Description

Technical Field

[0001] The utility model relates to the technical field of punching, and more particularly to a punching device suitable for metal products. Background Art

[0002] Punching is a metalworking or sheet metal forming process that utilizes a punch press and die to apply pressure to the sheet, forcing the punch on the die to penetrate the material, thereby creating a hole of the desired shape and size. This technology is widely used in the manufacturing industry, including automotive, electronic equipment housings, building components, household appliances, decorative parts, and other fields. It enables efficient and precise mass production while ensuring product quality and consistency. Punching not only improves production efficiency but also reduces material waste, making it an indispensable and important technology in modern industrial production.

[0003] However, when punching a rectangular metal frame, the existing punching device mostly directly applies pressure to the entire metal frame, which can easily cause the metal frame to be compressed and deformed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a punching device suitable for metal products.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a punching device suitable for metal products, comprising a base, a support frame fixedly connected to the base, a hydraulic cylinder mounted on the support frame, a punch fixedly connected to the piston rod of the hydraulic cylinder, a base fixedly connected to the support frame, a bump fixedly connected to the base, a support arm fixedly connected to the bump, a through slot formed on the support arm, and the punch aligned with the through slot;

[0006] Use the support arm to support the side wall of the metal frame that needs to be punched. When punching, the punch penetrates the side wall of the metal frame and extends into the through groove. The support arm supports the punching position to prevent the entire metal frame from bearing the downward pressure from the punch, thereby preventing the metal frame from deformation.

[0007] Preferably, a cross bar is fixedly connected to the protrusion, an indicator hole is opened at one end of the cross bar, and the punch is aligned with the indicator hole.

[0008] Preferably, a bidirectional screw rod is rotatably connected to the base, and auxiliary arms are respectively threadedly connected to both ends of the bidirectional screw rod. Both auxiliary arms are slidably connected to the guide rod, and the guide rod is fixedly connected to the base.

[0009] Preferably, one end of the bidirectional screw rod is fixedly connected to a handle.

[0010] Preferably, a slide is fixedly connected to the support arm, the through groove is communicated with the slide, one end of the slide is communicated with the material box, and the material box is placed on the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Use the supporting arm to support the side wall of the metal frame where the punching is required. When punching, the punch penetrates the side wall of the metal frame and extends into the through slot. The supporting arm supports the punching position to prevent the metal frame from bearing the downward pressure from the punch, thereby preventing the metal frame from deformation.

[0013] 2. Multiple auxiliary arms cooperate with the supporting arms to support the metal frame, making it more stable. By rotating the bidirectional screw, the two auxiliary arms can be driven to move in opposite directions along the guide rod, thereby adjusting the distance between the two auxiliary arms to adapt to metal frames of different sizes.

[0014] 3. The waste material punched out by the punch will pass through the slot and fall into the slide. The waste material will slide along the slide into the material box, thereby collecting the punched waste material.

[0015] The above description is only an overview of the technical solution of the present invention.
