Manufacturing method of civil defense door closing structure
The invention discloses a civil defense door closing structure. the civil defense door closing structure is manufactured through the steps of performing high-temperature treatment on steel, and then directly upsetting the treated steel to obtain blanks with the approximate shape and size through a cold header; performing deep processing on shaft cover blanks by using a numerical control lathe or asmall lathe, and respectively processing a first end cover, a baffle, a rack, a shell, a second end cover and a gear; placing the first end cover and the second end cover which are qualified in sizeon a thread rolling machine to be processed into threads; welding and fixing baffles to the two ends of the rack, and welding and fixing one end of a spring is to the baffle on one side of the rack; enabling one end deviating from the baffle, of the spring to be clamped and mounted in a clamping groove of the second end cover; mounting the first end cover at one end of the shell, and mounting thesecond end cover connected with the spring and the rack at the other end of the shell; inserting and mounting the gear below the rack in the shell in a rotary sealing manner; and pouring hydraulic oilinto the shell, and mounting a sealing plug. The civil defense door closing structure has the advantages that internal components are preferentially assembled into a whole, so that the civil defensedoor closing structure is modularized, and the assembling efficiency of the door closing structure closer is improved.
发明公开了一种人防门闭门结构，将钢材经过高温处理后直接用冷镦机镦成大致形状和尺寸的坯料；用数控车床或小型车床对轴盖坯料进行深加工，分别加工出第一端盖、挡板、齿条、外壳、第二端盖和齿轮；将合格尺寸的第一端盖和第二端盖放在滚丝机上加工出螺纹；将挡板焊接固定在齿条的两端，并将弹簧的一端与齿条一侧的挡板焊接固定；将弹簧背离挡板的一端卡接安装在第二端盖的卡接槽内；将第一端盖安装在外壳的一端，并将连接有弹簧和齿条的第二端盖安装在外壳的另一端；将齿轮通过转动密封插接安装在外壳内齿条的下方；向外壳内灌注液压油，并安装密封塞。发明具备优先将内部组件组装为一个整体，使其模块化，进而增加闭门器组装效率的优点。
