Form and material of pressure foot:
The main function of the front cover is to compact the workpiece
system. Through its slotted ventilation structure, it provides air
supplement for the vacuum system, forms a better convection system,
and has a larger buffer effect. Different brands of mechanical
drilling design manufacturers based on different considerations,
the material of the pressure foot is metal materials and non-metal
materials. Metal materials are mainly stainless steel (usually
SUS304) and brass materials (C3604BD, equivalent to HPb59-1).
Non-metal materials are mainly PA66, PA6, POM and PU. The main
considerations for the use of metal materials are relatively high
hardness, wear resistance, and long service life (normally 8-10
months can be used); the disadvantage is that the buffer effect is
not obvious, and it has not stabilized for a long time. The use of
industrial rubber materials (PU, PA6 PA66) mainly considers good
vibration absorption characteristics. For the impact process, it
can achieve a significant vibration absorption effect, and the
amplitude can be reduced in a short time. The disadvantage is that
the hardness is relatively low and it is not resistant to wear.
Life is short, usually around a week. Using ABAQUS software
simulation, adjust the presser foot material, analyze with 100N
presser foot force and 10kpa vacuum void, and analyze the use of
rigid presser foot and PU presser foot. As shown in picture 1, the
upper and lower curves respectively indicate the numerical
displacement curve of the "drill point" under the steel presser
foot and the PU presser foot. It can be seen that the presser foot
impacts with the presser foot force and oscillates, and the
oscillation attenuates regularly within 0.06S; however, the PU
presser foot has a significant vibration absorption effect. After
the oscillation is initiated, the "drill down point" quickly
stabilizes. Stability is reached at about 0.001S. Based on the good
vibration absorption performance of industrial rubber, most
drilling machine manufacturers currently use industrial rubber
pressure feet.
PCB numerical control drilling machine as an important equipment in
printed circuit board processing, its processing quality has a
great impact on the performance of electronic products. Its suck
The combined structure of chip cover and pressure foot is one of
the main factors affecting the quality of hole processing.
Excellent design and combination of the combined structure of the
suction hood and the pressure foot
Reasonable pressure foot pressure and vacuum suction negative
pressure settings are the key to ensure high quality drilling of
printed circuit boards. Under most operating conditions, the design
of the gap between the chip suction hood and the spindle as small
as possible, the tangent of the exit center vector line and the
outer diameter of the dust spiral line, and the lightest possible
mass design, combined with industrial rubber with excellent
vibration absorption performance The pressure foot, the pressure
foot pressure is set to about 100 N and the vacuum vacuum negative
pressure is about 10 kPa, which can achieve efficient dust
extraction and high-quality drilling of the dust cover.
