[0002] In the field of new energy vehicle technology, electric vehicles generally use power battery packs as a power source. Unlike fuel engines, electric vehicles do not have a power device that generates heat sources, and cannot provide heat sources to power battery packs. At the same time, they cannot provide the warm air heat source required for air conditioning, defrosting, etc. Therefore, electric vehicles must rely on electricity to use PTC heaters for heating.

[0003] PTC heaters usually use square aluminum tubes as the installation carriers of PTC heating elements. When square aluminum tubes are processed as heater accessories, they usually need to be cut into suitable lengths. However, when existing cutting machines perform continuous cutting on square tubes, a movable push plate is usually set at one end of the tube to push the tube forward for cutting. If the tube is long, the push plate has poor stability when pushing the tube to move, thereby affecting the cutting accuracy. Therefore, a square tube cutting machine with automatic feeding is proposed to solve the above problems. Utility Model Content

Under the action of the horizontal linear module 201 and the auxiliary linear module 306, the position of the square tube can be flexibly adjusted, so as to accurately control the cutting position of the square tube. After moving the square tube to the appropriate position, the left positioning cylinder 304 retracts, and the left positioning plate 303 presses the square tube on the corresponding positioning seat 301, and the right positioning seat 301 returns to the initial position and clamps the square tube again, so that the square tube can be stably clamped under the cutting knife 405;

[0040] The output shaft of the driving motor 407 drives the worm 408 to rotate, and the worm wheel 409 meshing with the worm 408 drives the cutting shaft 404 to rotate, thereby driving the cutting knife 405 to rotate, and the driving cylinder 402 is pushed out to drive the cutting knife 405 to move down, so as to cut the square tube;

[0041] The cut square tube is introduced into the finished product collection box 504 through the sloped guide trough 501 and the blanking trough 502 for collection, and then fed to the right through the horizontal linear module 201 and the auxiliary linear module 306 and transported to the appropriate position. The above operation is repeated to continue cutting.
