Abstract
Description
Technical Field
[0001] This utility model relates to a device for flanges inside and outside the cylinder of a pressure vessel. Background Technology
[0002] Pressure vessel shell flange refers to the process of machining an inward or outward rolled edge structure at the end of the vessel, which is a key process for sealing connections or enhancing pressure resistance.
[0003] Traditional flanging uses separate molds and manual operation, which requires repeated disassembly and assembly of the molds and has low positioning accuracy, resulting in uneven stress on the cylinder and wrinkles. Although existing hydraulic flanging equipment increases the processing force, it cannot control the deformation of the inner and outer flanging at the same time, which is especially prone to crushing deformation for thin-walled containers. At the same time, the mold replacement process is complicated and time-consuming. Utility Model Content
[0004] The purpose of this invention is to provide a device for flanged inner and outer sides of a pressure vessel cylinder to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pressure vessel inner and outer flange device includes a base, a vessel clamping structure, a hydraulic station, a control platform, columns, a top plate, an extension plate, a driving hydraulic cylinder, and a flange mold. The vessel clamping structure is fixedly connected to the center of the top of the base. The hydraulic station is fixedly connected to the rear right side of the base. The control platform is fixedly connected to the front right side of the base. Two columns are fixedly connected at equal intervals to the rear top of the base. The top plate is fixedly connected between the tops of the two columns. The extension plate is fixedly connected to the center of the top plate. The driving hydraulic cylinder is fixedly connected to the inside of the front end of the extension plate. The flange mold is fixedly connected to the bottom of the driving hydraulic cylinder and slidably connected to the rear of the two columns.
[0006] Based on the above technical solution, the container clamping structure includes a positioning plate, an adjusting plate, and adjusting studs. The two positioning plates are fixedly connected at equal intervals at the center of the top of the base, and the two adjusting plates are threadedly connected to the inner side of the two positioning plates by two adjusting studs.
[0007] Based on the above technical solution, the flanging mold includes an upper mold, an upper mold sliding hole, a hydraulic cylinder fixing ring, a lower pressing protrusion, a lower mold, a container pre-reserved hole, a lower mold sliding hole, connecting columns, and a reciprocating spring. Two upper mold sliding holes are equidistantly opened at the rear of the upper mold. The hydraulic cylinder fixing ring is fixedly connected to the center of the top of the upper mold. The lower pressing protrusion is fixedly connected to the center of the bottom of the upper mold. A container pre-reserved hole is opened at the center of the lower mold. Two lower mold sliding holes are equidistantly opened at the rear of the lower mold. Four connecting columns are equidistantly fixedly connected to the bottom of the upper mold. The lower mold is sleeved between the four connecting columns. The reciprocating spring is placed outside the connecting columns and located between the upper mold and the lower mold.
[0008] Compared with the prior art, this utility model has the following advantages: This utility model improves processing accuracy and significantly reduces operation complexity through modular clamping mechanism and linkage mold design: the adjustable stud of the container clamping structure drives the adjustment plate to achieve radial adaptive locking of the cylinder, which avoids damage from traditional mechanical crushing and is compatible with containers of different diameters; in the flanging mold, the upper mold and the lower mold are elastically linked through the connecting column, and the reciprocating spring buffers the lower pressing protrusion to accurately control the flanging depth, which greatly reduces the deformation of thin-walled containers while achieving synchronous forming of inner and outer flanging.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0014] like Figure 1-3 As shown, a pressure vessel cylinder inner and outer flanging device includes a base 1, a container clamping structure 2, a hydraulic station 3, a control platform 4, columns 5, a top plate 6, an extension plate 7, a driving hydraulic cylinder 8, and a flanging mold 9. The container clamping structure 2 is fixedly connected to the center of the top of the base 1. The hydraulic station 3 is fixedly connected to the rear right side of the base 1. The control platform 4 is fixedly connected to the front right side of the base 1. Two columns 5 are fixedly connected at equal intervals to the rear top of the base 1. The top plate 6 is fixedly connected between the tops of the two columns 5. The extension plate 7 is fixedly connected to the center of the top plate 6. The driving hydraulic cylinder 8 is fixedly connected to the inside of the front end of the extension plate 7. The flanging mold 9 is fixedly connected to the bottom of the driving hydraulic cylinder 8 and slidably connected to the rear of the two columns 5.
[0015] The container clamping structure 2 includes a positioning plate 10, an adjusting plate 11, and adjusting studs 12. The two positioning plates 10 are fixedly connected at equal intervals at the top center of the base 1, and the two adjusting plates 11 are respectively threaded to the inner side of the two positioning plates 10 through two adjusting studs 12.
[0016] The flanging mold 9 includes an upper mold 13, an upper mold sliding hole 14, a hydraulic cylinder fixing ring 15, a lower pressing protrusion 16, a lower mold 17, a container pre-reserved hole 18, a lower mold sliding hole 19, connecting pillars 20, and a reciprocating spring 21. The upper mold 13 has two upper mold sliding holes 14 equidistantly spaced at the rear. The hydraulic cylinder fixing ring 15 is fixedly connected to the center of the top of the upper mold 13. The lower pressing protrusion 16 is fixedly connected to the center of the bottom of the upper mold 13. The lower mold 17 has a container pre-reserved hole 18 at its center. The two lower mold sliding holes 19 are equidistantly spaced at the rear of the lower mold 17. The four connecting pillars 20 are equidistantly fixedly connected to the bottom of the upper mold 13. The lower mold 17 is fitted between the four connecting pillars 20. The reciprocating spring 21 is placed outside the connecting pillars 20 and located between the upper mold 13 and the lower mold 17.
[0017] The working principle of this utility model is as follows: First, rotate the adjusting stud 12 to move the adjusting plate 11, so that the positioning plate 10 clamps the cylinder; the control platform 4 starts the hydraulic station 3, drives the hydraulic cylinder 8 to push the upper mold 13 down along the column 5; after the lower pressing protrusion 16 contacts the end face of the cylinder, it continues to apply pressure, and the lower mold 17 compresses the reciprocating spring 21 under the guidance of the connecting column 20 to form a reaction force; when the cylinder material enters the deformation cavity formed by the upper mold sliding hole 14 and the lower mold sliding hole 19, the inner and outer flanging is formed simultaneously; after completion, the hydraulic cylinder 8 is reset, and the reciprocating spring 21 resets the lower mold 17, thereby completing the separation of the workpiece.
[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
