Detailed implementation manners
[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and effects according to the application of the present utility model. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0029] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] As Figure 1 And Figure 2 shown, an aluminum bar sawing device provided by an embodiment of the present utility model includes: a frame 1 and an oil spraying part;
[0031] The frame 1 is rotatably connected to the first drive wheel 2 and the second drive wheel 3. The first drive wheel 2 is located above the second drive wheel 3, and a saw band 4 is tensioned between the first drive wheel 2 and the second drive wheel 3;
[0032] The oil injection part includes a first exhaust fan 5, a Venturi tube 6, an oil delivery pipe 7 and an oil spray pipe 8. The impeller of the first exhaust fan 5 is coaxially connected to the first transmission wheel 2. The outlet of the first exhaust fan 5 is connected to the inlet of the Venturi tube 6. One end of the oil delivery pipe 7 is connected to the oil storage box 9, and the other end is connected to the throat of the Venturi tube 6. The outlet of the Venturi tube 6 is connected to one end of the oil spray pipe 8, and the other end of the oil spray pipe 8 is connected to the nozzle 10. The spraying direction of the nozzle 10 faces the side of the saw band 4.
[0033] The working process of an aluminum bar sawing device is as follows:
[0034] When the device saws the aluminum bar, the first transmission wheel 2 and the second transmission wheel 3 drive the saw band 4 to rotate. At the same time, the first transmission wheel 2 drives the impeller of the first exhaust fan 5 to rotate. The first exhaust fan 5 generates an air flow, and this air flow enters the Venturi tube 6 at a high speed, generating a negative pressure at the throat of the Venturi tube 6. This negative pressure causes the lubricating oil in the oil storage box 9 to enter the Venturi tube 6 along the oil delivery pipe 7. In the Venturi tube 6, the lubricating oil and the air flow are mixed and reach the nozzle 10 along the oil spray pipe 8, and are sprayed out from the nozzle 10 to the side of the saw band 4, playing a role in cooling and lubricating the saw band 4.
[0035] When using this device, the first exhaust fan 5 and the Venturi tube 6 are invested once, and high-speed air flow is automatically generated, without the need to additionally set up a compressed air pipe, reducing the continuous consumption of compressed air and lowering the equipment investment cost.
[0036] Specifically, the outlet of the first exhaust fan 5 is connected to the inlet of the Venturi tube 6 through a first air pipe 11. The first air pipe 11, the oil delivery pipe 7 and the oil spray pipe 8 are respectively made of plastic hose materials.
[0037] Specifically, the first transmission wheel 2 is connected to the impeller of the first exhaust fan 5 through a coupling.
[0038] Specifically, the volute of the first exhaust fan 5 is fixedly installed on the frame 1.
[0039] As Figure 1 shown, in the specific implementation manner, the oil storage box 9 and the Venturi tube 6 are at the same height.
[0040] In this implementation manner, specifically, the oil storage box 9 and the Venturi tube 6 are at the same height, and there is no potential energy difference between them; when this device does not saw the aluminum bar, the lubricating oil in the oil storage box 9 will not automatically flow to the Venturi tube 6. When this device saws the aluminum bar, the air flow passes through the Venturi tube 6, generating a negative pressure at the throat of the Venturi tube 6, and the lubricating oil in the oil storage box 9 flows to the Venturi tube 6 due to the pressure difference.
[0041] As Figure 1 shown, in the specific implementation manner, the oil storage box 9 is fixedly installed on the frame 1.
[0042] In this embodiment, specifically, the oil storage box 9 is fixedly installed on the side of the frame 1 away from the saw band 4.
[0043] As Figure 1 and Figure 3 shown, in a specific embodiment, the included angle between the spraying direction of the nozzle 10 and the side surface of the saw band 4 is less than 90°.
[0044] In this embodiment, specifically, the included angle between the spraying direction of the nozzle 10 and the side surface of the saw band 4 is less than 90°, which is convenient for the lubricating oil sprayed by the nozzle 10 to diffuse along the side surface of the saw band 4, avoiding excessive splashing and useless consumption of the lubricating oil.
[0045] As Figure 3 shown, in a specific embodiment, the number of the nozzles 10 is two, and the two nozzles 10 are symmetrically arranged on both sides of the saw band 4.
[0046] In this embodiment, specifically, the two nozzles 10 are symmetrically arranged on both side surfaces of the saw band 4 and are used to cool and lubricate both side surfaces of the saw band 4 simultaneously.
[0047] As Figure 1 shown, in a specific embodiment, it further includes an electric heating tape 12, and the electric heating tape 12 is wound around the axial side of the fuel injection pipe 8.
[0048] In this embodiment, specifically, in winter, after the lubricating oil is mixed with air, the lubricating oil is likely to condense. Now, the electric heating tape 12 is wound around the axial side of the fuel injection pipe 8, which is convenient for keeping the temperature of the mixture of the lubricating oil and air above the freezing point.
[0049] As Figure 1 and Figure 4 shown, in a specific embodiment, it further includes a second exhaust fan 13 and a plurality of baffle plates 14. The impeller of the second exhaust fan 13 is coaxially connected to the second transmission wheel 3. A cutting table is provided on the frame 1 below the first transmission wheel 2. A dust suction cavity 15 is provided inside the cutting table. A vertical cutting slit 16 is provided in the middle of the dust suction cavity 15. A plurality of dust suction slits 17 are arranged in sequence on the upper surface of the cutting table. The plurality of dust suction slits 17 are symmetrically distributed on both sides of the cutting slit 16. The saw band 4 passes through the cutting slit 16. The plurality of baffle plates 14 are symmetrically arranged in the dust suction cavity 15 on both sides of the saw band 4. The opposite side walls of the dust suction cavity 15 are respectively connected to one end of an air extraction pipe 18, and the other end of the air extraction pipe 18 is connected to the inlet of the second exhaust fan 13.
[0050] In this embodiment, specifically, the plurality of baffle plates 14 on each side of the saw band 4 are arranged staggeredly to form a baffle channel. Driven by the second exhaust fan 13, an air flow is formed from the middle of the dust suction cavity 15 towards both side walls. Driven by this air flow, the debris generated by sawing the aluminum rod passes through the cutting seam 16 and the dust suction seam 17 and then concentrates in the spaces on both sides of the dust suction cavity 15. At the same time, the debris rubs against the surface of the baffle plate 14, consuming the kinetic energy of the debris and preventing the debris from entering the exhaust pipe 18.
[0051] Specifically, the volute of the second exhaust fan 13 is fixedly installed on the frame 1.
[0052] As Figure 4 shown, in a specific embodiment, it further includes a bottom shell 19. An opening is provided at the lower end of the dust suction cavity 15, and the bottom shell 19 is slidably connected to the opposite sides of the opening.
[0053] In this embodiment, specifically, a chute (slider) is provided at the edge of the bottom shell 19, and a slider (chute) is provided at the edge of the opening, so that the bottom shell 19 and the lower opening of the dust suction cavity 15 form a horizontal sliding fit relationship; when there is more debris deposited on the bottom shell 19, the bottom shell 19 is horizontally pulled out to facilitate the cleaning and collection of the debris.
[0054] As Figure 5 shown, in a specific embodiment, a filter layer 20 is provided between the baffle plate 14 and the side wall of the dust suction cavity 15.
[0055] In this embodiment, specifically, a filter layer 20 is provided between the outermost baffle plate 14 and the side wall of the dust suction cavity 15, which is convenient for filtering debris and further prevents the debris from entering the exhaust pipe 18.
[0056] Specifically, the filter layer 20 is made of filter cotton.
[0057] As Figure 4 shown, in a specific embodiment, the bottom shell 19 between the saw band 4 and the side wall of the dust suction cavity 15 is inclined towards the side wall of the dust suction cavity 15.
[0058] In this embodiment, specifically, the bottom shell 19 is inclined towards the side wall of the dust suction cavity 15, so that the debris entering the dust suction cavity 15 converges towards both sides of the dust suction cavity 15 along the inclined surface of the bottom shell 19.
[0059] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
