The invention relates to the field of machining of high-speed rail opening and closing mechanisms, in particular to a machining method of an opening and closing mechanism and a rail vehicle. The machining method of the opening and closing mechanism comprises the steps that the size of an aluminum alloy blank is designed according to the pre-designed size of the opening and closing mechanism; the aluminum alloy blank is placed on the top face of the lower die, the upper die, the lower die and the aluminum alloy blank are jointly heated to the preset temperature, and the upper die is driven by a lifting mechanism to do reciprocating motion so that part of the aluminum alloy blank can enter the concave part of the lower die; and when the aluminum alloy blank is pressed by the bottom surface, gas is introduced into the gap through the through hole of the upper die until the aluminum alloy blank is attached to the concave arc surface. According to the machining method of the opening and closing mechanism and the rail vehicle, the problems that an existing opening and closing mechanism is mainly made of glass fiber reinforced plastic, is large in weight and pollutes the environment, and an opening and closing mechanism which is deep in cavity, regular in curvature and uniform in wall thickness cannot be machined in an existing rapid aluminum alloy molding method are solved.

    本申请涉及高铁开闭机构的加工领域,尤其是涉及一种开闭机构的加工方法及有轨车辆。开闭机构的加工方法包括:根据预先设计的开闭机构的尺寸设计铝合金胚料的尺寸;将铝合金胚料放置在下模具的顶面,使上模具、下模具以及铝合金胚料共同升温至预定温度,通过升降机构带动上模具往复运动,以使铝合金胚料的部分进入下模具的凹陷内;当底面压紧铝合金胚料时,通过上模具的通孔向间隙中通入气体,直至铝合金胚料与凹陷弧面贴合。根据本申请的一种开闭机构的加工方法及有轨车辆,从而解决了现有的开闭机构主要由玻璃钢制成,重量大且污染环境,以及现有在对铝合金快速塑造成型的方法中,不能加工出深腔、曲率规则且壁厚均匀的开闭机构的问题。
