III,Equipment structure description

• Coil storage rack

Purpose: to store steel coils to be opened.

Structure: v-shaped structure, steel plate welding, two bolts fixed on both sides of roadway.

Technical specification:

• Coil car

Purpose: to transport the coil material to the uncoiling machine.

Structure: the car is installed in the roadway below the floor, which is mainly composed of the vehicle seat and traveling wheel shaft, v-shaped material frame and guide bar, traveling deceleration motor and lifting oil cylinder.

Technical specification:

V-shaped bracket is welded by steel plate, and nylon plate is laid on the surface

Motor AC4KW

Lifting oil cylinder Ø200X850st

Guide bar number four, Ø 110 mm diameter, chrome plated

One protective chain and one pair of rail

• Uncoiler

Use: support raw steel coil.

Structure: double support type.By the expansion and contraction of the drum, transmission box, transmission mechanism, pneumatic drum brake, roller on the middle slide.When the belt is worn, the motor opens the material head actively. When the production line is working continuously, the output shaft of the decelerating motor disengages through the clutch, and the motor does not work. The coil material is driven by the traction straightener or slitting machine.The uncoiling tension is provided by the drum brake.

Technical specification:

Drum three steps, increases range of respectively Φ 470-520 mm, Φ 570-620 - mm , Φ 720-760 - mm.

Increases and oil cylinder specifications Ø 150 x100mm, 2pcs.

• Pressure leading device

Purpose: to shovel out the bent material head and introduce it into the traction straightening machine.

it is composed of roller, roller and plate.Bending roll coating, hydraulic pressure to tighten the roll material head, electric rotation of the exhibition of materials;The shovel head supports the plate with night pressure expansion and hydraulic swing, and the plate head is drawn out by aligning the material head;The bending roll is pushed by the oil cylinder and matched with the support plate of the shovel head to press the plate head straight so as to facilitate the material head to expand into the traction flatting machine.

•  Slitter machine( double knives base type)

Usage: to cut the sheet material lengthways into various widths

Structure: slider type.By the two sides of the tool, upper and lower shaft, shaft spacing adjustment mechanism, transmission device and so on.Dc motor drives the tool shaft rotation through reducer, gear box and universal coupling, and the motor drives the side tool rest to open and close for convenient tool change.Include quick change knife device .

Technical specification:

Purpose: guide strip separation

Structure: there are two groups of separators, which can be moved out horizontally to replace isolation plates. The hydraulic pressure roll is installed between the two groups of separators to prevent the slats from jumping out of the isolation plate

•  3-roll tension burr extruding machine

Purpose: to add tension and squeeze burrs

Structure:

Usage: the steering roller is installed between the tension station and the rewinding drum to form the Angle of rewinding and wrapping.

Structure: the steering roller is chromium-plated on the surface, and the end part is equipped with speed gauge plate.The supporting plate is raised and dropped by the cylinder. The surface of the supporting plate is chrome plated

• Recoiler

Usage: rewind the material after slitting.

Structure: the roller is composed of main shaft, wedge slide block, pull rod, clamp mouth and arc plate.The drum is driven by dc speed regulating motor, the cylinder drives radial expansion and contraction, and the arc plate has clamping jaws.The hydraulic tape separator on the reel can automatically rise with the increase of the steel

coil.With pneumatic brake device.With hydraulic push plate, auxiliary unloading.The rear side of the drum is equipped with hydraulic auxiliary material pressing plate and auxiliary material pressing head.

• Recoiler support

Purpose: to support the cantilever end of the reel to increase its rotation rigidity under load.

Structure: closed door structure, the conical hole set on the cylinder driving support on the uncoiling conical support roller.

• Unloading car

Usage: remove the slitting coil material from the reel drum of the winder

Structure: the car is installed in the roadway below the floor, which is mainly composed of the car seat and walking wheel shaft, idler and guide bar, walking speed reduction motor and lifting oil cylinder.With anti-inverted rod.
