An appliance immersion tank system comprising: a generally rectangular tank adapted to immerse in a dielectric fluid a plurality of appliances, each in a respective appliance slot distributed vertically along, and extending transverse to, the long axis of the tank; a primary circulation facility adapted to circulate the dielectric fluid through the tank; a secondary fluid circulation facility adapted to extract heat from the dielectric fluid circulating in the primary circulation facility, and to dissipate to the environment the heat so extracted; and a control facility adapted to coordinate the operation of the primary and secondary fluid circulation facilities as a function of the temperature of the dielectric fluid in the tank. A plenum, positioned adjacent the bottom of the tank, is adapted to dispense the dielectric fluid substantially uniformly upwardly through each appliance slot. A weir, integrated horizontally into a long wall of the tank, is adapted to facilitate substantially uniform recovery of the dielectric fluid flowing through each appliance slot. All active and most passive components of both the primary and secondary fluid circulation facilities, and the control facility are fully redundant, and are adapted automatically to operate in a fail-soft mode.

The utility model discloses a die structure giving consideration to development, mass production and die holder universality, which comprises a split female die, a split male die, a blank holder, an upper die holder and a lower die holder, a plurality of U-shaped mounting grooves are uniformly distributed at the bottom of the split female die and the split male die in the circumferential direction, and a first guide structure is arranged on the inner ring surface of the blank holder. A second guiding structure in sliding fit with the first guiding structure is arranged on the peripheral face of the split male die, a guiding inserting plate is detachably installed on the peripheral face of the split female die, a guiding inserting groove in sliding fit with the guiding inserting plate is formed in the periphery of the blank holder, the upper die base and the lower die base are of a plate type structure, and an upper die base guiding base is matched with a lower die base guiding leg for guiding. According to the die structure, fixing, guiding and supporting structures which are both used in the soft die development stage and the normal die mass production stage are designed at the same time, the split concave-convex die and the blank holder which are successfully developed can be continuously used after heat treatment is completed, the upper die base and the lower die base are subjected to universal design and can be matched with different dies to be repeatedly used, and therefore the die development period is shortened, and the production efficiency is improved. The development cost is reduced.

The application provides a device for metal pipe forming. The device for metal pipe forming comprises a upsetting-extruding die and a soft die bulging die. The upsetting-extruding die comprises an upper upsetting-extruding insert assembly and a lower upsetting-extruding insert assembly, a first accommodating space for accommodating a metal pipe to be processed is formed between the upper upsetting-extruding insert assembly and the lower upsetting-extruding insert assembly, and a preforming structure is arranged on each of the upper upsetting-extruding insert assembly and the lower upsetting-extruding insert assembly. The soft die bulging die comprises an upper soft die insert assembly and a lower soft die insert assembly, a second accommodating space for accommodating the metal pipe to be processed is formed between the upper soft die insert assembly and the lower soft die insert assembly, and the upper soft die insert assembly is provided with a soft die structure. The problem that the wall thickness is seriously thinned and the uniformity is poor due to small round angle and large deformation in the bulging area of the metal pipe in the prior art is solved.

The present application belongs to the technical field of plate forming, and relates to a plate high-strain-rate-controllable-soft-mold coupling precision forming device and method. The device comprises an electromagnetic pulse generating unit, a driving plate, a plunger, a pressure ring, a medium bin, a magnetic field auxiliary device, a coil and a female die. The female die is arranged at the lower end of the medium bin, and the plate is placed between the medium bin and the female die. The cavity between the medium bin and the plate is filled with magnetorheological fluid. The plunger is placed at the upper end of the cavity of the medium bin, the driving plate is placed on the upper end surface of the plunger, and the electromagnetic pulse generating unit is located on the upper end of the driving plate. In the initial stage of forming, the magnetic field auxiliary device is arranged at the periphery of the bottom of the plunger. In the later stage of forming, the magnetic field auxiliary device is arranged at the center of the bottom of the plunger. The device can realize the precision forming of the plate under the coupling action of high strain rate and controllable soft mold, improve the plasticity of the material under high strain rate from the inside of the material, provide suitable soft mold stress state for different deformation regions of the plate from the outside, regulate the deformation, and realize the precision forming of the part.
