Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy production equipment, and in particular to a gas heating furnace. Background Art

[0002] Aluminum alloy gas heating equipment mainly includes gas heating furnaces. Gas heating furnaces use gas (such as natural gas or liquefied petroleum gas) as fuel to heat aluminum alloy materials by burning high-temperature flames. Aluminum alloy gas heating is an efficient, environmentally friendly and energy-saving heating method, and has broad application prospects in metal processing, heat treatment, melting and other fields.

[0003] In the prior art, the gas heating furnace comprises a furnace body, a placing table, a burner, and a guide blade installed in the furnace body. The aluminum alloy parts to be heated are placed on the placing table, and the burner sprays gas to ignite them. The guide blade disperses the high-temperature heat energy in the furnace body, so that the heat in the furnace body is evenly distributed. However, in the prior art, the placing table is fixed, so that the aluminum alloy parts are also fixedly placed on the placing table. The aluminum alloy parts cannot adjust the heating surface during the heating process. Although the guide blade plays a role in dispersing the high-temperature heat energy, the temperature of the furnace body near the burner is higher, resulting in the problem of uneven heating of the aluminum alloy parts. Summary of the invention

[0004] The present invention aims to provide a gas heating furnace to solve the problem of uneven heating of aluminum alloy parts in the prior art.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A gas heating furnace comprises a furnace body burner, a guide fan blade, a placement table and a rotating table, the placement table is fixedly sleeved with a semicircular limit block, the outer periphery of the limit block is provided with a semicircular sliding groove, the rotating table is fixedly provided with a sliding rod movable in the sliding groove, the bottom of the rotating table is rotatably connected to a worm, the placement table is fixedly sleeved with a worm wheel used in conjunction with the worm, and the axis of the turbine and the axis of the limit block are coaxial.

[0007] Working principle and beneficial effects of the present invention:

[0008] In this solution, the aluminum alloy part to be heated is placed on a rotating table, and the worm is rotated. The worm drives the rotating table to rotate through the worm gear, and the sliding rod slides in the sliding groove. The rotating table drives the aluminum alloy part to rotate, so that the aluminum alloy part becomes tilted, thereby changing the posture of the aluminum alloy part during calcination, so that the larger part of the aluminum alloy part faces the burner, and the temperature of the furnace body near the burner is higher, thereby solving the problem of uneven heating of the aluminum alloy part.

[0009] Optimally, the top of the rotating platform is symmetrically equipped with limit blocks, and the aluminum alloy piece is placed between the limit blocks on both sides, thereby preventing the aluminum alloy piece from sliding when the rotating platform rotates.

[0010] Optimally, the interior of the rotating table is a hollow structure, the rotating table is symmetrically provided with through slots communicating with the interior thereof, the sliding block is slidably connected to the through slots, the rotating table is rotatably connected with a swing plate, and the swing plate abuts against the bottom of the limit blocks on both sides respectively. The swing plate rotates to alternately push the sliding blocks on both sides out of the through slots, thereby limiting the aluminum alloy part to prevent it from sliding. For example, when the aluminum alloy part tilts toward the left and lower side, the sliding block at the bottom extends to limit the aluminum alloy part, while the sliding block on the other side is separated from the high end of the aluminum alloy part, thereby preventing the sliding block from isolating / covering the high end of the aluminum alloy part, so that the high end of the alloy part is fully heated.

[0011] Optimally, a motor for driving the worm to rotate is fixedly arranged at the bottom of the rotating platform. The motor is used to drive the worm to rotate, so that the aluminum alloy part can be adjusted to rotate at any time.

[0012] Optimally, the rotating platform is fixedly provided with a heat shield for protecting the motor.

[0013] Optimally, there are two guide blades, which are distributed at the top and bottom of the furnace body. This optimization solution can make the temperature distribution in the furnace body more uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is further described in detail through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: a limit block 1, a rotating table 2, a furnace body 3, a placement table 4, a turbine 5, a worm 6, an aluminum alloy part 7, a sliding block 8, and a swing plate 9.

[0021] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0022] Embodiment 1: A gas heating furnace, such as Figure 1 As shown, it includes a furnace body 3, a burner, a guide fan blade, a placement table 4 and a rotating table 2. The burner and the guide fan are both arranged on the top of the furnace body 3, which are not shown in the figure. Figure 2 As shown, the placing table 4 is fixedly sleeved with a semicircular limit block 1, the outer periphery of the limit block 1 is provided with a semicircular sliding groove, the rotating table 2 is fixedly provided with a sliding rod (not shown in the figure) movable in the sliding groove, the bottom of the rotating table 2 is rotatably connected to a worm 6, the placing table 4 is fixedly sleeved with a worm wheel used in conjunction with the worm 6, and the axis of the turbine 5 is coaxial with the axis of the limit block 1.

[0023] like Figure 3 As shown, in this scheme, the aluminum alloy part 7 to be heated is placed on the turntable 2, and the worm 6 is rotated. The worm 6 drives the turntable 2 to rotate through the worm gear, and the sliding rod slides in the sliding groove. The turntable 2 drives the aluminum alloy part 7 to rotate, so that the aluminum alloy part 7 becomes inclined, thereby changing the posture of the aluminum alloy part 7 during calcination, so that the larger part of the aluminum alloy part 7 faces the burner, and the temperature of the furnace body 3 near the burner is higher, thereby solving the problem of uneven heating of the aluminum alloy part 7.

[0024] Example 2: Figure 4 As shown, the interior of the rotating platform 2 is a hollow structure, and the rotating platform 2 is symmetrically provided with through grooves communicating with the interior thereof, and the sliding block 8 is slidably connected to the through grooves. The rotating platform 2 is rotatably connected with a swing plate 9, and the swing plate 9 abuts against the bottom of the limiting blocks 1 on both sides. The swing plate 9 rotates to alternately push the sliding blocks 8 on both sides to extend out of the through grooves, thereby limiting the aluminum alloy part 7 to prevent it from sliding. Figure 5 As shown, for example, when the aluminum alloy part 7 tilts toward the lower left side, the sliding block 8 at the bottom extends out to limit the aluminum alloy part 7, while the sliding block 8 on the other side is separated from the high end of the aluminum alloy part 7, thereby preventing the sliding block 8 from isolating / covering the high end of the aluminum alloy part 7, so that the high end of the alloy part is fully heated.

[0025] Preferably, a spring is fixedly provided between the sliding block 8 and the through slot. When the swing plate 9 pushes the sliding block 8 out, the spring is compressed, and when the swing plate 9 is separated from the sliding block 8, the spring returns to reset the sliding block 8.

[0026] The worm 6 and the swing plate 9 can be driven by a motor.

[0027] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
