Description

Technical Field

[0001] This utility model belongs to the field of spring production technology, and in particular relates to a heat treatment equipment for carbon spring production. Background Technology

[0002] Carbon springs, with their combination of high strength, high elastic modulus, excellent fatigue resistance and corrosion resistance, occupy an irreplaceable position in the industrial field. In the field of mechanical manufacturing, they are often used as shock absorbers and transmission buffers in heavy equipment. They need to withstand high-frequency load impacts for a long time, which places strict requirements on their structural stability and mechanical performance durability. The heat treatment process, as the core link that determines the final performance of carbon springs, has extremely high requirements on the workpiece positioning accuracy, specification adaptability and processing uniformity of the equipment.

[0003] Chinese patent application CN219470126U discloses a spring heat treatment device, relating to the field of spring production technology. The device includes a heat treatment chamber with a first motor fixedly connected to its bottom. The output end of the first motor passes through the heat treatment chamber and is rotatably connected to it. This application utilizes the coordinated arrangement of a mist exhaust pipe, a second motor, fan blades, and connecting rods. While the user water-cools the heat-treated spring using a cooling device, the user simultaneously activates the second motor. The second motor drives the fan blades to rotate, expelling the high-temperature water vapor generated during cooling through the mist exhaust pipe. This avoids the problem of existing spring heat treatment devices lacking a device for removing water vapor generated during cooling, which can easily cause burns to users when removing the springs, making it inconvenient for them.

[0004] While this patented device utilizes a structure including a mist exhaust pipe, a second motor, and fan blades to promptly remove the high-temperature water vapor generated during cooling, thus avoiding the risk of burns when users remove the springs, its use of multiple fixed-size positioning pins makes it difficult for springs with smaller diameters to fit smoothly into the pins, while springs with larger diameters cannot be stably fixed on the pins, making them prone to tilting or shifting during heating, thus affecting the heat treatment effect. Furthermore, the device uses multiple independent heating sleeves to heat the springs separately, each requiring an independent heating element, resulting in a complex structure and high manufacturing costs.

[0005] To address these issues, we provide a heat treatment apparatus for the production of carbon springs. Utility Model Content

[0006] The purpose of this utility model is to provide a heat treatment device for carbon spring production. By combining the limiting component and the rotating component, it solves the problem that the existing heat treatment device for carbon spring production cannot effectively fix springs of different sizes and has high manufacturing costs.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a heat treatment device for carbon spring production, comprising a housing, a limiting assembly disposed within the inner cavity of the housing, a rotating assembly disposed at the bottom of the limiting assembly, and a switching plate comprising a bottom rotatably connected to the housing, a limiting post detachably connected to the top of the switching plate, a guide rod slidably connected to the inner cavity of the limiting post, a tension spring disposed on the surface of the guide rod, one side of the tension spring being fixedly connected to the limiting post, and a limiting plate disposed on the other side of the tension spring, one side of the limiting plate being fixedly connected to the guide rod, and a connecting rod movably connected to the bottom of the limiting plate, the other end of the connecting rod being detachable. The device is equipped with a pull rod, which is slidably connected to the limiting posts on both sides. The bottom of the pull rod passes through the inner cavity of the limiting post and extends to the bottom of the switching plate. The limiting posts are connected to the switching plate by bolts. There are six limiting posts, which can simultaneously limit and fix multiple workpieces. Each limiting post is equipped with two limiting plates, which can apply clamping force from both sides of the workpiece simultaneously to form a symmetrical limiting structure. This ensures that the workpiece is subjected to balanced force during processing and reduces the possible deviation caused by unilateral limiting. A pull plate is fixedly connected to the bottom of the pull rod, which increases the contact area between the hand and the pull rod. The operator can drive the pull rod more effortlessly by pulling the pull plate.

[0009] The present invention is further configured such that the rotating assembly includes a motor, the bottom of the motor is fixedly connected to the housing, a turntable is fixedly connected to the top of the motor, a pin is fixedly connected to one side of the top of the turntable, an arc plate is provided on the other side of the pin, the bottom of the arc plate is fixedly connected to the turntable, a grooved wheel is slidably connected to one side of the arc plate, a rotating rod is fixedly connected to the inner side of the grooved wheel, the bottom of the rotating rod is rotatably connected to the housing, and the top of the rotating rod is fixedly connected to the switching plate. The intermittent transmission between the grooved wheel and the pin enables each workpiece to obtain a consistent heating time, effectively ensuring the performance consistency of different workpieces after heat treatment, and the arc plate can lock the position of the grooved wheel.

[0010] The present invention is further configured such that a ventilation pipe is provided at the top of the limiting post, and the bottom of the ventilation pipe is fixedly connected to the box body. The ventilation pipe is used to exhaust the gas inside the box body to prevent hot air from staying inside the box body.

[0011] The present invention is further configured such that a sliding rod is fixedly connected to the bottom of the inner cavity of the limiting post, and the surface of the sliding rod is slidably connected to the pull rod. The sliding rod can restrict the movement of the pull rod and improve its stability during operation.

[0012] The present invention is further configured such that a limiting groove is formed in the inner cavity of the limiting post, and the inner cavity of the limiting groove is slidably connected to the guide rod. The limiting groove can limit the range of motion of the guide rod and prevent it from leaving the inner cavity of the limiting post.

[0013] The present invention is further configured such that a sliding groove is provided in the inner cavity of the box, and a support plate is slidably connected to the inner cavity of the sliding groove. The top of the support plate is fixedly connected to the switching plate. There are four support plates, which are evenly distributed at the bottom of the switching plate, so as to provide stable support for it.

[0014] The present invention is further configured such that a heating block is fixedly connected to one side of the inner cavity of the box, and a heating tube is fixedly connected to the inner cavity of the heating block. The heating tube is multiple and arranged in an array in the inner cavity of the heating block, which can fully heat different parts of the workpiece.

[0015] The present invention is further configured such that a nozzle is provided on one side of the limiting post, the surface of the nozzle is fixedly connected to the housing, and the nozzle is used to spray and cool the workpiece after heating.

[0016] The present invention has the following beneficial effects.

[0017] 1. The limiting assembly of this utility model moves the connecting rod by pulling the pull rod, which in turn pulls the limiting plate, causing the guide rod to slide and compress the tension spring. This causes the limiting plate to contract inward, and after the spring is sleeved on the limiting post, the pull rod is released. The limiting plate expands outward by the elastic force of the tension spring, thereby accommodating the inner rings of carbon springs of different diameters and achieving stable limiting of the carbon spring. The limiting plate provides radial support from inside the carbon spring, ensuring that the carbon spring maintains the correct positioning relative to the heating element during the heat treatment process. This effectively prevents problems such as uneven heating, deformation, and low heating efficiency caused by the tilting or displacement of the carbon spring, thus ensuring the consistency and reliability of the product's heat treatment quality.

[0018] 2. The rotating assembly of this utility model, through the cooperation of the grooved wheel and the pin, allows multiple stations on the switching plate to rotate sequentially to the same heating station. There is no need to configure a separate heating assembly for each station. Only one heating station is needed to meet the heating requirements of all carbon springs, which simplifies the overall structure of the equipment and reduces the amount of heating-related components. This not only reduces the manufacturing cost of the equipment but also avoids the extra energy consumption caused by the simultaneous operation of multiple heating components. At the same time, subsequent maintenance and repair of the heating system are more convenient, reducing the equipment operation and maintenance costs. Attached Figure Description
