Description
Technical Field
The utility model relates to a rub and hinder the equipment, specifically become to rub formula pneumatic clutch brake with rubbing piece through one shot hot briquetting.
Background
The friction block for the pneumatic clutch brake is a key component in the pneumatic clutch brake. The existing friction block for the pneumatic clutch brake is complex to assemble, poor in installation accuracy and free of impact resistance and shock absorption functions, wherein the composite friction material and the metal framework are combined by utilizing the traditional gluing technology, namely the composite friction material is fixed on the metal framework by a method of gluing through adhesive glue. This method has the following disadvantages: (1) the molding process is complicated: the composite friction material is molded and then is bonded on the metal framework, so that the production efficiency is low; (2) the fixing strength of the friction material layer and the metal framework is insufficient: because the composite friction material layer is fixed with the metal framework completely depending on the fixing force of the bonding glue (the mechanical strength of the bonding glue is lower than that of the friction material layer), and the direction of the friction force borne by the pneumatic clutch brake part during working is parallel to the bonding surface of the metal framework, the glue layer becomes a stress concentration area to cause the phenomena of cracking and damage, the service life of the friction block for the pneumatic clutch brake is shortened, and the use cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome above-mentioned background art not enough, provide a friction piece for friction formula pneumatic clutch brake, should rub the characteristics that the piece should have intensity height, long service life and processing are convenient.
The utility model adopts the technical proposal that:
a friction block for a friction type pneumatic clutch brake comprises a metal framework and friction material layers adhered to the upper and lower bonding surfaces of the metal framework; the method is characterized in that: the upper bonding surface and the lower bonding surface of the metal framework are respectively provided with a plurality of trapezoidal grooves for reinforcing the friction material layer, and a plurality of trapezoidal raised lines matched with the trapezoidal grooves are formed on the friction material layer; the friction material layer is fixedly bonded on the bonding surface of the special-shaped metal framework through an adhesive, and the trapezoidal convex strips are filled into the corresponding trapezoidal grooves to be fixedly bonded.
The depth of the trapezoidal groove is 5-6 mm.
The left side and the right side of the special-shaped metal framework are respectively provided with a dovetail groove for installation.

Detailed Description
The friction block for the friction type pneumatic clutch brake comprises a metal framework 1 and friction material layers 2 which are bonded on the upper bonding surface and the lower bonding surface of the metal framework. The metal framework is a special-shaped metal framework, namely, dovetail grooves 4 (used for being mounted on the pneumatic clutch brake) are respectively processed on the left side and the right side of the metal framework, so that the mounting precision of the friction block on the friction type pneumatic clutch brake is improved, and the mounting is more convenient.
The upper and lower two bonding surfaces of the metal framework are respectively provided with a plurality of trapezoidal grooves 3 (the size and the distribution mode of the trapezoidal grooves can be determined as required) for reinforcing the friction material layer, and the friction material layer correspondingly forms a plurality of trapezoidal raised lines which are suitable for the trapezoidal grooves.
The friction material layer adopting the hot-press one-step forming process is fixedly bonded on the bonding surface of the metal framework through bonding glue, the trapezoidal grooves are filled and wrapped by the corresponding trapezoidal convex strips, and the trapezoidal grooves and the trapezoidal convex strips are fixedly bonded through the bonding glue. The depth of the trapezoidal groove (the distance between the groove bottom and the bonding surface) can be generally selected from 5-6 mm, and can also be determined according to requirements.
The utility model discloses a theory of operation is: because the upper and lower bonding surfaces of the metal framework are respectively provided with the trapezoidal grooves, the friction material layer adopting the hot-pressing one-step forming process also respectively forms a plurality of trapezoidal raised lines when the metal framework is hot-pressed and formed on the bonding surfaces. By the structure, not only is the fixing force generated by the adhesive between the metal framework and the friction material layer, but also the trapezoidal grooves generate extra pulling force on the friction material layer, so that the mechanical strength of the friction material layer on the metal framework is obviously improved.
