  • Why has the domestic reducer been unable to develop

    introduction:1、Price threshold At present, there are many large and small domestic reducer manufacturers,The products produced vary in quality,Also mainly in the low-end products,There is no uniform standard for the performance of products。Possession of normality、There are still few large companies with core technologies。In this way,With the increasing transparency of the market,If you cant break through the technical barrier,The price war has become one of the main means of competition in the domestic reducer industry for a long time。 In the fierce market competition in recent years,It is not difficult to find that a lot of changes have taken place in the marketing channels of the reducer,dealer、Agents are slowly fading out of the market。A lot of

  • Method for bringing in data points in CATIA

    introduction: catiaData points can be brought in as a point cloud,However, the surface sheet formed by the point cloud cannot be clipped、equidistance、Thickening and other treatments。If you just want to use a point cloud,Then the point cloud forms a point cloud surface sheet,Then a curve is formed by intersecting the reference plane with the point cloud surface,The curve cannot proceed at this timelofthandle,So lets find the curve at a given point on this curve,This is the curve that can be carried outloftisotreatment。The surface obtained by this method has a certain error。We can exchange this approach。 point

  • Introduction to mechanical properties of steel

    introduction:1、Yield point(σs) When a steel or specimen is stretched,When stress exceeds the elastic limit,Even though the stress is no longer increasing,However, obvious plastic deformation of steel or sample still occurs,This phenomenon is called surrender,The minimum stress value of yielding phenomenon is the yield point。 setPsYield pointsExternal force at,FoIs the sectional area of the sample,Yield pointσs=Ps/Fo(MPa),MPaIts called megapascalsN(Newton)/mm2,(MPa=106Pa,Pa:PASCAL=N/m2)。 2、Yield strength(σ0.2)

  • Working principle, use method and management of super clean table

    introduction:The advantage of the super clean table is that it is easy to operate,More comfortable,High work efficiency,Short lead time,Power on10It can be operated in more than minutes,Basically ready to use。In factory production,A lot of vaccination work,When you need to work often and for long periods of time,A super clean table is an ideal device。The super clean table is powered by a three-phase motor,power145~260Waround,Air is passed through layers of specially made microcellular foam sheets“Super filter”Then blow it out,The formation of continuous dust-free and sterile ultra-clean air laminar flow,Be called“Special air”,It removes greater than0.3μmThe dust of、

  • MOLDFLOW assisted mold design

    introduction:The order received by the mold factory is different from that of the general company,The orders we receive for molds are of all kinds,After all, engineers sometimes have limited experience,So with the help ofMOLDFLOWSoftware analysis function,It helps us a lot in designing molds。 Case 1,CLIPdesign: This product is a fixedUDisk retractable clip。As shown in the following picture,The deformation requirement at the mark is strict,The deformation of products produced in the past is often too large here, Our engineers consider setting the predeformation in one direction at the time of mold design,And product deformation cancel each other,To ensure that the product meets the requirements。

  • Reducer development trend and inspection maintenance skills

    introduction:Reducer inspection and maintenance Different lubricating oils are prohibited from mixing with each other。Oil level plug、The location of the drain plug and ventilator is determined by the installation position。Their relevant positions can be determined by referring to the installation position diagram of the reducer。Check the oil level Cut off the power,Protection against electric shock!Wait for the reducer to cool! Remove the oil level plug to check if the oil is full。 Install the oil level plug。 Reducer design program one、Design raw materials and data1、Type of prime mover、specification、Rotational speed、power(Or torque)、Starting characteristic、Short-time overload capacity、Moment of inertia, etc。2、Type of working machine、specification、use、Rotational speed、
