Description

Technical Field

[0001] This utility model relates to the field of high-speed circular saw technology, and in particular to a high-speed circular saw blade cooling and anti-clogging spray device. Background Technology

[0002] High-speed steel circular saw blades are high-hardness cutting tools made of alloys such as carbon, tungsten, molybdenum, chromium, and vanadium. They are suitable for milling, sawing, and blanking of materials such as steel, stainless steel, aluminum, and plastics.

[0003] High-speed circular saws are equipped with both high-pressure and low-pressure water-cooled nozzles during cutting operations to ensure the safety of the cutting material and saw blade, while also cleaning debris from the cutting crevices.

[0004] However, the high-pressure and low-pressure water-cooled nozzles mentioned above are usually set in fixed positions, which means that the saw blade can only cut fixed types of materials, which is not conducive to flexible use.

[0005] To address the aforementioned issues, a high-speed circular saw blade cooling and anti-clogging spray device is proposed. Utility Model Content

[0006] The main purpose of this invention is to provide a cooling and anti-clogging spray device for high-speed circular saw blades, which solves the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A high-speed circular saw blade cooling and anti-clogging spray device includes a circular saw body, the circular saw body includes a protective cover and a saw blade, the protective cover is provided with a spray mechanism, and the spray mechanism is provided with a spray adjustment mechanism.

[0009] The spraying mechanism includes a pressure reducing box that can be detachably installed on the top of the protective cover. A tee is sealed and inserted into the top of the pressure reducing box. A first water distribution hose is inserted into one side wall of the tee. A second water distribution hose is inserted into the outer side wall of the pressure reducing box. A high-pressure spray head is connected to one bottom end of the first water distribution hose, and a low-pressure spray frame is connected to one bottom end of the second water distribution hose.

[0010] The spray adjustment mechanism includes a support frame and a rotating mechanism that are detachably fixed to the protective cover. A first telescopic tube welded to the top of the high-pressure spray head is fixed on the support frame, and a second telescopic tube welded to the top of the low-pressure spray frame is provided on the outside of the rotating mechanism.

[0011] Furthermore, the water outlet of the high-pressure spray head is aligned with the cutting gap between the saw blade and the material being cut.

[0012] Furthermore, the low-pressure spray frame is made of metal tubing with an internal tubular structure. A first spray hole in the strip shape is provided on the side wall of the low-pressure spray frame facing the saw blade, and a second spray hole in the circle is provided on the bottom wall of the low-pressure spray frame.

[0013] Furthermore, the extension stroke of the first telescopic tube is 10cm, and the extension stroke of the second telescopic tube is 12cm.

[0014] Furthermore, the rotating mechanism includes a fixed cover that is fixed to the cover screw, and a rotating shaft is mounted at the center of the fixed cover via a bearing. A spiral spring is clamped between the outer peripheral wall of the rotating shaft and the inner wall of the fixed cover.

[0015] Furthermore, one outer end of the rotating shaft is fixedly connected to the wall of the second telescopic tube.

Detailed Implementation

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-4 As shown in the figure, this embodiment provides a high-speed circular saw blade cooling and anti-clogging spray device, including a circular saw body 1. The circular saw body 1 includes a protective cover 101 and a saw blade 102. A spray mechanism 2 is provided on the protective cover 101, and a spray adjustment mechanism 3 is provided on the spray mechanism 2. The spray mechanism 2 includes a pressure reducing box 202 that is detachably installed on the top of the protective cover 101. A tee 201 is sealed and inserted into the top of the pressure reducing box 202. A first water distribution hose 203 is inserted into one side wall of the tee 201, and a first water distribution hose 203 is inserted into the outer side wall of the pressure reducing box 202. A second water distribution hose 204 is connected, and a high-pressure spray head 203a is connected to one bottom end of the first water distribution hose 203. A low-pressure spray frame 204a is connected to one bottom end of the second water distribution hose 204. The spray adjustment mechanism 3 includes a support frame 301a that is detachably fixed to the cover 101 and a rotating mechanism 303. A first telescopic pipe 301 that is welded to the top of the high-pressure spray head 203a is fixed on the support frame 301a. A second telescopic pipe 302 that is welded to the top of the low-pressure spray frame 204a is provided on the outside of the rotating mechanism 303.

[0026] In the above structure, the first water distribution hose 203 and the second water distribution hose 204 are both elastic telescopic hoses, which can conveniently extend and retract to supply water when the high-pressure spray head 203a and the low-pressure spray frame 204a are flexibly adjusted in position; the pressure reducing box 202 is used to reduce the pressure of the high-pressure water source and distribute it to the low-pressure spray frame 204a, so that it sprays out a low-pressure water column to cool the outer wall of the saw blade 102. The high-pressure spray head 203a is directly connected to the high-pressure water source from the tee 201 to form a high-pressure water column.

[0027] The water outlet of the high-pressure spray head 203a is aligned with the cutting gap between the saw blade 102 and the material being cut. This arrangement allows the high-pressure water jet to cool the saw teeth and the material, and also to clean the waste inside and outside the gap. The waste at the top outside the gap is washed away by the high-pressure water jet diverted by the saw blade 102, while the waste inside is washed away with the rotation direction.

[0028] The low-pressure spray frame 204a is a metal tube with an internal tubular structure, providing good support. The middle section has a U-shaped bent tube structure. The low-pressure spray frame 204a has a strip-shaped first spray hole 204b on the side wall facing the saw blade 102, and a circular second spray hole 204c on the bottom wall. The low-pressure spray frame 204a is located at a lower position on both sides of the saw blade 102. This arrangement helps to clean up the waste adhering to the saw blade 102 during cutting in a timely manner, preventing it from being blown into the protective cover 101.

[0029] The telescopic stroke of the first telescopic tube 301 is 10cm, and the telescopic stroke of the second telescopic tube 302 is 12cm.

[0030] In the above scheme, in the U-shaped bend structure of the low-pressure spray frame 204a, a section of pipe parallel to the arc-shaped outer wall of the protective cover 101 is 10cm away from the protective cover 101. This distance is the maximum adjustable distance of the low-pressure spray frame 204a through the second telescopic pipe 302. If the distance is greater than this, the protective cover 101 will be blocked.

[0031] The rotating mechanism 303 includes a fixed cover 303a that is screwed to the protective cover 101. A rotating shaft 303b is mounted at the center of the fixed cover 303a via a bearing. A spiral spring 303c is clamped between the outer peripheral wall of the rotating shaft 303b and the inner wall of the fixed cover 303a. This arrangement allows the bottom arc surface of the low-pressure spray frame 204a to be arbitrarily supported and lifted when facing materials with irregular structures. It can be adjusted by telescopic extension via the second telescopic tube 302 and by rotation via the rotating mechanism 303, and can be reset after processing.

[0032] One outer end of the rotating shaft 303b is fixedly connected to the wall of the second telescopic tube 302.

[0033] The working principle of this device is as follows:

[0034] When in use, the device connects to an external high-pressure water source via the three-way connector 201. The water enters the high-pressure spray head 203a through the first water distribution hose 203. The high-pressure spray water jet aligns with the saw teeth of the saw blade 102, the material, and the cutting gap to achieve cooling and cleaning of waste. The water enters the low-pressure spray frame 204a through the second water distribution hose 204. The first spray hole 204b aligns with the outer wall of the saw blade 102 and cools the saw blade 102 through the low-pressure spray water jet. The second spray hole 204c aligns with the top of the material, and in conjunction with the flushing of the high-pressure spray water jet, washes the waste on both sides of the top of the gap to the outside, preventing it from falling back into the gap and thus preventing blockage.

[0035] When dealing with materials of different shapes and cutting depths, the top of the material abuts against the arc-shaped bottom of the low-pressure spray frame 204a and the bottom of the high-pressure spray head 203a, causing them to rise along the second telescopic tube 302 and the first telescopic tube 301 respectively, maintaining adaptive adjustment of the spray position. The high-pressure spray head 203a is always aligned with the saw teeth, the material, and the cutting gap, while the low-pressure spray frame 204a is always directly above the material, allowing for continued spraying of the saw blade 102 and the top of the material. Simultaneously, the second telescopic tube 302 can also rotate around the center outside the protective cover 101 via the rotation of the rotating shaft 303b along the rotating mechanism 303, achieving adjustment of the low-pressure spray pipe in the X / Z directions. After adjustment, the first telescopic tube 301 and the second telescopic tube 302 return to their initial positions under gravity, and the rotating mechanism 303 returns to its initial position under the action of the spiral spring 303c.

[0036] With the above structure, the position of the spray head can be adaptively adjusted when cutting irregular materials, ensuring normal water cooling and cleaning of saw blade 102 and also facilitating the processing of saw blade 102 at different cutting depths.

[0037] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0038] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
