Polyhead preform continue drawing machine

Abstract

The invention discloses a multiple head preform continuous drawing machine, which comprises a preform pre-straightening machine and a multiple head straight drawing machine, a multiple head pre-straightening mold is arranged on the preform pre-straightening machine, the multiple head straight drawing machine mainly consists of a multiple head straightening mold and a multiple head drawing mold which is matched with the multiple head straightening mold, and the multiple head drawing mold is arranged on a drawing sliding rack with a drive device. The drawing sliding rack slides to and fro along a machine frame, wherein the multiple head drawing mold 3 consists of a plurality of sets of drawing mold units, each drawing mold unit comprises two Half clamps, the Half clamps have inverted teeth inside, and clamp the pipe and slide along a dovetail groove on the drawing mold during the production. A guide rail is arranged on the machine frame, the guide rail is positioned on one side of the connecting line of the multiple head straightening mold and the multiple head drawing mold, thereby the side blanking can be achieved, and the destroy of the crash can be avoided. A shearing machine is arranged in front of the multiple head straightening mold and a synchronous speed inductor is arranged at back of the multiple head straightening mold. The multiple head straightening continuous production can be achieved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of nonferrous metal processing, in particular to the field of cold drawing of nonferrous metal pipes. Background technique [0002] At present, there are single-head continuous disc-shaped drawing and multi-head straight pipe drawing in China. The defect of single-head continuous drawing is that only one pipe can be drawn at a time, and the production efficiency is low. The defect of multi-head straight pulling is that it can only pull a pipe with a length of about 10m, and the yield is also very low, and it consumes a lot of manpower. And each time the head and the tail of the pipe will cut off a section that is in contact with the clamp, so as to obtain a pipe with better quality, resulting in a great waste of raw materials. Contents of the invention [0003] In order to solve the shortcomings in the prior art that single-head straight pulling can only pull one pipe at a time, production efficiency is low, multi-...
