The hydraulic heavy-duty material frame has become the most widely used discharge unwinding device because of its pneumatic pressing arm, oil pressure expansion and butterfly brake device.
Its maximum applicable material width is up to 2500mm, and the applicable material weight can reach 20T, which is far from being achieved by other types of material racks.
At present, the hydraulic press heavy material frame of 1300mm or more in the domestic stamping market has greatly enhanced the strength of the fuselage compared with the small and medium-sized hydraulic heavy-duty material frame.
However, the structure is exactly the same, although it can be used, but the customer has great deficiencies in the actual use. The main surface is when the width of the material roll is too large, the end of the oil pressure heavy material frame will sink, abnormal. Swinging the scene. The emergence of this phenomenon will bring two very serious hazards:
1. When the shearing and stamping production line is running, the sinking of the end will cause the roll to slip, which directly affects the centering of the material and causes the material roll to appear bulk material, which affects the use of production.
2. The end sinking is very easy to cause the three shafts of the hydraulic heavy-duty material frame reducer to be bent or broken, resulting in great safety accidents and serious consequences of online scrapping.
In order to fundamentally solve such deficiencies, Ruihui Machinery has added a spindle end support device when designing and manufacturing hydraulic heavy-duty material racks with widths of 1300mm and above.
It can provide good and reliable support to the end of the spindle, and eliminates the fluctuation and sinking of the end of the spindle, which fundamentally solves the problem of roll slip, centering change, strain reduction reducer, etc. during unwinding, truly ensuring The reliable operation of the material rack when unwinding large rolls.
