Definitions
- the invention relates to a device and a method for carrying out a blast treatment of the inner wall of a channel with a granular jet Material according to the preamble of claim 1 and the preamble of Claim 11.
- the so-called shot peening is a known method of improvement the strength of metallic surfaces; For example, at the Maintenance of aircraft the wing leading edges with a jet of Impacted metal balls. It is already known from US-A-3 485 073 the walls of cavities in metallic objects of a blast treatment undergo the shot peening by means of a longitudinal channel having introduced stiff lance into the cavity; at the front Lanzenende is a so-called inner jet nozzle, in which the Lance longitudinal channel opens and the one inclined relative to the lance axis Has inclined surface, which serves for the deflection of the shot peening, so that this exits the jet nozzle transversely to the longitudinal axis of the lance.
- This known Although device can be to carry out a blast treatment of Inner wall of straight channels use, but not if such Channel has one or more curves, as in metal pipes
- the case is, for example, for stabilizers on motor vehicles as well used for the production of camshafts.
- US-A-4 706 356 discloses only the blast treatment of the interior walls of straight metal pipes by means of an inner jet nozzle of the type described above Art, which is attached to the end of a flexible hose, the the supply of a jet of small metal balls is used. It has been shown that such a device for a blast treatment of the inner walls curved channels is unsuitable.
- the invention was therefore based on the object, a device with the Features of the preamble of claim 1 to create, with which the Inner walls of channels, which have one or more curves, undergo a blast treatment, in particular the inner walls of at least one bend having metal pipes.
- the invention proposes, in such a device to use the features of the characterizing part of claim 1, and for preferred embodiments of the device according to the invention recommended a flexible hose, which in particular is a Rubber or plastic hose is, preferably a polyurethane hose.
- a flexible hose which in particular is a Rubber or plastic hose is, preferably a polyurethane hose.
- the hose such plastics, the sufficient against the guided through the tube particle beam Resistant, on the other hand, but also sufficiently flexible, as this polyurethane is the case.
- the hose outer side helically surrounding wire-shaped Element of the device according to the invention is when inserting this device into the canal and during a blast treatment Sliding the hose in the channel the sliding friction between the Channel wall and the hose is reduced, so that this sliding friction clearly is less than when the hose lie flat against the channel wall would; this is especially true when the wire-shaped element is one of the tube wall facing away from rounded tip and / or out a lower sliding friction causing material, in particular from a suitable metal or a suitable low-friction Plastic.
- US-A-1 504 945 discloses a hose protector in the form of a a tube of helically surrounding wire whose ends are metallic Threaded sockets are attached, which in turn on the hose ends pushed on and attached to the hose.
- the tube at least almost over its entire, to be introduced into the channel Length provided with the wire-shaped element.
- the ends of the wire-shaped element are in Hose longitudinal direction held relative to the hose immovable to the Moving the tube in the channel to be treated a shift to avoid the helix on the hose.
- the diameter of the wire-shaped element at most equal to and preferably smaller than the wall thickness of Hose is.
- the drawing shows a longitudinal section through the inventive Device and by adjoining parts of a jet treatment device and by a metal pipe to be treated, in which the inventive Institution was introduced.
- an S-shaped curved metal pipe 10 is shown, whose Inner wall surface should be shot peened to ensure the durability of the Tube to increase load changes.
- a shot peening into a in the drawing partially represented tube 12 is fed, in which a Support sleeve 14 is screwed.
- a clamping sleeve 16 screwed so that between an inner cone of this clamping sleeve and an outer cone of Support sleeve 14 clamp a tube 20 of the device according to the invention leaves, with the hose end elastically expanded by the support sleeve 14 becomes.
- a nozzle body 22 of a jet nozzle 24 attached, wherein the hose end cross-nozzle body with the Hose z. B. can be glued.
- a deflection piece 26 is used and for example by means of a suitable Adhesive fixed in the nozzle body; this deflector has an opposite the hose axis 20a inclined by 45 ° baffle 26a through which the Balls of the shot peer are deflected by 90 °, so that they the jet nozzle 24 through an outlet opening 22a of the nozzle body 22 in the direction of the arrow A leave and impinge on the inner wall surface of the metal tube 10, when the device according to the invention is inserted into the tube 10.
- the outer diameter must the nozzle body 22 in the region of its free end clearly be smaller than the inner diameter of the metal tube 10th
- the particular polyurethane existing hose 20 of the invention Device is covered with a metallic coil spring 30, which do not move as a whole relative to the tube 20 therefore can, because according to the invention, the coil spring ends relative to the tube 20th
- the commercially available coil spring 30 of a Metal spring wire formed with a circular cross-section wherein the spring wire diameter is smaller than the wall thickness of the tube 20 and - if the Tube 20, unlike shown, is stretched and has no bends -
- the adjacent each other in the tube longitudinal direction coil spring sections at least almost against each other.
- the device according to the invention d. H. all parts shown in the drawing (except the tube 10) to the tube axis 20a is rotated and during the blasting process is pulled through the tube 10 or become (but in principle it would be also conceivable, the inventive device during the blasting process insert into the tube 10 and advance in this).
- spring steel wire 30a could also occur a suitable plastic wire, if the selected one Plastic against the workpiece to be treated to the desired reduction of the sliding friction leads.
- Device is therefore the flexible hose with a relatively tightly wound Coil spring sheathed, of course, a sufficient flexibility must have, so that the inventive device in the for can insert a jet treatment provided channels.
