Operation failure of automatic numerical control hydraulic steel bar straightening and cutting machine

Automatic steel bar straightening and cutting machine is a new type of automatic straightening machine, which is developed to meet the requirements of the new standard to improve the strength of steel bars and ensure the straightening of three and four grades of steel bars. The straightening system uses two ways to straighten to ensure the quality of steel bar straightening, and adopts the technology of cutting instantaneous stop to reduce the impact on the cutter and prevent the straightening steel bar from being hit and bent.

The automatic steel bar straightening and cutting machine has the functions of automatic feeding, straightening, measuring, cutting and collecting. It is an ideal automatic equipment for processing cold-rolled and hot-rolled ribbed steel bars, and is widely used in steel processing enterprises

(1) (2) the hydraulic system is controlled by cartridge valve or slide valve system and operated by buttons in a centralized way; (3) its pressure, speed and stroke can be adjusted according to the process requirements, and can complete the pressing and shaping process. Shearing machine is a kind of machine tool. It is driven by hydraulic pressure. It has reliable safety performance and convenient operation. The cutting edge length of shears: 400mm, 600mm, 700mm, 800mm, 1000mm, 1200mm; the shear force ranges from 63T to 400t, which is suitable for users with different sizes and requirements. Installation does not need foot screw, and diesel engine can be used for power supply where there is no power supply. The shears are suitable for cold cutting and flanging of various shapes of steel and metal materials, as well as the pressing and forming of powder products, plastics, glass fiber reinforced plastics, insulating materials and rubber.

Technical features:

A. High efficiency: the steel bar straightening speed is stepless, and the theoretical design can reach 160m / min;

B. High precision: the outstanding feature of this machine is high precision, the cutting length error is less than ± 1 mm;

C. After straightening, the small ribs were straightened by torsion;

D. The hydraulic system is used as the driving force and the accumulator design is adopted for the cutting. The cutting force is large, the cutting action is fast, and the rib damage on the steel surface is small;
