Embodiment Construction

[0022] Such as figure 1 As shown, the aluminum alloy automobile wheel hub spinning preheating furnace of the present invention includes a furnace body. The furnace chamber in the furnace body is divided into upper and lower layers. Lower furnace door 4; the other end of the upper layer of the furnace chamber communicates with the other end of the lower layer of the furnace chamber;

[0023] There is a heat insulation layer between the upper and lower layers;

[0024] The upper layer of the furnace cavity is a preheating zone 9, and the lower layer of the furnace cavity is divided into a forced heating zone 8 and a heat preservation zone 7;

[0025] The exterior of the upper and lower furnace chambers is a combustion channel, which extends from one end of the furnace door along the length of the furnace body (that is, the horizontal direction in Figure 2); two high-temperature windmills 2 and multiple burners are arranged on the top of the combustion channel 1; Multiple burne...

Abstract

The invention discloses a spinning preheating furnace for an aluminum alloy automobile hub. The spinning preheating furnace comprises a furnace body, wherein a furnace cavity in the furnace body is partitioned into an upper layer and a lower layer; one end of the upper layer furnace cavity is provided with an upper furnace door; the same end of the lower layer furnace cavity is provided with a lower furnace door; the other end of the upper layer furnace cavity is communicated with the other end of the lower layer furnace cavity; the upper layer furnace cavity serves as a preheating area; the lower layer furnace cavity is partitioned into a forced heating area and a heat preserving area; combustion channels are formed outside the upper and the lower layers of furnace cavities; each combustion channel extends from one end of each furnace door along the length direction of the furnace body; the upper layer furnace cavity and the lower layer furnace cavity are provided with tracks respectively; the bottom of the furnace body is provided with an outer elevating frame; inner elevating frames are arranged in the upper layer furnace cavity and the lower layer furnace cavity; and the top of the combustion channel is provided with one or more high-temperature wind mills and a plurality of combustors. By adopting the spinning preheating furnace, a stable-temperature workpiece can be provided, heat energy can be utilized effectively, energy waste is reduced, and occupied space is reduced; and the spinning preheating furnace is convenient to operate, and is safe and environment-friendly for using.

Description

technical field [0001] The invention relates to an aluminum alloy automobile wheel spinning technology, in particular to an aluminum alloy automobile wheel spinning preheating furnace. Background technique [0002] Aluminum alloy automobile wheel hub spinning technology has been developed in recent years. Spinning products can bring considerable economic benefits, and are being applied in production by more and more manufacturers. [0003] The key step in spinning production is workpiece preheating, and the effect of preheating directly affects the entire production of spinning. In order to obtain a stable preheating effect, the preheating furnace needs to be designed to be very long, and the feeding and discharging are at both ends of the preheating furnace. However, because the preheating furnace is too long, it is inconvenient for operators to operate, which not only takes up space, but also wastes fuel and manpower. Contents of the invention [0004] The technical pr...
