DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0028] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] Example, see Figure 1 and Figure 4 , which is an embodiment of the present invention, proposes a saw blade center-mounted anti-vibration double-support hot saw machine, including a base 1, a slide 2, a rotary drive mechanism 3, a saw blade 4, a support shaft 5, and the slide 2 is slidably connected to the base 1; the rotary drive mechanism 3 is arranged on the slide 2; the saw blade 4 is arranged on the output shaft of the rotary drive mechanism 3, and the axial direction of the saw blade 4 is arranged perpendicular to the sliding direction of the slide 2; the support shaft 5 is rotatably arranged on the slide 2, and is located on the side of the saw blade 4 away from the rotary drive mechanism 3, and the support shaft 5 is coaxially arranged and connected with the saw blade 4.

[0031] In this embodiment, taking the slide 2 sliding in the front-back direction and the axis of the saw blade 4 being arranged in the left-right direction as an example, the slide 2 is slidably connected with the base 1, which can provide a stable moving foundation for the entire device. The rotary drive mechanism 3 includes a motor and a reducer, the output shaft of the motor is connected to the input shaft of the reducer through a transmission shaft, and the output shaft of the reducer is connected to the saw blade 4. The rotation speed of the saw blade 4 can be adjusted by the reducer. The protective shell 28 is arranged on the periphery of the rotary drive mechanism 3, making the overall appearance more neat and beautiful. During cutting, if the sawdust between the teeth cannot be cleaned in time, it will cause the "paste teeth" phenomenon, which greatly reduces the service life of the saw blade 4. In order to avoid this phenomenon, a cooling water delivery pipe 31 is arranged on the slide 2, and a nozzle is connected to the cooling water delivery pipe 31 to flush the saw blade 4. One end of the sliding drive mechanism 27 is connected to the base 1, and the other end is connected to the slide 2. Through the extension and retraction of the sliding drive mechanism 27, the slide 2 slides on the base 1, and the mechanized operation saves time and effort.

[0032] The rotary drive mechanism 3 is arranged on the slide 2, and the saw blade 4 is arranged on the output shaft of the rotary drive mechanism 3, which can ensure the stability and efficiency of the rotation. At the same time, a support shaft 5 is arranged on the side of the saw blade 4 away from the rotary drive mechanism 3, and the support shaft 5 is coaxially arranged and connected with the saw blade 4, so that the saw blade 4 is located between the rotary drive mechanism 3 and the support shaft 5, and the axes of the output shaft of the rotary drive mechanism 3, the saw blade 4 and the support shaft 5 are all arranged horizontally, and the three are concentric. When the rotary drive mechanism 3 drives the saw blade 4 to rotate for sawing, the rotary drive mechanism 3 and the support shaft 5 jointly play the role of supporting the saw blade 4. The double-sided support makes the forces on both sides of the saw blade 4 balanced when it is working, which can share the reaction force on the saw blade 4 and reduce the generation of torsional torque, so that the guide rail between the slide 2 and the base 1 no longer frequently bears lateral force, which can greatly reduce the wear degree of the guide rail and extend the service life of the guide rail, thereby reducing the maintenance cost and downtime of the equipment and improving production efficiency. The double-sided support operation of the saw blade 4 is one of the keys to improving sawing stability. The guide rail no longer bears lateral force frequently, which can avoid the gap between the guide rail and the pulley, effectively prevent the saw blade 4 from vibrating, improve the straightness of the saw blade 4 feeding and the stability of sawing, thereby extending the service life of the saw blade 4. The stable sawing process can also improve the accuracy and efficiency of sawing, improve the quality consistency of the product, and reduce the scrap rate. The sliding drive mechanism 27 can be a cylinder or a lead screw. The axis of the sliding drive mechanism 27 coincides with the center line of the thickness direction of the saw blade 4. This setting can also reduce the generation of lateral torsional torque, which is also one of the methods to improve sawing stability.

[0033] In order to facilitate the loading and unloading of the saw blade 4, the support shaft 5 is detachably connected to the saw blade 4. A chuck is provided on the periphery of the output shaft of the rotary drive mechanism 3 and the periphery of the support shaft 5. The chuck located on the periphery of the support shaft 5 is connected to the movable end of the hydraulic cylinder, and a rotating disk is provided on the side of the chuck facing the saw blade. When the hydraulic cylinder is extended, the chuck and the rotating disk on the periphery of the support shaft 5 are pushed toward the saw blade 4. When the saw blade 4 is clamped between the two chucks, the hydraulic cylinder stops moving to achieve axial compression and support of the saw blade 4. During the rotation of the saw blade 4, the chuck on the periphery of the support shaft 5 does not rotate, and the support shaft 5 and the rotating disk rotate synchronously with the saw blade 4, clamping the saw blade 4 during rotation. When the saw blade 4 needs to be disassembled, the support shaft 5 is separated from the saw blade 4, and the hydraulic cylinder is retracted so that the chuck and the rotating disk located on the periphery of the support shaft 5 are away from the saw blade 4, and then the saw blade 4 can be disassembled. Convenient loading and unloading and precise positioning of the saw blade are also the basic guarantee for a good working state.

[0034] Further, such as Figure 1 and Figure 2As shown, the base 1 has a slide groove 6 in the middle of the upper end surface, and the slide seat 2 has a raised slider 7 in the middle of the lower end surface. The end surface of the slider 7 close to the saw blade 4 is located on the side of the axis of the saw blade 4 away from the workpiece 26. It also includes a side guide rail 8 and a side pulley 9. The side guide rail 8 is arranged on the side wall of the slider 7, and the length direction of the side guide rail 8 is the same as the length direction of the slide groove 6; the side pulley 9 is rotatably arranged on the side wall of the slide groove 6, and there is at least one side pulley group on both side walls of the slide groove 6. All side pulleys 9 of the same side pulley group are arranged along the length direction of the slide groove 6 and are slidably connected to the same side guide rail 8.

[0035] Taking the case where the workpiece 26 to be cut is located in front of the base 1 as an example, the saw blade 4 is located at the front end of the slide 2 and the axis of the saw blade 4 is arranged in the left-right direction, and the front end surface of the slider 7 is located behind the axis of the saw blade 4 to avoid affecting the normal use of the saw blade 4. Through the cooperation of the V-shaped structure of the slide groove 6 and the slider 7, a stable guide and support can be provided for the sliding of the slide 2 on the base 1, so that the slide 2 can slide stably on the base 1, the vibration of the slide 2 can be avoided, and accurate position adjustment can be achieved to ensure that the saw blade 4 can accurately cut the workpiece 26. The side pulley 9 cooperates with the side guide rail 8 to avoid direct contact between the side wall of the slide 2 and the base 1, thereby reducing the friction between the slide 2 and the side wall of the slide groove 6, and reducing the resistance encountered by the slide 2 during movement.

[0036] Further, such as Figure 1 and Figure 2 As shown, there are at least two side pulley groups on the side wall of each slide 6, and all the side pulley groups are arranged in the up-down direction. The number of side guide rails 8 is equal to the number of side pulley groups, and they are arranged one by one. At least two side pulley groups are arranged in the up-down direction on the left and right side walls of the slide 6. Multiple side pulley groups and multiple side guide rails 8 play a supporting and guiding role together, making the slide 2 more stable during the sliding process, reducing shaking and deviation, and improving cutting accuracy. It can also disperse the weight of the slide 2 and improve the stability of the support.

[0037] Further, such as Figure 1 and Figure 3As shown, it also includes a lower guide rail 10 and a lower pulley 11. The lower guide rail 10 is arranged at the bottom of the slider 7, and the length direction of the lower guide rail 10 is the same as the length direction of the slide 6; the lower pulley 11 is rotatably arranged at the bottom of the slide 6, and the number of the lower pulleys 11 is multiple, and all the lower pulleys 11 are arranged along the length direction of the slide 6 and are slidably connected with the lower guide rail 10. The lower pulley 11 rolls on the lower guide rail 10, which can avoid the bottom surface of the slide 2 from directly contacting the base 1, thereby reducing the friction between the slider 7 and the bottom of the slide 6, and further reducing the resistance encountered by the slide 2 during movement. The lower guide rail 10, the lower pulley 11, the side guide rail 8 and the side pulley 9 together constitute an all-round guiding and supporting system, which can further improve the smoothness and stability of the slide 2, ensure that the slide 2 maintains an accurate position during movement, and improve the cutting quality.

[0038] Furthermore, the support shaft 5 is a gas expansion shaft which is locked with the saw blade 4 by inflation, so that the support shaft 5 and the saw blade 4 are matched without gap, ensuring that the saw blade 4 is well balanced, has the characteristics of fast locking and loosening, and can adapt to saw blades 4 with different inner diameters.

[0039] Further, such as Figure 4 As shown, the protective cover 12 is also included, and the protective cover 12 is arranged on the slide 2 and is located outside the saw blade 4. The protective cover 12 can isolate the saw blade 4 to prevent the operator from accidentally contacting the high-speed rotating saw blade 4 during work, thereby avoiding safety accidents, improving the safety of the equipment, and better protecting the personal safety of the operator.

[0040] Further, such as Figure 1 and Figure 8 As shown, it also includes a lifting drive mechanism 13 and a pressure wheel 14. The lower end of the lifting drive mechanism 13 is arranged on the base 1 and is located outside the slide 2. The pressure wheel 14 is rotatably arranged at the upper end of the lifting drive mechanism 13 and overlaps with the upper end surface of the slide 2. The axial direction of the pressure wheel 14 is perpendicular to the sliding direction of the slide 2. A set of lifting drive mechanisms 13 are arranged on both sides of the base 1 along the front-back direction. Each lifting drive mechanism 13 is connected with a pressure wheel 14. The axis of the pressure wheel 14 is arranged along the left-right direction. The lifting drive mechanism 13 can adjust the height of the pressure wheel 14 so that the pressure wheel 14 contacts with the upper end surface of the slide 2. When the slide 2 moves forward and backward, the pressure wheel 14 can rotate accordingly without affecting the normal movement of the slide 2. When the saw blade 4 cuts the workpiece 26, the pressure wheel 14 can apply a certain pressure to the slide 2 to prevent the slide 2 from jumping or shaking during the cutting process, thereby improving the cutting accuracy and stability.

[0041] Further, such as Figure 4 and Figure 8As shown, it also includes a frame 15, a conveying roller 16, a baffle 17, a push-pull driving mechanism 18, and a movable plate 19. The frame 15 is arranged on the outside of the saw blade 4, and the length direction of the frame 15 is the same as the axial direction of the saw blade 4; the conveying roller 16 is rotatably arranged on the frame 15, and the number of conveying rollers 16 is multiple, and all of the conveying rollers 16 are arranged along the length direction of the frame 15 for conveying the workpiece 26; the baffle 17 is arranged on one side of the frame 15, and the upper end surface of the baffle 17 is located above the conveying roller 16; one end of the push-pull driving mechanism 18 is arranged on the other side of the frame 15 and is located above the conveying roller 16; the movable plate 19 is arranged at the other end of the push-pull driving mechanism 18, and after the push-pull driving mechanism 18 is extended or retracted, the movable plate 19 is used to approach or move away from the baffle 17, and the baffle 17 and the movable plate 19 are between The conveying channel for the workpiece 26.

[0042] Taking the case where the frame 15 is located in front of the base 1, the baffle 17 is located at the rear side of the frame 15, and the movable plate 19 is located at the front side of the frame 1 as an example, the frame 15 provides support for the conveying roller 16 to ensure the stability of the conveying. The axis of the conveying roller 16 is arranged along the front-to-back direction, and all the conveying rollers 16 are arranged along the left-to-right direction. The front end of the push-pull driving mechanism 18 is connected to the frame 15, and the rear end of the push-pull driving mechanism 18 is connected to the movable plate 19. When the power mechanism drives the conveying roller 16 to rotate and convey the workpiece 26, the push-pull driving mechanism 18 is in a retracted state, and the distance between the movable plate 19 and the baffle 17 is greater than the width of the workpiece 26 along the front-to-back direction, so that the workpiece 26 can move smoothly between the movable plate 19 and the baffle 17. When the workpiece 26 moves to the position for cutting, the conveying roller 16 stops rotating, the push-pull driving mechanism 18 is extended first, the movable plate 19 is close to the baffle 17, and clamps the workpiece 26 together with the baffle 17, then the slide 2 moves forward, driving the saw blade 4 to move toward the workpiece 26, the rotary driving mechanism 3 drives the saw blade 4 to rotate, and cuts the workpiece 26. After the cutting is completed, the rotary driving mechanism 3 stops working, the slide 2 moves backward to the initial position, and the push-pull driving mechanism 18 shrinks back to the initial position. The power mechanism is used again to drive the conveying roller 16 to rotate and convey the workpiece 26, and it is ready for the next cutting. The use of the conveying roller 16 to realize the automatic conveying of the workpiece 26 can reduce manual operation, reduce labor intensity, and improve the conveying efficiency of the workpiece.

[0043] A group of pressure rods 30 are arranged above the frame 15 along the left-right direction, and a group of telescopic mechanisms 29 are arranged on the front and rear sides of the frame 15 along the left-right direction. The front and rear ends of the pressure rod 30 are respectively connected to the upper ends of the telescopic mechanisms 29 at the corresponding ends. When cutting is required, the telescopic mechanism 29 contracts so that the pressure rod 30 is placed on the workpiece 26 to press the workpiece 26. After the cutting is completed, the telescopic mechanism 29 extends so that the pressure rod 30 rises and separates from the workpiece 26, which can prevent the workpiece 26 from shaking up and down during the cutting process, thereby further improving the cutting accuracy.

[0044] Further, such as Figure 5 , Figure 6 and Figure 7 As shown, the baffle plate 17 and the movable plate 19 have an anti-slip layer 20 on one side facing the conveying channel, and the side has a mounting groove 21 and a guide groove 22, the mounting groove 21 is located between the upper and lower guide grooves 22, and the guide groove 22 is connected to the mounting groove 21, the width of the guide groove 22 is smaller than the width of the mounting groove 21, and also includes a slide bar 23, a conveying wheel 24, and an elastic member 25, the upper end of the slide bar 23 is plugged into the guide groove 22 located above the mounting groove 21 to form a sliding fit, and the lower end of the slide bar 23 is plugged into the guide groove 22 located above the mounting groove 21 to form a sliding fit, and the lower end of the slide bar 23 is plugged into the guide groove 22 located above the mounting groove 21 to form a sliding fit. The guide groove 22 below the mounting groove 21 is plugged in and forms a sliding fit; the conveying wheel 24 is rotatably arranged on the periphery of the slide bar 23 and is located in the mounting groove 21, and the axis of the conveying wheel 24 is vertically arranged; the elastic member 25 is located in the mounting groove 21, and there are elastic members 25 above and below the conveying wheel 24, the outer end of the elastic member 25 is connected to the slide bar 23, and the inner end of the elastic member 25 is connected to the baffle 17 or the movable plate 19. After the elastic member 25 is extended, the conveying wheel 24 is used to move toward the workpiece 26 and contact the workpiece 26.

[0045] Taking the case where the frame 15 is located in front of the base 1, the baffle 17 is located at the rear side of the frame 15, and the movable plate 19 is located at the front side of the frame 1 as an example, the front end surface of the baffle 17 and the rear end surface of the movable plate 19 are provided with a mounting groove 21, and the upper and lower parts of the mounting groove 21 are provided with guide grooves 22 connected thereto, and the width of the guide groove 22 along the left-right direction is smaller than the width of the mounting groove 21 along the left-right direction, the slide bar 23 is slidably arranged between the two guide grooves 22 on the upper line, the conveying wheel 24 is arranged on the periphery of the slide bar 23 and is located in the mounting groove 21, and the elastic member 25 can be extended and retracted in the left-right direction. When cutting is required, the push-pull driving mechanism 18 is extended, the workpiece 26 is clamped by the movable plate 19 and the baffle 17, and the workpiece 26 directly contacts the anti-slip layer 20 on the movable plate 19 and the baffle 17, the conveying wheel 24 is located in the mounting groove 21, and the elastic member 25 is compressed, which can prevent the workpiece 26 from deflecting during the cutting process. After the cutting is completed, the push-pull drive mechanism 18 contracts back to the initial position, and the elastic member 25 extends. Under the action of the elastic member 25, the slide bar 23 and the conveying wheel 24 both move toward the workpiece 26. A portion of the conveying wheel 24 protrudes out of the outside of the mounting groove 21 and contacts with the workpiece 26. When the conveying roller 16 conveys the workpiece 26 again, the workpiece 26 will not contact with the anti-slip layer 20 on the movable plate 19 and the baffle 17, but will contact with the conveying wheel 24. There is rolling friction between the workpiece 26 and the conveying wheel 24. While preventing the workpiece 26 from deviating, the friction force on the workpiece 26 during movement can be reduced.

[0046] The present invention is used in a specific manner, such as Figure 4 and Figure 8As shown, a plurality of slides 2 are arranged side by side in the left-right direction, and each slide 2 can slide in the front-back direction on the base 1. A plurality of conveying rollers 16 are arranged in the left-right direction on the frame 15 located in front of the base 1, and the workpiece 26 can be conveyed to the left or right.
