Processing technology for forming micro hole in relatively thick sheet material

Abstract

The invention relates to a processing method of a sheet material, in particular to a processing method for forming a micro hole in a relatively thick sheet material. The processing method comprises the following steps of: step 1. cutting the sheet material; step 2. forming notches; step 3. cutting chamfers; and step 4. punching. The processing method has the beneficial effects that the micro holecan be formed in the relatively thick sheet material according to the processing method for forming the micro hole in the relatively thick sheet material; and reinforcing ribs which are integrated with the sheet material are formed in the notches on the sheet material, so that the sheet material has relatively firm structure and relatively thick wall, and the manufacturing of workpieces bearing high pressure and realizing high-precision cooperation can be satisfied.

Description

technical field [0001] The invention relates to a processing method of a plate, in particular to a processing technology for opening tiny holes in a relatively thick plate. Background technique [0002] Limited by the scope of drilling and the requirements of working conditions, it is difficult to realize the traditional method of opening tiny holes in thicker plates. In actual use, such as the filter screen processing technology of solid-liquid separation, the filter screen should deal with the working conditions of high pressure and fine particle materials. , the filter needs a thicker plate, and the filter hole needs to meet the requirements of small micropores, so the traditional processing method is to directly open holes on a thinner plate or to form a filter at a high cost on a thicker plate, and then Welding reinforcing ribs on the filter screen plays a supporting role and improves the mechanical strength of the filter screen. If the reinforcement ribs are too dense,...

[0002] Limited by the scope of drilling and the requirements of working conditions, it is difficult to realize the traditional method of opening tiny holes in thicker plates. In actual use, such as the filter screen processing technology of solid-liquid separation, the filter screen should deal with the working conditions of high pressure and fine particle materials. , the filter needs a thicker plate, and the filter hole needs to meet the requirements of small micropores, so the traditional processing method is to directly open holes on a thinner plate or to form a filter at a high cost on a thicker plate, and then Welding reinforcing ribs on the filter screen plays a supporting role and improves the mechanical strength of the filter screen. If the reinforcement ribs are too dense, the filter holes of the filter screen will be reduced. In order to ensure the number of filter holes, the number of reinforcement ribs must be reduced. The plate body between the ribs is deformed under high pressure, and there is a gap between the pressurized body and the filter screen, which makes the material stay and affects the dehydration effect;

[0003] For workpieces with limited openings, it is difficult to open small holes on thicker plates, such as screw extrusion dehydrators. The disadvantage of traditional processing methods is that the working pressure is relatively high, and the solid-liquid separator needs more Thick filter barrel, under high-strength working conditions, the filter will be deformed due to extrusion, which will affect the dehydration effect and even cause machine damage

The reinforcement ribs added later cannot be integrally formed with the workpiece, the cylinder is not strong enough, and there will be a small gap between the reinforcement ribs and the filter screen, which cannot achieve the effect of reinforcement, and there is room for deformation of the thin screen under high pressure
