Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a titanium alloy heating furnace with uniform temperature distribution. Background Art

[0002] Titanium alloy heating furnace is specially designed for metals with special physical and chemical properties such as titanium and titanium alloys. Titanium alloys are widely used in many fields, such as aerospace, biomedicine, etc., mainly due to their light weight, high strength and excellent corrosion resistance. However, when processing these materials, special attention should be paid to their low thermal conductivity and easy reaction with oxygen and nitrogen at high temperature. In order to meet these special needs, the design and use of titanium alloy heating furnaces are particularly important.

[0003] The existing Chinese patent (publication number CN220871440U) discloses a titanium alloy heating furnace with uniform temperature distribution. The adjustable titanium alloy heating furnace is provided with an adjustment mechanism under the fuel nozzle. The electric telescopic rod drives the movable plate to move up and down, which can drive the fuel nozzle on the movable plate to move up and down. During the heating process, the flame spraying direction in the furnace can be controlled to tilt up and down, so that higher heat can be filled in the furnace. With the setting of the motor, the contact temperature of the product is the same everywhere, the product is heated evenly, and the product processing efficiency is improved.

[0004] In the above patent, the change of the flame injection angle is achieved only by an electric telescopic rod, which limits the flexibility of flame adjustment. The electric telescopic rod can only achieve up and down tilt movement and adjustment along the up and down directions through the connection between the motor and the transmission gear. In actual applications, more complex adjustments to the angle and position of the flame may be required, including left and right or rotational adjustments to adapt to titanium alloy workpieces of different shapes and sizes and ensure uniform heating. The above patent can only achieve up and down adjustments, which may still cause local overheating problems in the furnace. Utility Model Content

[0035] Working principle:

[0036] like Figure 1-5 As shown: in the utility model, when in use, by starting the electric telescopic rod 210, the electric telescopic rod 210 touches the inner wall of the installation chamber 22 and drives the first transmission rod 25 to move downward, so that the first fixing member 24 is clamped into the clamping groove on the first transmission member, so that the connecting shaft 23 is connected to the first connecting rod, and then, by starting the motor 21, the connecting shaft 23 drives the first transmission rod 25 to rotate slightly, and the first transmission rod 25 drives the second fixing member 212 to rotate through the first rotating shaft 26 and the second transmission rod 27. The second fixing member 212 drives the first connecting member 215 and the second connecting member 217 to rotate through the connecting bead 28 and the third fixing member 213, so as to realize the transmission of the rubber paddle 29, the adjustment of the angle of the nozzle 219 and the adjustment of the air pressure in the fixed chamber 12.

[0037] The connecting bead 28 is connected to the second transmission rod 27 and the first connecting member 215 through the second fixing member 212 and the third fixing member 213. This design allows the connection to rotate freely within a certain range, similar to the structure of a universal joint, and can adapt to power transmission at different angles. When the motor 21 transmits power, the connecting bead 28 can buffer and absorb the small angle changes and displacements generated during the transmission process, thereby protecting the second transmission rod 27 and the first connecting member 215 from damage.

[0038] The sealing box 33 slides in the sliding groove and is automatically reset by the reset spring 32 to maintain the sealing performance. The rubber seal 35 is used in conjunction with the closed door 31. The rubber seal 35 is squeezed by air pressure to expand outward and fit tightly against the closed door 31 to achieve a sealing effect.
