Description

Technical Field

[0001] This utility model relates to the field of vacuum melting and casting technology, specifically to a feeding device for a three-chamber vacuum furnace used for melting and casting. Background Technology

[0002] A three-chamber vacuum casting furnace is a melting and casting device used in a vacuum environment. It mainly consists of a charging chamber, a melting chamber, and a casting chamber. In the entire process of the three-chamber vacuum casting furnace, the first step is to send the qualified master alloy to the second-level operating platform where the melting chamber is located, then send it to the charging chamber, and finally place it in the crucible for melting.

[0003] Traditional feeding methods mainly fall into two categories. One is manual operation, which becomes difficult when the required master alloy weight is large or there are many smelting batches. This not only consumes a lot of manpower and resources and has extremely low feeding efficiency, but also poses safety hazards during the process of moving the master alloy to the operating platform. The other method is to use a cantilever crane installed next to the vacuum furnace. This structure uses a motor to rotate and drive a chain or wire rope to move up and down to complete the feeding operation. It is a flexible connection, and the disadvantages of this device are: 1. The cantilever crane occupies a large space, which greatly reduces the utilization rate of the factory space and has certain requirements on the height of the factory, thus limiting its installation; 2. There are no protective measures around the crane, posing safety hazards. During the rise or fall of the master alloy bar, it will sway and shake, and there is even a possibility that the bar will be shaken off, causing a major safety accident. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a three-chamber vacuum furnace for melting and casting, which has the advantages of improving operating efficiency, high integration, reducing space occupation, reducing labor costs and increasing the safety of the feeding process.

[0006] Furthermore, a discharge chamber door is provided on the side of the discharge chamber facing the vacuum furnace.

[0007] Furthermore, support pillars are added at the four corners of the feeding channel, and the protective netting is fixed around the perimeter to a rectangular frame made of square steel pipes, with the rectangular frame connected to the support pillars.

[0008] Furthermore, the loading chamber door is hinged and a loading chamber door bolt is installed to connect the support column.

[0009] Furthermore, the feeding hole is located on one side of the sliding direction of the slide rail.

[0010] Furthermore, the wall thickness of the feeding hopper is 15mm, and the maximum weight of a single feeding is 200Kg.

[0011] This utility model has the following beneficial effects:

[0012] This utility model feeding device is integrated with a three-chamber vacuum melting furnace and is used for feeding alloy bars and recycled materials. It reduces the space occupied while improving feeding efficiency. During the feeding process, the mechanical hook can rise smoothly to avoid swaying and shaking, which greatly improves the stability of feeding and effectively prevents alloy bars from falling off and causing safety accidents. It also greatly improves the degree of automation and reduces labor costs. Attached Figure Description

Detailed Implementation

[0017] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a feeding device for a three-chamber vacuum furnace used for melting and casting.

[0018] like Figures 1-3As shown, a feeding device for a three-chamber vacuum furnace for casting is installed behind the second-level operating platform 1 where the melting chamber of the three-chamber vacuum casting furnace is located. The second-level operating platform 1 has a feeding hole 11. The feeding device includes an installation frame 2 set on the second-level operating platform 1. The upper part of the installation frame 2 is provided with a horizontal slide rail 21. A lifting device 3 is installed on the slide rail 21. The lifting device 3 can move left and right along the slide rail 21. A hook 31 is set on the lifting device 3. The hook 31 can move up and down. A protective net 4 is provided around the lower part of the feeding hole 11 to form a feeding channel. The bottom of the feeding channel is a feeding chamber 5. The feeding chamber 5 is provided with a feeding chamber door 51. A discharge bucket 6 that can be connected to the hook 31 is placed in the feeding chamber 5. The upper part of the feeding channel is a discharge chamber 7. The discharge chamber 7 is provided with a discharge chamber door 71 facing the vacuum furnace side.

[0019] The second-floor operating platform 1 is surrounded by a protective railing 12, and supported by pillars 8 at its base. Additional pillars 8 are installed at the four corners of the loading channel. The protective netting 4 is fixed to a rectangular frame made of square steel pipes, which is connected to the pillars 8. The loading chamber door 51 is hinged and secured with a bolt 52 to the pillars 8.

[0020] In this embodiment, the mounting frame 2 is a square frame composed of square steel pipes. The space within the square frame is the discharge chamber 7. Horizontal and diagonal reinforcing steel pipes 22 are installed on the side of the square frame away from the vacuum furnace. The slide rail 21 is made of I-beams, and the loading hole 11 is located on the sliding side of the slide rail 21. The lifting device 3 mainly includes a hoist and a hook 31. The hoist has a load capacity of 500 kg and can be remotely or wired controlled. The discharge bucket 6 has a wall thickness of 15 mm and a maximum single loading weight of 200 kg. The discharge bucket 6 is located inside the loading chamber 5.

[0021] When material needs to be loaded, control hook 31 is lowered to the loading chamber 5. After hook 31 is tightly connected to the discharge bin 6, the loading chamber door 51 is closed and the loading chamber door bolt 52 is tightened. Then, control hook 31 is adjusted to move through the loading channel, with a lifting height of 3.95 meters. The loading channel is protected by a protective net 4, which is reinforced with a rectangular frame around it, preventing personnel from entering and providing a layer of safety for the entire loading process. After the discharge bin 6 rises to the discharge chamber 7 of the second-floor operating platform 1, it is controlled to move to the right through the loading hole 11 and placed on the second-floor operating platform 1 to await material loading.

[0022] The lifting device can move the material bucket 6 up, down, left, and right as a whole, and can safely and quickly send the alloy rod to the second-level operating platform 1 of the three-chamber vacuum melting furnace, avoiding secondary movement and greatly reducing labor costs.
