Gear transmission clutch high power screw press

Abstract

The invention relates to a gear transmission clutch high power screw press. The gear transmission clutch high power screw press comprises a machine body, a main flywheel is mounted on the top of the machine body horizontally, the main flywheel is connected with a screw vertically mounted in the middle of the machine body, a sliding block is mounted on the bottom of the screw, a descending clutch system for driving the main flywheel to rotate forwards is mounted on the top of the machine body, a return clutch system used for driving the main flywheel to reversely rotate is mounted on the top ofthe machine body, and a flywheel brake system is mounted on the main flywheel. The screw press has the advantages that the clutch slip problem during hitting can be removed, equipment control is precise, hitting energy is large, electric energy is saved, the service life is long, maintaining cost is low, and safety and reliability are achieved.

Description

Technical field: [0001] The present invention relates to a kind of press machine, more particularly it relates to a kind of high-energy screw press machine of gear drive clutch. Background technique: [0002] At present, the technology of presses has been brought forth from the old to bring forth the new, and has gone through several generations of development: the driving principle of the first generation of friction presses is that the vertical friction disc drives the middle flywheel to rotate, and the flywheel and the screw are tightly connected to realize the up and down movement of the slider and complete the impact. However, this device has serious disadvantages: the contact area between the friction disc and the flywheel is small, the transmission torque is limited, the acceleration time of the flywheel is too long, and the device cannot precisely control the striking energy and cannot be biased. [0003] The second generation is hydraulic and electric screw presses....

Problems solved by technology

[0002] At present, the technology of presses has been brought forth from the old to bring forth the new, and has gone through several generations of development: the driving principle of the first generation of friction presses is that the vertical friction disc drives the middle flywheel to rotate, and the flywheel and the screw are tightly connected to realize the up and down movement of the slider and complete the impact. However, this device has serious disadvantages: the contact area between the friction disc and the flywheel is small, the transmission torque is limited, the acceleration time of the flywheel is too long, and the device cannot precisely control the striking energy and cannot be biased

However, there are also many shortcomings: due to the difficulty in manufacturing high-torque hydraulic motors, low hydraulic transmission efficiency, and more leakage, hydraulic screw presses have not been widely promoted

But there are very serious disadvantages: 1. When the blow ends, the speed of the slider and the screw tends to zero, while the speed of the flywheel basically remains unchanged at a high speed, and it takes a certain amount of time for the clutch to disengage, which causes each working cycle to occur. The clutch slips under full load, and the life of the clutch is greatly reduced

2. In order to make the clutch transmit a large torque, the clutch is generally driven by multiple oil cylinders. The rated torque of the clutch can only be achieved under the joint action of dozens of oil cylinders. Too many hydraulic actuators provide a large number of hidden dangers. If the leaking hydraulic oil comes into contact with the blank with a temperature of more than 1000 degrees, it will catch fire instantly, causing great danger and posing a great safety hazard
