Machine Technical Specifications

Item	Conditions and Operating Parameters of Machine	Value
1	Operating mode of the line	setup / automatic
2	Productivity taking into account rolling and stamping, but without considering the cutting of the profile to a size	of 8-10 meters per minute
3	Voltage of the power supply network at a frequency of 50 Hz ± 0.4 Hz	3 phases, 380 V

Technical Description of Completeness:

Rolling mill
2.1	Device for threading and guiding the strip Execution example see Fig. 4.	With a roller knife, mechanical.
2.2	Profiling method Execution example see.	“Sequential profiling method,” starting with the central corrugation, then two adjacent ones, then another two adjacent ones, and so on to the end.
2.3	Number of stands Shaft diameter: 80mm	16 roller station separated molding rolling forming
2.4	Frame Execution example see	The surface of the frame must be milled and drilled with holes for mounting the stations. Milling and drilling must be performed on a milling center.
2.5	Stations (shaft supports) Execution example see	Must be made of steel, with high precision and ensure assembly and installation on the frame, without welding. Must have anti-corrosion coating.
2.6	Type of roller mounting Execution example see	On a key, through spacers.
2.7	Installed power	Two servo motors, 5.5 + 5.5 kW.
2.8	Material of rollers steel	40Х or #45, surface hard chroming
2.9	Roller knife at the beginning of the rolling mill	Mechanical (knife movement by hand)
2.9	Torque transmission Implementation example	Two loops of chain, with tensioners.
2.10	Emergency Stop Cable	around the perimeter of the rolling mill

Motor shearing or manual cutter

Servo motor

Press and guillotine
3.1	Drive type	Hydraulic
3.2	Automatic emulsion injection system	Nozzles, drive power 1 kW.
The metal tile profile production technology includes the mandatory injection of emulsion, which allows for stable quality and increases the service life of the tool.
3.3	Guillotine	Direct cut
3.4	Active type guillotine	yes, Implementation example Fig.
The active type guillotine provides two positions for the lower blade: working and initial. In the working position, the lower blade of the guillotine is raised before cutting the final profile and returns to the initial position during the operation of the rolling mill. This eliminates prohibited lengths of the finished profile and allows for the production of metal tiles with a wave length of 350 and 400 mm.

With the oiling spraying and it also can reduce the damage of the surface of the coil.

Hydraulic System
4.1	Power of the main drive	11 kW
4.2	Power of the cooling system	1.5 kW, cooling circuit with radiator and fan
4.3	Tank volume	300 liters
4.4	Working pressure in the system	12 MPa
4.5	Hydraulic accumulator	Yes
Receiving table. Implementation example
5.1	Type	stacker
5.2	Length of the finished product	1 – 6 m
5.3	Installed power	1.1 kW
5.4	Platform load, no more than	500 kg one meter
5.5	Stack height	no more than 350 mm, including the height of the pallet.
5.6	Direction of the platform rollout	forward
Automatic Control System
6.1	Controlled parameters:	– rolling speed; – count-length of products; – adjustment of pauses in the technological cycle; – production task; – program for choosing the length of the “steps”.

Type of tensioners.

Active type of stamp. The lower part of the stamp is at the starting level of stamping. Two hydraulic cylinders press from the bottom with a force of approximately 20 bar. When the upper part of the stamp descends, it does so using hydraulic plungers, which press with a force of approximately 100 bar. The upper part of the stamp presses the metal against the lower part and, overcoming its resistance, presses the metal and the lower part of the stamp to the required depth. After that, the upper part of the stamp rises, the movement of the metal begins, and at this moment, the lower part of the stamp is lifted using hydraulic cylinders. Then the cycle repeats.

View of the active die at work, in raised and lowered position.

Adjustment of stamping depth. The depth is adjusted with the help of a 6 mm thick metal plate, which is slid under or out from the lower part of the stamp. The operation is done manually, by turning the handwheel.

View of the mechanism for adjusting stamping depth.

Green arrows indicate how the metal sheet should fall. This means that after the cut, nothing should prevent the sheet from falling down onto the pallet.

The design of the shears should not hinder the finished sheet from falling down. This will allow the client to use a simple receiving table without a conveyor belt.

Active type cross-cutting shears. During stamp operation, the lower blade is in the down position and removed from the cutting area to prevent deformation of the metal around the blade during stamping. When it is necessary to make a cut, the lower blade is raised and fixed at the required level. The upper blade then makes the cut, after which the lower blade is lowered again. The cycle then repeats.

The location of the mold stamping mechanism and the metal cutting shears should be separate, but should be located as close to each other as possible.

The hydraulic station should have a capacity of 300 liters, power of 11 kW. It should have an active cooling circuit with a radiator and fan, power 1.1 kW.
