Description

一种连续成型陶瓷压砖机及其生产工艺 技术领域
本发明涉及一种陶瓷压砖设备，具体地，涉及一种连续成型陶瓷压砖机及其生产工艺。
背景技术
传统的陶瓷压砖机主要有三种形式，分别为三梁四柱式、钢丝缠绕式及板框式，其生产原理皆为：下模框和下模芯位于工作台面上，运用布料栅格框，在下模芯上均匀布置陶瓷粉料，然后压机通过液压力带动上模芯向下运动，模具合模使陶瓷粉料压制成型。其完整的生产流程包括：推砖布料，模具下降、惯性加压、排气、再次压制、保压成型、卸压、顶出砖坯(开模)，然后进入下一个循环。
这些形式的陶瓷压砖机生产过程，根据生产砖坯和粉料的不同，需要进行数量不等的多次排气和加压过程，生产不同规格的砖坯，需要更换不同的模具，还可能需要不同吨位的压机、不同尺寸的工作台面。整个生产过程，运动部件重量大，所需压制力大(生产800mm×800mm瓷砖所用压机一般为38MN)，且压制完一块砖坯后压制梁需上行，等待顶砖、布料完成后才能进行下一次压制。整个生产过程能耗大、噪音大、工艺时间长。传统的陶瓷压机承受交变工作应力，机架容易出现疲劳破坏。因此，有必要提出一种新型陶瓷压砖机，解决以上问题。
本发明提出一种连续成型陶瓷压砖机及其生产工艺，能够实现陶瓷砖或者陶瓷板连续生产并柔性可调，生产效率高。
