Q:How to adjust the clearance between the upper and lower blades of the slitting machine?

Method for adjusting installation clearance between upper and lower rolling blades of slitting machine:The clearance between the upper and lower blades of the slitting machine is usually adjusted by precision shims. But be careful, if the blade concentricity or balance is not good, then you have to sharpen the knife again.Slitting machine and slitting line, slitting machine, slitting machine, is a kind of metal cutting equipment. 1. uses: suitable for longitudinal shearing of metal strip, and winding the slitting strip into coils. 2. advantages: easy to operate, high cutting quality, high utilization of materials, cutting speed, stepless speed regulation and so on. 3. structure: from uncoiling (unwinding), material positioning, slitting, slitting, coiling (winding) and so on. 4. applicable materials: tinplate, silicon steel sheet, aluminum strip, copper, stainless steel plate, galvanized sheet, etc.. 5. applicable industries: transformers, motors, household appliances, automobiles, building materials, packaging industry, etc..

Q:Hob mainly used for processing what?

Cut into strips evenly

Q:Din 5480 8j precision involute spline with what grade of hob processing?

The accuracy of the drawing gear determines the hob grade, which is basically the same as the national standard. You can also see the West Germany 5480 standards.

Q:What are the main causes of hob breaking?

In my opinion, there are many reasons for the broken teeth of the hob. In addition to the above analysis, it is also related to the regrinding of the tool, such as grinding the front face of the knife and grinding cracks

Q:When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?

Pressure angle, vortex data can be calculated, Wenling Kaisheng machinery specialized hob, broach, milling cutter, gear machining

Q:Does the forum superiors in the gear hobbing process, because the workpiece in addition to generating motion, and an attachment movement for generating helical gear so I want to ask the question is to spur gear hob, turning a lead, the workpiece will rotate (360* / gear hob the number of degrees) for helical gear hob the same rotation of a lead, because of the additional movement of the workpiece, the workpiece rotation degree will be how much? PS: suppose the hob is the same as the gear rotation

Mainly according to the size of the spiral angle and material hardness, feed speed, this is not to say, high speed, feed volume is relatively small, more than 25 degrees or slow down a little better

Q:Experts, EG, how much is the hobbing hob used in the actual production of engagement? Feed rate? What is the effect of spindle speed, machining accuracy? What is the M2 M2.5 M3 M3.5 M4 M5 / M6 M7 M8 M9 M10 engagement, the lathe is Chongqing 3180 thank you teachers, generous with your criticism

Feed standard gear is 2.25* modulus relationship of gear spindle speed and machining, Y3180 hobbing machine workbench is the maximum speed of not more than 5 minutes per turn, speed is too fast, the worm attached table soon wear out.

Q:Hello everyone！ I would like to ask about the difference between variable displacement hob and non variable hob First of all, is there any difference between the non - variable and modified gears in the design of hobs? If it's different, please give me more details, thank you!

The design modulus of the shift gear hob is different from the product modulus!

Q:What is the number of hob head?

What is a single head hob? What is the number of hob heads: the number of heads (the head number or the number of teeth in the same law)Roll vortex due to vortex with a single head, double head, three head, it should also have the corresponding hob single head, double head, three points, often double or three units lack of hob can only use single head instead, how may be close to the workpiece in drawings is a technology problem.What is the fixed number: the amount of the call is only the quantitative numberIn hobbing adjustment, need to compute three gears, namely indexing hanging round I, feed, hanging wheel i: and differential gear i:. formula i_1=A_1 - Z_1/ (Z+ Z)...... (1) i_2=A_2 & f...... (2) i_3= (n - A_3 (+) /Z_1 (| Delta Z|) + /f (sin beta) / (n - m_n))...... (3) in the formula: A_1 - rolling gear machine indexing set number; A_2 rolled into a given number of gear machine; A_3 hobbing machine differential number; F hob vertical feed amount (mm/r); Z_1 - hob; Z - gear tooth number; Z supplement (micro workpiece tooth number the number of teeth), | Delta Z|

Q:What do you think about the cutting hob?

The thin one becomes thin Mostly uniform, and don't cut it.
