Description
Technical Field
The invention relates to a double-power support connecting rod boosting type brake device of a large-tonnage friction press, which can be widely applied to the large-tonnage double-disc friction press.
Background
When the large-tonnage double-disc friction press stops working, the large flywheel is changed from a rotating state to a static state. Because of the large-tonnage friction press, the large flywheel has large volume and large generated torque, and the rotation of the large flywheel can be braked by large thrust. The existing brake device is braked by a spring or a lever mechanism only, so that a large flywheel is difficult to brake and stop at an accurate position.
Disclosure of Invention
The invention aims to provide a double-power support connecting rod boosting type brake device of a large-tonnage friction press, which has the advantages of sensitive braking, large braking force, reliable braking and safe braking.
In order to achieve the above purpose, the double-power support connecting rod reinforcement type braking device of the large-tonnage friction press comprises a braking frame, a braking cylinder body, a braking piston, a piston rod, a braking spring, a spring stop block, a spring fastening nut, a nut cap type connector, a back fastening nut, a support connecting rod and a support connecting rod, wherein the braking cylinder body is provided with a braking brake air inlet and a braking opening air inlet and is hinged with the braking frame, the braking piston is arranged in the braking cylinder body, the piston rod is arranged on the braking piston, the braking spring stop block is close to the braking spring and is arranged on the piston rod, the nut cap type connector is tightly close to the spring stop block and is in threaded connection with the piston rod, the nut cap type connector is in threaded connection with the tail end of the piston rod, the back fastening nut is arranged on the inner side surface of the nut cap and is in threaded connection with the piston rod and is used for fastening the nut cap type connector, one end of the support connecting rod is hinged with the braking frame, the brake comprises a boosting connecting rod hinged with the nut cap type connector, a boosting lever hinged with the boosting connecting rod, and a brake plate hinged with the boosting lever and used for braking the large flywheel.
The invention relates to a double-power support connecting rod reinforcement type braking device of a large-tonnage friction press, which has the working principle that: when the large-tonnage double-disc friction press works, when the air inlet is opened for air inlet through braking, the brake spring is compressed, the brake plate is separated from the large flywheel, and the large flywheel is in a rotating state to generate rotating torque. When the large-tonnage double-disc friction press stops working and the air inlet of the brake is filled with air, the support connecting rod and the force-increasing connecting rod are pushed to move forwards under the dual power action of compressed air and the brake spring, the brake thrust is transmitted to the brake plate through the connecting rod and the lever force-increasing mechanism formed by the force-increasing connecting rod and the force-increasing lever, the brake plate is pushed to rotate forwards, the large flywheel is pressed tightly, and the large flywheel stops rotating, so that the braking effect is achieved.
According to the double-power support connecting rod boosting type brake device of the large-tonnage friction press, the large flywheel is braked by the combined acting force of the brake spring and compressed air, the brake is sensitive, the connecting rod and the lever boosting mechanism further amplify the brake force according to the lever principle, the brake force is large, the brake is reliable, and the brake is safe.
In conclusion, the double-power support connecting rod boosting type braking device of the large-tonnage friction press is sensitive in braking, large in braking force, reliable in braking and safe in braking.
