It can improve cutting efficiency and quality while reducing the labor intensity of operators. This device usually includes components such as a cutting table, a positioning mechanism, a cutting machine and an abutment plate.
[0003] During the cutting process of the elevator guide rail main and auxiliary rail synchronous cutting device, the material will undergo plastic deformation, that is, the material will undergo permanent deformation under the action of shear force. This deformation requires energy, and this energy is manifested in the form of heat, causing the temperature of the cutting area to rise. Due to the high-speed rotation of the blade, the cutting point repeatedly contacts the blade in a very short time, so that the heat has no time to dissipate, resulting in heat accumulation in the cutting area and temperature increase. The heat generated when the high-speed rotating cutting tool contacts the material will cause the material to partially melt or burn, thereby forming smoke and dust. The smoke and dust will reduce visibility in the workplace, affect the operator's line of sight, increase the risk of accidents, and also pollute the working environment. Therefore, in response to the above problems, a elevator guide rail main and auxiliary rail synchronous cutting device is proposed. Utility Model Content

[0023] See also Figure 1-5 , the utility model provides a technical solution:
[0024] A synchronous cutting device for elevator guide rails, main and auxiliary rails, includes a cutting table 1, a positioning mechanism 2, and a transmission channel 3.

[0025] As a further implementation scheme of the above technical solution: by setting the electric telescopic rod 64, there are several electric telescopic rods 64, the electric telescopic rods 64 are arranged in an arc shape, the electric telescopic rods 64 are symmetrically arranged, the other end of the electric telescopic rod 64 is fixedly connected to one side of the protective baffle 66, and the electric telescopic rods 64 are parallel to each other. By adjusting the position and angle of the protective baffle 66, the electric telescopic rod 64 can make the dust suction hole 663 on the protective baffle 66 closer to the cutting area, thereby shortening the distance for smoke and dust to reach the dust suction hole 663, and improving the dust suction efficiency;
[0026] As a further implementation scheme of the above technical solution: a hose 65 is provided, and a plurality of hoses 65 are provided. Both ends of the hose 65 are fixedly connected to the upper end of the dust box 61 and the outer side of the protective baffle 66. The hose 65 is arranged in an arc shape. The hose 65 and the electric telescopic rod 64 are parallel to each other. The hose 65 is evenly and equidistantly arranged between the dust box 61 and the protective baffle 66. The arrangement of the hose 65 can flexibly connect the dust box 61 and the protective baffle 66. The smoke and dust inhaled at various positions of the protective baffle 66 can evenly enter the dust box 61 through the hose 65, avoiding the situation where the dust collection effect is poor in some areas.
[0027] As a further implementation scheme of the above technical solution: by providing a protective baffle 66 and a fixed shaft 5, two protective baffles 66 and fixed shaft 5 are provided, and the protective baffles 66 and fixed shaft 5 are symmetrically arranged on both sides of the cutting table 1, the protective baffles 66 and the fixed shaft 5 are parallel to each other, and one end of the protective baffle 66 is rotatably connected to the outside of the fixed shaft 5.

[0030] As a further implementation plan of the above technical solution: by setting up a motor 62 and a fan 63, there are several motors 62 and fans 63, and the motors 62 and fans 63 are evenly and equidistantly arranged on one side of the dust box 61. A part of the fan 63 is arranged on the inner side of the dust box 61 with a filtering device and a filtering function. Multiple motors 62 and fans 63 are evenly and equidistantly arranged on one side of the dust box 61, which can make the negative pressure distribution in the dust box 61 more uniform, ensuring that the smoke and dust inhaled from various positions of the protective baffle 66 can enter the dust box 61 at the same speed and efficiency.
[0031] Working process: Place the elevator guide rail main and auxiliary rails on the conveying channel 3 set on the cutting table 1, fix the guide rail main and auxiliary rails through the positioning mechanism 2 to ensure that the guide rail main and auxiliary rails will not move during the cutting process, energize through the external wire, start the cutting device 4, and cut the elevator guide rail main and auxiliary rails. During the cutting process, the high-speed rotating cutting tool contacts the guide rail main and auxiliary rail materials to generate heat, smoke and dust, and the dust collection devices 6 on both sides start working. The motor 62 drives the fan 63 to rotate, and negative pressure is generated in the dust box 61. Due to the negative pressure in the dust box 61, the air carries the smoke and dust through the dust collection holes 663 on the protective baffle 66. The air entering the empty bin 662 can more comprehensively absorb smoke and dust from different directions. The arc-shaped protective baffle 66 can effectively control the generation and diffusion of smoke and dust, and improve the quality of the working environment. The air carrying smoke and dust enters the dust box 61 from the empty bin 662 through the hose 65, and the filtered clean air is discharged from the dust box 61, while impurities such as smoke and dust are collected in the dust box 61. According to the size of the main and auxiliary rails of the guide rail and the cutting position, the electric telescopic rod 64 can adjust the position and angle of the protective baffle 66. Under the action of the electric telescopic rod 64, the arc-shaped protective baffle 66 can better cover the cutting area to prevent the spread of smoke and dust.
