Abstract
Disclosed are a bent-toothed sealing plate and a stamping method. A tube panel of a heating surface of a boiler is provided with the bent-toothed sealing plate, teeth are in irregular arc shapes, and a bend starting line is close to a tooth root. According to a conventional machining method, firstly, the teeth are stamped by a flat plate, and then bending is performed. Consequently, tooth deformation is large, the tooth root cannot be bent, bending angles are not easy to control, and quality requirements can only be met by taking corrective measures. The bent-toothed sealing plate comprises a steel plate (1) which is pressed into a bent plate with bending deflection of 90-180 degrees, and a group of elliptic arc notches (2) or arc toothed notches (3) are pressed at one bent end of the bent plate. The bent-toothed sealing plate is used for the tube panel of the heating surface of the boiler.
Description
Technical field
the present invention relates to a kind of band bending profile of tooth sealing plate and processing method for stamping that is used for the boiler heating surface tube panel.
Background technique
boiler heating surface tube panel has a kind of band bending shape profile of tooth sealing plate, and flute profile is irregular circular arc, plays curved line near the profile of tooth root; Processing method by routine; Promptly dull and stereotyped earlier towards profile of tooth, back press shaping die method, the profile of tooth distortion is bigger; The profile of tooth root can not bend and bend angle wayward, need take corrective action just can reach quality requirement.
Summary of the invention
the purpose of this invention is to provide a kind of ellipse arc or circular arc profile of tooth and pipe and are used effective band bending profile of tooth sealing plate and processing method for stamping.
Above-mentioned purpose realizes through following technological scheme:
a kind of band bending profile of tooth sealing plate, its composition comprises: steel plate, described steel plate is pressed into the bent plate that camber is the 90--180 degree, suppress one group of ellipse arc breach or round-arced tooth v notch v at an end of described bent plate bending.
described band bending profile of tooth sealing plate, the radian of described ellipse arc or the radian of described circular arc are the pipe diameter 42～76% that is used.
a kind of be with bending profile of tooth sealing plate processing method for stamping; Earlier flat board is pressed into 90--180 degree bent plate; Then bent plate is positioned over to adopt in the special-purpose press tool that is applicable to bent plate punching out profile of tooth on the 63--100 ton stamping press along bending line and carries out punch process; Locate first ellipse arc of punching out or circular arc cutaway earlier, next ellipse arc of travelling workpiece punching out or circular arc cutaway are located to adopt and are pressed line of position location or employing positioning plate location then.
described band bending profile of tooth sealing plate processing method for stamping, with flat board be pressed into 90 the degree bent plates.
described band bending profile of tooth sealing plate processing method for stamping, earlier flat board is pressed into 120 degree bent plates.
described band bending profile of tooth sealing plate processing method for stamping, earlier flat board is pressed into 150 degree bent plates.
[0010] beneficial effect:
1. the present invention make profile of tooth not produce distortion, have accurately guaranteed the bend angle of profile of tooth root, have saved operations such as correction and reconditioning, and quality of processing is good, and efficient is high.
The camber scope of the bent plate of
the present invention processing is big, and the diameter range of the corresponding pipe that uses is big, applied widely, and fiting effect is good.
the present invention locatees employing by line of position location or employing positioning plate location, accurate positioning, and machining accuracy is high.
the present invention adopts in the special-purpose press tool that is applicable to bent plate punching out profile of tooth and carries out punch process, and the tooth proportions of processing is accurate, and machining accuracy is high.
