Problems solved by technology

The disadvantages are: different cavities are required to extrude products with large differences in size and specifications. When extruding different products with the same cavity, it will bring extrusion load to some products. The high temperature of the Yamato stopper block causes premature damage to the cavity, reduces the service life of the cavity, and increases production costs

Embodiment Construction

[0012] A continuous extrusion method with preforming for non-ferrous metals. After the billet enters the feeding port of the cavity, it is preformed first, that is, the preformed billet is extruded into a product through a die.

[0013] The device adopted is that an extrusion wheel 10 with a circumferential groove 11 is installed on the rotating shaft 9, a mold 3 is installed on the cavity 1, a preformed part 2 is housed on the cavity in front of the mold 3, and a preformed part 2 is installed on the mold outlet 5 There is a support pad 4 on the cavity at the back. According to the present invention, between the cavity inlet 6 and the sizing outlet 5 of the mold 3, there is a molding zone 12, due to the variation of the size of this area, from the center point 7 of the cavity inlet to the mold surface 5 The distance H varies according to different products and the thickness of the mold 3 . On a certain cavity 1, when different products are extruded, the size H is changed. Whe...

Abstract

The present invention relates to metal extruding method, and is especially continuous extrusion method with pre-formation. The method is that the blank after entering into the feeding port of the cavity is first preformed and then extruded into the product. Before the extruding mold, there is one performing area in sizes changing with the sizes of the extruded products. The present invention makes it possible to obtain products of different sizes in the same cavity, to reduce the load on the cavity, lower the temperature of cavity stopper, raise the production efficiency of the cavity and increase the service life of the cavity greatly.

Description

Technical field: [0001] The invention relates to a method for manufacturing non-ferrous metal products such as copper and aluminum busbars, ladder bars, copper flat wires and various bars, and also provides special equipment for the production. Background technique: [0002] The current method for continuous extrusion of copper and aluminum all adopts a given cavity, and the external dimensions of the installed molds are fixed. Regardless of the production of products of any specifications, molds with the same thickness and dimensions are used. The disadvantages are: different cavities are required to extrude products with large differences in size and specifications. When extruding different products with the same cavity, it will bring extrusion load to some products. The high temperature of the Yamato blocking block causes premature damage to the cavity, reduces the service life of the cavity, and increases production costs. Invention content: [0003] The purpose of th...
