Magnetic roller and magnetic version ( die cutting machine knife version) Main principle of the magnetic fields, to arrange a single permanent magnetic iron according to the polarity, mounted on stainless steel roll groove of matrix, and due to excellent polarity distribution generate strong magnetic field and magnetic force, magnetic roller using magnetic suction die cutting machine knife version of adsorption on the surface of roll body.
the characteristics and application of magnetic die-cutting technology
usually magnetic roller protection ring ( Roll shoulder) And calibration matrix for stainless steel ring. After carburizing and hardening treatment can prolong its service life. Due to the magnetic roll used for mother roll, so the machining accuracy is higher, usually require concentricity error is not more than plus or minus 2 microns. Roll the shoulders to the surface of the roller body spacing is an important parameter, according to the product ( Mainly the thickness) To determine, with more in Europe is 0. 48mm。

die cutting machine knife version of using chemical etching method and mechanical engraving method as. First of all, using the chemical etching method. Will use the computer typesetting after die cutting machine knife version of the concave part of corrosion to a certain depth, based on the reuse of CNC machining center to machining of die cutting machine knife version, then according to the needs of small states process after processing, such as nickel plating. Chrome plated, carburizing and laser processing, etc.

the die-cutting J knife version of mainly have three basic parameters: a die cutting Angle, high knife s h and base plate thickness. A range of options for die cutting machine Angle of 30 ° ~ 120 °, usually according to the type of die cutting materials, in general, if the paper for die cutting materials, die cutting machine knife version should select a larger die cutting Angle; If the machining of the die cutting machine knife version to die cutting thin film materials and composite materials, should choose a knife high h smaller die cutting machine Angle range of options in 0. 30mm~ 1.50 mm, high specific knife to determine according to the thickness of the die cutting machine materials, 0 in Europe. 44 mm knife with more high. Plate thickness determined by knife high h s, high on his sword to 0. Under the condition of the 44 mm. The thickness of the base plate s is in commonly 0. 12mm~ 0.14 mm between.

die cutting machine knife version according to the machining process can be divided into general type, reinforced ( Hardening treatment) And laser (Make) Model, using a laser to make the die cutting knife version of the knife line up to a maximum of rockwell hardness (67 ~ 68 HRC67~68)

there are many factors that can affect the service life of the die cutting tool, such as die-cutting pressure, material type, texture, die-cutting requirements ( Half cut through or full cut through) , printing ink, machine debugging status and operation personnel, etc. So it is difficult to give an exact value. General-purpose die-cutting knife version of life in a half cut through condition generally is 200000 ~ 500000 RPM, enhanced the service life of die cutting knife version than general-purpose die-cutting knife version of 40% ~ 50%, laser ( Make) Type the service life of die cutting machine knife version than general-purpose die-cutting knife version of 80% ~ 100%.
Project Display hydraulic cutting machine, as the name suggests, find extensive use in hydraulic cutting machine institutions. Since hydraulic cutting machine has become much dependent on technology in today's world, there is wide use of such Project Display.
Zhongshan Dalilu Precision Machinery Co.,Ltd. looks forward for the meeting and the association with your esteemed company.
Long gone are those days when hydraulic cutting machine were used to hydraulic cutting machine. Now new like hydraulic cutting machine Project Display have come up.
