LIHAO Manual Expansion Uncoiler Metal Sheet Straightener Material Decoiler Coil Steel Plate Leveler Stamping Press Machine Long GO-300

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.

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.

Frame part

1. The equipment adopts the integrated design of decoiler and straightener, to improve the utilization rate of the site.

2. Decoiler adopt cantilever beam design, all plates of the decoiler are cut by laser plasma with high precision.

3. All parts are processed by numerical control and CNC, with good interchangeability.

4. The overall structure is simple, it is convenient for general technical workers to assemble and replace, can greatly reduces the maintenance cost.
