Definitions

  • This invention is concerned with improvements in and relating to tools, such as those used for flaring and particularly, though not exclusively, those used for expanding the ends of brake pipe fittings.
  • a tool for use in altering the diameter, shape or configuration of an article including a die for controlling the shape to which the article deforms and the tool being adapted to cooperate with means for applying pressure to deform the article, wherein the die is provided in a die block which is removable from the tool.
  • the die can readily be replaced whether for repair or to insert a die block containing a die of different size.
  • the tool may be provided with two or more dies, preferably one die is provided at one end of a passage provided in the tool and another die is provided at the other end of the passage.
  • the tool has a longer life as two dies will last longer than one before becoming unusable due to damage.
  • a tool for use in altering the diameter, shape or configuration of an article including means for controlling the deformation of the article and the tool being adapted to cooperate with means for applying pressure to deform the article, wherein the deformation controlling means comprises one or more passages through the tool, one or more of the passages being provided with a die portion at one end and a further die portion at the other end.
  • the dies may be provided within a die block which is removable from the tool. In this way replacement of the die is made easier and cheaper as complete replacement of the tool is not required.
  • One or more of the dies provided may be of different sizes and/or be of different configuration to one or more of the other dies. In this way a tool is provided which is far more versatile as different sizes of flaring or different types of flaring can be effected without the need to change tool or die block.
  • the tool may include two body components having a closed and released state, the components cooperating in the closed state to retain the releasable die block in the tool, and in the released state permitting the removal of the die block.
  • the body components are pivotally connected so as to provide an easily and accurately reproducable transition from the closed to released state and vice versa.
  • pivotal connection is provided at an end of the tool, ideally at the end opposed to a handle portion used for supporting the tool, for ease of handling.
  • the die block is preferably accommodated in an aperture in the tool.
  • the aperture is defined in part by one of the tool body components and in part by another. In this way easy access can be obtained in the released state.
  • the body components are held in the closed state by retaining means which engage with the body components. This ensures the die block is firmly held in place during flaring and no undesirable separation of the body components occurs.
  • the retaining means comprise a threaded member.
  • the threaded member may be pivotally attached to one of the body components and cooperate with a notch on the other. Additional restraining force may be applied by tightening an additional member on the threaded member so as to abut with the second body component.
  • a kit comprising a tool according to the first aspect of the invention and/or a tool according to the second aspect, with a removable die block, wherein the kit includes one or more additional die blocks.
  • the kit includes die blocks which provide a range of sizes of dies and/or dies for a range of flaring applications.
  • the kit thus provided represents a versatile and readily-to-hand set of apparatus.
  • a die block having one or more through passages, one or more of the passages being provided with a die at one end and a further die at the other end.
  • the dies are of different sizes and/or configurations.
  • Sets of two or more such die blocks may be provided.
  • a tool for use in altering the diameter, shape or configuration of a tubular article including a die for controlling the deformation of the article and the tool being adapted to cooperate with means for applying pressure to deform the article, wherein the pressure is applied by hydraulically activated means.
  • the tool is hand held, easing its use and location of use.
  • the tool may be provided with a clamping member which cooperates with the pressure applying means.
  • the pressure applying means may cooperate with the clamping member by means of a threaded engagement.
  • the clamping member may be releasable from the tool.
  • the clamping member may engage the tool by means of threaded connectors.
  • notches in the clamping member may cooperate with ridges on the tool, or vice versa, to position the clamping member relative to the tool.
  • the tool 1 comprises a handle member 2 and housing member 3 pivotally mounted relative to each other at their respective ends 4, 5 by a pin 6.
  • Each member 2, 3 has a channel 7, 8 extending over their full width, which channels oppose each other in the closed position, when surface 9 abuts surface 10.
  • the channels 7, 8 accommodate a removable die block 11 (shown in Figure 3). In the closed position the die block 11 is restrained within the channels 7, 8.
  • the handle member 2 also has a hand-held portion 12 by means of which the operator controls and positions the tool.
  • a threaded member 13 is pivotally mounted between two projections 14 from the handle member 2 base by means of a pin 15. With the housing member 3 in the closed position the threaded member 13 can be swung so as to pass between opposing projections 16 on the housing member 3. The nut 17 can then be screwed down until it abuts surface 18 on housing member 3. The members 2, 3 are thus retained in the closed formation.
  • the die block 11 comprises a rectangular block with a central axially aligned passage 19 having enlarged end portions 20, 21.
  • the transition surface 22 between the passage 19 and enlarged portion 20 onto the right end is radial, so providing for DIN type flaring.
  • the left end provides an axially inclined radiating surface 23, so providing for SAE type flaring.
  • the tool 1 is opened and the die block 11 having the desired size passage 19 is inserted in the channel 7, 8.
  • the die block 11 is inserted so that the desired transition surface configuration is on the desired side of the tool 1.
  • the tool 1 is then closed and the handle and die housing members 2, 3 respectively are restrained relative to one another by the threaded member 13 as previously discussed.
  • FIG. 4 This provides for a tool assembly having a configuration as seen end-on in Figure 4.
  • Each of the housing and handle members 2, 3 are provided with a rib 28 raised relative to the member.
  • the rib 20 runs along each side of each member.
  • An hydraulic mounting member 25 can then be slid over the end of the tool 1 and run along the ribs 28.
  • the hydraulic mounting member is provided with notches 26 which cooperate with the ribs to resist direct movement away from the members 2, 3.
  • the hydraulic mounting member 25 is provided with a threaded aperture 27 into which the hydraulically operated stamp can be screwed.
  • the stamp is consequently held in position relative to the members 2, 3 during the flaring operation.
  • Flaring is effected by applying hydraulic pressure to the stamp so forcing the cone into the pipe and expanding it to the die configuration.
  • the flared pipe is extracted by removing the hydraulic stamp, hydraulic mounting member, threaded member and opening the members 2, 3 in the reverse of the aforementioned procedure.
