Definitions

  • a forming device for carrying out controlled deformation of tubes, especially tubes of heat exchangers, placeable between the table and pressure bar of the mechanical press which comprises a lower forming plate and an upper forming plate that are coupled by guide devices, and die elements arranged on mutually counter surfaces of the lower forming plate and upper forming plate.
  • An important type of heat exchangers whose essential function is transferring heat between two fluids at different temperatures, are tube heat exchangers. They are used for heat transfer between two gases, between two liquids, or between a liquid and a gas.
  • transferring heat from hot water flowing in a tube to the surrounding environment is more intensive if the water flow is turbulent. Transition from laminar to turbulent flow is due to local alterations in water flow rate which are caused by obstacles standing in the way of the flowing water, that means by irregularities in the inner wall of the tube. These have been formed as raised surface irregularities of different shapes projecting in the internal diameter of the tube.
  • a direct tube of the heat exchanger accommodates individual dimples arranged in the shape of a spiral which form protrusions on the inner wall of the tube.
  • the instrument of production is the forming head which rotates against the tube and at the same time both the forming head and the tube are mutually longitudinally shifted.
  • the head has three form blocks, the outer cylindric surface of which has circumferentially a row of individual moulding protrusions which are during the industrial process pushed into the outer surface of the tube from the outside.
  • DE102008031158A2 and DE102008062704A1 disclose a modification of a tube of circular, elliptical or other cross section which has at least one longitudinal division plate. Tubes of rectangular cross-section are shown having at least one side into which point or crosswise protrusions are pushed from the outside. Their shape and slope with respect to the longitudinal axis of the tube is achieved by the forming roller, which accommodates, for instance, circumferential oblong protrusions sloping with respect to the axis of the rotation of the forming roller. The tube is shifted with respect to the forming roller perpendicularly to the axis of the rotation thereof.
  • DE102009051280A1 devises forming a flat tube of the heat exchanger from a long semi-finished product which has in certain longitudinal sections moulding dimples forming internal protrusions on wide areas of the tube which alternate regularly with longitudinal sections which have no dimples. Such a semi-finished product which is actually endless is then in the areas without dimples divided into final products having lentgths that are multiples of the length of the module defined by the section without dimples and that with dimples.
  • An object of the present invention is to provide a forming device for carrying out controlled deformation of tubes comprising a lower forming plate, an upper forming plate and die elements arranged on mutually counter surfaces of the lower forming plate and upper forming plate, wherein its essential feature is the fact that the die elements are coupled to the corresponding forming plate in a manner such that they can be demounted or adjusted, the forming plates being coupled to devices for adjusting the position of the processed tube with respect to the forming plates along the longitudinal axis of the tube and along the direction of shifting the tube round its longitudinal axis and to devices that secure the tube in the set position.
  • This device is universal, easily adjustable, wherein it is possible simply to choose the length of the processsed tube and the shape of individual irregularities. It can be used for tubes of different diameters and made of various plastically deformable materials. Another advantage is relatively high manufacturing productivity.
  • Die elements are mounted to a corresponding forming plate at equal mutual distances or at different mutual distances. Preparatory time for changing the mutual position of the die elements represents only a little waste of production time.
  • At least one forming plate comprises an adjustable stop device defining the mutual distance between the forming plates at the end of the moulding stroke.
  • the forming plates there is a spring device the force of which acts in the direction against the forming plates approaching each other.
  • the forming plates automatically move away from each other, which enables to transfer the processed tube before another squeezing stroke, or remove it from the gap between the forming plates.
  • At least one pressure spiral-shaped spring is employed. It is advantageous when the spiral-shaped spring is coupled to a guide device by which it is guided.
  • the die elements connected to the lower forming plate differ in the profile of the forming portion from those connected to the upper forming plate and /or die elements connected to one forming plate differ from each other in the profile of the forming portion. That further extends the variability of the forming device according to the invention.
  • FIG. 1a represents a top view of an embodiment of a deformed tube
  • figure 1b shows a bottom view of an embodiment of a deformed tube
  • figure 2 shows a tube from figure 1 a in S direction view
  • figure 3 shows a longitudinal cross-section of the tube of figure 1 a taken along the line A-A
  • figure 4 represents an angle view of the forming device assembly
  • figure 5 shows a top view of the lower plate of the forming device
  • figure 6a is a scheme side view of a die element in an example of embodiment
  • figure 6b shows a front view of a die element in an embodiment from figure 6a .
  • the forming device according to the present invention is intended with advantage for carrying out controlled deformation of tubes, made especially of steel or copper, having small and very small diameters.
  • tubes made especially of steel or copper, having small and very small diameters.
  • These tube dimensions are mostly used in lesser heat exchangers, where, besides shape alterations in the inner wall of tubes, also a small inner diameter of the heat exchanger tube itself contributes to intensification of heat transfer.
  • An example of embodiment of the forming device according to the present invention as illustrated comprises a lower forming plate 1 and an upper forming plate 2 .
  • a hand-held stabilizer 3 of the processed workpiece which is in the example of embodiment a semifinished product in the form of a circular tube.
  • the final product is a tube 4 formed by controlled deformation designed for instance for a heat exchanger.
  • eight oblong die elements 12 are attached to the top surface 11 of the the lower forming plate 1 arranged in a row along the length of the lower forming plate 1 (for simplification, only one die element 12 is shown).
  • the die elements 12 are positioned towards the top surface 11 of the lower forming plate 1 always by pins (not shown) in two end guide holes 111 and are fixed to the lower forming plate 1 always by means of a bolt (not shown) through a mounted fastening hole 112 in the lower forming plate 1 . They are arranged in the cross direction with respect to the axis 120 of their row, with respect to which they are all sloped under specific angle ⁇ . In an example of embodiment the angle ⁇ equals 45°.
  • a diffferent number of die elements 12 is mounted to the forming plate, wherein a plurality of guide holes 111 and their respective fastening holes 112 enables to arrange the die elements 112 which are being used and fixed at equal or different mutual distances, for example when some guide holes 111 and their respective fastening holes 112 are not occupied.
  • FIG. 6a, 6b An example of embodiment of a die element 12 is shown in Figure 6a, 6b .
  • the die element 12 has a profile of a bar whose fastening portion 121 with which it engages with the top surface 11 of the lower forming plate 1 has a rectangular cross-section, and the moulding portion 122 itself has a roof-like profile. Near the edges on the engaging surface of the die element 12 there are two centering holes 123 for pins (not shown) and a threaded hole 124 for a fastening bolt (not shown). It is apparent that in other embodiments the profile of the moulding portion 122 can be any suitable different shape, such as cylindric shape and the like.
  • a holder 14 carrying a stabilizer 3 of the processed workpiece is mounted to one butt of the lower forming plate 1 .
  • the stabilizer 3 comprises an overhung guide bar 31 with a row of perpendicular through holes 311 having equal mutual pitches. In an embodiment which is not shown these pitches can differ, their size being firmly set.
  • a workpiece grip 32 provided with a through grippping device 321 of workpiece (not shown) and a device for securing the workpiece grip 32 (not shown) in a specific through hole 311 is placed in a sliding manner on the guide bar 31 .
  • the workpiece grip 32 is located in a manner such that the processed tube is placed above the lower forming plate 1 above the row of die elements 12 in parallel to this row.
  • the mechanism of the hand-held stabilizer 3 or more precisely its workpiece grip 32 . enables to shift the workpiece in any way round its longitudinal axis and secure it in this position.
  • the upper forming plate 2 is substantially a mirror reflection of the lower forming plate 1 . That applies to the position of the axis of the row of die elements 12 and to the angle ⁇ of their slope with respect to the axis 120 of their row and to the pitch distances of the die elements 12 . However, along the axis 120 of the row of die elements 12 these axes of the forming plates 1 , 2 towards each other are shifted in the lengthwise direction.
  • the upper forming plate has threaded holes 22 , in which adjusting screws 23 (illustrated by the hatched part) protruding from the bottom surface 24 of the upper forming plate 2 are located.
  • the adjusting screws 23 are at their lower end counter towards the top surface 11 of the lower forming plate 1 provided with stop heads 231 .
  • the upper forming plate 2 When the forming device is assembled the upper forming plate 2 is fitted by the guide holes 21 on the guide bolts 13 fixed in the lower forming plate 1 , whereby spiral-shaped springs 13 are partly preloaded. This assembled position is reached after the forming device is set into preparatory position in which the bottom surface 15 of the lower forming plate 1 lies on the table of the press (not shown), wherein the pressure bar of the press (not shown) is in contact with the top surface 25 of the upper forming plate 2.
  • the tube is put in the grip device 321 of the workpiece grip 32 which is shifted on the guide bar 31 of the hand-held stabilizer 3 into the desired position. If the workpiece is to be deformed from the end portion, it is gripped in the hand-held stabilizer in a position where its end is at the desired small distance behind the last die element 12 . At the same time the workpiece grip 32 of the stabilizer 3 is secured with regard to its longitudinal position towards the forming plates 1 , 2 in the corresponding hole 311 of the guide bar 31 , the workpiece being ensured against turning round its longitudinal axis.
  • the backstop position of the device is defined, that is the maximum approach of the upper forming plate 2 to the lower forming plate 1 , which defines the depth of the deformation of the tube walls.
  • the stroke itself is performed mechanically either by employing the press drive, or manually on a non-powered press, for example a press with a pressure ridge bar. With regard to the size and material of the tubes even hand drive is convenient.
  • the forming device is set as described above in an example of embodiment, eight pairs of direct dimples 41 arranged in parallel against each other and mutually shifted at distance p are led into the tube from the top as well as from the bottom.
  • the upper forming plate 2 moves up after the stroke of the pressure bar.
  • the workpiece grip 32 of the stabilizer 3 is released and moves along the guide bar so that a new row of prepared deformations can extend the previous row.
  • the main advantage is simplicity of the forming device and relatively high productivity of labour. It is also possible to make alterations to the arrangement of protrusions around the axis of the tube 4 rotation, their pitches and the angle ⁇ of the slope of their direction with respect to the longitudinal axis of the tube 4 by means of a guide bar 31 . By effortless replacement of the die elements 12 it is possible to modify the shape of the protrusions.
