Abstract
The utility model discloses a loose piece die of a large belt wheel casting groove combined mould, which comprises a flexible matrix. The matrix is in ring shape which is provided with an opening, a closing mechanism is arranged at the opening of the matrix, and the shape of the cross section of the matrix is adaptive to that of the section of wheel groove wall of a belt wheel. For the loose piece die, the matrix adopts the ring shape, and the deformation at the opening is smaller, so that the casting precision is improved; wedge-shaped and magnetic force connection is adopted at the opening, so that the sealing at the opening is improved, and further the deformation at the opening is reduced, and the casting precision is improved; and the loose piece die is convenient for use, simple in operation, and high in working efficiency. As the loose piece matrix has high flexibility and cutting performance, the loose piece matrix is suitable for casting belt wheels, and has obvious economical efficiency. The loose piece die is suitable for the use for the large belt wheel casting groove combined mould with diameter of more than 400 mm.
Description
Technical field
The utility model belongs to field of metal casting technology, particularly relates to a kind of loose piece pattern of large-scale belt pulley casting groove built-up pattern.
Background technology
Grooved is not cast in the general employing of furan resin self curing sand casting large-scale belt pulley.Because wheel rim and spoke joint thermal center are thicker, be worked into the bottom land place and occur shrinkage porosite cavity class defective easily, serious meeting directly causes scraps.Do not cause machine-finish allowance big owing to do not cast groove simultaneously, generally compare the high 15-25% of material consumption than casting groove belt pulley, processing capacity greatly also can bring the prolongation of machining period.
At present, furan resin self curing sand casting large-scale belt pulley adopts flat type flute profile rubber loose piece often because the interior external diameter of loose piece is poor when realizing casting groove technology, causes the variation of rubber loose piece interface grooved, influence casting grooved precision.Interface adopts adhesive tape to connect and is not easy to loose piece assembling and loose piece extraction simultaneously, and operating efficiency is low.
The utility model content
The utility model can satisfy casting groove precision for the technical problem that exists in the solution known technology provides a kind of, and the large-scale belt pulley of being convenient to assemble and extract out is cast the loose piece pattern of groove built-up pattern.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of loose piece pattern of large-scale belt pulley casting groove built-up pattern, comprise flexible substrate, described matrix is the annular that is provided with opening, the opening part of described matrix is provided with close mechanism, and the shape of cross section of the shape of cross section of described matrix and belt pulley wheel cell wall is adaptive.
Described close mechanism comprises conformal magnetic core that is positioned at matrix openings one side and the conformal steel disc that is positioned at the matrix openings opposite side, and described conformal magnetic core is embedded in the described matrix, and described conformal steel disc is bonded on the described matrix.
The opening of described matrix tilts.
The angle of inclination of the opening of described matrix is 20～30 °.
Advantage and the good effect that the utlity model has are: the matrix adopting loop configuration, and the opening part distortion is less, has improved casting accuracy; Opening part adopts wedge shape to be connected with magnetic force, has improved the tightness of opening part, has further reduced the deflection of opening part, has improved casting accuracy; And easy to use, simple to operate, high efficiency.Also, make it can be suitable for the serial belt pulley of casting, have remarkable economical because the loose piece pattern matrix has pliability height and tool cutting.The utility model is fit to the large-scale belt pulley casting groove built-up pattern use of diameter greater than 400mm.
Description of drawings
Fig. 1 is the structural representation of the corresponding belt pulley breast wheel of the utility model cell wall;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of the corresponding belt pulley of the utility model two ends wheel cell wall;
Fig. 4 is the A-A cutaway view of Fig. 3.
Among the figure: 1, matrix, 2, the conformal steel disc, 3, the conformal magnetic core, 4, belt pulley matrix model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1～Fig. 2, the loose piece pattern of the large-scale belt pulley casting groove built-up pattern of corresponding belt pulley breast wheel cell wall, comprise the matrix of making by flexible material 1, described matrix 1 is for being provided with the annular of opening, the opening part of described matrix 1 is provided with close mechanism, and the shape of cross section of the shape of cross section of described matrix 1 and belt pulley breast wheel cell wall is adaptive.
Described close mechanism comprises magnetic core 3 that is positioned at opening one side and the conformal steel disc 2 that is positioned at the opening opposite side, described magnetic core 3 is embedded in the described matrix 1, described conformal steel disc 2 is bonded on the described matrix 1, and magnetic core 3 and conformal steel disc 2 are used to realize the opening closure of matrix 1.The opening of described matrix 1 preferably tilts, and the inclination angle is preferably 20～30 °, so that the tight closure of matrix 1 opening.
See also Fig. 3～Fig. 4; the loose piece pattern of the large-scale belt pulley casting groove built-up pattern of the corresponding belt pulley two ends wheel cell wall shown in Fig. 3～Fig. 4; the difference of casting the loose piece pattern of groove built-up pattern with the large-scale belt pulley of the corresponding belt pulley breast wheel cell wall shown in Fig. 1 and Fig. 2 is that the shape of cross section of the shape of cross section of loose piece pattern matrix and belt pulley two ends wheel cell wall is adaptive.Other structure is all with identical with the loose piece pattern of the large-scale belt pulley casting groove built-up pattern of the corresponding belt pulley breast wheel cell wall shown in Fig. 1 and Fig. 2.
The utility model is pressed the every increase of belt pulley external diameter 100mm, promptly based on flexible materials such as elastomeric materials
Deng, as an annular loose piece series, single cell wall is manufactured, moulded section.Then be assembled on the outer rim of belt pulley matrix model 4, though this moment, opening part existed variation in acceptable degree.Opening is obliquely installed, so that trip out the extraction of belt pulley matrix model 4 back loose piece patterns.Inlay with form height magnetic magnetic core 3 when opening one side adopts the vulcanization of rubber, opposite side adopts the thick conformal steel disc 2 of bonding 1.5mm.When installing, loose piece pattern, docks at opening part with the from bottom to top assembling one by one of single cell wall loose piece pattern.Extracting an end out along opening part when loose piece pattern is extracted out pulls out and gets final product.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
