NJC Cropping shear & Cutting shear and Start stop type flying shear

Product Overview

Description

Flying shear, which belongs to hot shear, is a kind of flying shears. It is mainly used in the steel bar, wire and profile production line, and the cutting head, cutting tail, accident breaking, and double rule section of the rolling piece.

Jinxin transmission design and manufacturing flying shear can meet the requirements of modern rolling process for large rolling section and high rolling speed.At the same time, we can carry out non-standard customization according to the actual needs of customers, and meet the requirements of customers' personalized rolling process, such as the flying shear of channel steel, Angle steel and other sections.

 

Flying shear classification and main parameters.

According to the layout and shear specification of the steel mill, the flying shear is divided into 1# flying shear, 2# flying shear and 3# flying scissors.

·1# flying shear is located in front of the middle rolling mill, normally located in front of the gearbox of 7H rolling mill.

·2# flying shear is located in front of the gear box of 13H rolling mill.

·3# flying shear in the finishing mill group, usually after 18 racks.

What are your advantages in choosing jinxin transmission?

 

1. Strong technical background of non-standard speed reducer.

 

·75 national patents for non-standard speed reducers;

·9 high and new certification of non-standard speed reducer;

· jiangsu province gear box engineering technology r&d center, jiangsu province key research and development organization.

 

2, with more than 300 ten thousand yuan to purchase the ProE three dimensional optimization design and calculation software, select the best transmission scheme, the design parameters of selected in accordance with the truth, good mechanical properties and the extreme load, extreme temperature difference remained stable material, practical and concise structure, etc.;

3. Adopt advanced reduction machine processing equipment, such as Germany, Japan, the United States and Austria, and the product quality reaches the level of the international top speed reducer, far exceeding the national standard;

4. It can meet the requirements of the actual working conditions, and has the characteristics of compact structure, high load resistance, frequent impact, stable operation and continuous operation.

5. The box structure is designed according to the overload design, and there is sufficient safety factor to withstand the impact load in the case of the device's stop and accident.

6. Components and assembly.

 

Square root fasteners, connecting parts firm, not loose;

The rotating parts of the square root rotate flexibly, noiseless, vibration-free and non-jamming.

The lubricating system of the square root of the lubrication system with proper type and sufficient amount of lubrication is good, without oil leakage;

There is sufficient observation hole in the meshing part of the square root gear to observe the operation of the reducer.

7. Test

 

Before leaving the factory, each mill reducer must be tested.At the rated speed, the load test is carried out, the bearing temperature is normal, the sound of gear meshing is even, and there is no leakage in each combination surface.
