Description

Casting is with cutting hole frock

Technical Field

The utility model belongs to the technical field of the casting, concretely relates to casting is with cutting hole frock.

Background

In casting, the outer wall of some castings forms a bent arc-shaped long hole, most of the reasons are that cables need to penetrate from inside to outside or from outside to inside, because the outer wall of the castings has a thick wall, a long hole for the cables to penetrate through is formed between the inner surface and the outer surface of the outer wall, such as an outlet hole of a winch drum, the long hole is very small, when molten iron is poured, resin sand forming the long hole is sintered by high-temperature molten iron and cannot be separated from the castings, because the long hole to be processed is arc-shaped, the sintered resin sand cannot be drilled by a drill, and the sintered resin sand can be melted again at high temperature by a welding gun only to fall off the castings.

Disclosure of Invention

According to the defect that above-mentioned prior art exists, the utility model aims at providing a casting is with cutting hole frock can effectively realize the separation of resin sand and foundry goods in the cutting hole.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a cooling water box is arranged at a bent arc-shaped long hole of the outer wall of a casting, cooling water is filled in the cooling water box, the bottom surface of the cooling water box is the outer wall of the casting, and the cooling water is in direct contact with the outer wall of the casting.

Further, the cooling water box is welded on the outer wall of the casting.

Further, the cooling water box is welded on the outer wall of the casting in a spot welding mode.

Further, the cooling water box and the outer wall of the casting are sealed through yellow mud.

Further, the cooling water box and the outer wall of the casting are sealed through sealing mud.

Further, the two ends of the curved arc-shaped long hole are positioned on A, B two different surfaces of the outer wall of the casting, and the curved arc-shaped long hole extends from the surface A to the surface B of the outer wall of the casting.

Furthermore, the number of the cooling water boxes is two, the first cooling water box is arranged on the surface of the casting outer wall A, and the second cooling water box is arranged on the surface of the casting outer wall B.

Further, the arrangement direction of the cooling water box coincides with the extending direction of the curved arc-shaped long hole 4.

The utility model has the advantages that: the utility model discloses can realize the cooling to the foundry goods when cutting the hole through welder, make the resin sand of sintering can be melted by welder and break away from the foundry goods, make the foundry goods can not melted by welder simultaneously, guarantee the foundry goods quality.

Drawings

FIG. 1 is a schematic view of the present invention;

FIG. 2 is a schematic view of a winch drum;

FIG. 3 is a schematic view of a long hole to be processed of a winch drum;

in the figure: 1. the cooling water box comprises a casting outer wall, 2, a first cooling water box, 3, a second cooling water box, 4, a bent arc-shaped long hole, 5, a winch roller, 6, a cable, A, a casting outer wall surface A, and B, a casting outer wall surface B.

Detailed Description

In order to make the structure and function of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solution in the embodiments of the present invention.

Referring to fig. 1-3, taking the outlet hole of the winch drum as an example, the cable 6 of the winch drum needs to pass through the outer surface of the outer wall from the inner surface of the outer wall, and in order to match the installation of the winch drum 5 and the winding direction of the cable 6, a curved arc-shaped long hole 4 for the cable 6 to pass through needs to be cast on the outer wall of one side of the cast outlet wire. The utility model provides a casting is with cutting hole frock to above-mentioned condition, the crooked arc long hole department at hoist engine cylinder foundry goods wire hole sets up the cooling water box, the cooling water of packing into in the cooling water box, and the bottom surface of cooling water box is foundry goods outer wall, cooling water and foundry goods outer wall direct contact. The side wall of the cooling water box is welded on the outer wall of the casting in a spot welding mode, and the cooling water box and the outer wall of the casting are sealed through yellow mud, so that water leakage is prevented.

Further, two ends of the bent arc-shaped long hole 4 are positioned on two different surfaces of the outer wall of the casting, and the bent arc-shaped long hole extends from the surface A to the surface B of the outer wall of the casting. The cooling water box is two, and first cooling water box sets up on foundry goods outer wall A surface, and the second cooling water box sets up on foundry goods outer wall B surface.

Further, the yellow mud can be replaced by high-temperature-resistant sealing mud for sealing.

The utility model discloses when melting the resin sand of sintering through welder, can be through the cooling water to the cooling of foundry goods outer wall, prevent that the foundry goods outer wall from being melted by welder, guarantee the foundry goods quality.

The above list is only the preferred embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
