Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment tooling, and particularly relates to a heat treatment tray for ring-shaped workpieces. Background Art

[0002] In the metal processing industry, heat treatment is a key process for improving material properties, enhancing mechanical characteristics, and extending service life, and its importance is self-evident. A heat treatment tray is an essential tooling in the heat treatment production process. In the continuous and large-batch heat treatment production process, it is required that the heat treatment tray has the characteristics of small high-temperature deformation, durability, good heating and cooling cycle effects, simple loading and unloading, and high versatility.

[0003] However, the existing heat treatment trays generally adopt a single planar shape design, which is particularly inadequate when dealing with ring-shaped workpieces. Due to the limitation of the planar structure, ring-shaped workpieces are extremely prone to rolling during the loading and unloading process, which not only increases the operation difficulty but also brings serious safety hazards. Operators need to spend a lot of time stabilizing the workpieces, resulting in low overall loading and unloading efficiency.

[0004] In addition, there are many unreasonable aspects in the design of traditional heat treatment trays. First of all, its overall structure is often relatively heavy, which not only increases the material cost and makes the tray expensive, but also limits the flexibility of use due to its excessive weight. Secondly, the heavy structure is often accompanied by low durability, so the service life of the tray is limited, and frequent replacement further increases the operating cost of the enterprise. More importantly, such trays perform poorly in heat transfer and heat dissipation performance, resulting in difficult temperature control of workpieces during heat treatment. During the heating and cooling cycle of workpieces, due to uneven temperature distribution, the heat treatment effects are often inconsistent, seriously affecting the quality stability and consistency of workpieces.

[0005] Therefore, in order to solve the problems that the existing heat treatment trays have significant deficiencies in terms of shape, operation convenience, cost-effectiveness, service life, and heat treatment effects, and cannot meet the urgent needs of the modern metal processing industry for efficient, safe, and high-quality production, a heat treatment tray for ring-shaped workpieces is now needed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a heat treatment tray for ring-shaped workpieces, which has a simple structure and is easy to operate, can be applicable to the heat treatment of ring-shaped workpieces, is resistant to high temperature and has a small deformation amount, effectively improves the heating and cooling cycle effects, and improves the loading and unloading effects.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The utility model effectively improves the versatility of the tray tooling for the heat treatment of ring-shaped workpieces, extends the service life, improves the quality of workpiece heat treatment, and enhances the overall heat treatment efficiency. Specifically, a heat treatment tray for ring-shaped workpieces is provided, including a tray body, on the upper surface of the tray body, a plurality of V-shaped grooves for placing workpieces are arranged side by side; on both side surfaces of the V-shaped grooves, a plurality of weight-reducing grooves are respectively arranged; the weight-reducing grooves are of a polygonal structure; on both sides of the tray body, lifting lugs for lifting are further arranged.

[0010] This solution uses V-shaped grooves to place ring-shaped workpieces, which is convenient for loading and unloading, ensures the stability of the workpieces, reduces potential safety hazards during the loading and unloading process, and improves efficiency and safety. And weight-reducing grooves are arranged on the surfaces of the V-shaped grooves, which have high space utilization rate, strong structural stability, and save materials. Through the hollow weight-reducing grooves, good heat and cold circulation can be provided, the stress during high temperature and cooling processes can be dispersed and transmitted, effectively preventing deformation at high temperatures, improving the overall stability and durability, and effectively improving the quality of workpiece heat treatment. The lifting lugs facilitate loading, unloading and lifting, and ensure the stability and safety during the lifting process. This solution effectively improves the heat resistance of the tray, enhances the versatility, extends the service life of the tooling, improves the overall heat treatment efficiency, makes the heating and cooling cycle more sufficient, improves the quality of product heat treatment, ensures product consistency, and reduces production costs.

[0011] Furthermore, there are two V-shaped grooves, and the connection part between adjacent V-shaped grooves is of a rounded corner structure. Rounded corner treatment is adopted at the connection part to avoid scratching the surface of the workpiece and ensure the quality of the workpiece during the heat treatment process.

[0012] Furthermore, the weight-reducing grooves are of a hexagonal structure, and the depth of the weight-reducing grooves is 100 - 200 mm. Setting the weight-reducing grooves as hexagons, on the one hand, it has higher space utilization rate and can provide better heat and cold circulation; on the other hand, with a hexagonal structure, its structural stability is strong, effectively reducing the deformation amount; at the same time, setting the depth of the weight-reducing grooves to 100 - 200 mm can not only save the use of materials, but also ensure the stability of the tray, and can better disperse and transmit the stress during high temperature and cooling processes, achieving a better cooling cycle effect and preventing deformation at high temperatures.

[0013] Furthermore, the width of the tray body is 800 - 2400 mm, the length is 1000 - 3500 mm; the thickness is 100 - 200 mm. To ensure the load-bearing capacity of the tray body, improve the heat resistance of the tray body at the same time, and effectively reduce the deformation amount.

[0014] Furthermore, the depth of the V-shaped grooves is 50 - 150 mm. Ensure that the ring-shaped workpieces can be placed stably, avoid the rolling of the workpieces, and improve the loading safety.

[0015] Furthermore, the opening angle of the V-shaped groove is 120°-160°. It meets the design depth requirements of the weight reduction groove, and at the same time can ensure the stable placement of the annular workpiece, facilitating loading and unloading, and improving operation efficiency and safety.

[0016] Furthermore, there are four lifting lugs, which are respectively arranged at both ends of the tray body. During the loading and unloading process, the tray is lifted by the four lifting lugs to ensure the balance and stability of the lifting, facilitating operation and improving safety at the same time.

[0017] Furthermore, the lifting lug is a positioning block and is integrally formed with the tray body. Ensure the stability of the lifting lug.

[0018] Furthermore, the tray body is integrally cast from heat-resistant steel. Improve the heat resistance of the tray body, reduce the deformation amount, and at the same time is easy to produce and process, effectively reducing the production and manufacturing cost, and can be recycled and reused.

[0019] Furthermore, the width of the lifting lug is 200-400mm. Facilitate lifting and installation, and ensure the stability and safety during the lifting process to avoid slipping. BRIEF DESCRIPTION OF THE DRAWINGS
