The hot-top casting crystallizer fixture consists of a crystallizer, a casting water tank (matching the casting machine cover), a metal guiding and diversion system, a dummy head, a dummy head support platform (dummy head frame), an anti-tipping frame, etc. During the casting process, the liquid aluminum liquid is cooled to cast aluminum rods that meet the standards specified in the aluminum processing industry.

[0003] After the hollow tubes and aluminum rods are successfully cast, they need to be cut and trimmed: the cast hollow tubes are cut and trimmed as needed to ensure dimensional accuracy and a smooth surface.

[0004] The prepared aluminum alloy hollow tubes and aluminum rods can be used for different parts and components of hydrogen storage cylinders, such as cylinder bodies and connectors, to ensure that hydrogen storage cylinders can safely store and release hydrogen during use.

[0005] Traditional equipment for preparing aluminum alloy cast hollow tubes and aluminum rods for hydrogen storage cylinders may leave sharp or uneven cutting edges after the hollow tubes are cut, affecting the use and safety performance of the hollow tubes.

[0006] In summary, the existing technology lacks a technique for trimming the cut ends of certain hollow tubes. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the prior art by proposing a manufacturing process for aluminum alloy cast hollow tubes and aluminum rods for hydrogen storage cylinders.

Detailed Implementation

[0031] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] like Figures 1-8 The process for manufacturing a hollow aluminum alloy casting tube and aluminum rod for a hydrogen storage cylinder is shown. The process is carried out using the following equipment: the equipment includes a base 1, two positioning seats 2 are fixedly installed on the upper side of the base 1, a hollow tube 3 is placed between the two positioning seats 2, an adjustment mechanism 4 is provided on the base 1, a fixed frame 5 is fixedly installed on one side of the base 1, a rotating frame 6 is rotatably connected to the fixed frame 5, an adjustment frame 7 is slidably fitted on the rotating frame 6, an end face treatment mechanism 8 is rotatably connected to the adjustment frame 7, and side wall treatment mechanisms 9 are provided on the other two ends of the adjustment frame 7.

[0033] like Figure 3 As shown, a plurality of threaded rods 201 are rotatably connected to one side of the positioning seat 2 in a ring structure. A gear 202 is fixedly connected to the outer end of the threaded rod 201, and a positioning rod 203 is threadedly connected to the threaded rod 201. The positioning rod 203 performs the positioning function of the hollow tube 3.

[0034] like Figure 3 , Figure 4 As shown, the adjustment mechanism 4 includes two adjustment rings 401, with multiple handles 402 fixedly connected between them. Each adjustment ring 401 has a limiting groove 403, within which a limiting block 404 slides. The end of the limiting block 404 closest to the base 1 is fixedly connected to the base 1. A ring rack A405 is fixedly connected to the side of the adjustment ring 401 closest to the positioning seat 2, and the ring rack A405 meshes with a gear 202 for transmission. The adjustment mechanism 4 enables the simultaneous movement of multiple positioning rods 203.

[0035] like Figure 5 , Figure 6 As shown, a motor 601 is fixedly connected to one end of the rotating frame 6, which is connected to the fixed frame 5. A lead screw 602 is rotatably connected to the rotating frame 6, and a handle 603 is connected to one end of the lead screw 602. The lead screw 602 is threadedly connected to the adjusting frame 7. The lead screw 602 adjusts the position of the adjusting frame 7.

[0036] A transmission rod 604 is rotatably connected to the rotating frame 6. A transmission wheel 605 is fixedly connected to one end of the transmission rod 604. A ring rack B501 is fixedly connected to the fixed frame 5. The ring rack B501 meshes with the transmission wheel 605 to drive the transmission. The ring rack B501 drives the transmission rod 604 to rotate.

[0037] like Figure 7 As shown, the end face processing mechanism 8 includes an end face grinding roller 801, with a sliding sleeve 802 fixedly connected inside the end face grinding roller 801. The sliding sleeve 802 is rotatably connected to the adjusting frame 7 and slides against the outer wall of the transmission rod 604. Both ends of the sliding sleeve 802 are connected to gear discs 803. The gear discs 803 drive the side wall processing mechanism 9.

[0038] like Figure 7 , Figure 8 As shown, the sidewall processing mechanism 9 includes a sliding frame 901, which slides in conjunction with the adjusting frame 7. A spring 902 connects the sliding frame 901 and the adjusting frame 7. An inclined guide plate 903 is fixedly connected to the other end of the sliding frame 901. The inclined guide plate 903 facilitates the placement of the hollow tube 3's sidewall between two sidewall grinding rollers 904. The spring 902 causes the sidewall grinding rollers 904 to trim hollow tubes 3 of different thicknesses.

[0039] A side wall grinding roller 904 is rotatably connected to one end of the sliding frame 901 near the inclined guide plate 903. A universal joint A905 is fixed to one end of the side wall grinding roller 904, and a drive shaft 906 is fixed to the other end of the universal joint A905.

[0040] A transmission sleeve 907 is slidably fitted onto the outer wall of the drive shaft 906. The transmission sleeve 907 is rotatably connected to the adjusting frame 7. A universal joint B908 is connected to the other end of the transmission sleeve 907, and an adjusting wheel 909 is connected to the other end of the universal joint B908. The adjusting wheel 909 meshes with the gear disc 803 for transmission. The adjusting wheel 909 enables the side wall grinding roller 904 to rotate and adjust.

[0041] When it is necessary to prepare the aluminum alloy cast hollow tube 3 for hydrogen storage cylinder, the hot top casting crystallizer tooling is used for preparation. After the hollow tube 3 is prepared and cut, the hollow tube 3 is placed on the positioning seat 2. Then, the handle 402 drives the two adjusting rings 401 to rotate, so that the annular rack A405 on the adjusting ring 401 drives the threaded rod 201 connected to the gear 202 to rotate, so that the threaded rod 201 drives the positioning rod 203 to move and position the hollow tube 3.

[0042] Then, adjust the position of the adjusting frame 7 according to the size of the hollow tube 3. By rotating the lead screw 602, the lead screw 602 drives the adjusting frame 7 to adjust its position. Then push the hollow tube 3 so that the side wall of the hollow tube 3 is placed between the two side wall grinding rollers 904. At this time, under the action of the spring 902, the side wall grinding rollers 904 will be in close contact with the side wall of the hollow tube 3.

[0043] Then, the motor 601 drives the rotating frame 6 to rotate. At this time, under the action of the ring rack B501, the transmission rod 604 connected to the transmission wheel 605 will rotate. At this time, the transmission rod 604 will drive the end face grinding roller 801 connected to the sliding sleeve 802 to rotate and trim the end face of the hollow tube 3.

[0044] Simultaneously, the gear disc 803 connected via the sliding sleeve 802 drives the adjusting wheel 909 to rotate, which in turn drives the transmission sleeve 907 connected to the adjusting wheel 909 to rotate. This causes the transmission sleeve 907 to drive the universal joint A905 connected to the transmission shaft 906 to rotate, which in turn drives the side wall grinding roller 904 to rotate. This process trims the side wall of the cut end of the hollow tube 3, ensuring the quality of the end face of the hollow tube 3 and thus guaranteeing the sealing and strength of the welded or connected parts of the hydrogen storage tank.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
