| Cause analysis of damage of pipe bender bit
In order to better save resources, low cost, then it is necessary to choose a good pipe bender.Why do you say that?In general, the drill bit is the most common and fastest processing product in pipe bending. In order to save resources and reduce costs, a good pipe bender should be selected.Why do you say that?In general, the bit is the most common and fastest processed product in pipe bending. Why does the intermediate frequency pipe bender wear the bit so quickly during pipe bending? Let's explain in detail.Drilling,, including chemical PCB composite material friction and wear.Drilling, including the friction and wear of chemical PCB composite materials.Due to the chemical penetration of the analysis of product circuit board drilling carbide materials co., LTD. WC - cobalt bonding chemical decay.At 300℃, the reaction is significant.Although drilling rates are lower than 150 mm/min, chemical wear is no longer worn in important situations, and friction and wear become important manifestations of wear.PCB penetration and micro cutting rates, elbow radius of drilling and width ratio of fiber bundles.Study on the ratio of the width of the fiber bundle (fiberglass) of the drilling radius, the proportion of the tool cutting things, the fiber width and the tool wear.In practical application, new drilling 2500 grinding, grinding drilling friction, second grinding machine drilling machine to 1500 to three grinding drilling grinding, PCB microhole process, axial force and torque as feeding and drilling depth growth, important cause and chip removal position place.The increase in depth, drilling, chip removal difficulties, disposal in this environment penalty of bending, cutting, resin material melting temperature and rigid will be glass fiber, aluminum, binder fragments of cutting.The arduous cutting and PCB matrix material has an affinity, once such a cut is produced, and then stop chip removal, axial force and torque rapid growth, resulting in drilling fractures of microholes.PCB microporous fracture, rotation pressure zigzag and rotation pressure curve, which is above the two fracture coexist.The fracture mechanism is important because they are busy reducing the critical factor of increased drilling torque when the obstruction is blocked.Axial force, which reduces cutting torque, is the key to reducing trivial pores.This increases the wear of the bending bit.
Knowledge of the use of the pipe bender and how the pipe bender works
Pipe bender machine tool equipment in the mould, we often need to mention, there are winding mandrel and no new twists and turns, the two without winding mandrel pipe bender is much more roughly, usually in carbon steel pipe bender, half of big diameter, tube wall is thick and some other would be common galvanized pipe, our pipe bender is accepted without mandrel twists and turns, mold production capital is also low, skill is not so difficult.But the mandrel twists and turns are relatively difficult skills will be a lot higher, especially when we use our pipe processing machine tools, accept the bending machine mold with mandrel and wrinkle prevention mold, and so on, in the mold debugging will be a lot more difficult.
The pipe bender can not only bend the small radius pipe, but also simmer the large diameter steel pipe, and simmer the radial steel pipe, square steel pipe, Angle steel pipe, channel steel, I-beam and other profiles.It's used for building Bridges and other industries.The pipe bender accepts continuous heating without interruption throughout the whole process, including the high precision, correct bending radius and low ellipticity of the steel pipe section. It is one of the pipe bending equipment that is not available or missing in the current industry.
Pipe bender and cold pipe bender each have their own advantages and disadvantages. Pipe bender is important for the production of large diameter and large wall thickness pipe, while cold pipe bender is important for the bending of small diameter and small wall thickness steel pipe.
