An automatic measuring mechanism for steel bar straightening and cutting equipment

Abstract

The invention discloses an automatic scale measure mechanism for steel bar straightening and cutoff equipment, belonging to the technical field of automatic strengthening and cutoff of disc steel bars. A scale measure wheel of the automatic scale measure mechanism is connected in a flexible fixation manner, the selection direction of a single steel material at the present stage is abandoned, the habitual thoughts about material selection of the traditional scale measure wheel are overcome, and a dismountable structure which adopts combination of a soft nonmetal material friction sleeve belt and a hard base wheel is creatively provided; during work, the friction sleeve belt can be rapidly replaced in the case of abrasion, which is not like the manner that the overall traditional scale measure wheel needs to be replaced in the case of abrasion, thus the use cost of the scale measure wheel is greatly lowered; when the friction sleeve belt is in contact with a steel bar moving at high speed, a high friction coefficient between the friction sleeve belt and the steel bar can be guaranteed, thus slip phenomenon is farthest reduced, and the automatic scale measure mechanism has a quite high sizing accuracy. The automatic scale measure mechanism disclosed by the invention solves the problems of abrasion, slip and sizing accuracy that cannot be solved by the existing high-cost technologies with low cost, and changes the development direction of the technical field of the current steel bar strengthening and cutoff.

Description

technical field [0001] The invention belongs to the technical field of automatic straightening and cutting of round (or spiral) steel bars, and in particular relates to an automatic ruler detection mechanism for straightening and cutting equipment of steel bars. Background technique [0002] With the rapid development of the construction industry, the demand for round (or snail) steel bars is also increasing, but the round (or snail) steel bars cannot be used directly before they are put into production and construction. Or disc screw) steel bars are straightened and cut off. [0003] At present, there are many equipments capable of straightening and cutting steel bars, both at home and abroad, and some of them have automatic length-cutting equipment. However, the accuracy of these equipments is generally not high, especially the measuring wheel in the equipment. It is very easy to wear and tear. Once the measuring wheel is worn, the accuracy of the length will be greatly r...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many equipments capable of straightening and cutting steel bars, both at home and abroad, and some of them have automatic length-cutting equipment. However, the accuracy of these equipments is generally not high, especially the measuring wheel in the equipment. Very easy to wear, once the measuring wheel is worn, it will lead to a sharp drop in the accuracy of the length, and in severe cases, it will directly lead to the failure of the function of the length

[0004] In the existing steel bar straightening and cutting equipment with automatic sizing function on the market, the measuring wheels in it are made of steel wheels, and the measuring wheels are all rigidly fixed in the measuring mechanism. When the steel bars are in contact, wear is inevitable, and this wear cannot be solved at this stage; once the measuring wheel is worn, there will be slipping between the steel bar and the measuring wheel, and the slipping phenomenon will also lead to the accuracy of the sizing accuracy. The main reason for the decrease

[0005] In order to solve the wear and slipping phenomenon of the measuring wheel, the relevant technical personnel put forward the idea of ​​using a certain high hardness and high wear resistance material as the manufacturing material of the measuring wheel, but this material has not been found at this stage, even if this material is found , the manufacturing cost of the gauge wheel will also be very high, and in terms of cost, it does not conform to market rules
