The forming system includes a preliminary forming apparatus which preliminarily forms a metal pipe material, a forming apparatus which includes a gas supply unit which supplies gas into the preliminary-formed and heated metal pipe material to expand the metal pipe material and a main body portion to which the die is attached, and a cutting device which cuts at least a portion of the formed metal pipe. The components are arranged in a specific manner such that there is a space on either side in the first direction of the forming apparatus for other components, such as a gas supply source.
To provide a forming system and a forming method capable of improving sealing properties when a fluid is supplied to a metal pipe material. In a forming system (100), a controller (20) controls a heater (6) so as to heat end parts (14a and 14b) of a metal pipe material (14) at least before the supply of a fluid by a fluid supply unit (10). Therefore, at least before the supply of the fluid by the fluid supply unit (10), the end parts (14a and 14b) of the metal pipe material (14) are likely to be deformed by being heated by the heater (6). In such a state, the end parts (14a and 14b) of the metal pipe material (14) can be easily expanded by a pressing force generated by pressing nozzles (7 and 8) against the end parts (14a and 14b) of the metal pipe material 14, respectively. Accordingly, the nozzles (7 and 8) can secure sufficient airtightness via expanded parts (14c and 14d) of the metal pipe material 14.
Provided are: a molding device that makes it possible to obtain a molded article that has suitable characteristics; and a molding method. A control unit (70) uses a cooling medium to cool a metal pipe (80) by controlling the operation of a blow molding die (13) so that said blow molding die (13) opens after the completion of molding by the blow molding die (13) and controlling a cooling unit (90) so that the cooling medium is brought into contact with the metal pipe (80). By bringing the cooling medium into contact with the metal pipe (80) in order to perform cooling, it is possible to reduce the cooling speed as compared to when the blow molding die (13) is brought into contact with the metal pipe (80), and it becomes possible to perform firing that enhances the toughness of the metal pipe (80). In addition, by adjusting the amount of time that the cooling medium is brought into contact, the amount of the cooling medium, the temperature of the cooling medium, and the like when using the cooling medium to perform cooling, it is possible to adjust firing properties more easily than when the die is brought into contact with the metal pipe (80).

A molding apparatus capable of improving the quality of a molded article is provided. A control section (70) controls a blowing mechanism (60) so as to expand and mold a metal pipe material 14 by supplying gas into the metal pipe material (14) held between an upper mold (12) and a lower mold (11) by a pipe holding mechanism (30). The control section (70) controls a driving section (81) so as to mold a flange portion (80b) by crushing a second molded portion (14b) of the expanded metal pipe material (14) in a sub-cavity portion SC between the upper mold (12 )and the lower mold (11). In a molding apparatus (10), the control section (70) changes movement speed of a slide (82) during the molding of the flange portion (80b) by controlling a servomotor (83). Accordingly, it becomes possible to control an operation of pressing at an appropriate movement speed according to the shape or the like of the flange portion (80b). Accordingly, it is possible to improve the quality of a molded article.
An injection molding machine includes a cylinder; a screw; a rotary driving unit; a reciprocation driving unit; a pressure detector that detects a pressure of a molding material in front of the screw; a control unit that performs a first type of plasticizing process where the screw is moved backward to a predetermined position and rotated at the predetermined position to transfer the molding material forward to reserve the molding material in front of the screw, performs a first type of filling process where the screw is moved forward to inject the molding material reserved in front of the screw in the first type of plasticizing process from the cylinder to be filled in a mold unit, monitors the pressure in the first type of filling process by the pressure detector, and corrects the setting of the first type of filling process based on a monitored result.
A molding device capable of improving the quality of a molded product is provided. A control unit (70) controls a blow mechanism (60) such that it supplies gas into a metal pipe material (14) and performs expansion molding. By this means, the metal pipe material (14) is expansion-molded to a shape corresponding to a main cavity portion (MC), and a section corresponding to a flange portion (80b) of the finished product expands toward a sub-cavity portion (SC). The control unit (70) controls a drive unit (81) such that it molds the flange portion (80b) by crushing a second molded section (14b) of the expanded metal pipe material (14) using the sub-cavity portion (SC). Here, the sub-cavity portion (SC) communicates with the outside of the die during molding of the flange portion (80b), and therefore air between the inner surfaces of the sub-cavity portion (SC) and the second molded section (14b) of the metal pipe material (14) can escape to the outside of the die.

Abstract of the Disclosure A pulverized coal slurry containing 5-25 weight percent pulverized coal particles, more than 50 weight percent of the particles being minus 200 mesh, is subjected to flotation for deashing and desulfurizing treatments to thereby recover as froth cleaned coal of 15-30 weight percent concentration. This froth is dewatered into a high solids concentration coal-water slurry of more than 60 weight percent. This slurry can be transported by pipe flow as a fluid fuel or it can be burned directly in a boiler without need for dewatering. In addition, the high-degree of deashing of the slurry according to the invention enhances combustion efficiency and reduces abrasion of the boiler.
