Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to a clamping and cutting device for building pipes. Background Art

[0002] Before use, building pipes need to be cut for subsequent use according to requirements. When cutting, it is necessary to clamp them to avoid the influence of shaking during cutting on the cutting.

[0003] However, in the traditional pipe clamping device, it cannot be flexibly adjusted according to the diameter of the pipe during fixed clamping, and the cutting machine cannot move according to the required length during cutting. Therefore, a clamping and cutting device for building pipes is needed to solve the above technical problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a clamping and cutting device for building pipes, which can effectively solve the technical problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A clamping and cutting device for building pipes includes a processing block. A receiving groove is formed on the top surface of the processing block. Symmetric vertical blocks are fixed to the inner bottom of the receiving groove. Sliding grooves are formed on the side walls of the symmetric vertical blocks. Sliders are slidably connected in the sliding grooves. A driven block is fixed between the two sliders. A trapezoidal block is fixed to the top end of the driven block. A vertical rod is fixed to the top surface of the trapezoidal block. Limiting blocks are provided at both ends of the vertical rod. A first roller is rotatably connected to the vertical rod.

[0007] As a further solution of the utility model, connecting rods are fixedly connected to the inner walls of the receiving groove on both sides of the vertical rod. Swing arms are rotatably connected to the connecting rods. The side wall of the swing arm is in contact with the limiting block.

[0008] As a further solution of the utility model, a second roller is rotatably connected to the end of the swing arm. The second roller is in contact with the outer wall of the trapezoidal block. A third roller is rotatably connected to the other end of the swing arm.

[0009] As a further solution of the utility model, fixing blocks are fixed to both ends of the top surface of the processing block. Adjusting grooves are formed in the fixing blocks.

[0010] As a further solution of the utility model, threaded rods are rotatably connected to the inner walls on both sides of the adjusting groove. Driven telescopic blocks are threadedly connected to the threaded rods. A cutting machine is fixedly connected to the end of the driven telescopic block.

[0011] As a further solution of the utility model, when the driven telescopic blocks on both sides extend to the maximum length, the cutting machines on both sides come into contact; when the driven telescopic blocks on both sides shorten to the minimum length, the cutting machines do not interfere with the clamping of the pipe.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The sliding of the slider in the chute drives the movement of the driven block, and the synchronous movement of the trapezoidal block thereon enables the second roller on the swing arm to rotate on the outer wall of the trapezoidal block, driving the swing arm to rotate on the connecting rod, thereby adjusting the space between the third rollers and the first roller on both sides, so as to fix pipes with different diameters and reduce the limitations of the device.

[0014] 2. According to the required length of the pipe, the threaded rods on both sides rotate, causing the driven telescopic blocks on both sides to move to the cutting position and be symmetrical to each other. Then they extend to make the cutting machines cut the fixed pipe. Until the driven telescopic blocks retract when they extend to the maximum length, and at the same time, the driven telescopic blocks on the opposite side extend. After cutting the pipe, they retract, so as to cut the pipe to the required length and avoid the need for secondary cutting. Description of the Drawings

Specific Embodiments

[0019] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the following further elaborates the utility model in combination with specific embodiments.

[0020] Such as Figures 1-3As shown in the figure, a clamping and cutting device for building pipes includes a processing block 1. A receiving groove 2 is formed on the top surface of the processing block 1. Symmetric vertical blocks 3 are fixed to the inner bottom of the receiving groove 2. A sliding groove 4 is formed on the side wall of the symmetric vertical blocks 3. A slider 5 is slidably connected in the sliding groove 4. A driven block 6 is fixed between the two sliders 5. A trapezoidal block 7 is fixed to the top end of the driven block 6. A vertical rod 8 is fixed to the top surface of the trapezoidal block 7. Limiting blocks 9 are provided at both ends of the vertical rod 8. A first roller 10 is rotatably connected to the vertical rod 8. Connecting rods 11 are fixedly connected to the inner wall of the receiving groove 2 on both sides of the vertical rod 8. A swing arm 12 is rotatably connected to the connecting rod 11. The side wall of the swing arm 12 contacts the limiting block 9. When the trapezoidal block 7 moves, the hypotenuse will generate a corresponding force on the swing arm 12, causing the second roller 13 to roll on it. At the same time, the swing arm 12 rotates on the connecting rod 11.

[0021] In this embodiment, a second roller 13 is rotatably connected to the end of the swing arm 12. The second roller 13 contacts the outer wall of the trapezoidal block 7. A third roller 14 is rotatably connected to the other end of the swing arm 12. When the swing arm 12 swings, the space between the two third rollers 14 and the first roller 10 will change, so that pipes of different diameters can be accommodated, avoiding the problem of large limitations in only being able to fix a single diameter in the traditional way.

[0022] In this embodiment, fixing blocks 15 are fixed to both ends of the top surface of the processing block 1. An adjusting groove 16 is formed on the fixing block 15. A threaded rod 17 is rotatably connected to the inner walls on both sides of the adjusting groove 16. A driven telescopic block 18 is threadedly connected to the threaded rod 17. A cutting machine 19 is fixedly connected to the end of the driven telescopic block 18. When the threaded rod 17 rotates, the driven telescopic block 18 moves on it, so that the cutting position can be adjusted according to the required length, avoiding the need for secondary cutting later.

[0023] In this embodiment, when the two driven telescopic blocks 18 extend to the maximum length, the two cutting machines 19 contact each other, thereby avoiding the problem of being unable to completely cut the pipe. When the two driven telescopic blocks 18 are shortened to the minimum length, the cutting machines 19 do not interfere with the clamping of the pipe.

[0024] It should be noted that the present utility model is a clamping and cutting device for building pipes. When in use, the slider 5 slides in the chute 4 to drive the driven block 6 to move, and the trapezoidal block 7 thereon moves synchronously, so that the second roller 13 on the swing arm 12 rotates on the outer wall of the trapezoidal block 7, driving the swing arm 12 to rotate on the connecting rod 11, and the space between the third rollers 14 on both sides and the first roller 10 can be adjusted, thereby fixing pipes of different diameters and reducing the limitations of the device. According to the required length of the pipe, the threaded rods 17 on both sides rotate, so that the driven telescopic blocks 18 on both sides move to the cutting position and are symmetric with each other, and then extend to enable the cutting machine 19 to cut the fixed pipe. When the extension reaches the maximum length, the driven telescopic block 18 retracts, and at the same time, the driven telescopic block 18 on the opposite side extends, cuts the pipe and then retracts, thereby realizing cutting the pipe to the required length and avoiding the need for secondary cutting.

[0025] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
