The working principle and precautions of high-speed punching machine

Working principle

The design principle of the punch press is to convert circular motion into linear motion. The main motor generates power to drive the flywheel. The clutch drives gears, crankshafts, connecting rods, etc., to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is Circular motion. Between the connecting rod and the slider, there needs to be 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, through which circular motion is converted into slider Linear motion.

The punch presses the material to deform it plastically to obtain the required shape and accuracy. Therefore, it must be matched with a set of molds (upper and lower molds), the material is placed in between, and the machine applies pressure to deform it, The reaction force caused by the force applied to the material during processing is absorbed by the punch machine body.

Precautions for the safe use of high-speed punches

Before work

(1) Check the lubrication of each part, and make each lubricating power fully lubricated;

(2) Check whether the mold installation is correct and reliable;

(3) Check whether the compressed air pressure is within the specified range;

(4) The flywheel and clutch must be disconnected before the motor can be turned on;

(5) When the motor is started, check whether the rotation direction of the flywheel is the same as the rotation mark;

(6) Let the press perform several idle strokes to check the working conditions of the brake, clutch, and operating parts.

At work

(1) The manual lubricating oil pump should be used to pump lubricating oil to the lubrication point regularly;

(2) When the performance of the press is not familiar, it is not allowed to adjust the press without authorization;

(3) It is prohibited to punch two layers of sheets at the same time;

(4) If the work is found to be abnormal, stop work immediately, and check-in time.

After work

(1) Disconnect the flywheel and clutch, cut off the power supply, and release the remaining air;

(2) Wipe the press clean and apply anti-rust oil on the work surface;

(3) Make a record after each operation or maintenance.
