Description

Technical Field

[0001] This utility model mainly relates to the field of double-head saw technology, specifically an adjustable 45-degree CNC double-head saw with automatic secondary feeding. Background Technology

[0002] In the field of aluminum alloy profile cutting, double-headed saws are commonly used. The angle of a double-headed saw can be adjusted according to the required angle of the profile being cut, achieving the desired cut angle. When cutting aluminum alloy profiles for air filters, the angle of the double-headed saw is generally controlled at 45 degrees.

[0003] To meet the needs of different cutting lengths, the spacing of a double-headed saw needs to be adjusted according to the target length before processing. Existing double-headed saws typically only support the profile using two support tables fixed to one side of the saw. For profiles that can be cut a second time, to reduce manual labor, a structure for supporting the cutting waste and automatically feeding it is required. However, existing double-headed saws struggle to achieve both adjustable spacing and support for the cutting waste, as well as automatic feeding. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. It mainly provides an adjustable 45-degree CNC double-head saw with automatic secondary feeding, which solves the technical problem mentioned in the background that existing double-head saws cannot achieve both adjustable spacing and support for cutting waste and automatic feeding.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An adjustable 45-degree CNC double-head saw with automatic secondary feeding includes a main frame, with support housings on both sides above the main frame. Inside the support housings are cutting saw components for cutting aluminum alloy profiles, and on the support housings are support components for supporting the aluminum alloy profiles and automatically feeding them a second time.

[0007] Preferably, the cutting saw assembly includes a cutting saw mounting bracket, which is disposed inside the support housing. The cutting saw mounting bracket is provided with a first motor and a cutting saw body. A first tensioning pulley is sleeved on the output end of the first motor and the rotating shaft of the cutting saw body.

[0008] Preferably, the support housing is provided with a working feed cylinder, one end of the extension rod of the working feed cylinder is fixedly connected to the cutting saw mounting frame, a second guide rail is provided inside the upper part of the support housing, the cutting saw mounting frame is slidably connected to the second guide rail, a support platform is provided on the side of the support housing opposite to the working feed cylinder, and a clamping cylinder is provided on the support housing.

[0009] Preferably, a second motor is provided on one side of the support housing, a spur gear is provided on the output shaft of the second motor, and a rack is provided on the main frame of the equipment, with the spur gear meshing with the rack.

[0010] Preferably, the support assembly includes a scissor structure, with both ends of the scissor structure connected to the two side support housings respectively, and the middle connection point of the scissor structure slidably connected to the main frame of the equipment via a connecting rod.

[0011] Preferably, the support assembly further includes a support frame, which is disposed on a support housing on one side. A first conveying roller is disposed on the support frame, and a third motor is disposed on the support frame, wherein one of the shafts of the first conveying roller is connected to the output end of the third motor.

[0012] Preferably, a second conveying roller is rotatably connected at the middle connection point of the scissor structure, and a support rod is provided at the end of the second conveying roller away from the scissor structure. The main frame of the equipment is provided with a first guide rail, and the support rod is slidably connected to the first guide rail. A second tensioning pulley is sleeved between the first conveying roller and one of the second conveying rollers, and a third tensioning pulley is sleeved between each pair of adjacent second conveying rollers.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the support component supports the aluminum alloy profile, and the support component will adjust the distance between the two support shells as the support shell on one side moves, thereby adjusting the cutting length of the aluminum alloy profile. At the same time, the support component will also adjust the distance to adapt to the distance between the support shells. After the aluminum alloy profile is cut by the cutting saw component, the excess aluminum alloy profile will also be supported by the support component. As the cut aluminum alloy profile is transported away, the support component will transport the excess aluminum alloy profile to the bottom of the cutting saw component for cutting. This can prevent the excess material from falling after the aluminum alloy profile is cut. At the same time, if there is enough excess material to cut, secondary feeding can be realized for cutting. While protecting the material from falling and breaking, automatic secondary feeding can be performed.

[0014] The second guide rail adopts an inverted guide rail structure, with the cutting saw assembly suspended inside the support housing. This way, the debris generated by the cutting saw assembly will fall off naturally due to gravity, and will not easily accumulate on the second guide rail, ensuring the long-term stable operation of the guide rail.

[0015] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0026] Please refer to the appendix carefully. Figures 1-5 An adjustable 45-degree CNC double-head saw with automatic secondary feeding includes a main frame 1, with support housings 2 on both sides above the main frame 1. The support housings 2 are equipped with cutting saw components for cutting aluminum alloy profiles, and the support housings 2 are equipped with support components for supporting the aluminum alloy profiles and automatically feeding them secondary.

[0027] The specific operating procedure of this utility model is as follows: The aluminum alloy profile is transported to the top of the support assembly. Then, the distance between the two support housings 2 is adjusted according to the length to be cut of the aluminum alloy profile. One of the two support housings 2 is fixed on the main frame 1 of the equipment, and the other is slidably connected to the main frame 1 of the equipment. The distance between the two support housings 2 is adjusted by moving one of the support housings 2. The support assembly will also adjust the distance between them as the support housings 2 move. After the distance is adjusted, the aluminum alloy profile is cut at a 45-degree angle by the cutting saw assembly. After the aluminum alloy profile is cut, the excess material will not fall off the support assembly. If the excess material can be cut again, the cut aluminum alloy profile can be removed from the support assembly. Then, the excess material is transported to the bottom of the two cutting saw assemblies for secondary cutting through the support assembly.

[0028] Please refer to Figure 4 The cutting saw assembly includes a cutting saw mounting bracket 4, which is located inside the support housing 2. A first motor 5 and a cutting saw body 6 are mounted on the cutting saw mounting bracket 4. A first tensioning pulley 7 is sleeved on the output end of the first motor 5 and the rotating shaft of the cutting saw body 6.

[0029] The cutting saw uses a 350mm circular saw blade. The cutting saw mounting bracket 4 is fixedly installed at a 45-degree angle inside the support housing 2. When the first motor 5 is started, the first motor 5 drives the cutting saw body 6 to rotate through the first tension belt pulley 7 to cut the aluminum alloy profile.

[0031] The aluminum alloy profile is placed on two support platforms 3. The aluminum alloy profile on the support platform 3 is pressed down and fixed by the pressing cylinder 21. The support platform 3 is provided with a 45-degree groove for the cutting saw body 6 to cut the profile. The second guide rail 22 is installed upside down inside the support housing 2. The second guide rail 22 is used to restrict the linear movement of the cutting saw mounting frame 4. The working cylinder 8 is started, and the working cylinder 8 pushes the cutting saw mounting frame 4 forward. When the cutting saw body 6 is inserted into the 45-degree cutting groove and contacts the aluminum alloy profile, the aluminum alloy profile is cut.

[0032] Please refer to Figure 5 A second motor 9 is provided on one side of the support housing 2. A spur gear 10 is provided on the output shaft of the second motor 9. A rack 11 is provided on the main frame 1 of the equipment. The spur gear 10 meshes with the rack 11.

[0033] A second motor 9 is installed on the support housing 2, which is slidably connected to the main frame 1 of the equipment. When the second motor 9 is started, it drives the spur gear 10 to rotate. The spur gear 10 drives the support housing 2 to move horizontally left and right through the meshing rack 11, adjusting the distance between it and another fixed support housing 2. A distance sensor can be installed on the support housing 2 to detect the distance between the two support housings 2. This allows the support assembly to determine the length of the subsequent aluminum alloy profile to be moved during the secondary feeding.

[0034] Please refer to Figures 1-3The support assembly includes a scissor structure 12, with both ends of the scissor structure 12 connected to the two side support housings 2 respectively. The middle connection point of the scissor structure 12 is slidably connected to the main frame 1 of the equipment via a connecting rod. The support assembly also includes a support frame 14, which is mounted on one side support housing 2. At least three first conveyor rollers 13 are mounted on the support frame 14, with the length direction of the first conveyor rollers 13 parallel to the width direction of the main frame 1 of the equipment. A third motor 15 is mounted on the support frame 14, with the shaft of one of the first conveyor rollers 13 connected to the output end of the third motor 15.

The support rod 19 is slidably connected to the first guide rail 20. The second tension pulley 17 is sleeved between the first conveyor roller 13 and one of the second conveyor rollers 16. The third tension pulley 18 is sleeved between each pair of adjacent second conveyor rollers 16.

[0035] When the support housing 2 moves to adjust the spacing, the support housing 2 will compress or stretch the scissor structure 12. The scissor structure 12 will adjust the spacing between multiple second conveying rollers 16. The support frame 14 is fixedly installed on the support housing 2 and will move with the movement of the support housing 2. One end of the second conveying roller 16 is rotatably connected to the scissor structure 12 and the other end is rotatably connected to the support rod 19. The second conveying roller 16 is supported by the scissor structure 12 and the support rod 19. The third motor 15 is started, and the third motor 15 drives the first conveying roller 13 to rotate. The first conveying roller 13 drives one of the second conveying rollers 16 to rotate through the second tension pulley 17. The second conveying roller 16 drives multiple second conveying rollers 16 to rotate through the third tension pulley 18. The rotation of the first conveying roller 13 and the second conveying roller 16 can transport the aluminum alloy profile to the two support platforms 3. The first conveying roller 13, the second conveying roller 16 and the highest point of the support platform 3 are on the same horizontal plane.
