Description

Technical Field

[0001] This utility model relates to the field of mechanical workpiece processing technology, specifically a mechanical workpiece quenching device. Background Technology

[0002] Quenching is a core process in mechanical manufacturing to improve the performance of workpieces. As the front-end equipment for quenching, the heating furnace directly affects the quenching quality through its heating accuracy and efficiency. Quenching is a key step in heat treatment that changes the microstructure of materials by controlling the heating and cooling rates. Its core role is reflected in three dimensions: performance improvement, functional expansion, and life extension.

[0003] Quenching is a core step in heat treatment processes that uses a heating furnace to control the temperature of the workpiece and rapidly cool it to change the material properties. The heating furnace heats the workpiece to the austenitizing temperature, causing the carbides to dissolve. During rapid cooling, carbon atoms are fixed in the interstitial spaces of the crystal lattice, forming high-carbon martensite, which can achieve a breakthrough in the performance of mechanical workpieces.

[0004] Traditional heating furnaces often employ open or single-bearing-plane designs, lacking effective fixation of workpiece placement. This leads to workpieces being squeezed and stacked during feeding and conveying. Even if some devices are equipped with bearing structures, the bearing surfaces cannot match the placement requirements of workpieces of different sizes and shapes, easily exacerbating the stacking risk. Once workpieces are stacked, severe uneven heating occurs, hindering heat transfer, increasing energy consumption, and reducing equipment capacity. Therefore, a mechanical workpiece quenching device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mechanical workpiece quenching device that has advantages such as preventing workpieces from stacking during quenching. It solves the problem that traditional heating furnaces often adopt open or single-bearing-plane designs, which lack effective fixation of workpiece placement, causing workpieces to squeeze and stack during feeding and conveying. Even if some devices have a bearing structure, the bearing surface cannot match the placement requirements of workpieces of different sizes and shapes, which can easily exacerbate the stacking risk. Once workpieces stack, serious uneven heating problems occur, heat transfer is hindered, which not only increases energy consumption but also leads to a decrease in equipment capacity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mechanical workpiece quenching device, comprising a heating furnace, wherein a picking structure is installed inside the heating furnace, and a placing structure is installed outside the picking structure;

A turntable is fixedly installed on the output shaft of the motor. A support rod is fixedly installed on the top of the turntable. A second slider is slidably installed inside the sliding groove of the inner bottom wall of the heating furnace.

[0008] Furthermore, the placement structure includes a fixed sleeve, a fixed sleeve is fixedly installed on the outside of the support rod, a first slide rail is fixedly installed on the outside of the fixed sleeve, a slide plate is slidably installed inside the first slide rail, a swing rod is hinged to the outside of the slide plate, a limit rod passes through between every two swing rods, a limit plate is fixedly installed on the outside of the fixed sleeve, a slide rod is movably installed inside the limit plate, a second slide rail is fixedly installed on the outside of the slide rod, and a mesh tray is fixedly installed on the outside of the second slide rail.

[0009] Furthermore, the top of the support rod is rotatably connected to the second slider, and two fixing sleeves are fixedly installed on the outside of the support rod.

[0010] Furthermore, there are four first slide rails, which are located around the perimeter of the fixing sleeve.

[0011] Furthermore, a limiting groove is formed inside the limiting plate, and both the limiting rod and the sliding rod pass through the limiting groove and are slidably connected to the limiting groove.

[0012] Furthermore, the end of the swing arm near the second slide rail is also slidably connected to the second slide rail via a sliding plate.

[0013] Furthermore, there are two limiting plates, and the mesh tray is located between the two limiting plates.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This mechanical workpiece quenching device adjusts the position of the grid trays according to different quenching degrees.

[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] Please see Figure 1-5 The mechanical workpiece quenching device in this embodiment includes a heating furnace 1, a picking structure 2 installed inside the heating furnace 1, and a placement structure 3 installed outside the picking structure 2.

[0024] The take-up structure 2 includes a slide 201. The inner top wall and inner bottom wall of the heating furnace 1 are both provided with slide 201. A first slider 202 is slidably installed inside the slide 201 in the inner top wall of the heating furnace 1. A motor 203 is fixedly installed inside the first slider 202. A turntable 204 is fixedly installed on the output shaft of the motor 203. A support rod 205 is fixedly installed on the top of the turntable 204. A second slider 206 is slidably installed inside the slide 201 in the inner bottom wall of the heating furnace 1.

[0025] The placement structure 3 includes a fixed sleeve 301, a fixed sleeve 301 is fixedly installed on the outside of the support rod 205, a first slide rail 302 is fixedly installed on the outside of the fixed sleeve 301, a slide plate 303 is slidably installed inside the first slide rail 302, a swing rod 304 is hinged to the outside of the slide plate 303, a limit rod 305 passes through between every two swing rods 304, a limit plate 306 is fixedly installed on the outside of the fixed sleeve 301, a slide rod 307 is movably installed inside the limit plate 306, a second slide rail 308 is fixedly installed on the outside of the slide rod 307, and a mesh tray 309 is fixedly installed on the outside of the second slide rail 308.

[0026] exist Figure 5In the middle, multiple swing rods 304 are hinged together. When the slide plate 303 on the side closer to the first slide rail 302 moves, the multiple swing rods 304 will move synchronously, thereby achieving the effect of adjusting the position of the grid tray 309.

[0027] exist Figure 5 In the middle, slide rods 307 are installed at both the front and rear ends of the second slide rail 308. The slide rods 307 can keep the movement of the second slide rail 308 in a stable state, so that the displacement of the grid tray 309 also remains stable.

[0028] exist Figure 2 In this configuration, the two sets of placement structures 3 can be distributed at different angles outside the support rod 205, so that the upper grid tray 309 will not cause folding of the lower grid tray 309, thus affecting the quenching effect.

[0029] When implementing this procedure, follow these steps: When quenching a workpiece, pull the turntable 204 to expose the grid tray 309 to the outside of the heating furnace 1. This allows multiple workpieces to be evenly placed inside the grid trays 309. By moving the two sliding plates 303 to change the angle of the swing rod 304, the orientation of the multiple grid trays 309 can be adjusted, making it more convenient to pick up the workpieces and also increasing the production capacity of the heating furnace 1.

[0030] In summary, this mechanical workpiece quenching device, when quenching a workpiece, pulls the turntable 204, causing the first slider 202 and the second slider 206 to slide inside the slide groove 201, exposing the grid tray 309 outside the heating furnace 1. This facilitates the even placement of multiple workpieces inside the grid trays 309, preventing the workpieces from moving and stacking during quenching. When the position of the grid tray 309 needs to be adjusted according to different quenching degrees, the angle of the swing rod 304 is changed by moving the two sliding plates 303, while the limiting rod 305 moves inside the limiting plate 306, thus adjusting the position of the grid tray 309. Motor 203 drives turntable 204 to rotate, which can adjust the direction of multiple grid trays 309, making it more convenient to pick up and drop workpieces. It also increases the production capacity of heating furnace 1 and solves the problem that traditional heating furnaces 1 mostly adopt open or single bearing plane design, which lacks effective fixation of workpiece placement position, causing workpieces to squeeze and stack each other during feeding and conveying. Even if some devices are equipped with bearing structures, the bearing surface cannot match the placement requirements of workpieces of different sizes and shapes, which can easily aggravate the stacking risk. Once workpieces are stacked, serious uneven heating problems will occur, heat transfer will be hindered, which will not only increase energy consumption, but also lead to a decrease in equipment production capacity.
