DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0019] like Figure 2 As shown, this embodiment provides a flame tube cap forming tool, including a supporting platform 1, a stamping ring 2, and a stamping column 3.

[0020] Specifically, Figure 2 and Figure 3 As shown, the supporting platform 1 is in the shape of a cube, and a cylindrical containing chamber 11 is vertically opened in the middle of its upper surface, and a first concave arc surface 12 is opened at the top edge of the containing chamber 11. More specifically, the cross-section of the first concave arc surface 12 is in the shape of a quarter of a circle, and the tangents of its two edges are respectively perpendicular and parallel to the upper surface of the supporting platform 1.

[0021] Specifically, Figure 2 and Figure 3As shown, the stamping ring 2 is coaxially arranged directly above the accommodating chamber 11, and the stamping ring 2 is arranged to move vertically, and a convex arc surface 13 is provided at the bottom thereof. More specifically, the cross-section of the convex arc surface 13 is semicircular, and the tangents of its two edges coincide with the outer ring surface and the inner ring surface of the stamping ring 2 respectively; the first concave arc surface 12 is used to cooperate with the outer side of the convex arc surface 13, and the outer side refers to the quarter arc surface of the convex arc surface 13 close to the outer ring surface of the stamping ring 2.

[0022] Specifically, Figure 2 and Figure 3 As shown, the stamping column 3 is vertically movable and arranged on the central axis of the accommodating bin 11, the edge of the stamping column 3 is slidably matched with the surface of the accommodating bin 11, and a second concave arc surface 31 is provided on the top edge of the stamping column 3. More specifically, the cross-section of the second concave arc surface 31 is in the shape of a quarter arc, and the tangents of its two edges are respectively parallel and perpendicular to and parallel to the upper surface of the stamping column 3; the second concave arc surface 31 is used to cooperate with the inner side of the convex arc surface 13, and the inner side refers to the quarter arc surface of the convex arc surface 13 close to the inner ring surface of the stamping ring 2.

[0023] During operation, the height of the stamping column 3 is adjusted so that the upper surface of the stamping column 3 is coplanar with the upper surface of the supporting platform 1. At this time, the first concave arc surface 12 cooperates with the second concave arc surface 31 to form a concave arc groove with a semicircular cross-section; the raw material plate of the flame tube cap is placed on the upper surface of the supporting platform 1 so that it is coaxial with the containing bin 1, and the stamping ring 2 is moved downward so that the convex arc surface 13 contacts the raw material plate and presses it into the concave arc groove, so that the raw material plate is formed in the concave arc groove; the stamping ring 2 is moved upward so that the convex arc surface 13 leaves the raw material plate, and at this time, the stamping column 3 is moved upward, and the stamping column 3 drives the formed flame tube cap to leave the first concave arc surface 12. At this time, the flame tube cap can be taken out from the forming tooling more conveniently.

[0024] Preferably, Figure 2 As shown, an electric screw 14 is vertically provided on the supporting platform 1. Specifically, in this example, two electric screws 14 are provided. The electric screws 14 are each equipped with a drive sleeve 15. A drive plate 16 is connected between the drive sleeve 15 and the stamping ring 2. The electric screw 14 is used to drive the drive sleeve 15 to move vertically, and then drive the stamping ring 2 to move vertically through the drive plate 16.

[0025] Preferably, Figure 3 As shown, a first cylinder 17 is vertically arranged in the accommodating bin 11 , and a driving shaft of the first cylinder 17 is connected to the stamping column 3 for driving the stamping column 3 to move vertically.

[0026] Preferably, Figure 2 and Figure 3As shown, a plurality of limit bars 18 are slidably provided on the carrier platform 1. Specifically, in this example, four limit bars 18 are arranged in a circular array along the central axis of the accommodating bin 11 on the carrier platform 1; second cylinders 19 are arranged radially along the accommodating bin 11 in a number matching the limit bars 18 on the carrier platform 1, and the driving axes of the second cylinders 19 are connected to the limit bars 18 one by one, and the limit bars 18 are perpendicular to the driving axes of the second cylinders 19. The limit bars 18 are used to push the raw material plate placed on the upper surface of the carrier platform 1 to a position coaxial with the accommodating bin 11, and to limit the raw material plate.

[0027] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
