The invention provides an automatic bending forming mechanism for a push type multi-piece annular paper-based friction plate, and belongs to the field of automobile part manufacturing. The automatic bending forming mechanism comprises an equipment fixing seat, a driving mechanism, a feeding mechanism, a material-bending mechanism and a feed mechanism, and the equipment fixing seat is of a frame structure and used for supporting and fixing each part in a whole forming mechanism; the feeding mechanism is composed of a material storage box, a material-pushing plate and an inserting plate, and theinserting plate inserts friction materials into a material-bending groove; the material-bending mechanism is composed of material-bending sliding block, a pull rod and the material-bending groove, the material-bending sliding block pushes the friction materials to a shaping mould under the action of the pull rod, and the friction materials are bent from straight; and the feed mechanism is composed of feed inserting teeth and the shaping mould, the feed inserting teeth push the friction materials downwards, so that the friction materials have the taper required by a ring gear, and the frictionmaterials are changed to the size required by the ring gear. According to the automatic bending forming mechanism for the push type multi-piece annular paper-based friction plate, the defect that thepaper-based friction materials are prone to being cracked in the manual bending process is overcome, the productivity is improved, an auxiliary attached mechanism is used in a matched mode, and attachment of synchronizer ring gear paper-based friction materials can be realized.
Description
technical field [0001] The invention belongs to the field of automobile parts manufacturing, and in particular relates to a push-type multi-piece annular paper-based friction plate automatic bending forming mechanism. Background technique [0002] The synchronizer is a very important part in the automobile transmission. Its function is to make the gears to be meshed reach a consistent speed and then mesh smoothly. The synchronizer is divided into normal pressure type, inertia type and self-energizing type. At present, friction inertia synchronizer is widely used , The inertial synchronizer is synchronized by friction, and the ring gear is the core component of the synchronizer to achieve friction. [0003] At present, the most commonly used gear ring is the attached gear ring, that is, a layer of friction material is attached to the friction surface. The friction material used is carbon fiber cloth, which has many excellent properties, but the cost of carbon fiber cloth is e...
