It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0027] like Figure 1 As shown, on the one hand, an embodiment of the present application provides a side cutting tool 1, which includes a handle 11 and a blade 12, which can effectively reduce the sticking problem of aluminum chips, thereby improving the service life and side cutting quality of the side cutting tool 1.

[0028] The handle 11 is used for clamping and mounting on a machining device, and the blade 12 is used for cutting a frame member such as an aluminum alloy middle frame. The blade 12 has a front edge surface 121 and a base surface 122 arranged adjacent to each other, the front edge surface 121 connects the handle 11 and the base surface 122, and the connection between the front edge surface 121 and the base surface 122 forms a relatively sharp blade tip.

[0029] The angle between the front blade surface 121 and the base surface 122 is set to 72° to 78°, which can be, for example, 72°, 72.5°, 73°, 73.5°, 74°, 75°, 75.5°, 76°, 77°77.5° or 78°. When the side cutting tool 1 provided in the embodiment of the present application is used to side cut a frame member such as an aluminum alloy middle frame, the blade 12 is located below the handle 11, and the front blade surface 121 faces the part to be side cut on the frame member, and the tip of the blade is used to cut the part to be side cut; in this process, the aluminum powder generated by cutting can be discharged relatively easily and is not easy to stick to the blade 12, which can effectively reduce the sticking problem of aluminum chips, thereby improving the service life and side cutting quality of the side cutting tool 1.

[0030] In some embodiments, the connection between the front blade surface 121 and the handle 11 can form a rounded corner 123. By setting the connection between the front blade surface 121 and the handle 11 as the rounded corner 123, the rounded corner 123 can be used to achieve a smooth transition between the front blade surface 121 and the handle 11, reduce the stress concentration between the front blade surface 121 and the handle 11, and thus improve the connection strength between the front blade surface 121 and the handle 11; when the side cutting tool 1 is used to side cut the frame, it can avoid accidental fracture between the blade 12 and the handle 11 due to stress concentration, thereby increasing the stability and reliability of the side cutting process, thereby improving the side cutting quality.

[0031] In some embodiments, the side surface of the blade 12 connected to the front edge 121 and the base surface 122 can be arranged in parallel. In this way, the angle between the side surface of the blade 12 connected to the front edge 121 and the front edge 121 is also 72° to 78°, so that a relatively wide chip removal space is formed between the two, so that the aluminum powder generated by cutting can be discharged more easily and is not easy to stick to the blade 12, effectively reducing the sticking problem of aluminum chips.

[0032] In some embodiments, the outer diameter of the handle 11 may be greater than the outer diameter of the blade 12. In other words, the handle 11 is thicker and the blade 12 is thinner, so that the handle 11 and the side cutting tool 1 have a higher structural strength; thus, when the handle 11 is clamped and installed on a machining device, the handle 11 can form a more reliable connection with the machining device, thereby increasing the overall strength of the side cutting tool 1 when performing side cutting, thereby improving the service life of the side cutting tool 1.

[0033] like Figure 1 and Figure 2 As shown, on the other hand, an embodiment of the present application provides a frame punching device, which includes a punching die 2 and a side cutting tool 1 of any of the above embodiments, and the side cutting tool 1 is arranged on the punching die 2. Since the frame punching device has the above side cutting tool 1, the sticking problem of aluminum chips can be effectively reduced, thereby improving the service life and side cutting quality of the side cutting tool 1.

[0034] The structure of the punching die 2 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the side cutting direction of the side cutting tool 1 and the opening and closing direction of the punching die 2 are arranged vertically. Here, the punching die 2 may include an upper die 21, a stopper middle die 22, and a lower die 23 arranged sequentially from top to bottom. The upper die 21, the stopper middle die 22, and the lower die 23 can be closed or opened in sequence along the up and down direction, and the frame can be side cut when the punching die 2 is closed.

[0035] Here, the upper die 21 may be provided with a side sliding drive member 214, and the side cutting tool 1 may be slidably arranged on the stopper middle die 22 in the horizontal direction, and the side sliding drive member 214 is used to drive the side cutting tool 1 to slide horizontally; and the workpiece mounting groove may be opened on the upper surface of the lower die 23, for embedding the frame to be side cut. When the upper die 21 and the middle die are separated, the side sliding drive member 214 and the side cutting tool 1 remain separated, and at this time, the side sliding drive member 214 does not apply a sliding driving force to the side cutting tool 1. When the upper die 21 moves downward to make the upper die 21, the stopper middle die 22 and the lower die 23 engage in sequence, the side cutting tool 1 is gradually embedded in the workpiece mounting groove, and the side sliding drive member 214 contacts the side cutting tool 1 downwardly, and the side sliding drive member 214 further moves downward to drive the side cutting tool 1 to slide in the horizontal direction, so as to convert the movement in the up-down direction into the movement in the horizontal direction, so that the side cutting tool 1 slides horizontally to punch the frame in the workpiece mounting groove, thereby achieving the purpose of side cutting.

[0036] like Figure 3 and Figure 4 As shown, in some examples, a punching tool 215 may be provided on the upper die 21 to achieve the purpose of downward punching. When the upper die 21 moves downward to make the upper die 21, the stopper middle die 22 and the lower die 23 engage in sequence, the punching tool 215 moves downward through the stopper middle die 22 to punch the frame in the workpiece mounting groove. In this way, the frame punching device can realize the functions of downward punching and horizontal side cutting; when the punching die 2 is closed, different parts of the frame in the workpiece mounting groove can be punched downward and horizontally cut at the same time, and the frame can be processed in one piece through the same process step, thereby reducing the process steps for punching the aluminum alloy middle frame, saving processing time and processing costs.

[0037] The structure of the upper die 21 can be determined according to actual needs, and can have an integral structure or a split structure, which is not limited in the present embodiment. In some examples, the upper die 21 can include an upper die seat 211, an upper pad 212, and an upper clamping plate 213 stacked in sequence from top to bottom, and the punching tool 215 and the side sliding driving member 214 can be respectively embedded in the upper clamping plate 213 and then abut against the upper pad 212.

[0038] In some examples, the stopper middle mold 22 may also be provided with an elastic reset member, which is elastically deformed and connected to the side cutting tool 1 in the horizontal direction. When the side sliding driving member 214 and the side cutting tool 1 are separated, the elastic reset member causes the side cutting tool 1 to slide and reset in the horizontal direction, so that the side cutting tool 1 automatically returns to the initial position after the punching mold 2 is separated.

[0039] In some examples, the stopper mold 22 may be provided with a through hole 223, which passes through the stopper mold 22 in the up-down direction. The handle 11 of the side cutting tool 1 may be slidably disposed in the through hole 223 in the horizontal direction, and the blade 12 of the side cutting tool 1 extends to the side of the stopper mold 22 away from the upper mold 21. In this way, when the stopper mold 22 and the lower mold 23 are engaged and molded, the blade 12 may protrude from the stopper mold 22 and be embedded in the workpiece mounting groove, thereby performing side cutting on the frame member in the workpiece mounting groove, thereby ensuring the side cutting function.

[0040] The structure of the stopper middle mold 22 can be determined according to actual needs, and can have an integral structure or a split structure, which is not limited in the embodiments of the present application. In some examples, the stopper middle mold 22 may include a stopper plate 221 and an upper stripping plate 222 stacked in sequence from top to bottom, and the side cutting tool 1 may be slidably arranged on the upper stripping plate 222 in a horizontal direction. Here, the through hole 223 may pass through the stopper plate 221 and the upper stripping plate 222 in sequence; or, the through hole 223 may be arranged through the upper stripping plate 222, and a avoidance portion may be provided on the stopper plate 221, and the avoidance portion and the through hole 223 are arranged correspondingly.

[0041] The structure of the lower mold 23 can be determined according to actual needs, and can have an integrated structure or a split structure, which is not limited in the embodiments of the present application. In some examples, the lower mold 23 can include a lower mold plate 231, a lower pad 232, and a lower mold base 233 stacked in sequence from top to bottom, and the workpiece mounting groove can be opened on the upper surface of the lower mold plate 231.

[0042] The driving mode of the side-sliding driving member 214 on the side-cutting tool 1 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some examples, the side-sliding driving member 214 can be provided with a first sliding inclined surface 2141, and the handle 11 can be provided with a second sliding inclined surface 111. The first sliding inclined surface 2141 and the second sliding inclined surface 111 are arranged in parallel, and the first sliding inclined surface 2141 and the horizontal plane are arranged obliquely. Here, the first sliding inclined surface 2141 can be arranged at the lower corner area of ​​the side-sliding driving member 214, and the second sliding inclined surface 111 can be arranged at the upper corner area of ​​the side-cutting tool 1; when the first sliding inclined surface 2141 and the second sliding inclined surface 111 are fitted and connected, the side-sliding driving member 214 can move downward to drive the side-cutting tool 1 to slide in the horizontal direction, and the movement in the up-down direction is converted into the movement in the horizontal direction by using the matching relationship between the first sliding inclined surface 2141 and the second sliding inclined surface 111, so as to achieve the purpose of side-cutting in the horizontal direction. When a punching tool 215 is also provided on the upper mold 21, downward punching and horizontal side cutting of different parts on the frame can be achieved at the same time through the clamping process of the punching mold 2, so that the punching tool 215 can move downward and the side cutting tool 1 can slide horizontally, saving processing time and processing costs.
