They are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. They are the most widely used basic mechanical parts.

[0003] For example, the utility model with application number 202021896983.9 discloses a heat treatment furnace for improving the physical properties of fasteners. The first pulley, the second pulley, and the third pulley are beneficially provided, and the three are connected by a first belt and a second belt, so that the phase speed of the three is the same but the speed is different. When the rotating shaft is driven to rotate, different fasteners pass through the heating furnace at different speeds, thereby controlling the heating time of the fasteners. While fasteners of different sizes and shapes are heated at the same time, the heating time can be different, which makes it easier to heat treat the fasteners and improves the processing efficiency. Compared with the prior art, the heating time of the fasteners can be controlled according to their different sizes and shapes, so that the efficiency of heat treatment of the fasteners is higher.

[0004] Similar to the above application, there are still some shortcomings:

[0005] The heating furnace for heat treatment of fasteners adjusts different heating times for different fasteners, but the heating treatment only heats the outer side of the fastener drum, resulting in a limited surface area of ​​the fastener contacting the heat source, thereby reducing the processing efficiency of the fastener and failing to meet the demand for efficient fastener processing.

[0006] Therefore, a rotary heating furnace for heat treatment of metal fasteners is designed to optimize the above problems. Utility Model Content

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a rotary heating furnace for heat treatment of metal fasteners. The heating chamber, sealing cover, motor, heating tube 1, rotating shaft, net cylinder 1, pushing blade, heating tube 2, net cylinder 2, outlet and inlet are used in coordination. The motor, heating tube 1 and heating tube 2 are started. The heating tube 2 heats one side of the fastener inside the net cylinder 2, while the heating tube 1 heats the other side of the fastener outside the net cylinder 1. The motor drives the rotating shaft and the net cylinder 1 to rotate, so that the fasteners on the pushing blades rotate and are heated at the same time, which can increase the heating surface of the metal fasteners so that they are heated more comprehensively, thereby achieving the purpose of accelerating the heating speed of the metal fasteners, thereby improving the working efficiency of the rotary heating furnace for heat treatment of metal fasteners. , protrusions, swivels, balls, springs and movable rings are used in combination. The motor drives the shaft to rotate and drives the protrusions to rotate at the same time. When the protrusions rotate, they will contact the convex plates. Under the action of the convex position of the convex plates, the protrusions, the net tube 1 and the pushing leaves are pushed downward. When there is no contact with the convexity of the convex plates, under the action of the elastic force of the springs, the net tube 1 and the pushing leaves return to their original positions again. Then the net tube 1 and the pushing leaves swing up and down to make the fasteners flip on the pushing leaves, further improving the heating surface and heat treatment efficiency of the metal fasteners. Through the coordinated use of the thermal insulation layer and the protective shell, the thermal insulation layer blocks the temperature inside the heating chamber to avoid problems such as the loss of internal temperature energy. At the same time, the protective shell increases the protection of the outside of the heating chamber to improve the operating safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
