High-frequency vibration wire rod straightening device and using method thereof

Abstract

The invention discloses a high-frequency vibration wire rod straightening device and a using method thereof. The high-frequency vibration wire rod straightening device comprises a casing and at least two groups of clamping devices, wherein each group of clamping devices comprises a first clamping unit and a second clamping unit. The first clamping unit comprises a first mold, a spring clamping ring, a bearing and a pressing end cover, the second clamping unit comprises a second mold, a spring clamping ring, a bearing and a pressing end cover, the first mold sleeves a distance adjusting shaft, the second mold sleeves a high-frequency vibration shaft, the lower portions of the first mold and the second mold are provided with bosses, the bearings, the spring clamping rings and the pressing end covers are sequentially arranged on the bosses, and the high-frequency vibration shaft is connected with a high-frequency vibration motor. The wire rod straightening is achieved by replacing the molds to straighten wire rods different in diameter and adjusting a distance between the centers of the molds to compensate mold abrasion. Most of stress of straightened materials is quickly eliminated through high-frequency vibration force, the wire rod straightening efficiency and quality are improved, straightening of wire rods different in material and diameter is achieved, and economic benefits of products is improved.

Description

technical field [0001] The invention relates to a wire straightening device, in particular to a high-frequency vibration wire straightening device and a use method thereof. Background technique [0002] Chains or pipes of various sizes made of carbon steel and stainless steel are ubiquitous in our lives. Chains made of materials with larger wire diameters are mostly used for anchor chains of ships; chains (or steel pipes) made of materials with general wire diameters can be used for zippers (beds of health care beds) of electric hoists, work? Or the chain of the rolling shutter door of the shopping mall, etc. The chains made of small-sized stainless steel wire diameters are widely used as guardrail chains (or guardrails for health care beds) on the embankment side guard piles; they can be worn on bags and clothes as decorations, adding fashion A charm; can also be used to tie pets, adding a fun to life. Chains or health beds have played an integral role in our lives. [...

AI Technical Summary

Problems solved by technology

Because carbon steel or stainless steel has a certain strength and toughness, it is not easy to be straightened instantly. Small-sized stainless steel wires (or steel pipes) have good plasticity, but their material retention is not good after being straightened.

The existing iron chain (or steel pipe) production equipment uses the wire rod (or steel pipe) to pass between the two rollers to straighten the wire rod (or steel pipe). For materials with larger wire diameters, the straightening strength is not enough. The residual stress of the finished material is large and easy to rebound, which affects product quality to varying degrees

At the same time, the two rollers are greatly consumed by the wear and tear of the wire rod for a long time. Frequent replacement of the rollers will not only affect production but also increase production costs. Failure to replace the rollers in time will affect the straightening quality of the wire rod, thereby affecting the quality of the product.
