Description
Technical Field
[0001] This utility model belongs to the field of cutting device technology, specifically relating to a metal tube cutting device. Background Technology
[0002] Metal tube products are widely used in various fields, such as construction, machinery manufacturing, automobile manufacturing, and aerospace. In the construction industry, metal tubes are commonly used as supporting structural components; in the machinery manufacturing industry, metal tubes are widely used as key components in the manufacture of parts such as drive shafts and hydraulic cylinders; in the automobile manufacturing industry, metal tubes are used in key components such as automobile suspension systems and steering systems; and in the aerospace industry, metal tubes are highly favored due to their high strength and corrosion resistance.
[0003] When cutting metal pipes, a circular saw is generally used. Since the unprocessed pipes are usually quite long, sometimes several meters, they need to be cut into multiple equal-length segments according to production specifications. During cutting, a pneumatic clamp is usually used to hold the part of the pipe close to the cutting position, and then the circular saw is controlled to run and move towards the pipe to complete the cutting. However, after each cut, the operator needs to manually remove the cut pipe segments from one side of the clamp and stack them in a collection container, which affects processing efficiency. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a metal pipe cutting device that eliminates the need for operators to manually remove the cut steel pipes and place them in a collection container. The cut steel pipes can be automatically transferred and collected, and the next cutting action can be performed simultaneously during the automatic output and collection process, greatly improving production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal tube cutting device, including a machine base, with two sets of support seats on the top of the machine base. A clamping device and a cutting device are respectively installed on the top of the two sets of support seats. A support roller frame is provided on one side of the machine base, and a positioning and automatic output mechanism is provided on the other side of the machine base. The positioning and automatic output mechanism includes a first bracket, with two limiting plates installed on the top of the first bracket. One of the limiting plates has a through-hole adjustment groove, and the top of the limiting plate with the adjustment groove has a scale. An L-shaped distance is provided between the two limiting plates. The L-shaped positioning plate has a through hole on one side plate and is connected to a bolt. One end of the bolt passes through an adjustment groove and is threaded to a nut. The top of the L-shaped positioning plate has a scale marking plate. A rotating plate is rotatably installed between the two sets of limiting plates. A third cylinder is rotatably installed between the first bracket and the rotating plate. A second bracket is connected to one side of the first bracket. The top of the second bracket has a ramp. A fourth cylinder is installed on the side of the ramp. A baffle is installed at the end of the piston rod of the fourth cylinder. A control pedal switch is provided on the front side of the machine.
[0006] The beneficial effects of this invention are as follows: After completing one cutting action, the device can depress the output control pedal, and the PLC controller controls the third cylinder to drive the rotating plate downwards, causing the steel pipe above the third cylinder to slide towards the ramp and move onto the ramp. Under the action of gravity, the steel pipe rolls until it contacts the baffle, which blocks it and keeps it parallel to the baffle. Then, the third cylinder drives the rotating plate to reset, and the fourth cylinder drives the baffle to rise. The steel pipe, no longer blocked, rolls downwards again and falls into the collection box, completing the automatic collection of the steel pipe. Then, the fourth cylinder drives the baffle to reset. During the automatic output and collection of the steel pipe, the operator can simultaneously pull the steel pipe so that one end of its remaining part abuts against the L-shaped positioning plate again, allowing for another cut. In this way, the operator does not need to manually remove the cut steel pipe and place it in the collection container. The cut steel pipe can be automatically transferred and collected. During the automatic output and collection of the steel pipe, the next cutting action can be performed simultaneously, greatly improving production efficiency.
[0007] As a further improvement to the above technical solution: the clamping device includes a first clamping mounting base and a second clamping mounting base fixedly installed on the top of the support base. A first clamping block is screwed and fixedly installed on one side of the first clamping mounting base, and a first cylinder is fixedly installed on one side of the second clamping mounting base. A second clamping block is fixedly installed at the end of the piston rod of the first cylinder.
[0008] The PLC controller controls the first cylinder to push the second clamping block closer to the first clamping block, and the first and second clamping blocks work together to clamp and fix the steel pipe.
[0009] As a further improvement to the above technical solution: the cutting device includes a circular saw mounting base installed on the top of the support base, a machine arm is rotatably mounted on one side of the circular saw mounting base, a second cylinder is rotatably connected between the machine arm and the machine base, a motor is mounted on one side of the machine arm, the output end of the motor is fixed to the saw blade mounting base, a saw blade is fixedly mounted on the saw blade mounting base, and a protective cover is also provided on the outer side of a section of the machine arm.
[0010] When cutting steel pipes, the motor runs, driving the saw blade to rotate, while the second cylinder drives the machine arm to press down, cutting the steel pipe through the saw blade.
[0011] To support the steel pipe:
[0012] As a further improvement to the above technical solution: the support roller frame includes a frame body, and the top inner side of the frame body is provided with evenly arranged rotating rollers.
[0013] The beneficial effect of this improvement is that when cutting long steel pipes into sections, the uncut part of the steel pipe can be placed on top of the rotating roller, and the rotating roller supports the steel pipe, making cutting easier.
[0014] As a further improvement to the above technical solution: the starting point value of the scale is the horizontal distance between it and the saw blade.
[0015] The starting point of the scale is the horizontal distance between it and the saw blade. The distance reflected by the scale is the distance between it and the saw blade, which meets the requirement of positioning the steel pipe according to the cutting length.
[0016] To enhance the structural strength of the L-shaped positioning plate:
[0017] As a further improvement to the above technical solution: a reinforcing plate is fixedly installed on the inner side of the L-shaped positioning plate.
[0018] The beneficial effects of this improvement are: the reinforcing plate is used to strengthen the structural strength of the L-shaped positioning plate and prevent the side plate in contact with the steel pipe from tilting during long-term use.
[0019] To prevent the L-shaped positioning plate from sliding:
[0020] As a further improvement to the above technical solution: an anti-slip pad is fitted onto the outer side of the bolt located between the limiting plate and the nut.
[0021] The beneficial effect of this improvement is that when the nut is tightened, the anti-slip pad and the limiting plate are in close contact to prevent slippage and avoid the L-shaped positioning plate from sliding.
[0022] As a further improvement to the above technical solution: the control pedal switch is equipped with a PLC controller inside, and the top of the control pedal switch is equipped with two sets of pedal switches, namely a cutting control pedal switch and an output control pedal switch. The cutting control pedal switch is connected to the first cylinder, the second cylinder and the motor through the PLC controller, and the output control pedal switch is connected to the third cylinder and the fourth cylinder through the PLC controller.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0032] like Figure 1-6 As shown, a metal pipe cutting device includes a machine base 1. Two sets of support seats 2 are provided on the top of the machine base 1. A clamping device 3 and a cutting device 9 are respectively installed on the top of the two sets of support seats 2. A support roller frame 17 is provided on one side of the machine base 1, and a positioning and automatic output mechanism 20 is provided on the other side of the machine base 1. The positioning and automatic output mechanism 20 includes a first bracket 21. Two limiting plates 22 are installed on the top of the first bracket 21. One of the limiting plates 22 has a through-hole adjustment groove 23. The top of the limiting plate 22 with the adjustment groove 23 has a scale 24. An L-shaped positioning plate 25 is provided between the two limiting plates 22. A through hole is provided on one side plate and a bolt 27 is inserted and connected to it. One end of the bolt 27 passes through the adjustment groove 23 and is threadedly connected to the nut 28. The top of the L-shaped positioning plate 25 is provided with a scale marking plate 30. A rotating plate 31 is rotatably installed between the two sets of limiting plates 22. A third cylinder 32 is rotatably installed between the first bracket 21 and the rotating plate 31. A second bracket 33 is connected to one side of the first bracket 21. A ramp 34 is provided on the top of the second bracket 33. A fourth cylinder 35 is installed on the side of the ramp 34. A baffle 36 is installed at the end of the piston rod of the fourth cylinder 35. A control pedal switch 37 is provided on the front side of the machine base 1.
[0033] After completing one cutting action, the device can depress the output control pedal, which, via the PLC controller, controls the third cylinder 32 to rotate the rotating plate 31 downwards. This causes the steel pipe above the third cylinder 32 to slide towards the ramp 34 and move onto the ramp. Under gravity, the steel pipe rolls until it contacts the baffle 36, which then blocks it, keeping it parallel to the baffle 36. Subsequently, the third cylinder 32 drives the rotating plate 31 to reset, and the fourth cylinder 35 drives the baffle 36 to rise. The unblocked steel pipe then rolls downwards again and falls into the collection box, completing the automatic collection of the steel pipe. The fourth cylinder 35 then drives the baffle 36 to reset. During the automatic output and collection of the steel pipe, the operator can simultaneously pull the steel pipe so that one end of the remaining part is again against the L-shaped positioning plate 25 for another cut. In this way, the operator does not need to manually remove the cut steel pipe and place it in the collection container. The next cutting action can be performed simultaneously during the automatic output and collection of the steel pipe, greatly improving production efficiency.
[0034] The clamping device 3 includes a first clamping mounting base 4 and a second clamping mounting base 6 fixedly installed on the top of the support base 2. A first clamping block 5 is screwed and fixedly installed on one side of the first clamping mounting base 4. A first cylinder 7 is fixedly installed on one side of the second clamping mounting base 6. A second clamping block 8 is fixedly installed at the end of the piston rod of the first cylinder 7.
[0035] The PLC controller controls the first cylinder 7 to push the second clamping block 8 close to the first clamping block 5, and the first clamping block 5 and the second clamping block 8 work together to clamp and fix the steel pipe.
[0036] The cutting device 9 includes a circular saw mounting base 10 installed on the top of the support base 2. An arm 11 is rotatably mounted on one side of the circular saw mounting base 10. A second cylinder 12 is rotatably connected between the arm 11 and the machine base 1. A motor 13 is mounted on one side of the arm 11. The output end of the motor 13 is fixed to a saw blade mounting base 14. A saw blade 15 is fixedly mounted on the saw blade mounting base 14. A protective cover 16 is also provided on the outer side of a section of the arm 11.
[0037] When cutting steel pipes, motor 13 runs, driving saw blade 15 to rotate, while second cylinder 12 drives arm 11 to press down, cutting steel pipes through saw blade 15.
[0038] The support roller frame 17 includes a frame body 18, and the top inner side of the frame body 18 is provided with evenly arranged rotating rollers 19.
[0039] When cutting long steel pipes into sections, the uncut portion of the steel pipe can be placed on top of the rotating roller 19, which supports the steel pipe and facilitates cutting.
[0040] The starting point value of the scale 24 is the horizontal distance between it and the saw blade 15.
[0041] The starting point value of scale 24 is the horizontal distance between it and saw blade 15. Thus, the distance value reflected by scale 24 is the distance between it and saw blade 15, which meets the requirement of positioning the steel pipe according to the cutting length.
[0042] A reinforcing plate 26 is fixedly installed on the inner side of the L-shaped positioning plate 25.
[0043] The reinforcing plate 26 is used to strengthen the structural strength of the L-shaped positioning plate 25 and prevent the side plate in contact with the steel pipe from tilting during long-term use.
[0044] An anti-slip pad 29 is fitted onto the outer part of the bolt 27 located between the limiting plate 22 and the nut 28.
[0045] When the nut 28 is tightened, the anti-slip pad 29 and the limiting plate 22 are in close contact, providing an anti-slip effect and preventing the L-shaped positioning plate 25 from sliding.
[0046] The control pedal switch 37 is equipped with a PLC controller inside. The top of the control pedal switch 37 is equipped with two sets of pedal switches, namely a cutting control pedal switch and an output control pedal switch. The cutting control pedal switch is connected to the first cylinder 7, the second cylinder 12 and the motor 13 through the PLC controller. The output control pedal switch is connected to the third cylinder 32 and the fourth cylinder 35 through the PLC controller.
[0047] The working principle and usage process of this utility model are as follows: When using this device, place the container for collecting steel pipes, such as a collection box, below the ramp 34. Adjust the position of the L-shaped positioning plate 25 according to the cutting length of each section of the steel pipe. During adjustment, loosen the nut 28, and then adjust the position of the L-shaped positioning plate 25 by sliding between the bolt 27 and the adjusting groove 23. Determine the adjustment position of the L-shaped positioning plate 25 by cooperating with the scale marking plate 30 and the scale 24, so that the horizontal distance between the L-shaped positioning plate 25 and the saw blade 15 is consistent with the cutting length of the steel pipe. After the adjustment is completed, retighten the nut 28. When tightened, the anti-slip pad 29 and the limiting plate 22 are in close contact to prevent slippage. Then, the steel pipe to be cut is placed on the rotating roller 19, and one end of the steel pipe is pulled through between the first clamping block 5 and the second clamping block 8 so that it abuts against the L-shaped positioning plate 25, and cutting can begin. The cutting action of this device is controlled by stepping on the cutting control pedal switch 37. The PLC controller controls the first cylinder 7 to push the second clamping block 8 close to the first clamping block 5. The first clamping block 5 and the second clamping block 8 work together to clamp and fix the steel pipe. Immediately afterwards, the motor 13 starts running, driving the saw blade 15 to rotate, and at the same time, the first cylinder 7 pushes the second clamping block 8 close to the first clamping block 5. The first clamping block 5 and the second clamping block 8 work together to clamp and fix the steel pipe. Then, the motor 13 starts running, driving the saw blade 15 to rotate. Two cylinders 12 drive the machine arm 11 downwards, cutting the steel pipe through the saw blade 15. After the machine arm 11 descends to its lowest position, the motor 13 stops running. At the same time, the second cylinder 12 drives the machine arm 11 to reset, and the first cylinder 7 drives the second clamping block 8 to reset. At this time, the output control pedal is pressed, and the PLC controller controls the third cylinder 32 to drive the rotating plate 31 to rotate downwards, causing the steel pipe above the third cylinder 32 to slide towards the ramp 34 and move onto the ramp 34. Under the action of gravity, the steel pipe rolls until it contacts the baffle 36, which blocks it and keeps it parallel to the baffle 36. Then the third cylinder... Cylinder 32 drives the rotating plate 31 to reset, and the fourth cylinder 35 drives the baffle 36 to rise. The steel pipe, no longer obstructed, rolls downwards again and falls into the collection box, completing the automatic collection of the steel pipe. Then, the fourth cylinder 35 drives the baffle 36 to reset. During the automatic output and collection of the steel pipe, the operator can simultaneously pull the steel pipe so that one end of its remaining part is again against the L-shaped positioning plate 25 for recutting. In this way, the operator does not need to manually remove the cut steel pipe and place it in the collection container. The next cutting action can be carried out simultaneously during the automatic output and collection of the steel pipe, greatly improving production efficiency.
