Abstract
A controller is configured to adjust, by increasing or decreasing an amount of a lubricant mixed with the powdery material, an amount of a lubricant applied to an inner circumference of a die bore and tips, or a time to mix the lubricant to be mixed with the powdery material and the powdery material, in accordance with whether or not the molded product has defectiveness, a pressure applied to the lower punch pushing the molded product out of the die bore, a temperature of the die bore, the upper punch, or the lower punch, a temperature of the powdery material, or a humidity of the powdery material.
Claims20
A controller for a compression-molding machine configured to fill a die bore with a powdery material and to compress the powdery material by an upper punch and a lower punch to obtain a molded product, or a powdery-material feeding device configured to feed the compression-molding machine with the powdery material,
- wherein the controller is configured to adjust, by increasing or decreasing an amount of a lubricant mixed with the powdery material, an amount of a lubricant applied to an inner circumference of the die bore and punch tips, or a time to mix the lubricant to be mixed with the powdery material and the powdery material, in accordance with whether or not the molded product has a defectiveness, a pressure applied to the lower punch pushing the molded product out of the die bore, a temperature of the die bore, the upper punch, or the lower punch, a temperature of the powdery material, or a humidity of the powdery material.
A control method for a compression-molding machine configured to fill a die bore with a powdery material and to compress the powdery material by an upper punch and a lower punch to obtain a molded product, or a powdery-material feeding device configured to feed the compression-molding machine with the powdery material,
- wherein the control method comprises:
- adjusting, by increasing or decreasing an amount of a lubricant mixed with the powdery material, an amount of a lubricant applied to an inner circumference of the die bore and tips, or a time to mix the lubricant to be mixed with the powdery material and the powdery material, in accordance with whether or not the molded product has defectiveness, a pressure applied to the lower punch pushing the molded product out of the die bore, a temperature of the die bore, the upper punch, or the lower punch, a temperature of the powdery material, or a humidity of the powdery material.
A compression-molding system, comprising:
- a controller;
- and
- a compression-molding machine configured to fill a die bore with a powdery material and to compress the powdery material by an upper punch and a lower punch to obtain a molded product,
- wherein the controller is configured to adjust, by increasing or decreasing an amount of a lubricant mixed with the powdery material, an amount of a lubricant applied to an inner circumference of the die bore and the punch tips, or a time to mix the lubricant to be mixed with the powdery material and the powdery material, in accordance with whether or not the molded product has a defectiveness, a pressure applied to the lower punch pushing the molded product out of the die bore, a temperature of the die bore, the upper punch, or the lower punch, a temperature of the powdery material, or a humidity of the powdery material.
