Q:What does "hob" mean when cooking?
Correction: hob shall be hob block.Main points of hob block operation:The raw material is hob block roll up into pieces, to cut hob block must grasp three points; one is straight knife, two is the raw material and the knife angle between 45 to 60 degrees (about 70, three dollars is scissors) is every slice have to scroll a raw material, the rolling amplitude is determined you want to process massive size, is generally 1/3 weeks rolling material.Block cutting method of hob:1, a first bevel knife.2. Turn the section face up.3, in the 1/2 section (according to the block size and decided to cut the oblique).4, and then the last section of the plane turned upward.5, or about 1/2 oblique. This keeps turning over everything and turning everything over.
Q:What is the reason that the double gear hob changes the gear line of public gear too big?
Scraping the general process, scraping hob hob - modulation ---- carbide hob scraping. The general amount of stay, such as M5, usually leaves about 0.4. However, alloy hob is more valuable. Scraping hob must have roots, otherwise easily jump alloy hob tooth. Just say that.
Q:Known gear hobbing machine speed, knife, and hob modulus, the number of teeth of the workpiece, the processing thickness (Chi Kuan), how to calculate the processing hours?
It is very difficult, not numerical control, ordinary hobbing machine can only work experience, feel how much time a workpiece processing
Q:What is the stress on the disc cutter in general shield machine?
Different strata use different types of hobs, and the rock breaking ability is the most natural rock shield machine
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:The influence of hob accuracy grade on gear machining
It has something to do with smoothness! If shaving, the hobbing machine B will be enough! When we do not shave teeth, with double A knife shaving, then the series of knives will not affect too much
Q:What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?
There are pictures and documents in the attachment, and the processing methods and principles of each tool are explained
Q:How about the front edge, the normal and the normal tooth shape of the hob with rake angle?
Generally speaking, the front rake or the negative rake of the hob, the slot is straight. If the spiral groove hob, then the front face of the eccentric distance can not be controlled, the front and left side of the tooth shape can not be measured using the front face of the intuitive measurement method, there will be no knife surface measurement method is inevitable. If you really need, you can use the following formula Tan = w (Tan an*cos af+-sin AF *sin WF /cos WF) this formula can be converted into the reference tooth angle parameters of front blade tooth angle formula in meaning, can I see the previously available analytical formula
Q:What grinding wheel do we use to grind HSS HSS hobs?
You can choose PA or SA grinding wheel, particle size 46-60#, hardness J-K, you can.
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.
