Description

Technical Field

[0001] This utility model belongs to the technical field of mold steel ingot equipment, and particularly relates to a vacuum melting device for mold steel ingots. Background Technology

[0002] Vacuum induction melting furnaces utilize an alternating magnetic field generated by a medium-frequency power supply to induce a current in the metal charge. Due to the Joule heating effect, the metal charge rapidly heats up and melts. Melting in a vacuum environment effectively prevents the molten metal from reacting with oxygen, nitrogen, and other gases in the air, thus improving the purity and quality of the metal.

[0003] When the vacuum induction melting furnace is in operation, it can use atmospheric pressure to press the furnace door tightly. However, it still needs to be pre-locked during preparation so that the vacuum induction melting furnace can smoothly enter the vacuum state. Since conventional door locks require a separate unlocking action and a pulling action to open, the smoothness of opening conventional door locks is relatively low.

[0004] To address these issues, we propose a vacuum melting device for mold steel ingots. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the relatively low smoothness of conventional door lock opening, and to propose a vacuum melting device for mold steel ingots.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vacuum melting device for mold steel ingots includes a vacuum furnace and a furnace door. The furnace door is sway-mounted on the vacuum furnace. A fastening post is fixedly connected to the side of the vacuum furnace. A latching claw is rotatably mounted on the side of the furnace door. A limit strip abuts the outer side of the latching claw, and the limit strip is fixedly connected to the furnace door. A return spring is provided between the latching claw and the furnace door. The upper end of the return spring is fixedly connected to the latching claw, and the lower end of the return spring is fixedly connected to the furnace door. Pulling the latching claw outward at the front of the furnace door causes the rear part of the latching claw to retract inward and disengage from the fastening post, pressing the rear part of the latching claw against the side of the furnace door. The pulling force continues to act on the furnace door, opening it and improving the smoothness of opening the furnace door.

[0008] Preferably, a pusher is provided on the outer side of the latch, and the base of the pusher is fixedly connected to the furnace door. Pushing the pusher causes the furnace door to close, and the furnace door causes the latch to engage with the locking post, so that the latch and locking post are re-engaged, facilitating manual operation to close the furnace door.

[0009] Preferably, the latch includes a swing arm, one end of which is fixedly connected to a latch block. A rotating shaft is fixedly connected between the swing arm and the latch block. The rotating shaft is rotatably mounted on the furnace door. A return spring is sleeved on the rotating shaft, with its upper end fixedly connected to the rotating shaft and its lower end fixedly connected to the furnace door. The spring force of the return spring acts on the rotating shaft, which in turn acts on the latch block, keeping the latch block and the latching post engaged, thus facilitating the locking of the latch and the latching post.

[0010] Preferably, the latch also includes a handle, one end of which is fixedly connected to the end of the swing arm facing away from the latch block. By holding the handle and pulling it backward, the handle exerts an outward force on the swing arm, causing the swing arm to move the latch block towards the furnace door, thus disengaging the latch block from the fastening post. This allows the latch and fastening post to be easily released using the force of opening the door.

[0011] Preferably, the fastening post includes a fixing block, and a fastening frame is fixedly connected to the outside of the fixing block. The fastening frame and the fastening block are fastened together to facilitate the engagement of the fastening claw and the fastening post.

[0012] Preferably, the pusher includes a push plate, and a connecting plate is fixedly connected to the rear of the push plate. The rear end of the connecting plate is fixedly connected to the furnace door. Pushing the push plate backward causes it to act backward against the connecting plate, which in turn acts backward against the furnace door, closing the furnace door to the vacuum furnace and facilitating its closure.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Pull the latch outwards to the front part of the furnace door, causing the rear part of the latch to retract inwards and disengage from the fastening post. Press the rear part of the latch against the side of the furnace door, and use the pulling force to continue to act on the furnace door to open it, thus improving the smoothness of opening the furnace door.

[0015] 2. Push the pusher to close the furnace door, and the furnace door will cause the latch to engage with the fastening post, so that the latch and fastening post are re-engaged, making it convenient to manually close the furnace door.

[0016] 3. The spring force of the return spring acts on the rotating shaft, which in turn acts on the buckle block, keeping the buckle block and the buckling post locked together, making it easy for the buckle claw and the buckling post to remain locked.

[0017] 4. Hold the handle and pull it backward. The pull handle will exert an outward force on the swing arm, causing the swing arm to move the buckle block towards the furnace door, thus disengaging the buckle block from the fastening post. This makes it easier to use the force of opening the door to release the buckle claw and fastening post.

[0018] 5. Push the push plate backward, so that the push plate acts backward on the connecting plate, and the connecting plate acts backward on the furnace door, so that the furnace door and vacuum furnace are closed, making it easy to close the furnace door. Attached Figure Description
