Description

Technical Field

[0001] This utility model relates to the technical field of flywheel manufacturing, and specifically to a heat treatment device for flywheels. Background Technology

[0002] The flywheel is a key rotating energy storage component in internal combustion engines and new energy hybrid power systems. Its mechanical properties, fatigue life, and the uniformity of its microstructure after heat treatment directly affect the smoothness and reliability of the entire machine's operation. Currently, the heat treatment process for flexible flywheel discs (usually made of medium carbon steel or alloy structural steel) commonly employs induction heating followed by quenching to obtain a high-hardness surface layer and good core toughness. However, existing heat treatment equipment and processes still face numerous technical bottlenecks.

[0003] First, traditional equipment relies heavily on manual clamping and positioning, making it difficult to ensure the coaxiality of the flywheel within the induction coil. This results in uneven temperature distribution in the heating zone, easily leading to soft spots or overheated structures, severely impacting product consistency. Second, after heating, the high-temperature workpiece must be transferred to the quenching tank manually or by a robotic arm. This transfer process is not only inefficient but may also cause performance fluctuations due to oxidation or untimely cooling, and could even lead to safety accidents. Third, the oil fumes, metal vapors, and high-temperature radiation generated during induction heating lack effective collection and isolation measures. The fumes easily escape from the equipment openings, polluting the workshop environment and endangering the health of operators.

[0004] Although some automated heat treatment devices on the market have attempted to integrate robotic arms or conveyor belts, their complex structures, large footprints, high costs, and difficulty in achieving seamless integration of "heating-unloading-cooling" processes are significant challenges. Small and medium-sized manufacturing enterprises, in particular, urgently need an integrated flywheel heat treatment device that is compact, easy to operate, safe, efficient, and possesses good thermal protection and environmental protection features. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment device for flywheels to solve the above-mentioned defects caused by the prior art.

[0006] A heat treatment device for a flywheel includes a mounting cabinet, wherein the mounting cabinet is equipped with a rotating mechanism, a positioning mechanism, and a heating mechanism, wherein: The rotating mechanism includes a rodless cylinder and two rotating shafts. The rodless cylinder is vertically mounted on the back of the mounting cabinet. Its sliding block is connected to a lifting plate. A pair of racks are symmetrically connected to the left and right sides of the lifting plate. The two rotating shafts are located on the left and right sides of the lifting plate and are rotatably connected to the back of the mounting cabinet. A gear is fixedly mounted at the rear end of each rotating shaft. The gear on the same side meshes with the corresponding rack. The positioning mechanism is provided in two symmetrical arrangements. Each positioning mechanism includes a mounting plate and a dual-axis cylinder. The mounting plate is horizontally fixed on the corresponding rotating shaft and has two mounting slots symmetrically arranged in a figure-eight shape. The two dual-axis cylinders are mounted in a figure-eight shape on the lower side of the mounting plate. The piston rod ends are connected to mounting blocks. A positioning post is vertically connected to the mounting block and the positioning post is slidably fitted in the mounting slot. The heating mechanism includes two rodless cylinders and an induction heating head. Two rodless cylinders are vertically installed on the left and right sides of the mounting cabinet. A lifting plate is connected to the sliding block of the cylinder. The two lifting plates are connected by a connecting plate. The induction heating head is installed on the upper side of the connecting plate. An induction heating coil is electrically connected to the front end of the heating head. A cooling pool is provided at the bottom of the mounting cabinet.

[0007] Preferably, an air suction hood is installed on the top outer side of the installation cabinet.

[0008] Preferably, the bottom outer side of the mounting cabinet is equipped with multiple casters.

[0009] Preferably, a pair of cabinet doors are symmetrically installed on the upper front side of the mounting cabinet.

[0010] Preferably, a lighting lamp is installed on the inner top side of the mounting cabinet.

[0011] Preferably, an aerogel felt is adhered to the upper side of the mounting plate.

[0012] Preferably, the mounting block has an upward-facing photoelectric switch on its side.

[0013] Compared with the prior art, the present invention has the following advantages: 1. High-precision automatic positioning: The positioning column is driven to move laterally synchronously by the figure-eight-shaped dual-axis cylinders arranged symmetrically on the left and right sides. It can adaptively clamp flexible flywheels of different sizes and ensure that their center is accurately aligned with the axis of the induction heating coil, which greatly improves the heating uniformity and process repeatability.

[0014] 2. Integrated operation throughout the entire process: It integrates positioning, heating, flipping unloading and quenching functions. After heating is completed, no manual or external mechanical intervention is required. The rotating mechanism automatically drives the mounting plate to flip downwards by ≥90°, so that the flywheel slides directly into the cooling pool below, which greatly shortens the process cycle, avoids high-temperature oxidation, and improves the consistency of heat treatment quality.

[0015] 3. High-efficiency smoke control: The cabinet is equipped with symmetrical cabinet doors on the front side and an air suction hood connected to the exhaust system on the top, forming a negative pressure capture mode of "front baffle and top suction", which effectively prevents oil fumes and metal vapors from escaping from the front, significantly improves the working environment, and meets occupational health and environmental protection requirements.

[0016] In summary, this utility model achieves automation, precision, safety, and greening of the flywheel heat treatment process through multi-mechanism collaboration and functional integration. It is particularly suitable for flexible flywheel production scenarios with small to medium batch sizes and high consistency requirements, and has practicality and promotional value.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6 As shown, a heat treatment device for a flywheel includes a mounting cabinet 10, comprising a mounting cabinet 101, wherein the mounting cabinet 101 is provided with a rotating mechanism 20, a positioning mechanism 30, and a heating mechanism 40, wherein: The rotating mechanism 20 includes a rodless cylinder 201 and two rotating shafts 204. The rodless cylinder 201 is vertically mounted on the back of the mounting cabinet 101, and its sliding block is connected to a lifting plate 202. A pair of racks 203 are symmetrically connected to the left and right sides of the lifting plate 202. The two rotating shafts 204 are located on the left and right sides of the lifting plate 202 and are rotatably connected to the back of the mounting cabinet 101. A gear 205 is fixedly mounted at the rear end of each rotating shaft 204, and the gear 205 on the same side meshes with the corresponding rack 203. The two racks 203 move vertically through the rodless cylinder 201, thereby driving the corresponding rotating shaft 204 to rotate. When the racks 203 move downward, they drive the two mounting plates 301 to deflect downward (≥90°) and achieve automatic unloading. When the racks 203 move upward, they drive the two mounting plates 301 to deflect upward and achieve automatic reset.

[0026] The positioning mechanism 30 has two parts, arranged symmetrically from left to right. Each positioning mechanism 30 includes a mounting plate 301 and a dual-axis cylinder 302. The mounting plate 301 is horizontally fixed on the corresponding rotating shaft 204, and has two mounting grooves 301a arranged in a figure-eight shape. The two dual-axis cylinders 302 are mounted in a figure-eight shape on the lower side of the mounting plate 301, and the piston rod ends are connected to mounting blocks 303. The mounting blocks 303 are vertically connected to positioning posts 304, which slide in the mounting grooves 301a. All dual-axis cylinders 302 are arranged in a circular array, and all positioning posts 304 move laterally through the corresponding dual-axis cylinders 302, thereby driving the flexible flywheel disk 50 to be coaxially positioned directly below the induction heating coil 405.

[0027] The heating mechanism 40 includes two rodless cylinders 401 and two induction heating heads 404. Two rodless cylinders 401 are vertically mounted on the left and right sides of the mounting cabinet 101, with lifting plates 402 connected to their sliding blocks. The two lifting plates 402 are connected by a connecting plate 403. The induction heating head 404 is mounted on the upper side of the connecting plate 403, and its front end is electrically connected to an induction heating coil 405. A cooling pool 406 is provided at the lower part of the mounting cabinet 101. The induction heating head 404 moves vertically via the rodless cylinders 401, thereby driving the induction heating coil 405 to approach and heat the flexible flywheel disc 50. The heated flexible flywheel disc 50 can directly fall into the cooling pool 406 below for quenching, achieving integrated "heating-unloading-cooling" and significantly improving heat treatment efficiency and consistency.

[0028] In this embodiment, an air suction hood 102 is installed on the top outer side of the mounting cabinet 101. The air suction hood 102 is connected to an external exhaust system to promptly remove oil fumes, metal vapors, and heat generated during the heating process, thereby improving the working environment, preventing the accumulation of harmful gases, and ensuring operational safety.

[0029] In this embodiment, multiple casters 103 are installed on the outer bottom of the mounting cabinet 101. The casters 103 have both load-bearing and mobility functions, facilitating the overall transportation and positioning of the equipment, and also have a locking mechanism to ensure that the equipment remains stable and does not slip during the heat treatment process.

[0030] In this embodiment, a pair of cabinet doors 104 are symmetrically installed on the upper front side of the mounting cabinet 101. These cabinet doors 104 are used to prevent fumes from drifting away from the front of the mounting cabinet 101 when the flexible flywheel disc 50 is heated.

[0031] In this embodiment, a lighting lamp 105 is installed on the inner top of the mounting cabinet 101. The lighting lamp 105 provides uniform illumination inside the mounting cabinet 101, facilitating clear observation of the positioning, heating status, and operation of the flexible flywheel 50 in low-light conditions, thereby improving operational accuracy.

[0032] In this embodiment, an aerogel felt 305 is bonded to the upper side of the mounting plate 301. The aerogel felt 305 has an ultra-low thermal conductivity, which can effectively isolate the high temperature generated by induction heating from being conducted to precision components such as the biaxial cylinder 302, protecting the seals and control system of the biaxial cylinder 302 from heat damage and extending its service life.

[0033] In this embodiment, the mounting block 303 has an upward-facing photoelectric switch 306 on its side. The photoelectric switch 306 is used to detect whether the flexible flywheel disk 50 has been correctly placed in position. The heating program is only allowed to start when the flexible flywheel disk 50 blocks the light beam, preventing dry burning or misoperation and improving the level of automation and safety.

[0034] The working process of a heat treatment device for a flywheel is as follows: S1. Place the flexible flywheel disk 50 to be heat-treated above each positioning column 304; after the equipment is started, the dual-axis cylinder 302 synchronously drives the positioning column 304 to move laterally along the mounting groove 301a, automatically positioning the flexible flywheel disk 50 at the center position directly below the induction heating coil 405. S2. The rodless cylinder 401 drives the lifting plate 402 and the induction heating head 404 to descend, so that the induction heating coil 405 is close to the flexible flywheel 50, and then energizes it to heat it quickly and evenly. S3. After heating is completed, rodless cylinder 201 drives rack 203 downward. Through the meshing transmission between gear 205 and rack 203, the rotating shaft 204 and mounting plate 301 are driven to rotate downward ≥90° synchronously. The flexible flywheel disk 50 automatically slides into the cooling pool 406 below under the action of gravity to complete quenching.

[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
