Automatic sheet metal uncoiling and straightener machine

Automatic sheet metal uncoiling and straightener machine

Description :

Feature

1.    All rollers with drive function.

2.    The upper work rollers adopt 4 point fine micro adjusters with 0.01mm advance reference indicators. High quality precision.

3.    All roller materials adopt bearing steel, high frequency thermal treatment to HRC 60°, hard-chrome plated and ground finished.

4.    Japanese bearings—high precision and durable.

5.    Leveler inclines appropriately to reduce feeding loop distance.

6.    Compatible with other feeders.

Machine structures:

·Straightener head

1. Adopt parallel roller design, 3 up / 4 down, totally 7 rollers.

2. Adopt four point fine adjustment is adopted, which is more suitable for processing high-precision products. Adopt four point independent pressure to adjust the pressure of feeding roller for entrance and exit, which can prevent material deviation and deformation effectively.

3. The supporting roller adopts the galvanizing roller without power, the material is one body formed, the surface is scratch-resistant and wear-resistant, use the mechanical bearing, rotating flexible and durable.

4. Handwheel made of cast iron, surface is electroplated. It is the most traditional handwheel.

5. The transmission part is protected by protective cover on both sides, equipped with observation window for easy viewing.

Straightening roller

1. The straightening rollers are made of solid bearing steel, thickening plating treatment after medium frequency, surface hardness is not less than HRC58, to ensure material durability.

Adopt GCr15 forging round steel, after preheating treatment (spheroidal annealing), then turning, milling, intermediate frequency treatment, rough grinding and cold stabilization, then fine grinding, finally electroplating. Maximized guarantee the accuracy, concentricity, finish and hardness, and extended the using life of the rollers

Drive gear

Gear processing includes the following processes: gear blank processing - gear surface machining - heat treatment - gear surface fine grinding. Rough parts are mainly forging parts. Through normalizing treatment, improve the machining to facilitate cutting. According to the gear design drawings, rough machining, and then semi-finishing processing, turning, rolling, gear shaping, to make the gear basically formed. After the heat treatment to improve the mechanical properties. According to the design requirements of the drawings, finally do the finishing, finishing the benchmark, finishing the tooth profile. After all above treatments, our gear grade can reach to grade 6, with high wear resistance, high strength, long using life.

Electric control box

1. Adopt silver alloy relay, full copper coil, flame retardant safety base, long lasting and durable.

2. Adopt safety protection adjustment circuit time delay relay, silver alloy contact, satisfied different delay ranges.

3. The switch adopts sliding contact ,with self-cleaning function , normally open and normally closed contact adopts separate bonding structure, can work with different poles, equipped with anti-rotation positioning and stop loose mounting gasket.

4. Adopt self-duplex flat button, the force is light, the key range is moderate, the building block type combination structure. The contact is made up of keto-base composite points with strong conductivity and large current, with a life span of up to 1 million times.

Power part

1. Adopt model 80 worm gear vertical reducer, use the speed converter of gear , reduce the rotation number of motor to desired rotation number ,and get the mechanism with larger torque.

2. Adopt vertical motor, low vibration, low noise, stator rotor part adopt pure copper coil, life is 10 times of ordinary coil, both ends are equipped with ball bearing, low friction, low temperature.
