Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting, specifically to a sheet metal cutting device that facilitates blanking. Background Technology

[0002] A die-cutting sheet metal cutting device is a specialized piece of equipment used to process sheet metal. It cuts sheet metal into specific shapes using a die and pressure. This device typically consists of a die, a press, a positioning system, and a control system, enabling efficient and precise cutting of complex shapes. Its working principle involves placing the sheet metal material on the die, and applying pressure through the press, causing the die's cutting edge to cut the material. Die-cutting sheet metal cutting devices are widely used in industries such as automotive, home appliances, and construction, offering advantages such as high precision, high efficiency, and mass production capabilities.

[0003] Chinese patent CN212216806U discloses a thermoforming synchronous trimming mold, including an upper mold base, an upper mold insert located within the upper mold base, a lower mold base, and a lower mold insert located within the lower mold base. A nitrogen cylinder is installed within the upper mold base. The upper mold insert is connected to the nitrogen cylinder via an upper mold pressing core. The upper mold insert has a piercing blade with a V-shaped structure. The lower mold insert corresponds to the upper mold insert in position. This device, through the coordinated action of the upper mold base, upper mold insert, lower mold base, and lower mold insert, enables thermoforming of sheet metal parts. The piercing blade on the upper mold insert allows for direct trimming during the thermoforming process, significantly reducing the cost of subsequent laser cutting. Furthermore, the device has a simple structure and can directly transmit the pressure from the press to the piercing blade, achieving both forming and trimming effects. However, this device still has the following problems:

[0004] 1. After die-cutting, the sheet metal parts remain in the lower mold, and they need to be manually removed from the lower mold, which is inconvenient.

[0005] 2. The material needs to be manually aligned during loading, which is time-consuming and delays production.
