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

[0032] Please refer to Figures 1 - 6 , the present utility model provides a steel pipe cutting device with a protection function, including an operating table 1, a chute 11 is provided on the operating table 1, a support frame 2 is fixedly connected to the outer wall of the operating table 1, a cutting mechanism 3 is provided on the support frame 2, and a pipe body 4 and a feeding device 5 are provided on the operating table 1.

[0033] In an embodiment of the present utility model, in order to be able to feed the pipe body 4, specifically, the feeding device 5 includes a motor 51, the motor 51 is fixedly connected to the inner wall of the operating table 1, a reciprocating screw 52, the reciprocating screw 52 penetrates the operating table 1 and is rotatably connected to the operating table 1, the reciprocating screw 52 is fixedly connected to the output end of the motor 51, a moving block 53, the moving block 53 is penetrated by the reciprocating screw 52 and is threadedly connected to the reciprocating screw 52, an extrusion plate 531 is fixedly connected to the outer wall of the moving block 53, a slider 54, the slider 54 is fixedly connected to the moving block 53, the slider 54 is slidably connected to the chute 11, a sliding rod 55, the sliding rod 55 penetrates the slider 54 and is slidably connected to the slider 54, a pressing block 56, the pressing block 56 is fixedly connected to the sliding rod 55, a fifth spring 57, one end of the fifth spring 57 is fixedly connected to the outer wall of the slider 54, and the other end of the fifth spring 57 is fixedly connected to the outer wall of the pressing block 56;

[0034] Further, the slider 54 is provided with a card slot 540, a push plate 541 is slidably connected to the inner wall of the card slot 540, a rod body 542 is fixedly connected to the outer wall of the push plate 541, the rod body 542 penetrates the slider 54 and is slidably connected to the slider 54, one end of a third spring 543 is fixedly connected to the outer wall of the rod body 542, the other end of the third spring 543 is fixedly connected to the outer wall of the slider 54, a clamping block 551 is slidably connected to the sliding rod 55, a fourth spring 552 is fixedly connected to the outer wall of the clamping block 551, the other end of the fourth spring 552 away from the clamping block 551 is fixedly connected to the inner wall of the sliding rod 55, a fixing block 13 is provided at one end of the chute 11, an inclined block 12 is provided at the other end of the chute 11, and the fixing block 13 and the inclined block 12 are fixedly connected to the operating table 1;

[0035] As Figure 1 and Figure 4 shown, in this state, the pressing block 56 tightly clamps the pipe body 4 under the extrusion of the inclined block 12, and the clamping block 551 is stuck inside the card slot 540. When the motor 51 is started, at this time, driven by the motor 51, the moving block 53 drives the slider 54 to move towards the cutting mechanism 3, and at the same time the pipe body 4 moves synchronously. When the moving block 53 moves below the cutting mechanism 3, at this time the fixing block 13 will extrude the rod body 542. During this process, the push plate 541 will extrude the clamping block 551, causing the clamping block 551 to move towards the inside of the sliding rod 55. When the clamping block 551 moves a certain distance, at this time the clamping block 551 will completely enter the inside of the sliding rod 55 under the elastic force of the fifth spring 57. At this time, the sliding rod 55 will return to its original position under the elastic force of the fifth spring 57, and at this time the pressing block 56 will release the clamping of the pipe body 4;

[0036] When the slider 54 returns under the drive of the motor 51, when the slider 54 moves to the right, at this time the sliding rod 55 will be squeezed by the inclined block 12, causing the sliding rod 55 to move. During this process, the clamping block 551 is squeezed by the slider 54, causing the clamping block 551 to move into the sliding rod 55. When the clamping block 551 coincides with the card slot 540, at this time the clamping block 551 will be clamped into the card slot 540 under the elastic force of the spring four 552, thus completing the clamping of the pipe body 4.

[0037] Furthermore, a first pressing plate 14 is slidably connected to the operating table 1. One end of a first spring 15 is fixedly connected to the outer wall of the first pressing plate 14, and the other end of the first spring 15 is fixedly connected to the inner wall of the operating table 1.

One end of a second spring 17 is fixedly connected to the outer wall of the second pressing plate 16, and the other end of the second spring 17 is fixedly connected to the inner wall of the operating table 1. Fixed rods 18 are fixedly connected to the outer walls of the first pressing plate 14 and the second pressing plate 16;

[0038] As Figure 2 and Figure 6 shown, when the moving block 53 moves to the left, at this time the pressing plate 531 will press the fixed rod 18, causing the first pressing plate 14 and the second pressing plate 16 to move, thereby clamping the pipe body 4 to prevent the pipe body 4 from shaking during cutting.

[0039] In the present utility model, during use, first start the motor 51. At this time, the pressing block 56 will drive the pipe body 4 to move towards the cutting mechanism 3. When the moving block 53 moves below the cutting mechanism 3, at this time the fixed block 13 will press the rod body 542, causing the push plate 541 to press the clamping block 551. During this process, the clamping block 551 will disengage from the card slot 540, causing the pressing block 56 to release the clamping of the pipe body 4. At the same time, the pressing plate 531 will press the fixed rod 18, causing the first pressing plate 14 and the second pressing plate 16 to move, thereby clamping the pipe body 4. Subsequently, start the cutting mechanism 3 to cut the pipe body 4. When the slider 54 returns to its original position under the drive of the motor 51, the sliding rod 55 will be squeezed by the inclined block 12. During this process, the clamping block 551 is squeezed by the slider 54, causing the clamping block 551 to move into the sliding rod 55. When the clamping block 551 coincides with the card slot 540, at this time the clamping block 551 will be clamped into the card slot 540 under the elastic force of the spring four 552, thereby clamping the pipe body 4 again.
