Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a heat treatment device for forging load-bearing rings. Background Technology

[0002] A load-bearing ring is a ring-shaped structural component used to distribute and transfer loads, commonly found in fields such as machinery, construction, and aerospace. Its core function is to distribute concentrated forces to multiple support points through its ring design, thereby improving the structural load-bearing capacity and reducing the risk of localized stress concentration.

[0003] In the prior art, such as Chinese Patent No. CN223103038U, a heat treatment device for gear forging is disclosed. This device includes a frame, a control panel on the front side of the frame, a motor fixedly mounted at the lower end of the frame, a circulation assembly on the motor's output shaft, and a heating coil fixedly mounted at the rear end of the frame. A fixing assembly is mounted on the circulation assembly, and the movement trajectory of the fixing assembly is aligned with the heating coil. In this invention, the motor drives a turntable to rotate, and a protrusion lifts a sliding rod and a support plate upwards, thereby fixing the gear on the support plate into the heating coil. This facilitates heat treatment of the gear by the heating coil. When the lower end of the sliding rod moves away from the protrusion, the sliding rod and the support plate slide downwards under the gear's own weight, causing the gear on the support plate to slide away from the heating coil. This facilitates the rotation and removal of the heat-treated gear, allowing for simultaneous heat treatment of the next set of gears and removal of the heat-treated gear.

[0004] While the above solution has the advantages mentioned above, it also has disadvantages. Although it can fix multiple gears onto multiple support plates by rotating multiple sets of bidirectional screws to drive multiple sets of sliding sleeves and connecting rods, thereby fixing multiple gears onto multiple support plates, and the expansion plates can be enlarged or reduced by multiple sets of sliding sleeves and connecting rods to fix gears of different specifications, the high temperature inside the machine frame during parts heat treatment means that workers may get burned when they need to put their hands into the machine frame to rotate the bidirectional screws. Even with heat-resistant gloves, the high temperature inside the machine frame will still cause workers to feel a strong burning sensation, resulting in low worker comfort and affecting the efficiency of parts replacement. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although multiple sets of bidirectional screws can be rotated to drive multiple sets of sliding sleeves and connecting rods to fit multiple sets of expansion plates onto the inner wall of the gears, thus fixing multiple sets of gears onto multiple sets of support plates, and the expansion plates can be enlarged and reduced by multiple sets of sliding sleeves and connecting rods to fix gears of different specifications, the temperature inside the frame is high during the heat treatment of the parts. When workers need to put their hands into the frame to rotate the bidirectional screws, they may get burned. Even if they wear heat-resistant gloves, the high temperature inside the frame will still make workers feel a strong burning sensation, resulting in low worker comfort and affecting the efficiency of parts replacement.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a heat treatment device for forging a load-bearing ring, comprising: a housing, and further comprising: A heat treatment cylinder is fixedly connected to the top of the chamber. A heating coil is fixedly connected inside the heat treatment cylinder. A rotating rod is rotatably connected to the bottom of the inner wall of the chamber. A movable plate is fixedly connected to one end of the rotating rod. Multiple hollow slide rods are slidably connected in a circular array on the top of the movable plate. A ring is fixedly connected to one end of each hollow slide rod. A spring is provided on the outer surface of each hollow slide rod. A sealing disc is fixedly connected to the outer surface of each hollow slide rod near the movable plate. A hollow disk is fixedly connected to the other end of the hollow slide rod. Multiple movable strips are slidably connected in a circular array on the outer surface of the hollow disk. A pressing plate is fixedly connected to one side of each movable strip. A cooling fan is fixedly connected to one side of the chamber. An electric telescopic rod is fixedly connected to the bottom of the inner wall of the chamber. A push plate is fixedly connected to one end of the electric telescopic rod.

[0007] Preferably, multiple heat dissipation grooves are equidistantly provided on the other side of the housing, the heat treatment cylinder is connected to the housing, and the diameter of the sealing disc is equal to the inner diameter of the heat treatment cylinder.

[0008] Preferably, a motor is fixedly connected to the bottom of the housing, and the output end of the motor is fixedly connected to the other end of the rotating rod.

[0009] Preferably, one end of the second spring is fixedly connected to the top of the second ring, and the other ends of the multiple second springs are fixedly connected to the bottom of the movable plate in a circumferential array.

[0010] Preferably, a second rotating rod is rotatably connected inside the hollow slide bar, and a movable disk is fixedly connected to one end of the second rotating rod. The outer surface of the movable disk is rotatably connected to the inside of the hollow disk. The top of the movable disk has multiple straight slots arranged in a circumferential array. A round rod is rotatably connected to the bottom of the movable bar away from the abutment plate, and the outer surface of the round rod is slidably connected to the inside of the straight slots.

[0011] Preferably, the bottom of the second ring has multiple limiting holes arranged in a circumferential array, the other end of the second rotating rod is fixedly connected to the first ring, the bottom of the first ring is slidably connected to a limiting rod, and one end of the limiting rod is slidably connected inside one of the limiting holes.

[0012] Preferably, a spring is provided on the outer surface of the limiting rod, and the spring is fixedly connected to the ring and the limiting rod respectively.

[0013] Preferably, a heat dissipation pipe is fixedly connected to the top of the heat treatment cylinder, the detection end of the heat dissipation pipe extends into the interior of the heat treatment cylinder, a temperature sensor is fixedly connected to the top of the heat treatment cylinder, the temperature sensor is connected to the heat treatment cylinder, and a door is movably installed on the outer surface of the box body via a hinge.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 0. This utility model uses a controller to extend an electric telescopic rod, which moves a push plate upward, pushing a sealing disc upward. This causes the hollow slide rod, the second ring, the hollow disc, the movable strip, and the abutment plate to move upward, moving the load-bearing ring into the heat treatment cylinder. Simultaneously, the sealing disc is inserted into the heat treatment cylinder, achieving a certain degree of sealing. At the same time, the second spring is compressed. The controller then activates the heating coil to heat the load-bearing ring. The sealing disc isolates the heat treatment cylinder from the chamber, reducing heat transfer from the heat treatment cylinder to the chamber. Simultaneously, the controller activates a cooling fan to blow air onto the heat-treated load-bearing ring, cooling it appropriately. Heat from inside the chamber is then dissipated through the heat dissipation channels. This reduces the internal temperature of the chamber, decreasing the temperature felt by workers and improving their comfort, thereby increasing the efficiency of load-bearing ring replacement.

[0015] 1. This utility model allows the limiting rod to be pulled downwards by hand, disengaging it from the limiting hole and releasing the limiting effect on the first ring. Simultaneously, the first spring is stretched. At this time, rotating the first ring by hand causes the second rotating rod and the movable plate to rotate, applying a force to the round rod, causing it to slide inside the straight groove. This also applies a force to the movable strip, causing it to move the abutment plate in all directions. The bearing ring is then moved to the outer surface of the multiple abutment plates, where the abutment plates secure it. Then, the limiting rod is released, allowing it to be inserted into another limiting hole under the restoring force of the first spring, limiting the first ring. This keeps the second rotating rod, the movable plate, the round rod, the movable strip, and the abutment plate in a relatively fixed state. This allows for the fixing of bearing rings of different specifications, thereby improving the applicability of this device. Attached Figure Description

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figure 1-5As shown, this utility model provides a heat treatment device for forging a load-bearing ring, including: a housing 1, and a heat treatment cylinder 102 fixedly connected to the top of the housing 1. A heating coil 106 is fixedly connected inside the heat treatment cylinder 102. A rotating rod 2 is rotatably connected to the bottom of the inner wall of the housing 1. A movable plate 202 is fixedly connected to one end of the rotating rod 2. Multiple hollow slide rods 203 are slidably connected in a circular array on the top of the movable plate 202. A circular ring 209 is fixedly connected to one end of each hollow slide rod 203. The outer surface of the hollow slide rod 203... A spring 211 is provided on the surface. A sealing disc 205 is fixedly connected to the outer surface of the hollow slide rod 203 near the movable plate 202. A hollow disc 212 is fixedly connected to the other end of the hollow slide rod 203. Multiple movable strips 216 are slidably connected in a circular array on the outer surface of the hollow disc 212. A pressing plate 217 is fixedly connected to one side of the movable strip 216. A cooling fan 105 is fixedly connected to one side of the box body 1. An electric telescopic rod 107 is fixedly connected to the bottom of the inner wall of the box body 1. A push plate 108 is fixedly connected to one end of the electric telescopic rod 107.

[0021] Furthermore, such as Figure 1-5 As shown, multiple heat dissipation slots 101 are equidistantly provided on the other side of the housing 1. The heat treatment cylinder 102 is connected to the housing 1. The diameter of the sealing disc 205 is equal to the inner diameter of the heat treatment cylinder 102. With the above arrangement, when the sealing disc 205 is inserted into the interior of the heat treatment cylinder 102, it can achieve a certain sealing effect and reduce the heat transferred from the interior of the heat treatment cylinder 102 to the housing 1.

[0022] Furthermore, such as Figure 1-5 As shown, a motor 201 is fixedly connected to the bottom of the housing 1. The output end of the motor 201 is fixedly connected to the other end of the rotating rod 2. The motor 201 is started by the controller, so that its output shaft drives the rotating rod 2 to rotate.

[0023] Furthermore, such as Figure 1-5 As shown, one end of spring 211 is fixedly connected to the top of ring 209, and the other ends of multiple springs 211 are fixedly connected to the bottom of movable plate 202 in a circumferential array. Under the reset force of spring 211, ring 209, hollow slide bar 203 and hollow disk 212 can be moved downward.

[0024] Furthermore, such as Figure 1-5As shown, a rotating rod 204 is rotatably connected inside the hollow slide rod 203. One end of the rotating rod 204 is fixedly connected to a movable disk 213. The outer surface of the movable disk 213 is rotatably connected to the inside of the hollow disk 212. The top of the movable disk 213 has multiple straight slots 214 arranged in a circular array. A round rod 215 is rotatably connected to the bottom of the movable bar 216 away from the abutment plate 217. The outer surface of the round rod 215 is slidably connected to the inside of the straight slots 214. By rotating the ring 206 by hand, the rotating rod 204 and the movable disk 213 are rotated, and a force is applied to the round rod 215, causing the round rod 215 to slide inside the straight slots 214. A force is also applied to the movable bar 216, causing the movable bar 216 to move the abutment plate 217 to the surrounding areas. At this time, the bearing ring is moved to the outer surface of the multiple abutment plates 217, and the bearing ring is abutted and fixed by the abutment plates 217.

[0025] Furthermore, such as Figure 1-5 As shown, the bottom of the second ring 209 has multiple limiting holes 210 arranged in a circular array. The other end of the second rotating rod 204 is fixedly connected to the first ring 206. The bottom of the first ring 206 is slidably connected to a limiting rod 207. One end of the limiting rod 207 is slidably connected to the inside of one of the limiting holes 210. By pulling the limiting rod 207 down by hand, it is disengaged from the inside of the limiting hole 210, thus releasing the limitation on the first ring 206.

[0026] Furthermore, such as Figure 1-5 As shown, a spring 208 is provided on the outer surface of the limiting rod 207. The spring 208 is fixedly connected to the ring 206 and the limiting rod 207 respectively. Under the reset force of the spring 208, the limiting rod 207 can be inserted into the limiting hole 210 to limit the ring 206.

[0027] Furthermore, such as Figure 1-5 As shown, a heat dissipation pipe 103 is fixedly connected to the top of the heat treatment cylinder 102. The detection end of the heat dissipation pipe 103 extends into the interior of the heat treatment cylinder 102. A temperature sensor 104 is fixedly connected to the top of the heat treatment cylinder 102. The temperature sensor 104 is connected to the heat treatment cylinder 102. A door is installed on the outer surface of the housing 1 via a hinge. The heat dissipation pipe 103 facilitates the discharge of excess heat inside the heat treatment cylinder 102. The temperature sensor 104 facilitates the detection of the temperature inside the heat treatment cylinder 102.

[0028] Working principle: In use, by opening the door and pulling the limiting rod 207 downwards by hand, it disengages from the limiting hole 210, releasing the limiting of the ring 206. Simultaneously, the spring 208 is stretched. Then, by rotating the ring 206 by hand, the rotating rod 204 and the movable plate 213 rotate, applying a force to the round rod 215, causing it to slide inside the straight groove 214. This also applies a force to the movable strip 216, causing it to move the abutment plate 217 outwards. The bearing ring then moves to the outer surface of the abutment plates 217, which then tighten and fix it. Finally, the limiting rod 207 is released. Under the restoring force of spring 208, it is inserted into another limiting hole 210, limiting ring 206 and keeping rotating rod 204, movable plate 213, round rod 215, movable bar 216 and pressing plate 217 in a relatively fixed state. This can fix bearing rings of different specifications, thereby improving the applicability of this device. Then, the controller controls the motor 201 to start, and its output shaft drives rotating rod 2, movable plate 202, hollow slide rod 203, rotating rod 204 and hollow plate 212 to rotate, moving the bearing ring to directly below the heat treatment cylinder 102. Then, the controller controls the electric telescopic rod 107 to extend, which drives the push plate 108 to move upward. Pushing the sealing disc 205 upwards causes the hollow slide bar 203, ring 209, hollow disc 212, movable bar 216, and abutment plate 217 to move upwards, moving the bearing ring into the heat treatment cylinder 102. Simultaneously, the sealing disc 205 is inserted into the heat treatment cylinder 102, achieving a certain degree of sealing. At the same time, the spring 211 is compressed. The controller then activates the heating coil 106 to heat the bearing ring. The heating coil 106 is existing technology and will not be described in detail. The sealing disc 205 isolates the heat treatment cylinder 102 from the housing 1, reducing heat transfer from the heat treatment cylinder 102 to the housing 1. Once the bearing ring has undergone heat treatment, the controller... The electric telescopic rod 107 is retracted, causing the push plate 108 to move downwards. At this time, the thrust on the sealing disc 205 disappears. Under the restoring force of the spring 211, the ring 209, hollow slide rod 203, and ring 206 can move downwards. This process is repeated to heat-treat the next load-bearing ring. Simultaneously, the cooling fan 105 is turned on by the controller to blow air onto the heat-treated load-bearing ring, cooling it to an appropriate degree. The heat inside the housing 1 is also discharged through the heat dissipation groove 101. This reduces the temperature inside the housing 1, decreases the temperature felt by the workers, improves their comfort, and increases the efficiency of the load-bearing ring replacement.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
