Description

Technical Field

[0001] This utility model relates to the field of workpiece heat treatment technology, specifically a scroll plate heat treatment device. Background Technology

[0002] A scroll compressor is a compressor that can compress volumes, consisting of a fixed involute scroll and an eccentrically rotating involute scroll. The scroll compressor is formed by the interlocking of two moving and stationary scrolls with bifunctional equation profiles. During the manufacturing process of the scroll, heat treatment is required to optimize its overall performance and ensure reliability and durability under extreme operating conditions.

[0003] A search revealed a workpiece heat treatment apparatus in Chinese patent application number 202320137227.5, relating to the field of workpiece heat treatment technology. The apparatus includes a furnace body with a heating chamber and an equipment chamber arranged from top to bottom. The top of the furnace body has an opening communicating with the heating chamber, and the opening is sealed. A heating mechanism is located inside the heating chamber. A telescopic rod is located at the bottom of the equipment chamber, and a mounting platform is connected to the top of the telescopic rod. A rotating mechanism is installed on the mounting platform, which is connected to a workpiece placement platform. This apparatus heat-treats the workpiece through the heating mechanism within the heating chamber. During the heat treatment process, the rotating mechanism within the equipment chamber remains operational, causing the workpiece on the workpiece placement platform to rotate at a certain speed. This ensures uniform heating of the workpiece, resulting in a workpiece with uniform surface hardness and satisfactory performance after heat treatment, achieving excellent heat treatment results.

[0004] In the above technical solution, the workpiece that needs to be heat-treated is directly placed on the workpiece placement platform set in the heating chamber inside the furnace. During the heat treatment of the workpiece, the workpiece placement platform will be driven to rotate, thereby ensuring that the workpiece can be heated evenly. However, since there are no limiting and fixing parts on the workpiece placement platform, the workpiece is prone to sliding on the workpiece placement platform or even falling off during the rotation, which is not convenient for stable and effective heat treatment of the workpiece and is not convenient to use.

Detailed Implementation

[0022] 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.

[0023] Example

[0024] This technical solution is an improvement upon the existing patent cited in the technical background. The furnace body used for heat treatment of workpieces, and the equipment within the furnace body for heating the workpieces, are both existing known technologies. The following is a supplementary description of the furnace body and related internal auxiliary components:

[0025] The furnace body is provided with a heating chamber for heating the workpiece and an equipment chamber for installing working equipment from top to bottom. The top of the furnace body is provided with an opening that communicates with the heating chamber, and the opening is provided with a cover for sealing the entire furnace body.

[0026] The heating chamber is equipped with a heating mechanism that directly acts on the workpiece. The heating mechanism includes a flamethrower and a temperature sensor. There are at least four flamethrowers arranged opposite each other in the heating chamber to expand the heating range and ensure that the workpiece is fully heated. The temperature sensor is used to detect the temperature in the heating chamber. Depending on the required temperature of the workpiece, the flamethrower reduces or increases the flamethrower output. Specifically, the temperature sensor feeds back the detected temperature to an external controller. The controller analyzes and processes the data and controls the flamethrower to adjust the flamethrower output.

[0027] The bottom of the equipment cavity is equipped with a telescopic rod, and the top of the telescopic rod is connected to a mounting platform. A rotating mechanism is set on the mounting platform. The rotating mechanism includes a bearing, a rotating roller, a rotating motor, a main bevel gear, and a driven bevel gear. The rotating roller is rotatably connected to the mounting platform through the bearing. A rotating motor is set on one side of the rotating roller. The rotating motor is connected to the main bevel gear. The main bevel gear meshes with the driven bevel gear set on the rotating roller to realize the operation of the rotating motor and drive the rotating roller to rotate. A workpiece placement platform for placing workpieces is set at the top of the rotating roller.

[0028] During use, the furnace body can be constructed from several refractory bricks. First, the cover is opened, and then the telescopic rod moves to bring the workpiece placement platform up to the opening. At this point, the worker can place the workpiece on the workpiece placement platform. After that, the telescopic rod moves again and brings the workpiece on the workpiece placement platform into the heating chamber. Then, the cover is closed and the heating mechanism is started. The heating mechanism begins to heat treat the workpiece. It is worth noting that during the heat treatment process, the rotating mechanism remains operational, thereby driving the workpiece on the workpiece placement platform to rotate at a certain speed, so that the workpiece is fully treated by the heating mechanism. After the workpiece is heat treated, the cover is opened, the telescopic rod moves again and causes the workpiece to extend out of the opening. Finally, the worker can take the workpiece away and perform cooling treatment.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in one embodiment of this utility model, a scroll plate heat treatment device includes a base frame 1, a support spring 2, a stacking block 3, and a stacking rod 4. The base frame 1 is fixedly connected to a workpiece placement platform in the heating chamber inside the heat treatment furnace. One end of the support rod 101 on the base frame 1 is rotatably connected to the stacking rod 4, and the other end of the stacking rod 4 is rotatably connected to the stacking block 3. A support spring 2 is placed between the stacking block 3 and the base frame 1. The stacking rod 4, the stacking block 3, the support spring 2, and the base frame 1 are combined to form a limiting support and fixing frame for storing workpieces, stably supporting the workpieces inside the furnace. The workpiece is placed on the workpiece placement platform, which facilitates stable and effective heat treatment of the workpiece by the furnace body. This prevents the workpiece from sliding off the workpiece placement platform during the heat treatment process, ensuring that the workpiece is stably and effectively heat treated by the furnace body. The support rod 4 consists of a first rod body 401 and a second rod body 402 that are slidably inserted into each other. The end of the second rod body 402 is fixedly connected to a stop rod 403, which allows it to deform appropriately during use, thereby adapting to different usage requirements. This enables stable and effective support and fixation of workpieces of different sizes, improving ease of use.

[0030] like Figure 1 and Figure 2As shown, in some embodiments, the lower end of the support rod 101 is fixedly connected to the base frame 1 by screws, and the upper end of the support rod 101 is provided with a connecting groove 102 for placing the scaffolding rod 4, so that the scaffolding rod 4 can be stably connected to the support rod 101. The base frame 1 is fixedly connected to the workpiece placement platform at a designated position by bolts. The base frame 1 is stably installed, thereby providing stable and effective support and fixation for the workpiece, ensuring stable use. In addition, a first limiting seat 103 is provided at the middle part of the upper part of the base frame 1, which facilitates stable and effective limiting of the support spring 2, ensuring stable use.

[0031] like Figure 1 and Figure 3 As shown, in some embodiments, the lower end of the support spring 2 is fixedly inserted into the first limiting seat 103 on the base frame 1, and the upper end of the support spring 2 is fixedly inserted into the second limiting seat 302 provided at the lower part of the stacking block 3. The periphery of the stacking block 3 is integrally provided with a connecting ear plate 301, which facilitates the stable installation of the support spring 2 between the base frame 1 and the stacking block 3, providing stable and effective support for the stacking block 3. In the initial state, the stacking block 3 and the stacking rod 4 will apply a certain downward pressure stress to the support spring 2 under the action of gravity. Therefore, the stacking block 3 will tilt slightly downward with one end of the stacking rod 4. Since the stacking block 3 and the stacking rod 4 are not on the same horizontal plane, a slightly concave accommodating space will be formed in the middle, which facilitates the placement of the workpiece.

[0032] like Figure 1 and Figure 4 As shown, in some embodiments, one end of the first rod 401 is rotatably connected to the connecting ear plate 301 via a pivot, facilitating a stable connection between one end of the scaffolding rod 4 and the scaffolding block 3, while ensuring appropriate rotation between them during use. The insertion strip 4021 on the second rod 402 is slidably inserted into the insertion groove 4011 on the first rod 401. The sliders 4022, fixedly connected to both sides of one end of the insertion strip 4021, are slidably connected to the sliding grooves 4012 on the first rod 401. The sliding grooves 4012 on the first rod 401 and the insertion grooves 4011... 011 is through, which facilitates the stable connection of the first rod 401 and the second rod 402 together, and ensures that the second rod 402 slides smoothly on the first rod 401 through the cooperation of the plug strip 4021 and the slider 4022. This ensures that the jacking rod 4 can undergo appropriate deformation during use as the jacking block 3 moves down, thereby extending the jacking rod 4. At this time, the jacking rod 4 is tilted downward toward the jacking block 3, so that the jacking rod 4 and the jacking block 3 combine to form an inverted conical receiving space, so that the workpiece can be stably placed, so that it can be effectively heat-treated in the future.

[0033] The second rod 402 is rotatably connected to the connecting groove 102 at the upper end of the support rod 101 via a pivot, which facilitates the stable connection of one end of the scaffolding rod 4 to the support rod 101, ensuring a stable connection between the two. At the same time, it ensures that the two can rotate appropriately during use. The stop rod 403 is set at the end where the second rod 402 is connected to the support rod 101. The stop rod 403 is inclined above the scaffolding rod 4, and the stop rod 403 forms an effective barrier around the inverted cone-shaped receiving space to ensure that the workpiece is placed stably.

[0034] In use, the base frame 1 is first fixed to the workpiece placement platform with bolts to ensure the stable installation of the workpiece limiting support frame. During the workpiece placement process, the workpiece is placed directly on the stacking block 3. Under the action of gravity, the stacking block 3 moves down and pulls the first rod 401 to slide on the second rod 402. At the same time, the entire stacking rod 4 is offset downward at one end of the stacking block 3 to form an inverted cone-shaped receiving space to store the workpiece, thereby stably placing the workpiece on the limiting support frame for subsequent stable heat treatment.

[0035] When the workpiece is taken out after heat treatment, as the workpiece loses pressure on the stacking block 3, the support spring 2 pushes the stacking block 3 to move upward and reset. During the upward movement, the stacking block 3 drives the stacking rod 4 to return to its original state, thereby ensuring stable use next time.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
