Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically a metal structure pipe cutting saw. Background Technology

[0002] A horizontal band saw is a mechanical device used for cutting materials, widely used in the metal processing industry. Horizontal band saws are suitable for horizontal cutting of large materials, making them very common in the cutting of metal structures and pipes. When a horizontal band saw is working, the transmission system drives the saw blade. Several stacked metal pipes are simultaneously fed from back to front through the feeding mechanism. The metal pipes are clamped by a pressure plate above them, as well as rear fixed blocks and rear sliding blocks on both sides. Then, the lifting head drives the rotating saw blade downwards to cut the metal pipe.

[0003] However, most horizontal band saws on the market currently only fix the metal tubes behind the saw blade. The metal tubes being cut and those cut on the front of the saw blade are generally not fixed. When several stacked metal tubes are cut from top to bottom, the metal tubes cut at the top are instantly unrestrained and are prone to displacement due to vibration and friction with the saw blade, resulting in collisions with the saw blade, increasing saw blade wear, and affecting service life. At the same time, the bouncing caused by the collision between the cut metal tubes and the saw blade also poses a safety hazard, which is not conducive to safe and efficient production for enterprises and urgently needs improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a metal structure pipe cutting saw, which solves the problems of existing horizontal band saws that do not have a fixing function for the metal pipe on the front of the saw blade, resulting in increased saw blade wear and safety hazards caused by the bouncing of the cut metal pipe.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A metal structure pipe cutting saw includes a base, a lifting head mounted on the base, and a saw blade mounted below the lifting head. A support plate for supporting a metal pipe is fixed on the base below the saw blade. A rear fixing block is fixed on one side of the metal pipe on the support plate. A rear sliding block located on the back of the saw blade is slidably connected to the other side of the metal pipe on the support plate. A rear clamping push rod for driving the rear sliding block is fixedly installed on the support plate. A rear fixing frame is horizontally fixed on the rear fixing block. The rear sliding block is slidably connected to the bottom of the rear fixing frame. The rear fixing block, the rear sliding block, the rear clamping push rod, and the rear fixing frame are all located on the back of the saw blade.

[0007] The support plate is provided with a front fixed block, a front sliding block, a front clamping push rod, and a front fixed frame, respectively, corresponding to the rear fixed block, the rear sliding block, the rear clamping push rod, and the rear fixed frame, located on the front of the saw blade. A support frame located above the saw blade is fixed on the rear fixed frame and the front fixed frame. A downward push rod is fixedly installed on the support frame. An arched frame located above the outside of the saw blade is provided below the support frame. The arched frame is fixedly connected to the bottom end of the piston rod of the downward push rod. Pressure plates located above the metal tube are fixed on both the front and back of the bottom of the arched frame.

[0008] Preferably, a clearance groove is provided on the support plate at the position corresponding to the saw blade.

[0009] Preferably, the rear fixed block, rear sliding block, rear clamping push rod, and rear fixed frame are symmetrically arranged with the front fixed block, front sliding block, front clamping push rod, and front fixed frame about the saw blade as the axis of symmetry.

[0010] Preferably, the downward push rod is located directly above the position between the front fixed frame and the rear fixed frame.

[0011] Preferably, the pressure plate is arranged laterally, and two pressure plates are symmetrically arranged on the front and back of the saw blade.

[0012] Preferably, both the support frame and the arched frame are symmetrical structures.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention clamps and fixes the metal tube at two locations on the front and back of the saw blade during cutting, preventing the metal tube from shifting or bouncing during the cutting process, eliminating safety hazards, avoiding additional wear on the saw blade, and extending its service life. It solves the problems of existing horizontal band saws that do not have a fixing function for the metal tube on the front of the saw blade, which leads to increased saw blade wear and safety hazards caused by the bouncing of the cut metal tube.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] like Figs. 1-3 As shown, this utility model provides a technical solution: a metal structure pipe cutting saw, including a base 1, a lifting head 2 installed on the base 1 and a saw blade 3 installed below the lifting head 2. A support plate 5 for supporting a metal pipe 4 is fixed on the base 1 below the saw blade 3, and a clearance groove 501 is provided on the support plate 5 at the position corresponding to the saw blade 3.

[0023] A rear fixing block 6 is fixed on one side of the metal tube 4 on the support plate 5. A rear sliding block 7 located on the back of the saw blade 3 is slidably connected on the other side of the metal tube 4 on the support plate 5. A rear clamping push rod 8 that drives the rear sliding block 7 is fixedly installed on the support plate 5. A rear fixing frame 9 is horizontally fixed on the rear fixing block 6. The rear sliding block 7 is slidably connected to the bottom of the rear fixing frame 9. The rear fixing block 6, the rear sliding block 7, the rear clamping push rod 8 and the rear fixing frame 9 are all located on the back of the saw blade 3.

[0024] On the support plate 5, at the position on the front of the saw blade 3, there are front fixed blocks 10, front sliding blocks 11, front clamping push rods 12 and front fixed frames 13, which correspond to the rear fixed blocks 6, rear sliding blocks 7, rear clamping push rods 8 and rear fixed frames 9, respectively. The rear fixed blocks 6, rear sliding blocks 7, rear clamping push rods 8 and rear fixed frames 9 are symmetrically arranged with the front fixed blocks 10, front sliding blocks 11, front clamping push rods 12 and front fixed frames 13 about the saw blade 3 as the axis of symmetry.

[0025] A support frame 14 is fixed on the rear fixed frame 9 and the front fixed frame 13, located above the saw blade 3. A downward push rod 15 is fixedly installed on the support frame 14. The downward push rod 15 is located directly above the position between the front fixed frame 13 and the rear fixed frame 9. An arched frame 16 is set below the support frame 14, located above the outside of the saw blade 3. The arched frame 16 is fixedly connected to the bottom end of the piston rod of the downward push rod 15. Both the support frame 14 and the arched frame 16 are symmetrical structures. A pressure plate 17 is fixed on the front and back of the bottom of the arched frame 16, located above the metal tube 4. The pressure plate 17 is arranged horizontally, and the two pressure plates 17 are symmetrically arranged on the front and back of the saw blade 3.

[0026] Working principle:

[0027] The metal tube 4 is fed from back to front along the upper surface of the support plate 5. The rear clamping push rod 8 and the front clamping push rod 12 push the rear sliding block 7 and the front sliding block 11 to the right, respectively, and clamp the metal tube 4 from both sides with the rear fixed block 6 and the front fixed block 10. The downward push rod 15 pushes the two pressure plates 17 downward through the arched frame 16 to press the metal tube 4. The rear fixed block 6, the rear sliding block 7, the rear clamping push rod 8 and the rear fixed frame 9 are symmetrically arranged with the front fixed block 10, the front sliding block 11, the front clamping push rod 12 and the front fixed frame 13 with the saw blade 3 as the axis of symmetry. This allows the metal tube 4 to be clamped and fixed at both the front and back of the saw blade 3 when the saw blade 3 is cutting. This prevents the metal tube 4 that is cut in front of the saw blade 3 from shifting or bouncing during the cutting process.
