Description

A laser cutting device for special-shaped hardware

Technical Field

The invention belongs to the technical field of cutting and processing special-shaped hardware, and in particular relates to a laser cutting device for special-shaped hardware.

Background Art

Special-shaped hardware refers to hardware accessories with non-standard or irregular shapes. They are usually used for specific installation or connection requirements and cannot be mass-produced through traditional standardized molds. This type of hardware may have complex curves, irregular angles or special geometric shapes, so customized processing technology is required to manufacture it. The laser cutting device for special-shaped hardware is a device designed specifically for processing such special-shaped hardware. It uses a high-energy laser beam to accurately cut hardware materials. This device usually includes a laser generator, a control system, a positioning system, and automated components, which can efficiently cut hardware according to preset graphics or CAD models. Among them, advanced devices may also be equipped with special-shaped hardware positioning and locking mechanisms to ensure accurate positioning and stable locking during the cutting process, so as to facilitate the processing of complex shapes that meet the requirements. The existing laser cutting devices for special-shaped hardware lack a collection and purification mechanism for the exhaust gas generated during cutting, which will bring about the disadvantage of environmental pollution.

For example, the invention with publication number CN117066737A discloses a laser cutting device for processing special-shaped hardware parts, wherein a base is arranged on the top of the leg, and the top of the leg is fixedly connected to the bottom of the base, support columns are evenly arranged on the top of the base, and the top of the base is fixedly connected to the bottom of the support column, a laser machine is arranged on the top of the support column, and the top of the support column is fixedly connected to the bottom of the laser machine, a fixing device is arranged inside the base, and the inner wall of the base is movably connected to the bottom of the fixing device, an auxiliary device is arranged on the top of the base, and the bottom of the auxiliary device is fixedly connected to the top of the base. In this patent scheme, it cannot effectively purify and discharge the exhaust gas generated during cutting. Smoke and harmful gases (such as nitrogen oxides, carbon monoxide, etc.) will be generated during the laser cutting process. Direct discharge without purification will seriously pollute the workshop air and affect the health of workers. Some gases may be flammable and explosive. Improper handling will increase the risk of fire or explosion. Long-term exposure to exhaust gas containing corrosive components may damage the optical elements and other precision components of the laser cutting equipment, which does not meet the requirements of environmental protection regulations. Enterprises may face fines or be forced to suspend operations for rectification.
