After the metal powder in the combustion chamber is processed, the processed metal powder is discharged into the discharge chamber for cooling by opening the second discharge valve. In actual operation, the feed inlet is opened by a control valve, and standard-sized metal powder is added to the combustion chamber through the storage chamber. Then, the first discharge valve is closed, and standard-sized metal powder is added to the storage chamber through the feed inlet and stored in the storage liner. After the metal powder in the combustion chamber is processed, the processed metal powder is discharged into the discharge chamber for cooling by opening the second discharge valve. Then, the first discharge valve is opened to add the metal powder in the storage liner into the combustion chamber for further processing. After processing, the powder is discharged sequentially through the discharge outlet. This invention has the following technical problems:

[0005] In actual use, the storage chamber and combustion chamber are usually fixedly connected by multiple bolts for easy maintenance. The combustion chamber and the discharge chamber are also fixedly connected by bolts. However, the multiple bolts make the installation and disassembly process more complicated.

Detailed Implementation

[0027] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0028] Please see Figures 1-5 This utility model provides an annealing device for oil perforating projectile casing blanks, comprising three functional chambers: a storage chamber 10, a combustion chamber 20, and a discharge chamber 30. The oil perforating projectile casing blank is fed into the storage chamber 10, then transported to the combustion chamber 20 for heat treatment, and subsequently transported to the discharge chamber 30 for cooling. A first connecting ring 100 and a second connecting ring 200 connect the storage chamber 10 and the combustion chamber 20. The first connecting ring 100 and the second connecting ring 200 also connect the combustion chamber 20 and the discharge chamber 30, and connect adjacent functional chambers to maintain stability.

[0029] The lower end of the first connecting ring 100 is equipped with four positioning blocks 110 for positioning the first connecting ring 100 in conjunction with the second connecting ring 200. The middle of the first connecting ring 100 is equipped with four limiting sliders 130. The middle of the first connecting ring 100 has four mounting grooves 120 for limiting the limiting sliders 130. The limiting sliders 130 are placed within the cavities of the mounting grooves 120. Mounting grooves 121 are formed on the middle of both sides of the cavity of the mounting grooves 120, and threaded holes 122 are formed in the middle of the cavity of the mounting grooves 121.

[0030] Positioning blocks 131 are fixedly installed on both sides of the limiting slider 130, and the positioning blocks 131 are installed in the cavity of the mounting groove 121. A bolt 132 for locking the limiting slider 130 with the threaded hole 122 is installed in the middle of the positioning block 131. A ball bearing 133 is installed at the lower end of the limiting slider 130 to facilitate the rotation of the first connecting ring 100. Under the action of the ball bearing 133, the first connecting ring 100 can drive the storage chamber 10 or the combustion chamber 20 to rotate.

[0031] The second connecting ring 200 includes a fixing ring 210. The fixing ring 210 has four positioning grooves 211 in its middle for positioning the positioning block 110. When installing the first connecting ring 100 and the second connecting ring 200, the positioning block 110 is inserted into the groove of the positioning groove 211. The upper end of the fixing ring 210 has four sets of sliding grooves 212 for the ball bearing 133 to slide, and each set of sliding grooves 212 includes two arc-shaped grooves.

[0032] Four support blocks 220 are installed in the middle of the fixed ring 210 to support the limiting slider 130. The length of the first slide groove 212 and the support blocks 220 is equal to the length of the second positioning groove 211, and the length between the first positioning block 110 and the limiting slider 130 is equal to the length of the first slide groove 212, so that when the first positioning block 110 moves to the side of the second positioning groove 211 close to the first slide groove 212, the limiting slider 130 just moves to the upper end of the support block 220.

[0033] A power assembly 230 for controlling the up-and-down movement of the support block 220 is installed at the lower end of the support block 220. A U-shaped locking block 240 for locking the first connecting ring 100 in conjunction with the limiting slider 130 is installed on one side of the support block 220. A positioning groove 134 is provided on the side of the limiting slider 130 for positioning the limiting slider 130 in conjunction with the U-shaped locking block 240. One end of the U-shaped locking block 240 is located at the lower end of the support block 220. When the support block 220 moves downward, it drives the U-shaped locking block 240 to rotate, so that the other end of the U-shaped locking block 240 can be inserted into the cavity of the positioning groove 134 to lock the limiting slider 130.

[0034] The upper end of the support block 220 is provided with a second slide groove 221 for the ball 133 to slide, and the second slide groove 221 and the first slide groove 212 are aligned. A screw 222 is fixedly installed in the middle of the lower end of the support block 220, and a limit rod 223 is fixedly installed in the lower end of the support block 220. The inside of the fixing ring 210 is provided with a groove for the limit rod 223 to move up and down, so that the support block 220 can only move up and down.

[0035] The power assembly 230 includes a threaded sleeve 231 for cooperating with the screw 222 to control the support block 220 to move up and down. The threaded sleeve 231 is sleeved on the outside of the screw 222. A gear 232 is fixedly installed at the lower end of the threaded sleeve 231. A rotating rod 233 is fixedly installed at the middle of the bottom end of the gear 232. A regular hexagonal block 234 is fixedly installed at the bottom end of the rotating rod 233 to facilitate the rotation of the rotating rod 233. Four power assemblies 230 are installed in the middle of the second connecting ring 200, and only one power assembly 230 is equipped with the regular hexagonal block 234. A gear ring 250 is installed inside the fixing ring 210 for cooperating with the gear 232 to control the rotation of multiple power assemblies 230. Due to the setting of the gear ring 250, only the rotation of the regular hexagonal block 234 is needed to drive the four power assemblies 230 to rotate synchronously, so as to control the four support blocks 220 to move up and down synchronously.

[0036] A limiting rod 241 is installed in the middle of the U-shaped locking block 240, and a telescopic rod 242 for pushing the U-shaped locking block 240 is installed at the lower end of the U-shaped locking block 240. When the support block 220 moves upward, the telescopic rod 242 pushes the lower end of the U-shaped locking block 240, so that the upper end of the U-shaped locking block 240 moves away from the cavity of the positioning groove 134, thereby contacting the locking of the limiting slider 130, and the first connecting ring 100 can be disassembled.

[0037] The first connecting ring 100 is fixedly installed at the bottom of the storage chamber 10 and the bottom of the combustion chamber 20, and the second connecting ring 200 is fixedly installed at the top of the combustion chamber 20 and the top of the discharge chamber 30. When assembling the combustion chamber 20 and the discharge chamber 30, the positioning block 110 is inserted into the cavity of the positioning groove 211. At this time, the limiting slider 130 is above the fixing ring 210, and the ball bearing 133 is in the cavity of the sliding groove 212. By rotating the first connecting ring 100, the positioning block 110 moves to the side closer to the sliding groove 212, and the limiting slider 130 moves synchronously to the upper end of the support block 220. The regular hexagonal block 234 is then rotated using a wrench. The rotating rod 233, in conjunction with the gear 232, drives the gear ring 250 to rotate, causing the four power components 230 to rotate synchronously. This allows the screw sleeve 231, in conjunction with the screw 222, to drive the support block 220 to move downwards. While the first connecting ring 100 and the second connecting ring 200 are in contact with each other, the U-shaped locking block 240 is inserted into the cavity of the positioning groove 134, and, in conjunction with the limiting slider 130, locks the storage chamber 10. The combustion chamber 20 and the storage chamber 10 can be assembled in the above manner.

[0038] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
