It adopts a continuous pusher design and uses a precise temperature control system to heat the aluminum alloy ingot evenly to meet the requirements of subsequent rolling or extrusion processes.
[0003] Early technical solutions mainly relied on manual operation or simple conveying mechanisms to load and propel aluminum ingots, which had problems such as uneven heating, low production efficiency, and high energy consumption. With the development of technology, they were gradually improved to automated propulsion systems, such as aerial return mechanisms. However, they still face limitations such as insufficient positioning accuracy (±10-15mm) and slow propulsion speed (0.3-0.5m / s). Furthermore, they lack intelligent temperature control and energy efficiency optimization functions, which restricts the improvement of efficiency in large-scale continuous production.

[0009] In a preferred embodiment of the rapid return mechanism for the material pad of the propulsion heating furnace described in this utility model, the bottom of the first moving frame is slidably connected to the top of the transverse trolley, and the outer surface of the first moving frame is fixedly connected to the rear end of the first hydraulic rod.
[0010] As a preferred embodiment of the material pad ground rapid return mechanism of the propulsion heating furnace of this utility model, the lifting assembly further includes a top plate, the bottom of which is fixedly connected to the top of the second hydraulic rod, and a placement frame is fixedly installed on the top of the top plate.
[0011] As a preferred embodiment of the material pad ground rapid return mechanism of the propulsion heating furnace of this utility model, the material picking mechanism includes a transfer cart, the bottom of which is slidably connected to the top of the longitudinal moving track, and a material pad is fixedly installed on the top of the transfer cart.
[0012] As a preferred embodiment of the material pad ground rapid return mechanism of the propulsion heating furnace of this utility model, the material picking mechanism further includes a No. 3 hydraulic cylinder, the outer surface of the No. 3 hydraulic cylinder is fixedly connected to the top of the longitudinal moving track through a fixed frame, the output end of the No. 3 hydraulic cylinder is fixedly mounted with a No. 3 hydraulic rod through a piston, the front end of the No. 3 hydraulic rod is fixedly mounted with a No. 2 moving frame, and the bottom end of the No. 2 moving frame is fixedly connected to the top of the transfer vehicle.
[0013] Compared with the prior art, the present invention has at least the following beneficial effects:
[0014] 1. This utility model improves the stability and speed of the material pad movement process through a design that enhances stability. It utilizes a lateral trolley and lateral moving track in conjunction with a connecting frame and a first hydraulic cylinder; a first hydraulic cylinder and a first hydraulic rod in conjunction with a first moving frame and a second hydraulic cylinder; and a second hydraulic cylinder and a second hydraulic rod in conjunction with a top plate and a placement frame. This achieves the return of the ground pad material using a rigid guide rail trolley mechanism, avoiding the swaying problem caused by the suspended structure in aerial mechanisms. The ground trolley moves in a straight line, achieving a propulsion speed of up to 0.75 m / s, which is 50% faster than non-linear aerial tracks. It eliminates the need for high-altitude lifting and lowering, reducing the single cycle time by 15-20 seconds.
[0015] 2. This utility model utilizes the combined use of the transverse moving component and the longitudinal moving track, as well as the combined use of the transfer car and the No. 3 hydraulic cylinder with the No. 3 hydraulic rod and the No. 2 moving frame. By taking advantage of the speed of the transverse moving component, it can be flexibly configured in combination with the special design of the transfer car on the longitudinal moving track of the material pad. This allows multiple furnaces to share the same set of mechanisms, thereby improving the utilization rate of the return mechanism and reducing the manufacturing cost of the entire train.
