Abstract

The invention discloses a Lego hollow brick forming machine. The forming machine is characterized by comprising a base table, a hopper, a loading conveying belt, an upper cross beam, a movable cross beam I, a movable cross beam II, a machine column, a main hydraulic cylinder, an upper punch, a lower punch, a groove, a hydraulic cylinder IV, a core tool, a metal piece and a stacking table. A novelthree-stage pressing method is adopted for greatly improving the stability of high-hollowness Lego blocks, the produced blocks are small in height error, meanwhile, under the objective condition thatat the block size proportion stage, the putting amount error is high (+ / -(2 / 4)% of the block average mass), the pressure of the final pressing stage can be adjusted, and other mass parameters, such asfirmness and frost resistance, of the block can be ensured.

Description

technical field [0001] The invention relates to a Lego hollow brick molding machine and a production method. Background technique [0002] Traditional compression molding methods, such as vibratory compaction, are to distribute a single batch of granular raw materials into a closed die, use the pressure of one or two punches to press, and then push the pressed block out of the die , transported to the hardening link. The deficiency of this method is that the raw material that is distributed into die is fed through volume ratio. However, there is an error in such a feeding amount, which is at least ±2% less than the amount of raw material that should be put into the die. Even if the raw material is stable and an effective volume ratio tool is used, the error is difficult to avoid. In addition to this error, there is also a situation where raw material leaks through the gap between the closed die outer wall and the punch, resulting in error. In the stable pressing process, ...
