Automatic feeding chain production quenching device

Abstract

This utility model provides an automatic feeding chain production quenching device, belonging to the technical field of chain quenching auxiliary devices. It includes a quenching feeding rack with side protective mesh plates fixedly connected to both sides. A vertical chain-hanging shaft is rotatably connected below the two side protective mesh plates. Two chain-hanging sprockets are fixedly connected to the vertical chain-hanging shaft. The traction sprockets are driven to rotate by a synchronous traction shaft to assist in pulling the chain, providing uniform feeding to the high-temperature furnace, improving feeding stability, and reducing the tension on the chain during feeding. This reduces friction between the chain and the high-temperature furnace feed inlet, preventing damage to the chain or the furnace feed inlet due to friction. It solves the problem that when chains are piled up, the lack of an auxiliary feeding mechanism during traction easily leads to twisting and knotting, and the excessive weight of the chain easily increases friction between the chain and the high-temperature furnace feed inlet, causing wear on the chain or the furnace feed inlet.

Description

Technical Field

[0001] This utility model relates to the technical field of chain quenching auxiliary devices, and in particular to an automatic feeding chain production quenching device. Background Technology

[0002] Chain quenching is a key heat treatment process designed to significantly improve the hardness, wear resistance, and strength of chains. The process mainly consists of two steps: heating and cooling. First, the chain is uniformly heated to an austenitic state in a high-temperature furnace or induction coil, causing a transformation in its internal crystal structure. Then, it is rapidly immersed in a quenching medium such as water, oil, or polymer solution for rapid cooling. This rapid cooling transforms austenite into a high-hardness martensite structure, thereby giving the chain surface and core the required mechanical properties. It is widely used in the manufacture of heavy-duty chains in mining, conveying, and transmission industries, and directly determines the chain's load capacity, fatigue life, and safety in use.

[0003] During the chain quenching process, the chain is pulled through the high-temperature furnace by the pulling mechanism. The chain located outside the high-temperature furnace feed port is piled up and pulled upward into the high-temperature furnace. The piled-up chain lacks an auxiliary feeding mechanism during the pulling process, which makes it easy to twist and knot. In addition, due to the excessive weight of the chain, it is easy to increase the friction between the chain and the high-temperature furnace feed port, resulting in wear of the chain or the high-temperature furnace feed port. Utility Model Content

[0004] This utility model provides an automatic feeding chain production quenching device to solve the problem that during the chain quenching process, the chain is pulled through the high-temperature furnace by the pulling mechanism. However, the chain located outside the high-temperature furnace inlet is piled up and pulled upward into the high-temperature furnace. The piled-up chain lacks an auxiliary feeding mechanism during the pulling process, which makes it easy for it to twist and knot. In addition, due to the excessive weight of the chain, the friction between the chain and the high-temperature furnace inlet is easily increased, leading to wear on the chain or the high-temperature furnace inlet.

[0005] This utility model provides an automatic feeding chain production quenching device, specifically including: a quenching feeding rack, with side protective mesh plates fixedly connected to both sides of the quenching feeding rack, a vertical hanging chain shaft rotatably connected between the two side protective mesh plates, two hanging chain sprockets fixedly connected to the vertical hanging chain shaft, a feeding drive motor fixedly connected to the upper end of the quenching feeding rack by bolts, the shaft of the feeding drive motor being connected to the input shaft of a feeding reducer, the feeding reducer being fixedly connected to the upper end of the quenching feeding rack, the output shaft of the feeding reducer being connected to and driving a synchronous traction shaft through chain drive, the synchronous traction shaft being rotatably connected to the upper end of the quenching feeding rack through bearings, two traction sprockets fixedly connected to the synchronous traction shaft, and a reversing support shaft located inside the quenching feeding rack, with two reversing sprockets rotatably connected to the reversing support shaft.

[0006] Furthermore, a feeder support is fixedly connected to the lower front of the quenching feeder, and a slag baffle is fixedly connected inside the feeder support.

[0007] Furthermore, a rectangular height adjustment frame is provided in the middle of the side protective mesh plate, and an inner groove is provided on the inner wall of the height adjustment frame.

[0008] Furthermore, the outer surface of the side protective mesh plate is rotatably connected to an adjusting screw via a bearing, and a screw handle is fixedly connected to the upper end of the adjusting screw.

[0009] Furthermore, a reversing adjustment slider is fixedly connected to each end of the reversing support shaft, and the reversing adjustment slider is located inside the height adjustment frame.

[0010] Furthermore, the reversing adjustment slider is externally fixedly connected to a guide bar, which is slidably connected inside the slide groove within the frame.

[0011] Furthermore, a spiral push block is welded to the outer surface of the reversing adjustment slider, and the spiral push block has a screw hole at its center that is spirally connected to the adjusting screw.

[0012] This utility model provides an automatic feeding chain production quenching device, which has the following beneficial effects: This utility model provides a chain auxiliary feeding mechanism for chain quenching, which is set at the feed inlet of a high-temperature furnace. During the chain quenching process, the chain passes through the hanging sprocket, traction sprocket, and reversing sprocket before entering the high-temperature furnace. During this conveying process, the chain is fully stretched and extended, avoiding chain tangling and knotting. At the same time, through the cooperation of the feeding drive motor and the feeding reducer, the synchronous traction shaft is driven to rotate, which in turn drives the traction sprocket to rotate, providing auxiliary traction to the chain and providing uniform feeding to the high-temperature furnace, improving feeding stability. It also reduces the tension on the chain during feeding and reduces the friction between the chain and the feed inlet of the high-temperature furnace, avoiding damage to the chain or the feed inlet of the high-temperature furnace due to friction.

[0013] Furthermore, by setting up a reversing support shaft, the chain between the high-temperature furnace feed inlet and the traction sprocket is bypassed by the reversing sprocket, which supports and reverses the chain, making the chain feeding direction nearly perpendicular to the high-temperature furnace feed inlet. This reduces the friction between the chain and the inner wall of the high-temperature furnace. The reversing support shaft has a lifting and adjusting function, which can adjust the chain feeding angle according to the different heights of the high-temperature furnace feed inlet, thus improving the applicability of the device.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an automatic feeding chain production quenching device, comprising: a quenching feeding rack 1, with side protective mesh plates 2 fixedly connected to both sides of the quenching feeding rack 1, and a vertical hanging chain shaft 8 rotatably connected below the two side protective mesh plates 2, with two hanging chain sprockets 801 fixedly connected to the vertical hanging chain shaft 8, a feeding drive motor 4 fixedly connected to the upper end of the quenching feeding rack 1 by bolts, the shaft of the feeding drive motor 4 being connected to the input shaft of a feeding reducer 5, the feeding reducer 5 being fixedly connected to the upper end of the quenching feeding rack 1, and the output shaft of the feeding reducer 5 being connected and driven synchronously via chain drive. The guide shaft 6 and the synchronous traction shaft 6 are rotatably connected to the upper end of the quenching loading rack 1 via bearings. Two traction sprockets 601 are fixedly connected to the synchronous traction shaft 6. The reversing support shaft 7 is located inside the quenching loading rack 1. Two reversing sprockets 701 are rotatably connected to the reversing support shaft 7. During the quenching process of the chain, the chain passes around the hanging sprocket 801, the traction sprocket 601, and the reversing sprocket 701 before entering the high-temperature furnace. During this conveying process, the chain is fully stretched and extended to avoid chain entanglement and knotting. When the chain is lifted to the height of the hanging sprocket 801, it is vertically stretched to prevent the chain from getting entangled.

[0020] In this embodiment, a feeder support 101 is fixedly connected to the lower front of the quenching feeder 1, and a slag baffle 102 is fixedly connected inside the feeder support 101. The slag baffle 102 can intercept and collect the waste slag falling during the quenching process. A rectangular height adjustment frame 201 is provided in the middle of the side protective mesh plate 2, and an inner sliding groove 202 is provided on the inner wall of the height adjustment frame 201. The side protective mesh plate 2 prevents the waste slag from splashing outward during the quenching process and prevents the chain from breaking or shattering during the feeding process, which could cause damage to surrounding personnel or the environment.

[0021] In Example 2, based on Example 1, an adjusting screw 3 is rotatably connected to the outer surface of the side protective mesh plate 2 via bearings. A screw handle 301 is fixedly connected to the upper end of the adjusting screw 3. A reversing adjustment slider 702 is fixedly connected to each end of the reversing support shaft 7. The reversing adjustment slider 702 is located inside the height adjustment frame 201. A guide strip 703 is fixedly connected to the outside of the reversing adjustment slider 702. The guide strip 703 is slidably connected inside the slide groove 202 within the frame. A spiral push block 704 is welded to the outer surface of the reversing adjustment slider 702. The spiral push block 704 has a screw hole at its center that is spirally connected to the adjusting screw 3. For high-temperature furnace feed inlets with different opening heights, it is necessary to... Adjust the height of the reversing support shaft 7 so that the chain remains perpendicular to the feed inlet of the high-temperature furnace when it passes the reversing sprocket 701, thereby reducing the friction between the chain and the inner wall of the feed inlet of the high-temperature furnace. In specific operation, the screw handle 301 at the end of the adjusting screw 3 on both sides can be manually rotated. Through the screw transmission between the adjusting screw 3 and the spiral push block 704, the reversing adjustment slider 702 is pushed to slide along the height adjustment frame 201, thereby adjusting the height of the reversing support shaft 7. This allows the chain between the feed inlet of the high-temperature furnace and the traction sprocket 601 to bypass the reversing sprocket 701, supporting and reversing the chain. This makes the chain feeding direction nearly perpendicular to the feed inlet of the high-temperature furnace, reducing the friction between the chain and the inner wall of the high-temperature furnace.

[0022] The working principle of this embodiment is as follows: First, the unquenched chain is stored below the quenching loading rack 1. The chain is then passed successively around the chain sprocket 801, the traction sprocket 601, and the reversing sprocket 701, and then extended into the high-temperature furnace inlet. At the high-temperature furnace outlet, an external traction mechanism pulls the heated chain and performs corresponding cooling operations. During the quenching process, the loading drive motor 4 is started, which drives the loading reducer 5, which in turn drives the synchronous... The traction shaft 6 rotates, and the traction sprocket 601 rotates to assist in pulling the chain. During this process, the chain is stretched by the pull to avoid entanglement. After the chain passes the limit of the reversing sprocket 701, it enters the feed inlet of the high-temperature furnace. This allows the chain between the feed inlet of the high-temperature furnace and the traction sprocket 601 to bypass the reversing sprocket 701, supporting and reversing the chain. This makes the chain feeding direction nearly perpendicular to the feed inlet of the high-temperature furnace, reducing the friction between the chain and the inner wall of the high-temperature furnace, and achieving stable auxiliary feeding of the chain.
