When the China Forging Machine Tool is working, the motor drives the large pulley (usually doubled as a flywheel) through the V-belt, and drives the crank slider mechanism through the gear pair and clutch, so that the slider and the punch go down in a straight line. After the forging work is completed, the slider returns upward, the clutch is automatically disengaged, and the automatic device on the crank shaft is connected at the same time, so that the slider stops near the top dead center.

The essence of roll forging deformation is the rolling extension of the billet, and the section of the billet part becomes smaller and the length increases. When the deformation of the section is large, it needs to be rolled several times by several passes. The manufacturer of China Forging Machine Tool tells you that its process design is mainly to reasonably determine the amount of reduction, width and extension of roll forging in each process step. They depend on the size of the roll diameter, the shape and size of the pass, the temperature of the blank, and the deformation conditions such as cooling and lubrication. Some double-support roll forging machines have roller shafts protruding from one end. This is a composite roll forging machine combining cantilever and double support types. It can not only realize longitudinal roll forging but also complete transverse widening at the cantilever end. In mass roll forging production, manipulators are widely used to transfer workpieces to realize the automation of the production process, improve productivity and reduce labor intensity.
Pressurize the blank placed in the die with the punch to make it produce plastic flow, so as to obtain the forging method of the workpiece corresponding to the shape of the hole of the die or the shape of the concave and convex die. The manufacturer of China Forging Machine Tool tells you that when the billet is extruded, the billet will generate three-dimensional compressive stress, even the billet with low plasticity can be extruded. Extrusion, especially cold extrusion, has high material utilization rate, improved material structure and mechanical properties, simple operation, high productivity, and can make long rods, deep holes, thin-walled, special-shaped parts, and is an important less-cutting processing technology. Extrusion is mainly used for the forming of metals, and it can also be used for the forming of non-metals such as plastics, rubber, graphite and clay billets.
Each slider-crank mechanism is called a "point". The simplest mechanical press is a single-point type, that is, there is only one crank-slider mechanism. Some mechanical presses with large working surfaces use two or four points in order to make the bottom surface of the slider evenly stressed and move smoothly.
The load of the mechanical press is impact, that is, the time of forging work in a working cycle is very short. The short-term maximum power is more than ten times greater than the average power, so a flywheel is installed in the transmission system. The manufacturer of China Forging Machine Tool tells you that after the motor selected according to the average power is started, the flywheel will run to the rated speed to accumulate kinetic energy. After the punch contacts the blank and starts the forging work, the driving power of the motor is less than the load, the speed decreases, and the flywheel releases the accumulated kinetic energy to compensate. After the forging work is completed, the flywheel accelerates again to accumulate kinetic energy for the next use.
There is a mechanical or electrical interlock between the clutch and the brake on the mechanical press to ensure that the brake must be released before the clutch is engaged, and the clutch must be disengaged before the brake is applied. The operation of mechanical presses is divided into continuous, single-stroke and inching (micro-motion), most of which are realized by controlling clutches and brakes. The stroke length of the slider remains unchanged, but the distance between the bottom surface and the working surface (called the sealing height) can be adjusted by the screw.
The manufacturer of China Forging Machine Tool tells you that during production, it may happen that the nominal working force of the press may exceed the phenomenon. In order to ensure the safety of the equipment, an overload protection device is often installed on the press. In order to ensure the personal safety of the operator, the press is equipped with a photoelectric or two-handed personal protection device.
