The technological operation process and steps of the slitting machine

Source:     Time:2021-09-02 Hits:

Slitting machine is a complex group of CNC machine tools. Its process operation steps are also relatively complicated, and the accuracy and sequence requirements of the steps are relatively strict. This requires the operator of the slitting machine to keep the operating steps in mind. Let's repeat the process and steps of the process operation of the slitting machine.


1. Before starting the machine, the job preparations to be done first have the following aspects:


(1) Prepare various production tools that may be used, and check whether there are bolts on each guide plate.

    

(2) It must be confirmed that the buttons of the operation console are in the zero position and that there are no obstacles around the machinery and equipment.

    

(3) After confirming that it is correct, close the switch of the electric control cabinet, start each DC power supply and pump station, and connect the air source.

    

2. After starting the machine, adjust the scissors, including unloading and installing the knife



Unloading the knife: Open the operating side frame, then use a hook wrench to loosen and remove the nuts of the upper and lower shafts, and put on the wire protection sleeve. Remove the knife ring, then remove the blade, and then wipe the knife shaft clean with a cloth.


Knife installation: In the process of installing the knife and the isolation sleeve, the knife must be wiped clean with a cloth before installing the knife, and the cutting blade must be installed first.


3. The production preparation work in the three aspects of uncoiler, main control worker and coiler is as follows


Uncoiler: the roll-up trolley returns to the saddle-the front movable support swings down to the lower limit-the uncoiler drum reduces the diameter, the pressure roller is raised to the upper limit-the front looper plate is lifted.


Main controller: Open the guide roller to the maximum limit-the front guide plate swings-the rear looper lifts the guide plate to the upper limit-replace the spacer ring according to the width of the cut strip.


Coiler: Replace the carpet of the tension table—Adjust the hydraulic pressure of the force table and the air pressure of the tension table according to the thickness of the strip—start the centering station—the rear guide plate is lifted—the diameter of the coiler drum is reduced, and the push plate returns to After the limit, the pressure roller is raised to the upper limit-the rear movable support swings down to the lower limit-the unloading trolley returns to the operating side-the pinch roller is raised.


    

4. Wear the belt


Uncoiler: hoist the produced coil to the saddle-lift the strip to the center line of the slitting machine-the front movable support support, the trolley is lowered, the diameter of the reel is expanded, the pressure roller is pressed down-the strip is manually pressed Passing to the force guide roller-for centering, so that the cutting edge can cut the leading edge-after the strip passes through the disc shear, the looper guide plate swings down, and the punching is carried out.


Main controller: Jog the forward transmission of the decoiler and the disc cutter to make the strip reach the tension table-Jog to make the strip pass through the hydraulic shear and press down the pressure roller-Cooperate with the coiler to pass the strip to the coiler. Diameter expansion—put down the front guide plate and the rear looper guide, and press the looper backward.


Coiler: When the master controller sends the strip to the pinch roller, press down the pinch roller to clamp the strip—with the cooperation of the master controller, send the strip head into the coiler jaw and expand the diameter— The rear guide plate swings down, and the rear movable support swings up-the centering system is driven to the automatic centering-the tension table pressing roller is pressed down-the coiler will press the strip coil 3 to 5 times, the tension table and the force table are pressed down The pinch roller is raised.
