Description
Technical field
The utility model relates to a kind of device that prevents large-diameter magnesium alloy shell-pieces heat treatment deformation, belongs to magnesium alloy shell part heat treatment technics field.
Background technology
At present; The cast magnesium alloys shell-pieces is the key part of spacecraft, and along with the development of spacecraft technology, it is big that the cast magnesium alloys diameter of the housing becomes; Thermal treatment has proposed new technical requirements to housing; Especially the deformed Control Technology of major diameter shell casting in heat treatment process directly has influence on cast magnesium alloys housing qualification rate, and the factor that influences major diameter cast magnesium alloys housing distortion generally has: solid solution and timeliness thermal treatment temp, foundry goods are gone into the heat treatment clamping mode of stove mode, part etc.According to conventional magnesiumalloy heat treatment technics standard; To thermal treatment temp, go into the stove mode and be optimized combination; And shell-pieces carried out general clamping, shell-pieces diameter less (being generally less than 300mm), the heat treatment deformation amount can be controlled in the machining allowance scope of reservation; But; When the diameter of magnesium alloy shell when big (greater than 300mm), according to existing heat-treatment technology method, and when taking traditional mode to carry out clamping; Moderate finite deformation will take place in the housing of its large-diameter magnesium alloy shell-pieces; The deflection that its thermal treatment produced tends to exceed the machining allowance scope of reservation, can't satisfy technical requirements, thereby causes scrapping of part.So the heat treatment process mode of existing large-diameter magnesium alloy shell-pieces still is not ideal enough.
Summary of the invention
The purpose of the utility model is: a kind of simple in structure, easy to operate and deflection is less, qualification rate is higher when heat treatment process device that prevents large-diameter magnesium alloy shell-pieces heat treatment deformation is provided, to overcome the deficiency of prior art.
The technical scheme of the utility model is to constitute like this: a kind of device of large-diameter magnesium alloy shell-pieces heat treatment deformation that prevents of the utility model is: this device comprises pallet; On pallet, be fixed with lower disc; On lower disc, be provided with union lever; On union lever, be with the adjusting sleeve pipe, can will regulate sleeve pipe and be fixed on the locking bolt on the union lever regulating to be equipped with on the sleeve pipe, on the adjusting sleeve pipe, disk is installed; The center of circle of lower disc and last disk is all on same axis heart line, and the outside diameter of lower disc 2 and last disk 3 is all less than the barrel bore of the large-diameter magnesium alloy shell-pieces 7 of processed drum.
The outside diameter of above-mentioned lower disc and last disk is less than 1～6 millimeter of the diameter of bore of the large-diameter magnesium alloy shell-pieces of processed drum.
The outside diameter of above-mentioned pallet is more than or equal to the outside diameter of processed large-diameter magnesium alloy shell-pieces.
The outside diameter of above-mentioned large-diameter magnesium alloy shell-pieces is more than or equal to 300 millimeters.
The thickness of above-mentioned lower disc and last disk is 20 millimeters～50 millimeters.
Last disk is installed to be connected through the mode that is threaded and is regulated on the sleeve pipe.
On last disk, be provided with 1～6 removal hole.
Upper end at union lever is connected with suspension rod, and the hook on the suspension rod is arranged on the top of disk.
Owing to adopted technique scheme; The utility model is at first according to the internal diameter size of large-diameter magnesium alloy shell-pieces to be heated and height; Select corresponding lower disc and last disk and assemble; Be respectively equipped with lower disc and last disk near making the inwall of two ports of large-diameter magnesium alloy shell-pieces; The large-diameter magnesium alloy shell-pieces is being hung in when carrying out solid solution and timeliness thermal treatment in the HTFX like this; Because the existence of lower disc and last disk, the side-play amount of the former central axis of mutual skew when two ports of restriction large-diameter magnesium alloy shell-pieces are deformed remains within the tolerance zone of permission the distortion of two ports of large-diameter magnesium alloy shell-pieces.So the utility model can prevent or reduce the distortion that the large-diameter magnesium alloy shell-pieces is produced effectively through this method that lower disc and last disk are set respectively when thermal treatment in two ports of large-diameter magnesium alloy shell-pieces.Through the actual proof of using, adopt the product percent of pass of the large-diameter magnesium alloy shell-pieces of the utility model processing to reach more than 98%.So; The utility model compared with prior art; The utility model not only has simple in structure, easy to operate advantage, but also has deflection, the advantages such as processing quality is good, product percent of pass is high, good operating stability that when heat treatment process, can effectively control part to be processed.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The enforcement of the utility model: the utility model is to make up according to following a kind of method of large-diameter magnesium alloy shell-pieces heat treatment deformation that prevents; This method is implemented when adopting existing solid solution and timeliness thermal treatment process to handle the large-diameter magnesium alloy shell-pieces; Promptly this method is before processed large-diameter magnesium alloy shell-pieces 7 being put into existing HTFX and being carried out solid solution and timeliness thermal treatment by traditional heat treatment mode; Make a pallet 1 earlier; And on pallet 1 fixing lower disc 2; Disk 3 on connecting one through union lever above the lower disc 2; Entangle the large-diameter magnesium alloy shell-pieces 7 of drum and be placed on vertically on the pallet 1 with lower disc 2 and last disk 3 then, make disk 3 be in the position of the port of large-diameter magnesium alloy shell-pieces 7, and make between the cylinder inner wall of external cylindrical surface and large-diameter magnesium alloy shell-pieces 7 of lower disc 2 and last disk 3 and be reserved with 0.5～4 mm clearance; Then large-diameter magnesium alloy shell-pieces 7 is hung in the HTFX and by traditional solid solution and timeliness heat treatment mode together with pallet 1 vertically and heat-treat; Through this method that lower disc 2 and last disk 3 are set respectively, can prevent or reduce the distortion that the large-diameter magnesium alloy shell-pieces is produced when thermal treatment in two ports of large-diameter magnesium alloy shell-pieces 7; When in the stove that large-diameter magnesium alloy shell-pieces 7 is hung in vertically HTFX together with pallet 1, carrying out solid solution and timeliness thermal treatment; For the part that prevents magnesium alloy materials at high temperature burns; Can in the stove of HTFX, place some sulfurous iron ore simultaneously; Its sulfurous iron ore can adopt the sulfurous iron ore of existing any taste, and the consumption of sulfurous iron ore generally should not be lower than 20 kilograms, but is not higher than 500 kilograms (consumption of sulfurous iron ore is too many can to increase energy consumption); Can when being heated, will absorb the oxygen in the stove through sulfurous iron ore like this, prevent 7 burnings of large-diameter magnesium alloy shell-pieces thereby form a kind of protective atmosphere.
