The method of forming a square tube, curved real solid bend, suggests that it is compacted bent inside and outside the real-bending roller and tube outer wall two-way compaction. 1) The real advantage is that the rebound small bend, forming accurate, precise and long roll, molded interior angle R more accurate. 2) there is a drawback of real bend stretching / thinning effects. First, a solid curve bends will produce a draw effect of the longitudinal length of the bend lines shortened; second, real curved bend in the metal due to stretching and thinning. 2, the air bend moment the air bend formed by the one-way contact with the outer roller and the outer wall of the tube so that the strip is bent, the air bend bending line will produce compression, bend lines longitudinally elongated effect make non-standard square tube 35 * 45, bending occurs at the metal accumulation thicker non-standard square tube 35 * 60, which is compressed air bend / thickening effect. 1) The advantage is that it can be air bend side bend in real time can not be bent, such as square and rectangular tube top / side synchronous bending and finishing. Air bend can also bend R <0.2t inside corners without wall fracture. Disadvantages 2) is in the upper air bend / air bend when synchronization sides, since the upper and lower rollers while producing pressure forming force easily beyond the critical point, resulting in instability of the concave edge portion, and can also affect the stable operation of the unit and molding quality. This is also the moment when pipe and tube side air bend forming different characteristics. The strength of the mechanical properties of the pipe is defined Q195 welded square tube under the action of the information payload to resist destruction (right amount of plastic deformation or fracture) function. Because the role of a stretch in the form of load, tight, winding, cutting, etc., because the intensity is divided into tensile strength, compressive strength, flexural strength, shear strength. Among various strength will certainly contact often use more normal to tensile strength as the most fundamental hands. Function Index [1] Q195 welded square tube analysis - strength with great progress on the action to load parts called strikes load, Q195 welded square tube is under load boycott strikes to destroy the power of the so-called strikes toughness. Function Index [2] Q195 welded square tube - A discussion behind the strikes toughness strength, ductility and angle are metal machine functions are still under the hands of the load is applied. The practice of non-standard square tube 38 * 50, many mechanical machine load hire services are being repeated, is that the whole environment will be tired occur. [3] Function Index Analysis square tube welded Q195 - Q195 tired rarely used method of welding angle square tube Brinell (HB), Rockwell angle (HRA, HRB, HRC) and Vickers angle (HV) and other methods. Angle is a measure of the level of the hands of hard and soft metal materials. Lifetime angle in front of the default method is the most rarely used method is pressed into the angle, it is surely the geometric shape of the indenter is surely under load is pressed into the surface of the metal materials to be tested, according to the default level is pressed into the angle value. Function Index [4] Q195 square tube welded Analysis - Plastic angle Q195 refers welded square tube under the information load, the occurrence of plastic deformation (never deformation) without destroying power. Function Index [5] Q195 welded square tube - A mechanical features plastic square tube.
