Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and more specifically, to a heat treatment apparatus for alloy bars. Background Technology

[0002] Heat treatment of alloy bars is a key technology that uses a cycle of heating, holding, and cooling to adjust the internal microstructure of the bars to optimize their performance. The core of this technology is to determine the temperature parameters based on the alloy composition (such as aluminum alloys, titanium alloys, high-strength steel, etc.), and to control the holding time (1-4 hours, adjusted according to the bar diameter) to allow the alloying elements to diffuse fully. Then, the microstructure is transformed by water quenching, air cooling, or oil cooling (such as the precipitation of strengthening phases in aluminum alloys and the formation of martensite in steel bars), which ultimately improves the strength of the bars.

[0003] A search revealed that Chinese Patent Publication No. CN202223445697.2 discloses "a heat treatment device for metal bars, comprising: a main unit, which includes a base and a heating furnace fixedly installed on one end of the upper side wall of the base; the heating furnace has a feed inlet on one side near the center of the base; a heat source box is fixedly connected to the upper end of the heating furnace; an air inlet pipe is fixedly connected to the side wall of the heat source box; an air pump connected to the air inlet pipe is fixedly installed on the upper side wall of the heat source box; and an electric heating wire is fixedly installed inside the heat source box."

[0004] The aforementioned patent involves placing the metal rods to be heat-treated in a feeding hood and then placing them in a heating furnace for heat treatment. Although the aforementioned patent uses a motor to drive multiple metal rods to rotate, thereby achieving uniform heat treatment, the use of motors and other devices increases the cost of the device. Furthermore, the metal rods are in contact with each other, which reduces the heating effect. Therefore, we have designed an alloy rod heat treatment device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a heat treatment device for alloy bars, including a mounting plate 1 and a side mounting plate 2. The mounting plate 1 and the side mounting plate 2 are arranged in parallel, with the side mounting plate 2 positioned higher than the mounting plate 1. By positioning the side mounting plate 2 higher than the mounting plate 1, the alloy bars 3 can be tilted, thus making the alloy bars 3 more stable. Multiple limiting ring plates 4 are fixed at intervals on the side wall of the mounting plate 1. Multiple insertion holes 5 are spaced apart on the side mounting plate 2. Alloy bars 3 are placed in each of the multiple insertion holes 5, with one end of the alloy bars 3 passing through the insertion hole 5 and inserted into the limiting ring plate 4. By placing multiple alloy bars 3 with one end passing through the multiple insertion holes 5 into the limiting ring plate 4, the multiple alloy bars 3 can be horizontally limited. The device can then be placed in a heating furnace for heating.

[0025] Telescopic mechanisms are connected between the two side walls of mounting plate 1 and side mounting plate 2. A base plate 14 is provided directly below mounting plate 1 and side mounting plate 2. A support plate 15 is fixed above the two base plates 14 and between mounting plate 1 and side mounting plate 2. A handle 16 is fixed to the side wall of the support plate 15. The distance between mounting plate 1 and side mounting plate 2 can be adjusted by telescopic mechanisms, so as to facilitate the horizontal limiting of alloy rods 3 of different lengths.

[0026] The telescopic mechanism includes a lower plate 7 and an upper plate 8. The lower plate 7 is fixed to both sides of the side wall of the mounting plate 1, and the upper plate 8 is fixed to both sides of the side wall of the side mounting plate 2. The upper plate 8 has a sliding hole 6. The lower plate 7 has a telescopic rod 9 fixed to its side wall. The telescopic rod 9 includes a sleeve 91 and a sliding rod 92. The sleeve 91 is fixed to the side wall of the lower plate 7, and one end of the sliding rod 92 is fixed to the side wall of the side plate 12. The other end of the sliding rod 92 is slidably disposed in the sleeve 91, and a rod limiting plate 93 is fixed to the other end of the sliding rod 92. The side plate 12 can be moved conveniently through the telescopic rod 9.

[0027] One end of the telescopic rod 9 passes through the sliding hole 6 and is fixed to a side plate 12. A pull ring 13 is fixed to one side of the side plate 12. Limiting mechanisms are provided between the two sides of the side wall of the side plate 12 and the upper plate 8. The limiting mechanisms include multiple limiting grooves 10 and limiting plates 11. The multiple limiting grooves 10 are spaced apart on the side wall of the upper plate 8. The limiting plates 11 are fixed to the side wall of the side plate 12 and are inserted into the limiting grooves 10. By inserting the limiting plates 11 into the limiting grooves 10, the side plate 12 can be limited, thereby limiting the distance between the lower plate 7 and the upper plate 8. When it is necessary to adjust the distance between the mounting plate 1 and the side mounting plate 2, simply pull the pull ring 13 to pull the limiting plate 11 out of the limiting groove 10, and then adjust the distance between the mounting plate 1 and the side mounting plate 2. When the distance is adjusted to a suitable position, the limiting plate 11 is then inserted into the limiting groove 10 at the appropriate position.

[0028] The working principle and usage process of this utility model are as follows: By passing one end of multiple alloy rods 3 through multiple insertion holes 5 and placing them in the limiting ring plate 4, the multiple alloy rods 3 can be horizontally limited. Then, the device can be placed in a heating furnace for heating. By separating and limiting the multiple alloy rods 3, the multiple alloy rods 3 can be better heat treated. The distance between the mounting plate 1 and the side mounting plate 2 can be adjusted by the telescopic mechanism, so as to conveniently separate and horizontally limit alloy rods 3 of different lengths.
