To understand the performance of the slitting machine, we must
first have a certain depth of understanding of the slitter. There
are several aspects to measure the performance of the steel coil
slitting machine. Among them, the shear quality of the metal strip
is an important aspect of measuring the performance of the steel
coil slitting machine. The following detailed analysis of this
There are several factors that affect the shear quality of a metal
1. The upper and lower knife overlap
2. Side clearance
3. The uniformity of the hardness of metal coils.
The correct amount of overlap is to ensure that the metal sheet has
the best bite angle and the continuity of the shear. It is related
to the tensile strength, thickness, tension, shear force and tool
processing accuracy of the metal coil.
If the overlap amount is too large, the bite angle will be too
small, and the shear torque will be increased. If the overlap
amount is too small, the phenomenon of local shear shear will
continue to occur. Slitting shearing machine for metal strips will
inevitably appear partial knife jumping during the actual use.
Therefore, the maximum deflection of the cutter shaft and the
strength of the checking knife shaft must be set so as to avoid
affecting the correct shear overlap amount.
The machining accuracy of the tool is also an important factor
influencing the shear quality of the metal coil. It is related to
the efficient continuous cutting. If there is a gap between the
knife shaft and the hole in the knife, eccentricity will occur when
the knife moves. If the eccentricity is too large, intermittent
shearing will occur. However, with the continuous advancement of
technology, the current adjustment of the overlapping amount of the
slit strip slitting machine for metal strips has been digitally
automated, making it more accurate and convenient. For example, the
most representative brand in the industry, the Golden Goblet and
the Golden Goblet, has passed. In 18 years, he focused on the
research, development, and production of slitters for metal
slitting. It is quite mature in terms of technology. So that in the
industry there is a small celebrity.
The side gap of the steel coil slitting machine also determines the
quality of the edge of the stainless steel slit coil. The shear
zone and tear zone should be neat and the surface is smooth. The
general shear zone accounts for 20% of the thickness of the metal
coil. To 45%, the thicker the metal coil, the larger the shear
If the side clearance is too large, the metal coil will be
distorted, causing the shear area to become smaller, the tear area
to become larger, and the burrs on the edges to increase. Its size
is mainly related to the tensile strength and thickness of the
shear material, so it is generally required to be 3% to 8% of the
thickness of the metal coil.
The adjustment accuracy of the disc knife side gap of the metal coil slitting slitter
is mainly achieved through the processing precision of the disc
knife, composite rubber spacer and steel spacer, in simple terms,
thickness, flatness, parallelism, Surface finishes and other such
tolerances. In addition, the accumulated error of the group knife
will also affect the adjustment accuracy of the side clearance of
the disc knife. Therefore, the width accuracy of the cut metal coil
should be determined by the side clearance of the knife, and cannot
exceed twice the gap on the side of the knife.
The above is the depth analysis of the influence of the shear
quality of the metal coil on the performance of the steel coil
slitting line machine. Hopefully, it will help everyone.
