Description

Technical Field

[0001] This invention relates to the field of building block manufacturing technology, specifically a cutting device for processing refractory materials. Background Technology

[0002] Fire-resistant building blocks are manufactured using a beveled cutting process. The core of this process is to adapt to the installation requirements of irregular building nodes (such as wall corners, pipeline perimeters, and irregular holes). Through precise bevel cutting, seamless splicing between blocks is achieved, reducing the risk of fire leakage through gaps. At the same time, it meets the adaptability requirements of different angle fitting and component connection in fire-resistant structures, further improving the overall fireproof sealing and structural stability.

[0003] However, traditional cutting devices mainly adopt a fixed vertical cutting mode, where the cutting tool and the material conveying direction are always at a fixed 90-degree angle, making it impossible to adjust the cutting angle within a certain range. This means that the requirement for oblique cutting often needs to be completed through secondary processing. Furthermore, the single vertical cutting mode forces complex splicing structures to be achieved through multiple processes, and the cutting accuracy is significantly reduced due to the impact of multiple positioning. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting device for processing refractory materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for processing refractory materials, comprising an adjustable cutting assembly, wherein the adjustable cutting assembly includes a mounting base disposed at the end, a slider is slidably limited within a through hole on the side of the mounting base, and a sliding pin is fixedly connected to the inner side of the middle portion of the slider, a V-shaped swing arm is rotatably mounted on the outer side of the end of the slider, and a cutting head driven by a motor is mounted at the end of the long arm of the V-shaped swing arm, a connecting pin is connected to the end of the short arm of the V-shaped swing arm, and the connecting pin is fixedly connected to the end of a telescopic rod, the telescopic rod is fixedly connected to the telescopic end of a cylinder, and the tail of the cylinder is rotatably connected to the mounting base through a tailstock.

[0006] Furthermore, the mounting base is fixedly installed on the top side of the gantry frame, and the gantry frame is fixedly installed on the top middle of the movable plate, and a trunnion is fixedly installed at the rear end of the movable plate.

[0007] Furthermore, a drive rack is rotatably mounted inside the recess of the gantry frame, and a cam column is coaxially fixed in the middle of the drive rack, and the groove on the surface of the cam column slides in cooperation with the sliding pin.

[0008] Furthermore, a sleeve is fixedly installed at the front end of the movable plate, and a pin is axially slidably installed inside the sleeve. A spring is sleeved in the middle of the pin, and the pin is elastically connected to the inner wall of the sleeve cavity through the spring.

[0009] Furthermore, a linkage feeding assembly is provided below the movable plate. The linkage feeding assembly includes a fixed plate located below the movable plate. Bearing seats are fixedly installed at both ends of the top of the fixed plate, and driven gears are rotatably installed inside the bearing seats on both sides.

[0010] Furthermore, the linkage feeding assembly also includes gears coaxially fixed to both ends of the driven rack, a bracket is fixedly installed on the side end of the fixed plate, and a bushing is fixedly installed at the bottom of the bracket, with the outer circle of the bushing rotatingly engaging with the trunnion through hole.

[0011] Furthermore, the linkage feeding assembly also includes a double-headed toothed rod rotatably installed inside the bushing through hole. The bevel teeth at the top of the double-headed toothed rod mesh with the bevel teeth at the end of the driving toothed rod, and the bevel teeth at the bottom of the double-headed toothed rod mesh with the bevel teeth at the end of the driven toothed rod.

[0012] Furthermore, the fixing plate is bolted to the middle of the base, and an angle adjustment plate with an arc-shaped structure is fixedly installed on the side of the base. The angle adjustment plate has partitions fixed at equal intervals along the arc-shaped structure inside, and the gap between adjacent partitions is engaged with the pin.

[0013] Furthermore, end plates are fixedly installed at both ends of the base, and guide rods are fixedly connected to the opposite surfaces of the two end plates.

[0014] Furthermore, a worktable is slidably mounted in the middle of the guide rod, and toothed plates are fixedly mounted at both ends of the bottom of the worktable, with the toothed plates on both sides meshing with the outer teeth of the gear.

[0015] This invention provides a cutting device for processing refractory materials, which has the following beneficial effects; 1. In use, the cutting head of this application only contacts the material during the forward movement and automatically lifts and separates during the return movement. This not only eliminates the scratch damage to the cut during the return movement but also effectively shortens the ineffective stroke and extends the tool life. When the user needs to adjust the cutting angle to achieve oblique cutting, simply pull out the pin and drive the movable plate to rotate around the trunnion as the axis. After re-inserting the pin into the corresponding angle gap, the movable plate can be driven to adjust the cutting angle within the arc range of the angle adjustment plate. This allows the cutting angle to be adjusted within a certain range. The angle of the movable plate can be shifted through simple operation, switching between vertical cutting and oblique cutting to meet the processing requirements of different cutting angles of refractory materials.

[0016] 2. In use, this application achieves adjustable angle cutting by means of the linkage between the adjustable cutting component and the linkage feeding component. With only one cylinder drive, the V-shaped swing arm can be reciprocated to achieve adjustable angle cutting by sliding. At the same time, the linear reciprocating motion of the slider is converted into the intermittent rotational motion of the cam column by the movement of the sliding pin on the side of the slider in the groove on the surface of the cam column. This motion is then converted into the stepping supply motion of the worktable on the guide rod through a series of transmissions. This allows the worktable to automatically carry refractory material for stepping supply after the cutting head completes a single cut, thus achieving continuous cutting. On the other hand, the transmission design of the double-headed rack ensures that the movable plate can maintain the transmission connection with the driven rack even after the offset angle is adjusted. No matter what angle the cutting head cuts at, the worktable can always achieve stepping supply in the same direction. The structural design is reasonable and the linkage is strong.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] Please see Figures 1 to 6The present invention provides a technical solution: a cutting device for processing refractory materials, including an adjustable cutting component 1. The adjustable cutting component 1 includes a mounting base 101 disposed at the end. A slider 102 is slidably limited in a through hole on the side of the mounting base 101. A sliding pin 103 is fixedly connected to the inner side of the middle part of the slider 102. A V-shaped swing arm 104 is rotatably mounted on the outer side of the end of the slider 102. A cutting head 105 driven by a motor is mounted at the end of the long arm of the V-shaped swing arm 104. A connecting pin 106 is connected to the end of the short arm of the V-shaped swing arm 104. The connecting pin 106 is fixedly connected to the end of the telescopic rod 107. The telescopic rod 107 is fixedly connected to the telescopic end of the cylinder 108. The tail of the cylinder 108 is rotatably connected to the mounting base 101 through a tail seat 109. The specific operation is as follows: the refractory material to be cut is placed on the worktable 16. When the vertical cutting mode is adopted, the cutting head 105 is at a 90-degree angle to the refractory material conveying direction. When the piston rod of the cylinder 108 extends, the telescopic rod 107 drives the slider 102 to move forward through the connecting pin 106. At this time, the V-shaped swing arm 104 rotates around the axis on the outer side of the end of the slider 102 and closes, so that the cutting head 105 completes the cutting of the refractory material to be cut at a predetermined angle during the forward movement. When the piston rod of the cylinder 108 retracts, the telescopic rod 107 first drives the V-shaped swing arm 104 to rotate in the opposite direction to open and then drives the slider 102 to retract, so that the cutting head 105 separates from the refractory material to be cut during the retraction process. The above technical solution makes the cutting head 105 only contact the material during the forward movement and automatically lifts and separates during the return movement. This not only eliminates the scratch damage to the cut during the retraction process, but also effectively shortens the ineffective stroke and extends the tool life. Please see Figures 1 to 2 Mounting base 101 is fixedly installed on the top side of gantry frame 2, and gantry frame 2 is fixedly installed on the top middle of movable plate 3. A trunnion 4 is fixedly installed at the rear end of movable plate 3. A drive rack 5 is rotatably installed inside the recess of gantry frame 2. A cam column 6 is coaxially fixed in the middle of drive rack 5. The groove on the surface of cam column 6 is slidably engaged with sliding pin 103. A sleeve 7 is fixedly installed at the front end of movable plate 3. A pin 8 is axially slidably installed inside sleeve 7. A spring 9 is sleeved in the middle of pin 8. Pin 8 is elastically connected to the inner wall of sleeve 7 cavity through spring 9. The specific operation is as follows: when the user needs to adjust the cutting angle to achieve oblique cutting, simply pull out the pin 8 and drive the movable plate 3 to rotate around the trunnion 4 as the axis. After re-inserting the pin 8 into the gap of the partition 13 at the corresponding angle, the movable plate 3 can be driven to adjust the cutting angle within the arc range of the angle adjustment plate 12. This allows the cutting angle of this application to be adjusted within a certain range. The angle of the movable plate 3 can be shifted through simple operation, switching between vertical cutting and oblique cutting to meet the processing requirements of different cutting angles of refractory materials. Please see Figures 3 to 4A linkage feeding assembly 10 is provided below the movable plate 3. The linkage feeding assembly 10 includes a fixed plate 1001 located below the movable plate 3. Bearing seats 1002 are fixedly installed at both ends of the top of the fixed plate 1001, and driven racks 1003 are rotatably installed inside the bearing seats 1002 on both sides. The linkage feeding assembly 10 also includes gears 1004 coaxially fixed to both ends of the driven racks 1003. A bracket 1005 is fixedly installed on the side of the fixed plate 1001, and a bushing 1006 is fixedly installed at the bottom of the bracket 1005. The outer circle of the bushing 1006 rotatably engages with the through hole of the trunnion 4. The linkage feeding assembly 10 also includes a double-headed rack 1007 rotatably installed inside the through hole of the bushing 1006. The top bevel gear of 07 meshes with the bevel gear at the end of the drive rack 5, and the bottom bevel gear of the double-headed rack 1007 meshes with the bevel gear at the end of the driven rack 1003. The fixing plate 1001 is bolted to the middle of the base 11, and an arc-shaped angle adjustment plate 12 is fixedly installed on the side of the base 11. The angle adjustment plate 12 has partitions 13 fixed at equal intervals along the arc structure inside, and the gap between adjacent partitions 13 is engaged with the pin 8. The front and rear ends of the base 11 are fixedly installed with end plates 14, and the opposite surfaces of the two end plates 14 are fixedly connected with guide rods 15. The middle of the guide rod 15 is slidably installed with a worktable 16, and the bottom ends of the worktable 16 are fixedly installed with toothed plates 17, and the two toothed plates 17 mesh with the outer circular teeth of the gear 1004. The specific operation is as follows: Driven by cylinder 108, slider 102 drives the V-shaped swing arm 104 at its end to achieve reciprocating feeding motion. Simultaneously, slider 102 also drives the sliding pin 103 in the middle of its inner side to move within the groove on the surface of cam column 6, converting the linear reciprocating motion of slider 102 into the intermittent rotational motion of cam column 6. This, in turn, drives rack 5 to mesh with double-headed rack 1007, causing driven rack 1003 and its two gears 1004 in the middle to rotate synchronously and intermittently. Finally, under the meshing action of the toothed plates 17 at both ends of the bottom of worktable 16 and gears 1004, the intermittent rotation of gears 1004 drives worktable 16 to move on guide rod 15 to achieve step-feeding. This application, on the one hand, achieves this through the linkage between adjustable cutting assembly 1 and linkage feeding assembly 10, requiring only one cylinder 108 to drive. While the sliding drive of the V-shaped swing arm 104 reciprocates to achieve adjustable angle cutting of the cutting head 105, the linear reciprocating motion of the slider 102 is converted into the intermittent rotational motion of the cam column 6 by the movement of the sliding pin 103 on the side of the slider 102 located in the groove on the surface of the cam column 6. This motion is then converted into the stepping supply motion of the worktable 16 on the guide rod 15 through a series of transmissions. This allows the worktable 16 to automatically carry refractory material for stepping supply after the cutting head 105 completes a single cut, thus achieving continuous cutting. On the other hand, through the transmission design of the double-headed rack 1007, the movable plate 3 can still maintain the transmission connection with the driven rack 1003 after adjusting the offset angle. No matter what angle the cutting head 105 cuts at, the worktable 16 can always achieve stepping supply in the same direction. The structural design is reasonable and the linkage is strong.

[0021] In summary, when using this cutting device for processing refractory materials: First, the refractory material to be cut is placed on the worktable 16. When the vertical cutting mode is adopted, the cutting head 105 is at a 90-degree angle to the refractory material conveying direction. When the piston rod of the cylinder 108 extends, the telescopic rod 107 drives the slider 102 to move forward through the connecting pin 106. At this time, the V-shaped swing arm 104 rotates around the axis on the outer side of the end of the slider 102 and closes, so that the cutting head 105 completes the cutting of the refractory material to be cut at a predetermined angle during the forward movement. When the piston rod of the cylinder 108 retracts, the telescopic rod 107 first drives the V-shaped swing arm 104 to rotate in the opposite direction to open and then drives the slider 102 to retract, so that the cutting head 105 separates from the refractory material to be cut during the retraction process. The above technical solution makes the cutting head 105 only contact the material during the forward movement and automatically lifts and separates during the return movement. This not only eliminates the scratch damage to the cut during the retraction process, but also effectively shortens the ineffective stroke and extends the tool life. Secondly, when the user needs to adjust the cutting angle to achieve oblique cutting, simply pull out the pin 8 and drive the movable plate 3 to rotate around the trunnion 4 as the axis. After re-inserting the pin 8 into the gap of the partition 13 at the corresponding angle, the movable plate 3 can be driven to adjust the cutting angle within the arc range of the angle adjustment plate 12. This allows the application to adjust the cutting angle within a certain range. The angle of the movable plate 3 can be shifted through simple operation, switching between vertical cutting and oblique cutting to meet the processing requirements of different cutting angles of refractory materials. Finally, under the drive of cylinder 108, the slider 102 drives the V-shaped swing arm 104 at the end to achieve feed reciprocating motion. At the same time, the slider 102 also drives the sliding pin 103 in the middle of the inner side to move in the groove on the surface of the cam column 6, converting the linear reciprocating motion of the slider 102 into the intermittent rotational motion of the cam column 6. This drives the rack 5 to mesh with the double-headed rack 1007, driving the driven rack 1003 and the two gears 1004 in the middle to rotate synchronously and intermittently. Finally, under the meshing action of the toothed plates 17 at both ends of the bottom of the worktable 16 and the gears 1004, the intermittent rotation of the gears 1004 drives the worktable 16 to move on the guide rod 15 to achieve step feeding. This application, on the one hand, through the linkage between the adjustable cutting component 1 and the linkage feeding component 10, only one cylinder 108 is needed to drive the slider 102 to achieve feed reciprocating motion. The V-shaped swing arm 104 is driven to reciprocate and feed, enabling the cutting head 105 to cut at an adjustable angle. At the same time, the linear reciprocating motion of the slider 102 is converted into the intermittent rotational motion of the cam column 6 by the movement of the sliding pin 103 on the side of the slider 102 located in the groove on the surface of the cam column 6. This motion is then converted into the stepping supply motion of the worktable 16 located on the guide rod 15 through a series of transmissions. This allows the worktable 16 to automatically carry refractory material for stepping supply after the cutting head 105 completes a single cut, thus achieving continuous cutting. On the other hand, the transmission design of the double-headed rack 1007 ensures that the movable plate 3 can maintain the transmission connection with the driven rack 1003 even after adjusting the offset angle. No matter what angle the cutting head 105 cuts at at an angle, the worktable 16 can always achieve stepping supply in the same direction. The structural design is reasonable and the linkage is strong.
