Definitions

  • the invention relates to a shower for quenching of metallic workpieces with inductive hardening according to the preamble of claim 1.
  • Quenching showers are known in various embodiments.
  • the present invention relates to an annular shower body through which the rod-shaped workpiece to be hardened is passed.
  • This rod-shaped workpiece may be, for example, a rack.
  • the annular shower body is designed as a ring-tube-like hollow cylinder.
  • the ring tube is fed at one or more points water.
  • the inner cylinder of the hollow cylinder has circumferentially distributed radially inwardly directed water outlet openings through which the water exits in the direction of the workpiece.
  • the quenching shower can remain in the system and thus must not be dismantled from this, it is known to provide the hollow cylinder with a screw cap. This can be screwed by means of a corresponding lever-like tool.
  • the problem here is that there is usually little space for this tool, so that the lid can be unscrewed or screwed only laboriously. There is also the problem that the lid often jammed when turning.
  • the present invention seeks to provide a shower for quenching of metallic workpieces with inductive curing of the type specified with an improved way to open the shower body for cleaning.
  • a shower in the form of a ring-tube-like hollow cylinder is created, which can be easily opened and closed again.
  • the basic idea of the invention is that the cover is no longer turned on the cylindrical base body as before, but that the cover is loosely attached to the base body. This can be done easily without the aid of a tool.
  • the fixing device between the base body and the lid is then actuated, so that the two aforementioned parts are held together.
  • the fixing device is a separate component which is attached as a loose component or which is already attached to the base body and / or on the lid and only has to be actuated.
  • the disassembly of the shower is done in reverse, d. H. the fixing device is released, so that then the lid can be removed easily.
  • the development according to claim 2 proposes that the inner cylinder of the hollow cylinder is arranged on the cover. This has the advantage that when removing the lid of the inner cylinder can be cleaned with the water outlet openings outside the system. Similarly, the - remaining - body of the hollow cylinder is easily cleanable, in its fixed arrangement within the system.
  • the inner cylinder of the hollow cylinder is arranged on the base body. This means that only the annular cover must be removed to open the shower.
  • a first Au arrangement the fixing suggests the development according to claim 4.
  • the basic idea is that both the base body and the cover in the peripheral region have radially projecting projections.
  • the projections of both the base body and the lid correspond to one another when the two aforementioned parts are joined together. In this way can then attach to the projections, the fixing device.
  • the projections are evenly distributed around the circumference of the hollow cylinder.
  • the radial projections are radially protruding peripheral rings. These peripheral rings thus revolve both the main body and the lid and are radially over. This creates the opportunity to attach a corresponding fixing on these peripheral rings.
  • the projections or the peripheral rings encompassing clamping ring. This means that after the assembly of the base body and the lid of the clamping ring is circumferentially applied to the projections or peripheral rings, so that the two parts are held.
  • the peripheral rings and the clamping ring have a U-shaped or V-shaped profile.
  • the advantage is that thereby the clamping ring can be very easily applied.
  • the development according to claim 8 proposes that the above-described clamping ring is formed by two half-rings. These two half-rings are pivotally mounted at one end against each other, while the other two ends have a connecting these clamping lever.
  • This clamping lever is such that in the open state, the diameter of the two half-rings is increased, so that the clamping ring can be easily pushed axially onto the radial projections or radial peripheral rings.
  • By closing the clamping lever the diameter of the two half-rings is then reduced, so that they come to rest diameter close to the outer surface of the hollow cylinder.
  • a first Au is adopted the fixing suggests the development according to claim 9.
  • an annular cover is provided, which is articulated via a hinge on the hollow cylinder-like base body. This means that to open the shower the annular lid is simply opened, so that the interior of the shower is accessible for cleaning purposes. For the recommissioning of the shower then the lid is pivoted back into the closed position and fixed there.
  • the fixing device is arranged on the opposite side of the lid relative to the hinge.
  • a fixing device a clamping lever with an over-center position, a locking bolt or the like. Be provided.
  • the first embodiment of the shower for quenching of metallic workpieces with inductive curing has a ring-tube-like hollow cylinder 1. This consists of a base body 2 and a lid. 3
  • the main body 2 consists of a cylinder jacket, which has on one side an annular bottom. In the lateral surface of the main body 2 open two water supplies. 4
  • the lid 3 is annular and has an inner cylinder 5 in the region of the central circular opening. This is provided with water outlet openings 6.
  • Both the base body 2 and the lid 3 have in their contact area radially projecting projections 7 in the form of radially projecting peripheral rings.
  • a clamping ring 8 For fixing the lid 3 on the base body 2 is a clamping ring 8. This consists of two half rings. These are mounted pivotably at one end with each other. Between the other two ends is a clamping lever. 9
  • Fig. 4a shows the shower in the closed state.
  • the fixing device with the clamping ring 8 is thereby in the fixing position.
  • the clamping ring 8 is placed with its U-profile on the corresponding projections 7 in the form of the peripheral rings such that the two legs of the clamping ring 8 engage around the projections 7.
  • the tensioning lever 9 is in the folded closed position, which defines an over-center position.
  • Fig. 4c shows the situation that the lid 3 is removed with its inner cylinder 5 of the main body 2.
  • the clamping ring 8 is so expanded with its two half rings that the projections 7 are free in the form of the peripheral rings.
  • the shower can then be cleaned.
  • the base body 2 remains mounted on the system, while the cover 3 can be removed in its inner cylinder 5 and cleaned outside the system.
  • the assembly of the shower is then in the reverse order as previously described.
  • a second embodiment is in the Fig. 5 to 8 shown.
  • a hollow cylinder 1 is provided consisting of a base body 2 and a lid 3.
  • the main body 2 is formed as in the first embodiment, except that the inner cylinder 5 is not fixedly arranged on the lid 3, but on the base body 2.
  • the inner cylinder 5 can also be arranged on the cover 3, just as in the first embodiment, the inner cylinder 5 can also be arranged on the base body 2.
  • the lid 3 is arranged by means of a hinge 10 on the base body 2.
  • a fixing device On the opposite side of the lid 3 relative to the hinge 10 is a fixing device. In the present embodiment, this is formed by an angling of the lid 3, which engages in the closed position of the lid 3 in the base body 2 and is fixed there, for example by means of a bolt.
  • the functionality here is as follows: To open the shower the fixing device is unlocked. As a result, the lid 3 is free and can be opened by means of the hinge 10. As a result, the interior of the shower is free and can be cleaned.
