Abstract

The invention discloses a composite stretch forming method for corrugated tube blanks. The method comprises the following steps: the tube blanks are sent to feeding blocks during forming, an upper machine board drives a servo motor linkage module to press downward, core rods drive the tube blanks to disengage from the feeding blocks and enter female die cavities, and stretch the tube blanks, downward pressing motion stops after the stretching motion is completed, then the servo motor linkage module rises and returns, a material returning block performs material returning motion to make the tube blanks disengage from the lower ends of the core rods when the tube blanks exist, and one stretching cycle is completed after the rising motion is completed; the servo motor linkage module rotates apreset angle after the last stretching cycle is completed, the core rods go forward for one station relative to female dies on a lower pedestal, and then stretching motion in the next cycle is carried out; and the tube blanks are stretched to reach a need thin wall state after cycle stretching motion is carried out with the frequency corresponding to the quantity of the female dies. The method greatly shortens the production period and increases the production efficiency, and the wall thickness of the produced seamless thin wall tube blanks has a good uniformity.

Description

technical field [0001] The invention relates to the technical field of metal bellows processing. Background technique [0002] The current production of seamless thin-walled tube blanks is mainly completed by multi-pass stretching. After each stretch, auxiliary processes such as cleaning and heat treatment must be carried out, and then the next stretching process is carried out. After multi-pass stretching Finally, the seamless thin-walled tube blank is produced. The whole process has a long production cycle, low efficiency, and poor uniformity of the wall thickness of the tube blank. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for compound drawing and forming of corrugated pipe blanks, which improves production efficiency and ensures the uniformity of the wall thickness of the tube blanks. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following...
