Abstract
The present embodiments are related to a device for hot riveting by using a stud. The device may have a docking surface for the docking against a workpiece and a recess section for the shaping of a sealing head of the plastic stud. The recess section may include a cavity corresponding to the docking surface with a first depth. The device may have a compensation section arranged adjacent to the recess section, the compensation section configured to form an edge section of the plastic stud by accommodating displaced material from the sealing head of the plastic stud. The compensation section may have a second depth in relation to the docking surface, the second depth being less than the first depth.
Claims20
A device for hot riveting by using a plastic stud, the device comprising:
- a docking surface for docking against a workpiece;
- a recess section for shaping a sealing head of the stud, wherein the recess section includes a cavity corresponding to the docking surface with a first depth;
- and
- a compensation section that is arranged adjacent to the recess section, the compensation section configured to form an edge section of the stud by accommodating displaced material from the sealing head of the stud;
- wherein the compensation section has a second depth in relation to the docking surface, the second depth being less than the first depth.
A stud onto which a sealing head is shaped, the stud comprising:
- the sealing head;
- and
- an edge section arranged adjacent to the sealing head, the edge section being formed in one piece with the sealing head;
- wherein at least a partial section of the edge section a thickness of at least 0.1 mm.
A method for hot riveting using a stud, the method comprising:
- shaping a sealing head of the stud;
- and
- shaping an edge section that is made of the material of the stud that was displaced from the sealing head during the shaping of the sealing head;
- wherein the edge section is formed in one piece with the sealing head;
- and
- wherein at least a partial section of the edge section is formed with a thickness of at least 0.1 mm.
