Detailed Description
The invention is described in further detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 3, the brake caliper includes a caliper body 1 and a bracket 2, the caliper body 1 and the bracket 2 are formed by casting, and the brake caliper is characterized in that: before the casting process, as shown in fig. 2 and 4, the supporting net racks 4 are connected through the cores 3 to form an assembly, and in an embodiment, a plurality of cores 3 are connected through one supporting net rack 4 to form an assembly for reducing weight. The combined part is placed in a casting-formed sandbox and occupies the interior of the structure of the clamp body 1/the bracket 2, then the sandbox is poured with molten iron, and the clamp body 1/the bracket 2 are integrally cast and formed, so that the purpose of reducing weight of a finished product is achieved. Thereby passing through the density difference between the casting and the loam core (difference up to 5.4 g/cm)3) Thereby achieving the purpose of reducing weight of the hollow inner cavity in the clamp body and the bracket.
The hollow part of the clamp body 1/bracket 2 structure which can remove weight is filled with the sand core 3, so that the weight is reduced conveniently, and after the combined piece is placed in a casting molding sandbox, the sand core 3 is supported and arranged through the supporting net rack 4. The clamp body and the bracket can be embedded and filled by a loam core at the position with low structural strength requirement or the position of the internal space of removable material, so that the weight of the finished product of the clamp body and the bracket is effectively reduced.
The supporting net rack 4 is supported in the sandbox for manufacturing the clamp body 1/bracket 2, so that the hollow part of the finished product part is prevented from being communicated with the outside, and the inside corrosion is avoided. After casting and forming, the mud core 3 is not exposed outside the clamp body 1/bracket 2, and the supporting net rack 4 is arranged by penetrating through the clamp body 1/bracket 2.
The density of the loam core 3 is lower than that of the clamp body 1/the bracket 2, and the supporting net rack 4 is made of a material which can resist the high temperature of more than 1600 ℃, preferably a high-temperature-resistant ceramic material or a high-temperature-resistant metal material.
Example 1, fabrication of clip:
the sand core 3 is a light sand core material commonly used in casting, the supporting net racks 4 are made of high-temperature-resistant materials, such as ceramics or high-temperature-resistant metals, the two sand cores 3 are connected in a penetrating mode through the two supporting net racks 4 to form a combined piece, as shown in fig. 2, the two sand cores 3 are respectively arranged on two sides of the clamp body, and as shown in fig. 1, the combined piece is placed in a sand box and then poured and cast.
In the pouring process, the mud core 3 is suspended and fixed in the sand cavity by the supporting net rack 4, so that the purpose of reducing the weight inside the clamp body is achieved.
After the finished product of the clamp body blank is finished, the supporting net rack 4 is cut and polished at the exposed part of the clamp body through post-treatment, and meanwhile, the net rack and the finished product are integrated to ensure the sealing of the inner cavity where the filling loam core 3 is positioned.
Example 2, scaffold fabrication:
the sand cores 3 are made of light sand core materials commonly used in casting, the supporting net racks 4 are made of high-temperature-resistant materials, such as ceramics or high-temperature-resistant metals, the three sand cores 3 are connected in a penetrating mode through the supporting net racks 4 to form combined parts, as shown in fig. 4, the three sand cores 3 are respectively arranged in the middle and two sides of the clamp body, more supporting net racks 4 are arranged outside the sand cores 3 on the two sides, and as shown in fig. 3, the combined parts are placed in a sand box and then cast.
In the pouring process, the mud core 3 is suspended and fixed in the sand cavity by the supporting net rack 4, so that the purpose of reducing the weight inside the bracket is achieved.
After the finished support blank is finished, the supporting net rack 4 is cut and polished at the exposed part of the support through post-treatment, and meanwhile, the net rack and the finished product are integrated to ensure the sealing of the inner cavity where the filling loam core 3 is positioned.
The specific implementation and manufacturing process of the invention is as follows:
the clamp body 1 and the support 2 are weight-reduced components, wherein the sand core 3 is a main added component and plays a key role in reducing weight, the support net rack 4 is a support auxiliary component adopted for realizing the process, the sand core 3 is suspended and restrained in a molding cavity by the support net rack 4, the support net rack 4 and the sand core 3 can not be melted and deformed in the molten iron pouring process, and after the clamp body 1 and the support 2 are molded, the part of the support net rack 4 extending out of the clamp body is cut off through post-processing.
Therefore, the invention can effectively reduce the mass of the caliper body and the bracket part in the brake caliper assembly, thereby reducing the weight of the brake caliper assembly, lightening the unsprung mass of the whole vehicle, being beneficial to the controllability, the comfort and the acceleration of the vehicle, and reducing the oil consumption and the exhaust emission.
