Description
Technical field
The present invention relates to width notcher design field, more particularly, to a kind of tinuous production and width notcher.
Background technology
Width notcher is the key equipment of the tinuous production entrances such as cold continuous rolling line, smooth continuous annealing line, zinc-plated/tinned wire,
Main Function is to cut out crescent 012 in butt weld 011 both sides of steel 01, as shown in figure 1, on the one hand width notcher is excised
The edge weld defect of steel 01 and edge wedge angle produced by steel 01 stand out；Another aspect is the feed of circle shear and goes out knife
Space is provided.
Width notcher is mainly by assemblies such as sliding bottom, Shift cylinder, width notcher car body, cutting edge, mounting bracket, shearing oil cylinders
Composition, wherein, cutting edge includes the first cutting edge 02 and the second cutting edge 03, and as shown in Figures 2 and 3, shearing profile is curved, mounting bracket
It is mainly used in positioning, installation and the shears blades space adjustment of upper second cutting edge 02.At present, the shape of the first cutting edge 02 and the second cutting edge 03
Shape and structure are entirely different, the first cutting edge 02 generally semi arch pie, have the upper shear blade 021 of arc-shaped, as Fig. 2 institute
Show, its reference for assembling 022 is plane.Second cutting edge 03 is typically made up of 2-3 section, and Fig. 3 illustrates that the second of a kind of two sections of compositions cut
Sword 03.The reference for assembling 032 of the second cutting edge 03 is diagram inclined-plane or right-angle surface, the upper shear blade 021 and second of the first cutting edge 02
The down cut sword 031 of cutting edge 03 forms cutting mechanism.
Width notcher the first cutting edge 02 and second cutting edge 03 during work can occur abrasion it is therefore desirable to periodically to the
One cutting edge 02 and the second cutting edge 03 are changed or reconditioning, and as described in epimere, the structure of the first cutting edge 02 and the second cutting edge 03 is not
With therefore producer needs to carry out stock's stock to the first cutting edge 02 and the second cutting edge 03 respectively, and this can lead to inventory cost to increase.
In addition, in the cutting edge process segment, because of the architectural difference of the first cutting edge 02 and the second cutting edge 03, needing respectively to the first cutting edge 02 He
Second cutting edge 03 makes corresponding moulds of industrial equipment, in such cases, the inclined-plane for positioning or the gradient of right-angle surface, perpendicularity etc.
Form and position tolerance is relatively difficult to ensure card, and then leads to the machining accuracy to the first cutting edge 02 and the second cutting edge 03 relatively low, and equipment precision adjusts
Cycle stretch-out, the production cost of mechanic factory workers increases.It can be seen that, current width notcher exist maintenance, replacement cost higher and
The higher problem of manufacturing cost.How to solve this problem, particularly important.
Content of the invention
