[0024] Embodiment 1, see Figures 1 - 7The present embodiment provides a cutting device for processing metal shells of electronic products, including a double-layer support frame 1, the double-layer support frame 1 is divided into an upper support seat and a lower support seat, the upper support seat and the lower support seat are fixed by four groups of support legs, the upper top of the double-layer support frame 1 is fixedly connected with an L-shaped support plate 4, the L-shaped support plate 4 is equipped with an electric telescopic rod 6 connected to the motor, the motor is fixedly connected to the top of the electric telescopic rod 6, an annular placement table is placed on the upper top of the double-layer support frame 1 for placing the metal shell to be cut, the telescopic end of the electric telescopic rod 6 is fixedly connected with a cutting knife 7, the outer side of the electric telescopic rod 6 is fixedly connected with a bevel gear 1 101, due to the meshing between the bevel gear 101 and the bevel gear 2 102 This can make the rotating rod 103 also be able to rotate. The side of the L-shaped support plate 4 is rotatably connected to the rotating rod 103, and the outer side of the rotating rod 103 is fixedly connected to the bevel gear 2 102. The top of the lower layer of the double-layer support frame 1 is fixedly connected to the support plate 113. The function of the support plate 113 is to support the rotating movement of the support rod 105, thereby facilitating the use of the support rod 105. The inside of the support plate 113 is rotatably connected to the support rod 105. The upper layer of the double-layer support frame 1 is penetrated and fixedly connected with the air cylinder 106. The top of the air cylinder 106 is provided with nine groups of air extraction holes, and the middle position of the metal shell that needs to be cut is placed on the top of the nine groups of air extraction holes. The inside of the air cylinder 106 is slidably connected to the piston rod 107, and the top of the piston rod 107 The end is made of rubber material, the bottom end of the piston rod 107 is fixedly connected to a fixed frame 108, the interior of the fixed frame 108 is slidably connected to a sliding plate 109, the bottom end of the sliding plate 109 is fixedly connected to a tension rope 112, and the end of the tension rope 112 away from the sliding plate 109 is fixedly connected to a winding disk 114, and the winding disk 114 can reel in the tension rope 112 when rotating, so that the piston rod 107 can be pulled, so that the air cylinder 106 can inhale and fix the metal shell to be cut, and the interior of the winding disk 114 passes through and is fixedly connected to a limit rod 116, which is located on the motion trajectory of the support rod 105, and the top of the lower layer of the double-layer support frame 1 is fixedly connected to a square frame 115, and the double-layer support frame The top of the upper layer of the double-layer support frame 1 is equipped with a placement component 8 for automatically placing the cut items. A circular groove is opened on the side of the square frame 115, and three groups of limiting holes 117 are opened inside the circular groove. In the initial state, the spring 2 is in a compressed state. The top of the upper layer of the double-layer support frame 1 is equipped with a buffer component 9 for protecting the cut items when they fall. The support rod 105 and the rotating rod 103 are connected by a conveyor belt 104. The support rod 105 and the rotating rod 103 are connected by a conveyor belt 104. Therefore, when the rotating rod 103 rotates, the support rod 105 can follow and rotate synchronously. A spring 110 is elastically connected between the top of the sliding plate 109 and the bottom of the fixed frame 108.The other end of the limiting rod 116 away from the winding disc 114 is elastically connected with a limiting ball 118 through a second spring. The first bevel gear 101 meshes with the second bevel gear 102. Limiting holes 117 are formed inside the side surface of the square frame 115. There are three groups of the limiting holes 117, and the specifications and sizes of the three groups of limiting holes 117 are adapted to those of the limiting ball 118.,

[0025] During use, people first need to move the device to a position suitable for the use of the device. First, the staff place the metal shell to be cut on the annular placing table, and then start the switch of the motor, so that the output shaft of the motor can drive the electric telescopic rod 6 to rotate. At the same time, when the telescopic end of the electric telescopic rod 6 drives the cutting knife 7 to cut the metal shell, the height position is adjusted, and at the same time, it rotates and cuts under the action of the motor. At the same time, when the electric telescopic rod 6 rotates, the first bevel gear 101 can rotate synchronously, so that the second bevel gear 102 rotates, and at the same time drives the rotating rod 103 to rotate. Under the action of the conveyor belt 104, the support rod 105 can also rotate. When the support rod 105 rotates, during the rotation of the small vertical rod on the outer side of the support rod 105, the limiting rod 116 can be extruded, so that the limiting rod 116 drives the winding disc 114 to rotate. When the winding disc 114 rotates, the pulling rope 112 can be pulled downward. When the pulling rope 112 is pulled downward, the sliding plate 109 can be pulled downward synchronously. At the same time, when the sliding plate 109 moves downward, the first spring 110 can be elastically compressed, and the fixed frame 108 can also move downward synchronously. When the fixed frame 108 moves downward, the piston rod 107 can move downward from top to bottom inside the air cylinder 106, so that the hole formed at the top of the air cylinder 106 generates suction, and the metal shell placed at the top of the air cylinder 106 can be fixed, which is convenient for the cutting knife 7 to perform the cutting work. And when the limiting rod 116 rotates, it can slide inside the circular groove. When sliding a certain distance, the limiting ball 118 on the limiting rod 116 can be correspondingly clamped with the limiting hole 117, so as to limit the further rotation of the limiting rod 116. When the metal shell to be fixed is larger, the limiting rod 116 can be rotated again by rotating the support rod 105 again, so that the limiting ball 118 on the limiting rod 116 is clamped with the second group of limiting holes 117. In this way, the pulling distance of the piston rod 107 can be adjusted, and then the suction of the air cylinder 106 can be adjusted to adapt to metal shells of different specifications and sizes.,

[0026] Example 2, see Figures 1 - 10, on the basis of Embodiment 1, in the present application, there are two groups. Two L-shaped connecting rods 801 are respectively fixedly connected to both sides of the bottom end of the piston rod 107. The top ends of the two L-shaped connecting rods 801 are both fixedly connected with lifting plates 803. The function of the two L-shaped connecting rods 801 is to link the movement of the two lifting plates 803 with the movement of the piston rod 107, so that the two lifting plates 803 change following the movement of the two piston rods 107. The upper layer top end of the double-layer support frame 1 is fixedly connected with a support frame 806. The function of the support frame 806 is to support the use of the first hydraulic cylinder 807, thus facilitating the use of the first hydraulic cylinder 807. The first hydraulic cylinder 807 is penetrated and fixedly connected inside the support frame 806. One end inside the first hydraulic cylinder 807 is slidably connected with a pressure rod 808 through a piston. The extending end of the pressure rod 808 is fixedly connected with a push plate 805. The function of the push plate 805 is to push the cut metal shell, so that the metal shell is pushed into the storage box 809. The other end inside the first hydraulic cylinder 807 is slidably connected with two stress rods 804 through a piston. The upper layer bottom end of the double-layer support frame 1 is fixedly connected with a storage box 809 through bolts. The storage box 809 is used to store the cut metal shells. The two stress rods 804 are respectively located on the movement tracks of the two lifting plates 803.

[0027] During use, on the basis of Embodiment 1, when the piston rod 107 slides upward inside the air cylinder 106, at this time, the fixation of the metal shell to be cut is cancelled. At the same time, during the upward sliding movement of the piston rod 107, it can drive the two L-shaped connecting rods 801 to slide upward synchronously. Furthermore, it can make the two L-shaped connecting rods 801 drive the two lifting plates 803 to slide upward synchronously. When the two lifting plates 803 slide upward, they can jack up the cut metal shell upward, so that the position of the metal shell can be flush with the push plate 805. And when the two lifting plates 803 slide upward, they can synchronously squeeze the two stress rods 804. When the two stress rods 804 receive the squeezing force, at this time, the liquid pressure inside the first hydraulic cylinder 807 increases, so that the pressure rod 808 can be pushed out, and further the push plate 805 can be driven to be pushed out synchronously, and the cut metal shell can be pushed into the storage box 809 along the direction of the push plate 805, thus reducing the participation of the staff and reducing the labor of the staff.

[0028] Embodiment 3, see Figures 1 - 11, on the basis of Embodiment 1, in the present application, the buffer assembly 9 includes a first switch door 905. One side of the first switch door 905 is hinged to the top end of the storage box 809. The other side of the first switch door 905 is elastically connected with a second switch door 906 through a torsion spring. The upper layer top end of the double-layer support frame 1 is fixedly connected with a second hydraulic cylinder 903. One end inside the second hydraulic cylinder 903 is slidably connected with a second force-bearing rod 902 through a piston. The protruding end of the second force-bearing rod 902 is equipped with a spherical structure. The other end inside the second hydraulic cylinder 903 is slidably connected with a second pressure rod 904 through a piston. When the second force-bearing rod 902 is subjected to an extrusion force, at this time, the internal liquid pressure of the second hydraulic cylinder 903 increases, so that the first pressure rod 808 can be pushed out. The side of the first pressure rod 808 is fixedly connected with an L-shaped extrusion rod 907. One end of the L-shaped extrusion rod 907 away from the first pressure rod 808 is equipped with a spherical structure. The second force-bearing rod 902 is located on the movement track of the L-shaped extrusion rod 907.

[0029] During use, on the basis of Embodiment 1, when the cut metal shell is pushed into the interior of the storage box 809 by the push plate 805, at this time, the L-shaped extrusion rod 907 on the side of the push plate 805 can squeeze the second force-bearing rod 902, making the internal liquid pressure of the second hydraulic cylinder 903 increase, and the second pressure rod 904 can be pushed out, so that the second pressure rod 904 can act on the first switch door 905, making the first switch door 905 and the second switch door 906 in an inclined state at the hinge. At the same time, when the metal shell further drops, the second switch door 906 is in a vertical state, so that there is a buffering force when the metal shell pushed into the interior of the storage box 809 is pushed into the interior of the storage box 809, and thus the metal shell can be protected.

[0030] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
