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, easily executable work steps from a single sheet metal blank.
  • a burner upper part can be produced in a comparatively simple and cost-effective manner, which is characterized by a high and easily achievable 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, together with adjacent inner edge zones of the two outer longitudinal regions, can point inward toward the center of the width of the burner Be inclined.
  • the front edges of the two inner longitudinal areas can also be deformed into flanges for this purpose.
  • This process step can be coupled very advantageously with the pressing of the two longitudinal side walls of the upper burner part against one another at their desired distance, that is to say with the last process step.
  • the invention also extends to an upper part of a gas burner produced by the method according to the invention.
  • Such an upper part formed from a single sheet metal blank is fitted onto 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 side plates.
  • 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 front 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 projections 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 its plane.
  • the depression 7 for the cooling tube 5 is formed by pulling, in the same process step also the inner longitudinal regions 8, which later serve as the burner plate and are to be provided with the mixture outlet openings, and which extend on both sides of the depression 7 Oblique position with respect to the outer longitudinal regions 9 are deformed.
  • the third method step involves 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 obtuse 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. Simultaneously with this bending of the outer longitudinal regions 9, the edge zones 11 of these longitudinal regions 9 are folded, to be precise in a width which corresponds to the width of the edge zones 10 of the two inner longitudinal regions 8.
  • the two outer longitudinal regions 9, as the longitudinal side walls of the finished burner chamber 14 are placed on the upper edges of the longitudinal side walls 13 of a mixture distribution chamber 12 and on their desired distance, which corresponds to the width of the burner chamber 14, pressed against each other, the extensions 2 each forming an end wall of the burner chamber 14 and sealing this burner chamber 14 gas-tight.
  • the end wall of the trough 7 for the cooling tube 5 receives a collar 15 formed from the projection 3 of the sheet metal blank 1, which serves as a seal, 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 jointly bent inward and form a solid, mutually adjacent shield for the flame region of the burner and a secondary air duct.
