Description

Windscreen wiper crank and material structure of arranging of windscreen wiper crank that high-efficient utilized
Technical Field
The utility model relates to a windscreen wiper crank and windscreen wiper articulate that high-efficient utilized arrange material structure.
Background
The existing wiper crank structure is shown in figure 1, the shapes of a main stress end and a non-main stress end are close to each other, and arc edges 11 are arranged, when the wiper crank structure is punched, formed and discharged, a large amount of leftover bits and pieces are formed by adopting plates in a punching mode, the material utilization rate is 60-70%, and when the wiper crank structure is punched, the whole periphery is sheared, so that a punch press with larger tonnage is needed relatively.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough according to above, provide a windscreen wiper crank of high-efficient utilization.
The technical scheme of the utility model is that:
the utility model provides a windscreen wiper crank that high efficiency was utilized, includes the windscreen wiper crank, the windscreen wiper crank is provided with main atress end and non-main atress end, is provided with main atress hole in the main atress end, and non-main atress end is provided with non-main atress hole, and characterized by, main atress end are provided with the circular arc chimb, and non-main atress end is provided with the circular arc concave edge, and the circular arc chimb coincide with the circular arc concave edge.
It needs to be explained that, its atress intensity of main atress end is obviously higher than non-main atress end, as long as can satisfy the intensity requirement at the thinnest edge in main atress hole, other parts also must satisfy the intensity requirement, the utility model discloses thinnest edge is the circular arc chimb, its width satisfy intensity can, and the circular arc concave edge is located non-main atress end can allow the intensity difference a bit, and the most important can provide convenience for arranging the material structure.
Preferably, the arc convex edge and the main stress hole are concentrically arranged, the structure forms a structure which saves materials most, and the arc convex edge is uniformly stressed.
Preferably, the arc convex edge corresponds to an arc angle of 120 degrees.
Preferably, the other positions around the main force-bearing hole, the shortest part of the radial distances thereof, are the arc convex edge.
Preferably, the main stress end is provided with two symmetrical main stress right angles, and one right-angle side of each main stress right angle is connected with the arc convex edge; the non-stressed end is provided with two symmetrical non-stressed right angles, and one right-angle side of each non-stressed right angle is connected with the arc concave side.
The utility model also discloses a windscreen wiper articulate arranges material structure, include the windscreen wiper crank that high efficiency utilized, it is provided with a plurality ofly, a style of calligraphy is arranged, wherein a articulate main stress end of windscreen wiper links up with the articulate non-main stress end of another windscreen wiper and arranges the material, forms single windscreen wiper crank through the punch press blanking.
Obviously, the line that this row material structure needs to be tailor is very short, therefore, the mould is simpler, and required tonnage also can obviously reduce.
The utility model discloses all the other do not have any waste material except two holes in the middle of, material utilization reaches more than 95%, and is die-cut only to have a section, and die-cut power is only original 10%, just can accomplish die-cut with the punch press of very little tonnage.
The utility model discloses can save material 25% ~30%, save blanking power 80~ 90%.
The utility model discloses have material saving, with low costs, intensity assurance, save material, extension mould life's beneficial effect.

Detailed Description
The present invention will now be further described with reference to the accompanying drawings:
as shown in the figure, a windscreen wiper crank that high efficiency was utilized, including windscreen wiper crank 2, windscreen wiper crank 2 is provided with main atress end and non-main atress end, is provided with main atress hole 22 in the main atress end, and non-main atress end is provided with non-main atress hole 23, and characterized by, main atress end is provided with circular arc chimb 21, and non-main atress end is provided with circular arc concave edge 24, and circular arc chimb 21 coincide with circular arc concave edge 24.
The circular arc convex edge 21 is arranged concentrically with the main force receiving hole 22.
The arc flange 21 corresponds to an arc angle of 120 degrees.
The shortest part of the radial distances around the main force-receiving hole 22 is the arc convex edge 21.
The main stress end is provided with two symmetrical main stress right angles 26, and one right-angle side of each main stress right angle 26 is connected with the arc convex edge 21; the non-stressed end is provided with two symmetrical non-stressed right angles 25, and one right-angle side of each non-stressed right angle 25 is connected with the arc concave side 24.
The utility model provides a windscreen wiper crank arranges material structure, includes the windscreen wiper crank that the high efficiency utilized, and it is provided with a plurality ofly, and a style of calligraphy is arranged, and wherein the main stress end of a windscreen wiper crank 2 links up with the non-main stress end of another windscreen wiper crank 2 and arranges the material, forms single windscreen wiper crank 2 through the punch press blanking.
