Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Such as Figure 1 to Figure 4 Shown, a kind of steel bar straightening method of the present invention, the method step is as follows:

[0030] S1: Send the steel bars to be treated into the heating furnace for preheating treatment, and the steel bars after preheating treatment are easy to straighten;

[0031] S2: Send the steel bars preheated in S1 to the straightening and cutting machine for straightening and derusting;

[0032] S3: In S2, the side of the fixed cutting device of the straightening and cutting machine is fixedly installed with a liquid spray head. Nitrate solution;

[0033] S4: After the steel bar in S3 is derusted, turn on the liquid spray head in S2 to spray the steel bar to prevent rust on the steel bar;

[0034] S5:...

Abstract

The invention belongs to the technical field of steel bar processing, and specifically relates to a method for straightening steel bars. The straightening and cutting machine used in the method includes a frame, and the frame is sequentially provided with a straightening device, a conveyor belt, and a fixed cutting device. and a limit stopper; a derusting module is provided between the conveyor belt and the fixed cutting device, and the derusting module includes a swivel, a scissor mechanism and a centrifugal ball; the swivel is sleeved on the steel bar, and the swivel The ring is provided with teeth, and one side of the swivel is provided with a rotating gear; the scissors mechanism is composed of a set of connecting rod ends hinged in the middle, and the side of the scissors mechanism close to the steel bar is provided with a steel wire belt; A vibrating spring is connected between the ends of adjacent connecting rods on both sides of the swivel; a centrifugal ball is connected to the vibrating spring through an elastic rope; The solution is used to brush the surface of the steel bar to prevent rust, thereby improving the surface quality of the steel bar and the working performance of the steel bar.

Description

technical field [0001] The invention belongs to the technical field of steel bar processing, in particular to a steel bar straightening method. Background technique [0002] With the gradual improvement of the economic level and the diversified development of architectural forms, steel bars are used as the main steel material for construction, and steel bars must be used in various engineering projects with complex functions and various shapes. However, when the steel bars are delivered to the construction site, their shapes are also different, and the steel bars are often corroded when placed in the open air, which will reduce the gripping force of the steel bars and concrete, and affect the performance of the two working together; accordingly, the present invention proposes a steel bar Straightening method. [0003] There are also some technical solutions for steel bar pretreatment in the prior art. For example, a Chinese patent with application number 2017205981258 discl...
