Description

Technical Field

[0001] The utility model relates to the technical field of steering wheel processing, in particular to a device for melting and feeding raw materials of a steering wheel skeleton. Background Art

[0002] In recent years, environmental and energy issues have become the focus, and magnesium alloys, as the lightest metal structural materials, have become a research hotspot. Among them, Mg-Al alloys are the most widely used die-cast magnesium alloys, and steering wheel frames are the most commonly used magnesium alloy die-castings.

[0003] At present, in the process of producing steering wheel frames, magnesium ingots are generally put into the furnace manually, which is very difficult in actual operation and management. Moreover, if the magnesium ingots are directly put into the furnace without being preheated and dried, it is very easy to cause the molten metal to splash, posing a safety hazard.

[0004] For example, the automatic feeding machine for melting raw materials of the steering wheel skeleton disclosed in Chinese patent CN208765488U places the magnesium ingot on the supporting plate, and the lifting plate drives the supporting plate to the set height. At this time, the height of the supporting plate is level with the height of the horizontal conveyor belt, and then the piston rod of the cylinder extends and drives the pushing plate to push the magnesium ingot on the supporting plate to the horizontal conveyor belt, and the horizontal conveyor belt transfers the magnesium ingot to the feeding chute for feeding; and, by setting a number of heating wires on the inner side of the dust cover, the magnesium ingot is fully preheated during the transmission process, avoiding the direct feeding of the magnesium ingot into the furnace without preheating and drying, which may cause the molten liquid to splash. In addition, by setting a universal wheel with a foot brake at the bottom of the mobile platform, the movement of the feeding machine is facilitated, and the maintenance of the feeding machine is facilitated, and the magnesium ingot can be effectively preheated, thereby eliminating safety hazards.

[0005] However, the device cannot adjust the height of the feeding chute during use. When the feeding port of the furnace is higher or lower than the feeding chute, the raw materials cannot be fed into the furnace, and the practicability is low.

[0006] For this reason, we urgently need to provide a steering wheel skeleton raw material melting and feeding device. Utility Model Content

[0012] Preferably, the preheating unit comprises a box heating wire, the box is installed on the top of the front and rear vertical plates, and the heating wire is installed inside the box.

[0013] Preferably, an internal thread that cooperates with the threaded rod is provided inside the connecting block, and the threaded rod is rotated to cooperate with the connecting block, thereby driving the support plate to move up and down along the support column, thereby achieving height adjustment of the blanking plate.

[0014] Preferably, the heating wire is connected to a power source via a conducting wire, and the heating wire is energized by the power source, so that the heating wire generates heat to preheat the magnesium ingot on the surface of the transmission belt.

[0015] Preferably, the threads on the outer sides of the two front and rear threaded rods are in opposite directions, so that the forces on the front and rear ends of the support plate are the same, which facilitates the support plate to move up and down along the support column.

[0016] Preferably, the support members are distributed at the bottom of the two top plates and the front and rear ends of the top of the base, and the threaded rod is fixed by two upper and lower adjacent support members.
