Problems solved by technology

In this way, the amount of nitrogen used is very large, resulting in increased production costs, and filling the chassis with nitrogen does not completely prevent oxidation
[0003] After research, in the production process, the only thing that really protects the copper tube is the nitrogen surrounding the rolling head, and the rest of the nitrogen is wasted in vain and has no real effect

Embodiment Construction

[0017] Such as figure 1 , figure 2 with image 3 As shown, it is an embodiment of the nitrogen protection throttling device for a planetary rolling mill of the present invention, including a throttling ring pipe 1, and a plurality of airflow outlets 2 are arranged on both side walls of the throttling ring pipe 1 in the axial direction, and the airflow outlets 2 face The direction of the axis of the throttle ring (such as image 3 ), the throttle ring pipe is also provided with a connecting pipe 3 for communicating with an external air source, the connecting pipe extends outward from the outer ring wall of the throttle ring pipe 1, and the outer end of the connecting pipe is bent to form a connection with the throttle ring A bent portion 4 parallel to the axis of the tube. The throttling ring tube in this embodiment is a round tube, and may also be a square tube, an oval tube or a polygonal tube. In this embodiment, the connecting pipes are two centrally symmetrically arra...

Abstract

The invention discloses a planetary mill nitrogen protection throttling device comprising a throttling circular pipe. Both side walls of the throttling circular pipe are respectively provided with a plurality of air outlets facing the axis line direction, and the throttling circular pipe is also provided with a joint pipe for communicating an external gas source. The planetary mill nitrogen protection throttling device has the advantages of reasonable design, simple structure, convenient operation and remarkable effect and saves consumption amount of nitrogen.

Description

technical field [0001] The invention relates to a nitrogen protection throttling device inside a rolling head of a copper tube planetary rolling mill, and belongs to the technical field of metal processing equipment manufacturing. Background technique [0002] With the increasingly tense energy supply, people from all walks of life are calling for energy saving. The planetary rolling mill is one of the rolling equipment in the process of copper tube processing. During the rolling process of the planetary rolling mill, the temperature of the copper tube reaches 600-700°C. If it is in contact with air, it is easy to oxidize and turn black, which will affect the quality and sales price of the copper tube. In order to prevent the oxidation of the copper tube, the rolling mill box is generally filled with nitrogen to isolate the air. In this way, the amount of nitrogen used is very large, resulting in increased production costs, and filling the case with nitrogen does not comple...
