Description

Technical Field

[0001] This utility model relates to the field of valve core processing technology, and in particular to a medical valve core flanging mechanism. Background Technology

[0002] Many valve components, such as valve cores, require flanging processing. The flanging process for valve components refers to deforming the edge of a workpiece using specific molds and processing equipment to form a straight wall or flange of a certain height. For example, Chinese patent CN221493808 U discloses a flanging device for a circular valve flange. It has a support base at the top of a rotating shaft, a side support base below the top support base, and a swing seat in conjunction with the side support base. The swing seat has a fixed wheel assembly, a pressing wheel assembly, and a pressing drive device that allows the two to be combined or separated. This device clamps the circular valve plate on both sides of the circular valve using the fixed wheel assembly and the pressing wheel assembly. When the circular valve rotates, the clamped plate moves from a vertical to a horizontal position through an arc-shaped guide groove, thus achieving the flanging process.

[0003] However, the above devices are only for the flanging operation of round valve flanges and adopt the side extrusion flanging method. They are not suitable for valve cores, especially for the flanging processing and production of medical valve cores. There is currently no suitable equipment.

[0004] Therefore, there is currently a lack of equipment that can ensure the stability of valve core flanging. After analyzing the existing technical means, this utility model proposes a medical valve core flanging mechanism. Utility Model Content

[0005] To address the above deficiencies, this utility model provides a medical valve core flanging mechanism, which ensures the stability of valve core flanging by establishing a processing device that includes a spreading mechanism and a flanging unit.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A medical valve core flanging mechanism, comprising:

[0008] The pressing unit has a pressure plate that is driven by the first cylinder to press down the valve core product to be processed;

[0009] The spreading mechanism is located above the pressing unit and is driven to move up and down by the lifting component. The spreading mechanism includes a finger cylinder and several opening and closing components. The opening and closing components move outward synchronously to spread and enlarge the outer edge of the valve core product to be processed.

[0010] The flange unit includes a third cylinder and a release plate driven by the cylinder, the release plate being horizontally positioned between the pressing unit and the spreading mechanism.

[0011] The technical means of the above technical solutions, in specific implementation, can form a series of technical solutions, including:

[0012] The lifting assembly includes a second cylinder.

[0013] Each opening and closing component of the spreading mechanism is driven by the finger cylinder to move outward or inward simultaneously until all the opening and closing components are closed together.

[0014] The fixed end of the opening and closing component is connected to the edge of the outer circumference of the finger cylinder.

[0015] During the actual processing, the finger cylinder drives four opening and closing components to fit into the valve core of the product, and then the outer edge of the valve core expands outward.

[0016] In addition, once the pressure plate is in position, the second cylinder drives the spreading mechanism to descend.

[0017] The pressure plate and release plate should be arranged in parallel during assembly.

[0018] During actual assembly, the valve core product to be processed is located inside the valve core processing and fixing position.

[0019] This utility model's technical solution, through the reasonable configuration of the corresponding components of the spreading mechanism, the flanging unit, and the pressing unit, includes the spreading mechanism descending to cause the finger cylinder to drive four opening and closing components to fit into the valve core of the product, causing the opening and closing components to open and expand the valve core, and the valve core to move away from the plate, thereby pressing down and pushing down the expanded side of the valve core. This enables the medical valve core product to complete the flanging operation and ensures the stability of the valve core flanging process. Attached Figure Description

[0048] The purpose of the medical valve core flanging mechanism implemented in this utility model is to ensure the stability of the medical valve core flanging process.

[0049] like Figure 1-2 , Figure 16 As shown, the medical valve core flanging mechanism implemented by this utility model firstly includes a pressing unit for bringing the product to a fixed processing position. The pressing unit is equipped with a pressure plate 2, which is positioned above the product fixing seat. The outer end of the pressure plate 2 is connected to the first cylinder 1 so that when the work starts, the first cylinder 1 can drive the pressure plate 2 to perform a pressing operation on the valve core processing fixing position 3 product.

[0050] like Figure 1-2 , Figure 9-10 As shown, the medical valve core flange mechanism implemented in this utility model has an opening mechanism above the pressing unit, which is driven to move up and down by a lifting unit. The lifting unit is driven by a second cylinder 4. The opening mechanism includes a finger cylinder 5 and several opening and closing components 10. Preferably, four opening and closing components 10 are used. The lower end of each opening and closing component 10 is connected to the driving end of the finger cylinder 5, so that the four opening and closing components 10 can be driven by the finger cylinder 5 to move outward simultaneously or from the outside to the inside until the four opening and closing components 10 are closed together. The opening and closing states of the opening and closing components 10 can be referred to Figure 9-10 .

[0051] like Figure 1-2 As shown, in the medical valve core flanging mechanism implemented by this utility model, a release plate 7 is further provided between the pressing plate 2 and the finger cylinder 5, and this release plate is connected to the third cylinder 6.

[0052] like Figure 1-8 As shown, in the medical valve core flanging mechanism implemented by this utility model, when the equipment starts working, the first cylinder 1 drives the pressure plate 2 to the valve core processing and fixing position 3 to press down the product. Its working state can be referred to Figure 1-2 As shown; after positioning, the second cylinder 4 begins to drive the opening mechanism to descend, that is, the finger cylinder 5 drives the four opening and closing components 10 to fit into the valve core of the product, and causes the opening and closing components 10 to open and expand the valve core. Its working state can be referred to Figure 3-6 As shown; after being expanded, the third cylinder 6 drives the release plate 7 to move, pressing down and pushing the expanded side of the valve core, thereby achieving the flipping of the valve core. Its working state can be referred to Figure 7-8 As shown, another Figure 11-15 As shown, by comparing the structures of the valve core 8 to be flipped and the valve core 9 that has been flipped, it can be seen that the medical valve core product can complete the flipping operation.

[0053] The technical solution implemented by this utility model mainly proposes to provide support for the flanging operation of medical valve cores by designing a valve core flanging device. Due to different design and application requirements, there are no mandatory requirements for the specific selection of cylinder models, opening and closing component dimensions, etc., used in practice, as these alternatives are not closely related to the technical solution implemented by this utility model. Those skilled in the art can refer to existing conventional technical means for selection.

[0054] In the description of this specification, the terms "connection", "set", "have", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] The above description of the embodiments is intended to enable those skilled in the art to understand and apply them. It is obvious to those skilled in the art that they can easily make various modifications to these examples and apply the general principles described herein to other embodiments without creative effort. Therefore, the protection scope of this utility model is not limited to the above situations.
