Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
1, the composition of a kind of titanium alloy rotation body cast paint frock of the present invention, include umbrella shape bar 1, starframe 2, in
Heart supporting plate 3, center-pole 4, reinforcing bar 5, side lever 6, bracing frame 7, fixed block 8 and (graphite) mould 9.Every tool construction and effect
(it is specifically illustrating and sees accompanying drawing 1～9) as follows:
(1) umbrella shape bar 1: as it is shown in figure 1, use normal carbon steel making, including flat board and cylinder, the end of cylinder is convex
The circular flat board risen, the other end of cylinder is threadeded with center-pole 4, drives module to rotate by pivotal plate, puts down simultaneously
Plate forms constraint in the horizontal direction, prevents module from coming off from bracing frame 7 in rotary course, and in shell dry run
It is easy to be suspended on drying frame.
(2) starframe 2: as in figure 2 it is shown, use normal carbon steel making, centrosymmetric stretch out four, the six roots of sensation or eight
Root bar, referred to as extension bar, on extension bar, the axis direction (along starframe 2 centre normal direction) along bar has elongate slots；Star
Frame 2 center drilling and center-pole 4 matched in clearance (center-pole 4 is through the centre bore of starframe 2), the elongate slots of extension bar and side lever
6 matched in clearance (one end of side lever passes elongate slots, and traversing through end is fixed by nut), by the nut pretension of side lever 6 to module
Horizontal direction form constraint, coordinate umbrella shape bar 1 to facilitate rotating module, unclamp the nut of side lever 6 end, side lever 6 can be along
The elongate slots of extension bar moves in centre normal direction, it is possible to realize the fixing rotation of different-diameter module.
(3) center supporting plate 3: as it is shown on figure 3, use normal carbon steel making, center drilling and center-pole 4 matched in clearance,
Center supporting plate is clipped in the middle of starframe 2 and module tundish, it is to avoid the destruction that side lever 6 pretightning force is excessive or spin friction is to module.
(4) center-pole 4: as shown in Figure 4, use normal carbon steel making, are positioned at module sprue center, center-pole 4 liang
End is threadeded with umbrella shape bar 1 (cylinder), near end protruding column boss, boss is made a call to four to eight holes and reinforces bar
5 matched in clearance, it is ensured that the rotatory force of umbrella shape bar 1 is delivered to reinforce bar 5 by center-pole 4 boss, and then drives the rotation of module.
In order to increase transmission efficiency, center-pole 4, near one section of upper little round platform of uniform welding of one end, increases the frictional force with sprue,
(top) other end and starframe 2 and center bracket 3 matched in clearance, can move, it is achieved differing heights module in the axial direction
Fixing rotation.
(5) bar 5 is reinforced: as it is shown in figure 5, use normal carbon steel making, be positioned at cross gate center, increase the strong of cross gate
Degree, it is to avoid the twisting resistance destruction to cross gate, reinforces and has elongate slots on bar 5, reinforces slotting position and size and star on bar
Frame keeps consistent, to realize the side lever movement along centre normal direction.Reinforce quantity and the starframe 2 extension bar quantity phase of bar 5
With.
(6) side lever 6: as shown in Figure 6, use normal carbon steel making, and two ends are respectively at starframe 2 and reinforce bar 5 gap
Coordinating, the two ends of side lever are each passed through starframe 2 and reinforce the elongate slots of bar 5, side lever with starframe 2, reinforce phase inside bar 5
Ortho position is put has nut, and traversing through end (i.e. adjacent position outside starframe 2, reinforcing bar 5) also has nut, by dual nut clip
Tightly, starframe 2, center bracket, center-pole 4 and reinforcing bar 5 are linked as entirety.Two ends have screw thread.
(7) bracing frame 7: as it is shown in fig. 7, use common straightcarbon steel round bar to be welded into two identical bracing frames 7, Mei Gezhi
Support 7 topmost two nuts of welding, for limiting the moving range of umbrella shape frame, prevent module from coming off bracing frame.Two supports
Frame 7 lays respectively at reinforcing bar 5, the both sides of starframe 2 of left and right, and lays respectively under the umbrella shape bar 1 of left and right.
(8) fixed block 8: as shown in Figure 8, use normal carbon steel making, rectangle, four sides fluting and bracing frame 7 nut
Matched in clearance, with bolt through fixed block (hole that left and right is corresponding) and the nut of bracing frame 7 that is positioned in fixed block, it is achieved with prop up
Support connects, and by the position of (fore-and-aft direction) regulation fixed block 8, module can be fixed on a certain position.The circle of umbrella shape bar 1
Post is between another nut and fixed block 8 of bracing frame 7.
(9) (graphite) mould 9: as it is shown in figure 9, according to the diameter of foundry goods and height, design disc type running channel model, use
Common graphite is processed into mould, the design of mould and fixing molding and the dismounting being easy to wax-pattern, side and lower openings, respectively with
Reinforcing bar 5 and center-pole 4 forms interference fits, wax liquid enters dies cavity from upper opening, forms disk running channel after solidification, in
Core bar and reinforcing bar are embedded in inside running channel.
Module is casting wax mould, umbrella shape bar 1, starframe 2, center supporting plate 3, side lever 6 and wax-pattern, center-pole 4, reinforces bar
The assembly of 5.
2, each frock is according to being combined assembling shown in Figure 10 to Figure 12, forms titanium alloy rotation body and casts shell work processed
Dress.
Frock has carried out combination assembling, and concrete assembling is as follows:
(1) take graphite jig 9 apart by order from top to bottom, mould 9 lower openings inserted in center-pole 4 lower end, it is ensured that
Center-pole vertical level, installs at center-pole 4 boss and reinforces bar 5, suitable center of rotation bar 4, it is ensured that reinforce bar 5 and mould
9 lateral openings coordinate.
(2) assembling graphite jig 9 according to order from down to up, group turns complete and pours wax at mould upstream cup
Liquid, it is ensured that center-pole 4 does not glances off, after wax liquid solidifies, opens mould in order, takes out wax-pattern, center-pole 4 and reinforces bar
The assembly of 5, this assembly, assembly welds formation module with casting wax mould.
(3) each side lever 6 two ends are respectively screwed into a nut, and side lever 6 one end (lower end) penetrates in reinforcing bar 5 groove, successively will
Center supporting plate 3, starframe 2 penetrate center-pole 4, and the direction adjusting starframe 2 makes the side lever other end (top) penetrate starframe
In elongate slots, being then screwed into a nut again at each side lever two ends, side lever moves to correct position along centre normal direction, uses
Nut screwing clamping, it is ensured that side lever is parallel with center-pole and degree of tightness suitable, finally installs umbrella shape bar 1 at the two ends of center-pole.
(4) according to the distance between umbrella shape bar 1, the distance between two bracing frames 7 is rationally set, and by (the most solid for fixed block 8
Determine groove) by being bolted on bracing frame 7 on bracing frame 7, finally module is put on bracing frame 7, and ensures that module exists
Smooth rotation between bracing frame.
Frock assembling combination completes, and just can carry out the shell processed of titanium alloy precision casting, in other approximation revolving structure casting
During the shell processed of part, as long as side lever 6 moves along centre normal, starframe 2 moves along center-pole 4, it is not necessary to again make frock,
Just the shell needs processed of different size foundry goods be can meet, practicality and the versatility of this frock embodied.
Frock fixes Ti alloy casting module, carries out paint case making, manual rotation's umbrella shape bar, module can frame at bracing frame
Upper stable rotation, it is ensured that being normally carried out of shell processed.
