Description

Technical Field

[0001] This utility model relates to the field of laser cutting processing technology, and in particular to a device for precision sheet metal laser cutting processing. Background Technology

[0002] Precision sheet metal processing is a high-precision machining process for thin metal sheets. It is an advanced form of sheet metal processing. Its core feature is that the thickness of the parts remains unchanged during the processing. It also has advantages such as high precision, high quality and dimensional stability. It usually uses a laser beam emitted by a laser cutting machine to cut the precision sheet metal.

[0003] Precision sheet metal encompasses various shapes such as rectangles, circles, and polygons. When cutting tubular sheet metal, existing devices generally use a method of clamping and fixing one end of the tubular sheet metal, and then using a laser cutting head to divide it into multiple shorter tubes. However, during the cutting process, since only one end of the tubular sheet metal is fixed, when the cutting is nearing its end, the unfixed end is prone to sudden breakage under gravity due to the lack of effective support. This breakage not only causes burrs at the cut but also severely damages the flatness of the cut surface. Therefore, a device for precision sheet metal laser cutting is proposed.

[0034] Example 1

[0035] Reference Figures 1-3 The first embodiment of this utility model provides a precision sheet metal laser cutting processing device, including: a cutting unit 100, a rotating unit 200, a clamping unit 300, a supporting unit 400, and a material discharge unit 500.

[0036] The cutting unit 100 includes a processing table 101 and a support frame 102 fixedly connected to the top of the processing table 101. A cutting assembly 103 for cutting precision sheet metal is provided below the support frame 102.

[0037] The rotating unit 200 is mounted on the processing table 101. The rotating unit 200 is equipped with a clamping unit 300. The rotating unit 200 is used to drive the clamping unit 300 to rotate. The clamping unit 300 is used to clamp and fix the precision sheet metal.

[0038] The support unit 400 is mounted on the processing table 101 and is used to support the precision sheet metal.

[0039] The discharge unit 500 is mounted on the support unit 400 and is used to discharge the cut precision sheet metal from the support unit 400.

[0040] One end of the tubular precision sheet metal is fixed by the clamping unit 300, while the other end is supported by the support unit 400. The rotating unit 200 can drive the tubular sheet metal to rotate, so that the laser cutting component 1033 can divide the tubular sheet metal into multiple shorter tubular sheet metals. During the cutting process, the support unit 400 can prevent the tubular sheet metal from detaching before it is completely cut, so that the tubular sheet metal can be cut completely to ensure the flatness of the cut surface. The material discharge unit 500 can discharge the cut tubular sheet metal from the support unit 400, so that the cutting component 103 can continuously perform cutting operations.

[0041] Example 2

[0042] Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, the cutting component 103 includes a cross electric slide rail 1031 fixedly connected to the bottom of the support frame 102. An electric lifting rod 1032 is fixedly connected to the bottom of the output end of the cross electric slide rail 1031, and a laser cutting component 1033 is fixedly connected to the bottom of the output end of the electric lifting rod 1032.

[0043] The cross-shaped electric slide rail 1031 is composed of two electric slide rails connected in a cross manner. The cross-shaped electric slide rail 1031 can drive the electric lifting rod 1032 to move in the X and Y planes. The electric lifting rod 1032 is used to drive the laser cutting part 1033 to lift and lower, so that the laser cutting part 1033 can adapt to tubular sheet metal of different diameters and lengths. The bottom of the laser cutting part 1033 is provided with a laser cutting head to perform laser cutting on the tubular sheet metal.

[0044] Example 3

[0045] Reference Figure 1 and Figure 2This is the third embodiment of the present invention. Unlike the previous embodiment, the rotating unit 200 includes a motor base 201 fixedly connected to the top of the processing table 101. A servo motor 202 is fixedly connected to one side of the motor base 201, and the output shaft of the servo motor 202 slides through the motor base 201.

[0046] The output shaft of the servo motor 202 passes through the motor base 201 and can rotate. The servo motor 202 is used to drive the clamping unit 300 to rotate. When the diameter of the tubular sheet metal is small and the wall is thin, it is directly cut by the laser cutting part 1033. When the diameter of the tubular sheet metal is large and the wall is thick, the servo motor 202 drives the tubular sheet metal to rotate so that the laser of the laser cutting part 1033 can penetrate the wall of the tubular sheet metal and complete the cutting.

[0047] Specifically, the clamping unit 300 includes a square cover 301 fixedly connected to the output end of the servo motor 202. Two symmetrically distributed electric push rods 302 are fixedly installed on the side wall of the square cover 301. The output ends of the two electric push rods 302 pass through the square cover 301 and are fixedly connected to a clamping plate 303.

[0048] The output end of the electric push rod 302 slides through the interior of the square cover 301. When the tubular sheet metal is placed between the two clamping plates 303, the two electric push rods 302 bring the two clamping plates 303 closer together and clamp and fix the tubular sheet metal. The servo motor 202 can drive the square cover 301 to rotate.

[0049] Example 4

[0050] Reference Figures 1-3 This is the fourth embodiment of the present utility model. Unlike the previous embodiment, the support unit 400 includes an electric push cylinder 401 fixedly installed on the top of the processing table 101. The output end of the electric push cylinder 401 is fixedly connected to an L-shaped plate 402. The L-shaped plate 402 is provided with a support component 403 for supporting the precision plate.

[0051] Once the tubular sheet metal is clamped, the electric push cylinder 401 drives the L-shaped plate 402 to move toward the square cover 301, so that the other end of the tubular sheet metal is supported by the support component 403.

[0052] It should be noted that the support assembly 403 includes a support block 4031 located above the L-shaped plate 402. The top of the support block 4031 is provided with an arc-shaped groove. The bottom of the support block 4031 is rotatably connected to a round rod 4032 and a threaded rod 4033. Both the round rod 4032 and the threaded rod 4033 pass through the L-shaped plate 402, and the threaded rod 4033 is threadedly connected to the L-shaped plate 402.

[0053] During the segmentation process, the tubular sheet metal is cut near the support block 4031. The tubular sheet metal can be placed in the arc-shaped groove of the support block 4031 so that the end of the tubular sheet metal is supported by the support block 4031, so that the tubular sheet metal will not break due to its own weight during the cutting process. The height of the support block 4031 can be adjusted by rotating the threaded rod 4033 so that the support block 4031 can adapt to tubular sheet metal of different diameters. The round rod 4032 slides through the L-shaped plate 402 and is used to prevent the support block 4031 from shifting during the lifting and lowering process.

[0054] Specifically, the discharge unit 500 includes an arc plate 501 that is slidably disposed in the arc groove of the support block 4031. A T-shaped rod 502 is fixedly connected to one side of the arc plate 501. One end of the T-shaped rod 502 slides through the support block 4031. A spring 503 is sleeved on the T-shaped rod 502. A vertical plate 504 is fixedly connected to the top of the electric push cylinder 401.

[0055] The T-shaped bar 502 is compressed by the spring 503, keeping it away from the support block 4031. When the tubular sheet metal is placed in the arc groove of the support block 4031, one end of the tubular sheet metal contacts the arc plate 501. After cutting, the electric push cylinder 401 drives the L-shaped plate 402 to move towards the vertical plate 504. When the T-shaped bar 502 abuts against the vertical plate 504, the arc plate 501 stops moving. During the movement of the support block 4031, the T-shaped bar 502 and the support block 4031 will compress the spring 503, and the cut tubular sheet metal located in the arc groove will be abutted by the arc plate 501, causing the cut tubular sheet metal to fall off the support block 4031.

[0056] Subsequently, the electric push cylinder 401 drives the L-shaped plate 402 to move towards the square cover 301, so that the T-shaped rod 502 is no longer in contact with the vertical plate 504. Then, the spring 503 restores its elasticity and pushes the T-shaped rod 502 away from the support block 4031, and causes the arc plate 501 to move and reset. This allows the cut tubular sheet metal to be detached from the support block 4031, and the support block 4031 to continue to support the clamped tubular sheet metal, thereby improving the efficiency of cutting and processing the tubular sheet metal.

[0057] In addition, a discharge cover 505 is fixedly connected to the bottom of the processing table 101, and a discharge port that fits the discharge cover 505 is opened on the top of the processing table 101.

[0058] When the T-shaped bar 502 comes into contact with the vertical plate 504, the tubular sheet metal pushed down by the arc plate 501 will fall downwards, allowing it to pass through the discharge port and fall into the discharge cover 505. The bottom of the discharge cover 505 is inclined to facilitate the discharge of the cut tubular sheet metal for subsequent processing.

[0059] During use, the tubular sheet metal is placed between two clamping plates 303. Then, two electric push rods 302 are used to clamp and fix the tubular sheet metal between the two clamping plates 303. Subsequently, the electric push cylinder 401 drives the L-shaped plate 402 to move towards the square cover 301, so that the other end of the tubular sheet metal is above the support block 4031. Then, the threaded rod 4033 is rotated so that the tube wall of the tubular sheet metal is in the arc groove of the support block 4031. Then, the cross electric slide rail 1031 drives the electric lifting rod 1032 to move. The electric lifting rod 1032 drives the laser cutting part 1033 to descend. The servo motor 202 can drive the square cover 301 to rotate so that the laser cutting part 1033 can perform laser cutting on the tubular sheet metal.

[0060] After cutting, the electric push cylinder 401 moves the L-shaped plate 402, so that the T-shaped rod 502 abuts against the vertical plate 504. The arc plate 501 then pushes the tubular sheet metal to be cut off from the support block 4031, causing it to fall into the discharge hood 505. The cut tubular sheet metal is then discharged through the discharge hood 505. Subsequently, the electric push cylinder 401 drives the L-shaped plate 402 to move towards the square cover 301. When the T-shaped rod 502 is no longer in contact with the vertical plate 504, the spring 503 drives the arc plate 501 to automatically reset. Then, the support block 4031 continues to support the clamped tubular sheet metal, and the laser cutting part 1033 cuts it. This allows for continuous cutting and improves the efficiency of segmenting and processing tubular sheet metal.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
