The principle of hot forging press

< p="">        Die forging is mold casting. The forgings must be cooled by a press before being cooled. Therefore, the cold die forging press is cast by a press and then cooled by a die. The press is usually a pneumatic, hydraulic, crank-type press, but crank presses are often used for cold stamping because of the lack of useful strokes. For example, in terms of utilization, some auto parts need to be processed by a cold forging machine. For example, turn a part.

      How hot forging presses works:

      When the motor rotates, it is transmitted to the crankshaft through the pulley and the gear, and then the wedge is driven by the connecting rod to make the slider reciprocate up and down along the guide rail. The height of the adjusting device is adjusted by the eccentricity attached to the big end of the connecting rod. Worm gear to achieve.

      Hot forging press is a series of products imported from the world's advanced technology. The hot forging press is used in the manufacturing of automobiles, tractors, internal combustion engines, ships, aviation, mining machinery, petroleum machinery, hardware tools, etc., for batching a large number of die forging and finishing forgings of black and non-ferrous metals, forging The forgings have high precision, high material utilization rate, high productivity, easy automation, low requirements on workers' technical requirements, low noise and vibration, etc. Therefore, they are widely used in modern forging production, and are not suitable for modern forging production. Missing high precision forging equipment.

      When the mechanical press is working, the motor drives the large pulley (usually also as a flywheel) through the V-belt. The gear pair and the clutch drive the crank slider mechanism to make the slider and the convex The mold goes straight down. After the forging operation is completed, the slider returning clutch is automatically disengaged, and the brake on the crankshaft is turned on, so that the slider stops near the top dead center. Each crank slider mechanism is called a "point". The simplest mechanical press uses a single point, ie only one crank slider mechanism. Some large working surface mechanical presses use double or four points for uniform force and smooth motion of the bottom surface of the slider.   The load of the mechanical press is impacty, that is, the time for forging work in a working cycle is very short.
