4results about How to "High separation reliability" patented technology

This invention belongs to the field of aircraft separation structure design technology, specifically relating to an explosive bolt collection device and its design method suitable for compact axial space. The method includes: Step 1, determining the initial velocity and initial kinetic energy of the explosive bolt remnant; Step 2, selecting buffer structure connecting fasteners based on the initial kinetic energy of the explosive bolt remnant calculated in Step 1; Step 3, designing the collection structure based on the initial kinetic energy of the explosive bolt remnant calculated in Step 1 and the buffer structure connecting fasteners selected in Step 2; Step 4, conducting numerical simulation analysis and ground tests on the bolt collection device designed in Steps 2 and 3 to verify the feasibility of the design method for an explosive bolt collection device suitable for compact axial space. This invention can solve the problems of complex structure, high axial space requirements, and the risk of rebound in explosive bolt collection devices.

A large-diameter tension-compression decoupling fusion type linear separation device is composed of a separation ring, an inner support protective cover, a detonator seat, an energy-gathering cutting cable assembly, a connecting fastener and a detonator, the protective cover is internally provided with the energy-gathering cutting cable, after the detonation energy is transmitted to the main charge of the cutting cable through the transmission assembly of the detonator, the shaped charge is driven by the detonation wave to form a metal jet to cut and separate the separation ring, the high-level load transmitted by the projectile body is tension-compression decoupled through the tolerance control of the separation ring and the inner support protective cover, and a large-diameter tension-compression decoupling fusion type linear separation device is given, which has the advantages of simple structure, reliable separation performance, high bearing capacity, large connection stiffness, light weight, convenient installation and the like.

The utility model relates to the technical field of labeling and coding all-in-one machines, and discloses a labeling and coding all-in-one machine convenient to adjust, which comprises a winding bracket and a transmission belt, the key point is that stable separation of a label layer and a backing paper layer is realized through a cooperative structure of a turning roller and a rough roller; a backing paper layer of a label roll is wound on the turning roller in a U shape, the thick roller is driven by a servo motor, and the outer wall of the thick roller adsorbs the label layer through negative pressure, so that the label layer is separated from the backing paper layer and turns to one side of the transmission belt. Two pressing rollers on the other side of the transmission belt are connected with a double-rod air cylinder through a movable frame, the round bottles can be extruded to the outer wall of a rough roller, and label layers are precisely attached to the peripheries of the round bottles through glue; the label height adjusting platform arranged below the material rolling support comprises a fixing plate, a lifting plate and a rhombic lifting frame, a distance adjusting screw rod is driven by a double-head motor to achieve electric adjustment of the height of the material rolling support, and the label height adjusting platform can be rapidly matched with round bottles of different heights.
