Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically to a water pipe cutting device. Background Technology

[0002] Automotive cooling pipes are typically made from cut metal, and there are various cutting processes, including abrasive wheel cutting, sawing, flame cutting, and laser cutting. Regardless of the type of metal pipe cutting equipment, heat is generated during processing. To reduce the temperature of the metal during cutting, cutting oil is usually used to cool the cutting blade and the metal pipe. However, existing cutting oils often mix with the metal shavings, resulting in oil waste. Furthermore, recycling the cutting oil requires collecting and filtering the mixture of cutting oil and shavings, increasing workload and requiring a large amount of cutting oil to be prepared in advance. Therefore, a water pipe cutting device is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a water pipe cutting device to solve the above-mentioned defects caused by the prior art.

[0004] A water pipe cutting device includes a cutting table, a collection tank installed inside the cutting table, the upper end of the collection tank penetrating the top wall of the cutting table, a filter screen inserted into the inner bottom side of the collection tank near the cutting table, a water pump installed on the inner bottom side of the cutting table, the inlet end of the water pump being connected to the inside of the collection tank via a pipe, and the outlet end of the water pump being connected to a nozzle installed on the inner side wall of the collection tank near the top via a pipe, the collection tank having a through hole on the lower side wall of the nozzle, the through hole slidingly engaging with a pipe fitting.

[0005] Preferably, a bracket is installed on the table surface of the cutting table and on one side of the collection tank. A first cylinder is installed on the bracket, and a support frame is installed at the output end of the first cylinder. A saw blade is rotatably connected between symmetrical connecting plates on the bottom side of the support frame. The saw blade is rotated by a first motor installed on one side of the connecting plate. A guide rod is installed at the upper end of the support frame and symmetrically at the position of the first cylinder. The guide rod is slidably connected to the bracket.

[0006] Preferably, a mounting frame is installed on the table surface of the cutting table and symmetrically on both sides of the collection tank. A second cylinder is installed on the mounting frame, and a connecting frame is installed at the lower end of the second cylinder. A limiting roller is rotatably connected to the connecting frame. A second motor is installed on the side wall of the mounting frame, and a moving roller is installed at the output end of the second motor. The moving roller is located below the limiting roller, and the grooves on the moving roller and the limiting roller respectively clamp the two sides of the pipe.

[0007] Preferably, the cutting table is hinged to a door on the side wall in the direction of filter screen removal.

[0008] Preferably, the upper side of the collection trough is provided with an arc-shaped sidewall to increase the collection range.

[0009] The advantages of this invention are as follows: This invention uses a water pump to extract the cutting oil filtered by the filter screen from the collection tank, and sprays it onto the cutting positions of the saw blade and pipe fittings through a nozzle to cool them down. The debris generated by the saw blade cutting the pipe fittings is blocked by the arc-shaped wall and falls into the collection tank. Then, the mixture of debris and cutting oil is filtered by the filter screen and falls into the inner bottom of the collection tank, realizing the cutting oil circulation operation. This reduces the use of cutting oil and avoids waste, and also reduces the operation of operators to recover and filter the cutting oil, thus improving efficiency. Attached Figure Description

The water pump 4 is electrically connected to a local power supply, and an oil-rubber sealing ring is installed on the contact side of the filter screen 3 with the collection tank 2 to prevent cutting oil from leaking out from the edge gaps of the filter screen 3.

[0016] In this embodiment, a bracket 8 is installed on the table surface of the cutting table 1, located on one side of the collection tank 2. A first cylinder 9 is mounted on the bracket 8, and a support frame 10 is mounted on the output end of the first cylinder 9. A saw blade 11 is rotatably connected between symmetrical connecting plates on the bottom side of the support frame 10. The saw blade 11 is rotated by a first motor 12 mounted on one side of the connecting plate. A guide rod 13 is installed on the upper end of the support frame 10, symmetrically positioned with the first cylinder 9, and the guide rod 13 is slidably connected to the bracket 8. The first motor 12 is electrically connected to the field power supply, and a distance sensor for detecting the movement of the pipe fitting 7 is installed on the bracket 8 to facilitate the detection of the cutting length of the pipe fitting 7.

[0017] In this embodiment, a mounting frame 14 is installed on the table surface of the cutting table 1, symmetrically on both sides of the collection tank 2. A second cylinder 15 is mounted on the mounting frame 14, and a connecting frame 16 is mounted on the lower end of the second cylinder 15. A limiting roller 17 is rotatably connected to the connecting frame 16. A second motor 18 is mounted on the side wall of the mounting frame 14, and a moving roller 19 is mounted on the output end of the second motor 18. The moving roller 19 is located below the limiting roller 17, and the grooves on the moving roller 19 and the limiting roller 17 respectively clamp the two sides of the pipe 7. The second motor 18 is electrically connected to the field power supply. The second motor 18 drives the moving roller 19 to rotate, and the moving roller 19 drives the pipe 7 to move, sending the pipe 7 to the lower end of the saw blade 11 for cutting. The cut pipe 7 is then moved onto the conveyor belt by the moving roller 19 to move to the next workstation.

[0018] In this embodiment, a door 20 is hinged to the side wall of the cutting table 1 on the side facing the direction of filter screen 3 disassembly. The door 20 is equipped with a handle. By opening the door 20 with the handle, the filter screen 3 can be manually pulled out, and the debris on the filter screen 3 can be cleaned and collected for remelting and casting into pipe fitting 7.

[0019] In this embodiment, the upper side of the collection groove 2 is provided with an arc-shaped sidewall to increase the collection range. The arc-shaped sidewall increases the collection range, making it easier to collect debris when it rebounds upon contact with the sidewall.

[0020] The working principle of this utility model is as follows: The second cylinder 15 is activated to move the connecting frame 16 downwards, causing the arc-shaped sidewall of the limiting roller 17 to abut against the upper side of the pipe 7, and cooperating with the arc-shaped groove of the moving roller 19 to clamp the pipe 7. The second motor 18 is activated to drive the moving roller 19 to rotate, and the moving roller 19 drives the pipe 7 through the through hole 6, through the inner side of the collecting groove 2, and abut against and clamp onto the limiting roller 17 and the moving roller 19 on the other side. Subsequently, the first cylinder 9 is activated to move the support frame 10 downwards, and the support frame 10 drives... The saw blade 11 moves downward, and the first motor 12 starts to drive the saw blade 11 to rotate and cut the pipe 7. The water pump 4 starts to draw the cutting oil filtered by the filter screen 3 from the collection tank 2 and sprays it through the nozzle 5 at the cutting position of the saw blade 11 and the pipe 7 to cool the pipe 7 and the saw blade 11. The debris generated by the saw blade 11 cutting the pipe 7 is blocked by the arc wall and falls into the collection tank 2. Then the mixture of debris and cutting oil is filtered by the filter screen 3 and falls into the inner bottom of the collection tank 2 to realize the cutting oil circulation operation.

[0021] This invention uses a water pump 4 to extract the cutting oil filtered by the filter screen 3 from the collection tank 2, and sprays it through the nozzle 5 onto the cutting positions of the saw blade 11 and the pipe fitting 7 to cool them down. The debris generated by the saw blade 11 cutting the pipe fitting 7 is blocked by the arc-shaped wall and falls into the collection tank 2. Then, the mixture of debris and cutting oil is filtered by the filter screen 3 and falls into the inner bottom of the collection tank 2 to achieve cutting oil circulation, reducing the use of cutting oil and avoiding waste, and reducing the operation of operators to collect and filter cutting oil, thus improving efficiency.
