Description

Technical Field

[0001] The utility model relates to the technical field of parts spraying, in particular to a hole-opening device for civil air defense door accessories. Background Art

[0002] Civil air defense door accessories refer to various accessories and devices installed on civil air defense doors to enhance the function, safety and aesthetics of the doors. They are usually equipped with high-security lock systems, such as multi-point locks, fingerprint recognition locks, password locks, etc., to ensure the safety of the doors. In order to increase the impact resistance of the doors, civil air defense doors are usually equipped with anti-collision strips, which can reduce the degree of damage to the doors when they are impacted by external forces. In order to improve the light transmittance of the doors, some civil air defense doors may be equipped with transparent glass so that people can see each other indoors and outdoors, increasing the sense of security. In the production of civil air defense doors, there will be many accessories that need to be made, so it is necessary to use civil air defense door accessories to use opening equipment to punch holes in the accessories.

[0003] Traditional drilling equipment for civil air defense door accessories needs to ensure that the surface of the civil air defense door is clean and mark the locations where holes need to be drilled before drilling. At the same time, prepare a suitable drill bit or drilling mold. The drill bit is installed on the main shaft, and the drill bit is driven to rotate by an electric motor to drill holes in the accessories. After drilling is completed, clean up the chips and waste on the surface of the door body in time, and inspect the punched area to ensure the quality of drilling and the integrity of the door body.

[0004] However, the process of replacing the drill bit of traditional hole-punching equipment for civil air defense door accessories is cumbersome or time-consuming, which will affect production efficiency. On a production line where drill bits need to be replaced frequently, operators need to spend a lot of time replacing drill bits, thereby increasing production cycle and cost. Therefore, a hole-punching equipment for civil air defense door accessories is proposed to solve the above problems. Utility Model Content
