Description

一种热弯机Hot bending machine
本发明属于热弯设备领域,尤其涉及一种热弯机。The invention belongs to the field of hot bending equipment, and in particular relates to a hot bending machine.
现有的玻璃热弯设备多采用运输轨道,使运动的模具承载玻璃依次经过预热区、成型区以及冷却区来完成玻璃的加工。The existing glass hot bending equipment mostly adopts a transport track, so that the moving mold carrying glass sequentially passes through the preheating zone, the forming zone and the cooling zone to complete the processing of the glass.
在流水线式生产时,每个工位都需要用模具承载玻璃。然而,模具的使用寿命有一定的限度,因而模具的需求量较大;此外,设备在工作过程中,模具需反复升温、降温,影响模具使用寿命, 且升温降温过程也会浪费较大能耗;现有的热弯设备在预热区对玻璃的传热是通过加热装置给模具加热,然后间接传热给玻璃,同样的,在冷却区对玻璃的冷却也是通过冷却装置给模具冷却间接带走玻璃的热量。由于通过间接传热或间接冷却的方式效率较低,因此需要在这两区域内设置较多的工位来保证玻璃的加热与冷却,不仅浪费时间而且造成了能源的浪费。In the production of pipelines, each station needs to carry the glass with a mold. However, the service life of the mold has a certain limit, so the demand for the mold is large; in addition, during the working process, the mold needs to repeatedly heat up and cool down, which affects the service life of the mold, and the heating and cooling process also wastes a large energy consumption. The heat transfer of the existing hot bending equipment to the glass in the preheating zone is heated by the heating device, and then indirectly transferred to the glass. Similarly, the cooling of the glass in the cooling zone is also indirectly cooled by the cooling device. Take the heat of the glass. Since indirect heat transfer or indirect cooling is inefficient, it is necessary to provide more stations in the two areas to ensure heating and cooling of the glass, which not only wastes time but also wastes energy.
