Description

Technical Field

[0001] This utility model relates to the field of steel cylinder production and processing technology, and in particular to a steel cylinder necking and forming equipment. Background Technology

[0002] The cylinder neck is the opening on the cylinder used for loading and releasing gas. During the production and processing of cylinders, the cylinder neck needs to be narrowed. Most existing processing methods use induction heating coils in conjunction with stamping dies. The induction heating coil is responsible for heating the cylinder neck to improve the plasticity of the steel, reduce deformation resistance, and reduce internal stress during processing.

[0003] In the existing technology, when processing the necking of steel cylinders, the cylinder neck is usually heated first using an induction heating coil, and then the induction heating coil is removed and the heated cylinder neck is stamped using a stamping die. This process is inefficient and the disassembly and assembly of the steel cylinders are all done manually, which is very inconvenient in actual use.

[0004] Therefore, it is necessary to invent a cylinder necking forming device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cylinder necking and forming equipment that can simultaneously perform multiple cylinder feeding, heating, necking, and unloading operations, effectively improving processing efficiency. In addition, after the cylinder moves to the unloading station, gravity can be used to actively output the cylinder, eliminating the need for manual unloading. This makes it more convenient in actual use and solves the problem mentioned in the background art that the processing efficiency of cylinder necking and forming is low, and the disassembly and assembly of cylinders are all done manually, which is too inconvenient in actual use.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a cylinder necking forming device, comprising:

These drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification.

[0024] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0025] Figure 1 This is a schematic diagram of the overall structure of a cylinder necking forming device according to one embodiment of the present disclosure.

[0026] Figure 2 This is a schematic diagram of the cylinder circulation mechanism 1 of a cylinder necking forming device according to one embodiment of the present disclosure.

[0027] Figure 3 This is a schematic diagram of the bottle neck heating mechanism 2 and the pressure forming mechanism 3 of a cylinder necking forming device according to one embodiment of the present disclosure.

[0028] like Figures 1-3 As shown, the cylinder necking forming equipment disclosed herein may include components such as a cylinder circulation mechanism 1, a cylinder neck heating mechanism 2, and a pressure forming mechanism 3.

[0029] like Figure 2As shown in this disclosure, the cylinder circulation mechanism 1 includes a workbench 11. A material discharge chute 12 is provided on the top left side of the workbench 11, and a guide frame 13 is fixedly provided on the bottom left side. A fixed frame A14 is fixedly provided on the top of the workbench 11. A rotating disk 15 is rotatably provided on the inner side of the fixed frame A14 through a bearing. Multiple positioning slots 16 for positioning the cylinders to be processed are evenly provided along the vertical direction on the top edge of the rotating disk 15. Any one of the positioning slots 16 is adapted to the cylinder to be processed. A rotating shaft 17 is fixedly provided on the inner side of the positioning slot 16. A stepper motor 18 that is drivenly connected to the rotating shaft 17 is fixedly provided at the bottom center of the workbench 11.

[0030] Therefore, the steel cylinder to be processed is vertically inserted into the adjacent positioning slot 16 for positioning from the front of the device. Then, the stepper motor 18 drives the rotating disk 15 to rotate via the rotating shaft 17, thereby causing the rotating disk 15 to move the steel cylinder from the loading station to the heating station through the positioning slot 16. Subsequently, the bottle neck heating mechanism 2 heats the bottle neck. During this process, the steel cylinder to be processed is inserted into the adjacent positioning slot 16 again. Then, the stepper motor 18 drives the rotating disk 15 to move again, thereby moving the heated steel cylinder to the necking station for pressure forming. The cylinder 3 performs necking processing, while simultaneously moving the newly inserted cylinder to the heating station for heating. As the rotating disk 15 continues to rotate, the processed cylinder moves above the discharge chute 12, and then, under the action of gravity, moves out from the inside of the positioning slot 16 and falls into the inside of the guide frame 13 for output. Compared with the existing technology, multiple cylinders can be loaded, heated, necked, and discharged simultaneously, effectively improving processing efficiency. In addition, after the cylinder moves to the discharge station, gravity can be used to actively discharge the cylinder, eliminating the need for manual cylinder discharge, making it more convenient in actual use.

[0031] It should be noted that the input terminal of the stepper motor 18 is connected to a control system that controls its rotation angle. The stepper motor 18 and its corresponding control system are both existing technologies, so this application will not elaborate on them here.

[0032] like Figure 3 As shown, in a preferred embodiment, the bottle mouth heating mechanism 2 includes a fixed frame B21 fixedly disposed on the right side of the workbench 11 and the fixed frame A14. An electric push rod 22 is fixedly disposed on the top of the fixed frame B21. The output shaft of the electric push rod 22 slides through the fixed frame B21 in the vertical direction and is fixedly connected to a lifting block 23. An induction heating coil 24 located directly above the adjacent positioning slot 16 is fixedly disposed on the left side of the lifting block 23.

[0033] Therefore, after the gas cylinder is moved to the heating station, the electric push rod 22 drives the induction heating coil 24 to move down through the fixed frame B21 until the induction heating coil 24 is sleeved on the outside of the gas cylinder mouth. Then, the induction heating coil 24 is energized, and the energized induction heating coil 24 continuously heats the gas cylinder mouth.

[0034] like Figure 3 As shown in this disclosure, the pressure forming mechanism 3 includes a fixed frame C31 fixedly disposed on the worktable 11 and the rear side of the fixed frame A14. A hydraulic cylinder 32 is fixedly disposed on the top of the fixed frame C31. The output shaft of the hydraulic cylinder 32 slides through the fixed frame C31 in the vertical direction and is fixedly connected to a pressure block 33. A frustum-shaped forming groove 34 is opened at the bottom end of the pressure block 33.

[0035] Thus, after the cylinder moves to the necking station, the hydraulic cylinder 32 drives the pressure block 33 to move continuously downward. When the pressure block 33 moves downward, it drives the frustum-shaped forming groove 34 to fit onto the outside of the heated cylinder neck. As the hydraulic cylinder 32 continues to descend, the cylinder neck is squeezed inward along the inner wall of the frustum-shaped forming groove 34, and finally the necking is completed.

[0036] It should be noted that the hydraulic cylinder 32 is connected to a hydraulic drive unit that controls the extension and retraction of its output shaft. Both the hydraulic cylinder 32 and the hydraulic drive unit are existing technologies, so they will not be described in detail here.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
