Description

Technical Field

[0001] The utility model relates to the technical field of steel bottle molding, in particular to a double-station screw-down compression device for thick-walled steel bottles. Background Art

[0002] Thick-walled cylinders, generally referring to steel cylinders with thicker walls, are widely used in various fields, especially in situations where they need to withstand high pressure, high stress, or special working environments.

[0003] Spinning and compression of steel cylinder openings is an important process in the manufacturing process of steel cylinders. It mainly uses spinning technology to compress and shape the opening part of the steel cylinder to achieve the required shape and size requirements.

[0004] The utility model patent with patent authorization announcement number CN207026347U discloses a necking device for steel cylinder necking molding. The necking device can simultaneously extrude and neck the steel cylinder blank through a first hydraulic device and a second hydraulic device, which can not only improve the necking efficiency, but also improve the yield of the steel cylinder necking.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that the steel cylinder is pressed down by the cylinder to squeeze and fix the steel cylinder blank through the pressing piece, and the motor drives the steel cylinder to rotate. When the first hydraulic device and the second hydraulic device clamp the steel cylinder, the steel cylinder will not be able to rotate smoothly, causing the first hydraulic device and the second hydraulic device to slip on the surface of the steel cylinder and unable to rotate around the steel surface, resulting in poor spinning effect.

[0006] Therefore, it is necessary to invent a double-station screw-down port device for thick-walled steel cylinders to solve the above problems. Utility Model Content

[0023] For descriptive purposes, this disclosure may use spatially relative terms such as "below," "beneath," "beneath," "below," "above," "upper," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be oriented "above" the other component or feature. Thus, the exemplary term "below" can encompass both "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein interpreted accordingly.
