The invention provides a hot working pressing and releasing device. The hot working pressing and releasing device comprises a pressing assembly and a pluggable device assembly. The pressing assembly comprises a first pressing rod and a second pressing rod, the first pressing rod is fixedly arranged, and the second pressing rod is arranged in a sliding mode in the length direction of the pressing assembly so as to press and unlock all the effective loads. The pluggable device assembly comprises a pluggable pin, and the pluggable pin is provided with a pair of first inclined faces. The first pressing rod and the second pressing rod are correspondingly provided with clamping grooves, and the clamping grooves are provided with a pair of second slopes matched with the first slopes. When the pressing assembly is in a pressing state, the first pressing rod and the second pressing rod are connected, the inserting and pulling pin is inserted into the clamping groove, and the first inclined face abuts against the second inclined face. During pressing, the pre-tightening force of the pressing and releasing device is transmitted to the connecting inclined plane of the inserting and pulling pin and the pressing rod, component force in the moving direction of the inserting and pulling pin can be generated according to the stress condition, the pulling-out force needed by the inserting and pulling pin is greatly reduced, and therefore the internal explosive loading amount of the hot working inserting and pulling device is reduced, and the impact load generated when the hot working inserting and pulling device is detonated is reduced.

    本发明提供一种火工压紧释放装置,包括压紧组件和插拔器组件。压紧组件包括第一压紧杆和第二压紧杆,第一压紧杆固定设置,第二压紧杆沿压紧组件长度方向滑动设置,以将各有效载荷压紧和解锁。插拔器组件包括插拔销,插拔销设有一对第一斜面。第一压紧杆和第二压紧杆对应设有卡槽,卡槽设有与第一斜面相配合的一对第二斜面。当压紧组件处于压紧状态,第一压紧杆和第二压紧杆相连接,插拔销插入卡槽中,第一斜面与第二斜面相抵。压紧时压紧释放装置的预紧力传递至插拔销与压紧杆的连接斜面上,根据受力情况,会产生沿插拔销移动方向的分力,极大地减小了插拔销所需的拔出力,从而减少火工插拔器的内部装药量,降低火工插拔器起爆时产生的冲击载荷。
