Description

Technical Field

[0001] The present invention belongs to the technical field of calibration equipment, and relates to a calibration bracket device and method, in particular to a high temperature resistant metal calibration device and method. Background Art

[0002] In the field of metal processing technology, vacuum tempering furnace is a common equipment, which is mainly used for heat treatment of metal. During use, the temperature in the furnace needs to be accurately controlled to ensure the effect of heat treatment. This requires the use of temperature calibration device to evaluate the temperature uniformity in the furnace by measuring the temperature at multiple points in the furnace. However, due to the different internal dimensions of vacuum tempering furnaces, calibration frames of different sizes need to be used, which increases the cost of equipment use. In the field of calibration equipment manufacturing, the existing solution is usually to design dedicated calibration frames for different internal dimensions. These frames are usually made of high-temperature resistant materials, such as graphite, to ensure stability in high temperature environments. However, the disadvantage of this method is that the scope of application of each frame is limited. Once the internal dimensions of the equipment change, a new frame needs to be replaced, which undoubtedly increases the cost of equipment use. In the field of high-temperature material applications, graphite is a commonly used high-temperature resistant material with good thermal and chemical stability. However, how to use graphite to make a retractable calibration frame to adapt to equipment of different sizes remains a challenge. 2) Solutions of the prior art: The existing solutions mainly involve designing special calibration frames whose dimensions match the internal dimensions of the equipment, so as to accurately measure the temperature inside the furnace during the temperature calibration process. However, the disadvantage of this method is that the scope of application of each frame is limited. Once the internal dimensions of the equipment change, a new frame needs to be replaced, which undoubtedly increases the cost of using the equipment. 3) Problems with the prior art: The problems existing in the prior art in this field are mainly the following: First, due to the different internal dimensions of the equipment, calibration frames of different sizes need to be used, which increases the cost of using the equipment. Secondly, most of the existing calibration frames are of fixed size and cannot adapt to changes in the internal dimensions of the equipment, which limits their scope of use. Finally, most of the existing calibration frames are made of high-temperature resistant materials, such as graphite, but these materials are difficult to process, which increases the manufacturing cost of the frame.

[0003] Therefore, the present invention proposes a high temperature resistant metal calibration bracket device with adjustable size, which can overcome the above problems.

[0004] After searching, no public documents of the prior art that are identical or similar to the present invention were found. Summary of the invention

DETAILED DESCRIPTION

[0034] The following further describes the embodiments of the present invention:

[0035] A high temperature resistant metal calibration device, such as Figure 1 and Figure 2As shown, it is a hollow polyhedron frame, which includes: multiple telescopic mechanisms for adjusting the length along the X-axis direction, multiple telescopic mechanisms for adjusting the length along the Y-axis direction, and multiple telescopic mechanisms for adjusting the length along the Z-axis direction; the hollow polyhedron frame can be independently adjusted along three axes.

[0036] In this embodiment, the telescopic mechanism comprises: a fixed sleeve and a telescopic rod, the telescopic rod is slidably connected inside the fixed sleeve, and a guiding movement mechanism is connected between the telescopic rod and the fixed sleeve;

[0037] In this embodiment, a positioning pin is provided on the fixing sleeve.

[0038] In this embodiment, a scale groove is provided on the fixing sleeve.

[0039] In this embodiment, the telescopic mechanism is driven electrically and hydraulically.

[0040] In this embodiment, the telescopic mechanism is made of a high temperature resistant metal material.

[0041] In this embodiment, the guide motion mechanism adopts a high temperature resistant graphite bushing.

[0042] In this embodiment, a retractable metal calibration bracket is designed, which is made of high temperature resistant metal materials, such as stainless steel, to ensure stability and durability in high temperature environments. The retractable function of the bracket can be achieved in a variety of ways, such as electric drive, hydraulic drive, etc., to meet the needs of equipment with different internal sizes.

[0043] In this embodiment, a positioning pin is provided on the bracket. By adjusting the position of the positioning pin, the size of the bracket can be accurately adjusted to ensure the stability of the size of the bracket, thereby improving the accuracy of calibration. At the same time, the design of the positioning pin can also conveniently fix the bracket inside the device, improving the convenience of use.

[0044] In this embodiment, a scale groove is provided on the bracket, through which the current size of the bracket can be intuitively seen, so that the size of the bracket can be adjusted more accurately. At the same time, the bracket size required for calibration of different devices can also be recorded to facilitate next use and improve work efficiency.

[0045] In this embodiment, the guide rail movement mechanism of the bracket adopts a high-temperature resistant graphite bushing, which has good high-temperature resistance and lubricity, and can ensure the smooth operation of the bracket, while also reducing the wear of the bracket and extending its service life.

[0046] In this embodiment, the three axes of the bracket are adjusted independently, which can more flexibly adapt to the complex structure inside the device and improve the application range of the bracket. At the same time, the three-axis independent adjustment can also avoid the bracket size deviation caused by improper adjustment and improve the accuracy of calibration.

[0047] A method for manufacturing a high temperature resistant metal calibration device comprises the following steps:

[0048] Step 1. Select a high temperature resistant metal material, such as stainless steel, to make a retractable metal calibration bracket; the length of the bracket is set to 500 mm, the width is set to 300 mm, and the height is set to 200 mm. These dimensions can be adjusted according to actual needs.

[0049] Step 2: Set locating pins on the bracket. The number of locating pins is 6, and the distance between every two locating pins is 50 mm. By adjusting the position of the locating pins, the size of the bracket can be accurately adjusted to ensure the size stability of the bracket.

[0050] Step 3: Set a scale groove on the bracket, the minimum scale of the scale groove is 1mm, and the maximum scale is 500mm. Through the scale groove, you can intuitively see the current size of the bracket, so as to adjust the size of the bracket more accurately.

[0051] In this embodiment, the guide rail movement mechanism on the metal calibration bracket adopts a high temperature resistant graphite sleeve, the inner diameter of the graphite sleeve is 10 mm, the outer diameter is 20 mm, and the length is 100 mm. The graphite sleeve has good high temperature resistance and lubricity, which can ensure the smooth operation of the bracket and reduce the wear of the bracket.

[0052] In this embodiment, the metal calibration bracket can be independently adjusted in three axes, which can more flexibly adapt to the complex structure inside the equipment and improve the scope of application of the bracket. The three-axis independent adjustment can also avoid the bracket size deviation caused by improper adjustment and improve the accuracy of calibration. The above are the specific operating steps of this embodiment. In this way, a temperature uniformity bracket with adjustable size can be realized, which can withstand high temperatures and adapt to vacuum tempering furnaces of different sizes, reduce operating costs, and facilitate operation.

[0053] The innovation of the present invention lies in:

[0054] Compared with the prior art, this technical solution mainly solves the following problems:

[0055] 1) Due to the different internal dimensions of the equipment, calibration frames of different sizes need to be used, which increases the cost of using the equipment;

[0056] 2) Most existing calibration frames are of fixed size and cannot adapt to changes in the internal size of the equipment, which limits their scope of use;

[0057] 3) Most existing calibration frames are made of high temperature resistant materials, such as graphite, but these materials are difficult to process, which increases the technical problem of the manufacturing cost of the frame.

[0058] Due to the advanced nature of the technical solution, it can be widely used in the fields of metal processing technology, calibration equipment manufacturing and high-temperature material application. In the field of metal processing technology, the temperature uniformity bracket with adjustable size of the present invention can effectively reduce the use cost of the equipment and improve production efficiency.
