Embodiment
The purpose of this utility model, technical scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.Should be appreciated that the embodiment of describing in this specification sheets only is in order to explain the utility model, is not in order to limit the utility model.
See also Fig. 1 to shown in Figure 3, the utility model air device 10 can be connected the end face of extrusion machine 60, in order to the workpiece 70 (for example, can be aluminium section bar or other non-ferrous metal section bars) of online cooling moulding from extrusion machine 60.The utility model air device 10 comprises support oriented device 20, centers on the sealing-duct 30 of support oriented device 20, is sealedly connected on the steering knuckle 40 on the extrusion machine 60, and sealing is installed in the extractor fan 50 on the steering knuckle 40.
Several parallel rollers 204 on support oriented device 20 comprises support 202 and is distributed in support 202, the workpiece 70 of moulding on the self compaction machine 60 can be derived through support oriented device 20.
Sealing-duct 30 be centered around support oriented device 20 roller 204 around, it is the open closed conduct of an end.Sealing-duct 30 is sealedly connected on the 3rd opening (not shown) of steering knuckle 40 near an end of extrusion machines 60, is opening end away from an end of extrusion machine 60.In illustrated embodiment, sealing-duct 30 comprises the fixed housing 302 that is fixed on the support 202 and is fastened on movable shell 304 on the fixed housing 302 movably, one side of fixed housing 302 and movable shell 304 is connected by hinge 305, and opposite side stably snaps together and form the cavity of a sealing by handle 306.The workpiece 70 of moulding can advance in sealing-duct 30, and self compaction machine 60 moves to the opening end of sealing-duct 30 under the guiding of support oriented device 20, and is subjected to the cooling of wind in sealing-duct 30.
