Do you know the reason why the stainless steel hydraulic joint is easy to be corrugated?

Stainless steel pipe processing why easy to appear corrugated?Not much to say, I believe many friends have been impatient.

In fact, the main reason why the stainless steel pipe corrugated, is due to the grinder, steel pipe, sand you know the stainless steel hydraulic joint processing easy corrugated reason?Caused by the vibration of the wheel system, or by the vibration of the grinding wheel relative to the workpiece.The vibration includes forced vibration and self - excited vibration.There are many specific reasons causing vibration, among which the main one is that the grinding wheel is not balanced and no careful balance test has been conducted before installation.Therefore, forced vibration occurs in the grinding process, which causes the surface of the stainless steel tube to appear straight wavy.Since the frequency of forced vibration is equal to the frequency of the excitation force or a multiple of it, the wave generated by yonghua hydraulic joint is deeper and wider, and the wave frequency is related to the rotation speed of the grinding wheel.Stainless steel tube processing, guangdong all types of stainless steel tee joint identification method can by a thin layer of red oil on the surface of the workpiece, and adjust the worktable movement speed, turn the workbench move distance in workpiece rotate a slightly equal to 2/3 of the width of the grinding wheel, and then move the wheel frame, make the wheel just contact red oil (not cut), longitudinal feed rapidly after the blade at a time.At this time, the trace of "polygon" can be observed on the surface of the workpiece, and the distance of the wave (i.e. the width of the edge of the polygon) can be measured, and the frequency of the wave (wave frequency) can be calculated.The identification method of surface grinding is similar.

Stainless steel pipe processing

The grinding wheel drive motor yonghua card sleeve joint is not balanced, it will also produce forced vibration and cause straight wave ripple (when grinding the outer circle) or horizontal wave (when grinding the flat surface), the situation is similar to the grinding wheel imbalance.For the same reason, the grinding wheel drive belt is of different thickness and length, and the liquid pulsation in the oil pipeline caused by the work of the oil pump in the stainless steel y-type tee of all models in guangzhou and the hydraulic transmission mechanism of the grinding machine may also appear similar forced vibration.But the resulting vibration is slightly less severe.When the surface of stainless steel tube is processed, the elastic deformation of the steel tube and the machine tool system in the grinding process will increase the intensity of self-excited vibration in the grinding process and make the surface of the steel tube appear straight wavy.At this time, the ripple is relatively shallow and dense, and the wave frequency is generally around 300 / s, which is inconsistent with the rotation speed of the grinding wheel.The less rigid the steel tube and the machine tool system, the greater the friction of the grinding wheel on the workpiece, the larger the amplitude of the self-excited vibration, and the deeper the ripple.

What is the forming method of stainless steel processing?1. Single radius forming method: there are three kinds of circumferential winding forming method, marginal winding forming method and central winding forming method.The forming of stainless steel welded pipe fang yonghua welding joint method, the strip from the horizontal roller and roller through the middle, and then the flat plate into a circular tube.

2, circumferential zigzag forming method: stainless steel processing in the direction of the width of zigzag deformation, and the zigzag radius is gradually reduced until the steel belt into a circle closed.

3. Double radius forming method: it selects more than two fundamental deformation methods for combined deformation, among which marginal forming method and circumferential forming method are commonly used in comparison.The forming method of Beijing stainless steel processing, the process of this forming method is relatively stable, huzhou whole model of stainless steel T tee and deformation is uniform, so the forming quality is good.

4, row roll forming method: stainless steel processing through the small roll installed in the cage structure to shape, mainly by the pre-bending roll, row roll equipment and finishing roll, suitable for the formation of thin wall steel pipe.

5, stainless steel processing spiral welded pipe pendulum molding method: and divided into spiral stainless steel processing before the pendulum molding and spiral stainless steel processing after the pendulum molding these two kinds, the main difference is whether the unit is equipped with looping.
