[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. The following describes each embodiment of the present invention in detail with reference to the drawings.

[0022] Please refer to Figures 1 to 6 , the present invention preferably provides a technical solution: a punching device for sheet metal parts, including: a machine body 1, which is composed of a bracket 101, and support plates 102 and supports 103 on the upper and lower parts of the bracket 101; several electric telescopic rods 2 are arranged at the bottom of the support plate 102, and a transmission table 3 is fixed to the telescopic ends of the several electric telescopic rods 2; it also includes a stamping assembly 5 and a cutting assembly 6 arranged in the middle of the transmission table 3 and distributed inside and outside, and the stamping assembly 5 and the cutting assembly 6 are respectively used for punching the sheet metal workpiece and the pre-cutting process before punching; several bracing column assemblies 4 are also arranged at the bottom of the transmission table 3, and the several bracing column assemblies 4 are annularly distributed on the outer periphery of the cutting assembly 6 and serve as a fixing structure before the pre-cutting of the sheet metal workpiece.

[0023] From Figure 1 , 2 , it can be seen that the support plate 102 and the support 103 are respectively arranged on the upper and lower parts of the bracket 101, and the support plate 102 is used for placing the sheet metal workpiece, while the electric telescopic rods 2, the transmission table 3, the stamping assembly 5, the cutting assembly 6 and several bracing column assemblies 4 arranged below the support 103 are used for the punching work of the sheet metal workpiece;

[0024] Specifically: the transmission table 3 is fixedly installed at the telescopic end of the electric telescopic rod 2, the stamping assembly 5 and the cutting assembly 6 are installed in the middle of the transmission table 3 in an inside-out distribution form and are respectively used for punching the sheet metal workpiece and the pre-cutting process before punching; and several bracing column assemblies 4 are arranged at the bottom of the transmission table 3 in an annular distribution form and are distributed on the outer periphery of the cutting assembly 6 to realize the fixation before the pre-cutting of the sheet metal workpiece. Combining Figure 2As shown in the figure, when punching the sheet metal workpiece is required, first drive the electric telescopic rod 2 to operate so that several abutting column assemblies 4 abut against and fix the outer periphery of the punching site of the sheet metal workpiece. Subsequently, operate the cutting assembly 6 to achieve the pre-cutting process before punching the sheet metal workpiece. This process ensures the punching quality while improving the punching efficiency. Then drive the stamping assembly 5. Since the stamping assembly 5 and the cutting assembly 6 are distributed inside and outside, the stamping assembly 5 can stamp the sheet metal scraps within the cutting line, thus completing the punching process of the sheet metal workpiece;

[0025] In the present utility model, through the stamping assembly 5 and the cutting assembly 6 distributed inside and outside, combined with the abutting column assemblies 4 arranged on the outer peripheries of the two, on the premise of fixing the outer periphery of the punching point of the sheet metal workpiece, the pre-cutting and punching processes of the sheet metal workpiece are completed in sequence. This design not only ensures the punching quality but also significantly improves the punching efficiency.

[0026] Furthermore, the cutting assembly 6 includes a transmission sleeve 601 rotatably connected to the middle of the transmission table 3, and a cutting tool 602 detachably installed at the bottom of the transmission sleeve 601; it also includes an engagement driving assembly 7 arranged on the transmission table 3, and the engagement driving assembly 7 is used to drive the transmission sleeve 601 to rotate.

[0027] As Figure 2 、 6 shown, here for the transmission sleeve 601, its bottom end is detachably installed with the cutting tool 602, and its top end rotates by the power provided by the engagement driving assembly 7. Thus, when the entire transmission table 3 moves downward, the rotating cutting tool 602 can perform a pre-cutting operation on the punching site of the sheet metal workpiece. It should be noted that here the cutting tool 602 is preferably in a circular hollow shape;

[0028] In addition, since the cutting tool 602 is detachably installed with the transmission sleeve 601, it is further convenient to change the model of the cutting tool 602.

[0029] Furthermore, the engagement driving assembly 7 includes a first transmission gear 701 fixed to the side wall near the top of the transmission sleeve 601, and a motor 703 arranged on the transmission table 3, and a second transmission gear 702 fixed to the output end of the motor 703 meshes with the first transmission gear 701.

[0030] Since the first transmission gear 701 meshes with the second transmission gear 702, as Figure 2 shown, when the motor 703 operates, the rotation process of the transmission sleeve 601 and the cutting tool 602 can be realized.

[0031] Further, the stamping assembly 5 includes a hydraulic telescopic cylinder 501 disposed on the top of the support 103, and a stamping column 502 penetratingly installed in the middle of the support 103. One end of the stamping column 502 is connected to the output end of the hydraulic telescopic cylinder 501, and the other end thereof sequentially penetrates the inside of the transmission sleeve 601 and the cutting tool 602 downward.

[0032] Here, the hydraulic telescopic cylinder 501 penetratingly installed in the middle of the support 103, one end thereof is connected to the hydraulic telescopic cylinder 501, and the other end thereof sequentially penetrates the inside of the transmission sleeve 601 and the cutting tool 602. Therefore, after the cutting assembly 6 completes the pre-cutting, at this time, driving the hydraulic telescopic cylinder 501 to operate can cause the stamping column 502 to press the sheet metal scraps within the cutting line downward and separate them from the sheet metal workpiece.

[0033] Further, each set of abutting column assemblies 4 includes a telescopic structure 401, which is composed of a telescopic rod, a telescopic sleeve and a spring between the two. One end of the telescopic rod away from the telescopic sleeve is connected to the bottom of the transmission table 3; it also includes a support pad 402, and the support pad 402 is disposed at the bottom end of the telescopic sleeve.

[0034] It is known that, as Figure 1 、 2 、shown in 5, the telescopic structure 401 is a mature existing technology. One end of its telescopic rod is connected to the bottom of the transmission table 3, and the other end is connected to the inner bottom of the telescopic sleeve through a spring. And a support pad 402 is disposed at the bottom end of the telescopic sleeve. Therefore, when the electric telescopic rod 2 extends and causes the transmission table 3 and several abutting column assemblies 4 on the transmission table 3 to move downward as a whole, at this time, the support pad 402 can abut against and fix the outer periphery of the punching point of the sheet metal workpiece, thereby realizing the fixing process before the sheet metal workpiece is processed.

[0035] Further, the support pad 402 is made of elastic rubber material to improve the fixing effect of the abutting column assembly 4 on the sheet metal workpiece.

[0036] Further, the support plate 102 includes a seat body and a groove body formed on the seat body, and the groove body is composed of a placement groove in the upper part of the seat body and a through groove in the lower part of the seat body.

[0037] Here, in combination with the shape of the groove body as Figure 5 shown, the placement groove where the groove body is located is used for placing the sheet metal workpiece, and the through groove below the placement groove provides an operating space for the downward pressing of the stamping assembly 5.

[0038] In the present utility model, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", "fixation" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated. There are various detachable installation methods. For example, it can be by means of cooperation of plugging and buckling, or by means of bolt connection and the like.

[0039] The specific description of the present utility model in the above embodiments is only used for further illustration of the present utility model, and should not be construed as a limitation on the protection scope of the present utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the content of the above utility model fall within the protection scope of the present utility model.
