Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve processing, in particular to a processing device for a butterfly valve plate. Background Art

[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for on-off control of low-pressure pipeline media. By changing the deflection angle of the butterfly valve disc, the flow of the medium can be controlled. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] During the manufacturing process of butterfly valve discs, drilling is required on the valve body. Currently, drilling is performed manually using a hydraulic press. However, this press can only apply pressure to the top of the disc. The contact between the hydraulic press and the valve generates a downward force, which can easily cause the disc to shift position. This can lead to low drilling accuracy, affecting the production quality of the butterfly valve and reducing work efficiency. To address this issue, we provide a processing device for butterfly valve discs. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] The existing technology has the problem of low precision of valve plate drilling, which affects the production quality of butterfly valves. This embodiment provides a processing device for butterfly valve plates. Figure 1-Figure 4 , which can quickly and accurately punch holes in the valve plate, thereby improving the efficiency of punching holes in the valve plate. The processing device for butterfly valve plates includes a top frame 2 fixedly mounted on the top of a base 1, a drilling mechanism 3 for cleaning debris is provided on the base 1 and the top frame 2, and a lifting and protection mechanism 4 for lifting the valve plate is provided on the base 1 and the top frame 2. The drilling mechanism 3 can not only stably punch holes in the valve plate, but also clean the debris generated by drilling. The lifting and protection mechanism 4 can lift the fixed valve plate, thereby applying pressure to the bottom end of the valve plate, making it possible to drill holes in the valve plate more accurately, and also having a certain effect of preventing debris from splashing.

[0025] In order to be able to drill the valve plate quickly and accurately and improve the drilling quality of the valve plate, the protective mechanism 4 includes a driving motor 41 installed at the side end of the base 1 and a fixed shell 44 installed on the base 1. The output end of the driving motor 41 is connected to a rotating plate 42, and a transmission rod 43 is fixedly installed on the side of the rotating plate 42. A lifting seat 45 adapted to the transmission rod 43 is slidably connected inside the fixed shell 44. The bottom end of the lifting seat 45 is connected to two groups of extrusion springs connected to the bottom end of the inner side of the base 1, through the extrusion springs, the lifting seat 45 has a reset function, and a placing plate 46 is fixedly installed on the top of the lifting seat 45. Two groups of clamping members 47 are movably installed on the top of the placing plate 46. The clamping member 47 is connected to the top of the placing plate 46 by bolts 48, which is convenient for quick disassembly and assembly of the clamping member 47, and can also be convenient for quick adjustment of its position. Bolts 48 are threaded on the clamping member 47, and a splash-proof component 401 that can prevent debris from splashing is provided on the top frame 2. The clamping parts 47 are fixed to the placement plate 46 by bolts 48, and the two sets of clamping parts 47 fix the valve plate. The rotating plate 42 is rotated by the operation of the driving motor 41, so that the transmission rod 43 lifts the lifting seat 45 along the inside of the fixed shell 44, and through cooperation with the drill 33, the valve plate can be drilled more accurately.

[0026] Because drilling will generate debris, in order to prevent the debris from splashing, the splash-proof assembly 401 includes a reduction motor 49 installed on the top of the top frame 2, a mounting plate 410 is fixedly mounted on the output end of the reduction motor 49, and a splash-proof cover 411 is fixedly mounted on the bottom end of the mounting plate 410. The width of the splash-proof cover 411 is greater than the width of the placement plate 46, which is convenient for better blocking the debris. The splash-proof cover 411 is made of a transparent material, which is convenient for the operator to observe the drilling process. During the drilling process, the speed reduction motor 49 is operated, and the splash-proof cover 411 is rotated to the front of the base 1 under the connection with the mounting plate 410, thereby preventing the debris from splashing.

[0027] Example 2

[0028] On the basis of Example 1, Figure 1-Figure 4 As shown, based on the current problem of low precision in valve plate drilling affecting the production quality of butterfly valves, some debris will be generated during the drilling of the valve plate. As the drilling continues, the debris is easily accumulated around the valve plate, which easily affects the production quality of the valve plate. Therefore, the device is also provided with a drilling structure with a debris cleaning function.

[0029] To ensure a more stable lifting and lowering of the drill 33, thereby enabling stable drilling of the valve plate, the drilling mechanism 3 includes a cylinder 31 mounted on the top of the top frame 2 and a support rod 34 mounted on the upper inner side of the top frame 2. A connecting plate 32 is mounted on the bottom end of the cylinder 31, and the drill 33 is mounted on the bottom end of the connecting plate 32. A buffer spring 35 is connected to the lower outer wall of the support rod 34. Through the operation of the cylinder 31, with the support of the support rod 34, the height of the drill 33 can be more stably adjusted, thereby improving the stability of drilling. A cleaning assembly 301 for removing debris is provided on the base 1.

[0030] During the drilling process of the valve plate, a certain amount of debris will be generated. In order to clean up the debris in a timely manner, the cleaning assembly 301 includes a dust collector head 36 fixedly mounted inside the top frame 2 and a side groove 37 provided at the side end of the base 1. A slider 38 is slidably connected to the side groove 37. A pull rod 39 is fixedly mounted on the side end of the slider 38. A scraper rod 310 is fixedly mounted on the top end of the slider 38 and abuts against the inner bottom end of the base 1. By connecting the extraction end of the vacuum cleaner to the dust collector head 36, some of the debris can be absorbed. The pull rod 39 pulls the slider 38 to slide inside the side groove 37, causing the scraper rod 310 to scrape off the debris that falls from the inner bottom end of the base 1.

[0031] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.
