[0001] The utility model relates to the technical field of aluminum alloy processing, and particularly relates to a chainless energy-saving continuous aluminum alloy rapid heating furnace. Background Art

[0002] Heating during the production process of aluminum alloy bars is an important technological process. It can improve the plastic deformation ability of materials, homogenize the structure, and promote phase transformation, thereby effectively improving the quality and performance of aluminum alloy bars, and it is an essential processing technology.

[0003] Current aluminum alloy processing equipment usually uses chain plates to place the bars, and drives the chain plates and the bars to move through sprockets and chains, so that the workpieces pass through the heating furnace to complete heating. However, when heating the bars, the heating furnace heats the stainless steel chain plates at the same time. And due to the large number and heavy weight of the chain plates, a large amount of heat is absorbed, resulting in low heating efficiency of the heating furnace, wasting a large amount of thermal energy, and increasing energy consumption.

[0011] In the above technical solution, the beneficial effects of a chainless energy-saving continuous aluminum alloy rapid heating furnace provided by the present utility model are as follows:

[0012] Through the provided feeding mechanism, the main sprocket drives the main chain to move, the movement of the main chain drives the synchronous movement of a plurality of feeders, the movement of the feeder drives the bar on the feeder to move. When the feeder enters the furnace body, the heaters are aligned for heating. The setting of the axial flow fan and the air duct makes the heating of the bar more uniform.

[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0022] Please refer to Figures 1 - 3 , a chainless energy-saving continuous aluminum alloy rapid heating furnace, comprising a furnace body 1, a heater and an air duct 11 are arranged on the furnace body 1, an axial flow fan is arranged in the air duct 11, and a feeding mechanism 2 is included. The feeding mechanism 2 includes two main chains 21, the two main chains 21 are arranged in parallel, and a plurality of feeders 22 are connected between the two main chains 21. The plurality of feeders 22 are arranged on the main chains 21 at equal intervals, and the main chains 21 are meshed and connected with the main sprockets. The main sprockets are driven by an external motor.

[0023] Through the arranged feeding mechanism 2, the main sprockets drive the main chains 21 to move, the movement of the main chains 21 drives the plurality of feeders 22 to move synchronously, and the movement of the feeders 22 drives the bar stock on the feeders 22 to move. When the feeders 22 enter the furnace body 1, the heaters are aligned for heating. The arrangement of the axial flow fan and the air duct 11 makes the heating of the bar stock more uniform. Compared with chain plate feeding, the materials of the plurality of feeders 22 are less, reducing the absorption of the internal heat of the furnace body 1, effectively reducing energy consumption, and the materials are lighter, reducing the driving power of the main chains 21. In addition, the arrangement of the feeders 22 can keep the bar stock stable during the movement process, and unlike the chain plate, there may be a situation where the bar stock slides. Therefore, it can cooperate with external equipment such as manipulators to realize automatic loading and unloading. Further, the feeder 22 includes a support rod 221, both ends of the support rod 221 are respectively fixedly connected to the two main chains 21, and a plurality of support frames are arranged on the support rod 221. The support frame includes two support arms 222 symmetrically arranged on the support rod 221, and a V-shaped groove 223 for placing the bar stock is formed between the two support arms 222.

[0024] Place the bar stock in the V-shaped groove 223, the main chain 21 drives the support rod 221 to move, and the movement of the support rod 221 drives the bar stock to move through the support arms 222. The V-shaped groove 223 can adapt to bar stocks of different diameters, enhancing the applicability of the device; the side of the support arm 222 in contact with the bar stock is arranged in an arc shape, so as to avoid the situation that the bar stock at the contact part is not completely heated.

[0025] A plurality of sliding rings 3 corresponding to the support frames one by one are slidably connected to the outer surface of the support rod 221. A convex block is fixedly arranged inside the sliding ring 3. The convex block is slidably connected to a groove 31 on the support rod 221, and the convex block is adapted to the groove 31. The support arm 222 is fixedly connected to the sliding ring 3.

[0026] The sliding ring 3 and the convex block are made of a material with a high coefficient of friction to prevent the sliding ring 3 from sliding during the movement of the support rod 221, which affects the support effect on the bar stock. The setting of the sliding ring 3 can be used to place bar stocks of different lengths, further improving the applicability of the device.

[0027] Furthermore, a plurality of auxiliary chains 4 are arranged between the two main chains 21. Each of the auxiliary chains 4 is arranged in parallel with the main chain 21. The support rod 221 is fixedly arranged on each of the auxiliary chains 4. The auxiliary chain 4 is meshed and connected with an auxiliary sprocket. The auxiliary chain 4 is used to assist in supporting the support rod 221 to improve the stability of the bar stock during movement.

[0028] Working principle: Place the bar stock in the V-shaped groove 223. The main sprocket drives the main chain 21 to move. The movement of the main chain 21 drives the support rod 221 to move. The movement of the support rod 221 drives the bar stock to move through the support arm 222. Compared with the traditional chain plate feeding device, the feeding device 22 of the present utility model uses less material, reduces the absorption of heat inside the furnace body 1, effectively reduces energy consumption, and the material is lighter, reducing the driving power of the main chain 21; the setting of the feeding device 22 can keep the bar stock stable during movement and there will be no situation where the bar stock slides like a chain plate. Therefore, it can cooperate with external equipment such as a manipulator to realize automatic loading and unloading; in addition, the contact area between the bar stock and the feeding device is also reduced to perform a more complete heating treatment on the bar stock.
