Description

Technical Field

[0001] This utility model relates to the field of butterfly valve seat technology, and in particular to a metal-sealed butterfly valve seat forming device. Background Technology

[0002] A butterfly valve is a simple regulating valve used for on / off control of low-pressure pipeline media. The valve seat is a key valve component, used to support and seal the valve core. Butterfly valve seats can be classified by material into metal seats and rubber seats; metal seats are typically formed using stamping.

[0003] During the stamping process of existing metal butterfly valves, it is difficult to remove the valve seat from the lower die after stamping. If the removal process is too forceful, it can damage the valve seat and affect its sealing performance. Utility Model Content

[0004] The purpose of this invention is to provide a metal sealing butterfly valve seat forming device to solve the problem mentioned in the background art that, during the stamping production of existing metal butterfly valve seats, it is difficult to remove them from the lower die after stamping. When the removal process is too forceful, it can lead to damage to the butterfly valve seat, thereby affecting its sealing performance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a metal-sealed butterfly valve seat forming device, comprising:

[0007] A stamping assembly, the stamping assembly including a stamping press;

[0008] The movable component includes a slide, a telescopic spring, a slider, a first fixed shaft, a connecting rod, a second fixed shaft, a fixed block, and a movable ring. The slide is fixedly connected to the upper perimeter of the press, the telescopic spring is fixedly connected to one side of the slide, the slider is slidably connected to the inside of the slide, the first fixed shaft is fixedly connected to the upper interior of the slider, one end of the connecting rod is rotatably connected to the outer surface of the first fixed shaft, the second fixed shaft is rotatably connected to the interior of the other end of the connecting rod, the fixed block is fixedly connected to the outer side of the second fixed shaft, and the movable ring is fixedly connected to one side of the fixed block.

[0009] Furthermore, the stamping assembly also includes a lower die, a hydraulic rod, a mounting plate, and an upper die. The lower die is fixedly connected to the upper end of the stamping machine, the hydraulic rod is fixedly connected to the lower end of the upper part of the stamping machine, the mounting plate is fixedly connected to the lower end of the hydraulic rod, and the upper die is fixedly connected to the lower end of the mounting plate.

[0010] Furthermore, the other end of the telescopic spring is fixedly connected to the outer side of the slider, and the movable ring is slidably connected to the outer side of the lower mold.

[0011] Furthermore, the connecting rod is in an inclined state, and both ends of the connecting rod have hollow structures opened relative to the first fixed axis and the second fixed axis, respectively.

[0012] Furthermore, the height of the fixed block is less than the height of the movable ring, and the fixed block is located at the center of the outer side of the movable ring.

[0013] Furthermore, it also includes a protective assembly, which includes a first baffle, a support rod, a torsion spring, and a second baffle. The first baffle is fixedly connected to the bottom perimeter of the mounting plate, the support rod is fixedly connected to the inner side of the lower end of the first baffle, the torsion spring is fixedly connected to the inner side of the lower end of the support rod, and the second baffle is rotatably connected to the outer surface of the support rod.

[0014] Furthermore, the other end of the torsion spring is fixedly connected to the outer side of the second baffle, and the lower end of the first baffle has an L-shaped hollow structure.

[0015] Furthermore, the lower end of the second baffle extends beyond the lower end of the upper mold.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] I. This utility model, by setting a movable component, when the upper die moves downward to press the metal butterfly valve seat, the upper die drives the movable ring to move downward, and the movable ring moves downward to drive the fixed block to move downward, so that the fixed block drives the connecting rod to rotate outward through the second fixed shaft, and the connecting rod drives the slider to move inside the slide groove through the first fixed shaft and drives the telescopic spring to compress. When the upper die moves upward, the movable ring is reset under the action of the telescopic spring, thereby pushing the metal butterfly valve body upward, making it easy to remove the metal butterfly valve seat.

[0018] II. Based on the first beneficial effect, by setting up protective components, when the mounting plate moves the upper mold downward, the mounting plate moves the first baffle downward. The first baffle moves the second baffle downward through the support rod. When the bottom end of the second baffle contacts the upper end of the connecting rod, the second baffle rotates outward along the support rod. This allows the first and second baffles to block the outer sides of the upper and lower molds during the stamping process. Furthermore, the outward rotation of the second baffle pushes out any items or people that accidentally enter the lower mold position. Attached Figure Description

[0051] When the second baffle 34 rotates outward, the second baffle 34 causes the torsion spring 33 to deform and generate elastic force.

[0052] Working principle: When the mounting plate 14 drives the upper mold 15 to move downward to press the metal butterfly valve seat, the mounting plate 14 drives the first baffle 31 to move downward.
