Rolling and drawing joint production equipment for profiled material products, and rolling and drawing production technology thereof

Abstract

The invention discloses rolling and drawing joint production equipment for profiled material products, and a rolling and drawing production technology thereof. The production equipment comprises a guiding device, a rolling mill, a drawing machine and an auxiliary device, and the rolling mill is a two-pass continuous rolling mill, and comprises a first rolling group, a second rolling group, a thirdrolling group and a fourth rolling group, wherein a first rolling pass is formed by the first rolling group and the second rolling group, and a second rolling pass is formed by the third rolling group and the fourth rolling group; and the prototype of a workpiece is controlled by the rolling mill; the drawing machine is a continuous drawing machine, and comprises a first drawing group and a second drawing group which are located at a first drawing pass and a second drawing pass separately; and the drawing machine further comprises front and rear drawing trolleys and a box body. The rolling and drawing production technology comprises the steps of two times of continuous rolling by the first pass, annealing, two times of continuous rolling by the second pass, annealing, drawing on the firstpass, drawing on the second pass and so forth, so that the profiled material products are obtained.

Description

technical field [0001] The invention relates to the field of mobile phone component manufacturing, in particular to rolling-drawing combined production equipment and a rolling-drawing production process for special-shaped products. Background technique [0002] At present, the production process of special-shaped products is a simple drawing process. This process refers to pulling the metal blank from the die hole smaller than the section of the blank under the action of external tension, so that it can be plastically deformed to obtain the corresponding size. A plastic processing method for shape and shape. In order to obtain qualified size, shape, mechanical properties and surface quality of drawn products, it is generally necessary to draw the drawn blank multiple times. Because metal blanks will have changes in hardness and surface quality due to changes in the metallographic structure of the material during the drawing process, it is necessary to add an annealing proce...

Problems solved by technology

However, this process is limited by the amount of deformation per pass and the total deformation between two annealings, which indirectly reduces production efficiency
