Abstract
The invention relates to a method for preparing a heat insulation partition for an automobile exhaust pipe, comprising: step S1, adding raw materials into a melting and casting machine according to the proportion of raw materials, and a central control unit starts the melting and casting machine to prepare aluminum plates; step S2, the central control unit Start the transmission device to transport the aluminum plate in step S1 to the hot rolling mill for hot rolling; step S3, the central control unit transports the hot rolled aluminum plate in step S2 to the cold rolling mill for cold rolling; step S4, the The cold-rolled aluminum plate is embossed; in step S4, the surface of the embossed aluminum plate is subjected to anti-corrosion treatment, and the real-time monitoring of the process of processing the heat insulation partition by the central control unit can make the prepared automobile exhaust pipe The thickness of the heat insulation partition meets the standard, and at the same time, through the preparation method of the present invention, the heat dissipation area of the prepared heat insulation partition is larger, and the heat dissipation capacity of the heat insulation partition is increased.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a heat insulation partition for an exhaust pipe of an automobile and a preparation method thereof. Background technique [0002] The automobile exhaust pipe heat insulation partition is used to insulate the automobile exhaust pipe and the automobile floor. Because it is often in the environment of high temperature and corrosive gas, it is easy to cause damage. However, in the prior art, in the preparation The extrusion pressure of the cold-rolling mill and the hot-rolling mill is insufficiently controlled by the thermal insulation partition of the automobile exhaust pipe, and the thickness of the thermal insulation partition of the automobile exhaust pipe prepared is uneven and the quality is poor. Contents of the invention [0003] For this reason, the present invention provides a kind of heat insulation partition preparation method of automobile exhaust pipe, in order to o...
