Friction press for dry-pressing molding of fire-resistant high-hardness material

Abstract

The invention discloses a friction press for dry-pressing molding of a fire-resistant high-hardness material. The friction press comprises symmetrically-arranged supports. A base is arranged between the bottoms of the supports. A lower forging-pressing molding mold is arranged at the upper end of the base. An L-shaped frame is arranged between the top ends of the supports. Through the cooperationarrangement of an electromagnet, an iron block, a pushing rod and an L-shaped plate, a supporting plate and a driving friction wheel can be driven to get close to a flywheel to apply acting force to the flywheel. Through spring elastic force, the supporting plate and the driving friction wheel can be driven to get away from the flywheel and do not apply acting force to the flywheel again. Throughthe arrangement of a brake mechanism, braking can be carried out on rotation of a driven shaft. Through braking on rotation of the driven shaft, the braking effect can be carried out on rotation of the flywheel reversely. According to the friction press, through the brake mechanism is used for braking rotation of the flywheel from the two manners of braking on a driven friction wheel and cutting off on the acting force of a driving friction wheel to the flywheel, the braking effect on equipment is increased, production safety is improved, and the accident of hurting hands is avoided.

Description

Technical field [0001] The invention relates to the technical field of refractory material production equipment, and the specific field is a friction press for dry pressing and forming of refractory high-hardness materials. Background technique [0002] Friction press is a kind of screw press with friction drive method, also known as double disc friction press. The press production group of metal forging workshop is the press production group of metal forging workshop. It uses the contact transmission of flywheel and friction disc. It works with the principle of relative movement between screw and nut. Because of its versatility in use, and its advantages of simple structure, installation, operation and auxiliary equipment and low prices, it is used in press workshops, forging workshops and die forging workshops in machinery manufacturing, automobiles, tractors, and aviation industries. They are widely used and can also be punched. Friction presses are also building materials m...

Problems solved by technology

Traditional equipment is likely to cause personal injury accidents such as broken fingers. This uses a cam mechanism to engage or disengage the clutch. Once engaged, it must complete a cycle before stopping.

If the hand cannot be pulled out from the mold in time during this cycle, hand injury accidents will inevitably occur, and the effect of braking the rotation of the flywheel with the braking device alone is not very satisfactory, even if the drive motor no longer generates power due to the drive motor. The rotational inertia will still exert force on the flywheel to make it continue to rotate, without timely and immediate braking effect, which is likely to cause safety hazards
