Step 1
6.1.1 Guillotine:
Answer
The guillotine consists of a bottom cutting blade that is fixed horizontally, with a top cutting blade moving downwards. It is driven by an electric motor, utilizing a flywheel, gearbox, and axle powered by eccentric motion or hydraulic action. The machine is activated manually by foot or with lever action, allowing for precise cutting of materials.
Step 2
6.1.2 Bending rolls:
Answer
Bending rolls are equipped with two fixed rollers that rotate in unison (either manually or electrically). These rollers are designed to shape metal sheets by applying downward pressure through an adjustable third roller situated between the two fixed rollers. This pressure causes the metal to deflect, enabling it to take on the desired round shape.

6.3 What is the press machine used for in the mechanical workshop?
Answer
In the mechanical workshop, the press machine is used for installing or removing components on mechanical devices or machines. It is specifically utilized to press profiles onto material, facilitating various fabrication tasks.
