Background technology
Large aluminum alloy heat treating castings frock can substantially be divided into two classes at present：One kind enables aluminum alloy to casting and is directly placed into
Solid solution inframe carries out solution treatment, it is only necessary to which material frame position is bright and clean smooth corresponding to casting lower surface, but the method
Can not deformation that effectively placing aluminium alloy casting occurs in heat treatment process, be not suitable as the heat of large aluminum alloy casting
Processing Equipment.Another kind of is the heat treatment deformation frock prepared with the mode of integral solder, as shown in figure 1, aluminium alloy
The lower surface of casting is placed on end face slab 1, and casting lower surface seam prevents casting to be heated by the support of anti-deformation arc plate 2
When inside contraction distortion, inside contraction distortion when casting upper surface seam prevents casting heated by the support of anti-deformation arc plate 3；
Because aluminium alloy castings inner-cavity structure is complicated, casting is put into relatively difficult in frock, casting turns sequence taking-up after the completion of heat treatment
When be also not easy to take out；Anti-deformation arc plate 2, anti-deformation arc plate 3 and end face slab 1 are by welding and frock framework
Connection, causes anti-deformation arc plate 2 and anti-deformation arc plate 3 and casting in welding process because the pulling force of support frame 4 is inconsistent
Upper and lower end face seam gap is inconsistent, for the effect and bad for preventing large aluminum alloy heat treating castings from deforming, casting in addition
It is difficult to be heat-treated the DATA REASONING of aft gap, so as to be unable to contraction situation of the accurate judgement casting in heat treatment process；Separately
Outer such heat treatment tooling can only be heat-treated for a kind of casting model, and when changing casting model, the heat treatment tooling is not
Can reuse, also need to remake, waste time and energy, cost it is higher.

Brief description of the drawings
Fig. 1 is the structural representation of tubular heat treating castings frock of the prior art；
Fig. 2 is the structural representation of the specific embodiment of tubular heat treating castings frock of the present invention.
Embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the tubular heat treating castings frock of the present invention, as shown in Fig. 2 tubular heat treating castings frock bag
Support frame 8 is included, the upper/lower terminal of support frame 8 is connected to upper surface flat board 9 and lower surface flat board 5；The He of upper surface flat board 9
Lower surface flat board 5 is spliced by materials in the tube section bar and sector flat plate, and then milling is flat is fabricated to monoblock type, to be used as general bottom
Plate, strengthen the interchangeability between fixture component, materials in the tube section bar is square, and squared profile has been spliced to form circular frame, circular frame
Frame, which is provided with, is used for the bolt hole that be connected with support frame 8, and sector flat plate splicing is on circular frame, and sector flat plate is radially and axle
Multigroup pin-and-hole is equipped with to direction, wherein, the form of splicing is welding；It is logical on each sector flat plate of lower surface flat board 5
Cross fastener and be fixed with lower arc plate 6, upper arc plate 6 constitutes keeper, on each sector flat plate of upper surface flat board 9
Upper arc plate 10 is fixed with by fastener, upper surface flat board 9 constitutes lower keeper, wherein, fastener is alignment pin 7, fixed
Position pin 7 both plays positioning action, also plays the fixation to arc plate simultaneously.
In the present embodiment, upper arc plate 10 and lower arc plate 6 are respectively according to the upper and lower end face seam shape of aluminium alloy castings
To change size, and positioned in radial directions by alignment pin 7, with the upper of the aluminium alloy castings to different-diameter
End face seam and lower surface seam are positioned.The maximum gauge of casting lower surface should be less than or straight equal to lower surface flat board 5
Footpath, the maximum gauge of casting upper surface should be less than or the diameter equal to upper surface flat board 9.
In the present embodiment, upper surface flat board 9 and lower surface flat board 5 and the releasable connection of support frame 8, upper surface flat board 9 is with
End face slab 5 is connected with support frame 8 by bolt 11, is connected by bolt 11, is easy to dismount, and when support frame is highly improper
When need to only change support frame；When needing to heat treating castings upper surface flat board 9, lower surface flat board 5 and support frame 8
Disassemble out, casting is attached on lower surface flat board 5, then support frame 8 is threaded on lower surface flat board 5 again, finally handle
Upper surface flat board 9 is threaded on support frame 8, to complete installation of the casting on heat treatment tooling；The main body of support frame 8 is
Eight square tube sections, square tube upper and lower end face are welded with square plate thick 30mm, after the completion of upper and lower side facing cut put down, drill, attack
Silk.
In the present embodiment, upper surface flat board 9, lower surface flat board 5, the material of upper arc plate 10 and lower arc plate 6 are heat
Make mould steel, the frock is used as from H13 hot die steels and prepares material.
When it is implemented, this heat treatment tooling uses T6 processing, produce meet aluminium alloy castings upper and lower end face seam and
The upper arc plate 10 and lower arc plate 6 of anti-deformation process requirement, and determine that the needs of arc plate 10 are consolidated on upper surface flat board 9
Fixed position is simultaneously fixed by alignment pin 7, the fixed position of the needs of arc plate 6 and by fixed under being determined on lower arc plate 5
Position pin 7 is fixed；First casting is placed on lower surface flat board 5 before heat treating castings, regulated between lower arc plate 6 and casting
Gap, and record, then support frame 8 is installed, finally install end face slab 9, need first to measure after the completion of heat treating castings
The change of casting and frock gap width, frock is then broken in order, take out casting.
Carry out the large aluminum alloy casting of T6 processing using monoblock type heat treatment tooling, each shove charge and come out of the stove and all need 4
People could be placed and taken out aluminium alloy castings time-consuming 2 hours.Put every time, due to frock and aluminium alloy castings it is reserved between
Gap value is uneven, and deformation rate is 20% after the completion of causing aluminium alloy castings heat treatment, and when casting model is changed, must be weighed again
New production heat treatment tooling, the average unit cost of serious increased casting.Equipped using Technology for Heating Processing of the present invention and carry out T6 processing
Aluminium alloy castings, each shove charge and coming out of the stove only needs people to complete for time-consuming 2 hours, by regulation can ensure frock with
In controlled range, the heat treatment deformation rate for enabling aluminum alloy to casting is reduced to 5% by 20% in gap between casting.Changing casting
When model is carried out, as long as the end face maximum gauge of new casting, in the diameter range of end face slab, end face slab can repeat
Use, not only save the material and cost of labor for remaking frock, also improve production efficiency.
In other embodiments, support frame can only with lower surface flat board is removable connects, be fixedly connected with upper surface flat board；
Support frame can also be fixedly connected, two methods facilitate casting only with upper surface flat board releasable connection with lower surface flat board
Installation.
In other embodiments, upper surface flat board 9, lower surface flat board 5, upper arc plate 10 and lower arc plate 6 can also be by
Other hot-work die steel materials are made, such as 3Cr2W8V.
