Description
Technical Field
The utility model relates to an automobile brake technical field, especially a steel backing of protruding thorn of commercial car strengthening rib type.
Background
The steel backing is a part of the brake pad and mainly plays a role in fixing. At present, the bonding technology in the industry is to increase the bonding strength in an auxiliary way of punching a plurality of process holes on a steel backing, and too many process holes are easy to ensure the precision of the backing plate, cause distortion and deformation and influence the flatness; the back plate and the friction material are easy to have insufficient bonding strength due to few process holes, and the potential safety hazard of the automobile braking performance can be caused by insufficient bonding strength and friction force.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, a steel backing of the protruding thorn of commercial car strengthening rib type is provided.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is: the utility model provides a steel backing of protruding thorn of commercial car strengthening rib type, includes the steel backing, and the last equipartition of steel backing has a plurality of protruding thorn, and protruding thorn distributes into a plurality of rows with the direction that is on a parallel with rolling direction A on the steel backing, every the root position department that protruding thorn and steel backing are connected is equipped with the strengthening rib.
Among the above-mentioned technical scheme, a plurality of protruding thorn is with the direction opposite distribution of being on a parallel with rolling direction A on the steel backing to become a plurality of rows, and the direction of protruding thorn is the same on same line, and the direction of protruding thorn is opposite in two adjacent lines.
In the technical scheme, a certain inclination angle theta is formed between each convex thorn and the plane of the back plate, and the inclination angle theta is not more than 90 degrees.
Among the above-mentioned technical scheme, the strengthening rib is long triangle-shaped structure, and the thickness dimension D of strengthening rib is 0.2mm ~0.8mm, and the minor face dimension L1 of strengthening rib is 0.3mm ~0.8mm, and the long limit dimension L2 of strengthening rib is 1.0mm ~2.0 mm.
Among the above-mentioned technical scheme, protruding thorn and strengthening rib thereof adopt the extrusion instrument extrusion steel backing surface of taking trapezoidal blade to form, and steel backing surface forms the recess after receiving the extrusion.
The utility model has the advantages that: the material on the two sides of the root of the convex thorn is used as a reinforcing rib for connecting the convex thorn and the back plate, so that the fastening strength of the connection between the convex thorn and the surface of the back plate is ensured, and the bonding strength and the friction force of the back plate and the friction material are enhanced; the protruding thorn on the steel backing distributes with the direction opposite direction that is on a parallel with rolling direction, forms stable muscle network structure, has stronger holding power, and the muscle network structure of backplate surface protruding thorn has increased the space for it, has reduced the stress point, the radiating effect in the reinforcing.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, a steel backing of commercial car reinforcing rib shape convex thorn, the equipartition has a plurality of convex thorn on the steel backing, and a plurality of convex thorn is with the direction opposite distribution who is on a parallel with rolling direction A to become a plurality of rows on the steel backing, and on same row, the direction of convex thorn is the same, and in two adjacent rows, the direction of convex thorn is opposite. The protruding thorn forms even unified muscle network structure on the steel backing, makes the steel backing have stronger holding power to the radiating effect in the reinforcing. The spurs may also employ different directional logic and are not limited to the use of the above-described oppositely distributed scheme.
As shown in fig. 2-3, the combination surface of the spur itself and the steel back has a limited load to bear, and in order to increase the strength of the combination surface, each spur is provided with a reinforcing rib at the root position connected with the steel back, and the reinforcing rib enables the spur to bear the force and vibration applied during the fracture. The convex thorns and the reinforcing ribs thereof are formed by an extrusion process, the working cutting edge part of the extrusion tool is designed into trapezoidal transition, the extrusion tool extrudes and displaces the material on the surface of the steel backing, and the surface of the steel backing forms a groove after being extruded by the extrusion tool. Most of materials on the surface of the steel back are extruded and raised upwards to form convex spines, a certain inclination angle theta is formed between the convex spines and the plane of the back plate, and the inclination angle theta is generally not more than 90 degrees. The little partial material on steel backing surface is under the work blade effect of trapezoidal transition, to both sides extrusion displacement arch formation strengthening rib, the strengthening rib is long triangle-shaped structure, the size of strengthening rib is influenced by the size of extrusion instrument's work blade, the thickness dimension D of strengthening rib is at 0.2mm ~0.8mm within range, the minor face dimension L1 of strengthening rib is at 0.3mm ~0.8mm within range, the long limit dimension L2 of strengthening rib is at 1.0mm ~2.0mm within range.
The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
