The working principle of a hydraulic press is based on the crankshaft and connecting rod mechanism, the flywheel is driven by the motor, the flywheel drives the big gear through the shaft and pinion, the big gear drives the crankshaft through the clutch, and the crankshaft drives the connecting rod to make the slider work. The number of strokes per minute of the slider and the motion curve of the slider is fixed. The press can be basically divided into a bed part, a working part, a control part, and a transmission part. All components of each part are installed on the bed. Hydraulic punch presses are general-purpose presses for sheet metal stamping, which can realize various cold stamping processes, such as punching, bending, and shallow drawing.
⑴Bed part: The bed and the worktable are cast iron parts
⑵Clutch: When the press is not working, the cam of the manipulator blocks the tail of the turning key, so that the crescent fox of the working part is completely plunged into the semicircular groove of the crankshaft. At this time, the crankshaft is idling, and the slider stops at the top dead center; when the press is working, the cam of the manipulator rotates an angle to let the tail of the open turn-key, acted by the spring, the turn key rotates 45°, and the back of the working part enters the middle sleeve In any one of the three circular grooves, the clutch is in the combined position, the flywheel drives the crankshaft to rotate, and the slider moves up and down.
⑶Slider: In the slider, there is a pressure pedal type safety device under the ball bowl contacting the ball head of the adjusting screw to ensure that the press will not be damaged when overloaded. Open the square cover on the front to change the safety device.
⑷Brake band: An eccentric brake band is installed at the left end of the crankshaft. When the clutch is disengaged, it overcomes the inertia of the slider's reciprocating motion and ensures that the crankshaft stops at the top dead center.
⑸Manipulator: The mechanism that controls the coupling and disengagement of the clutch when the manipulator is used. Switch the connecting position of the lever of the manipulator to obtain two actions of a single stroke and continuous stroke.
⑴After the hydraulic punch is leveled, install the anchor bolts, and refill the concrete. After the concrete is completely solidified, evenly tighten the anchor bolt nuts, and then use a level to recalibrate the level of the workbench. The grounding wire should be properly connected.
⑵The hydraulic punch must be completely solidified before it can start working.
⑶After the hydraulic punch is installed, use kerosene to wash off the anti-rust grease on the surface of the hydraulic punch. When cleaning, be careful not to damage the painted surface. At the same time, clean the oil holes, oil channels, and oil marks, and keep them clean. Do not use metal when scrubbing Or emery cloth.
It converts circular motion into linear motion. The main motor generates power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc., to achieve the linear motion of the slider, from the main motor to the connecting rod. For a circular motion. Between the connecting rod and the slider, there is a transition point for circular motion and linear motion. There are roughly two mechanisms in its design, one is ball type, the other is pin type (cylindrical type), through which the circular motion is Converted into linear motion of the slider.
