Advantage of the utility model:

The utility model can carry out continuous operation. When in use, firstly, the sleeve to be cut is inserted into the middle of the four guide turntables of the transmission mechanism, and the sleeve is driven forward at a uniform speed under the extrusion of the guide turntables on both sides; secondly , while the casing is being transported, the fixed seat of the cutting mechanism will move to the left under the drive of the hydraulic cylinder. When the bump of the fixed seat touches the second travel switch, the plc programmable controller will stop the driving motor , and make the cutting motor start, at this time the clamping block and the guide block can just clamp the casing to avoid shaking of the casing during cutting; when the fixed seat continues to move to the left and touches the third travel switch, the plc The programmable controller will stop the cutting motor and reset the hydraulic cylinder, and the fixed seat will start to move to the right; since the bump on the fixed seat will always keep in contact with it after touching the second travel switch, until the fixed seat moves to the right Therefore, in each working cycle, the second travel switch will only trigger one action; when the fixed seat touches the first travel switch, the plc programmable controller will start the driving motor to continue to transmit the bushing, and make the hydraulic pressure The cylinder stretches out and enters the next working cycle. The utility model not only can realize continuous operation, but also can stabilize the sleeve pipe during cutting, so as to realize precise cutting.
