Description

Technical Field

[0001] The utility model belongs to the technical field of extrusion molding devices, and in particular relates to a cylinder extrusion molding device for a composite hydrogen pressure container. Background Art

[0002] Composite hydrides are compounds composed of hydrogen and two or more other elements. Common composite hydrides include lithium aluminum hydride and sodium borohydride. Composite hydrogen generally uses corresponding pressure vessels in its production. Pressure vessels refer to closed devices that contain gas or liquid and bear a certain pressure. Pressure vessels generally consist of a cylinder and two end caps. The cylinder generally needs to be extruded during production, so an extrusion molding device is used. However, some existing extrusion molding devices often have certain deficiencies when used and need to be improved.

A plurality of forming holes are arranged in an annular manner on the upper surface of the lower forming table. An upper forming table is provided above the lower forming table. The lower surface of the upper forming table is provided with a forming column extending vertically downward. The position of the forming column corresponds to the position of the forming hole, and the lower end of the feed pipe points to the forming hole. The extrusion molding device of this utility model can produce columnar materials with high efficiency and low cost.

[0004] However, although the above technical solution can extrude columnar materials when used, the material is still inside the forming hole after the extrusion is completed. It is difficult for the staff to remove it in time, and there are no corresponding tools to remove it, which leads to a delay in the subsequent removal of the columnar material, thereby reducing the progress of the subsequent extrusion molding work and having certain limitations when used.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] See also Figures 1 to 4As shown, a cylindrical extrusion molding device for a composite hydrogen pressure vessel includes a base plate 1, the top of the base plate 1 is fixedly connected to a support frame 2, the top of the support frame 2 is fixedly connected to a top plate 3, a molding cylinder 4 is arranged above the base plate 1, the bottom of the molding cylinder 4 is connected to a blocking cover 5, the inside of the blocking cover 5 is fixedly connected to a molding column 6, one side of the inner top wall of the top plate 3 is fixedly connected to a first hydraulic rod 7, the output end of the first hydraulic rod 7 is fixedly connected to an extrusion plate 8, the other side of the inner top wall of the top plate 3 is fixedly connected to a second hydraulic rod 9, the output end of the second hydraulic rod 9 is fixedly connected to a push plate 10, the top end of one side of the support frame 2 is fixedly connected to two servo motors 11, and the output end of the servo motor 11 is fixedly connected to a threaded rod 12. Through the setting of the support frame 2, the top plate 3 can be installed and fixed; through the setting of the forming cylinder 4, the material for making the pressure vessel can be placed inside it; through the setting of the forming column 6, it can be inserted into the forming cylinder 4 to form a cylinder; through the setting of the first hydraulic rod 7 and the extrusion plate 8, a certain amount of material can be added to the inside of the forming cylinder 4 and then extruded; through the setting of the second hydraulic rod 9 and the push plate 10, the material inside the forming cylinder 4 is formed to facilitate subsequent extrusion; through the setting of the servo motor 11, it provides a certain driving force for the rotation of the threaded rod 12.

[0026] The threaded rod 12 has a threaded sleeve threaded through it, a sliding block 13 is fixedly connected to the surface of the threaded sleeve, and a connecting tube 14 is fixedly connected to the surface of the sliding block 13. The arrangement of the threaded rod 12 and the threaded sleeve allows the sliding block 13 to slide, and the arrangement of the connecting tube 14 allows the drive motor 15 to be fixedly connected to the sliding block 13.

[0027] The end of the connecting tube 14, away from the sliding block 13, is fixedly connected to a drive motor 15. The output end of the drive motor 15 is fixedly connected to a transmission rod 16. The surface of the transmission rod 16 extends through the interior of the sliding block 13 and is fixedly connected to the surface of the forming tube 4. The drive motor 15 provides a certain driving force for the rotation of the transmission rod 16. It should be noted that the surface of the transmission rod 16 is rotatably disposed inside the sliding block 13 and extends therethrough, and the end of the transmission rod 16 is fixedly connected to the surface of the forming tube 4.

[0028] Two sliding grooves 17 are provided inside the support frame 2, and the sliding block 13 slides inside the sliding grooves 17. Through the opening of the sliding grooves 17, the sliding block 13 can slide inside the sliding grooves 17.

[0029] An annular groove 18 is formed inside the forming cylinder 4, and a connecting ring 19 is threadedly connected to the inner side wall of the annular groove 18. The connecting ring 19 is fixedly connected to the top of the blocking cover 5. The annular groove 18 allows the connecting ring 19 to be screwed into the inside, so that the bottom of the forming cylinder 4 is blocked and sealed, which facilitates better extrusion of subsequent materials.

[0030] A control panel is fixedly connected to one side of the support frame 2 , and the control panel is electrically connected to the first hydraulic rod 7 , the second hydraulic rod 9 , the servo motor 11 and the drive motor 15 , respectively.

[0031] Example 2:

[0032] See also Figure 1 、 Figure 2 and Figure 5 As shown, the inner side wall of the support frame 2 is slidably connected to a carrier plate 20, a buffer pad 21 is provided on the top of the carrier plate 20, five guide rods 22 are fixedly connected to the bottom of the carrier plate 20, and five buffer springs 23 are fixedly connected to the bottom of the carrier plate 20. The bottom end of the buffer spring 23 is fixedly connected to a damper 24, and the bottom of the damper 24 is fixedly connected to the top of the base plate 1. The arrangement of the carrier plate 20 allows the buffer pad 21 to be stably placed. The arrangement of the buffer pad 21 provides a preliminary buffering effect when the material inside the forming cylinder 4 falls downward after being extruded and formed. The arrangement of the guide rods 22 provides a certain guiding effect when the carrier plate 20 is extruded and lowered. The arrangement of the buffer springs 23 allows the carrier plate 20 to play a buffering role again when it is subjected to the extrusion force. The arrangement of the damper 24 reduces the extrusion force on the buffer spring 23 to prevent excessive speed.

[0033] The working principle of the present invention is as follows: the staff injects the material for making the cylinder into the interior of the forming cylinder 4 in advance, and then the staff controls the first hydraulic rod 7 to descend so that it squeezes the material inside the forming cylinder 4 until it is formed. At this time, the staff controls the servo motor 11 to start, and the output end of the servo motor 11 drives the threaded rod 12 to rotate, and the rotation of the threaded rod 12 drives the threaded sleeve to move forward, so that the sliding block 13 follows it to slide forward inside the sliding groove 17, and then the drive motor 15 moves with it. When the forming cylinder 4 moves to the bottom of the push plate 10, the staff controls the servo motor 11 to stop working, and at the same time the staff unscrews the blocking cover 5, so that the connecting ring 19 is separated from the annular groove 18. At the same time, the staff controls the drive motor 15 to start, and the drive motor 15 drives the forming cylinder 4 to move to the bottom of the push plate 10. The molding cylinder 4 rotates 180 degrees, and the angle of rotation driven by the driving motor 15 can be set in advance. Then the staff removes the blocking cover 5, and the molding column 6 is separated from the inside of the molding cylinder 4. Finally, the staff controls the driving motor 15 to rotate 180 degrees to keep the molding cylinder 4 in a vertical state. Then the staff controls the second hydraulic rod 9 to work, and the output end of the second hydraulic rod 9 drives the push plate 10 to descend until it pushes out the cylinder formed inside the molding cylinder 4. The pushed out cylinder falls on the buffer pad 21 to play a preliminary buffering effect. At the same time, the supporting plate 20 is squeezed downward, so that the buffer spring 23 and the guide rod 22 are squeezed, so that the extrusion force exerted on the supporting plate 20 is absorbed again, so that the impact force exerted on the molded cylinder is smaller, which plays a certain protective role on it.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
