 33 is in its maximum thickness state to ensure that the cutting area can completely cut the aluminum strip.

[0033] The width of the entire feeding gap 33 is made to be the same as the required aluminum strip width. Then the aluminum strip is inserted from the middle and continuously cut through the cutting area between the upper pressure knife 31 and the lower pressure knife 32. The cut waste is discharged from the waste gaps 35 on both sides, while the finished product moves forward through the feeding gap 33 into the forming machine for aluminum-plastic tube production. This ensures that the width of the cut aluminum strip meets the usage requirements and that the sides are flat.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
