Abstract
The utility model discloses a template mould for casting tin-base alloy bushes, which is characterized in that the template mould for casting tin-base alloy bushes is composed of the butt joint of a casting surface template and a back lining template; the edges of the two templates are provided with a plurality of fastening holes; the inner sides of the fastening holes are provided with fastening screws; the casting surface template is provided with a casting hole; a junction surface between the casting surface template and the back lining template is a liquid tight fit. Making use of the casting surface template, the template mould for casting tin-base alloy bushes obtains the thickness control of a casting layer, reduces processing amount, enhances the smooth finish of casting surface, and is favorable to detect the bond quality of the casting layer. The utility model has the advantage of simple structure, and is particularly suitable for casting tin-base alloy bushes.
Description
The utility model relates to the fabrication tool of machine driving bearing shell, particularly is used for the template mold of Sn-based alloy bearing bush casting.
Machine driving bearing shell (sliding bearing) is widely used in heavy duty and the mechanical transmission component that runs up in electric power, chemical industry, metallurgical production and manufacturing enterprise, also is mechanically operated easily worn part.
The quality of the casting bonding quality of various big machinery power transmission shaft pad bearing alloys directly influences the safe handling of gearing and the service life of bearing shell.The bearing shell of domestic production at present adopts traditional casting process mostly, and promptly at wear-resisting, the exotic material of back lining materials top casting one deck, Sillim's alloy is exactly a kind of bush material that is used for main equipment.Radially bearing shell (cylindrical shape bearing shell) adopts spun casting mostly, and the plane thrust bearing shoe adopts static casting, and the thickness of cast layer leans on how many decisions of cast material fully.The thickness of cast layer can not accurately be controlled, and often surpassing needs thickness a lot; Mould surface is rough, can not be directly from this surface with bonding quality between ultrasound examination it and the backing.
The purpose of this utility model provides a kind of template mold that is specifically designed to casting Sn-based alloy bearing bush layer, can control casting thickness, makes casting face smooth.
For achieving the above object, the technical solution of the utility model is: it is formed by casting face die plate and the butt joint of backing face die plate, at the edge of described two templates several fastener holes are arranged, in this fastener hole trip bolt is arranged, tapping hole is arranged in casting on the face die plate, the faying face between two templates is that liquid sealing cooperates.
Described casting face die plate and be dull and stereotyped; Described backing template is a box body, and the cavity shape of box also is writing board shape, and is identical with the backing shape, and its medial surface is that liquid sealing cooperates with the backing side that needs casting plane bearing shell.
Described casting face die plate is a cylinder, its length is identical with backing length, end at this cylinder connects a disk, described backing template is cylindric, its internal diameter is identical with the external diameter of backing, and its length is identical with described cylinder length, and an end of described cylinder is what seal, two templates are nested together, and each faying face is that liquid sealing cooperates.
Described cylinder is a hollow cylinder.
The smooth surface of the inner face of described casting face die plate.
The utlity model has following advantage:
1, can control the thickness of cast layer with template, compare, can reduce the casting amount of bearing alloy, avoid the cast material waste that causes of reuse repeatedly, improve work efficiency with traditional casting method.
2, mould surface is smooth, can be directly from the bonding quality of this face with ultrasound examination casting face and backing.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a prior art casting schematic diagram;
Fig. 2 is embodiment of the utility model, the structural representation of plane bearing shell template mold;
Fig. 3 is another embodiment of the present utility model, radially bearing shell template mold structural representation.
As shown in Figure 1 be the plane bearing shell schematic construction of conventional method casting, at backing 1 top casting alloy material 1, baffle plate 3 is arranged in the side, the upper surface of this cast layer 1 opens wide, cast layer is solidified and has just been formed the bearing shell layer; For bearing shell radially, cast alloys material in the tubular backing of rotation, the cooling back forms the bearing shell layer in backing, and its inner surface also opens wide.
Referring to Fig. 2, be an embodiment of the present utility model, be the structural representation of plane bearing shell template mold, described casting face die plate 4 is dull and stereotyped; Described backing template 5 is a box body, the cavity shape of box also is writing board shape, and is identical with the shape of backing 1, and its medial surface is that liquid sealing cooperates with backing 1 side that needs casting plane bearing shell, on casting face die plate 4, have between tapping hole 7, two templates and tighten with screw 6.
Referring to Fig. 3, be another embodiment of the present utility model, be the structural representation of bearing shell template mold radially.Described casting face die plate is cylinder 8 (also can be cylinder), and the disk 9 of end connection at this cylinder has tapping hole 7 on its end 11.Described backing template is a cylinder 10, and its internal diameter is identical with the external diameter of backing 1, and its length is identical with described cylinder 8 length, is blind end 11 at an end of described cylinder 10.Two templates are nested together, and are fastening with screw 6.Each faying face is that liquid sealing cooperates.
The utility model is mainly used in the Sn-based alloy bearing bush casting, also relates to casting process, welding process and ultrasound examination test block in using the utility model process.
