Transverse automatic stretching device suitable for long-thin-wall pipe blank

Abstract

The invention discloses a transverse automatic stretching device suitable for a long-thin-wall pipe blank. The transverse automatic stretching device comprises an oil cylinder fixed to a workbench, abase and a guide column arranged between the oil cylinder and the base. The guide column is in sliding connection with a guide plate. The guide plate is connected with a male die and a piston rod of the oil cylinder. A female die is arranged in the base. The left side face of the base is connected with a feeding plate. The feeding plate is provided with a positioning sleeve corresponding to the female die. A feeding mechanism and a material return mechanism are further included. The feeding mechanism comprises a sliding block fixing plate arranged on the feeding plate, a feeding sliding blockcapable of sliding up and down along the sliding block fixing plate, a tension spring and a push plate which is in linkage with the guide plate, wherein the tension spring connects the feeding slidingblock with the sliding block fixing plate and constantly keeps the feeding sliding block with the downward sliding tension. The material return mechanism comprises a material return plate and a material return spring, wherein the material return plate is in sliding fit with the guide column and is located on the right side of the guide plate. According to the transverse automatic stretching device, one stretching action can be finished in each cycle, the middle pause time can be neglected, the production efficiency is high, and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of metal corrugated pipe processing, in particular to a transverse automatic stretching device suitable for long thin-walled pipe blanks. Background technique [0002] The current stretching method for long and thin-walled pipes is mainly to install the mold on the hydraulic stretching machine, place the die in the base and fix it on the stretching machine table, and fix the punch on the moving slider of the stretching machine. The tube billet to be stretched is put on the punch, and the stretching machine is urged to move the slider to run downward. The punch drives the tube blank down into the die for stretching. After the stretching is completed, the punch returns with The tube blank that has been stretched back is stuck by the upper stripping sleeve and starts to return the material. The moment the tube blank falls after the material is returned, the manual finger pushes the tube blank into the material ...
