Description

Filter stick framework

Technical Field

The utility model relates to a filter stick framework.

Background

The grinding oil filtering and recycling field mostly uses a rod-shaped filter at present, and the filter can effectively filter and recycle the grinding oil. The rod filter mainly comprises a filter stick framework, a spring, a bolt, filter paper and other components.

The filter stick framework is the most complex part for manufacturing the rod-shaped filter, referring to fig. 1 and fig. 2, the prior art is mainly formed by combining and welding two semicircular frameworks 1 and two independent inserting pieces 2, and each semicircular framework 1 is provided with a hole. The current mainstream production implementation method is as follows: firstly, cutting a porous carbon steel plate into pieces by laser, then pressing the pieces into a semicircular framework 1 by a forming die, or cutting the plate by the laser of a punching plate, and then pressing the plate into the semicircular framework 1 by the forming die; then the two semicircular frameworks 1 are welded into a whole through the lining pipe 3. The U-shaped inserting piece 2 is also pressed into a semicircle through a forming mould, and is welded with the semicircular framework 1 through the lining pipe 3. The existing production implementation method has the following problems:

1. when the pore plate is pressed and formed by a mould, because the metal plate has extensibility and internal stress, a true semicircle is difficult to achieve, so that the forming is not accurate enough, the section of the welded two semicircular frameworks is not a perfect circle, and the filter paper is difficult to penetrate, so that the production efficiency is low;

2. when the two semicircular frameworks are welded, one welding process is added, and meanwhile, welding of a plurality of lining pipes is added, so that not only are welding points increased, but also the investment cost of the lining pipes is increased;

3, the U-shaped inserting piece needs to be welded with the circular tube through the lining tube, so that more welding points are needed, and the concentricity of the U-shaped inserting piece and the circular tube is difficult to maintain, so that the product quality is seriously influenced;

4. all welding spots are polished, one more process flow is needed, and the production cost is increased; the complete assembly framework after polishing needs hot galvanizing, and a process flow is added, so that the production cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a filter stick framework which is formed by cutting and processing a whole metal tube, avoids the welding process, and has the advantages of reasonable structure, simple process, high strength and low cost.

In order to solve the technical problem, the utility model provides a filter stick framework, which comprises a metal round pipe body which is vertically arranged, wherein the upper part of the outer wall of the metal round pipe body is provided with two notches which are oppositely arranged along the radial direction of the metal round pipe body and penetrate through the wall thickness direction of the metal round pipe body, the upper end of each notch extends to the upper end of the metal round pipe body, the rest part of the upper part of the metal round pipe body, corresponding to the notches, is provided with two arc-shaped inserting pieces which are oppositely arranged, the arc length of each arc-shaped inserting piece accounts for one fourth of the perimeter of the metal round pipe body, the upper part of each inserting piece is provided with an inserting piece hole at the position corresponding to the arc center, the inserting piece holes on the two inserting pieces are coaxially arranged, the axis of each inserting piece is intersected with the axis of the metal round pipe body, the middle part and the lower part of the metal round pipe body are provided with a plurality of strip-shaped through grooves which are arranged in a row around the circumference of the metal round pipe body, the lower end of the metal round pipe body is provided with two pipe holes which are oppositely arranged, the two pipe holes are coaxially arranged, and the axes of the two pipe holes are intersected with the axis of the metal round pipe body.

The utility model has the advantages that: the utility model is formed by cutting and processing a whole metal round pipe, the arc-shaped inserting piece and the metal round pipe body do not need to be welded, the arc-shaped inserting piece and the metal round pipe body are of an integrated seamless structure, the arc-shaped inserting piece and the metal round pipe body can be conveniently welded with other parts, the concentricity is high during installation, and the welding process in production is reduced, so that the processing technology is simple, the strength is increased, and the cost is reduced.
