The invention relates to the technical field of pouring-type dry-type transformer coil air passage arrangement, in particular to a pouring-type dry-type transformer coil air passage arrangement device which comprises a coil holder, an expansion component is mounted on the coil holder, and two outer rotary rings with the adjustable distance are connected to the expansion component. A rear baffle disc is rotatably mounted on the coil holder, a linear driving module is fixedly mounted on the coil holder, a front baffle disc which can be driven to rotate and move is in transmission connection with the linear driving module, a group of arrangement mechanisms which are arranged in a circumferential array manner is mounted between the rear baffle disc and the front baffle disc, and a driving module which is in transmission fit with the arrangement mechanisms is mounted on the coil holder. When the air passage arrangement device is used, on one hand, a formed coil can be rapidly and electrically discharged, rapid switching between the sealing state and the ventilation state of an air passage structure during coil pouring is achieved, and on the other hand, rapid mounting and dismounting of the air passage plate can be achieved when the air passage arrangement device is used.

The invention relates to a reverse rail hinge, comprising: a hinge outer part (12), a hinge inner part (13), a first pair of rails (22A, 23A) expanding towards an open side of the hinge outer part (12) when the reverse rail hinge is stretched, and a second pair of rails (22B, 23B) expanding towards a coupling side of the hinge outer part (12) when the reverse rail hinge is stretched; a respective ball (14A, 14B) in each first and second track pair; and a ball cage (15) having circumferentially distributed cage windows (18), each of which accommodates one of the balls (14). A second outer rail base line (G22B) of the joint outer part (12) runs radially inside a second outer reference arc (CRB12) starting from the joint center plane (EM) in the direction of the joint base (19) at the latest from a rail bend angle (beta ') of + / -20 DEG, the second outer reference arc is defined by a second outer radius (R22Bp) forming a second outer track baseline (G22B) in a second offset plane (EB).

The invention discloses a heat treatment process for improving the strength of an additive manufacturing nickel-based alloy FGH4098, and belongs to the technical field of metal additive manufacturing and heat treatment. Comprising the following steps: forming an FGH4098 alloy blank by adopting a selective laser melting (LPBF) technology; performing high-vacuum packaging treatment on the cleaned sample to construct a clean independent microenvironment; and then direct aging heat treatment at the temperature of about 760 DEG C is carried out. According to the method, a traditional high-temperature solid solution step is abandoned, and a micron-sized fine grain structure and a high-density dislocation network which are unique to a printing state are completely reserved; meanwhile, oxygen erosion in the heat treatment process is effectively isolated through vacuum packaging, oxidative depletion of key strengthening elements (Al and Ti) is prevented, and it is ensured that phases are fully dispersed and separated out in the pure environment. According to the invention, the problems of grain coarsening and softening caused by high-temperature solid solution and easy oxidative deformation in conventional aging in the prior art are solved, the tensile strength, hardness and dimensional stability of the alloy are remarkably improved, and short-process precision manufacturing of high-performance components is realized.
