Selection and treatment of original material of edge cutting die
Edge cutting die in the matter, its edge department by intense friction and extrusion, and by the impact of the inevitable impact, which requires the edge cutting die has a higher hardness, strength, wear resistance and better toughness, so the selection of materials is very critical.
Edge cutting die is made of Cr12MoV steel, and its function can be improved.Compared with 9SiCr steel, Cr12MoV steel has a higher carbon content and high chromium content, and the Si content is lower, so Cr12MoV steel has a high hardenability, high wear resistance, and hardness, toughness are more than ideal.Fasteners,
For 9SiCr steel and Cr12MoV steel raw material, stop casting, spheroidal annealing, and then stop machining, which can eliminate the original material's weigelsen structure, network carbide and other shortcomings, make the structure more dense, greatly improve the original structure.Especially for Cr12MoV steels, because it is high carbon high chromium steel, built of its cutting edge often because of carbides distribute uneven sign collapse edge, in use, therefore, change forging, must stop its: instead of forging process for forging billet heating temperature is 1100 ~ 1150 ℃, forging temperature is 1080 ~ 1100 ℃, the final forging temperature is 860 ~ 880 ℃, the change of carbide segregation after forging, below level should be in 2 ~ 3 still need real-time annealing after forging.Material type determines the selection and treatment of the original material of the life cutting die
Often used 302, 304 auto parts, 316, 201, 667, in the order of stainless steel rolling wire, it is necessary to inform the production of stainless steel rolling wire manufacturers you use the stainless steel material model, so that stainless steel dental plate manufacturers for the choice of common suitable material and thermal treatment process!
Mechanical functions and oils
Machinery is too old, clearance is too big to the wear of stainless steel wire board also plays a big role, mechanical function unchanged, the wear of stainless steel teeth board will be less, life will progress, oil must choose public stainless steel screw oil, good oil can reduce the consumption of machinery and wire board.
Mechanic tuned machine
Tooth plate use life and mechanic tuned machine also has a lot of contact relationship, the individual technician preferences pressed stainless steel thread rolling plate into the material end firmly, like stainless steel teeth plate earlier rod end socket head will wear out very easily, if it is a pair of tooth plate in the process of producing smoke is very big, like this pair of tooth plate use life will be very long!Proposed teeth flat, gradually pressed to the appropriate position for the best, not only can delay the use of life, but also can improve productivity.
