[0021] The present invention will be described in detail below with reference to specific embodiments.

[0022] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1 and Figure 2 As shown, a tooling for processing PVF filter elements includes a base plate 10, a cylinder 20, and two arc-shaped clamping plates 30.

[0025] The base plate 10 is a square base plate 10 or a circular base plate 10. A cylinder 20 is vertically provided on the base plate 10. A first cutting notch 21 is provided on one side of the cylinder 20. Below the first cutting notch 21, a material drop groove 11 is provided on the base plate 10. One end of the material drop groove 11 passes through one side of the base plate 10.

[0026] Two arc-shaped clamping plates 30 are vertically mounted on the base plate 10 and spaced apart on both sides of the half-circumference of the cylinder 20. A second cutting notch 31 is provided between the two arc-shaped clamping plates 30 above the material drop chute 11.

[0027] In practice, the PVF hollow tube is fitted onto the outer circumference of the cylinder 20, with part of it located between the two arc-shaped clamping plates 30 and the half-circumference of the cylinder 20. The operator holds a knife and cuts the PVF hollow tube along the inner walls of both sides of the notch to cut the PVF hollow tube into a C-shaped PVF filter element. The cut and separated waste material falls into the discharge trough 11, which is convenient for removing the waste material. The operation is quick and convenient, and there is no need to compare with the scale on the ruler to ensure that the size of each cut C-shaped tube notch is consistent.

[0028] Among them, the base plate 10, the material drop trough 11, the cylinder 20, the first cutting notch 21, the two arc-shaped clamping plates 30 and the second cutting notch 31 are integrated into one structure. They are all formed by processing block waste of PVF, realizing waste utilization and effectively reducing the production cost of the processing tool.

[0029] In this embodiment, the inner walls of the first cutting notch 21 and the second cutting notch 31 are provided with removable patches 40, which can be used to adjust the size of the notch so as to adapt to notch cutting of different sizes.

[0030] In this embodiment, the width of the first cutting notch 21 is greater than, less than or equal to the width of the second cutting notch 31, and the widths of the first cutting notch 21 and the second cutting notch 31 can be processed according to different size requirements.

[0031] In this embodiment, a pad 12 is provided on the upper surface of the base plate 10. The pad 12 is arranged opposite to the material discharge chute 11, and one end of the pad 12 is arranged perpendicular to the outer circumferential surface of the cylinder 20.

[0032] In practice, the upper surface of the pad 12 is higher than the upper surface of the base plate 10. The PVF hollow tube is fitted onto the outer circumference of the cylinder 20, and part of its lower surface is in contact with the pad 12, which raises the horizontal position of the PVF hollow tube on the base plate 10. After the notch is cut, it is convenient to pull the formed C-shaped tube upward from the raised gap at the bottom of the cylinder 20.

[0033] In this embodiment, a pressing block 13 is vertically provided on the pad 12, and a gap is provided between the pressing block 13 and the cylinder 20 to press the PVF hollow tube and prevent position displacement when cutting the notch, which would affect the cutting of the notch.

[0034] In this embodiment, the clamping block 13 is slidably disposed on the pad 12, thereby adjusting the clamping force on the PVF hollow tube.

[0035] The tooling for processing PVF filter elements provided by this utility model, compared with the prior art, involves fitting a hollow cylindrical tube of the PVF filter element onto a cylinder 20, with half of the hollow cylindrical tube located inside two arc-shaped clamping plates 30. The cylinder 20 and the two arc-shaped clamping plates 30 are respectively provided with a first cutting notch 21 and a second cutting notch 31 opening in the same direction. By limiting the first cutting notch 21 and the second cutting notch 31, it can effectively ensure that the size of each C-shaped tubular notch cut out is consistent. Manually holding the tool to cut the notch is quick and convenient, without the need to align with the scale on the ruler, effectively improving processing efficiency.

[0036] Where there is no conflict, the above embodiments and features can be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
