[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figure 1 , Figure 5 , the present utility model provides a thermally welded cylinder body for a sealed packaging cylinder, including a hollow cylinder body 1. A cylinder bottom 2 is hot-melt welded to the bottom of the cylinder body 1. A cylinder cover 3 is threadedly connected to the top of the cylinder body 1. A reinforcement member 4 is provided inside the cylinder body 1. The outer edge of the reinforcement member 4 is connected to the inner wall of the cylinder body 1. This connection can be a fixed connection or an abutting connection, and is used to divide and support the inside of the cylinder body 1. Through the setting of the reinforcement member 4, the inside of the cylinder body 1 will be divided into multiple fan-shaped spaces to realize the classified placement of ammunition. Secondly, due to the support of the edge of the reinforcement member 4, the compressive strength of the cylinder body 1 can be improved;
[0027] Specifically, the welding method between the cylinder body 1 and the cylinder bottom 2 is as follows: Place the cylinder bottom 2 and the cylinder body 1 on a preheated plastic welding machine. Clean the cylinder bottom 2. Connect the cylinder body 1 and the welding tooling into one body with screws and tighten. Clean the cylinder body 1 and place it on the chuck. The welding port of the cylinder body 1 should be as close to the chuck as possible. Adjust the coaxiality with the cylinder bottom 2 and tighten;
[0028] Turn on the milling cutter switch, place the milling cutter into the machine frame, the oil cylinder works, close the cylinder body 1 and the cylinder bottom 2, and apply pressure at the same time to ensure continuous cutting. The cutting amount should not be greater than the specified value. After the action is completed, the oil cylinder retracts and the milling cutter is placed back in place;
[0029] Close the cylinder body 1 and the cylinder bottom 2, adjust the offset, place the positioning block on the cylinder bottom 2. Before the heating plate is placed into the positioning block, start the oil cylinder and move forward to press the end face of the cylinder body 1 against the heating plate. Heat the welding surface of the cylinder body 1 on one side. When the specified minimum hemming is reached, quickly remove the positioning block. The oil cylinder moves forward to press the cylinder body 1 and the cylinder bottom 2 against the heating plate at the same time, and heat the welding surfaces of the cylinder body 1 and the cylinder bottom 2 simultaneously. When the specified minimum hemming is reached, the oil cylinder retreats, withdraw the heating plate, the oil cylinder moves forward to close the cylinder body 1 and the cylinder bottom 2, and keep the pressure until the hemming temperature reaches the specified value, then the connection can be completed.
[0030] As Figure 3 , Figure 6 shown, the reinforcement member 4 of this embodiment is composed of six reinforcing plates 41 arranged in an equally spaced circular pattern. The reinforcing plate 41 has a square structure, and its height is adapted to the height of the cylinder body 1. When it is placed inside the cylinder body 1, its two ends are flush with the two end faces of the cylinder body 1. It should be particularly noted here that the specific number of the reinforcing plates 41 can be selected according to actual needs. However, the more the reinforcing plates 41, although the compressive strength of the cylinder body 1 will be higher, the internal space of the cylinder body 1 will be smaller. To ensure a relative balance, therefore, the preferred number of the reinforcing plates 41 is 4 - 6;
[0031] As Figures 2 - 4 shown, in order to ensure the sealing performance inside the cylinder body 1, a second gasket 6 is provided inside the cylinder cover 3, and a first gasket 5 is provided inside the cylinder bottom 2. The first gasket 5 and the second gasket 6 are made of elastic soft materials such as rubber, silicone, polytetrafluoroethylene, etc., and can be selected adaptively according to actual needs. When the cylinder cover 3 and the cylinder bottom 2 are respectively connected to the two ends of the cylinder body 1, the first gasket 5 and the second gasket 6 can respectively abut against the two ends of the cylinder body 1, so that a sealed structure is formed inside the cylinder body 1 to meet the requirements for ammunition storage.
[0032] Finally, it should be noted that: the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
