The present application relates to the technical field of composite materials, and particularly relates to a composite material oil tank and a forming method thereof. The present application provides a composite material oil tank, which comprises a plurality of barrel bodies with open ends, and the barrel bodies are connected in the axial direction; the cross section of the first end of each barrel body is a ladder structure with two ladder shapes which are symmetrical along the axis; the cross section of the second end of each barrel body is a protrusion structure with two protrusion shapes which are symmetrical along the axis and extend in the axial direction; the ladder structure and the protrusion structure are matched in shape to complete splicing; the surface of the protrusion structure close to the axis and one surface of the ladder structure are sealed and bonded by sealing glue; and the protrusion surface of the protrusion structure perpendicular to the axis and the ladder structure are bonded by structural glue. The present application provides a composite material oil tank and a forming method thereof, which can realize the forming of a large-size and lightweight composite material oil tank and improve the sealing reliability of the composite material manufacturing.

This utility model relates to the field of electromagnetic heating equipment technology, specifically disclosing an induction cooker for making potstickers, including a pot, a countertop, a first electromagnetic coil group, and a second electromagnetic coil group. The first electromagnetic coil group is located below a corresponding position on the bottom of the pot, and the second electromagnetic coil group is located below a corresponding position in the middle of the pot, surrounding the outer periphery of the first electromagnetic coil group and moving upwards. The two electromagnetic coil groups are respectively connected to independent control circuits. This structural arrangement allows for simultaneous heating of the bottom and sides of the potstickers during the potsticker-making process, improving the consistency of potsticker forming and structural adaptability. This induction cooker has a reasonable structure and is suitable for the zoned heating requirements of potsticker-type pastries.

The invention relates to the field of powder metallurgy and additive manufacturing. Specifically, the invention provides titanium carbonitride-based metal ceramic powder capable of being used for 3D printing and a preparation method of the titanium carbonitride-based metal ceramic powder. The invention further provides a binder spraying 3D printing method for preparing a titanium carbonitride-based metal ceramic formed part from the titanium carbonitride-based metal ceramic powder and the prepared titanium carbonitride-based metal ceramic formed part. The titanium carbonitride-based metal ceramic powder disclosed by the invention can be molded into a metal ceramic molded part with a complex shape and excellent mechanical properties by utilizing a binder jet printing technology. By regulating and controlling a material system and curing and sintering densification process parameters, metal ceramic materials and parts with different mechanical property intervals can be obtained so as to be matched with various properties and application requirements.
