Description

Technical Field

[0001] This utility model belongs to the technical field of tower angle steel shearing machines, and specifically relates to a tower angle steel shearing machine with rapid alignment. Background Technology

[0002] In the production of angle steel, the process begins with cutting longer raw materials into specified dimensions. The working principle of an angle steel shearing machine is that the upper and lower dies on the slide are engaged by a punch press to cut the angle steel. If the cut angle steel is not supported by a timely material support mechanism, it will fall to the ground. During this process, the angle steel may be damaged, and long-term use may even damage the ground below where the angle steel falls.

[0003] The utility model disclosed in CN203265769U is a telescopic material support frame for an angle steel shearing machine, including a V-shaped fixed frame and at least two sets of material support wheels arranged on the V-shaped fixed frame. A V-shaped bracket is provided in front of the V-shaped fixed frame, and at least one set of material support wheels is provided on the V-shaped bracket. The V-shaped bracket is fixedly connected to the front end of three telescopic sliding shafts arranged in a V-shape. The front end of the V-shaped fixed frame is fixedly provided with a guide positioning sleeve corresponding to the telescopic sliding shaft. The rear ends of the three telescopic sliding shafts extend into their respective guide positioning sleeves and are slidably connected to the guide positioning sleeves.

[0004] However, existing cutting machines do not have the function of aligning and positioning workpieces, which results in workpieces of varying lengths and low cutting accuracy when cutting angle steel. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0034] like Figures 1 to 8 As shown, a rapid alignment tower angle steel shearing machine includes a worktable 1, a gantry frame 4 fixedly mounted on the worktable 1, a sliding plate 16 slidably mounted on the gantry frame 4, a cutting blade 7 detachably mounted on the sliding plate 16, a first driving component 5 for moving the sliding plate 16 between the gantry frame 4 and the sliding plate 16, a first guide rod 10 and a support column 11 fixedly mounted on the worktable 1, a support plate 20 slidably mounted on the first guide rod 10 and the support column 11, a limit mechanism between the support plate 20 and the support column 11, the limit mechanism fixing the support plate 20 to the support column 11, and a positioning plate 22 fixedly mounted on the support plate 20.

[0039] In actual operation: the workpiece is pushed to move along the worktable 1. When the end of the workpiece contacts the positioning plate 22, the workpiece is aligned and positioned. The support plate 20 is dragged to move along the support column 11. At the same time, the support plate 20 moves along the first guide rod 10. When it moves to the designated position, the operating limit bolt 27 drives the arc block 26 to move along the arc groove 24. The arc block 26 contacts the support column 11.

[0044] Specifically: the elastic component 2806 is a return spring.

[0045] In actual operation: the end of the workpiece pushes the moving plate 2805 to move, and the moving plate 2805 drives the positioning rod and piston plate 2802 to move along the detection cavity 2801, so that the first detection contact 2808 contacts the second detection contact 2809 to realize the function of automatic positioning. At the same time, the elastic component 2806 is compressed. After the cutting is completed, the elastic component 2806 drives the first detection contact 2808 to reset, realizing the function of repeated automatic positioning. Example

[0046] Based on Embodiment 1, a plurality of linearly uniformly distributed first guide rollers 3 are rotatably mounted on the worktable 1, and two symmetrical support frames are slidably mounted on the worktable 1. A plurality of linearly uniformly distributed second guide rollers 17 are rotatably mounted on each of the two support frames. A second drive component 15 is detachably mounted on the worktable 1. The output end of the second drive component 15 is connected to the two support frames through a transmission mechanism. When the second drive component 15 is started, it drives the two support frames to move synchronously relative to each other or in opposite directions through the transmission mechanism.

[0047] The transmission mechanism includes a double threaded rod 14 rotatably mounted on the workbench 1. The power end of the second drive component 15 is connected and fixed to the double threaded rod 14 via a rotating shaft. Both support frames are provided with first threaded holes 19. The double threaded rod 14 is threadedly installed in the two first threaded holes 19. The thread directions of the two first threaded holes 19 are opposite. A second guide rod 13 is fixedly installed on the workbench 1. The two support frames are provided with second guide holes 18. The second guide rod 13 is guided and installed in the second guide holes 18.

[0048] Specifically: Multiple first rotating shafts 2 are rotatably mounted on the worktable 1, and the first guide rollers 3 are fixedly mounted on the first rotating shafts 2. The second drive component 15 is a forward and reverse servo motor. Two symmetrical second mounting holes 9 are opened on the worktable 1.

The double threaded rod 14 is provided with two external threads with opposite thread directions, and the two external threads correspond to the threads of the two first threaded holes 19.

[0049] In actual operation: the second drive component 15 is activated to drive the two support frames to move through the double threaded rod 14. The support frames drive the two sets of second guide rollers 17 to move synchronously. The two second rotating rollers clamp the workpiece and center it, thereby guiding and positioning the workpiece.

[0050] The working principle of this utility model is as follows: The workpiece is pushed to move along the worktable 1. When the end of the workpiece contacts the positioning plate 22, the workpiece is aligned and positioned. The support plate 20 is dragged along the support column 11, and simultaneously, the support plate 20 moves along the first guide rod 10. When it reaches the designated position, the operating limit bolt 27 drives the arc block 26 to move along the arc groove 24. The arc block 26 contacts the support column 11, and the friction between the arc block 26 and the support column 11 connects and fixes the support plate 20 to the support column 11. This is suitable for cutting workpieces of different lengths. The end of the workpiece pushes the moving plate 2805 to move. The moving plate 2805 drives the positioning rod and piston plate 2802 to move along the detection cavity 2801, causing the first detection contact 2808 to contact the second detection contact 2809, achieving automatic positioning. Simultaneously, the elastic component 2806 is compressed. After cutting, the elastic component 2806 drives the first detection contact 2808 to reset, achieving repeated automatic positioning.
