Definitions

  • the invention relates to portable anvils intended in particular for farriery and more specifically a so-called “bigorne” model comprising, on either side of a table, two horns, one round, the other square, this portable bigorne allowing a farrier to practice his art with maximum ease, even in itinerant conditions.
  • the farriery market has undergone very significant changes in relatively few years: - the horse park has been significantly modified since less and less draft horses are used. An important market remains especially for the saddle horse, the leisure horse, the horse dedicated to sports (races, polo); - in addition, the work of the farrier has also evolved, one now finds in the trade, all prepared, a great variety of irons of all sizes and all styles.
  • the farrier no longer has to make the iron, but more simply he must choose the appropriate iron and adjust this iron at the foot of the horse.
  • a traditional anvil, made of cast metal, is by no means portable and weighs up to 200 to 300 kg.
  • Makeshift means metal blocks of any shape are not very recommendable for the quality of work expected of a good craftsman.
  • Anvils of goldsmiths do not support the energy deployed, nor do they allow to obtain the desired curves.
  • Document DE-C-448 080 describes an anvil formed from an ingot, one end of which is formed as a base, the other end being crushed, perpendicular to the initial axis of the ingot, the fibers metal roughly aligned along the axis of the table.
  • the resistance of the metal although increased, does not make it possible to obtain a light anvil with a large working surface.
  • Application GB-A-273 634 describes a method of manufacturing an anvil by oxy-cutting from a metal ingot, various parts being able to be subsequently added by welding.
  • Application GB-A-273,634 does not, however, give any indication of a way of making a particularly resistant anvil, of reduced weight and with a large working surface.
  • the object of the invention is to produce an anvil, essentially for the use of farriery, easily transportable by a single man, with extended worktops and nevertheless having excellent robustness.
  • Another object is that this anvil offers a wide variety of support points for shaping metal objects.
  • a more particular purpose of this anvil is to be able to work horseshoes of all sizes there.
  • Another object is that this anvil has a long life.
  • Another aim is the placing on the market of a tool for working with high quality iron, with a reasonable manufacturing cost.
  • the object of the invention is a steel anvil extending along its substantially horizontal longitudinal axis and along a vertical axis and comprising a base, a body comprising a round horn and a square horn arranged on either side of a table, along the longitudinal axis, and a shaft connecting the body to the base along the vertical axis;
  • the base in this anvil, is in the form of a plate and has a substantially planar lower face, the length of which along the longitudinal axis is greater than its width in a direction perpendicular to this axis;
  • the barrel flares up and down from an intermediate zone of smaller section;
  • the entire anvil is formed by a first part comprising the body and a barrel section delimited by a plane substantially parallel to the underside of the base and located in said zone of smaller section, and of a second part comprising the base and a barrel section delimited by this same plane;
  • this anvil weighs between 20 and 30 kg.
  • the body of the anvil is made of steel alloyed with nickel, chromium and molybdenum having a high resilience both at high and at low temperature and being able to be forged.
  • the base is made of carbon steel capable of being forged.
  • the free ends of the two barrel sections preferably have a chamfer on their periphery, these chamfers forming, when the barrel sections are assembled, a groove capable of accommodating a weld bead, the free end of at least one of the two sections being released in its central part, a rib remaining along this periphery.
  • the rib advantageously has a width of between 1 and 5 mm.
  • the chamfer of the barrel section connected to the body forms, with the plane delimiting the two barrel sections, an angle between 20 and 40 °.
  • the chamfer of the barrel section connected to the base forms, with the plane delimiting the two barrel sections, an angle of 10 to 30 °.
  • the round horn of the anvil preferably has a width greater than 22 cm.
  • the anvil advantageously has a flat surface below the upper surface of the table, parallel to the latter, substantially at the level of the upper edge of the round horn.
  • a square opening is made in the upper surface of the table, said opening being of dimensions suitable for the insertion of anvil tools and being pierced right through so that an extractor member for said tools can be inserted through the lower opening of this square opening.
  • a work surface is provided between the edge of the square opening and the edge of the table.
  • an oval opening, with rounded edges in a plane, suitable for the shaping of aluminum irons crosses the table right through.
  • Another object of the invention is a method for manufacturing anvil in steel extending along a substantially horizontal longitudinal axis and along a vertical axis and comprising a base, a body disposed along the longitudinal axis and a barrel connecting the body to the base along the vertical axis, characterized in that it comprises the following operations: - Preforming by forging of a piece of alloy steel intended to form the blank of an anvil body (2) and an adjoining barrel section; - preforming by stamping a second piece of steel intended to form the blank for a base (3) and an adjoining barrel section; - Forging by stamping of the blank intended to form the body of the anvil and an adjoining barrel section; - forging by stamping of the second blank, intended to form the base for the anvil and an adjoining barrel section, the body and the base being stamped so that the steel from which they are made adopts a fiber structure, the fibers of this structure being preferably oriented along the longitudinal axis of the future anvil, in the body and in the base and along the vertical axi
  • the method further comprises clearing the end of one of the sections of was in its central part, a rib being formed along the periphery of this end.
  • the preferential orientation of the fibers gradually changes from an orientation along the longitudinal axis (in the body and in the base) to an orientation along the vertical axis (in the two barrel sections) and this by following deformations that are subjected to the blanks during forging.
  • An advantage of the invention is that, because of its manufacturing method, the structure of the steel is oriented axially, which allows, at equal strength, to considerably reduce its shapes and therefore its weight; the central mass of a traditional anvil is here reduced to a pillar with a narrow waist.
  • Another advantage is that the horns offer significant clearance, which allows for more precise work.
  • each anvil being produced in two pieces, it is possible to use steels of different shades for the base and the body, it is therefore not necessary to use for the base a steel of as good quality as for the body.
  • Another advantage is that, given the extent of the work plan, very differentiated work can be carried out with great precision (in particular pulling pliers).
  • the anvil according to the invention comprises two separate parts, the body 2 and the base 3. These two parts are arranged along the same horizontal axis.
  • the base 3 is flattened and has four feet 4 which extend along the four corners of a quadrilateral whose long side is disposed along the axis of the anvil, the short side of this quadrilateral is wider than the projection of the body 2 on the base 3.
  • the body 2 and the base 3 are joined in the middle by two barrel sections 5, 6 which are thinner from each of these two parts 2, 3 and are joined by a weld 7 at their free ends.
  • the body 2 is extended along the longitudinal axis by a round horn 8, whose upper edge is horizontal and whose length is, in this example, about 23 cm.
  • This horn 8 has a significant clearance over its entire length, it is therefore possible to work the irons therein by presenting them practically from all angles without being obstructed beyond measure by the body 2 or by the base 3.
  • a flat surface called "level break” makes the transition between the base of the round horn 8 and a table 10 which occupies the upper face of the body 2.
  • This level break 9 has two vertical sides 11 and rounded angles, which makes it possible to conveniently work on irons of larger dimensions, such as irons for draft horses.
  • a table 10 with sharp angles extends to the upper part of the body 2, making it possible to carry out conventional work.
  • a square opening 12 of standardized dimensions is drilled right through into the table 10. This opening 12 allows tools to be accommodated therein (not shown) suitable for working and shaping iron.
  • the lower orifice 13 of the square opening 12 simplifies the extraction of the tools after use (by insertion of a lever, for example).
  • a rim 14 with sharp angles is formed and protrudes so that it can pull clips of any size easily.
  • the table 10 is extended, at its other end, without a solution of continuity, by the upper face of the square horn 15 (also called heel).
  • the upper edges of the square horn are rounded so as to facilitate the opening of irons of different dimensions. It also allows cold irons to be worked.
  • constricted section of the barrel (5, 6) of the anvil means that the lower face of the square horn 15 is also largely free, which facilitates work.
  • stamping makes it possible to further increase the rate of metal working.
  • the axis of the dies and the axis of the ingots can be made to coincide, which makes it possible to keep the metal fiber in its original orientation and considerably increase the rate of wrought without additional energy input.
  • the table 10 is also pierced right through by an oval groove 17 (shown in section in Fig. 5).
  • the angles 18, 19, 20 of this groove 17 are rounded along the plane of its largest sides. Loose irons (such as those used for racehorses) can be slid into this oval groove and worked easily.
  • a groove 21 of 10 mm is made transversely near the end 22 of the square horn 15, parallel to this end 22. Any type of iron, even carrying clips, can be uncorked without problem thanks to the presence of this groove 21.
  • Fig. 4 shows in more detail the connection of the ends of barrel sections 5, 6.
  • the two ends have been pre-machined so as to offer a contact plane substantially parallel to the base 3, the internal face of one of the ends has been released with a thickness e (where e is between 1 and 3 mm) of so as to limit the contact between the two ends to a rib 23 of width a (where a is between 1 and 5 mm) which goes around the barrel, which makes it possible to reduce the tensions linked to differential shrinkage.
  • a chamfer 24 is formed on the periphery of each barrel section 5, 6, the wall of this chamfer 24 making, with the plane delimiting the two barrel sections, an angle ⁇ (for the base) and ⁇ (for the body ), ⁇ varying between 10 and 30 ° (with an optimum of 20 °) and ⁇ varying between 40 and 50 ° (with an optimal value of 45 °), the bottom of the throat (c + d) having approximately 2 mm.
  • the two chamfers 24 form a groove suitable for drawing a weld bead between the body 2 and the base 3.
