Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and in particular to a metal profile cutting device. Background Art

[0002] Cutting machines include mechanical cutting machines and chemical cutting machines. Mechanical cutting machines are divided into straight saw cutting machines and circular saw cutting machines according to the different cutting saws. Among them, circular saw cutting machines are more commonly used. Their saw disk is circular and is connected to the motor with a central shaft to make the saw disk rotate continuously to achieve cutting.

[0003] Depending on the material of the object being cut, in order to prevent overheating during the cutting process, the circular saw cutting machine needs to continuously spray water on the saw surface to cool it down when in use. The rotating saw disc will splash water and cutting debris. In order to avoid splashing and injuring people, a protective cover is often installed on the outer side of the upper part of the saw disc to block and slow down the splashing water and debris. However, the water and debris after being blocked and slowed down may fall into the cover, polluting the working environment of the cutting table, or condense and accumulate in the cover, causing friction or collision with the saw disc, affecting the performance of the saw disc.

DETAILED DESCRIPTION

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0036] Example

[0037] Please refer to Figures 1 to 7, this embodiment provides a metal profile cutting device, including a saw disk 40, which is transmission-connected to a motor; second, it includes a cover body 10, which is semicircular and covers the upper half of the saw disk 40, and the cover body 10 has an air intake 11; third, it includes at least one receiving plate 20, which is semicircular and is coaxially arranged in the cover body 10, and the inner ring of the receiving plate 20 is tightly connected to the cover body 10, and the outer ring of the receiving plate 20 is arranged close to the disk surface of the saw disk 40, so that a receiving groove 12 is formed between at least one receiving plate 20 and the inner wall of the cover body 10, and the air intake 11 is connected to the receiving groove 12; fourth, it includes a negative pressure mechanism, which is connected to the air intake 11 through a negative pressure pipe 30; fifth, it includes a water supply mechanism, which is used to continuously spray water on the saw disk 40.

[0038] The metal profile cutting device provided in this embodiment comprises a saw disc 40 for cutting and a water supply mechanism for continuously spraying water on the surface of the saw disc 40. Furthermore, a cover 10 is provided to block and decelerate the water and debris thrown up by the saw disc 40. Simultaneously, a receiving plate 20 is provided to form a receiving groove 12 to collect the blocked and decelerated water and debris, preventing them from falling into the cover 10 and contaminating the cutting table. Furthermore, an air intake 11, a negative pressure pipe 30, and a negative pressure mechanism are provided to vacuum the water and debris collected in the receiving groove 12, thereby continuously sucking the water and debris out of the receiving groove 12 and preventing them from continuously accumulating in the cover 10 and affecting the performance of the saw disc 40. The outer ring of the receiving plate 20 is positioned close to the surface of the saw disc 40 to reduce the size of the notch of the receiving groove 12, thereby improving the sealing performance of the receiving groove 12 and facilitating negative pressure suction.

[0039] In order to fully collect the thrown water and debris, the receiving plate 20 is composed of two pieces, and the two receiving plates 20 are symmetrically arranged with the saw disk 40 as the center plane. The two receiving plates 20 form a receiving groove 12 on both sides of the inner wall of the cover body 10; the inner wall of the top surface of the cover body 10 is an outwardly convex arc surface, so that the two sides of the inner wall of the top surface of the cover body 10 are smoothly connected to the two receiving grooves 12 respectively.

[0040] Through the above-mentioned arrangement, the water body thrown up by the saw disk 40 impacts the inner wall of the convex arc surface of the cover body 10 and is decelerated, and then flows along the inner wall of the cover body 10 from the high point in the middle to the low points on both sides, and flows into the two receiving grooves 12 respectively, thereby effectively collecting the water body and debris. If the receiving plate 20 is only set on one side, there will inevitably be a situation where water flows downward on the other side. If the receiving plates 20 are set on both sides, the situation of water flowing downward can be effectively avoided.

[0041] In order to facilitate the cleaning of impurities adhered to the surface of the receiving plate 20 and to protect the saw disk 40 when the cutting device stops, a semi-circular slide rail 13 is coaxially opened on the inner wall of the cover body 10, and a semi-circular slide bar 21 is protruding outward from the inner ring of the receiving plate 20. The slide bar 21 is slidably connected to the slide rail 13 so that the receiving plate 20 and the cover body 10 are coaxially rotatably connected; the saw disk 40 is eccentrically arranged with the cover body 10, and when the receiving plate 20 rotates to the upper semicircle, the top of the saw disk 40 is higher than the top of the receiving plate 20, so that the saw disk 40 is exposed; when the receiving plate 20 rotates to the lower semicircle, the bottom of the saw disk 40 is higher than the bottom of the receiving plate 20, so that the saw disk 40 is covered in the receiving plate 20.

[0042] Through the above arrangement, when the cutting device stops, the receiving plate 20 is rotated outward to be screwed out of the cover body 10 until the screwed-out end contacts the other end of the cover body 10 again and the entire receiving plate 20 is screwed out of the cover body 10. At this time, since the saw disk 40 and the cover body 10 are eccentrically arranged, the saw teeth of the exposed lower half of the saw disk 40 are covered between the two receiving plates 20, thereby protecting the saw disk 40 (that is, protecting the user); at this time, one side of the receiving groove 12 formed on the receiving plate 20 is exposed outward, which is convenient for cleaning, such as rinsing with water.

[0043] In order to prevent the receiving plate 20 from excessively rotating and causing it to completely separate from the cover body 10, limit plates 24 are respectively provided at both ends of the receiving plate 20 in the longitudinal direction to prevent the receiving plate 20 from excessively rotating.

[0044] By setting a limit plate 24, the rotation angle of the receiving plate 20 is limited. The limit plate 24 at one end is always stuck in the cover body 10 to prevent the receiving plate 20 from separating from the cover body 10. The limit plate 24 at the other end can be set to be more protruding. On the one hand, it prevents the rotated end of the receiving plate 20 from being inserted into the cover body 10. On the other hand, it is convenient for the user to push the receiving plate 20 back into the cover body 10.

[0045] Preferably, the limiting plate 24 that is always located inside the cover body 10 can be set to have the same cross-sectional shape as the inner wall of the cover body 10. When the receiving plate 20 is rotated outward, the limiting plate 24 can scrape off debris adhering to the inner wall of the cover body 10 and clean the inner wall of the cover body 10 at the same time.

[0046] In order to further enhance the protective effect of the receiving plate 20 on the saw disk 40, when the two receiving plates 20 are in a natural state, the outer rings of the two receiving plates 20 abut against each other; the receiving plate 20 is an elastic plate; the outer wall of the receiving plate 20 is connected to a plurality of pull rods 22, and the inner wall of the cover body 10 is coaxially provided with at least one semicircular pull rail 14, and the end of the pull rod 22 is detachably connected and slidingly matched with the pull rail 14. When the receiving plate 20 rotates to the upper semicircle and all the pull rods 22 are slidingly connected to the pull rail 14, the receiving plate 20 elastically deforms to form a sawing gap between the two receiving plates 20, and the width of the sawing gap is greater than the thickness of the saw disk 40.

[0047] Through the above-mentioned arrangement, when the receiving plate 20 is rotated out, the outer rings of the two receiving plates 20 abut against each other, thereby completely enclosing the saw teeth at the bottom of the saw disk 40 between the two receiving plates 20; on this basis, by setting the receiving plate 20 as an elastic plate, setting the pull rod 22 and the pull rail 14, when the receiving plate 20 is rotated back in the opposite direction, the end of the pull rod 22 is indirectly inserted into the pull rail 14, so that the pull rod 22 and the receiving plate 20 rotate along the pull rail 14 together. When the receiving plate 20 is completely screwed into the cover body 10, the pull rod 22 pulls the receiving plate 20 outward to form a gap between the receiving plate 20 and the saw surface of the saw disk 40, so as to form a sawing gap, which does not hinder the rotation of the saw disk 40 while approaching the saw surface of the saw disk 40 and preventing water and debris from falling down from the gap.

[0048] It should be noted that since the distance between the receiving plate 20 and the saw surface of the saw disk 40 is small, the air flow rate in the gap is faster during the rotation of the saw disk 40, which will cause the receiving plate 20 to be sucked toward the saw surface of the saw disk 40. At this time, the pull rod 22 can also effectively tighten the receiving plate 20 to prevent the receiving plate 20 from contacting the saw surface of the saw disk 40.

[0049] It should be noted that all the pull rods 22 are arranged on the same semicircular ring so that the pulling effect of each pull rod 22 is the same.

[0050] In order to adaptively adjust the width of the saw gap according to the different thicknesses of the saw disc 40, there are multiple pull rails 14, and the multiple pull rails 14 are coaxially arranged; the connecting plate 20 gradually approaches the inner wall of the cover body 10 radially inward; the pull rod 22 is slidably connected to the outer wall of the connecting plate 20 along the radial direction of the connecting plate 20.

[0051] By concentrically arranging a plurality of pull rails 14, the diameter of each pull rail 14 is different. At the same time, a connecting plate 20 is arranged to gradually approach the inner wall of the cover body 10 radially inward, so that it is arranged in a slant-like manner, and a pull rod 22 is arranged to slide radially. Since the length of the pull rod 22 remains unchanged, when it is necessary to increase the saw clearance, it is only necessary to slide the pull rod 22 with the pull rail 14 with a larger diameter. At this time, the pull rod 22 is closer to the outer ring of the connecting plate 20, and the outer ring of the connecting plate 20 is farther away from the inner wall of the cover body 10, so that the saw clearance can be increased; conversely, when it is necessary to reduce the saw clearance, it is only necessary to slide the pull rod 22 with the pull rail 14 with a smaller diameter. At this time, the pull rod 22 is closer to the inner ring of the connecting plate 20, and the inner ring of the connecting plate 20 is closer to the inner wall of the cover body 10, so that the saw clearance can be reduced.

[0052] Preferably, in order to optimize the sliding path of the pull rod 22, optimize the pulling performance between the pull rod 22 and the receiving plate 20, and optimize the covering effect of the receiving plate 20 on the saw teeth of the saw disk 40, the inner annular surface of the receiving plate 20 close to the cover body 10 is a concave surface, and the outer annular surface of the receiving plate 20 away from the cover body 10 is a convex surface.

[0053] In order to further explain the specific implementation method of the sliding connection between the pull rod 22 and the receiving plate 20, a plurality of sliding grooves 23 are evenly opened in the radial direction on the outer wall of the receiving plate 20. The sliding grooves 23 correspond one-to-one to the pull rods 22, and one end of the pull rod 22 is slidingly connected to the corresponding sliding groove 23; the pull rod 22 can be interference-fitted into the corresponding sliding groove 23.

[0054] Through the above-mentioned arrangement, a sliding groove 23 is provided to realize a sliding connection between one end of the pull rod 22 and the receiving plate 20; on this basis, through the above-mentioned arrangement, the receiving plate 20 is connected with an inner concave curved surface and an outer convex curved surface, so that its middle part is in a relatively flat state, so that the pull rod 22 can be embedded in the sliding groove 23 there, so that when the receiving plate 20 is screwed out, the pull rod 22 can be effectively stored.

[0055] Preferably, in order to provide a certain degree of adaptive compensation, the pull rod 22 is a hydraulic telescopic rod. Its telescopic amount is very small, only for adaptive compensation of slight deformation.

[0056] Since the outer ring of the receiving plate 20 is close to the saw surface of the saw disk 40, only a gap is reserved for the saw, resulting in a relatively closed receiving groove 12. When the negative pressure mechanism is working, the receiving groove 12 is in a strong negative pressure state, which can easily cause the cover body 10 to deform inward, affecting the structural performance of the cover body 10. The cover body 10 is provided with an air supply port 15, and the air supply port 15 and the air intake port 11 are respectively arranged on both sides of the cover body 10 in the thickness direction, and the air supply port 15 and the air intake port 11 are respectively arranged at both ends of the cover body 10 in the length direction.

[0057] By opening the air supply port 15, air flow is added to the cover body 10 to prevent it from deforming inward under negative pressure. By limiting the relative position of the air supply port 15 and the air intake port 11, the air flow path is optimized so that the air inhaled from the air supply port 15 flows along the length direction of the receiving groove 12, and carries away the water and debris in the receiving groove 12 along the way, and is finally sucked out from the air intake port 11.

[0058] In order to further explain the specific structure of the negative pressure mechanism, the negative pressure mechanism includes a negative pressure container 31 and a negative pressure impeller 32. The negative pressure impeller 32 is located in the negative pressure container 31 and is connected to the motor shaft of the cutting machine; the end of the negative pressure pipe 30 away from the air intake 11 is connected to the negative pressure container 31; the negative pressure container 31 is provided with an exhaust port 311, and the exhaust port 311 is equipped with a filter 312.

[0059] By setting up a negative pressure container 31, an exhaust port 311 and a filter 312, and setting a negative pressure impeller 32 in the negative pressure container 31, the rotation of the negative pressure impeller 32 is used to form a negative pressure suction force, so that water and debris are sucked into the negative pressure container 31, and the air flow and water can be discharged through the filter 312, so that the debris is collected in the negative pressure container 31, which is convenient for subsequent cleaning; on this basis, by setting the negative pressure impeller 32 to be connected with the motor shaft of the cutting machine, the cutting machine will synchronously drive the negative pressure impeller 32 to rotate when in use, thereby improving the synchronization of the entire device.

[0060] Please Figures 1 to 7 Based on the reference Figures 8 to 10 The water supply mechanism includes: a pair of spray guns 70, the two spray guns 70 are symmetrically arranged on both sides of the saw disk 40 with the saw disk 40 of the cutting machine as the center, and the head end of the spray gun 70 is tilted downward; the second includes a water carrying member 80, the water carrying member 80 is a soft rectangular sheet, the water carrying member 80 is arranged between the two spray guns 70, and is respectively connected to the side walls of the two spray guns 70, a counterweight 81 is provided on the top surface of the water carrying member 80, the counterweight 81 is slidably connected to the water carrying member 80, and both ends of the sliding path They are respectively the near saw point 82 and the far saw point 83, the near saw point 82 is located at the edge of the water-carrying part 80 close to the saw disk 40, and the far saw point 83 is close to the middle of the water-carrying part 80; the third includes a bracket, the tail ends of the two spray guns 70 are hinged to the bracket, and a reset torsion spring is provided at the hinge (not shown); when the counterweight 81 is located at the far saw point 83, the distance between the head ends of the two spray guns 70 is the outer sweeping spacing; when the counterweight 81 is located at the near saw point 82, the distance between the head ends of the two spray guns 70 is the spray-saw spacing.

[0061] By setting a water supply mechanism including a pair of spray guns 70 for continuously spraying water, a bracket is set to support the two spray guns 70, and the freedom of rotation of the spray guns 70 is provided by the shaft hinge, so that the head ends of the two spray guns 70 can be close to or away from each other to adjust the water spraying angle of the spray guns 70; on this basis, by setting a water-carrying part 80, the two spray guns 70 are connected as a whole, and a counterweight 81 is set on the water-carrying part 80, and the water-carrying part 80 is pressed down by the counterweight 81 to bend it, thereby driving the spray gun 70 to resist the reset torsion spring and rotate inward, so that the head ends of the two spray guns 70 are close to each other, and the head ends of the two spray guns 70 are both directed to the saw surface; on this basis, by setting the counterweight 81, it is possible to adjust the water spraying angle of the spray guns 70 at the near saw point 82 and The far saw point 83 slides along the water-carrying part 80, and limits the positions of the near saw point 82 and the far saw point 83, so that the position of the counterweight 81 can be adjusted, thereby the bending degree of the water-carrying part 80 can be adjusted, so that the distance between the head ends of the two spray guns 70 can be adjusted between the spray saw spacing and the outer sweep spacing; when in use, adjust the angle of the spray gun 70 so that its head end is tilted downward and aimed at the saw surface close to the saw groove. At this time, the water-carrying part 80 is tilted, and the counterweight 81 is located near the saw point 82 under the action of gravity. The spray gun 70 sprays water on the saw surface close to the saw groove, and the saw disk 40 entrains the water and throws it out through centrifugal force. The thrown water continuously impacts the top surface of the water-carrying part 80, and in the process pushes the counterweight 81 along the water-carrying part 80. Slide upward, so that the counterweight slides from the near saw point 82 to the far saw point 83. During the process, the position of the counterweight 81 gradually approaches the middle of the water-carrying part 80, the lever arm gradually shortens, and the force against the reset torsion spring gradually decreases, so that the bending degree of the water-carrying part 80 gradually decreases, thereby gradually increasing the distance between the head ends of the two spray guns 70, so that the water flow sprayed from the head end of the spray gun 70 gradually moves away from the saw surface and sweeps toward the saw groove, flushing out the debris and impurities in the saw groove. During the process, since the water flow sprayed from the spray gun 70 gradually moves away from the saw surface, the water flow entrained by the saw surface gradually decreases, resulting in a gradual decrease in the impact of the water flow on the water-carrying part 80, and the impact on the counterweight 81 also gradually decreases. Under the action of gravity, the counterweight 81 slides in the opposite direction from the far saw point 83 to the near saw point. At the saw point 82, the distance between the two spray gun heads 70 is gradually reduced and reset, and the saw groove is swept in the opposite direction again to flush out the debris and impurities in the saw groove, and then sprayed to the saw surface to cool down the part of the saw surface close to the saw groove. At this time, the water flow carried by the saw disk 40 increases again, and the counterweight 81 is punched up again, so that the above two processes are quickly alternated, thereby causing the spray gun head end to swing back and forth. During the swinging process, not only can the saw surface close to the saw groove be occasionally cooled, but the saw groove can also be sprayed at a high frequency to continuously clean the debris and impurities in the saw groove, thereby preventing the debris and impurities from further invading the gap between the saw surface and the wall of the saw groove, thereby solving the problem of the increase in local thermal effect of the saw disk 40 as the cutting depth increases from two aspects.

[0062] In order to further explain the counterweight 81 and its sliding structure, a slide groove 801 is opened on the top surface of the water-carrying part 80. The slide groove 801 is a linear groove. The slide groove 801 is parallel to the plane where the saw disk 40 is located. The end of the slide groove 801 close to the saw disk 40 is the near saw point 82, and the other end is the far saw point 83; the counterweight 81 is spherical, and the counterweight 81 is slidably connected to the slide groove 801 and is clamped in the slide groove 801.

[0063] By setting the slide groove 801 as a linear groove, the sliding path of the counterweight 81 is optimized, the path length is effectively shortened, and the switching frequency is increased.

[0064] Preferably, in order to make adaptive adjustments according to the thickness and diameter of different saw discs 40, the counterweight 81 includes a plurality of spheres with the same diameter and different masses, and the spheres with suitable masses can be selected according to different situations.

[0065] In order to facilitate the impact of water flow and lift the counterweight 81, the chute 801 is provided with a water flushing slope 8011 near the sawing point 82, and the slope of the water flushing slope 8011 is set at an obtuse angle to the bottom of the chute 801.

[0066] By providing the flushing slope 8011 , water can flow into the flushing slope 8011 and push the counterweight 81 upward from the bottom of the counterweight 81 , thereby improving the efficiency of pushing up the counterweight 81 .

[0067] In order to further explain the specific structure of the bracket, the bracket includes an articulated frame 90, an offset beam 91 and a base 92. The tail ends of the two spray guns 70 are respectively hinged to the articulated frame 90; the middle part of the articulated frame 90 is connected to the offset beam 91, and the offset beam 91 extends in a direction away from the saw surface of the saw disk 40; the end of the offset beam 91 away from the articulated frame 90 is connected to the base 92.

[0068] By setting the offset beam 91, the spray gun 70 is moved closer to the edge of the saw disc 40 from the side along the thickness direction of the saw disc 40, so that the entire bracket does not hinder the rotation of the saw disc 40, and the base 92 can be set on one side of the thickness direction of the saw disc 40 for easy fixation.

[0069] In order to make adaptive adjustments according to different types of saw discs 40 and the positions of the mechanisms around the saw disc 40, the offset beam 91 includes a vertically connected hinge section 911 and a telescopic section 912. The end of the hinge section 911 away from the telescopic section 912 is hinged to the hinge frame 90 and is provided with a locking member so that the hinge frame 90 can rotate in the vertical plane; the telescopic section 912 is slidably sleeved with an inner beam 913, and the inner beam 913 is connected to the base 92.

[0070] The above arrangement allows, on the one hand, the length of the offset beam 91 to be adjusted by extending and retracting the inner beam 913 and the telescopic section 912, thereby adjusting the installation position of the base 92. On the other hand, the hinged connection between the hinged section 911 and the hinged frame 90 allows the spray gun 70 to rotate in a vertical plane, thereby facilitating adjustment of the direction of the tip of the spray gun 70. The angle of the hinged connection can be fixed by providing a locking member, such as a screw and knob as shown in the figure, which only needs to be able to provide stable fixation.

[0071] In order to further optimize the directional adjustment of the spray gun 70, the base 92 is connected to an arc rail 93, which is a smooth, upward-curved arc-like shape; the end of the offset beam 91 away from the saw surface is slidably connected to the arc rail 93 and is provided with fasteners.

[0072] By providing a curved rail 93, the spray gun 70 can slide along it, adjusting the position of the rear end of the spray gun 70. By using the aforementioned hinge, after adjusting the rear end position, the front end can be adjusted using the hinge to more precisely set the direction of the spray gun 70 to accommodate the unique shapes of the objects being cut. The curved shape better matches the shape of the saw disc 40 cutting surface, further improving the fit during adjustment. Fasteners are provided to secure the curved rail 93 and the offset beam 91, such as the screws and knobs shown in the figure. These fasteners only need to provide stable fixation.

[0073] Preferably, in order to facilitate installation of the base 92 and adjustment of the angle of the arc rail 93 , a swivel post 94 is vertically provided on the top of the base 92 , and the bottom end of the arc rail 93 is connected to the swivel post 94 .

[0074] Preferably, in order to facilitate the adjustment of the overall setting height of the entire mechanism so that it matches different saw disc 40 cutting machines, a sleeve 95 is vertically provided on the top of the base 92, and the rotary column 94 is coaxially sleeved in the sleeve 95 and slides and rotates with the sleeve 95. The sleeve 95 is provided with a positioning piece.

[0075] Through the above arrangement, the height of the entire mechanism can be raised and lowered by the sliding fit between the sleeve 95 and the rotary post 94. The height of the rotary post 94 is fixed by providing a positioning member, such as a screw and a knob in the prior art, which only needs to be able to be stably fixed.

[0076] It should be noted that the spray gun 70 is connected to a water source (not shown) via a hose (not shown) and a water pump (not shown). The hose is used to enable the spray gun 70 to smoothly reciprocate. The water pump pressurizes the water, pumping it into the spray gun 70 and controlling the flow rate and pressure of the water sprayed from the spray gun 70.

[0077] Please Figures 1 to 10 Based on the reference Figures 11 to 14The outer edge of the saw disk 40 is provided with a plurality of strip-shaped water holes 41, and the water holes 41 pass through the saw disk 40 along the thickness direction of the saw disk 40. The water hole 41 has an outer end 411 and an inner end 412. The inner end 412 is located inside the saw disk 40, and the outer end 411 passes through the outer edge of the saw disk 40, so that the outer edge of the saw disk 40 is divided into a plurality of connecting parts 42, and each connecting part 42 is provided with a cutter head 43; the second includes a plurality of water diversion channels 50, which are evenly distributed on both sides of the saw disk 40, and one end of the water diversion channel 50 is arranged toward the center of the saw disk 40, and the other end is arranged toward the outer edge of the saw disk 40; the inner end 412 of each water hole 41 is connected to at least one water diversion channel 50.

[0078] By evenly arranging a plurality of water diversion channels 50 on the disk surface on both sides of the saw disk 40, when cooling water is continuously sprayed on the disk surface of the saw disk 40 at a fixed point, due to the continuous uniform rotation of the saw disk 40, the water flows into each water diversion channel 50 in turn near the water inlet end of the center of the saw disk 40, and basically keeps the water flow rate flowing into each water diversion channel 50 equivalent, and then flows along the water diversion channel 50 under the action of centrifugal force until it flows out from the water outlet end of the water diversion channel 50 and is thrown out along the edge of the saw disk 40. During the process, since a plurality of water diversion channels 50 are evenly distributed on both sides of the saw disk 40, the cooling water is evenly in contact with both sides of the saw disk 40 and is cooled, which effectively solves the problem of uneven cooling of the saw surface causing its structural performance. On this basis, a plurality of water holes 41 are opened on the outer edge of the saw disk 40, and the outer edge of the saw disk 40 is divided into a plurality of connecting parts 42. A cutter head 43 is set at each connecting part 42, and each water hole 41 is connected to at least one water diversion channel 50. When the cooling water flows out along the water diversion channel 50, it flows into the connected water hole 41, and flows along the edge of the water hole 41 to the blade spine and cutting surface of the cutter head 43, thereby cooling the blade spine and cutting surface. The cooling water flowing out of other water diversion channels 50 flows along the disk surface of the saw disk 40 to the side wall of the cutter head 43, and cools the side of the cutter head 43. The problem of not being able to effectively cool the cutter head 43 is solved by cooling each surface of the cutter head 43.

[0079] It should be noted that the uniform distribution of the water diversion channels 50 can be in two forms: overall uniformity and block uniformity. For example, the overall uniformity is that the water diversion channels 50 are all straight channels, are all arranged radially, and the angles between any two adjacent water diversion channels 50 are the same; the block uniformity is that the entire saw disk is evenly divided into 6 sector surfaces, and the water diversion channels 50 on all sector surfaces are arranged the same, but the shapes and angles of the multiple water diversion channels 50 on each sector surface are not necessarily the same.

[0080] In order to explain the specific shape of the water diversion channel 50 in detail, the entire water diversion channel 50 includes multiple straight channels 51 and multiple curved channels 52. The straight channels 51 extend along the diameter of the saw disk 40. The straight channels 51 correspond to and are connected to the water holes 41 one by one.

[0081] By setting up the water diversion channel 50 including two forms of a straight channel 51 and a curved channel 52, the straight channel 51 is used for rapid drainage, so that the cooling water quickly slides over the surface of the saw disk 40, and because it is connected to the water hole 41, the water discharged from the straight channel 51 quickly contacts the blade spine and cutting surface of the cutter head 43 for cooling; and the curved channel 52 has several inflection points, which effectively extends its length and extends the contact time of the cooling water therein with the surface of the saw disk 40, thereby fully cooling the saw disk 40.

[0082] It should be noted that the aforementioned curved flow channel 52 refers to a flow channel having inflection points, and the number of inflection points ≥1 is sufficient.

[0083] In order to improve the water diversion performance of the straight channel 51, one end of the straight channel 51 close to the center of the saw disk 40 is configured to be funnel-shaped.

[0084] Through the above arrangement, the diameter of the water inlet end of the straight channel 51 is increased, making it easier for cooling water to enter the straight channel 51.

[0085] In order to facilitate regular cleaning of the straight flow channel 51 and the curved flow channel 52, the straight flow channel 51 and the curved flow channel 52 are opened on the side away from the disk surface of the saw disk 40; a sealing ring 60 is coaxially provided on both sides of the saw disk 40. When the sealing ring 60 is connected to the saw disk 40, the straight flow channel 51 and the curved flow channel 52 are closed on the side away from the disk surface of the saw disk 40, and a gap is reserved between the sealing ring 60 and the saw disk 40.

[0086] Through the above arrangement, when it is necessary to clean the straight channel 51 and the curved channel 52, it is only necessary to remove the blocking ring 60 to open the straight channel 51 and the curved channel 52 on the side away from the saw surface. At this time, it can be rinsed with the water cavity. After the cleaning is completed, the blocking ring 60 is put back and the blocking ring 60 is used to block the straight channel 51 and the curved channel 52 on the side away from the saw surface, so that only the water inlet and water outlet of the two are open.

[0087] In order to facilitate the entry of cooling water into the water diversion channel 50, the end of the water diversion channel 50 facing the center of the saw disk 40 is the water inlet end, and the radius of the inner ring of the sealing ring 60 is smaller than the distance between the water inlet end of any water diversion channel 50 and the center of the saw disk 40.

[0088] Through the above arrangement, a groove capable of storing water is formed between the inner ring of the sealing ring 60 and the saw disk 40, so that the cooling water first rushes into the groove and then enters the water inlet end of the water diversion channel 50 under the action of centrifugal force.

[0089] Preferably, in order to ensure the uniformity of water distribution in the water diversion channel 50 on the basis of the above-mentioned effects, the water inlet end of each water diversion channel 50 is at the same distance from the center of the saw disk 40, so that the annular surface formed by the water inlet end of the water diversion channel 50, the inner ring of the sealing ring 60 and the saw disk 40 form a water storage ring groove 61.

[0090] Preferably, the disc surface of the saw disc 40 is grooved in the radial direction to form a direct current channel 51. The direct current channel 51 formed by digging satisfies the notch opening setting, is convenient for cleaning, and has a simple structure.

[0091] In order to improve the uniformity of the curved flow channel 52, a plurality of gratings 521 are cross-arranged on the disk surface of the saw disk 40 to divide it into a plurality of diamond-shaped lattices 522. Each grating 521 has a plurality of water holes 5211, and each water hole 5211 is connected to at least two lattices 522, so that the plurality of lattices 522 are connected to form a curved flow channel 52.

[0092] Through the above arrangement, randomness is utilized to increase the complexity of the bending of the curved channel 52 within a limited range, and the high randomness feedback is utilized to improve the uniformity of the cooling water in the curved channel 52 when cooling the saw blade 40. Using the grating 521 to construct the curved channel 52 not only ensures the structural performance of all parts of the curved channel 52, but also allows the side away from the saw blade 40 to be naturally open for easy cleaning.

[0093] In order to further utilize cooling water, the sealing ring 60 is provided with a plurality of water collection holes 601 , which penetrate the sealing ring 60 along the thickness direction so that the water collection holes 601 are connected to at least one lattice 522 . The water collection holes 601 are arc holes, and the water collection holes 601 extend along the ring line of the sealing ring 60 .

[0094] By providing a water collection hole 601 in the sealing ring 60, when the water supply end, such as a spray gun, is not spraying water at a fixed point, its path can pass over the surface of the sealing ring 60. During the process, cooling water enters the lattice 522 through the water collection hole 601 and flows along the curved flow channel 52. By limiting the shape and extension direction of the water collection hole 601, it can be connected to multiple lattices 522 as much as possible without leaking water (under the action of centrifugal force).

[0095] Preferably, in order to further prevent mechanical breakage of the edge of the saw disk 40, the saw disk 40 is radially opened with multiple buffer holes 44, one end of the buffer hole 44 passes through the outer edge of the saw disk 40, and the other end is connected to a circular hole, which is connected to the bending flow channel 52.

[0096] The buffer hole 44, with a circular inner end, is conventionally used in the art and is used to buffer the vibration of the saw blade 40 during cutting. By connecting the circular hole to the curved flow channel 52, some cooling water discharged through the curved flow channel 52 enters the circular hole, flows along the circular hole wall into the buffer hole 44, and is discharged along the wall of the buffer hole 44.

[0097] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
