[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 carrier of PTC heating elements. When square aluminum tubes are processed as heater accessories, they are usually cut by a cylinder-driven cutting knife as required. Although this can also complete the cutting of square aluminum tubes, the cutting is not stable, which affects the cutting quality. Utility Model Content

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0018] Combination Figure 1-3As shown, the square aluminum tube cutting and unloading device includes a machine table 1, a movable frame 2 is provided on the machine table 1, a cutting cylinder 3 is provided on the top of the movable frame 2, a cutting seat 4 is provided on the bottom, an upper cover 5 is provided on the cutting seat 4, a notch 6 is provided inwardly on the cutting seat 4, a mounting seat 8 is provided on the driving shaft of the cutting cylinder 3, a pair of reinforcing plates 10 are provided on both sides of the mounting seat 8, a cutting knife 9 is provided downwardly on the mounting seat 8, and both ends of the cutting knife 9 are installed in the reinforcing plate 10 on the same side, a guide opening 11 is provided at the bottom of the reinforcing plate 10 and on the side wall of the cutting knife 9, a guide plate 12 is provided in the notch 6, and the guide plate 12 is arranged toward the two guide openings 11, and a unloading mechanism is also provided on the machine table 1 at the rear side of the cutting seat.

[0019] PTC heaters usually use square aluminum tubes as the mounting carrier of PTC heating elements, and the square aluminum tubes are used as heater accessories. During processing, the device can be used to cut a long square aluminum tube as a raw material into several sections of fixed-length square aluminum tubes according to requirements.

[0020] When using the device to cut a square aluminum tube, first a long square aluminum tube is fed through the feeding mechanism. At this time, the square aluminum tube is located on the cutting seat, and the other end of the square aluminum tube passes through the upper cover and is located on the unloading mechanism. During cutting, the cutting cylinder drives the mounting seat to move toward the cutting seat, and at this time the cutting knife moves toward the square aluminum tube until the square aluminum tube is cut. The cut square aluminum tube section is unloaded through the unloading mechanism. The feeding mechanism is not the focus of the device, so it will not be described here.

[0021] In the present structure, the cutting edge of the cutting knife is located in the guide opening; and the cutting knife and the guide plate are arranged alternately. The length of the guide plate matches the distance between the two guide openings. When cutting the square aluminum tube, the cutting knife first penetrates into the upper cover, and then the bottoms of the two reinforcing plates are respectively in contact with the two ends of the guide plate, that is, the two ends of the guide plate are respectively inserted into the guide opening of the same end, and the cutting edge of the cutting knife is in contact with the square aluminum tube. Then the cutting knife continues to move downward until the cutting of the square aluminum tube is completed. During the cutting process, the two ends of the guide plate slide in the two guide openings respectively. During the entire cutting process, the guide plate also plays the role of guiding and limiting the cutting knife block. At the same time, the guide plate supports the cutting position of the square aluminum tube, making the entire cutting process more stable and improving the cutting quality.

[0022] The inner side of the reinforcing plate is provided with an installation groove, and the side wall of the knife block is installed in the installation groove. The reinforcing plate can make the knife block more stably installed, and further improve the cutting quality.

[0023] In actual situations, Figure 3The movable frame 2 is slidably mounted on the machine table 1, and the movable frame 2 is moved by the movable module 13 to change the cutting position of the square aluminum tube. As a preferred structure, the movable module 13 may include a movable frame 131, and a screw rod (blocked in the figure) is rotatably arranged inside the movable frame 131, and a screw rod sleeve is sleeved on the screw rod, and the screw rod sleeve is connected to the movable frame 131 through a connecting plate 132, and a movable motor 133 for driving the screw rod to rotate is also arranged on the machine table.

[0024] When the moving frame needs to be moved by the moving module to change its cutting position, the moving motor drives the screw to rotate, and the screw sleeve moves along the length direction of the screw, thereby driving the moving frame to slide on the machine table.

[0025] In this device, if Figure 1-2 The unloading mechanism includes a carrier plate 14 mounted on a moving frame 2, an upper moving wheel 15 and a lower moving wheel 16 are rotatably provided on the moving frame 2 and the carrier plate 14, a rotatable driving wheel 17 is provided on the machine 1, a front pulley 18 and a rear pulley 19 are rotatably provided inside the machine 1, and an unloading belt 20 is wound around the upper moving wheel 15, the lower moving wheel 16, the front pulley 18, the rear pulley 19, and the driving wheel. A driving motor 21 for driving the driving wheel to rotate is provided on the machine. The upper moving wheel is located inside the unloading belt, and the lower moving wheel is located outside the unloading belt.

[0026] The cut square aluminum tube segments fall onto the unloading belt and can be unloaded under the conveyor. In this structure, when the moving frame moves under the action of the moving module, the upper moving wheel and the lower moving wheel move in the same direction. For example, when the moving frame moves backward, the upper moving wheel moves in the unloading belt, and the lower moving wheel pushes the unloading belt to pre-tighten it, so that the unloading belt can rotate stably.

[0027] The cutting seat is inwardly recessed to form an escape space, and the upper moving wheel is rotatably installed in the escape space. In this way, the blanking belt can be arranged close to the cutting seat, and the cut square aluminum tube section can always be located on the blanking belt.

[0028] Further as a priority structure, such as Figure 1 The machine 1 is provided with a support frame 22 , and the support frame 22 is provided with a pair of slot plates 23 , the two slot plates 23 are located on both sides of the unloading belt 20 , and the outlet of the upper cover 5 is provided with a guide cover 24 , and the guide cover 24 is located in the two slot plates 23 .

[0029] The support frame is used as a carrier for installing the slot plate. The two slot plates can play a guiding role to prevent the square aluminum tube segment from falling off the blanking belt. When the moving frame is moving, the guide cover moves synchronously in the two slot plates. At this time, the two slot plates play a role in limiting and guiding the guide cover. The guide cover plays a role in limiting the upper and lower positions of the square aluminum tube in cooperation with the blanking belt, further improving the cutting quality.

[0030] In addition, a hanging plate 25 is provided between the mobile frame 2 and the guide cover 24. This can make the guide cover more stably installed.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
