Description

Technical Field

[0001] The utility model relates to the technical field of building material processing, in particular to a building material cutting device. Background Art

[0002] In the construction industry, cutting building materials is not only a critical step in the construction process but also fundamental to ensuring building quality and improving construction efficiency. Faced with a diverse range of building materials, such as wood, plastic, lightweight steel keels, and even new composite materials, each material has different physical properties, weight, hardness, and toughness. These varying characteristics lead to different cutting requirements, which presents numerous challenges.

[0003] In particular, some lightweight building materials, such as thin sheets, lightweight alloys, or specialized plastics, are particularly susceptible to external forces, causing them to shift or wobble during the cutting process. This instability can not only cause the cutting path to deviate from the preset trajectory, leading to dimensional deviations and shape distortion, but can also damage cutting tools, increasing repair costs and time. Therefore, effective clamping measures are particularly important before cutting these lightweight building materials. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a building material cutting device, which can effectively solve the problem in the prior art that when cutting building materials, the cutting effect is poor and the cutting efficiency is affected due to the light weight of the building materials.

[0008] According to the above-mentioned building material cutting device, the top end of the screw is fixedly connected with a nut, and the outer side of the nut is made of silicone material.

[0009] According to the above-mentioned building material cutting device, the top end of the sliding column slides through the top plate and is fixedly connected to a limiting ring, and the size of the limiting ring is larger than that of the sliding column.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Refer to Figures 1 to 4A building material cutting device includes a fixed base 1, which is □-shaped. A cylinder 2 is fixedly installed on the top of the fixed base 1. The telescopic end of the cylinder 2 slides through the top wall of the fixed base 1 and is fixedly installed with a mounting frame 3. A mounting column 4 is rotatably installed on the relative inner side of the mounting frame 3. A plurality of cutting blades 5 are fixedly installed on the outer side of the mounting column 4. A limiting mechanism is jointly provided between the mounting column 4 and the mounting frame 3. Two top plates 10 are symmetrically fixedly installed on the top of both ends of the mounting frame 3. The bottom of the top plate 10 slides The main pressure plate 11 is dynamically installed. The top of the main pressure plate 11 is provided with a placement groove 16 adapted to the top plate 10. Two slave pressure plates 12 are fixedly installed between the two main pressure plates 11. The two ends of the top plate 10 are symmetrically slidably connected with the sliding column 13. The top of the sliding column 13 slides through the top plate 10 and is fixedly connected to the limit ring 15. The size of the limit ring 15 is larger than that of the sliding column 13. The bottom end of the sliding column 13 is fixedly connected to the main pressure plate 11. The outer side of the sliding column 13 is provided with a spring 14. The bottom end of the spring 14 It is fixedly connected to the main pressure plate 11, the top of the spring 14 is fixedly connected to the top plate 10, and the bottom of the main pressure plate 11 and the slave pressure plate 12 are fixedly installed with anti-slip pads 17, and the anti-slip pads 17 are made of silicone material; when cutting building materials, the material to be cut is placed on the inner bottom wall of the fixed seat 1, and the mounting frame 3 is driven downward by the cylinder 2. When the mounting frame 3 moves downward, the main pressure plate 11 and the slave pressure plate 12 are first pressed on the material, and the anti-slip pads 17 on the bottom sides of the main pressure plate 11 and the slave pressure plate 12 increase the distance between them and the material to be cut. The friction between them makes the cutting of the material more stable. As the mounting frame 3 continues to move downward, the spring 14 is compressed, and relative sliding occurs between the sliding column 13 and the top plate 10 until the top plate 10 is pressed into the placement groove 16. As the top plate 10 is pressed into the placement groove 16, the cutting blade 5 completes the cutting of the material. The limiting mechanism is used to limit the mounting column 4 and the cutting blade 5. When the cutting blade 5 needs to be replaced, the limit on the mounting column 4 is released, and the cutting blade 5 can be replaced by rotating the mounting column 4.

[0023] The limiting mechanism includes a connecting column 6 rotatably installed on the outside of the mounting frame 3, and the connecting column 6 rotates at one end close to the mounting frame 3 to penetrate the side wall of the mounting frame 3 and is fixedly connected to the mounting column 4. A support plate 7 is fixedly installed on the side wall of the mounting frame 3 close to the connecting column 6, and a screw 8 is threadedly connected to the support plate 7. The top of the screw 8 is fixedly connected to a nut 81. The outer side of the nut 81 is made of silicone material, and two limiting holes 9 are provided on the connecting column 6 that are perpendicular to each other and penetrate the connecting column 6; when the cutting blade 5 cuts the material, the screw 8 is rotated by the nut 81 to insert the bottom end of the screw 8 into the corresponding limiting hole 9, and then the mounting column 4 and the cutting blade 5 are limited by the connecting column 6 to prevent the cutting blade 5 from shaking when cutting the material.

[0024] The working principle of this utility model is as follows:

[0025] When cutting building materials, the material to be cut is placed on the inner bottom wall of the fixing seat 1, and the mounting frame 3 is driven downward by the cylinder 2. When the mounting frame 3 moves downward, the main pressure plate 11 and the slave pressure plate 12 are pressed on the material first, and the anti-slip pads 17 on the bottom sides of the main pressure plate 11 and the slave pressure plate 12 increase the friction between them and the material to be cut, making the cutting of the material more stable. As the mounting frame 3 continues to move downward, the spring 14 is compressed, and relative sliding occurs between the sliding column 13 and the top plate 10 until the top plate 10 is pressed into the placement groove 16, and the cutting blade 5 also completes the cutting of the material. When cutting, the nut 81 rotates the screw rod 8 to insert the bottom end of the screw rod 8 into the corresponding limiting hole 9, and then limits the mounting column 4 and the cutting blade 5 through the connecting column 6 to prevent the cutting blade 5 from shaking when cutting the material. When the cutting blade 5 needs to be replaced, the limit on the mounting column 4 is released, and the cutting blade 5 can be replaced by rotating the mounting column 4. When the mounting frame 3 and the cutting blade 5 are driven downward by the cylinder 2, under the action of the top plate 10, the main pressure plate 11 and the slave pressure plate 12, the edge of the building material is first pressed and then cut, which not only has a better cutting effect and improves the cutting efficiency, but also reduces the possibility of blade wear.
