42Crmo hardness upper press brake and bottom dies V type

Harsle supply press brake tooling including 30°and 60°upper press brake tooling,single V down tooling,Double V down tooling

The length of upper/lower tooling is 835mm. In order to bend different size sheet metal, it is being customized into below sections: 10+15+20+40+50+100+100+200+300=835

Machine tool upper tooling:

• Sharp blade: bending angle ≤ 30°, plate thickness ≤ 5mm
• Straight blade: bending angle ≥ 88° (If don’t have special requirement)
• Goose neck blade: bending angle ≥ 88°, need deep bending process

• Machine tool lower tooling:
  • Low tooling including single V and double V. The opening can be adjusted in the range of 4-80mm (that is V4, V6, V8… V40)

Steel-making by medium frequency furnace

We meet special requirements for materials . In order to guarantee the quality ,the company imported the spectrometer from Germany and is equipped with various testers,such as tensile tester,impact testing machine,metallography analyzer and so on .

Electro slag remelting

The largest ingot can reach in Harsle .The ingot obtained by this remelting/refining process is very homogeneous and free of internal defects . The segregation of the ingot (called macro-segregations ) are substantially eliminated and the segregations of crystals (called macro-segregations ) are significantly reduced .

The ESR remelted material improve following mechanical characteristics :

   Improved toughness due to increased homogeneity and isotropy

   Improved creep resistance properties

   Best fatigue strength and tenacity properties as well as outstanding tensile strength

   Improved purity

Forging steel

The largest electro-hydraulic hammer is 4.5 ton .And more than 6 skilled technicians work for us .After forging ,the inside microstructure becomes much closer and the metal grain size becomes much smaller . It can evevate the characteristics and quality of the knife ensuring a longer life .

Rough processing

No less than 40sets of processing equipment in the rough processing workshop of Harsle , including lathe ,milling machine , planer , drill machine etc. Skilled workers are employed in its rough processing workshop .

Heat treatment

Our company has independent workshop for heat treatment . Couples of skilled technicians work here . Actually , most tools ( thickness ≤100mm) can be fully hardened . Thus ,the blades can be used after repairing until the size reached the minimum design dimension .

Finishing

Harsle has more than 35 sets of processing equipment including internal grinder , external grinder , surface grinder ,CNC grinder ,electric spark CNC wire-cut etc. The company can produce the shearing blades with 5500mm in length and slitting knives with 1300mm in outside diameter .

Testing

 Various testers are put to use for testing its products in our company . They are including tensile tester , impact testing machine , metallography analyzer , harmless flaw detector , magnetic powder inspection , hardness tester , caliper rule , microcalliper , etc . Testing is carried out after each step . And every product has a unique track number . Thus it is easy to trace back anytime .

Packaging :  

 Inside packing: Applied with anti-rust oil and then packed in plastic bag

  Outside packing: Packed in plywood case
