Technical field
The present invention relates to a kind of manufacturing technology of steel backing of vehicle brake block, be specifically related to a kind of brake block steel back enhancing friction base material fixation.
Background technique
Existing automobile brake sheet is generally combined into by brake block steel back and brake pad, and friction material is bonded by reinforcing material, tackiness agent and filler etc.; Brake block steel back plays fixed support brake pad.During brake, brake block steel back is by the promotion of braking clamp, brake pad and brake disc rubbing contact, is reached the object of vehicle deceleration by friction, simultaneously in the process of braking, can produce very strong shearing force between friction material and brake block steel back.So, generally require the intensity that is adhesively fixed that friction material and steel backing reach certain, prevent from brake process, occur that friction material comes off from brake block steel back, produce brake failure.
Existing brake block steel back is in order to have employed various structures with friction material secure bond:
Such as at the surface soldered wire netting of brake block steel back, such structure is by the welding of two kinds of different materials, welding effect is unstable, and welding manner is the spot welding on wire netting bar and steel backing surface, be easy to occur that part soldering point loosens and causes the potential safety hazard in using process, manufacturing procedure more complicated simultaneously, cost of production is higher.
Such as adopt the brake block steel back of casting, the sink deck on it has multiple boss of contact with brake pad or groove, increase and the area of contact of brake pad, after die casting molding, error is large, need secondary operations to realize mating with brake pad, production process is complicated, and cost of production is high.
Summary of the invention
In order to solve the technical problem existed in background technique, the present invention proposes the brake block steel back that a kind of production process is simple, cost of production is low.
The present invention proposes a kind of brake block steel back, comprises a plate body with steel back structure formed by steel plate punched, and in the front punching press of plate body along the groove of its shear direction matrix arrangement, the longitudinal section of groove is trapezoidal, and the base area of groove is 0.8-2.4mm
2, the opening angle of groove is 15-25 °, and the degree of depth of groove is 0.8-1.2mm, and the spacing between groove and groove is 1-4mm; In the central position punching press abnormity sink deck in plate body front, sink deck is perpendicular to the shear direction of plate body at least being arranged a buckle face vertical with plate body, the degree of depth of sink deck is 1.5-2.5mm, is provided with the abnormity that arrange corresponding to sink deck protruding at the back side of plate body; The plate body of sink deck both sides is provided with the auxiliary hole be arranged symmetrically with, and the center line of sink deck and the shaft axis of auxiliary hole are positioned on same longitudinal section; Pilot hole is equipped with in the upper center of plate body and both sides, be symmetrical arranged two in the lower end of plate body and connect ear, connect between ear and be provided with the excessive face of the circular arc caved in inside plate body, the back side of connection ear is provided with the stud for installing warning spring, and described stud is by making at plate body front punching press counterbore.
Preferably, the cross section of groove is rectangle or circular or square and circular combination.
Preferably, shoal gradually from plate body top to the degree of depth of the lower recess of plate body, groove is large compared with deeply putting spacing between groove, and the more shallow point of groove, between groove, spacing is large.
Preferably, the area of sink deck accounts for the 0.25-0.35 of plate body front face area doubly.
Preferably, the excessive face of circular arc and plate body tangent, improve the join strength connected between ear and plate body.
The present invention adopts a plate body with steel back structure formed by steel plate punched, then stamped recess, special-shaped sink deck, auxiliary hole and stud successively on plate body, and production process is simple, cost of production is low; Stamped recess on plate body, sink deck increase the area of contact of plate body and tackiness agent, the stamped recess in sink deck, the shear plane of maximized increase friction material and steel backing, increase shear strength; The present invention have durable, sensitivity strong, can the advantages such as automobile braking safety be provided.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of a kind of brake block steel back that the present invention proposes.
Fig. 2 is the structure schematic diagram of a kind of brake block steel back that the present invention proposes.
Embodiment
As shown in Figure 1 and Figure 2, Fig. 1 is the Facad structure schematic diagram of a kind of brake block steel back that the present invention proposes; Fig. 2 is the structure schematic diagram of a kind of brake block steel back that the present invention proposes.
With reference to Fig. 1-2, a kind of brake block steel back that the present invention proposes, comprises a plate body 1 with steel back structure formed by steel plate punched, in the front punching press of plate body 4 along the groove 13 of its shear direction matrix arrangement, the longitudinal section of groove 13 is trapezoidal, and the base area of groove 13 is 0.8-2.4mm
2, the opening angle of groove 13 is 15-25 °, and the degree of depth of groove 13 is 0.8-1.2mm, and the spacing between groove 13 and groove 13 is 1-4mm; In the central position punching press abnormity sink deck 14 in plate body 1 front, sink deck 14 is perpendicular to the shear direction of plate body at least being arranged a buckle face vertical with plate body, the degree of depth of sink deck 14 is 1.5-2.5mm, the area of sink deck 14 accounts for the 0.25-0.35 of plate body front face area doubly, is provided with the abnormity projection 141 that arrange corresponding to sink deck at the back side of plate body 1; The plate body of sink deck 14 both sides is provided with the auxiliary hole 15 be arranged symmetrically with, and the center line of sink deck 14 and the shaft axis of auxiliary hole 15 are positioned on same longitudinal section; Pilot hole 11 is equipped with in the upper center of plate body 1 and both sides, be symmetrical arranged two in the lower end of plate body 1 and connect ear 12, connect between ear 12 and be provided with the excessive face of the circular arc caved in inside plate body, the excessive face of circular arc and plate body tangent, the back side of connection ear 12 is provided with the stud 16 for installing warning spring, and described stud 16 is by making at plate body front punching press counterbore 161.
In a particular embodiment, the cross section of groove 13 is rectangle, and under same cross-sectional is long-pending, cross section is the girth that the girth of rectangle is greater than that cross section is circle, adopts rectangle then to add the area of contact of steel backing and tackiness agent.Shoal gradually from plate body 1 top to the degree of depth of the lower recess 13 of plate body 1, in order to preventing board body deformability, the darker local groove interval of groove 13 is larger, the local groove interval that groove 13 is more shallow is less, like this, plate body 1 top large with the adhesion of brake pad, effectively prevents brake pad to come off the brake failure produced; The present invention is when punching press sink deck 14, and part stamped recess 13 is with sink deck 14 punching press, and in guarantee bonding strength simultaneously, the shear plane of maximized increase friction material and steel backing, increases shear strength.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
