Description

Technical Field

[0001] This utility model relates to the field of round steel cutting technology, specifically a fixed-length cutting device. Background Technology

[0002] Round steel refers to solid, long strips of steel with a circular cross-section. Round steel specifications are expressed in millimeters of diameter. Round steel is available in three types: hot-rolled, forged, and cold-drawn. Hot-rolled round steel ranges in size from 5.5 to 250 mm. Smaller round steel bars (5.5–25 mm) are mostly supplied in straight bundles and are commonly used as reinforcing bars, bolts, and various machine parts. Round steel bars larger than 25 mm are mainly used for manufacturing machine parts or as seamless steel pipe blanks.

[0003] When it is necessary to cut round steel to a fixed length, the existing technology mostly involves workers first using a ruler to measure and mark the round steel before cutting it. This is time-consuming and labor-intensive, and is easily affected by the measurement, resulting in inconsistent lengths. Therefore, there is an urgent need for a fixed-length cutting device to solve the above problems. Utility Model Content

[0035] In this embodiment of the utility model, please refer to Figures 1 to 3 A fixed-length cutting device includes a fixed plate frame 1, and further includes:

[0036] Connecting roller 5 is rotatably connected to fixed plate frame 1. Several sets of connecting roller 5 are provided and arranged in a straight line.

[0037] A fixed-length conveying mechanism, connected to a fixed frame 1, is used for conveying round bars to a fixed length. The fixed-length conveying mechanism includes: a connecting roller 6, rotatably connected to the fixed frame 1, with its top abutting against the bottom of the round bar; a fixed rod 13, fixedly connected to the fixed frame 1; a rotating disk 14, rotatably connected to the fixed rod 13, with its bottom abutting against the top of the round bar; an equal-angle rotation assembly, one end connected to the fixed frame 1 and the other end connected to the rotating disk 14, used to drive the rotating disk 14 to rotate at equal angles; and a limiting assembly, one end connected to the fixed frame 1 and the other end abutting against the rotating disk 14, used to limit the rotation of the rotating disk 14.

[0038] Connecting roller 3 7 is rotatably connected to fixed plate frame 1. Several sets of connecting roller 3 7 are provided and are arranged symmetrically about the round steel.

[0039] The telescopic component 8 is connected at its bottom end to the fixed plate frame 1;

[0040] The cutting machine 9 is connected to the top of the telescopic component 8.

[0041] The round steel is placed on connecting roller 5 and connecting roller 6. The equal-angle rotation assembly drives the rotating disk 14 to rotate at equal angles. The rotating disk 14 conveys the round steel to a fixed length. The telescopic component 8 drives the cutting machine 9 to move longitudinally. The cutting machine 9 cuts the round steel.

[0042] As one embodiment of this utility model, please refer to Figures 1 to 3 The constant-angle rotation assembly includes:

[0043] The driving component 10 is connected to the fixed plate frame 1;

[0044] Connector 11 is connected to the output terminal of drive component 10;

[0045] Connecting rod 12 is connected to connecting plate 11. The connecting rod 12 is provided in several groups and is arranged in a circumferential manner with equal spacing.

[0046] The protrusion 15 is connected to the rotating disk 14. The protrusion 15 is provided in several groups and is arranged in a circumferential manner with equal spacing.

[0047] Rotating sleeve 16 is rotatably connected to fixed rod 13;

[0048] The spiral spring 17 has one end connected to the rotating sleeve 16 and the other end connected to the fixed rod 13;

[0049] The connecting plate 18 is connected to the rotating sleeve 16;

[0050] The folding rod 19 is connected to the connecting plate 18;

[0051] The abutting sleeve 20 is rotatably connected to the folding rod 19 and abuts against the connecting plate 18;

[0052] The spiral spring 21 has one end connected to the folding rod 19 and the other end connected to the abutment sleeve 20.

[0053] The driving component 10 drives the connecting plate 11 to rotate, which in turn drives the connecting rod 12 to rotate. When the connecting rod 12 rotates to abut against the connecting plate 18, it drives the connecting rod 18 to rotate synchronously. The connecting rod 18 drives the abutting sleeve 20 to rotate, causing the abutting sleeve 20 to abut against the protrusion 15. This causes the rotating disk 14 to rotate synchronously, and the rotating disk 14 transports the round steel. When the connecting rod 12 disengages from the connecting plate 18, the reaction force of the spiral spring 17 causes the connecting plate 18 to return to its original position. The connecting plate 18 then drives the abutting sleeve 20 to return to its original position. During this process, the abutting sleeve 20 will collide with the protrusion 15, causing the abutting sleeve 20 to rotate. The limiting component prevents the rotating disk 14 from rotating in the opposite direction due to the collision between the abutting sleeve 20 and the protrusion 15. The spiral spring 21 ensures that the abutting sleeve 20 can return to its original position. The driving component 10 can be a stepper motor, servo motor, etc.

[0054] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The limiting component includes:

[0055] Fixed plate 22 is connected to fixed plate frame 1;

[0056] The telescopic rod 23 is connected at one end to the fixed plate 22;

[0057] It abuts against the arc plate 24, connects to the other end of the telescopic rod 23, and abuts against the rotating disk 14;

[0058] The elastic element 25 is connected at one end to the fixed plate 22 and at the other end to the abutting arc plate 24.

[0059] The abutting arc plate 24 abuts against the rotating disk 14, so that the rotating disk 14 can only rotate in one direction by the drive of the abutting sleeve 20. When the connecting plate 18 drives the abutting sleeve 20 back to its original position, the rotating disk 24 will not rotate in the opposite direction due to the movement of the abutting sleeve 20. The elastic element 25 can be a spring, a sheet spring, etc.

[0060] In this embodiment, the side of the abutting arc plate 24 that abuts against the rotating disk 24 is provided with an anti-slip pad or anti-slip texture.

[0061] As one embodiment of this utility model, please refer to Figure 1 It also includes:

[0062] The movable wheel 2 is connected to the bottom of the fixed plate frame 1.

[0063] The movable wheels 2 facilitate the movement and handling of the device.

[0064] As one embodiment of this utility model, please refer to Figure 1 It also includes a fixing mechanism for fixing the bottom connection of the plate frame 1, and for fixing the plate frame 1. The fixing mechanism includes:

[0065] The fixing sleeve 3 is connected to the bottom of the fixing plate frame 1;

[0066] Rotating sleeve 4 is threadedly connected to fixed sleeve 3.

[0067] When it is necessary to fix the fixed plate frame 1, the rotating sleeve 4 is rotated so that the rotating sleeve 4 moves downward until it comes into contact with the ground, thereby fixing the fixed plate frame 1.

[0068] The working principle of this utility model is as follows: Round steel is placed on connecting roller 5 and connecting roller 6. The driving component 10 drives the connecting disc 11 to rotate, which in turn drives the connecting rod 12 to rotate. When the connecting rod 12 rotates to abut against the connecting plate 18, it drives the connecting rod 18 to rotate synchronously. The connecting rod 18 then drives the abutting sleeve 20 to rotate, causing the abutting sleeve 20 to abut against the protrusion 15, which in turn drives the rotating disc 14 to rotate synchronously. The rotating disc 14 conveys the round steel. When the connecting rod 12 disengages from the connecting plate 18, the spiral spring... Under the reaction force of 17, the connecting plate 18 returns to its original position. The connecting plate 18 drives the abutting sleeve 20 back to its original position. During the process, the abutting sleeve 20 will collide with the protrusion 15, causing the abutting sleeve 20 to rotate. The abutting arc plate 24 abuts against the rotating disk 14 to prevent the rotating disk 14 from rotating in the opposite direction due to the collision between the abutting sleeve 20 and the protrusion 15. The setting of the spiral spring 21 ensures that the abutting sleeve 20 can return to its original position. The telescopic component 8 drives the cutting machine 9 to move longitudinally, and the cutting machine 9 cuts the round steel.
