Description

Technical Field

[0001] This utility model relates to the field of metal band saw technology, and more specifically, to a metal band saw with a protective structure. Background Technology

[0002] A metal band saw is a machine tool used for cutting various metal materials, primarily low-alloy steel, high-alloy steel, special alloy steel, and stainless steel. It boasts high efficiency and precision cutting capabilities and is widely used in manufacturing, construction, and maintenance industries. A metal band saw mainly consists of a bed, worktable, saw blade, and transmission system. The bed forms the foundation of the machine, bearing the load during the cutting process. The worktable supports the metal material and is adjustable in height and angle to meet different cutting needs. The saw blade is the cutting tool, driven by the transmission system to rotate and achieve the cutting action. However, existing metal band saws lack safety features, and the saw blade may break during use, posing a danger to workers nearby. Therefore, we propose a metal band saw with a protective structure.

[0025] Please see Figure 1-5 A metal band saw with a protective structure includes a base 1, mounting seats 2 on both sides of the base 1, hydraulic cylinders 3 fixedly mounted on the two mounting seats 2, band saw blade cutter 4 fixedly connected to the top of the two hydraulic cylinders 3, lifting mechanism 5 on the side of the band saw blade cutter 4, lifting seat 6 on the lifting mechanism 5, protective shell 7 fixedly connected to the bottom surface of the lifting seat 6, protective shell 7 being fitted over the outside of the band saw blade cutter 4, observation ports 8 on the front and rear of the protective shell 7, observation mechanisms 9 in the inner cavity of the two observation ports 8, two fixing mechanisms 11 on the two observation mechanisms 9, and two insertion seats 10 fixedly connected to the front and rear of the protective shell 7.

[0026] For details, please refer to Figures 1 to 3 The lifting mechanism 5 includes lifting frames 12 fixedly connected to both sides of the band saw blade cutting machine 4. Lifting grooves 13 are provided on the inner sides of the two lifting frames 12. Screws 14 are rotatably connected to the inner cavities of the two lifting grooves 13 respectively. Lifting seats 6 are threaded onto the two screws 14. The side of the lifting seats 6 is in contact with the inner wall of the lifting grooves 13.

The output shaft of the servo motor 15 is connected to the bottom end of one screw 14.

[0027] In this embodiment, the inner wall of the lifting groove 13 is used to limit the lifting seat 6, so that the lifting seat 6 and the protective shell 7 can only move up and down along the axial direction of the screw 14.

[0028] For details, please refer to Figures 1 to 4The observation mechanism 9 includes two hovering hinges 18 fixedly installed on the outside of the protective shell 7 and on the upper part of the observation port 8. A glass door 19 is fixedly installed at the bottom of the two hovering hinges 18. The glass door 19 is located in the inner cavity of the observation port 8. The two sides of the glass door 19 are respectively attached to the inner wall of the observation port 8. A support base 20 is fixedly connected to the inner side of the glass door 19. Multiple gas rods 21 are fixedly installed on the bottom surface of the support base 20. Telescopic glass plates 22 are fixedly connected to the bottom ends of the multiple gas rods 21 respectively.

[0029] In this embodiment, both the glass door 19 and the telescopic glass panel 22 are made of high-strength glass to prevent damage from impacts. At the same time, the cutting of materials by the band saw blade cutter 4 can be controlled through the glass door 19 and the telescopic glass panel 22. In addition, when the glass door 19 and the telescopic glass panel 22 move down with the band saw blade cutter 4, the telescopic glass panel 22 moves up due to the obstruction of the cutting material, ensuring that the telescopic glass panel 22, the glass door 19 and the protective shell 7 can effectively block and protect the outside of the band saw blade cutter 4.

[0030] For details, please refer to Figure 1 , Figure 3 and Figure 5 The fixing mechanism 11 includes a telescopic shell 25 fixedly connected to the outside of the glass door 19. A spring 26 is fixedly connected to the inner wall of the telescopic shell 25. A plug 27 is fixedly connected to the end of the spring 26. One end of the plug 27 extends to the outside of the telescopic shell 25 and is movably sleeved into the inner cavity of the socket seat 10. A pull rod 28 is fixedly connected to the other end of the plug 27. The end of the pull rod 28 is movably sleeved into the outside of the telescopic shell 25 and is fixedly connected to a pull block 29. The sides of the plug 27 are respectively attached to the inner walls of the telescopic shell 25 and the socket seat 10.

[0031] In this embodiment, the spring force of the spring 26 drives the plug 27 to be inserted into the socket 10, and the glass door 19 is fixed in the inner cavity of the observation port 8 by the cooperation of the plug 27, the telescopic shell 25 and the socket 10.

[0032] For details, please refer to Figure 1 A control panel 24 is fixedly mounted on the front of the base 1.

[0033] In this embodiment, the device is controlled using the control panel 24.

[0034] For details, please refer to Figure 1 and Figure 2 A handle 23 is fixedly installed on the outside of the glass door 19.

[0035] In this embodiment, the handle 23 is used to open the glass door 19.

[0036] Working Principle: In operation, firstly, hydraulic cylinder 3 is activated to move band saw blade cutter 4 upwards, placing the material to be cut onto machine base 1, ensuring the material is positioned below the saw blade on band saw blade cutter 4. Then, hydraulic cylinder 3 moves band saw blade cutter 4 downwards, bringing the saw blade into contact with the top of the material. Servo motor 15 is then activated, driving one screw 14 and one synchronous pulley 16 to rotate. Through the transmission between the two synchronous pulleys 16 and synchronous belt 17, another screw 14 rotates. The threaded engagement between the two screws 14 and lifting base 6 causes the protective shell 7 to move downwards, making the bottom surface of the protective shell 7 flush with the bottom surface of band saw blade cutter 4. Finally... The saw blade on the band saw blade cutter 4 rotates, and the hydraulic cylinder 3 is activated to move the band saw blade cutter 4 downwards, using the saw blade to cut the material. In addition, as the band saw blade cutter 4 moves downwards, the protective shell 7, glass door 19 and telescopic glass plate 22 move downwards simultaneously. The bottom end of the telescopic glass plate 22 is pushed upwards by the top of the material, and at the same time, the air rod 21 retracts, ensuring the integrity of the protective shell 7, glass door 19 and telescopic glass plate 22 in protecting the outside of the hydraulic cylinder 3. When the saw blade on the band saw blade cutter 4 breaks, the protective shell 7, glass door 19 and telescopic glass plate 22 are used to block the saw blade and prevent the broken saw blade from flying.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
