Description

Technical Field

[0001] This utility model relates to the field of metallurgy, and in particular to a device for fixed-point casting of large castings. Background Technology

[0002] Vacuum induction melting furnaces are primarily used for melting metallic materials (such as stainless steel, nickel-based alloys, copper, alloy steel, nickel-cobalt alloys, rare earth neodymium-iron-boron, etc.) under vacuum or protective atmosphere conditions. They can also be used for vacuum refining of alloy steel and precision casting. Eddy currents are generated during electromagnetic induction, causing the metal to melt. This process can be used to refine high-purity metals and alloys. Based on the type of material being melted, vacuum melting furnaces can be divided into master alloy melting furnaces and wrought alloy melting furnaces; based on furnace type, they can be divided into periodic furnaces and semi-continuous furnaces.

[0003] The casting process in a vacuum melting furnace takes place in a vacuum environment, making manual operation impossible. Accurate, precise casting requires mechanical control. The following technical issues need to be addressed in vacuum melting furnace casting:

[0004] 1. The vacuum melting furnace has no dedicated support structure for the melting chamber, making it difficult to maintain a uniform and fixed initial position of the furnace body. Long-term operation can easily cause changes in the angle of the furnace body, which is not conducive to production control.

[0005] 2. If the tilting height of the smelting furnace is insufficient, molten metal may remain in the furnace, resulting in insufficient casting. The residual molten metal may pose a safety hazard.

[0006] 3. The limited space inside the smelting chamber makes it difficult to complete the flipping process in a small space.

[0007] 4. The smelting furnace is relatively heavy, and the safety of its tipping needs to be improved. Utility Model Content

[0008] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0009] The technical problem to be solved by this utility model is to provide a device that can accurately control the tilting angle of the furnace body, is applicable to various molds, and can complete the fixed-point casting of large castings in the melting chamber under safe working conditions.

[0010] To solve the above-mentioned technical problems, the present invention provides a large-scale casting point casting device, which is arranged in the melting chamber of a vacuum induction melting furnace, and includes:

[0011] The base 1 has a movable tilting casting device 2 arranged on one side and a movable mold 3 arranged on the other side;

[0012] The mobile tilting casting device 2 can transport the melting furnace body 4 closer to or away from the mobile mold 3. When the melting furnace body 4 reaches the designated position, it drives the melting furnace body 4 to tilt so that the molten metal flows into the mobile mold.

[0013] The movable mold 3 can move horizontally to approach or move away from the movable tilting casting device 2;

[0014] The base 1 is divided into two parts. The first part 1.1 is used to arrange the movable tilting casting device 2, and the second part 1.2 is used to arrange the movable mold 3.

[0015] The first part 1.1 and the second part 1.2 of the base have a height difference, with the first part 1.1 being lower than the second part 1.2. This height difference helps to save space required for the transverse rotation of the smelting furnace body.

[0016] The base 1 forms a stepped structure, so that the movable tilting casting device 2 is located on the lower side, making the movable tilting casting device 2 suitable for molds of various heights and avoiding the safety hazards caused by the need for large-angle tilting of lower-height molds.

[0017] Preferably, the large casting fixed-point casting device, further improved by the movable flipping casting device 2, includes:

[0018] The first horizontal moving base 2.1 can be driven by the power source 2.2 to move horizontally closer to or away from the moving mold 3;

[0019] The power source 2.2 is fixed on the side wall of the melting chamber, and its output shaft is connected to the first horizontal moving base 2.1;

[0020] The smelting furnace body 4 is arranged on the tilting mechanism;

[0021] The flipping mechanism, which is fixed on the first horizontal moving base 2.1, can drive the melting furnace body 4 to flip to a designated position, so that the molten metal flows into the moving mold.

[0022] Preferably, the large casting point casting device, further improved by the flipping mechanism, includes:

[0023] Rotary connector 2.3 is fixedly connected to the outer wall of the melting furnace body 4 near the moving mold 3. Its first connecting end is the right end, and its first connecting end is pivotally connected to the top of the vertical support structure 2.4. Its second connecting end is spaced apart from its left end by a preset distance, and its second connecting end is pivotally connected to the top of the vertical drive unit 2.5.

[0024] A vertical support assembly is located at the bottom of the melting furnace body 4 on the opposite side of the rotating connector 2.3, and it is used to support the melting furnace body 4.

[0025] Preferably, the vertical support assembly of the improved large casting point casting device includes:

[0026] A vertical support column 2.6 has its bottom end pivotally connected to a first horizontally movable base 2.1;

[0027] The inclined telescopic column 2.7 has its bottom pivot connected to the first horizontal moving base 2.1 and its top pivot connected to the side of the vertical support column 2.6. It can telescopically move to make the vertical support column 2.6 tilt or be perpendicular to the first horizontal moving base 2.1 around its bottom pivot.

[0028] Preferably, the large casting fixed-point casting device is further improved such that the rotating connector 2.3 is formed as an L-shaped fixed connecting plate or a T-shaped fixed connecting plate;

[0029] The height of the connection point between the rotating connector 2.3 and the vertical drive unit 2.5 is lower than the height of the connection point between the rotating connector 2.3 and the vertical support structure 2.4.

[0030] Preferably, in a further improvement to the large casting point casting device, the movable mold 3 includes:

[0031] The second horizontal moving base 3.1 can be driven by a power source to move horizontally closer to or away from the moving and flipping casting device 2;

[0032] The mold 3.2 is fixed on the second horizontal moving base 3.1.

[0033] Preferably, the improved large casting point casting device further includes:

[0034] The first sensor, which is arranged on the side of the first part 1.1 of the base near the second part 1.2 of the base, is used to trigger the moving flipping casting device 2 to stop its horizontal movement near the moving mold 3;

[0035] The second sensor, which is located on the side of the second part 1.2 of the base near the first part 1.1 of the base, is used to trigger the moving mold 3 to stop its horizontal movement near the moving flipping casting device 2.

[0036] Preferably, in a further improvement of the large casting fixed-point casting device, the first sensor triggers the moving and tilting casting device 2 to stop horizontal movement and, after a delay, triggers the moving and tilting casting device 2 to drive the melting furnace body 4 to tilt so that the molten metal flows into the moving mold.

[0037] The working principle of this utility model is as follows:

[0038] In the initial state, the moving and flipping casting device and the moving mold are allowed to be in any position. By driving them to a fixed point, they can stay in any horizontal moving position and flipping position; after melting is completed, the casting action is started.

[0039] The mobile tilting casting device moves toward the mobile mold to a designated position, and at the same time the mobile mold moves toward the mobile tilting casting device to a designated position (this process can be manually controlled, controlled by a PLC, or controlled by a sensor-triggered position signal).

[0040] When the flipping operation is started, the horizontal position of the mobile casting device is fixed, and the vertical drive unit pushes the second connecting end of the rotating connector upward. The furnace body begins to flip around the first connecting end of the rotating connector. At the same time, the tilting telescopic column pulls the vertical support column away from the vertical support column to make way for the bottom of the furnace body until the molten casting material is poured out and flows into the mobile mold.

[0041] When the flipping and reset operation is started, the vertical drive unit pulls down the second connecting end of the rotating connector, and the furnace body begins to flip around the first connecting end of the rotating connector. At the same time, the tilting telescopic column pushes the vertical support column to reset in the vertical direction, and then the furnace body returns to the horizontal and is supported by the vertical support column.

[0042] This invention enables automatic linear tilting casting. The initial position of the furnace body does not need to be kept uniform and fixed; it can be arranged as needed. It achieves large-angle furnace tilting within the limited space of the melting chamber, preventing insufficient casting caused by molten metal residue in the furnace body. Furthermore, this invention improves production safety through fixed-point driving of horizontal movement and tilting positions. Attached Figure Description
