Background
In the traditional glass prism hot pressing process, three stations are needed, one person is used for feeding materials, the blank is manually fed into a die body after the blank is selected to be in the rectangular direction by the lifting plate, the blank is pressed by one person, the single-machine-head hot press has the single-class daily yield of about 1.3-1.4 ten thousand, the single-machine-head hot press has the single-class daily yield of about 2.3-2.4 ten thousand, the yield is low, the material lifting station is very close to a heating furnace door, and the labor intensity is very high.
Simultaneously, the automatic retainer ring of the current hot press is used for feeding the die from top to bottom at regular time, and the motion process is as follows: after a workpiece in the porcelain box is heated and softened, the workpiece is automatically turned to a positioning shuttle groove in the furnace, the self gravity of the workpiece quickly rolls to the tail end of the shuttle groove (namely the upper part of a lower die of the die) along the gradient shuttle groove, the set automatic check ring is lowered (the workpiece is positioned and fed into the die) at the moment, the workpiece is rapidly raised within 1 second of pause, the workpiece is adjusted to enter the lower die, an upper die of the press is stepped down, the die is lifted after the profiling molding of the workpiece is completed, the workpiece is demoulded by using a special hook, the whole smooth time of the profiling period is about 5 seconds, and the automatic check ring is lowered again after 6 seconds (the set is. Through the skilled use of nearly two years, for the smart equipment promotes production efficiency once more, through the special research and communicate outward, this automatic retaining ring is urgent to be improved for the reason as follows: 1. the workpiece is taken out of the die with a probability of about 2% when the automatic check ring is rapidly lifted up after being lowered due to the inertia effect, and the workpiece needs to be moved into the die by a special hook, so that the profiling cycle is overtime; 2. even if the workpiece is smoothly inserted into the mold, the probability of about 2 percent is that the mold is difficult to be drawn due to the fact that the mold release agent or the ash slag of the porcelain box is entrained into the mold, the mold must be drawn repeatedly, and the compression cycle is overtime. Once the profiling period is overtime, the automatic retainer ring can be lowered on time due to the mechanical motion which is set repeatedly, the profiling breaks down at the moment, an operator must press down the scram to remove the fault, the condition generally affects 5-10 profiling periods, and the production efficiency is greatly affected.
