Abstract
The present invention belongs to the technical field of preparing techniques of brake blocks, which particularly to discloses a preparation process and a special device of a disk-type brake block. The process for preparing the disk-type brake block has the processing steps of steel back preparation, liner material preparation, cold briquetting, hot pressing, solidification and heat treatment. Because the cold briquetting of the brake block is added in the process, the present invention has the advantages that thermal stress distribution of the inner structure of the prepared brake block is uniform, the defects of expansion, crazing, etc., in the process of using are overcome, and the brake block prepared by the process also has the characteristics of low cost and high productive efficiency.
Description
Technical field
The invention belongs to the preparing technical field of brake block, disclose a kind of preparation process of disc brake pad specifically.
Background technique
At present, the preparation of disc brake pad has two kinds of technologies.A kind of technology---as the disclosed technology of patent of invention that the patent No. is 96115295.8, notification number is CN1165255, name is called a kind of brake block.The preparation section of its brake block is: the tailoring of steel backing, the kneading of brake block liner, raw material comprise the pretreatment of drying, pulverizing, in the mould of preheating coating release agent, dose behind the steel backing that scribbles tackiness agent and the pretreated liner material operations such as the heating pressurization is once hot-forming.Utilize this technology to prepare disc brake pad and then have following shortcoming: the mold filling operation in this technology is the batch mixing of the liner of powdery directly to be inserted to heat with steel backing in the mould be bonded together, because the heat transfer inequality of the liner batch mixing of powdery, temperature gradient is big, can make the powdery batch mixing can not get the even variation of uniform chemical reaction and physical form, cause the brake block internal structure thermal stress distribution inequality prepared, the brake block of preparing in use easily produces and expands and unconquerable defectives such as be full of cracks; Although this technology makes the brake block once-through since the mould of preparation brake block too thick and heavy, make that hot pressing time is long, power consumption is high, therefore also exist the low defective of manufacturing efficiency (manufacturing mechanism can only produce about 20/hour).The preparation process's of another kind of brake block manufacturing process is: tailor the batching of steel backing, brake block liner and batch mixing, the brake block liner is hot-forming, with tackiness agent the two is bonded together then.Utilize this technology to prepare disc brake pad, in use then exist steel backing and the caducous defective of brake block liner.
Summary of the invention
Purpose of the present invention just provides that a kind of brake block internal structure thermal stress distribution is even, the preparation process of the simple disc brake pad of technology.
Another object of the present invention just provides the special device of the high preparation disc brake pad of a kind of manufacturing efficiency.
The preparation process who realizes a kind of disc brake pad proposed by the invention includes following operation:
The preparation of first step steel backing
Tailor steel backing, the surface is handled and coating adhesive;
The preparation of the second step liner material
To the material that liner is required pulverize, pretreatment such as drying, mixing;
The 3rd step cold moudling
In the die cavity that the liner material for preparing and steel backing are inserted mould, compression moulding;
The 4th step hot-press solidifying
The brake block of cold moudling is inserted hot-press solidifying in the vulcanization die;
The 5th step heat treatment
The brake block of sulfidization molding is heat-treated.
The special device that uses in the technology of above-mentioned preparation disc brake pad comprises: the sulfuration mechanism of cold moudling mechanism and hot-press solidifying.
Wherein, described cold moudling mechanism comprises pressure mechanism and platform, and described pressure mechanism is provided with at least one patrix, is fixed with the displaceable counterdie corresponding with patrix on the described platform, and described platform is provided with positioning means and type hole; The structure of the sulfuration mechanism of described hot-press solidifying comprises pressure flat and working platform, the two is provided with several layers and is connected with the heating plate that thermal source has heating function, and the Die and mould plate that has some die cavitys can insert and finish the sulfidization molding that places the die cavity brake block between described heating plate; Be connected with drawing mechanism between the heating plate in the sulfuration mechanism of described hot-press solidifying.
The preparation process of disc brake pad provided by the present invention and special device, compared with prior art have the following advantages: one, because before brake block is hot-forming, carry out cold moudling after having increased dusty material mold filling with the brake block liner, and make the brake block liner under physical condition, be compressed the operation that is bonded on the steel backing, therefore internal heat transfer is even when making the brake block of moulding be heating and curing sulfuration, temperature gradient is less, the brake block internal structure thermal stress distribution of preparing is even, has avoided in use easily producing the defective of phenomenons such as expansion and be full of cracks; They are two years old, when being heating and curing vulcanizing treatment again after brake block colded pressing earlier, the thickness of hot pressing die is 1/3rd of one-shot forming technique mold thickness, therefore transmission of heat is accelerated when the brake block liner of moulding being heating and curing, the time of whole hot-press solidifying is 1/2nd of one-shot forming technique only, and power consumption reduces greatly; Its three, the equipment that this technology provides can be so that be heating and curing the operation continization, the hydraulic press suitable with one-shot forming technique once can be heating and curing to the brake block liner of 60 (about 120/hour) at least, improved manufacturing efficiency greatly.
