Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machine technology, and in particular to an aluminum alloy pipe cutting machine for vehicle frame production. Background Technology

[0002] Aluminum alloy tube cutting machines for bicycle frame production are specialized equipment for cutting aluminum alloy tubes. Their design and function are tailored to meet the precise and efficient cutting requirements of aluminum alloy tubes during bicycle frame production. The working principle of these machines is primarily based on rotary cutting and automatic feeding. A motor drives the cutting blades to rotate, while an automatic feeding device feeds the aluminum alloy tubes into the cutting area, thus achieving automated cutting. During the cutting process, the machine precisely controls the operation according to preset cutting parameters to ensure cutting quality.

[0003] In the current pipe cutting machine, the pipe is placed directly on two support rollers during use. The distance between the support rollers is fixed, which makes it impossible to place pipes with a diameter smaller than the distance between the support rollers. At the same time, it is not easy to place square pipes.

[0004] An existing patent (publication number: CN207942043U) discloses an aluminum alloy tube cutting machine for vehicle frames, which includes a support column, a fixed crossbar mounted on the support column, the fixed crossbar and the support column being an integral structure, a square frame mounted on the fixed crossbar, a first threaded cylinder mounted on the square frame, a first threaded post mounted on the first threaded cylinder, and a first rotating plate mounted at one end of the first threaded post. By rotating the first threaded post mounted on the first threaded cylinder, the machine advances the roller forward, thereby clamping the alloy tube to be cut. The degree of roller advancement can be adjusted according to the width of the clamped alloy tube.

[0005] To address the aforementioned issues, existing patents propose a solution where the first threaded post mounted on the first threaded cylinder is rotated to adjust the roller's advance based on the width of the clamped alloy tube. However, due to the relatively low melting point of aluminum alloy, it is prone to oxidation during cutting due to high temperatures, generating fumes that can easily harm workers if dispersed in the air. Summary of the Invention

[0006] The purpose of this utility model is to provide an aluminum alloy tube cutting machine for vehicle frame production, which can draw in the fumes generated during aluminum alloy tube cutting. The filter screen is made of activated carbon and filter mesh, so that the fumes can be purified and filtered when passing through the filter screen. The two filter screens can be disassembled and replaced by the positioning holes and positioning rods, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy tube cutting machine for vehicle frame production, including a cutting machine base, a fixing frame fixed on the upper surface of the cutting machine base, and a cutting mechanism for cutting aluminum alloy tubes on the upper surface of the fixing frame;

[0008] The cutting mechanism includes an adjusting electric cylinder, which is fixed to the upper surface of the fixed frame by bolts. A drive motor is fixed to the telescopic end of the adjusting electric cylinder, and a cutting blade is fixed to the power output shaft of the drive motor. A protective shell is provided on the outer surface of the cutting blade and is fixedly connected to the drive motor.

[0009] Preferably, the left side of the protective shell is connected to an air outlet pipe, and two filter screens are installed inside the air outlet pipe.

[0010] Preferably, one end of the cutting blade is fixed with a drive shaft, and the end of the drive shaft is fixed with a negative pressure blade.

[0011] Preferably, a positioning hole is provided inside one of the filter screens, and a positioning rod is inserted into the positioning hole.

[0012] Preferably, two fixing plates are fixed on the right side of the machine base, and the upper end of each of the two fixing plates is provided with a clamping mechanism for clamping the aluminum alloy tube.

[0013] Preferably, the clamping mechanism includes a clamping member, which is fixed to the upper end of the two fixed plates. Two clamping cylinders are symmetrically fixed to the outer surface of the clamping member, and clamping plates are fixed to the telescopic ends of the two clamping cylinders.

[0014] Preferably, a stepper motor is fixed to one end of the clamping plate, and a roller is fixed to the power output shaft of the stepper motor, with a rubber sleeve covering the outer surface of the roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The cutting mechanism can draw in the fumes generated during the cutting of aluminum alloy tubes. The filter screen is made of activated carbon and filter mesh, which can purify and filter the fumes as they pass through the filter screen. The two filter screens can be disassembled and replaced easily through the positioning holes and positioning rods.

[0017] 2. The clamping mechanism ensures the stability of the clamped parts. The stepper motor on the clamping plate drives the roller to rotate, thereby driving the aluminum alloy tube to rotate.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A tube cutting machine for aluminum alloy tube production for vehicle frame manufacturing includes a cutting machine base 1, a fixing frame 2 fixed on the upper surface of the cutting machine base 1, and a cutting mechanism for cutting aluminum alloy tubes on the upper surface of the fixing frame 2.

[0028] The cutting mechanism includes an adjusting electric cylinder 3, which is fixed to the upper surface of the fixed frame 2 by bolts. A drive motor 31 is fixed to the telescopic end of the adjusting electric cylinder 3. A cutting blade 32 is fixed to the power output shaft of the drive motor 31. A protective shell 33 is provided on the outer surface of the cutting blade 32 and is fixedly connected to the drive motor 31. An air outlet pipe 34 is connected to the left side of the protective shell 33. Two filter screens 35 are installed inside the air outlet pipe 34. A drive shaft 36 is fixed to one end of the cutting blade 32. A negative pressure blade 37 is fixed to the end of the drive shaft 36. A positioning hole 4 is opened inside one of the filter screens 35. A positioning rod 5 is inserted into the positioning hole 4.

[0029] By adopting the above technical solution, before using the aluminum alloy tube cutting machine for frame production, the aluminum alloy tube to be processed is first placed between two clamping plates 72, so that the end of the aluminum alloy tube to be cut is below the cutting blade 32. Through the fixing bracket 2 set on the cutting machine base 1, the adjusting electric cylinder 3 drives the drive motor 31 to move vertically, thereby causing the cutting blade 32 to move above the aluminum alloy tube. At this time, the drive motor 31 drives the cutting blade 32 to rotate, cutting the aluminum alloy tube. The protective shell 33 can play a role in... The protective shell 33 serves a protective function, and when the cutting blade 32 rotates, it drives the transmission shaft 36 to rotate, which in turn drives the negative pressure blade 37 to rotate. At this time, the air inside the protective shell 33 is drawn into the exhaust pipe 34, creating a negative pressure at the lower end of the protective shell 33, which draws in the fumes generated during the cutting of the aluminum alloy tube. The filter plate 35 is made of activated carbon and a filter screen, which purifies and filters the fumes as they pass through it. The two filter plates 35 can be disassembled and replaced easily through the positioning holes 4 and positioning rods 5.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, two fixing plates 6 are fixed on the right side of the cutting machine base 1. The upper end of each fixing plate 6 is provided with a clamping mechanism for clamping aluminum alloy tubes. The clamping mechanism includes a clamping component 7, which is fixed on the upper end of the two fixing plates 6. Two clamping cylinders 71 are symmetrically fixed on the outer surface of the clamping component 7. The telescopic ends of the two clamping cylinders 71 are fixed with clamping plates 72. One end of the clamping plate 72 is fixed with a stepper motor 73. The power output shaft of the stepper motor 73 is fixed with a roller 74. The outer surface of the roller 74 is covered with a rubber sleeve 75.

[0031] By adopting the above technical solution, the clamping cylinder 71 on the clamping member 7 can drive the clamping plate 72 to move, thereby clamping and limiting the aluminum alloy tube. The fixed plate 6 can ensure the stability of the clamping member 7. The stepper motor 73 on the clamping plate 72 can drive the roller 74 to rotate, thereby driving the aluminum alloy tube to rotate. The rubber sleeve 75 plays an anti-slip role, performing a rotary cutting operation on the aluminum alloy tube.

[0032] Working principle: The clamping cylinder 71 on the clamping member 7 drives the clamping plate 72 to move, thereby clamping and limiting the aluminum alloy tube. The fixing frame 2 on the cutting machine base 1 causes the adjusting electric cylinder 3 to drive the drive motor 31 to move vertically, thereby moving the cutting blade 32 above the aluminum alloy tube. At this time, the drive motor 31 drives the cutting blade 32 to rotate, cutting the aluminum alloy tube. When the cutting blade 32 rotates, it drives the transmission shaft 36 to rotate, and the transmission shaft 36 drives the negative pressure blade 37 to rotate. At this time, the air inside the protective shell 33 is drawn into the exhaust pipe 34, which creates a negative pressure at the lower end of the protective shell 33, drawing in the fumes generated during the cutting of the aluminum alloy tube. The fumes are purified and filtered as they pass through the filter screen 35. The two filter screens 35 can be disassembled and replaced easily through the positioning holes 4 and positioning rods 5. The fixing plate 6 ensures the stability of the clamping parts 7. The stepper motor 73 on the clamping plate 72 can drive the roller 74 to rotate, thereby driving the aluminum alloy tube to rotate.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
