A bendable steel bar cutting device for building construction

Abstract

The invention discloses a bendable steel bar cutting device for house construction, comprising a frame, a conveying mechanism, a cutting mechanism, a guiding and clamping mechanism and a bending mechanism arranged on the frame, and the conveying mechanism comprises a steel bar feeding material A conveying roller shaft assembly is arranged between the reinforcement inlet and the reinforcement outlet, the outlet is opposite to the cutting mechanism, and the cutting mechanism includes a cutting bottom plate and a retractable The cutting tool, the outlet of the cutting mechanism is opposite to the guide clamping mechanism, and the outlet of the guide clamping mechanism is opposite to the bending mechanism. And the cutting mechanism includes a cutting bottom plate and a cutting tool, and the cutting tool is provided with a slot for clamping the steel bar. The device of the invention realizes the integrated setting of steel bar cutting and bending, and can ensure the precision and reliability of cutting and bending.

Description

technical field [0001] The invention relates to an integrated machine for cutting and bending steel bars for house construction. Background technique [0002] A large number of steel bars need to be applied in the process of housing construction, and in order to facilitate loading, unloading and transportation, the steel bars are usually transported to the construction site in a straight state. However, in the construction site, it is often necessary to bend the steel bar to a certain angle or cut it to a certain length for use. In the existing use process, it is usually necessary to use a cutting device to first cut off the steel bar, and then use a steel bar bending machine to bend the steel bar with a certain length. As a result, the process is cumbersome and time-consuming, and the bending accuracy cannot be guaranteed during the cutting and bending process. [0003] In the Chinese patent CN207563634U, a steel bar bending and cutting integrated device is disclosed, and...

AI Technical Summary

Problems solved by technology

However, there are still many problems in the device in the above-mentioned patent: first, the reinforcing bar in the device cannot be fixed by only relying on two oppositely arranged supports. May bob up and down and jitter

It is very easy to get out of the fixed bracket when swinging. Once it is out of the way, the steel bar will not be able to bend or the bending angle and position will be wrong, resulting in unqualified products.

In this way, it is necessary to straighten the steel bar and then bend it again, which further delays the working hours.

Second, the device lacks axial positioning, so that the steel bar may slip in the axial direction during the bending process of the steel bar, resulting in bending errors and unqualified products

Third, the fixing bracket is extremely prone to wear due to excessive force during the bending process, resulting in reduced equipment life

[0006] However, the clamping mechanism for clamping steel bars provided in this patent cannot be integrated with the steel bar cutting machine. The steel bars must be cut and placed on the machine. Second, the clamping mechanism must be manually operated to clamp the steel bars. for reinforcement retention

Therefore, the efficiency is low, and the retaining mechanism is unreliable, and it is easy to swing up and down or left and right based on the fixed point
