Definitions

  • the invention relates first of all to a method for producing a burner plate that forms the burner plate, delimits an elongated burner chamber with longitudinal side walls and, in a central trough, a bearing for an upper part of a gas burner that has a longitudinal cooling tube from a sheet metal blank.
  • the object of the invention is to provide a method which makes it possible to produce this upper part of the burner with all of its essential components for the design of the burner chamber in a few, easy-to-perform operations from a single sheet metal blank.
  • this sheet metal is closed first on the two end faces Cut to form certain areas to form the end walls of the burner chamber, then in the middle of the width of the sheet metal blank, the trough intended for storage of the cooling tube is formed by pulling, then the two inner longitudinal areas provided on both sides of this trough, to form the burner plate, with respect to the outside, for formation of the longitudinal side walls of the burner chamber, certain longitudinal regions are bent into an inclined position and finally these two outer longitudinal regions are deformed into a position parallel to one another and are pressed against one another at their desired distance corresponding to the width of the burner chamber.
  • a burner upper part can be produced in a comparatively very simple and cost-effective manner, which is characterized by a high and easily realizable gas tightness of the burner chamber and by a technically advantageous design of the flame area.
  • outer edge zones of the two inner longitudinal regions can be integrated into one together with adjacent inner edge zones of the two outer longitudinal regions be bent towards the center of the width of the burner.
  • the front edges of the two inner longitudinal regions can also be deformed into flanges for this purpose.
  • This process step is very advantageous and can be coupled simultaneously with the pressing of the two longitudinal side walls of the upper burner part at their desired distance, that is to say with the last process step.
  • the invention also extends to a sheet metal blank for carrying it out.
  • a sheet metal blank has a length corresponding to the length of the burner and protruding on both ends in the longitudinal direction of the sheet metal blank, which can be bent to form end walls of the burner chamber and is arranged on both sides and has an extension protruding in the middle of the width of each end face and deformable for storing the cooling tube on.
  • these extensions In order to be able to produce a closed end face of the burner chamber with such extensions, these extensions have an edge which is inclined to match the oblique course of the burner plate of the burner, whereas their edge directed transversely to the longitudinal direction of the sheet metal blank runs perpendicular to this longitudinal direction and the outer edge runs parallel to this longitudinal direction .
  • the invention also extends to a method according to the invention according to the sheet metal blank produced top part of a gas burner.
  • Such an upper part formed from a single sheet metal blank can be fitted with a snug fit on the upper edges of the walls of a gas-air mixture distributor, the two outer longitudinal regions forming the side walls of the upper part and together delimiting a burner chamber, which is at the top by one of the two Inner longitudinal areas formed, with a longitudinal trough for a cooling tube and with this trough extending obliquely upwards on both sides and through which mixture outlet openings are profiled burner plate.
  • the method according to the invention enables a gas-tight connection of the end wall parts formed by the extensions of the sheet metal blank arranged on both ends with the end edges of the inner longitudinal regions of the blank forming the burner plate.
  • FIGS. 7 and 8 first show the still flat, undeformed sheet metal blank 1, on the end faces of which two lateral extensions 2 and a central projection 3 each protrude.
  • the extensions 2 later serve to form end walls delimiting the end faces of the burner chamber, the extensions 3 and the knobs 4 shown in FIG. 1 serve to hold a cooling tube 5 in a longitudinal trough 7 (FIG. 6).
  • the extensions 2 are bent approximately perpendicular to the plane of the sheet metal blank 1, as shown in FIGS. 1, 9 and 10, and at the same time the two longitudinal edges 6 of the sheet metal blank 1 are bent into a position inclined to the plane thereof.
  • the trough 7 for the cooling tube 5 is formed by pulling, the same process step also being used on both sides of the trough 7 to serve as the burner plate and to be equipped with the mixture outlet openings stretching inner longitudinal regions 8 are deformed into an inclined position with respect to the outer longitudinal regions 9.
  • the third method step comprises pre-bending those edge zones 10 of the inner longitudinal regions 8 which directly adjoin the outer longitudinal regions 9. These edge zones 10 are pre-bent with respect to the edge zones 11 of the two outer longitudinal regions 9 into a position which is initially perpendicular to these longitudinal regions 9.
  • the fourth method step comprises raising the two outer longitudinal regions 9, which thereby come to lie in a common horizontal plane, the acute angle between the inner longitudinal regions 8 and their edge zones 10 being reduced.
  • the two outer longitudinal regions 9 are bent into a position parallel to one another, but do not yet have their desired distance, but an excessively large distance.
  • the edge zones 11 of these longitudinal regions 9 are folded, namely in a width which corresponds to the width of the edge zones 10 of the two inner longitudinal regions 8.
  • the end wall of the trough 7 for the cooling tube 5 receives a collar 15 formed from the extension 3 of the sheet metal blank 1, which serves for the sealing, and the two inner longitudinal regions 8 with the mixture outlet openings each receive a joint which also serves to seal the end walls of the burner chamber 14 the end extensions 2 of the sheet metal blank 1 sealing flange 16.
  • edge zones 10 and 11 of the inner and outer longitudinal regions 8 and 9 are bent inwards together and form a solid both when they lie against each other shielding for the flame area of the burner and a secondary air duct.
