Description

Technical Field

[0001] This utility model relates to the field of differential pressure casting technology, specifically to an automatic crucible furnace loading and unloading device. Background Technology

[0002] In differential pressure casting, the crucible furnaces holding molten aluminum need to be changed frequently. The original production line used a conventional aluminum changing cart, requiring manual hooking and unhooking of the crucible furnace each time it was pushed or pulled, impacting production rhythm and automation. Furthermore, the working environment was hot and dusty, with inherent instability and risks of operator injuries from crushing and molten aluminum burns, significantly affecting the physical and mental health of workers. This invention discloses an automatic crucible furnace hooking and unhooking device. This device ensures smooth hooking and unhooking, guaranteeing automated molten aluminum transport throughout the line. It can also be used on semi-automatic aluminum transport carts, allowing operators to control the relevant actions from the cab, replacing manual operation. This device ensures safe and stable crucible furnace changes, prevents molten aluminum from sloshing, reduces air bubbles, and guarantees molten aluminum quality. It also reduces the time and effort required by on-site personnel, speeds up crucible furnace changes, minimizes molten aluminum temperature loss, and improves production efficiency, providing strong support for cost reduction, efficiency improvement, energy conservation, and emission reduction in the entire differential pressure casting line.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is for reference. Figures 1 to 5 The automatic crucible furnace hanging and unloading device of this utility model is described in conjunction with the embodiments.

[0021] An automatic crucible furnace attachment / detachment device includes a push-pull furnace mechanism 1, an automatic crucible furnace attachment / detachment device 2, and a furnace body 3. The push-pull furnace mechanism 1 is fixed to the molten aluminum cart and serves as the power output and control unit for the crucible furnace's entry and exit from the differential pressure machine. The automatic crucible furnace attachment / detachment device 2 is fixed to a double-row chain on the push-pull furnace mechanism 1 and moves with the chain. It achieves automatic connection and disconnection between the molten aluminum cart and the crucible furnace via hooks 207. The furnace body 3 is the molten aluminum supply device for the differential pressure casting machine, and a furnace body hook wedge is installed at the front for connection to the automatic hook.

[0022] The push-pull furnace mechanism 1 includes a push-pull reduction motor 101, a sprocket and chain 102, a frame 103, a reduction and stop detection device 104, a travel guide rail device 105, and related accessories.

[0023] The crucible furnace automatic hanging and unhanging device 2 includes a mounting base 201, a motor mounting base 202, a hanging and unhanging control motor 203, a small pulley 204, a belt 205, a large pulley 206, a hook 207, a detection block 208, a front detection switch 209, a rear detection switch 210, a hook spindle 211, a furnace pusher rod 212, and related accessories.

[0024] The furnace body part 3 includes a crucible furnace 301, a furnace body hook wedge 302, a furnace body wheel assembly 303, and related accessories.

[0025] The furnace consists of a push-pull furnace mechanism 1, an automatic crucible furnace attachment / detachment device 2, and a furnace body 3. The push-pull furnace mechanism 1 is fixed to the molten aluminum cart and serves as the power output for the furnace. The automatic crucible furnace attachment / detachment device 2 is fixed to the double-row chain of the push-pull furnace mechanism 1 and moves with the chain. It connects and disconnects the molten aluminum cart from the crucible furnace via hooks 207. The furnace body 3 is the molten aluminum supply device for the differential pressure casting machine, with a furnace body hook wedge at the front that connects to the automatic hook.

[0026] The power output of the automatic hook-and-unhook device 2 for the crucible furnace is transmitted by the hook-and-unhook control motor 203 through the small pulley 204, belt 205, and large pulley 206 to the hook main shaft 211, controlling the rotation of the hook 207 to achieve the function of automatic hooking and unhooking. The tension of the belt 205 is adjusted by adjusting the motor mounting seat 202 with a set screw. The position of the hook unhooking is set by the front detection switch 209 and the rear detection switch 210 identifying the detection block 208. The entire mechanism is fixed on the mounting base 201. During the furnace pulling process, the hook 207 pulls the crucible furnace 3, and its force is applied to the hook main shaft 211, which has high strength and long service life. The furnace pushing is achieved by using the furnace pushing rod 212 to push the crucible furnace 3. The furnace pushing rod 212 is adjustable in position to ensure proper positioning and smooth overall operation.
