Abstract
The invention relates to the technical field of production of steel backing of disc brake pads, and discloses a manufacturing method of the steel backing of the disc brake pad. The method involves a punching forming die which comprises a lower die bottom plate, wherein the lower die bottom plate is matched with a lower die; two steel backing cavities are formed in the lower die; the inner sides of the two steel backing cavities are opposite to each other; a clearance between the two steel backing cavities is not greater than 4mm to the maximum; two convex dies which are used in match with the steel backing cavities are fixed at the bottom part of the upper die. The method comprises the steps of 1, fixing the lower die bottom plate of the punching forming die and the lower die on a punch press stand; 2, horizontally paving boards to be above the lower die, and automatically pushing steel boards to move forwards under the combination of the board feeding ends and an external automatic feeding machine; 3, punching by the matching of the convex dies and the steel backing cavities of the lower die; 4, checking whether steel backing billets are accumulated in the steel backing cavities all the time by an operator; if so, timely stopping to remove. With the adoption of the method, the steel backing of the disc brake pad can be quickly formed, thus the waste can be effectively decreased, and as a result, the cost is reduced.
Description
Technical field
The present invention relates to brake block steel back production technical field, more particularly, relate to a kind of disc type brake block steel back preparation method.
Background technology
As everyone knows, frictional force is produced by pressurizeing between the brake block that brake process is mainly fixed and the brake disc with vehicle wheel rotation, reach the object of brake, frictional force is that friction material and brake disc rub and produce, a power stops vehicle wheel rotation and brakes, contrary power effect produces moment of torsion onboard, and this power is delivered on car by steel backing.
Brake block steel back is for fixed car brake friction material, is convenient to brake block and is arranged in brake system.In current common vehicle is on the market all steel matter, in processing and making process, need use steel plate cutting machinery that steel plate is cut into strip, then by punch press, monolithic brake block steel back blank is swept away, in process, many people need be used to operate, efficiency is low, and in steelplate punching process, after monolithic stamping-out, waste material produces many, wastes raw material.
Summary of the invention
For overcoming the deficiency in existing production technology, the invention provides a kind of disc type brake block steel back preparation method, it is reasonable in design, achieves multiple steel backing and processes simultaneously, and economize in raw materials in process, the high danger coefficient that also can effectively reduce in operation labour intensity and operating process of stamping-out efficiency.
For realizing above-mentioned technical purpose, the present invention adopts following scheme: a kind of disc type brake block steel back preparation method, it possesses one and rushes forming mold, described mould comprises a lower mould bottom plate, lower mould bottom plate is matched by the locating dowel on the locating hole of corner and die, with this, die is located, die has two steel backing die cavities, inside two steel backing die cavities relatively; Be patrix directly over die, the bottom of patrix is fixed with two punch be used in combination with steel backing die cavity, the size of punch with can vertically insert with steel backing die cavity and must not gap more than 0.05 millimeter for standard, the top of patrix is die shank.
Punch and die need use CR12 mould steel to make, and need heat treatment after making, and after heat treatment, hardness must not lower than more than HRC56.
Coordinate above-mentioned mould, method of operating of the present invention is:
1. the lower mould bottom plate of stamping-out mould and patrix are fixed on punch press board, are adjusted to punch and vertically can be inserted as standard with die;
2. tiled above counterdie by sheet material, sheet material feed end promotes steel plate reach automatically in conjunction with outside autoloader, and patrix coordinates punching material;
3. the steel backing die cavity of punch and die coordinates punching material, need ensure punch sharpness, with stamping-out 5 mm of thickness steel plate for standard, after stamping-out 20000 times, punch and die surface grinding machine need be ground cutting edge.
4. the steel backing die cavity of punch and die coordinates punching material, and operator need check in steel backing die cavity and block with or without steel backing, if having, need shut down removing in time.
Beneficial effect of the present invention is: the present invention is by increasing counterdie area, and be two by the steel backing cavity design on counterdie, and it is corresponding inside two steel backing die cavities, outside autoloader is coordinated automatically to promote steel plate reach, the stamping-out speed of brake block steel back is accelerated greatly, effectively reduces the generation of waste material, saved manual operation, effectively reducing brake block steel back cost of manufacture and significantly improve handling safety coefficient, is a kind of desirable disc type brake block steel back preparation method.
