Safety Operating Procedures for Forging and Pressing Machines

Release time:2020-02-13
Forging and pressing machinery refers to the mechanical equipment used in forging and pressing processes for shaping and separating materials. This category includes shaping tools such as forging hammers, mechanical presses, hydraulic presses, screw presses, and flat-die forging machines, as well as auxiliary machines like decoilers, straighteners, shears, and forging manipulators. Since forging and pressing machinery is primarily used for metal forming, it is also commonly known as metal-forming machine tools. These machines work by applying significant pressure to metals to achieve their desired shapes—a defining characteristic that makes them typically heavy-duty equipment. To ensure both operational safety and worker protection, most of these machines are equipped with robust safety devices.
Safety Operating Procedures for Forging and Pressing Machines
1. Ensure the mold is intact, free of cracks, properly installed, and securely fastened.
2. Clear debris from the slider travel space and mold cavity.
3. Before starting the main motor, first test the clutch’s solenoid valve to ensure that the valve operates correctly and that the clutch and brake functions are accurate, responsive, and reliable. Only after this verification should the main motor be started. Additionally, the rotation direction of the main motor must match the specified direction.
4. When adjusting the closing height, strictly follow the adjustment procedures and methods specified in the instruction manual. Additionally, never energize the main motor while adjusting the bottom feeding mechanism.
5. After performing an empty run test, replacing the mold, or adjusting the closing height for speed control, the slide must be operated in "inch mode" for its first stroke only. The procedure is as follows: Briefly start the main motor, then immediately stop it—allowing the flywheel to carry the momentum—and use "inch mode" to move the slide. Check whether the mold’s closing height and concentricity are properly aligned. Once you’ve confirmed everything is correct, proceed with the following operational steps in sequence: "inch mode," "single stroke," and finally "continuous operation."
6. When the slide is in operation, do not reach your head or hands into the enclosed space of the die. Also, never use pliers to correct, retrieve, or place forged parts inside the die. Regularly clean off oxide scale from the die surface.
7. Regularly check the condition of the mold; if any looseness is detected, tighten it immediately.
8. When placing the forging blank into the die or removing the forged part from the die, never place your feet on the power pedal.
