Abstract
A hot-forming tool for producing glass containers is provided. The tool includes a forming roller, a holder, and a heat sink. The forming roller has a forming surface. The holder receives the forming roller with the forming roller rotatably mounted on the holder. The heat sink is directly or indirectly connected to the holder. The forming roller is in thermal contact with the heat sink and the heat sink has an internal cooler so that process heat can be transferred from the forming roller to the heat sink.
Claims21
A hot-forming tool for producing glass containers, comprising:
- a forming roller with a forming surface;
- a holder having the forming roller mounted on the holder for rotation with respect to the holder;
- and
- a heat sink arranged circumferentially around the holder and directly or indirectly connected to the holder,
- wherein the forming roller and the heat sink form corresponding thermal contact surfaces on two lateral surfaces of the heat sink and on an upper side of the heat sink, and
- wherein the heat sink has a cooling device so that process heat can be transferred from the forming roller to the heat sink.
A hot-forming tool for producing glass containers, comprising:
- a holder;
- a forming roller with a forming surface, the forming roller being rotatably mounted on the holder;
- a heat sink non-rotatably connected to the holder between the forming roller and the holder so that the forming roller is in thermal contact with the heat sink;
- and
- a cooling device cooling the heat sink,
- wherein the forming roller and heat sink are configured in such a manner that corresponding contact surfaces have a surface area of at least 0.25 πR2, where R is a radius of the forming roller.
A hot-forming tool for producing glass containers, comprising:
- a forming roller with a forming surface;
- a holder, the forming roller being rotatably mounted on the holder;
- a heat sink directly or indirectly connected to the holder and in thermal contact with the forming roller;
- and
- a cooling device so that process heat can be transferred from the forming roller to the heat sink,
- wherein the heat sink comprises an upper segment and a lower segment having sealing elements arranged therebetween so as to define a portion of a coolant transmission channel through the heat sink.
A hot-forming tool for producing glass containers, comprising:
- a holder;
- a forming roller with a forming surface, the forming roller being rotatably mounted on the holder;
- a heat sink non-rotatably connected to the holder between the forming roller and the holder so that the forming roller is in thermal contact with the heat sink;
- a cooling device cooling the heat sink, wherein the heat sink is arranged around an outer circumference of the holder to define a gap therebetween;
- and
- fluid oil in the gap.
A hot-forming tool for producing glass containers, comprising:
- a holder;
- a heat sink;
- a forming roller with a forming surface;
- a bearing mounting the forming roller on the holder such that the forming roller is rotatable with respect to the holder and with respect to the heat sink and such that the forming roller is in thermal contact with the heat sink;
- and
- a cooling device in communication with the heat sink to thermally transfer process heat of the forming roller from the heat sink.
