Description

Technical Field

[0001] The utility model belongs to the technical field of quenching technology, and particularly relates to a novel multifunctional quenching material rack. Background Art

[0002] High-performance fastener products are usually used in key fields such as aviation, aerospace, and navigation. During the production process, they usually need to go through high-temperature solid solution water quenching + aging heat treatment process to improve the performance of the product so that it can meet service requirements.

[0003] Non-ferrous metal raw material manufacturers are required to test the solution-aged mechanical properties of rod and wire raw material samples before they leave the factory. This testing typically uses a continuous step-type solution furnace for heat treatment. This equipment offers advantages such as high stability during the solutionization process and rapid product transfer into water, ensuring consistent hardening and microstructure performance. Fastener manufacturers typically use this type of furnace for production, but it carries the risk of high procurement and maintenance costs and long production cycles. Due to cost constraints, rod and wire raw material manufacturers do not equip themselves with dedicated automatic transfer water quenching furnaces, typically using multiple box-type resistance furnaces for heat treatment. In actual operation, after the furnace door is opened, the material rack must be removed from the furnace using a forklift or long-arm clamp. Due to the high solution temperature, the material cannot be quickly transferred when forking or clamping, resulting in a drop in sample temperature and failure to achieve the desired hardening effect. There is also the risk of material falling into or out of the furnace during transfer.

[0004] Furthermore, to meet the testing needs of various material types, temperature ranges, specifications, and batches, while also balancing production capacity, sample testing sites typically employ 30-50 box-type resistance furnaces of varying sizes. These furnaces vary in size, temperature range, and effective heating zone. Therefore, it is necessary to design an adjustable heat treatment rack that can rapidly solution-quench fastener raw materials and accommodate a variety of sizes and specifications.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a new multifunctional quenching rack.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A novel multifunctional quenching rack comprises a first rack having a material placement area with a plurality of rectangular grid-like structures and a telescopic clamping rod, one end of the telescopic clamping rod being fixedly connected to one side of the first rack, and a second rack being detachable and convenient for expanding the material placement area being provided on a side of the first rack away from the telescopic clamping rod, the other end of the telescopic clamping rod being a telescopic structure; the rectangular grids in the material placement area have an optional thickness of 5-10 mm, a grid spacing of 10 mm, and an optional grid width of 5-10 mm, and can be used for heat treatment and quenching of all metal materials such as bars or tubes of any diameter within the specification range of Φ1.0 mm to Φ70 mm.

[0009] Specifically, sleeves are provided on both sides of the first material rack, and sleeve rods adapted to the sleeves are provided on both sides of the second material rack to achieve detachable connection between the first material rack and the second material rack, and the sleeves and the sleeve rods are clearance-matched.

[0010] Specifically, each sleeve is provided with a first fixing hole, each sleeve rod is provided with a second fixing hole adapted to the first fixing hole, and the first fixing hole and the second fixing hole are connected detachably to the first material rack and the second material rack by bolts.

[0011] Specifically, support ribs are fixedly provided at the bottom of the first material rack and the second material rack.

[0012] Specifically, each of the rectangular grids is parallel to the telescopic clamping rod.

[0013] Specifically, the telescopic clamping rod includes an inner tube fixedly connected to the first material rack, a clamping handle for facilitating clamping, and an outer tube for adjusting the distance between the inner tube and the clamping handle.

[0014] Specifically, the first material rack is fixedly connected to the inner tube by high-temperature resistant bolts, which is convenient for replacement in case of wear and tear.

[0015] Specifically, the inner tube and the clamping handle are both loosely matched with the outer tube.

[0016] Specifically, the inner tube and the clamping handle are each provided with a first through hole at one end close to each other, and a plurality of second through holes that are compatible with the first through holes are evenly provided on both sides of the outer tube. The first through holes are connected with different second through holes by bolts to adjust the length and extension of the telescopic clamping rod. Through the displacement of the hole positions, various adjustments of the length structure are achieved to meet the use requirements of the effective area of ​​any furnace size, and the use of bolts facilitates the replacement of parts due to wear and tear.

[0017] Specifically, the inner tube, the clamping handle, and the outer tube are all made of high-temperature resistant materials, and the bolts are high-temperature resistant bolts.

[0018] Specifically, the high temperature resistant material is 5Ni20Si2 heat resistant steel.

[0019] The first and second racks of this multifunctional quenching rack are expandable working areas and consist of two parts, a telescopic clamping rod. The first rack and the telescopic clamping rod are connected by bolts. During the furnace loading process, the expandable working area is located in the effective furnace temperature zone and as far away from the furnace door as possible to avoid temperature drops of the sample after the furnace door is opened. The telescopic clamping rod is adjusted so that the telescopic end pipe mouth is as close to the furnace door as possible for easy clamping. During operation, the sample is placed in the expandable working area and the expandable working area is placed in the effective furnace temperature zone. The telescopic end pipe mouth is as close to the furnace door as possible. The quenching rack heats up with the furnace. When it is time to take the sample out of the furnace, the furnace door is opened about 50-70 mm, which meets the requirements of the quenching rack's out-of-furnace operation, effectively reducing furnace temperature loss. A long-arm clamp is used to quickly support the telescopic clamping rod and extract the quenching rack, while completing the water quenching operation at the same time, saving time.

[0020] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0021] This utility model primarily addresses the issue of long-lasting high-temperature quenching and furnace exit times for nonferrous metal wire rods. Adjusting the telescopic clamping rod addresses the issue of varying furnace effective area sizes. Furthermore, it adds expandable racks, increases sample loading capacity, improves production capacity, and enhances efficiency, saving costs. This utility model also meets the needs of water quenching and solutionizing heat treatment samples for fastener materials in the nonferrous industry, effectively improving heat treatment stability, shortening heat treatment solutionization operation time, and addressing the impact of furnace temperature drop on samples. Because it is relatively simple to manufacture and operate, even individuals with no prior experience can operate it. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example

[0032] See also Figure 1-4 As shown, this embodiment provides a new multifunctional quenching rack, including a first rack 1 with a material placement area having multiple rectangular grid-like structures and a telescopic clamping rod 2, one end of the telescopic clamping rod 2 is fixedly connected to one side of the first rack 1, and the first rack 1 is further provided with a second rack 3 on the side away from the telescopic clamping rod 2 that can be disassembled and facilitates the expansion of the material placement area.

[0033] Specifically, sleeves 11 are provided on both sides of the first material rack 1, and sleeve rods 31 adapted to the sleeves 11 are provided on both sides of the second material rack 3 to achieve a detachable connection between the first material rack 1 and the second material rack 3, and the sleeves 11 and the sleeve rods 31 are clearance-fitted.

[0034] Specifically, each sleeve 11 is provided with a first fixing hole 12, and each sleeve rod 31 is provided with a second fixing hole 32 adapted to the first fixing hole 12. The first fixing hole 12 and the second fixing hole 32 are detachably connected to the first material rack 1 and the second material rack 3 by bolts.

[0035] Specifically, support ribs are fixedly provided at the bottom of the first material rack 1 and the second material rack 3 .

[0036] Specifically, each of the rectangular grids is parallel to the telescopic clamping rod 2 .

[0037] Specifically, the telescopic clamping rod 2 includes an inner tube 21 fixedly connected to the first material rack 1 , a clamping handle 22 for easy clamping, and an outer tube 23 for adjusting the distance between the inner tube 21 and the clamping handle 22 .

[0038] Specifically, the first material rack 1 is fixedly connected to the inner tube 21 by high-temperature resistant bolts, which is convenient for replacement in case of wear and tear.

[0039] Specifically, the inner tube 21 and the clamping handle 22 are both loosely fitted with the outer tube 23 .

[0040] Specifically, the inner tube 21 and the clamping handle 22 are each provided with a first through hole at one end close to each other, and a plurality of second through holes compatible with the first through holes are evenly provided on both sides of the outer tube 23. The first through holes are connected with different second through holes by bolts to adjust the length and extension of the telescopic clamping rod 2. Through the displacement of the hole positions, various adjustments of the length structure are achieved to meet the use requirements of the effective area of ​​any furnace size. The use of bolts facilitates the replacement of parts after wear and tear.

[0041] Specifically, the inner tube 21 , the clamping handle 22 , and the outer tube 23 are all made of high-temperature resistant materials, and the bolts are high-temperature resistant bolts.

[0042] Specifically, the high temperature resistant material is 5Ni20Si2 heat resistant steel.

[0043] For example, a certain brand of fastener material requires a quenching temperature of 955°C ± 15°C at room temperature. Because the material is typically small, to minimize temperature loss during sample transfer, the water quenching process must be completed within 5 seconds, starting when the furnace door opens and the temperature drops. Any delay exceeding 5 seconds will directly result in abnormalities in the quenched specimen, leading to skewed or unqualified performance data in the test report. This will prevent the material from providing true mechanical performance indicators, resulting in product failure. The first and second racks 1, 3 of this multifunctional quenching rack are designed to accommodate specimens within an expandable working area. The racks are connected by bolts to the telescopic clamping rod 2, which is located in the work area. During loading, the expandable working area is located within the effective furnace temperature range and as far away from the furnace door as possible to minimize sample temperature drop after the door opens. The telescopic clamping rod 2 is adjusted to make the inner tube as close to the furnace door as possible for easy clamping operation; during operation, the sample is placed in the expandable working area, and the expandable working area is placed in the effective range of the furnace temperature. The length of the clamping tube is adjusted to make the clamping end as close to the furnace door as possible. The quenching rack heats up with the furnace. When the time for taking out of the furnace is reached, the furnace door is opened about 50-70 mm, which can meet the requirements of the quenching rack for taking out of the furnace, and effectively reduce the loss of furnace temperature. The long-arm clamp is used to quickly support the telescopic clamping rod 2 and extract the quenching rack, and the water quenching operation is completed at the same time, saving time.

[0044] The above description is merely a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
