[0031] Working steps:

[0032] S1. First, assemble the device, place multiple hoses on the first tube placement groove 231 and the second tube placement groove 243, make the ends of the hoses abut against the positioning block 28, start the cylinder 22, and the output end of the cylinder 22 drives the lower pressure plate 25 to fall, the tube cutting assembly 27 is connected to the workbench 24, and the cutter seat 273 enters the positioning groove 244 to fix the hose, and the lower pressure plate 25 continues to move downward, driving the tube cutting assembly 27 to continue to move, and the cutting blade 274 cuts the hose. After the cutting blade 274 contacts the cutting blade pad 29, the hose is completely cut off, and the cylinder 22 is started again to drive the tube cutting assembly 27 to reset, and the cutter seat 273 is separated from the positioning groove 244, releasing the limit on the hose, and the cut hose can be removed, and the above steps are repeated to continue cutting the hose until the required number of hoses of this size is reached.

[0033] S2. When cutting hoses of different lengths, first, turn the hand wheel 46, the threaded rod 41 moves in the nut 43, the push rod 42 drags the slider 5 to slide in the slide groove 11, and adjust the position of the second pipe cutter 3. When the distance between the cutting blade 274 on the first pipe cutter 2 and the cutting blade 274 on the second pipe cutter 3 reaches the distance of the hose to be produced, the position adjustment of the second pipe cutter 3 is completed, and multiple hoses are laid in the second pipe placement grooves 243 on the first pipe cutter 2 and the second pipe cutter 3, and the cylinders 2 on the first pipe cutter 2 and the second pipe cutter 3 are started at the same time. 2. The output end of the cylinder 22 drives the lower pressing plate 25 to fall, the tube cutting assembly 27 is connected to the workbench 24, and the cutter seat 273 enters the positioning groove 244 to fix the hoses on the first tube cutting machine 2 and the second tube cutting machine 3. The lower pressing plate 25 continues to move downward, driving the tube cutting assembly 27 to continue to move, and the cutting blade 274 cuts the hose. After the cutting blade 274 contacts the cutting blade pad 29, the hose is completely cut off. The cylinder 22 is started again to drive the tube cutting assembly 27 to reset, and the cutter seat 273 is separated from the positioning groove 244, releasing the limit on the hose, and the cut hose can be removed;

[0034] S3, when cutting hoses of different lengths, after the position adjustment of the second pipe cutter 3 is completed, the cylinder 22 on the first pipe cutter 2 is controlled to start, so that the pipe cutting assembly 27 on the first pipe cutter 2 is connected to the workbench 24, and the hose is abutted against the cutting blade 274 on the first pipe cutter 2. The second pipe cutter 3 is driven normally to cut the hose in a fixed manner, and a hose of a set length can also be obtained;

[0035] S4. When cutting hoses of different lengths, after adjusting the position of the second pipe cutting machine 3, place the end of the hose against the positioning block 28 on the first pipe cutting machine 2, and repeat the above steps to control the first pipe cutting machine 2 and the second pipe cutting machine 3 to cut the hose, so that hoses of two sizes can be obtained.

[0036] It should be noted that there is a certain amount of waste in step S2. The hose on the first tube cutting machine 2 needs to be of a certain length so that the tube cutting assembly 27 is connected to the workbench 24 and the hose on the first tube cutting machine 2 is fixed. After cutting, the length of the hose on the first tube cutting machine 2 is relatively small and cannot be used any more, resulting in waste. There is a certain amount of error in step S3. The hose is not placed in the second tube placing groove 243, and the hose abutting against the cutting blade 274 may have a certain angle error with the hose in the second tube placing groove 243.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
