Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment manufacturing technology, specifically to a sterilization chamber cylinder port structure and forming device. Background Technology

[0002] As a key piece of equipment in industries such as medical and food processing, the sealing performance and structural strength of the sterilization chamber's cylindrical port directly affect the sterilization effect. Traditional sterilization chamber cylindrical ports generally employ a flange welding structure, where independently machined flange rings are fixed to the end of the cylinder through welding. However, this method suffers from low material utilization of the flange rings, resulting in significant waste; the flange rings require welding to both the inside and outside of the cylinder, leading to a large amount of welding; and the ports are prone to deformation, necessitating auxiliary welding deformation correction and non-destructive testing of the welds, increasing manufacturing costs. To address these issues, this application proposes a cylindrical port structure integrally formed through plastic deformation and a dedicated forming device, achieving weld-free processing of the port flanges, significantly improving production efficiency and reducing manufacturing costs. Utility Model Content

[0003] To achieve the above objectives, the present invention provides the following technical solution. A sterilization chamber cylindrical port structure includes an L-shaped flange integrally formed by plastic deformation at the end of the cylindrical body, the L-shaped flange including a horizontal flange and a vertical fold.

[0004] The horizontal flange is an annular plane that extends radially outward from the end of the cylinder. The vertical fold is a ring-shaped vertical wall that bends downwards axially from the outer edge of the horizontal fold. A forming device for the end structure of a sterilization chamber cylinder includes a lower mold assembly for positioning the cylinder and an upper mold assembly for processing the end. The upper mold assembly is provided with three sets of processing molds. The upper mold assembly can be raised, lowered, and horizontally displaced relative to the lower mold assembly to adjust the relative position of the three sets of processing molds with the lower mold assembly, so as to realize the flaring, bending, and forming of the end of the cylinder.

[0005] The lower mold assembly includes a support mechanism and a positioning mechanism. The support mechanism can drive the cylinder to rotate around its own axis, specifically including a servo motor-driven rotating platform; the positioning mechanism is located in the central area of ​​the rotating platform and consists of a central positioning component and an annular limiting component, which are coaxially arranged to form an annular positioning gap, the width of which is adapted to the cylinder wall thickness. The upper mold assembly includes a drive unit and a displacement unit. The drive unit uses a hydraulic cylinder to drive the processing mold to lift and lower; the displacement unit includes a lead screw-driven sliding seat, which can drive the upper mold assembly to move horizontally and adjust the position of the processing mold to complete different processes. The three sets of processing molds include: Flaring die: It has a tapered working surface and is used to radially flare the end of the cylinder to a preset diameter; Bending die: It has a columnar working surface and is used to bend the flared end to form a 90° horizontal flange; Forming mold: includes a movable mold body and a drive cylinder. The movable mold body is driven by the cylinder to achieve horizontal displacement, which is used to bend the outer edge of the horizontal flange. In conjunction with the rotating platform, the cylinder body is driven to rotate 360 ​​degrees to complete the final bending and forming. The working process of the molding device is as follows: Material loading and positioning: Insert the cylinder into the annular positioning gap of the lower mold assembly; Flaring process: The flaring die of the upper die assembly is moved to the top of the cylinder by the screw drive, and the hydraulic cylinder drives the flaring die to descend. The radial extrusion of the conical working surface causes plastic deformation at the end of the cylinder. Bending process: The bending die moves to the top of the cylinder, the bending die descends and presses against the flared end, and while the rotating platform drives the cylinder to rotate, the end is bent outward in the radial direction to form a horizontal flange. Forming process: The movable mold moves and descends to the side of the cylinder port, the drive cylinder pushes the movable mold to move horizontally, and bends the outer edge of the flange downward to form a vertical flange. The rotating platform rotates synchronously to ensure that the flange is formed evenly. Compared with the prior art, the present invention has the following beneficial effects: Improved material utilization: By eliminating the independent flange ring and forming the cylinder through plastic deformation of the cylinder material itself, the material utilization rate is significantly improved; Reduced processing costs: Eliminating processes such as welding, flaw detection, and straightening reduces manufacturing costs; Improved production efficiency: Compared to welding, production efficiency is significantly improved.
