The invention relates to a pneumatic pressurization compensation type hot die forging press, wherein a pneumatic pressurization compensation system comprises a gas storage tank arranged at the top of a press body, a brake pipeline connected with the air inlet of the brake shell and the air storage tank, a brake electromagnetic valve arranged on the brake pipeline, a start end clutch pneumatic pipeline connected with the gas storage tank, a start end three-way joint arranged on the start end clutch pneumatic pipeline, a clutch normally open pipeline connected with the starting end three-way pipe joint, a clutch normally open electromagnetic valve arranged on the clutch normally open pipeline, a pneumatic pressurization compensation pipeline connected with the start end three-way pipe joint, a clutch pressurization valve and a clutch normally-off electromagnetic valve which are sequentially arranged on the pneumatic pressurization compensation pipeline, the pneumatic booster compensation pipeline comprises a terminal three-way joint connected with the clutch normally-open pipeline and the pneumatic booster compensation pipeline, and a terminal brake pipeline connected with the terminal three-way joint and the clutch rotary joint.

The invention relates to a pneumatic pressure boost compensation type hot die forging press, which has the working principle that: (1) the flywheel is driven to rotate by a small belt pulley on the motor through a triangle belt, a clutch piston presses against a clutch friction block, so that a clutch disc and the flywheel rotate together to drive the crankshaft to rotate, the crankshaft rotates to drive the sliding block to move from 0 degree of an upper dead point of the crankshaft to 180 degrees of a lower dead point of the crankshaft, and then the sliding block returns to the upper dead point, and a working cycle is completed. Under the normal working condition of the press, the normally-off electromagnetic valve of the clutch is always in a power-off closing state, and the pneumatic pressurization compensation pipeline is in an unvented state. Only when a signal that the press is to be closed is received, the normally-off electromagnetic valve of the clutch is electrified, and at the moment, gas enters the clutch through the pneumatic pressurization compensation pipeline.

(2) When the slide block is at the top dead center position, the brake electromagnetic valve and the clutch normally-on electromagnetic valve are powered off, the brake electromagnetic valve and the clutch normally-on electromagnetic valve are in a closed state, compressed air to the clutch and the brake is closed, and the flywheel runs idle. Under the pressure of a brake spring, a brake press ring presses a brake friction block on a friction surface of a brake housing through an intermediate brake annular piston. The brake friction disc is fixedly connected with the crankshaft through the expansion sleeve, so that the crankshaft stops rotating. And after the compressed air of the clutch is closed, the clutch piston enables a clutch friction block to be disengaged under the action of a clutch spring, a clutch disc fixed on the crankshaft is disengaged from a flywheel friction surface, a right steel sleeve is fixed on the machine body, a left bearing and a right bearing are arranged on the outer diameter of the right steel sleeve, and the flywheel runs idle at the moment.

(3) When the press sliding block strikes the forge piece, the brake electromagnetic valve and the clutch normally-on electromagnetic valve are electrified simultaneously, and compressed air enters the brake and the clutch working cavity. After the gas enters the brake, the thrust of the annular piston of the brake is greater than the brake spring force, the brake press ring disengages from the brake friction block, and the brake is released. Meanwhile, compressed air enters the inner cavity of the clutch cylinder body through the clutch rotary joint, pushes the clutch piston to press the clutch friction block, the motion is transmitted to the crankshaft through the clutch disc connected with the key, the crankshaft rotates, and the slide block connected with the crankshaft is driven to move downwards through the connecting rod. When the sliding block moves to a bottom dead center, the electromagnetic valve is normally switched on and switched off, the compressed air is closed, the clutch piston disengages from the clutch friction block under the action of the spring force of the clutch, at the moment, the flywheel strikes a workpiece by using the stored energy, and the forging piece absorbs the energy and then is forged and formed. When the crankshaft rotates to 270 degrees, the electromagnetic valve of the brake is powered off, compressed air of the brake is closed, the brake spring of the brake starts braking, the crankshaft runs to the top dead center position, the sliding block stops rotating, and a working cycle is completed.

The invention relates to a pneumatic supercharging compensation type hot die forging press, which adopts a pneumatic supercharging compensation system. In the forging process of the press, when overload occurs, after a control system collects signals, the clutch normally-off solenoid valve is electrified, at the moment, compressed air of a clutch pressure increasing valve is connected, pneumatic pressure can be increased by 1 time, a pneumatic pressure increasing compensation pipeline is ventilated, the compressed air enters an inner cavity of a clutch cylinder body through a clutch rotary joint, a clutch piston is pushed to press a clutch friction block, a clutch disc drives a crankshaft to rotate, at the moment, a flywheel is recombined, and under the drive of obtaining large torque and power, the slide block is rapidly separated from an overload area, the phenomenon that the press is blocked due to overload is prevented, the operation is safe and reliable, the service life of equipment is long, and the personal safety of operators is guaranteed.

In conclusion, the pneumatic pressurization compensation type hot die forging press machine provided by the invention has the advantages that the phenomenon of vehicle stuffiness caused by overload of the press machine is prevented, the operation is safe and reliable, the service life of equipment is long, and the personal safety of operators is guaranteed.
