Technical field
The utility model relates to casting technology field, particularly relates to a kind of endless belt sand core rod bridge-type and connects anti-deforming structure.
Background technology
Heavy combustion engine exhaust casing foundry goods is the important composition parts in gas-turbine unit, and need bear HTHP, work under bad environment at the medium and heavy combustion engine exhaust casing of engine operation process, therefore the quality of cylinder body directly affects the safety of equipment.So strict especially to the quality requirement of cylinder body in the fabrication process, exhaust casing body structure is comparatively complicated, needs to be cooperatively interacted by multiple core in modeling process, and will ensure that each core dimensional accuracy and intensity meet the requirements, guarantee casting quality.
As shown in Figure 1, need use endless belt core 2 when heavy combustion engine exhaust casing foundry goods 1 is shaping, its diameter dimension is large, and thickness is thin, and core cross section is less; Its maximum gauge is Ф 2140mm, and arc length reaches 3000mm, core height 323mm, and thickness is only 102mm, and the core of this annular thin wall structure very easily damages; Therefore in molding, handling and lower core process, all need the balance and stability keeping core, otherwise be easy to make endless belt core produce distortion, ftracture and cause core to damage.Above technical process as adopted conventional method and structure, due to the vertical rod circular array of drawing in endless belt core, therefore molding, handling and lower core time balance be difficult to grasp.
Summary of the invention
The utility model provides a kind of endless belt sand core rod bridge-type and connects anti-deforming structure, by the vertical rod of circular array of drawing in the endless belt core space transforming by structure, form the balancing stand of horizontal square, core is made more easily to keep balanced steady state in molding, handling and lower core process, and lower core Adjustment precision and efficiency all can improve, method is simple, processing ease.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of endless belt sand core rod bridge-type connects anti-deforming structure, and comprise endless belt core, arbor, vertical rod and connecting rod, described arbor is the skeleton construction being located at endless belt sand core internal, and the balancing stand consisted of 4 vertical posts and 4 connecting rods is fixedly connected with; Vertical rod is arranged along endless belt core even circumferential, and the balancing stand of connecting rod composition is square structure.
Be welded to connect between described arbor and vertical rod, vertical rod top establish the hook ring that bends and connecting rod fixing after be welded to connect.
Compared with prior art, the beneficial effects of the utility model are:
1) by the vertical rod of circular array of drawing in endless belt core by the space transforming of structure, forms the balancing stand of horizontal square, make core more easily keep balanced steady state in molding, handling and lower core process, and method is simple, processing ease;
2) upper core box adopts split-type structural, in the boundary of reserved pole perforating hole position, makes total can be shaping before molding, core will be caused to damage because of assembly welding;
3) vertical rod and all adopting between arbor and connecting rod is welded to connect, solid and reliable, can not occur to loosen sliding phenomenon in course of action;
4) under, during core, the adjustment of endless belt core position is more accurate, is conducive to improving foundry goods Forming Quality, improves work efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 2-Fig. 3, is structural representation of the present utility model.A kind of endless belt sand core rod of the utility model bridge-type connects anti-deforming structure, comprise endless belt core 2, arbor, vertical rod 3 and connecting rod 4, described arbor is the skeleton construction being located at endless belt core 2 inside, and the balancing stand consisted of 4 vertical posts 3 and 4 connecting rods 4 is fixedly connected with; Vertical rod 3 is arranged along endless belt core 2 even circumferential, and the balancing stand that connecting rod 4 forms is square structure.
Be welded to connect between described arbor and vertical rod 3, vertical rod 3 top establish the hook ring that bends and connecting rod 4 fixing after be welded to connect.
The principle that a kind of endless belt of the utility model sand core rod bridge-type connects anti-deforming structure is as follows with making using method:
When making endless belt core core box, reserve 4 pole perforating holes 6 evenly arranged along upper core box 5 circumference, upper core box 5 adopts Split type structure, punishes boundary at pole perforating hole 6; (as shown in Figure 4)
During welding arbor, weld 4 vertical posts 3 in the position that the upper strata arbor welded is corresponding with pole perforating hole 6, vertical rod 3 height be exposed at after core box matched moulds outside core box 5 is 500 ~ 600mm;
The normal moulding of core, places 2 pieces of equal height cushion blocks, equal height cushion block places 4 connecting rods 4 after sand mold sclerosis on upper core box 5, and adjustment connecting rod 4 position makes it form square structure with vertical rod 3 roof intersection respectively;
Connecting rod 4 is welded into balancing stand, then itself and vertical rod 3 is integrally welded, withdraws from cushion block, take off core box 4, to hang on balancing stand 2 parallel rods apart from each other 4 with crown block hook, molding;
After lower core completes, the vertical rod 3 being exposed at endless belt core 2 outside removed, having repaired core 2 can carry out subsequent processing.
Pole perforating hole 6 can be circular or square, and its diameter or the length of side are greater than vertical rod 3 diameter 10 ~ 20mm.
Following examples are implemented under premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment]
As shown in Figure 2 and Figure 4, in the present embodiment, endless belt core is reserved with 4 uniform through holes directly over core box 5 as pole perforating hole 6, size 30mm × 30mm; Arbor adopts Ф 16 round steel to be welded into skeleton (do not show in figure, this is conventional structure); Passing four Ф 16 round steel as vertical rod 3 by 4 pole perforating holes 6 above core box, is highly 600mm.
Make the wooden cushion block that two are highly 550mm, when ensureing that connecting rod 4 is welded into balancing stand, level height is consistent; Cushion block is placed on upper core box 5,4 Ф 50 steel pipes are placed on cushion block as connecting rod 4, adjustment connecting rod 4 position and angle make it form square respectively with vertical rod 3 roof intersection, vertical rod 3 top bends hook ring and connecting rod 4 is fixed, connecting rod 4 is welded into the balancing stand of square, then balancing stand and vertical rod 3 is welded and fixed;
Withdraw from cushion block, core box 5 is taken off in segmentation, and hang on the parallel connecting rod 4 of apart from each other 2 of balancing stand with crown block hook, molding, handling, lower core, in the process, endless belt core 2 remains balanced steady state, without any damage; Adjust accuracy during lower core high, technical process is efficient smoothly.After lower core completes, the vertical rod 3 being exposed at endless belt core 2 outside is removed, after being repaired by the core 2 removing upright part, enter subsequent processing.
