Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to a heat treatment equipment that can be isolated. Background Technology

[0002] Because aluminum alloys have poor formability at room temperature, they are typically formed from soft blanks (such as W-state or O-state) at room temperature, or through warm / hot forming at high temperatures to manufacture medium- and high-strength aluminum alloy components. After the forming process, artificial aging treatment is required to improve the strength of the parts. In this process, due to the presence of heat treatment steps such as solution treatment and aging, heat treatment of the aluminum alloy blanks and formed parts is unavoidable.

[0003] As the variety of aluminum alloy components increases, the shapes and dimensions of billets and parts also vary, placing higher demands on the capacity of heating equipment. Existing aluminum alloy parts production lines typically use heating equipment such as air furnaces with fixed internal volumes, resulting in poor adaptability to different heating objects and high energy consumption. Different specifications of heating equipment need to be designed or purchased for different types and shapes of billets and parts, leading to a sharp increase in equipment and space costs. Therefore, it is essential to equip multi-variety aluminum alloy parts production lines with highly adaptable heating equipment with variable volumes to meet the needs of billets and parts of different shapes and sizes.

[0035] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0036] The internal volume of heating equipment such as air furnaces in existing aluminum alloy parts production lines is usually fixed, which has poor adaptability to different heating objects and high energy consumption. Different specifications of heating equipment need to be designed or purchased for different types, shapes and sizes of blanks and parts, resulting in a sharp increase in equipment and site costs. Therefore, this utility model proposes a partitionable heating device to adapt to the heat treatment needs of aluminum alloy components of different types, sizes and batches, thereby reducing the investment in production line equipment and saving site and other costs.

[0037] like Figures 1 to 3 As shown, the partitionable heating device of this embodiment includes: furnace body 100, partition 200 and heating components.

[0038] like Figure 1 As shown, the furnace body 100 in this embodiment is a horizontal furnace, and the length of the furnace body 100 extends in the left and right direction. In some other embodiments, the length of the furnace body 100 can extend in the vertical direction, that is, it is a vertical furnace, or it can be bent. The length, extension direction and shape of the furnace body 100 can be set according to different processing requirements.

[0039] The furnace body 100 in this embodiment is provided with a furnace opening 110. This embodiment has two furnace openings 110, which are respectively located at the left and right ends of the furnace body 100, to facilitate the movement of heated workpieces in and out. In some other embodiments, the furnace body 100 may be provided with one furnace opening 110.

[0040] In this embodiment, the furnace opening 110 is provided with an openable furnace door 120. During heat treatment, the furnace door 120 is closed to seal the furnace body 100. In this embodiment, both the furnace body 100 and the furnace door 120 are made of heat-insulating material to reduce heat dissipation.

[0041] The present invention has at least one partition 200. Depending on the length of the furnace body 100, multiple partitions 200 can be provided. This embodiment takes multiple partitions 200 as an example.

[0042] like Figure 2 As shown, in this embodiment, the partition 200 is detachably installed inside the furnace body 100. Multiple partitions 200 are spaced apart in the furnace body 100 in the left-right direction to divide the interior of the furnace body 100 into multiple heating chambers 130. The multiple heating chambers 130 are arranged in the left-right direction. When there is only one partition 200, two heating chambers 130 are separated. Multiple partitions 200 separate multiple heating chambers 130.

[0043] Understandably, when it is not necessary to divide the interior of the furnace body 100, the partition 200 is removed, and the furnace body 100 forms a large furnace cavity. When it is necessary to combine several heating chambers 130, a portion of the continuous partition 200 is removed to connect several heating chambers 130 and form a furnace cavity of a specific length.

[0044] The heating assembly includes at least two first heating elements 140 installed in the furnace body 100. The at least two first heating elements 140 are respectively located in at least two heating chambers 130. The number of first heating elements 140 is the same as the number of two heating chambers 130. Each first heating element 140 is used to heat the corresponding heating chamber 130. When several heating chambers 130 are interconnected to form a furnace cavity, the furnace cavity is heated by several first heating elements 140.

[0045] This invention divides the interior of the furnace body 100 into at least two heating chambers 130 using a partition 200. The partition 200 is detachably installed inside the furnace body 100, thereby enabling variable heating volume of the heating equipment. Each of the separated heating chambers 130 is equipped with a first heating element 140 for heating. For blanks and parts with different shapes and sizes, the required heating volume can be met by selecting the partition 200. It has strong applicability, and one heating equipment can be used to complete the heat treatment of different batches of parts, which helps to reduce the investment in aluminum alloy production line equipment and save space resources.

[0046] Furthermore, such as Figure 1As shown, in this embodiment, the side wall of the furnace body 100 is provided with at least one insertion port 150, and multiple insertion ports 150 are arranged at intervals in the left-right direction. The number of insertion ports 150 corresponds to the number of partitions 200, such as... Figure 2 As shown, the partition 200 is detachably inserted into the insertion port 150 to extend into the furnace body 100, thereby enabling the partition 200 to be installed and removed, and to divide the interior of the furnace body 100.

[0047] The insertion port 150 can be opened on the side or top of the furnace body 100, and the partition 200 can be slid in the horizontal direction or in the vertical direction for disassembly and assembly. In this embodiment, the insertion port 150 is located on the top of the furnace body 100.

[0048] After removing the partition 200, in order to seal the insertion port 150 and ensure the normal operation of the furnace body 100, such as... Figure 3 As shown, the partitionable heating device of this embodiment also includes at least one sealing member 300, which is used to block the insertion port 150. When the partition 200 is removed, the sealing member 300 blocks the corresponding insertion port 150.

[0049] To improve heating uniformity, such as Figure 3 As shown, the heating assembly also includes at least one second heating element 310, which is mounted on at least one sealing member 300. The second heating element 310 is used to heat the interior of the furnace body 100.

[0050] In this embodiment, by setting a second heating element 310 on the sealing component 300, the uniformity and continuity of the arrangement of each heating element are ensured when multiple heating chambers 130 are connected and heated together, thereby ensuring the temperature uniformity of different areas in the chamber.

[0051] Furthermore, each heating chamber 130 has the same length, and the first heating element 140 covers the entire inner peripheral wall of the heating chamber 130 to improve the uniformity of heating. In this case, the first heating element 140 is an electric heating wire. In some other embodiments, the first heating element 140 can be a heating air outlet, which is connected to an external hot air supply device to achieve uniform heating by blowing hot air through a fan.

[0052] In this embodiment, sealing structures are provided between the sealing component 300 and the furnace body 100, and between the sealing component 300 and the furnace body 100, respectively. This is to prevent mutual interference between the heating chambers 130 and to reduce the amount of heat dissipated outward.

[0053] Specifically, in this embodiment, the inner wall of the furnace body 100 is provided with at least one mounting groove 160 corresponding to at least one insertion port 150. The mounting groove 160 is arranged around the inner peripheral wall of the furnace body 100. The two ends of the mounting groove 160 are respectively connected to the front and rear sides of the insertion port 150. When the partition plate 200 is installed, the edge of the partition plate 200 can be embedded in the mounting groove 160 to achieve limited installation. At the same time, it also plays a guiding role in the disassembly and assembly of the partition plate 200. At this time, the mounting groove 160 acts as a guide rail.

[0054] Furthermore, such as Figure 3 As shown, the sealing member 300 in this embodiment is a ring-shaped frame structure. Specifically, the sealing member 300 in this embodiment is a rectangular frame structure. The sealing member 300 is detachably inserted into the insertion port 150 to extend into the furnace body 100. The edge of the frame structure fits into the insertion groove 160 and the insertion port 150. The inner peripheral wall of the frame structure is flush with the inner peripheral wall of the furnace body 100. This facilitates the movement of the heating element in the furnace body 100 and also facilitates the disassembly and assembly of the sealing member 300. The sealing member 300 is guided by the insertion groove 160.

[0055] In some other embodiments, the sealing member 300 only needs to seal the insertion port 150, and the sealing member 300 is a sealing plate structure.

[0056] In this embodiment, the two inner walls of the mounting groove 160 are respectively provided with a first sealing ring 161, and the two inner walls of the insertion port 150 are respectively provided with a second sealing ring 151. When the partition 200 is fitted into the mounting groove 160, the left and right sides of the partition 200 abut against the first sealing ring 161 and the second sealing ring 151 on both sides to achieve a sealed installation. When the sealing member 300 is fitted into the mounting groove 160, it also abuts against the first sealing ring 161 and the second sealing ring 151 on both sides.

[0057] In this embodiment, the partition 200 has a heat insulation layer 210 on both sides to improve the heat insulation performance between two adjacent heating chambers 130.

[0058] Each heating chamber 130 in this embodiment is equipped with a temperature control system. The temperature control system is used to control the corresponding first heating element 140 and the adjacent second heating element 310. The temperature control systems are connected in parallel and can be controlled individually or uniformly.

[0059] Regarding the usage of the partitionable heating device in this embodiment, the following three implementation methods are proposed:

[0060] Implementation Method 1:

[0061] When used for aging treatment of aluminum alloy automotive structural parts (such as B-pillars), due to the small size of the parts, a partition 200 can be installed, and only one heating chamber 130 is needed. During implementation, a feeding robot or feeding guide is used to feed the parts into the furnace body 100. For easy insertion and removal, such as... Figure 2 As shown, the heating chamber 130 near the furnace door 120 on the left and right sides can be used. After the partition 200 is installed in place, the temperature control system of the heating chamber 130 can be activated separately for heating. At this time, the other heating chambers 130 do not work, and the partition 200 plays a role in heat insulation, which can save energy costs.

[0062] Implementation Method Two:

[0063] When used for aging treatment of long rods such as aircraft stringers and ribs, as well as solution treatment of billets, the length of the heating equipment needs to be increased because the length of these components is significantly larger. In this case, the partition 200 can be moved out. Figure 3 As shown, a sealing member 300 with a second heating element 310 is inserted to fill the position of the partition 200, merging two or more heating chambers 130 into one chamber to meet the heating requirements of such parts. In practice, the partition 200 is removed, and the sealing member 300 with the second heating element 310 is moved into the position of the partition 200, ensuring it fits snugly against the left and right furnace walls, and a sealing device is used to ensure a seal. The parts are fed into the heating furnace using a feeding robot or feeding guide, and the temperature control system of the chamber occupied by the part is activated for heating. The other chambers do not need to operate. The second heating element 310 and the first heating element 140 work together to ensure a uniform arrangement of the heating elements, thereby ensuring a uniform temperature distribution throughout the entire chamber.

[0064] Implementation Method 3:

[0065] When used for mass heat treatment of small components, the partition 200 can be removed, and the sealing element 300 with the second heating element 310 can be moved in to fill the position of the partition 200, so that two or more heating chambers 130 are combined into one chamber to meet the heating requirements of a large number of parts. In practice, the partition 200 is removed, and the sealing element 300 with the second heating element 310 is moved into the position of the partition 200, so that it fits snugly against the left and right furnace walls, and a sealing device is used to ensure a seal. Parts are fed into the heating furnace in batches using feeding guides and other equipment. The temperature control system of multiple chambers is activated for heating according to the number of parts. The extra chambers can be deactivated. The second heating element 310 and the first heating element 140 work together to ensure that the heating elements are evenly distributed, thereby ensuring that the temperature is evenly distributed in all areas of the entire chamber.

[0066] This invention achieves variable heating volume of the heating equipment by using a partition 200 and a sealing element 300. Simultaneously, a parallel temperature control system enables independent and overall control of the heating temperature of each heating chamber 130. The second heating element 310 of the sealing element 300 ensures the uniformity and continuity of the heating element arrangement when multiple chambers are heated together, thereby guaranteeing temperature uniformity in different areas within the chambers. For blanks and parts with different shapes and sizes, the required heating volume can be met by selecting the partition 200 and sealing element 300, demonstrating strong applicability. A single heating device can complete the heat treatment of different batches of parts. This helps reduce investment in aluminum alloy production line equipment and saves space resources.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
