摘要： Seamless well drill tubes are formed by extruding seamed tube blanks through a die throat by pushing the tube blank through the die throat with a pusher rod having a portion located internally of the tube and die throat. The pusher rod has a narrow lead portion so that as the lead end of the tube length is forced through the die throat, its material flows inwardly to form an inwardly thickened annulus and therefore, the remainder of the pusher rod is located within the die throat and blank so that the blank material flows into the desired wall thickness. Before the tube is completely pushed through the die throat, the pusher rod is removed and the second tube blank is inserted in end to end contact with the trailing end of the first blank. Thereafter, the pusher rod is reinserted into the tube of blanks and advanced so that the force of the pusher rod causes the second tube to push the first tube completely through the die throat while the lead end of the pusher rod is positioned within the die throat so as to form the inwardly thickened end portions on the trailing end of the first blank and the lead end of the second blank. Thereafter, the cycle is completed to successively produce drill tubes having inwardly thickened flange-like ends. These ends may be converted into outwardly extending flanges by forcing a punch into each end to flow the thickened end annulus radially outwardly.
摘要翻译：无缝钻井管是通过挤压接缝管毛坯通过模头喉部而形成的，通过用具有位于管内部和管喉部分的部分的推杆将管坯推过管颈。推杆具有窄的引导部分，使得当管长度的引导端被迫通过模具喉部时，其材料向内流动以形成向内增厚的环形空间，因此推动杆的其余部分位于模具喉部内并且坯料使得坯料流入所需的壁厚。在管被完全推动通过模具喉部之前，推动杆被移除，并且第二管坯被插入与第一坯件的尾端端对端接触。此后，将推杆重新插入坯料管并推进，使得推杆的力使第二管将第一管完全推入管颈，同时推杆的前端位于管芯喉部以便在第一坯料的后端和第二坯料的前端上形成向内增厚的端部。此后，循环完成，以连续生产具有向内增厚的凸缘状端部的钻杆。这些端部可以通过迫使冲头进入每个端部而使加厚的端部环径向向外流动而转换成向外延伸的凸缘。

摘要： A process for cold forming integral spindle-axle tubes includes placing a tubular blank within an open ended die having an extrusion die throat, and pushing the blank through the die throat with a punch. The punch is formed with a ram portion that applies pressure to the blank for moving it axially through the throat. The punch also has an extension closely fitted within the blank so that as the punch pushes the tube axially, the blank is extruded between the die throat and the extension to form a thin wall tube. After the blank is partially extruded, the punch is removed and a second blank is inserted. This second blank is then located between the punch ram portion and the trailing end of the first blank so that further movement of the punch causes the second blank to push the first blank through the die throat. At that time, a second punch extension, of smaller diameter than the first one, is arranged within the throat so that an inwardly thickened ring-like annular section is extruded within the extruded tube, at a distance from the trailing end of the tube. The die movement continues until the first extension is aligned within the throat and the trailing end portion of the extruded tube is completed. Thereafter, the steps are repeated to form additional extruded tubes. Each extruded tube has its trailing end portion and thickened ring section swaged radially inwardly first, until its outside diameter is less than the outside diameter of the tube, and secondly, until the inside diameter of the thinner wall trailing end portion is formed to the same internal diameter as that of the thickened section to thereby provide the integral spindle-axle tube.
摘要翻译：冷成型整体式主轴轴管的方法包括将管状坯料放置在具有挤出模头喉部的开口模具内，并用冲头推动坯料穿过模具喉部。冲头形成有冲压部分，该冲头部分向坯件施加压力以使其轴向移动通过喉部。冲头还具有紧密地装配在坯件内的延伸部，使得当冲头轴向推动管时，坯料在模具喉部和延伸部之间挤出以形成薄壁管。在坯料被部分挤出之后，移去冲头并插入第二坯料。然后将该第二坯料定位在冲头活塞部分和第一坯料的后端之间，使得冲头的进一步运动使第二坯料推动第一坯料通过模具喉部。此时，直径小于第一冲头延伸部的第二冲头延伸部布置在喉部内，使得向内增厚的环状环形部分在挤出管内被挤出，距离管的后端一定距离。模具移动继续直到第一延伸部在喉部内对齐并且挤出管的后端部分完成。此后，重复步骤以形成另外的挤出管。每个挤出管的后端部和增厚的环部分首先径向向内锻造，直到其外径小于管的外径，其次，直到较薄壁后端部的内径形成为相同的直径内径为增厚部分的内径，从而提供整体的主轴轴管。

摘要： Apparatus is provided for forming sheet metal ducts of varying conical configuration from pre-cut blanks having a baseline and element lines thereon. The apparatus comprises a frame supporting independent axially aligned feed rolls. Each roll is power driven by separate variable-speed motors providing for a different feed rate at each edge of the blank being formed. The driven sections of each feed roll are adjacent at the center of the axially aligned rolls. Idler rolls around the drive shaft form the remaining length of each roll. Corresponding segmented pinch rolls spaced axially at the center are arranged to pinch the blank to be formed against the feed rolls. Sensors are positioned between the spaced ends of the pinch rolls to detect the position of the blank baseline and the angularity of the element lines. The feed and pinch rolls are mounted on bases provided with bearings permitting axial shifting to maintain the blank baseline at the established position relative to the frame.A bending roll is spaced from the feed roll and adapted to have its axis positioned at an angle to the feed roll to produce a different radius of curvature at each edge of the blank as forming progresses.

摘要： This invention is a method for manufacturing a diaphragm bellows on a continuous basis, wherein by giving a pressure to the inside of a metallic pipe having the desired diameter, the pipe is bulged in the outer circumferential direction between opposed molds which hold the pipe and, by compressing the bulged part between molds, is formed into a steep projection of the desired shape. After removing the molds the pipe is pressed from both ends thereof to form the steep projections into flat shapes to obtain the desired diaphragm bellows and the above manufacturing procedure is repeated.

摘要： The invention relates to a muffler consisting of an external tube housing, pressed intermediate and terminal disks, and exhaust tubes for the exhaust gases extending through and connected to at least the terminal disks. The disks and tubes are each connected together by a gas-tight seal which includes a pair of beads bent around a disk flange into tight engagement with opposite disk sides. The beads are defined by outwardly folded portions of the tube and are disposed between tubular-shaped portions of the tube.
