摘要： The present invention provides a method and an apparatus for manufacturing an interlocking pipe obtained by easily and precisely shaping a pipe with a circular cross section or with the edges of the cross section nearly forming a circle in a non-loose manner, so as to provide excellent machining performance when the interlocking pipe is cut off and provide excellent operation efficiency for the apparatus itself. A metal band plate is helically wound onto a core member with a circular cross section or with the edges of the cross section nearly forming a circle. Clamping device is freely assembled at a front end of the code member in a detachable and switchable manner, and synchronously rotate in accordance with instructions from a main computing-controlling member, so as to prevent the metal band plate from being loosened, thereby to manufacture the interlocking pipe efficiently.

摘要： An adjustable horn or mandrel for a spiral pipe forming machine. Such machines are made for continuously forming metal pipe from an elongated sheet of metal where the sheet is curled into adjacent helical convolutions in a multiple roll pipe forming head. The head includes a mandrel, and in accordance with the invention a mandrel mount is provided for vertical adjustment of the mandrel. The mandrel mount has opposite side supports sandwiching the mandrel and a motor mounted for raising and lowering the mandrel between the side supports. Raising and lowering is accomplished via a pair lead screws secured to the mandrel, each having a gear threadedly engaged thereon and which is driven by the motor. The mandrel is also horizontally adjustable.

摘要： An apparatus for making helically wound interlocked flexible pipe includes a rotating head mounted for rotation about a main shaft. Two supply spools of strip material are mounted on the rear side of the rotating head, a take off guide beam assembly being used to take off flat strip material from one of the spools, and guiding it to the rotating head. The rotating head is mounted on the main shaft for rotation therewith and supports a tool head assembly including a roller forming mill for forming the strip material. The strip is guided from a point behind the rotating head to a point in front of or downstream from the rotating head along the shaft. A face plate assembly, which supports the pressure rollers for closing and interlocking the successively adjacent turns of the formed strip, is axially spaced from the tool head assembly. A constant supply or reservoir of formed strip material, in the form of a loop in a substantially circular path, is provided to insure proper supply of formed strip material on demand to the pressure rollers. A sensor is used to monitor the instaneously contractions and expansions of the supply loop from its nominal size, such variations being utilized to modify and adjust the instaneous speed of rotation of the forming rollers. A rewinding system is used to rewind flat strip material on the other non-feeding supply spool. The apparatus assures simple and convenient start up of production of flexible pipe, and efficient operation without buckling or damage to the strip material.

摘要： This invention relates to apparatus for manufacturing tubes by the helical coiling of a strip into successive convolutions. The strip is preferably of a corrugated sheet metal. The coiling means of the apparatus comprises a plurality of non-driven freely rotatable and radially adjustable guide rollers adapted to guide and support the strip during the formation of a convolution. These rollers are arranged on a circle so that they engage the convolution at its outside. Arranged at the point of the strip entry into the coiling means is an inner and an outer connecting roller, the inner connecting roller positioned within and the outer connecting roller positioned outside the circle on which the guide rollers are situated. The connecting rollers have the purpose of joining a convolution after its travel past the guide rollers to the incoming strip so that convolution and strip overlap each other. By controlling peripheral rotational speed of the connecting rollers and providing the connecting rollers with various surface configurations, the joint between the incoming strip and the just formed convolution can be controlled to insure a proper joining therebetween as well as dimensional control of the diameter of the tube being formed.

摘要： In a method for producing welded helical seam tubes having optimized tube geometry a metal strip is helically formed into an open seam tube by means of a forming unit and the converging strip edges are welded together, wherein an actual diameter determined on the welded tube is compared with a specific target diameter and a possible deviation lying outside a tolerance threshold is used to correct the actual tube diameter, wherein the strip edges are completely welded in a two stage step, including tack welding as a first step immediately after the shaping to form an open seam tube and thereafter final welding as a second step. The tube diameter is measured after the complete shaping to form an open seam tube and before the final welding. For this purpose, the diameter measuring device is arranged in such a way that either the completely shaped open seam tube or the only tack-welded tube is measured.

摘要： An improved apparatus for continuously forming spirally corrugated metal pipe from an elongated sheet of metal which is first impressed with longitudinal corrugations in a corrugating device and the spiralled into a pipe in a three roll forming device, each roll of which is composed of a plurality of individual rollers. Each individual roller is mounted for rotation about its axis in an individual roller yoke, with each of the roller yokes of each roll being in constant abutment, but with adjacent roller yokes being uninterconnected. Individual roller yokes of each roll are positioned along a guide, with each yoke being both freely displaceable along the guide along a horizontal path generally parallel to the axis of the formed pipe, and also pivotable about a vertical center axis. One of the rolls, termed herein a horn roll, is situated to contact the inner wall of the pipe as it is formed, while the other two rolls, respectively termed the lead and buttress rolls, are situated to contact the outer wall of the pipe. A rigid frame member is attached to the corrugating device, extending from the corrugating device into the three roll forming device in contact with either end of each of the lead and buttress rolls. The buttress roll is the farthest downstream of the three rolls and is adjustable on an angle to the vertical in order to vary the diameter of successive helical convolutions of the metal sheet, therefore varying the diameter of the pipe produced. A downwardly depending adjustment arm is attached to an end roller yoke of the horn roll and slideably engages the rigid frame member. When the corrugating device is pivoted relative to the three roll forming device, the rigid frame member automatically relocates the positions of each of the three rolls and adjusts spacings between center axes of adjacent rollers of each roll to assure that the individual rollers constantly and correctly align with the corrugations of the metal sheet as it enters the forming device and is spiralled into helical convolutions.

摘要： A machine and method for making spiral pipe from a continuous strip of sheet metal including a corrugating mill which forms corrugations in the strip and drives it through a three-roll bending mill which bends the strip into helical convolutions and guides adjacent edges thereof into an interlocking relationship and a pair of lock up rolls for crimping the interlocked edges of the convolutions into a continuous seam, which rolls are manually or automatically adjustable radially relative to the pipe axis whereby its diameter may be accurately controlled. Adjustment of said rolls radially inwardly effects a diameter increase whereas adjustment outwardly decreases the diameter of the pipe.
