Abstract

The invention is the sweep brush used by motor sweeper and its preparation method. The brush strips (4) and inner ring parts (3) are all polypropylene materials. The (4) are pp wires and the (3) are pp packing belts. The inner end of (4) melts and bonds to the outside of (3). The inner ends of (3) and (4) are fixed and linked by the extrusion of metals. The combination of (4), (3) and metals is more firmly. The preparation method is more simple and easier to operation. The arrangement of the brush strips is more orderly and uniform.

Description

A kind of sweep brush for road sweeper and preparation technology thereof

Technical field the present invention relates to a kind of sweep brush and preparation method thereof, specifically, is a kind of matching used sweep brush of road cleaner and preparation method thereof that is.

Background technology is existing to be the matching used sweep brush of road cleaner, owing to the following shortcoming of reason ubiquity of structure, material and manufacture craft aspect, first, the brush bar not ideal enough in conjunction with firmness, easily come off in the use.The second, complicated process of preparation, working (machining) efficiency is low, and brush bar regularity, the uniformity are not enough.

Summary of the invention the objective of the invention is to, and a kind of sweep brush for road sweeper and preparation technology thereof are provided, in order to overcome the defective of above-mentioned existing procucts and processing method.Technical problem to be solved is, makes to combine more firmly between brush bar and inner ring spare and the metalwork, and makes that the preparation method is simple more, easy operating, and the brush bar is arranged neat more, even.

The technical solution adopted for the present invention to solve the technical problems is as follows:

A kind of sweep brush for road sweeper comprises brush bar and the inner ring spare that is used to be connected brush bar the inner, and it is characterized in that: brush bar and inner ring spare are polypropylene material, and wherein brushing bar is the PP silk, and inner ring spare is a PP matter strap; The inner fusing of brush bar is bonded in the lateral surface of inner ring spare; Inner ring spare is fixedlyed connected by extrustion of metals with brush bar inner end.

Also be coated with adhesive between brush bar inner end and the metalwork.

A kind of preparation technology of sweep brush for road sweeper is characterized in that: it may further comprise the steps:

1), get 1.0-1.4 millimeters thick black iron plates, punching press all-in-one-piece metalwork, this metalwork middle part is a straight tube-like, two ends are continuous cambered surface valgoid;

2), one section PP matter strap of intercepting as inner ring spare raw material, brush bar the inner is welded on any one side as lateral surface of inner ring spare equably, the described Plastic Welding that is welded as is about to brush the inner high temperature melting of bar and is bonded on the lateral surface of inner ring spare;

3), with the 2nd) step goods bending surrounds the 1st) middle part of step goods, inner ring spare two-end-point butt joint medial surface is fitted in the metalwork middle part, enters the 4th) the step operation;

4), from the metalwork two ends application of force, adopt the punch forming method with metalwork inwardly extruding make its two ends compress brush bar the inner.

The 3rd) in the step, at the inner adhesive coating of brush bar.

Compare with existing product and technology, good effect of the present invention is:

(1), PP silk the inner is welded on the inner ring spare equably, inner bonding with metalwork of fixing and PP silk by the extruding of metalwork again, three kinds of fixed forms have guaranteed the strong bonded of brush bar.On the other hand, the operation of welding PP silk is to carry out on vertical bar shape strap, again strap is bent into circle after welding, and has made full use of the bending and molding performance of strap, and is easy to operate, high efficiency.The more important thing is, can arrange equably to connect the PP silk, the brush bar of finished product sweep brush is distributed neatly evenly, this point prior art is difficult to accomplish, because existing way is to connect the brush bar again after inner ring spare is injection molded into circle.The third aspect selects brush bar and inner ring spare to be polypropylene material, has given full play to the advantage of the identical moldable welding of PP storeroom.

(2), adopt one whole iron plate to strike out metalwork, metalwork is structure as a whole, and does not have weld seam, and is easy to process, product is attractive in appearance.

(3), the extension of selected iron plate model and thickness and punching performance just in time are suitable for this process.

Description of drawings Fig. 1 is a structural representation of the present invention.

Fig. 2 is the structural representation of metalwork among the present invention.

Fig. 3 is 2 A-A sectional view.

The specific embodiment is as Fig. 1--and shown in 3, sweep brush of the present invention comprises brush bar 4 and the inner ring spare 3 that is used to be connected brush bar 4 the inners.Brush bar 4 and inner ring spare 3 are polypropylene material, wherein brush bar 4 and are the PP silk, and inner ring spare 3 is a PP matter strap.The 4 inner fusings of brush bar are bonded in the lateral surface of inner ring spare 3; Inner ring spare 3 and brush bar 4 inner ends are formed by connecting by extrustion of metals.

Also brush between brush bar 4 inner ends and the metalwork adhesive is arranged.

The preparation technology's of this sweep brush example may further comprise the steps:

1), get 1.2 millimeters thick black iron plates, model is the Q195 type, punching press all-in-one-piece metalwork, this metalwork middle part 1 is a straight tube-like, two ends 2 continuous cambered surface valgoids;

2), one section PP matter strap of intercepting as inner ring spare 3 raw materials, 8 millimeters of width, 2 millimeters of thickness, with plastic welding gun PP silk the inner is welded on equably on any one side of strap as lateral surface, the described Plastic Welding that is welded as is about to the inner high temperature melting of PP silk and is bonded on the lateral surface of strap;

3), with the 2nd) step goods bending surrounds the 1st) middle part of step goods, strap two-end-point butt joint medial surface relies on bonding adhesive to be fitted in metalwork middle part 1 straight length, and enters the 4th at the inner adhesive coating of PP silk) the step operation;

4), from the metalwork two ends application of force, adopt the punch forming method with metalwork inwardly extruding make its two ends compress PP silk the inner.

For this sweep brush is connected with installation shaft, also to a rivet be installed on metalwork, an end of rivet is fixed on the middle part of metalwork, and the other end is deep in the cavity of metalwork middle part.
