Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, and in particular to a precise and stable heating furnace isolation pad. Background Technology

[0002] In the production and processing of mechanical products, high-temperature treatment in a heating furnace is typically used to ensure product quality. Cylindrical products, such as connecting shafts and support columns, are usually placed in a single layer within the furnace, separated by spacers. This results in relatively poor space utilization within the furnace. Furthermore, existing spacers, being cuboid in structure, are susceptible to cracking under stress during use, leading to a shorter lifespan. They also cannot achieve a fully uniform fit with the mechanical product, causing uneven heating in the initial stages. To address this technical issue, the company developed an insulating heating spacer that effectively ensures safety and extends service life. However, its load-bearing capacity cannot be guaranteed during installation, and the precision of its alignment along the central axis cannot be guaranteed, resulting in relatively poor ease of use. Utility Model Content

[0003] The purpose of this invention is to provide a precise and stable heating furnace isolation pad. By setting a secure and heat-resistant mating groove on one side of the pad, it effectively prevents cracking during use and rapidly dissipates hard forces during heating. The two sets of mutually cooperating stable mating grooves not only allow for better deformation of the opening but also precisely limit the direction of the opening as needed. This ensures that the stacked pads do not interfere with each other during use, resulting in more uniform heating, improved safety of the mechanical product during heating, and a longer service life. Furthermore, by setting installation mating structures on the upper and lower sides of the overall structure, it can quickly combine with the slide rail structure through a sliding fit. The evenly distributed precise installation limiting mating grooves on the outer side allow for rapid and accurate setting of the mating position, enhancing convenience during use and making installation and assembly operations easier.

The main isolation assembly base has integrally formed and symmetrically distributed mounting support and stabilizing columns on its upper and lower sides. On the outer side of the mounting support and stabilizing columns in the upper and lower directions, there is an integrally formed sliding mounting and stabilizing column. The sliding mounting and stabilizing column has an elliptical cross-section. The width of the sliding mounting and stabilizing column in the left and right directions is greater than the length of the mounting support and stabilizing column in the left and right directions. On the outer side of the sliding mounting and stabilizing column in the upper and lower directions, there are evenly distributed installation precision limiting grooves. The installation precision limiting grooves intersect with the mounting support and stabilizing column.

[0005] Furthermore, the width of the outer side of the precise positioning groove is greater than the width of the inner side.

[0006] Furthermore, the length of the mounting support and stabilizing column in the front-to-back direction is the same as the length of the main body isolation assembly seat in the front-to-back direction.

[0007] Furthermore, the width and depth in the vertical direction of the first and second stable mating grooves are the same.

[0008] Furthermore, the width of the safety heat-resistant mating groove in the vertical direction is less than one-quarter of the diameter of the central assembly hole.

[0009] Furthermore, the front and rear edges of the central assembly hole are provided with chamfered structures for easy installation and assembly.

[0010] Furthermore, the main isolation assembly is made of Cr25Ni20 material.

[0011] The beneficial effects of this utility model are: This invention features a heat-resistant and secure fitting groove on one side of the pad, effectively preventing cracking during use and rapidly dispersing hard forces during heating. The two combined, mutually cooperating fitting grooves not only enhance the deformation capacity of the opening but also allow for precise directional control of the opening. This ensures that the stacked pads do not interfere with each other during use, resulting in more uniform heating and improved safety and lifespan for the mechanical product. Furthermore, the installation fitting structures on the upper and lower sides of the overall structure allow for rapid assembly with the slide rail structure via a sliding fit.

[0013] like Figures 1 to 7As shown, a precision and stable heating furnace isolation pad includes a cylindrical main isolation assembly base 1 with its central axis pointing forward and backward, which is the main structure of the pad. The main isolation assembly base 1 has a cylindrical central assembly hole 2 extending forward and backward along its central axis. During use, it can be fitted and assembled with the mechanical product to be heated, isolating it from other mechanical products and preventing mutual interference during heating. A safety heat-resistant fitting groove 3 extending forward and backward along the right side of the central assembly hole 2 provides reliable deformation space on the right side and effectively relieves stress during heating, preventing cracking under stress and improving service life. The inner and outer edges of the safety heat-resistant fitting groove 3 are respectively provided with safety avoidance rounded corners 5, avoiding sharp corners and improving safety during use, preventing scratches between the mating mechanical product and the groove. The upper end of the safety and heat-resistant mating groove 3 is provided with a first stable mating groove 4 evenly distributed front and back, and the lower end of the safety and heat-resistant mating groove 3 is provided with a second stable mating groove 6 evenly distributed front and back. This allows for a larger space at the opening position, while ensuring better structural strength at the opening position, achieving a second stress relief effect, and making the crack prevention effect more reliable. The upper and lower sides of the main isolation assembly seat 1 are respectively provided with integrally formed and symmetrically distributed installation support and stabilizing mating columns 7, which can provide support, reinforcement, and isolation during installation. The outer side of the installation support and stabilizing mating column 7 in the upper and lower directions is provided with an integrally formed sliding installation and stabilizing mating column 8. This position allows for a safe and stable sliding engagement with a slide rail-like structure, and can be moved stably as needed. The cross-section of the sliding installation and stabilizing mating column 8 is an elliptical structure, resulting in higher structural load-bearing strength at the mating position, a larger mating area, and better stability during movement. The width of the sliding installation and stabilizing mating column 8 in the left and right directions is greater than the length of the installation support and stabilizing mating column 7 in the left and right directions, making production and processing more convenient and ensuring greater structural safety during use. The sliding mounting and stabilizing column 8 has evenly distributed precision positioning grooves 9 on its outer sides in the vertical direction. These grooves allow for quick and precise positioning by inserting a precision positioning plate when the column is moved to the appropriate position, ensuring higher positional accuracy during engagement. The precision positioning grooves 9 intersect with the mounting and stabilizing column 7, providing more space for the engagement position and more reliable stability.By incorporating a heat-resistant and secure fitting groove on one side of the pad, it effectively prevents cracking during use and rapidly decomposes hard forces during heating. The two sets of mutually cooperating stable fitting grooves not only enhance the deformation capacity of the opening but also allow for precise directional control of the opening. This ensures that the stacked pads do not interfere with each other during use, resulting in more uniform heating and improved safety and lifespan for the mechanical product. Furthermore, the installation fitting structure on both the upper and lower sides of the overall structure allows for rapid assembly with the slide rail structure via a sliding fit. The evenly distributed, precise fitting grooves on the outer side allow for quick and accurate setting of the fitting position, enhancing ease of use and simplifying installation and assembly.

[0014] Preferably, the width of the outer side of the installation precision limiting groove 9 is greater than the width of the inner side, which makes the operation of fitting the limiting component more convenient and provides more space on the outer side.

[0015] Preferably, the width and vertical depth of the first stabilizing groove 4 and the second stabilizing groove 6 are the same, which makes the structural stability of both sides better. They can also be used without regard to the vertical direction, and can be flipped over, which makes them more convenient to use and further improves their durability.

[0016] Preferably, the length of the mounting support and stabilizing column 7 in the front-to-back direction is the same as the length of the main body isolation assembly seat 1 in the front-to-back direction, so that the overall strength of the mounting bearing position can be maximized and the durability during use is stronger.

[0017] Preferably, the width of the safety heat-resistant mating groove 3 in the vertical direction is less than one-quarter of the diameter of the central assembly combination hole 2, which makes the main structure stronger, the isolation and protection mating area larger during use, and the protection effect better.

[0018] Preferably, the front and rear edges of the central assembly hole 2 are provided with chamfered structures for easy installation and assembly, which makes assembly and assembly more convenient, has a guiding function, and can improve the efficiency of assembly.

[0019] Preferably, the main isolation mounting base 1 is made of Cr25Ni20 material, which has a relatively low production cost and better heat resistance during use.

[0020] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
