[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a round steel cutting saw, including a cutting table 1, an industrial control host 2 fixedly connected to the front of the cutting table 1, a support frame 3 fixedly connected to the upper surface of the cutting table 1, a cutting box 4 fixedly connected to the front of the support frame 3, a saw blade 5 connected to the lower surface of the cutting box 4, a telescopic cylinder 6 fixedly connected to the upper surface of the cutting table 1, a feeding assembly 7 fixedly connected to the output end of the telescopic cylinder 6, an equidistant assembly 8 fixedly connected to the inner wall of the feeding assembly 7, a pressing assembly 9 fixedly connected to the upper surface of the feeding assembly 7, and an auxiliary assembly 10 fixedly connected to the left side of the feeding assembly 7.

[0021] The feeding component 7 is used to automatically push the round steel for cutting operations, the clamping component 9 is used to improve the stability of the round steel during the cutting process, the equidistant component 8 is used to ensure that each segment of the round steel is of the same length when it is cut, and the auxiliary component 10 is used to provide support for the other end of the round steel.

[0022] Furthermore, the feeding assembly 7 includes a feeding table 701, the inner wall of which is provided with an arc-shaped groove. The feeding table 701 is slidably connected to the upper surface of the cutting table 1. The telescopic cylinder 6 can drive the feeding table 701 to move closer to the saw blade 5, thereby facilitating the cutting operation of the round steel.

[0023] Furthermore, the equidistant component 8 includes a first servo motor 801, the output end of which is fixedly connected to a first lead screw 802. A second servo motor 803 is fixedly connected to the inner wall of the feeding table 701, the output end of which is fixedly connected to a second lead screw 804. A strip plate 805 is slidably connected to the inner bottom wall of the feeding table 701. A push plate 806 is fixedly connected to the upper surface of the strip plate 805. A transmission plate 807 is fixedly connected to the left side of the strip plate 805. The transmission plate 807 is threadedly connected to the first lead screw 802. After the first servo motor 801 is started, it can drive the strip plate 805 to move backward through the transmission plate 807, thereby driving the round steel to move backward through the push plate 806.

[0024] Furthermore, a movable plate 808 is slidably connected to the inner bottom wall of the feeding table 701. The movable plate 808 is threadedly connected to the second lead screw 804. A contact switch 809 is fixedly connected to the front of the movable plate 808. The position of the contact switch 809 corresponds to the position of the strip plate 805. When the strip plate 805 moves backward, it can touch the contact switch 809 on the front of the movable plate 808. When the contact switch 809 is activated by pressure, it can automatically shut down the first servo motor 801 and turn on the second servo motor 803. The first servo motor 801 stops moving the strip plate 805, and at the same time, the second servo motor 803 drives the movable plate 808 to move backward by the same distance, which facilitates the equidistant cutting operation of the round steel.

[0025] Furthermore, the clamping assembly 9 includes an electric push rod 901. The inner wall of the feeding table 701 is provided with a sliding groove. A movable plate 902 is slidably connected to the inner wall of the sliding groove. The output end of the electric push rod 901 is fixedly connected to the upper surface of the movable plate 902. An arc-shaped pressure plate 903 is fixedly connected to the right side of the movable plate 902. The position of the arc-shaped pressure plate 903 corresponds to the position of the arc-shaped groove. The electric push rod 901 can drive the movable plate 902 to move up and down in the sliding groove. When the movable plate 902 moves to the bottom end in the sliding groove, the arc-shaped pressure plate 903 can restrict and press the surface of the round steel in the arc-shaped groove to ensure that the round steel will not detach from the arc-shaped groove.

[0026] Furthermore, the auxiliary component 10 includes a connecting frame 1001. A support plate 1002 is fixedly connected to one end of the connecting frame 1001 away from the feeding table 701. A positioning frame 1003 is fixedly connected to the back of the support plate 1002. A threaded rod 1004 is rotatably connected to the back of the positioning frame 1003. A rectangular plate 1005 is slidably connected to the inner bottom wall of the positioning frame 1003. Two support rods 1006 are fixedly connected to the front of the rectangular plate 1005. The front ends of the two support rods 1006 extend to the front of the support plate 1002 and are fixedly connected to a support sleeve 1007. The position of the support sleeve 1007 is aligned with the position of the arc-shaped groove. Correspondingly, the front end of the threaded rod 1004 is rotatably connected to the inner front wall of the positioning frame 1003, and the rectangular plate 1005 is threadedly connected to the threaded rod 1004. The front of the positioning frame 1003 has two rectangular through holes that are adapted to the support rods 1006. Rotating the threaded rod 1004 can drive the rectangular plate 1005 to move forward in the positioning frame 1003, thereby adjusting the front and rear positions of the support sleeve 1007 through the two support rods 1006. This facilitates the support sleeve 1007 to always support the rear end of the round steel when cutting round steel to different lengths, thus improving the stability of the round steel during the cutting process.

[0027] Working principle: First, the round steel is placed in the arc-shaped groove on the feeding table 701. At this time, the single movement distance of the movable plate 808 is adjusted by the industrial control host 2 to cut the round steel into different lengths. After the adjustment is completed, the second servo motor 803 drives the movable plate 808 to move to the designated position through the second lead screw 804. At this time, the electric push rod 901 is opened, and the electric push rod 901 drives the movable plate 902 and the arc-shaped pressure plate 903 to descend. The arc-shaped pressure plate 903 can restrict the round steel in the arc-shaped groove. At the same time, according to the required length of the round steel, the threaded rod 1004 is rotated, so that the rectangular plate 1005 drives the two support rods 1006 to move forward, thereby driving the support sleeve 1007 to move forward, so that the rear end of the round steel is inserted into the support sleeve 1007. At this time, the first servo motor 801 is started, and the first lead screw 802 drives the transmission plate 807 to move backward, thereby driving the strip plate 805 and the push plate 806 to move backward until the push plate 806 is in contact with the front end of the round steel. Upon contact, the first servo motor 801 stops, and the telescopic cylinder 6 moves the feeding table 701 to the right, allowing the round steel to be cut by the saw blade 5. After cutting, the telescopic cylinder 6 moves the feeding table 701 back to its original position, while the first servo motor 801 moves the strip plate 805 backward. The push plate 806 pushes the front end of the round steel, moving it backward until the back of the strip plate 805 contacts the contact switch 809. At this point, the contact switch 809 automatically shuts off the first servo motor 801 and turns on the second servo motor 803, which in turn drives the second lead screw 804 to move the movable plate 808 backward a fixed distance. The rear end of the round steel is then inserted into the support sleeve 1007. Simultaneously, the telescopic cylinder 6 restarts and moves the feeding table 701 to the right, thus cutting the round steel. This eliminates the need for manual measurement and pushing of the round steel by the operator, greatly improving the cutting quality and efficiency.
