Problems solved by technology

[0004] However, during the production of the slider through the casting process, the cooling oil pipe needs to be pre-embedded in the mold, but the cooling oil pipe is prone to float and shift during the pouring of the high-temperature molten iron (molten iron) of the casting raw material; The air in the buried cooling oil pipe will expand instantly under the action of high-temperature molten liquid, and if the measures are not taken properly, major accidents such as explosions will occur, which will cause danger to operators

Embodiment 1

[0064] (1) The raw material of following mass percentage is taken: 40% of pig iron, steel scrap 35%, 25% of returned charge, carburizer: 0.9% of the total amount of pig iron, scrap steel, returned charge;

[0065] (2) Put all the pig iron and steel scrap into the smelting furnace, then add 0.9% carburant of the formula total amount; heating makes the charge melt, and after the charge is melted, add FeSi75-C ferrosilicon, the addition of ferrosilicon is 0.75% of the total mass of pig iron, scrap steel and returned materials to obtain the original molten iron, and continue to heat the original molten iron to 1490°C; the composition and mass percentage of the obtained original molten iron are C 3.58%, Si 1.45%, Mn0.24 %, P0.035%, S 0.023%, the rest is iron;

[0066] (3) The spheroidization is carried out by the flushing method. The spheroidizing dam on one side of the spheroidizing bag is firstly added with a spheroidizer and compacted, and then an inoculant with a particle size ...

Embodiment 2

[0080] (1) The raw materials of the following mass percentages are weighed: 35% of pig iron, 35% of steel scrap, 30% of recharge, recarburizer: 1.0% of the total amount of pig iron, scrap, and recycle;

[0081] (2) Put all the pig iron and steel scrap into the smelting furnace, then add a carburant with a total formula of 1.0%; heat to melt the charge, and add FeSi75-C ferrosilicon after the charge is melted, and the amount of ferrosilicon added is 0.67% of the total mass of pig iron, scrap steel and returned materials to obtain the original molten iron, and continue to heat the original molten iron to 1490°C; the composition and mass percentage of the obtained original molten iron are C 3.55%, Si 1.50%, Mn0.22 %, P0.033%, S 0.025%, the rest is iron;

[0082] (3) The spheroidization is carried out by the flushing method. The spheroidizing dam on one side of the spheroidizing bag is firstly added with a spheroidizer and compacted, and then an inoculant with a particle size of 3...

Abstract

Provided are a fixing structure for an embedded cooling oil tube, a casting system and a casting method. The fixing structure comprises the embedded cooling oil tube embedded into a casting mold of asliding block casting, and the embedded cooling oil tube is provided with an oil inlet and an oil outlet. The embedded cooling oil tube is in a rectangular bend shape and extends in the length direction of the casting. The oil inlet and the oil outlet of the embedded cooling oil tube are close to each other and are spaced. Positioning rebars and anti-deformation tie bars are arranged on the embedded cooling oil tube, and space is reserved on the casting. The anti-deformation tie bars comprise a first anti-deformation tie bar and a second anti-deformation tie bar, the first anti-deformation tiebar is fixed between the oil inlet and the oil outlet, and the second anti-deformation tie bar is fixed between the long edges of two oppositely arranged embedded cooling oil tubes in the width direction of a rectangular ben. The positioning rebars are parallel to the oil inlet and the oil outlet, one end of each positioning rebar is connected with the embedded cooling oil tube, and the other endof the positioning rebar extends out of the surface of a cavity of the sliding block casting. The fixing structure for an embedded cooling oil tube, the casting system and the casting method have theadvantages that floating or shifting is not likely to happen, and explosions are avoided.

Description

technical field [0001] The invention relates to the technical field of preparation of castings containing embedded parts, in particular to a fixing structure for embedded cooling oil pipes, a casting system and a casting method. Background technique [0002] The high-speed punch press has a fast stamping speed, and the number of strokes per minute can reach 1200 times / min, which is 5-10 times the production efficiency of ordinary punch presses. The high-speed punching machine is rotated by the crankshaft, and then the connecting rod on the crankshaft drives the slider to reciprocate downward to complete the punching production. The moving parts will destroy the normal gap due to thermal expansion, or the lubricating oil will be stuck due to the failure of the lubricating oil at high temperature. Parts will reduce their mechanical strength or even be damaged due to high temperature. Therefore, in order to ensure the normal operation of the engine, the parts working under hig...
