Description

Technical Field

[0001] This utility model relates to the field of brick cutting technology, specifically to a refractory brick cutting machine. Background Technology

[0002] In modern construction and industrial fields, refractory bricks are widely used in high-temperature environments such as furnaces, boilers, ceramics, and glass due to their excellent high-temperature resistance, corrosion resistance, and superior mechanical strength. After firing, cast or partially pressed products still need to be further processed to meet the requirements of use. For example, large blanks of electrofused refractory materials, master bricks of composite bricks, and some irregular products all need to be cut into blocks or shaped.

[0003] Currently, refractory brick cutting is mostly done using handheld cutting machines or simple tabletop cutting equipment. However, these methods generally present the following problems: First, safety is insufficient. Operators typically need to hold the refractory brick directly close to the high-speed rotating cutting blade. Due to the hardness of the refractory brick, it is prone to vibration or deviation during cutting, easily leading to contact between the operator's hand and the cutting blade, causing serious accidents. Second, cutting accuracy is difficult to guarantee. The manual pushing method lacks stability, easily causing the cutting path to deviate from the intended line, resulting in brick waste. Especially when batch cutting of the same size refractory bricks is required, the lack of effective limiting references makes it difficult to ensure consistent cutting dimensions for each brick. Furthermore, during cutting, the interaction force between the cutting blade and the refractory brick can easily cause displacement, jumping, or even breakage. This not only affects the flatness of the cut surface, but the flying fragments also pose a safety threat to the operator. Therefore, a device is needed to solve these problems.

The upper surface of the table is provided with multiple replacement seats. The upper surface of the replacement seats is provided with multiple rollers to reduce the friction between the refractory brick and the table.

[0006] Optionally, the guiding mechanism includes a slide groove and a slider. The slide groove is formed on both sides of the upper surface of the table along the length direction of the table.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 5 This utility model provides a technical solution: a refractory brick cutting machine, including a table 1 and a cutting blade 2 disposed in the middle of the upper surface of the table 1. A drive motor is provided on the lower surface of the table 1 to drive the cutting blade 2 to rotate. A push plate 3 is slidably connected to the upper surface of the table 1 through a guide mechanism.

[0018] A positioning mechanism is provided on one side of the push plate 3 to determine the placement position of the refractory brick. An extension rod 4 is fixedly connected to the other side of the push plate 3. A pressure plate 5 is provided on the side of the extension rod 4 facing the cutting blade 2 to restrict the refractory brick from being lifted. Multiple replacement seats 16 are provided on the upper surface of the table 1. Multiple rollers 17 are provided on the upper surface of the replacement seats 16 to reduce the friction between the refractory brick and the table 1.

[0019] The refractory brick is placed on the table 1, and the pusher plate 3 is pushed to the side of the cutting blade 2, so that the cutting blade 2 cuts the refractory brick. The guide mechanism constrains the movement direction of the pusher plate 3, so that the pusher plate 3 can only move vertically towards the cutting blade 2, which improves the stability of the pusher plate 3 during the movement process. The positioning mechanism positions the end of the refractory brick to ensure that each refractory brick is placed in the same position, so as to achieve the effect of cutting the same batch of refractory bricks to the same size. The pressure plate 5 constrains the upper surface of the refractory brick, preventing the refractory brick from being lifted accidentally during the cutting process, and can also press the refractory brick to reduce the shaking of the refractory brick during the movement. After the cutting is completed, the refractory brick will move to the roller 17. The refractory brick behind will continuously push the refractory brick in front to move. The roller 17 reduces the resistance of the refractory brick movement. Baffles can also be installed on both sides of the cutting blade 2 to prevent the cut refractory brick from continuously colliding with the cutting blade 2.

[0020] In this embodiment, as a preferred solution, the guiding mechanism includes a slide 6 and a slider 7. The slide 6 is opened on both sides of the upper surface of the table 1 along the length direction of the table 1. The slider 7 is fixedly connected to the lower surface of the push plate 3 and is guided and slidably connected to the slide 6. The side wall of the table 1 is provided with a chip removal hole 8, which is connected to the inner wall of the slide 6 to discharge the debris in the slide 6.

[0021] The slide 6 is inverted T-shaped. The slider 7 can slide along the slide 6. If the chips and dust that fall during the cutting process fall into the slide 6, they will be continuously pushed towards both ends of the slide 6 by the slider 7 as it moves. The two ends of the slide 6 are provided with chip discharge holes 8, which will push out the chips inside during the sliding process to prevent the slider 7 from getting stuck and unable to slide.

[0022] In this embodiment, as a preferred solution, the positioning mechanism includes a positioning plate 9 and an adjusting bolt 10. The positioning plate 9 is guided and slidably disposed on one side of the push plate 3. The adjusting bolt 10 is threadedly connected to the upper surface of the positioning plate 9 and its bottom is pressed against the upper surface of the push plate 3. The surface of the push plate 3 is provided with a scale 11 along the sliding direction of the positioning plate 9. The end of the positioning plate 9 is provided with an inclination angle toward the scale 11 to view the current position. A friction pad 12 is fixedly connected to the upper surface of the push plate 3. The lower surface of the adjusting bolt 10 is in contact with and pressed against the upper surface of the friction pad 12.

[0023] Tightening the adjusting bolt 10 fixes the position of the positioning plate 9, preventing it from shaking. The tilt angle of the end of the positioning plate 9 faces the scale 11. By checking the scale 11, the current position of the positioning plate 9 can be determined, allowing for precise adjustment. After the positioning plate 9 is fixed, one end of the refractory brick is attached to the positioning plate 9, and the other end is attached to the push plate 3. At the same time, ensure that the pressure plate 5 is above the refractory brick. The position of the refractory brick can then be determined, and it can be cut. Ensure that the cutting position of each refractory brick is the same. The friction pad 12 increases the friction between the adjusting bolt 10 and the push plate 3, further reducing the shaking of the positioning plate 9.

[0024] In this embodiment, as a preferred option, a vertical guide groove 13 is provided on one side of the extension rod 4. A fixing bolt 14 is slidably connected to the inner wall of the guide groove 13. One end of the fixing bolt 14 is threadedly connected to the pressure plate 5 to fix the height of the pressure plate 5.

[0025] The pressure plate 5 and the fixing bolt 14 can slide up and down in the guide groove 13. The height of the pressure plate 5 can be adjusted according to the height of the current batch of refractory bricks, so that there is a certain gap between the height of the pressure plate 5 and the refractory bricks. This ensures that the refractory bricks cannot be lifted, while also allowing the refractory bricks to be inserted from one side under the pressure plate 5, thereby improving production efficiency and avoiding the need to use the pressure plate 5 for fixing each time.

[0026] In this embodiment, as a preferred option, the push plate 3 is provided with a clearance groove 15 at the position corresponding to the cutting blade 2 to avoid the cutting blade 2.

[0027] The clearance groove 15 is V-shaped. When the push plate 3 is pushed to one side of the cutting blade 2, the clearance groove 15 can avoid the cutting blade 2 to prevent the cutting blade 2 from cutting the push plate 3 itself.

[0028] In this invention, the working steps of the device are as follows: 1. Based on the height of the current batch of refractory bricks and the position to be cut, adjust the pressure plate 5 to a position slightly higher than the refractory bricks, then tighten the fixing bolts 14, adjust the position of the positioning plate 9 according to the position to be cut, and use the adjusting bolts 10 to fix the position of the positioning plate 9. 2. After the positioning plate 9 and the pressure plate 5 are fixed, pull the push plate 3 towards the end of the table 1, place the refractory brick on the table 1, align the two sides of the refractory brick with the positioning plate 9 and the push plate 3 respectively, and ensure that the refractory brick is under the pressure plate 5. 3. After placing the refractory bricks, hold the handle on the back of the push plate 3 and push the push plate 3 towards the cutting blade 2 so that the cutting blade 2 cuts the refractory bricks. After cutting, the cut refractory bricks will remain on both sides of the cutting blade 2. Then reset the push plate 3 and place the new refractory bricks to be cut in place to continue cutting. The cut refractory bricks will continuously push the refractory bricks in front to move.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
