Description

Technical Field

[0001] The utility model relates to the field of power tools, in particular to a steel bar cutting machine with a dust-proof structure. Background Art

[0002] A steel bar cutting machine is a mechanical equipment dedicated to the cutting of steel bars, profiles, angle steels, pipes, cables in construction sites and other infrastructure construction fields. Its main function is to quickly and accurately cut long strip-shaped metal materials such as steel bars according to a predetermined length. This equipment can efficiently process steel bars with different diameters and strengths, including ordinary carbon steel, hot-rolled round steel, deformed steel bars, flat steel, square steel, etc., and is an indispensable tool in the steel bar processing process.

[0003] At present, most of the rechargeable steel bar cutting machines on the market need to set an opening on the overall shield extending to the saw blade part due to the requirements of the cutting function itself; during the actual cutting of steel bars, when the axis of the output shaft is approximately parallel to the ground during the cutting operation of the operator, due to the rotation direction of the saw blade, the chips on one side will always fly out from the opening driven by the saw blade, affecting the operator's cutting and the observation of the cut part. Moreover, if it accidentally flies into the operator's eyes, it will be very dangerous, thus affecting the safety of the operation.

[0004] Therefore, it is necessary to provide a new steel bar cutting machine with a dust-proof structure to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a steel bar cutting machine with a dust-proof structure.

[0006] The steel bar cutting machine with a dust-proof structure provided by the utility model includes a steel bar cutting machine. An opening is arranged at the front side of the steel bar cutting machine. At least two positioning holes are respectively arranged on both sides of the steel bar cutting machine at the opening. A dust-proof gasket is arranged in at least two positioning holes, and the dust-proof gasket extends from the top of the steel bar cutting machine to the opening and forms a gap. The positions of the two dust-proof gaskets at the opening are inclined from the outside to the inside towards the steel bar cutting machine.

[0007] Further, a transmission cavity is formed inside the steel bar cutting machine. The transmission cavity is communicated with the positioning holes, and a dust exhaust port communicated with the transmission cavity is arranged on one side outside the steel bar cutting machine.

[0008] Further, the cross-section of the positioning hole is arranged in a "convex" shape, and a chamfer is arranged at the top of the steel bar cutting machine at the positioning hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1Schematic diagram of the overall structure of the steel bar cutting machine with a dust-proof structure provided by the present utility model; Figure 2 Partial sectional structure schematic diagram of the steel bar cutting machine with a dust-proof structure provided by the present utility model; Figure 3 Exploded structure schematic diagram of the steel bar cutting machine and the dust-proof gasket provided by the present utility model; Figure 4 Structure schematic diagram of the dust-proof gasket provided by the present utility model.

[0021] In the specific implementation process, as Figures 1 to 4 shown, the steel bar cutting machine with a dust-proof structure provided by the present utility model includes a steel bar cutting machine 1. An opening 2 is arranged on the front side of the steel bar cutting machine 1. At least two positioning holes 4 are respectively arranged on both sides of the steel bar cutting machine 1 at the opening 2. A dust-proof gasket 5 is arranged in at least two positioning holes 4. The dust-proof gasket 5 extends from the top of the steel bar cutting machine 1 towards the opening 2 and forms a gap. The positions of the two dust-proof gaskets 5 at the opening 2 are inclined from the outside to the inside towards the steel bar cutting machine 1;

[0022] The steel bar cutting machine 1 is powered by a battery. After being decelerated by a gearbox to a power output shaft, the output shaft drives a slicer. The steel bar moves along the opening towards the direction close to the slicer. The dust-proof gasket is made of rubber material. When the steel bar enters the opening and approaches the slicer, it will deform to enable the steel bar to enter smoothly to achieve the cutting effect;

[0023] By designing the dust-proof gasket 5 at the opening 2, during the working process of the steel bar cutting machine 1, the probability of chips splashing from the opening 2 is greatly reduced. The operator can, while cutting, better observe the cutting position and effect through the gap between the two dust-proof gaskets 5, and the safety of tool use is improved. The structure of the dust-proof gasket 5 is simple, convenient for installation, and convenient for disassembly and replacement after aging.

[0024] A transmission cavity 3 is formed inside the steel bar cutting machine 1. The transmission cavity 3 is communicated with the positioning hole 4. A dust discharge port 10 communicated with the transmission cavity 3 is arranged on one side outside the steel bar cutting machine 1. The cross-section of the positioning hole 4 is in a "convex" shape. A chamfer is arranged at the top of the steel bar cutting machine 1 at the positioning hole 4. Two extension ends 6 are fixedly connected to the bottom of the dust-proof gasket 5. A positioning end 7 is fixedly connected to the bottom of the extension end 6. The radial dimension of the positioning end 7 is larger than that of the extension end 6. A chamfer is arranged at the position of the lower end on the outside of the positioning end 7. A docking ring groove 8 adapted to the steel bar cutting machine 1 is arranged on one of the dust-proof gaskets 5;

[0025] The extension end 6 and the positioning end 7 are made of rubber. When the dust-proof gasket 5 is set on the positioning hole 4 of the steel bar cutting machine 1, the radial dimension of the positioning end 7 is larger than that of the extension end 6. During installation, it passes through the positioning hole 4 of the steel bar cutting machine 1 by elastic deformation, and then the step surface formed by the two different diameters cooperates with the positioning hole 4 of the steel bar cutting machine 1 to form an undercut, fixing the dust-proof gasket 5 on the positioning hole 4.

[0026] Through the setting of the dust discharge port 10, not only can the residual materials brought in during cutting in the transmission cavity 3 be effectively discharged, but also when the extension end 6 and the positioning end 7 of the dust-proof gasket 5 are broken due to loading and unloading errors, they can fall into the transmission cavity 3 and be discharged through the connected dust discharge port 10.

[0027] At the position where the bottom of the dust-proof gasket 5 is located at the opening 2, a flexible fireproof material 9 is also provided. The flexible fireproof material 9 is silicone rubber. Silicone rubber is a high-temperature resistant and flame-retardant elastic material with excellent weather resistance and chemical resistance. It can withstand large temperature changes without losing its physical properties and is suitable for manufacturing dust-proof gaskets that require fireproof performance. Thus, the sparks generated during the processing of the steel bar cutting machine 1 are blocked by the flexible fireproof material 9 to avoid direct contact with the dust-proof gasket 5 and cause a decrease in its lifespan.
