Description

Integrative frame of air cleaner

Technical Field

The utility model relates to an air cleaner product component especially relates to air cleaner frame.

Background

The air filter mainly comprises a filter element and a frame for supporting the filter element, wherein the importance of the frame structure and the quality of the frame structure on the service performance of the air filter is not inferior to that of the filter element, on one hand, the frame structure determines the attractive appearance of the product, and more importantly, the frame structure has high strength, keeps good flatness and interface fitting degree, and is an important judgment standard for the product quality of the air filter.

The existing frame is mainly made of aluminum alloy sections and assembled into a frame through cutting, punching and riveting, or the frame is assembled by plastic injection molding materials, or the frame is assembled by processing, manufacturing and molding galvanized plates. The galvanized sheet material is low in purchase cost and becomes the choice of most of filtering products. However, the manufacturing process of the galvanized sheet frame is more complicated: the frame is formed by bending or rolling into a U-shaped groove, then cutting, chamfering, bending the inserting sheet and punching, finally riveting and fixing four corners to assemble the frame, the whole process is provided with a plurality of types of equipment, the number of operators can reach 6-8, the manufacturing cost advantage is extruded, the production efficiency is low, the component quality is difficult to guarantee, in addition, the integrity, the flatness and the interface integrating degree of the frame can be influenced by a split assembly structure, the material quality, the processing quality, the split assembly and the assembly operation thereof, and the product quality is poor and unstable.

Disclosure of Invention

The invention aims to solve the technical problems of low manufacturing efficiency, unstable product quality, integrity, flatness and poor fitting degree of a galvanized plate frame of an air filter, and provides an integrated frame of the air filter by replacing the existing split assembly structure with an integrated structure.

The application provides an integrative frame technical scheme of air cleaner, its main technical content is: the utility model provides an integrative frame of air cleaner, this frame is galvanized sheet cell body section bar in the square bend of diagonal cut right angle until the closed fixed connection's of head and tail end square frame body, the diagonal cut be that the projection is unanimous on the both sides of groove, make in the bending cut edge and bump shoulder to right angled isosceles incision, cell body section bar both ends all are equipped with and are used for closed grafting complex diagonal angle half angle incision, cell body section bar one end is equipped with upright in the inserted sheet of tank bottom, is equipped with the rivet hole that the position corresponds on the inserted sheet and the closed back other end tank bottom.

The technical scheme of the air filter integrated frame disclosed by the patent application is formed by bending an integrated galvanized plate groove body section bar to two ends for closing and riveting, and has the technical advantages of strong integrity, high flatness and good interface fit; in addition, the galvanized sheet groove body section can be continuously processed and manufactured by one set of production line equipment in multiple processes, the production efficiency is high, fewer production and preparation personnel are needed, and the cost is lower.

Detailed Description

The air filter integrated frame disclosed by the application is a frame body 2 formed by bending a galvanized sheet groove body section bar 1 in a diagonal cut 3 at right angles to be fixedly connected in a closed end-to-end mode as shown in figure 1.

The diagonal cuts 3 on the groove body section bar 1 are isosceles cuts which have consistent projections on the two groove sides 12 and enable the two cut edges to be in collision with shoulders to be bent at right angles in bending, included angles between the isosceles cut edges 31 of the cuts and the surface where the groove bottom 10 is located are the same, and the top angle alpha of the cuts is a right angle or close to the right angle, and in the embodiment, the top angle alpha of the cuts is 89.2 degrees; rectangular notches 14 are formed in the top corners of the notches, the notches 14 are formed in the bottom lines 13 of the inner corners of the groove body section bar 1, and the notches 14 are process openings for accommodating the bending corners of the galvanized sheet to be subjected to plastic deformation.

The two ends of the groove body section bar 1 are provided with diagonal half-angle notches 4 which are mutually inserted into a closed state, the diagonal half-angle notches 4 are notches with consistent projections on the two groove sides, and the notch angles of the two pairs of diagonal half-angle notches 4 at the two ends are mutually surplus. The slot body section bar 1 one end is equipped with the inserted sheet 11 of standing vertically in tank bottom 10, be equipped with the rivet hole that the position corresponds when both ends are closed on the inserted sheet 11 with the tank bottom 10 of the other end, as shown in fig. 3, 1 closed angle 7 departments of slot body section bar head and the tail, the inserted sheet 11 laminating is in the tank bottom 10 inner face of the other end, when 11 base angle limits of inserted sheet coincide with closed end port, inserted sheet rivet hole 5 and closed end tank bottom rivet hole 6 correspond and communicate with each other, constitute the square frame body 2 of frame through wearing to establish 8 rivets.

In order to improve the supporting strength of the tank body section bar 1, the edge of the tank edge 12 is rolled inwards to form a covered edge 9.

The tank body section 1 is formed by rolling a galvanized sheet strip through edge wrapping, punching diagonal cuts 3, inserting sheets 11, diagonal half-angle cuts 4, inserting sheet rivet holes 5, closed end tank bottom rivet holes 6 and rolling into a tank shape, and finally cutting.
