Fast-mounted and dismounted replacement rod for expansion rod

Abstract

The invention discloses a fast-mounted and dismounted replacement rod for an expansion rod. The replacement rod comprises an expansion head assembly, a connecting rod and a lock rod which are connected in sequence; when the size of a product to be expanded is changed, or one assembly of the expansion head assembly, a rod body of the connecting rod and a rod body of the lock rod wears, the worn assembly can be immediately replaced, the remaining assemblies can be reused, so that materials are saved; the whole replacement rod can also be replaced, so that the influence on the production efficiency is greatly reduced, the use is convenient, and the mounting and dismounting efficiency is high; and for certain pipe bodies, with different lengths, required to be expanded, the connecting rods andthe lock rods with different lengths can be designed, the replacement rods with different lengths can be immediately replaced for use, so that expanding requirements of the pipe bodies with various lengths can be met, it is not needed to use special equipment or replace the expansion rod for processing, and the replacement rod is wider in applicability.

Description

technical field [0001] The invention relates to the technical field of pipe expansion equipment, in particular to a quick-loading, dismounting and replacing rod for expanding rods. Background technique [0002] In the production process of the pipe body, it is often necessary to expand the pipe body. When expanding the pipe, the expansion rod with the mouthpiece is inserted into the pipe body to expand the pipe. After long-term use, the expansion head of the expansion rod or Wear and tear in other parts needs to be replaced, but the existing expansion rod and the flaring head are designed as one, and the entire expansion rod needs to be replaced, especially for the expansion tube with a length of more than one meter, the entire replacement is a waste of material costs, and the expansion When expanding products with different sizes, it is necessary to replace all the expansion tubes on the expansion equipment. The replacement efficiency is low, time-consuming and labor-intens...

[0002] In the production process of the pipe body, it is often necessary to expand the pipe body. When expanding the pipe, the expansion rod with the mouthpiece is inserted into the pipe body to expand the pipe. After long-term use, the expansion head of the expansion rod or Wear and tear in other parts needs to be replaced, but the existing expansion rod and the flaring head are designed as one, and the entire expansion rod needs to be replaced, especially for the expansion tube with a length of more than one meter, the entire replacement is a waste of material costs, and the expansion When expanding products with different sizes, it is necessary to replace all the expansion tubes on the expansion equipment. The replacement efficiency is low, time-consuming and labor-intensive, and the length of the expansion rod is fixed, which cannot meet the needs of various lengths of tubes.
