Familiarity with guillotine scissors and its mechanism

To start working with guillotine scissors, it is necessary to turn it on first. By starting the electric motor, due to the pressure on the clutch pedal, the device starts working. The intermediates transfer the power of the electromotor to the crank or cam and cause the rotational movement of the device to be converted to vertical movement. In this way, the guillotine drawer on which the upper blade of the scissors is installed is pulled down and with the help of The lower blade is used for cutting. A series of holders are installed on the movable drawer of the machine to prevent the steel sheet from moving during cutting. In other words, these holders hold the sheet at the same time as the upper blade moves towards the lower blade. A separate piston is considered for the guillotine holders, which uses compressed air or oil under pressure to divide the act of holding the sheet along its entire length.

The components of both types of mechanical and hydraulic guillotine shears are largely similar to each other. Their main difference is in their motives. The most important components of guillotine scissors are: body blade the keeper Engine Clutch

The body is known as the most important part of any device. Rolled steel sheets can be used to make the body of this device. These sheets are first machined and finally assembled with the help of welding or bolts. They can also be made from cast parts. In addition, the combination of both methods can also be used. The body of the guillotine scissors must be very strong so that it can withstand the loads applied to the scissors, which are mainly deflection or moving loads and cause torsional stresses. Also, the scissors table must have sufficient resistance against the applied forces. At the moment of cutting, they use spring and pneumatic balancers in normal and large guillotines, respectively, due to heavy blows on the body of the scissors.

The motor is known as one of the most important performance of guillotine scissors, which causes power generation in the system. In order not to put too much pressure on the engine in continuous work and at high speeds, the guillotine engine should be considered stronger than its capacity.

The guillotine clutch is responsible for communicating and stopping rotational movements. This part of the machine starts the rotation of the crank and stops the cutting action. The clutch mechanism is the same in mechanical and friction guillotines. There are two types of clutches, mechanical and disc.

The sheet holders are installed in the guillotine scissors in order to better perform the cutting operation, hold the sheets and adjust it precisely. In other words, the holders help the sheet to remain stable during cutting. The movement of the holders causes the cutting to not be done correctly.
