HYJ-800 Motor Drive Higher Speed I H Beam Straightening Machine

Importance: Of all types of H Beam Flange Straightening Machine, HYJ800 model motor drive has the longest history in application, and one of the largest selling volume.

1. Application Features of HYJ-800 High Speed H Beam Straightening Machine:

1) Straightening power source in HYJ-800 model machine: 

Design sketch: (Fig.1)

Actual photo on H Beam flange straightening action driving motors of Wuxi JACK HYJ800 model machine: (Fig.2)

Straightening Drive Source: HYJ-800 and HYJ-40 models adopt with A.C. motor as source of its straightening driving force. This is the most distinguished difference with YTJ series hydraulic drive, and hence its product name of "Motor drive" got from;

2) Straightening Capacity: The HYJ-800 is kindred product of HYJ-40. In terms of straightening capability, HYJ-800 model has the same max. straightening thickness as HYJ-40 model: Up to 40mm flange thickness:

3) Difference between HYJ-800 and HYJ-40 Model H Beam Straighten Machine:

The difference between HYJ-800 and HYJ-40 models lies in its higher straightening speed of 17m/min., compared with 9m/min. in HYJ-40 model;

4) So, why develop HYJ-40 I Beam Straightening Machine on the basis of HYJ-800?

a) As we discussed before, HYJ-40 is more applicable to be used in automatic H Beam Production Line than HYJ-800, in view of compatible working tempo with the other H Beam production equipment, including H Beam Assembly Machine (Around 1200mm ~ 3000mm/min.) and H Beam Submerged Arc Welding Machine (Around 400mm ~ 1000mm/min.);

b) This is the reason why recent years sees HYJ-40 model gradually replaces HYJ-800 model in automatic H Beam Production Line;

b) On the other hand, as the longest history and the ever largest selling volume of H Beam Straighten Machine, HYJ-800 still takes prominent position in application of its product family, benefiting from its quickest straightening speed.

2. Application Technical Features of HYJ-800 High Speed I Beam Straightening Machine:

1) Empirical Data: One of matters needing attention is, there exist rule of thumb on relationship between flange thickness and flange width that can be straightened as below:

(For Q235, tensile strength 370~ 510MPa)

Table on Relationship of H Beam Flange Thickness with respect to Width for effective straightening:

2) Transmission Unit of Wuxi JACK HYJ-800 model machine: (Fig.4)

Main transmission system is adopted with 22kW motor and driven with cycloidal gear speed reducer, which features in high transmission efficiency and rapid straightening speed;

3) Working Elements: All the straightening rollers are made of quality steel, and have gone through advanced heat treatment, insuring long term stability and usage without defects such as crack, etc.

b) Besides, all the parts and components of the HYJ series I H Beam Straightening Machine are reinforced. This makes the machine a sturdy one;

4) Easy operation on Wuxi JACK H Beam Straightening Machine: (Fig.6)

Besides operating panel on control board, Wuxi JACK HYJ-800 model machine is equipped with operating pendant close to straightening area;

5) Straightening Principle: HYJ series and YTJ series machine share the same straightening principle. Please check product section of “Vertical Position YTJ40 Hydraulic model Machine”.
