Abstract: A method and a device for producing an outer pipe of a telescope-like support, for reasons of weight and stability, is produced from a standardized zinc-coated steel pipe having a large outer diameter and a small wall thickness. Also included is the telescope-like support and the outer pipe which is contained therein. A pipe portion of the outer pipe is expanded in the method with a punch and subsequently tapered to the original outer diameter again with a ring. A reinforcement of the pipe portion and a calibration of the outer diameter of the pipe portion are thereby achieved. An outer thread can be rolled on the pipe portion.

Abstract: A method for producing a holder in which sagging is suppressed in a bent part to be formed into a flange portion, without using bulge forming and a split mold that restrains the inside of a working target article; and a holder. An upper punch presses and bends one end portion of a working target article inward, whereby a flange portion is formed in the one end portion. A smaller-diameter portion of the working target article is restrained from the inside and outside by a lower punch and split mold portions. Then, a peripheral surface portion of a convex portion of the upper punch receives the end portion of the working target article and applies an outward pressure to the end portion. A bent part is pushed toward a larger-diameter portion restraining part of a split die, so that sagging is prevented from occurring in the bent part.

Abstract: A folded tube for a heat exchanger is disclosed. The tube includes first and second ends for connection to first and second headers of the heat exchanger. An outer wall of the tube provides at least two channels for carrying a heat exchange fluid between the first and second headers. At least one seam is formed in the outer wall extending the length of the tube, the seam including a pair of opposed flanges extending into the tube to form the two channels, the outer wall joined together along the seam. The tube further includes a first end region and a second end region, and an intermediate region. The tube flattened along its length to form at least two flattened lobes, each lobe including one of the channels, and the lobes in the intermediate region being flatter than the lobes in at least one of the end regions.

Abstract: The invention relates to a method and stretch-bending straightener for straightening metal strips (1) by stretch-bending, comprising a plurality of straightening rolls (5a, 6a, 7a, 8a) which are arranged behind one another in the strip flow direction (D) and spaced from one another in the strip flow direction (D), wherein the strip (1) subject to tensile stress below the limit of elasticity is alternately bent around the straightening rolls (5a, 6a, 7a, 8a), undergoing plastic elongation, wherein a deflecting roll (5b, 6b, 7b) is arranged upstream of one or more straightening rolls (5a, 6a, 7a), respectively, wherein said straightening rolls can be adjusted relative to the strip (1) and wherein said deflecting roll has a larger diameter than the respective downstream straightening roll. Said method and said system are characterized in that, in order to vary the immersion depth, the straightening rolls (5a, 6a, 7a) can be adjusted relative to the associated deflecting roll (5b, 6b, 7a) such that the free strip length (F) between the run-off point (9) of the strip (1) from the deflecting roll to the run-on point (10) of the strip (1) onto the associated straightening roll does not exceed a predefined maximum value, above which longitudinal undulations of the strip form. The system is preferably designed such that, as the immersion depth and/or the angle of contact are varied, the free strip length never exceeds the maximum value over the entire adjusting range.

Abstract translation: 本发明涉及一种用于通过拉伸弯曲矫直金属带（1）的方法和拉伸弯曲矫直机，包括在带材流动方向上彼此相对布置的多个矫直辊（5a，6a，7a，8a） D）并且在带材流动方向（D）上彼此间隔开，其中经受低于弹性极限的拉伸应力的条带（1）在经过塑料的矫正辊（5a，6a，7a，8a）周围交替弯曲 伸长率，其中偏转辊（5b，6b，7b）分别布置在一个或多个矫直辊（5a，6a，7a）的上游，其中所述矫直辊可以相对于条带（1）进行调节，并且其中所述偏转 辊具有比相应的下游矫直辊更大的直径。 所述方法和所述系统的特征在于，为了改变浸入深度，可以相对于相关联的偏转辊（5b，6b，7a）调整矫直辊（5a，6a，7a），使得自由条长度 在条带（1）的偏转点（9）从偏转辊到条带（1）的接触点（10）到相关联的矫直辊之间的距离（F）不超过预定的最大值， 在其上方形成带的纵向起伏。 该系统优选地被设计成使得随着浸入深度和/或接触角度的变化，自由条长度在整个调整范围内不会超过最大值。
