Definitions

  • the invention relates to the equipmemt to be used for the deposition of coatings on surfaces of products, and, in particular, it deals with apparatuses for hot gas spray deposition of coatings on products in the form of bodies of revolution.
  • an apparatus for hot gas spray deposition of coatings on products in the form of bodies of revolution comprising a spindle for carrying a product, a spray gun having a nozzle with an end face, means for moving the spray gun axially along, and transversely with respect to the spindle.
  • the product is installed in the spindle, a desired distance is adjusted from the end face of the nozzle and the product surface, and the product is caused to rotate.
  • a hot spray gas material to be deposited is supplied to the spray gun, and the spray gun is caused to move in an equidistant relation to the generant of the product by the means for moving the spray gun axially along, and transversely with respect to the spindle.
  • the hot gas spray coating is deposited on the product surface during single or repeated reciprocations of the spray gun.
  • the longitudinal axis of the spray gun in the above-described apparatus remains perpendicular with respect to the axis of the spindle, i.e. to the axis of rotation of the product. Therefore, with any inclined position of the generant of the body of revolution with respect to the axis of rotation, the angle between the longitudinal axis of the spray gun and the generant of the body of revolution will deviate from the right angle so as to result in a change in the range of deposition.
  • the position of the longitudinal axis of the spray gun at right angles with respect to the surface being coated is the most preferred in the hot gas spray deposition of coatings, any deviation of the axis of the spray gun from such position results in impaired quality of coating.
  • the apparatus comprises a spindle for carrying a product, a spray gun having a nozzle with an end face, a means for axially moving the spray gun with respect to the spindle, a means for moving the spray gun transversely with respect to the spindle axis, and a means for rotating the spray gun having a pivot joint.
  • the end face of the spray gun nozzle is positioned between the axis of the spindle and the pivot pin of the pivot joint of the means for rotating the spray gun so that the distance from the pivot pin of the pivot joint to the surface of the product is greater than the coating deposition range, i.e. the distance from the surface of the product to the end face of the nozzle.
  • the product is installed in the spindle, a desired coating deposition range is adjusted, and the product is caused to rotate.
  • Components for hot gas spray deposition of coating are supplied to the spray gun, and the means for axially and transversely moving the spray gun cause it move equidistantly with respect to the generant of the product.
  • the means for rotating the spray gun rotates the spray gun upon every bent of the generant of the body of revolution in such a manner that its longitudinal axis always remain perpendicular with respect to the generant.
  • the pivot pin of the' pivot joint is offset through a small distance at all portions of the product surface upon every bent of the generant to ensure a constant coating deposition range. Therefore, the path of movement of the pivot pin is more complicated than the generant of the body of revolution. This path of movement makes operation of a program control device more complicated.
  • the spray gun upon every rotation of the spray gun it applies a surplus layer of citing to a small patch lengthwise of the product in the bending zone of the generant. The larger the number of reciprocations of the spray gun along the product surface, the greater is the difference between thickness of coatings in such patches and over the rest of the product surface. It will be apparent that the kinematic system of the spray gun movement in the prior art apparatus does not allow uniform coating to be produced.
  • the invention is based on the problem of providing an apparatus for hot gas spray deposition of coatings on products in the form of bodies of revolution which can ensure uniform coating owing to a modified kinematic system.
  • an anpara- tus for hot gas spray deposition of coatings on products in the form of bodies of revolution comprising a spindle for carrying a product, a spray gun having a nozzle with an end face, a means for moving the spray gun axially along the spindle, a means for moving the spray gun transversely with respect to the axis of the spindle, and a means for rotating the spray gun having a pivot joint
  • the pivot joint of the means for rotating the spray gun is provided between the axis of the spindle and the end face of the nozzle in such a manner that the pivot pin of the pivot joint is spaced from the end face of the nozzle at a distance equal to the coating deposition range.
  • This construction of the apparatus for hot gas spray deposition of coatings to products in the form of bodies of revolution ensures the movement of the pivot pin of the pivot joint of the means for rotating the spray gun along a line following the configuration of the generant of the body of revolution so as to facilitate programming of the path of movement of the spray gun.
  • no surplus layer of coating is applied to portions of the product surface contiguous to the bending points of the generant, and uniformity of the coating layer over the entire surface of the product is ensured.
  • An apparatus for hot gas spray coating deposition on products in the form of bodies of revolution comprises a chamber 1 (Fig. 1) attached to a bed 2.
  • the bed 2 also supports a headstock 3 with a spindle A for carrying a product 5 in the form of a body of revolution, and a guide member 6 supports a tailstock 8 movable axially along the axis 7 of the spindle 4 and having a journal 9 coaxial with the axis 7.
  • a guide member 10 in the chamber 1 supports a means 11 for axially moving a spray gun 12 with respect to the axis 7 of the spindle 4, and a means 13 (Fig.
  • the means 16 for rotating the spray gun 12 has a pivot joint 17 with a pivot pin 18.
  • the spray gun 12 having a nozzle 19 with an end face 20 is mounted on the pivot joint 17 by means of mechanism 21 for linear displacement and a device 22 for emergency rotation of the spray gun 12 away from the surface of the product 5.
  • the means 16 for rotating the spray gun 12 about an axis 23 is designed for adjusting the range h of coating deposition, i.e. the distance from the surface of the product 5 to the end face 20 of the nozzle 19.
  • the apparatus for hot gas spray deposition of coatings on products in the form of bodies of revolution functions in the following manner.
  • the spray gun 12 is moved to the working position by the mechanism 14 for bringing the spray gun from the rear wall 15 to the working position and is stopped in this working position in such a manner that the axis 23 of the spray gun 12 be aligned with a plane drawn through the axis 7 of the spindle 4.
  • the spray gun 12 is then displaced by the linear displacement mechanism 21 along the axis 23 to adjust the desired coating deposition range h.
  • a program for moving the spray gun 12 with respect to the generant of the product 5 is set up, the generant being shown in Fig. 3 at 1.
  • the program sets forth the movement of the pivot pin 18 of the pivot joint 17 along a path following the configuration of the generant 1 and rotations of the spray gun 12 about the pivot pin 18 at bending points of the generant 1 in such a manner that the axis 23 of the spray gun 12 remain always perpendicular with respect to the generant 1.
  • a drive of the spindle 4 (not shown) is switched on, components of the hot gas spray coating are supplied to the spray gun 12, and drives of the means 11 for longitudinal movement, means 13 for transverse movement and rotation means 16 are switched on to move and rotate the spray gun 12 in accordance with a pre-set program.
  • the pivot pin 18 of the pivot joint 17 moves in parallel with the axis 7 (Fig.
  • the spray gun 12 moves from the position a into a position b, and the pivot pin 18 of the pivot joint 17 moves between points 0 1 and 0 2 , i.e. to the bending point of the generant 1 at an angle ⁇ .
  • the means 16 for rotating the spray gun 12 rotates the spray gun 12 from the position b to a position c, and the axis 23 of the spray gun 12 is rotated about the point 0 2 also through the angleo ⁇ .
  • the spray gun 12 is then moved at the angle ⁇ with respect to the axis 7, i.e. in parallel with the next position of the generant 1 from the position c to a position d.
  • the pivot pin 18 of the pivot joint 17 moves from the point 0 2 to a point 0 3 so as to maintain the range h.
  • the means 16 for rotating the spray gun rotates the spray gun 12 through the angle ⁇ from the position d to a position e.
  • the axis 23 of the spray gun 12 is rotated about the point 0 3 .
  • the spray gun 12 then moves in parallel with the next portion of the generant 1 from the position e to a position f.
  • the spray gun 12 is then moved and rotated in the similar manner. During the return movement of the spray gun 12 along the generant 1, its motions are repeated in the reversed order.
  • the number of reciprocations of the spray gun 12 along the generant 1 depend on the desired thickness of the coating layer on the product 5. As it can be seen from Fig. 3, the path of movement of the pivot pin 18 of the pivot joint 17 of the spray gun 12 follows the configuration of the generant 1, and all rotations of the spray gun 12 occur about bending points of the generant 1 so as to rule out application of any surplus layer of coating to the surface of the product 5 in the zones of bending points of its generant 1.
  • the emergency rotation device 22 Upon a suddent stoppage of the spindle 4 or one of the means 11, 13, 16, the emergency rotation device 22 automatically retracts the spray gun 12 to an inclined position so as to avoid application of a surplus coating to a local portion of the surface of the product 5.
  • the kinematic system for moving the spray gun 12 with respect to the pivot pin 18 of the pivot joint 17 by means of the apparatus for hot gas spray coating deposition on products in the form of bodies of revolution along a path following the configuration of the generant 1 of the body of revolution facilitates programming of movement of the spray gun 12 in carrying out deposition of hot gas spray coatings.
  • the pivot pin of rotation of the spray gun 12 is aligned with the bending points of the generant 1 during rotations of the spray gun 12, deposition of surplus coating layers in the zones of the surface of the product 5 contiguous to the bending points is avoided. This ensure unifirmity of the layer of a hot gas spray coating applied to the surface of the product and enhances product quality.
  • An apparatus for hot gas spray deposition of coatings on products in the form of bodies of revolution may be used for the deposition of coatings on bodies of revolution of simple and intricate configutation in the metallurgical, machine tool engineering and chemical industries.
