Castor products castor seat treatment quality management
1, Contents and methods of incoming inspection:
1) Visual inspection for appearance: whether there are cracks,
bumps and rust spots.
2) Investigate the material of the workpiece: check the way of
grinding spark
3) If there is deformation, check the original deformation.
2, Contents and methods of first inspection, intermediate sampling
inspection and castor
inspection:
1. Hardness
1) Hardness inspection or sampling inspection shall be carried out
according to the drawing
requirements and process regulations. Calibrate the hardness tester
with a standard block and test
the hardness after confirmation. Quenched parts shall be inspected
with Rockwell hardness tester.
2) Before hardness inspection, the part surface shall be cleaned to
remove oxide scale,
decarburization layer and burr, and there shall be no obvious
machining marks on the surface. The
temperature of the tested part shall be subject to room
temperature, or slightly higher than room
temperature, but only if it can be grasped stably by hands.
3) The hardness testing position shall be determined according to
the process documents or by the
inspection and process personnel. The hardness of quenched parts
shall not be less than 1 place,
each place shall not be less than 3 points, and the non-uniformity
of general hardness value shall
be ≤ HRC 5 degrees.
2. Deformation
1) The flatness of thin plate parts shall be inspected with feeler
gauge on the inspection platform.
2) Both ends of shaft parts shall be supported by the center or
V-block, and their radial runout
shall be measured with a dial indicator. Small shaft parts can be
checked with a feeler gauge on the
platform.
3) For ring parts, use dial gauge, vernier caliper, plug gauge,
inner diameter dial gauge, thread plug
gauge, ring gauge, etc. to check the dimensions of the outer
circle, inner hole and thread of the parts.
4) Special testing tools for non-standard measured threads and
special parts.
3. Appearance: observe the surface with naked eyes for cracks,
burns, bumps, pits, corrosion, etc.
Important parts or parts prone to cracks shall be inspected by
means of kerosene immersion and
sand blasting.
4. Performance: testing equipment.
3, Inspection contents and methods of permanent deformation of
caster base plate:
1. Compress (stretch and twist) the finished caster base plate five
times to the height (length or
working limit torsion angle) under the working limit load, and
measure the height (or length and
angle) for the fourth and fifth times. If the value remains
unchanged, it is considered that there
is no permanent deformation.
2. The inspection of the load and dimensional tolerance, surface
shape and position tolerance
of the finished caster base plate shall be carried out after the
inspection of permanent deformation,
but the load and dimensional tolerance shall also be qualified
before the permanent deformation.
3. Fatigue test, impact test and simulation test of caster base
plate: Test of testing equipment.
4. The surface quality of caster base plate shall be measured
visually.
