Cold balance and structure of hot pressing plate and working crossbeam of large-format hot press

Abstract

The invention relates to the technique and the structure ensuring the large-area hot press working precision. The structure comprises the hot press board, the hot reflecting materials, the heat insulation materials, the working bunton, the cycling pump and the cooling equipment. The technique are the hot reflection, the heat isolation and the cooling water cycle to realize that the cooling balancing technology replaces the hot balancing technology so as to save the heat energy and ensure the balance of the upper and the lower face boards of the working bunton, and also ensure the working precision of the hot press. And the plane degree of the pressed products is controlled in the range of 0.25mm.

Description

technical field [0001] The invention relates to a technology and structure of a large-format hot press, in particular to a technology and structure of a hot pressing plate and a working beam of a flat vulcanization hot press with functions of heat insulation and cold balance. technical background [0002] In the past large-format hot press, in order to ensure the straight quality of the pressed product, the hot pressing plate and the working beam must ensure the rigidity of the hot pressing plate under the working pressure, but due to the heating of the hot pressing plate, the upper and lower sides of the working beam The two panels are bent due to the temperature difference, resulting in the loss of the plane working accuracy of the working beam; the remedy is: usually the lower panel of the working beam is heated to balance the temperature difference between the upper and lower panels to ensure the straightness of the working beam. This method not only increases the heat c...

[0002] In the past large-format hot press, in order to ensure the straight quality of the pressed product, the hot pressing plate and the working beam must ensure the rigidity of the hot pressing plate under the working pressure, but due to the heating of the hot pressing plate, the upper and lower sides of the working beam The two panels are bent due to the temperature difference, resulting in the loss of the plane working accuracy of the working beam; the remedy is: usually the lower panel of the working beam is heated to balance the temperature difference between the upper and lower panels to ensure the straightness of the working beam. This method not only increases heat consumption, but also makes it difficult to control temperature difference balance
