Tube Bending Processing Techniques and Methods, and How Medium-Frequency Bent Pipes are Extruded:
Tubu Liwi—Ipproċessar Tekniki u Metodi:
Tubu liwi ipproċessar huwa a metodu biex tkompli ittejjeb il - prestazzjoni vantaġġi ta ' pajpijiet wara produzzjoni. Processed pajpijiet se have an estiża ħajja u usa ' applikazzjonijiet. Hawn taħt huma dettaljati spjegazzjonijiet ta ' il it-tekniki u metodi involuti.
Tekniki:
1. Roll Bending: This method involves bending pipes using three rollers, where roller 3 is the primary roller, and the other two are secondary rollers. Bending is achieved by changing the distance between the primary and secondary rollers, allowing for various radii of curvature. It is suitable for bending rings, helical fittings, and thick-walled pipes with large curvature radii.
2. Press Bending: This method uses molds on a hydraulic press to bend steel billets. It is used to create pipes or bent pipes with straight segments, among other shapes.
3. Istralċ Liwi]3a
- Manwal Tgħawwiġ: This has a low manufacturing cost, simple equipment, and easy adjustment, making it adaptable for small-batch production.
- Bending Machine Bending: Depending on jekk a mandrel is used, it can be classified as mandrel bending or mandrelless bending.
Metodi:
1. Ittimbrar Metodu: Dan metodu użi a tapered punch on a agħfas biex tespandi il - pajp tmiem għal il meħtieġ daqs u forma.
2. Rolling Metodu: A mandrel is placed inside the tube, and the outer wheel is pushed to process rounded edges.
3. Bulging Metodu:
- Rubber Bulging: Rubber is placed inside the pipe, and the upper part is pressed using a punch, causing the pipe to protrude and take shape.
- Idrawliku Bulging: Likwidu is injettat in in il nofs ta' il-pajp*biex tespandi it f' il mixtieq forma. Dan metodu huwa komunement użat fi il produzzjoni ta ' corrugated pajpijiet.
4. Rolling Metodu: Ġeneralment użat mingħajr a mandrel u adattat għal il ġew tarf ta ' ta' ħitan ħoxnin pajpijiet.
5. Forġa Metodu: The pipe end or part is extended by a forġa machine to reduce the outer diameter of the pipe. Commonly used shapes include rotating, connecting rod, and drum types.
6. Bending Forming Method: It can be divided into stretching, ittimbring, 2c and roller methods. The final pipe is bent using 3-4 rollers, two fixed rollers, one adjustable roller, and adjustable roller spacing.
Bent pajpijiet joffru aktar funzjonalitajiet minn dritta pajpijiet dovuti għal tagħhom mgħawġa forma. Manifatturi spiss proċess differenti tipi ta ' pajpijiet biex itejbu tagħhom kwalità u jissodisfaw diversi ħtiġijiet.
Kif Frekwenza Medja Bent Pajpijiet huma Estrużi:
Estrużjoni is a iffurmar metodu, u frekwenza medja mgħawġa pajpijiet ħtieġa biex iżommu tagħhom forma wara li tkun mgħawġa. Biex tikseb dan , huma jgħaddu an estrużjoni proċess.
1. Materjal Selection: The material used for extrusion in medium-frequency bent pipes typically has a melt flow index of less than 1 and a medium to wide melt flow distribution (MWD). Using low melt index (MI) materials helps achieve the appropriate melt strength. Wider MWD grades are more suitable for extrusion għax huma offer higher production rates, lower die pressure, and reduced melt fracture tendencies.
2. Bent Plate and Thermoforming: Thermoforming is used to create linings in many large picnic coolers, li huma magħmula of polyethylene and are known for tagħhom ebusija, lightweight, and durability. Other sheet and thermoforming products include fenders, tank linings, dish shields, transport containers, and tank bodies. A rapidament growing application of sheet materials is plastic film or pool bottom villages, based on the ebusija, chemical resistance, and impermeability of MDPE.
Frekwenza medja bent pajpijiet huma essenzjalment ipproċessati minn aktar liwi standard pajpijiet. Madankollu, sempliċement liwi il-pajp is mhux biżżejjed , u xieraq estrużjoni matul il - liwi proċess itejjeb ċerti funzjonalitajiet ta ' il- pajp . Effettiv estrużjoni xogħol must be carry out matul il iffurmar proċess.
Please note that "挤塑" (jǔsù) means "extrusion" in English, which is a manufacturing process used to create objects of a fixed cross-sectional profile by forcing material through a die.
