Abstract

The invention discloses a rotary heating and temperature control device in the combined spinning process of dissimilar metal and relates to the field of plastic composite forming of dissimilar metal. The rotary heating and temperature control device solves the problem existing in accurate temperature control over a central spindle and a tube blank in the combined spinning process of the dissimilar metal. According to the scheme, one end of a central spindle is connected with a central spindle collecting ring connector through a connector lug; a through hole used for allowing thermocouple wires and heating rod power wires to be placed therein is formed in the central spindle collecting ring connector; four collecting rings are fixed to the other end of the central spindle collecting ring connector, two of the four connecting rings are connected with the heating rod power wires, and the remaining two of the four connecting rings are connected with the thermocouple wires led in through the central spindle; the central spindle collecting rings are connected with a carbon brush holder in a compressed mode through springs on carbon brushes, so that an electric conduction effect is achieved; two carbon brushes enable a heating rod to be connected to the current output end of an intelligent temperature controller, and the remaining two carbon brushes enable the thermocouple wires to be connected to the feedback input end of the intelligent temperature controller. The rotary heating and temperature control device is used for rotary heating and temperature control in the combined spinning process of the dissimilar metal.

Description

technical field [0001] The invention relates to the field of plastic composite forming of dissimilar metal materials, and more specifically relates to a rotating heating and temperature control device for the composite spinning process of dissimilar metals. Background technique [0002] The development of the global low-carbon economy has put forward higher requirements for pipeline transportation technology in petrochemical, ocean development, nuclear energy utilization, household appliances and national defense industries. Compared with the traditional single metal pipe, the dissimilar metal composite pipe has the best properties of various base materials at the same time, such as high strength, high temperature resistance, corrosion resistance, wear resistance and other properties, and significantly reduces the use of precious metals and rare metals It can be widely used in transportation pipes, heat exchanger pipes, medical equipment pipes and other fields. In the manuf...
