Pressure foot gasket worked as the seal ring to prevent the inner component from corrosion of dust and oil .
With this part , it can last the machine 's life and make the machine working more normally.
We could offer all kinds of pressure foot for other machines.
Form and material of pressure foot:
The main function of the pressure foot 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.
