Description

Technical Field

[0001] This utility model specifically relates to the field of aluminum long bar heating technology, and more specifically to an aluminum long bar hot shearing heating furnace. Background Technology

[0002] Long bar heating furnaces are industrial furnaces specifically designed for heating long bar-shaped metal materials. They are widely used in the metal processing field. They can heat long bars to the required temperature in a short time, improving production efficiency, reducing production cycles, and lowering production costs. Through the rational design of the heating element layout, furnace structure, and advanced temperature control system, the temperature distribution within the furnace is made uniform, ensuring that all parts of the long bar are heated evenly during the heating process, thereby guaranteeing the heating quality and subsequent processing performance of the long bar.

[0003] Existing heating furnaces cannot effectively achieve automatic transfer during the heating process, resulting in uneven heating of the bar stock and affecting its overall performance. With technological advancements, heating furnaces with automatic transfer have emerged. However, existing heating furnaces rely on traditional top-pushing devices to roll the bar stock inside the furnace during loading and unloading. This can lead to bar stock accumulation during unloading, preventing effective individual unloading. Therefore, existing equipment still has certain technical shortcomings.

[0004] A search revealed that Chinese Patent Publication No. CN201520295629.3 discloses an intelligent automatic conveying long aluminum rod heating furnace; it includes a support frame, on which a heating chamber is provided. The heating chamber is characterized by having multiple inclined slide rails for placing aluminum rods during heating. The higher end of each inclined slide rail has multiple upper pulleys for the aluminum rods to slide on when entering. One side of the support frame has an aluminum rod feeding device that pushes the aluminum rods onto the upper pulleys. The lower end of each inclined slide rail has multiple lower pulleys for conveying the heated aluminum rods out of the heating chamber. The upper pulleys have upper pushing devices on their sides that can lift the aluminum rods, allowing them to slide off the upper pulleys and onto the inclined slide rails. The lower end of each inclined slide rail has a lower pushing device on its side that can lift the aluminum rods, allowing them to slide off the inclined slide rails and onto the lower pulleys.

[0005] In the aforementioned patent, the inclined slide rails inside the heating furnace are equipped with an upper pushing device, a lower pushing component, and a lower pushing device. When the lower pushing component at the top of the lower pushing device moves downward, the bar stock on the inclined slide rail will roll downward in a concentrated manner, causing it to accumulate on the lower sliding wheel. However, only one bar stock can be transferred on the lower sliding wheel, and the remaining bar stock will fall off. This cannot effectively achieve the effect of transferring bar stock one by one on the lower sliding wheel, thereby reducing work efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a heating furnace for hot shearing aluminum long bars. In this structure, a first swing arm and a second swing arm are respectively arranged inside the furnace body. The second swing arm is used to transfer the bars from the feeding and conveying assembly to the inclined bar. During the downward rolling of the bars, the first swing arm effectively blocks them, preventing the bars from exceeding the support range of the inclined bar. The second swing arm feeds the bars one by one, thus effectively ensuring that the bars are automatically and neatly arranged, thereby ensuring that each bar is heated evenly during the heating process. During unloading, the up and down swing of the first swing arm effectively ensures that the heated bars are transferred to the rotating roller in sequence, thereby effectively preventing the bars from piling up during the rolling process and ensuring the efficiency of unloading; thus solving the problems of the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A heating furnace for hot shearing aluminum long bars includes a furnace body; a heating assembly is fixedly installed on the top of the furnace body; a heating tube in the heating assembly extends into the furnace body; a discharge port and a feed port are respectively opened on the two side walls of the furnace body; the discharge port and the feed port respectively achieve effective transmission of the bar material;

[0009] The discharge port is equipped with a feeding conveyor assembly, which includes a support frame fixedly installed with the furnace body. Multiple sets of seated bearings are fixedly installed on the support frame. The rotating shaft inside each set of seated bearings extends into the furnace body and is fitted with a rotating roller. The feed port is equipped with a feeding conveyor assembly, which has the same structure as the feeding conveyor assembly. The feeding and feeding conveyors are used to transport the bar stock, achieving automated operation and improving equipment efficiency.

[0010] As a further technical solution of this utility model, a sprocket is fixedly installed on the rotating shaft between each set of bearing seats, and the sprockets are connected by a chain; to ensure the stability of the bar stock during the transmission process; and to prevent the rotating roller from spinning and slipping.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In use, the bar stock is transferred through the feed port on the furnace body to the rotating roller inside the feeding and conveying assembly. The first electric push cylinder drives the second fixed rod to rotate the second rotating shaft. The second rotating shaft moves the first connecting arm and the second movable arm, causing one end of the second swing arm to flip upward, thereby transferring the bar stock on the rotating roller inside the feeding and conveying assembly to the inclined rod at the top of the support frame, thus achieving automatic placement of the bar stock.

[0019] 4. In this utility model, the first fixed rod is driven by the second electric push cylinder, which in turn drives the first rotating shaft to deflect the connecting arm and the second connecting arm, thereby adjusting the end of the first swing arm. This effectively avoids the accumulation of bar stock during downward transmission, ensures the sequential transmission of the rotating rollers, and thus effectively improves work efficiency.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 In this embodiment of the present invention, an aluminum long bar hot shearing heating furnace includes a furnace body 1; a heating component 2 is fixedly installed on the top of the furnace body 1; a heating tube in the heating component 2 extends into the interior of the furnace body 1; and a discharge port 6 and a feed port 9 are respectively opened on the two side walls of the furnace body 1.

[0031] The discharge port 6 is equipped with a feeding conveyor assembly 3; the feeding conveyor assembly 3 includes a support frame 32 fixedly installed with the furnace body 1; multiple sets of seated bearings 33 are fixedly installed on the support frame 32; the rotating shaft inside each set of seated bearings 33 extends into the furnace body 1 and is fitted with a rotating roller 31; the feed port 9 is equipped with a feeding conveyor assembly 7; the feeding conveyor assembly 7 has the same structure as the feeding conveyor assembly 3; a protective cover 30 is also fixedly installed on the side of the support frame 32 away from the furnace body 1.

[0032] A sprocket is fixedly installed on the rotating shaft between each set of bearings 33, and the sprockets are connected to each other by a chain 34.

[0033] By adopting the above technical solution, during use, the bar stock is transferred through the feed port 9 on the furnace body 1 to the rotating roller inside the feeding and conveying assembly 7. The first electric push cylinder 4 drives the second fixed rod 810 to rotate the second rotating shaft 86. The second rotating shaft 86 causes the first connecting arm 84 and the second movable arm 85 to move, so that one end of the second swing arm 83 flips upward, thereby transferring the bar stock on the rotating roller inside the feeding and conveying assembly 7 to the inclined rod 81 at the top of the support frame 80, thus achieving automatic placement of the bar stock.

[0034] A heating transmission component 8 is provided between the unloading transmission component 3 and the loading transmission component 7; the heating transmission component 8 includes multiple sets of supports 80, and diagonal rods 81 are fixedly installed on the top of the multiple sets of supports 80.

[0035] In this embodiment, the inclined rod 81 is inclined from the feeding conveyor assembly 7 to the feeding conveyor assembly 3, and the inclination angle is 20-35°.

[0036] By adopting the above technical solution, during the bar placement process, the second electric push cylinder 5 drives the first fixed rod 89 to move. The first fixed rod 89 enables the first rotating shaft 811 to drive multiple connecting arms 87 and the second connecting arm 88 to move, thereby tilting the end of the first swing rod 82 upward, thus effectively blocking the bar during the automatic placement process and preventing the bar from exceeding the support range of the inclined rod 81.

[0037] Furthermore, after the bar stock is automatically placed, the heating component 2 effectively heats the bar stock on the inclined bar 81 inside the furnace body 1 to ensure uniform heating between each bar stock. After heating, the push rod of the second electric push cylinder 5 extends to drive the first fixed rod 89 to rotate the first rotating shaft 811, so that the connecting arm 87 and the second connecting arm 88 move the end of the first swing rod 82 to the bottom of multiple rotating rollers 31, thereby transferring the heated bar stock onto the rotating rollers 31. The drive device drives the rotation of multiple rotating rollers 31 to transfer the heated bar stock to the outside of the furnace body 1 one by one.

[0038] In this embodiment, a second swing rod 83 is movably mounted on the side wall of the support frame 80 on one side of the feeding and conveying component 7 via a rotating shaft; the end of the second swing rod 83 away from the feeding and conveying component 7 is movably connected to the first connecting arm 84; the end of the first connecting arm 84 away from the second swing rod 83 is movably connected to the second movable arm 85 via a rotating shaft; the ends of multiple second movable arms 85 away from the first connecting arm 84 are fixedly mounted on the second rotating shaft 86; both ends of the second rotating shaft 86 are mounted on the support beam at the bottom of the furnace body 1 via bearing seats; and a second fixing rod 810 is also fixedly mounted on both ends of the second rotating shaft 86; the end of the second fixing rod 810 away from the second rotating shaft 86 is movably mounted to the push rod of the first electric pusher cylinder 4.

[0039] Each of the support frames 80 on one side of the material feeding and conveying assembly 3 has a first swing rod 82 movably mounted on its side wall. The end of the first swing rod 82 away from the material feeding and conveying assembly 3 is movably mounted to a connecting arm 87. The end of the connecting arm 87 away from the first swing rod 82 is movably connected to a second connecting arm 88 via a pivot. The end of the second connecting arm 88 away from the connecting arm 87 is fixedly mounted on a first pivot 811. Both ends of the first pivot 811 are mounted on the support beam at the bottom of the furnace body 1 via pivots. A first fixing rod 89 is also fixedly mounted on both ends of the first pivot 811. The end of the first fixing rod 89 away from the first pivot 811 is movably mounted to the push rod of the second electric pusher cylinder 5. The bottoms of the first electric pusher cylinder 4 and the second electric pusher cylinder 5 are movably mounted between the support beam and the first electric pusher cylinder 4.

[0040] By adopting the above technical solution, the first fixed rod 89 is driven by the second electric pusher cylinder 5, which in turn drives the first rotating shaft 811 to deflect the connecting arm 87 and the second connecting arm 88, thereby adjusting the end of the first swing rod 82. This effectively avoids the accumulation of bar stock during downward transmission, ensuring the sequential transmission of the rotating roller 31, and thus effectively improving work efficiency.

[0041] The working principle of this utility model is as follows: When in use, the bar stock is transferred to the rotating roller inside the feeding and conveying assembly 7 through the feeding port 9 on the furnace body 1. The second fixed rod 810 is driven by the first electric push cylinder 4 to rotate the second rotating shaft 86. The second rotating shaft 86 is used to move the first connecting arm 84 and the second movable arm 85, so that one end of the second swing rod 83 is flipped upward, thereby transferring the bar stock on the rotating roller inside the feeding and conveying assembly 7 to the inclined rod 81 at the top of the support frame 80, thus realizing the automatic placement of the bar stock.

[0042] During the bar placement process, the second electric push cylinder 5 drives the first fixed rod 89 to move. The first fixed rod 89 enables the first rotating shaft 811 to drive multiple connecting arms 87 and the second connecting arm 88 to move, thereby tilting the end of the first swing rod 82 upward, effectively blocking the bar during the automatic placement process and preventing the bar from exceeding the support range of the inclined rod 81.

[0043] After the bar stock is automatically placed, the heating component 2 effectively heats the bar stock on the inclined bar 81 inside the furnace body 1 to ensure uniform heating between each bar stock. After heating, the push rod of the second electric push cylinder 5 extends to drive the first fixed rod 89 to rotate the first rotating shaft 811. The connecting arm 87 and the second connecting arm 88 move the end of the first swing rod 82 to the bottom of multiple rotating rollers 31, so as to transfer the heated bar stock onto the rotating rollers 31. The driving device drives the rotation of multiple rotating rollers 31 to transfer the heated bar stock to the outside of the furnace body 1 one by one.

[0044] The second electric pusher cylinder 5 drives the first fixed rod 89, which in turn drives the first rotating shaft 811 to deflect the connecting arm 87 and the second connecting arm 88, thereby adjusting the end of the first swing rod 82. This effectively prevents the bar stock from piling up during downward transmission, ensuring that the rotating roller 31 transmits the bar stock one by one, thus effectively improving work efficiency.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
