Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing tools, in particular to a novel bellows beater. Background Art

[0002] At present, the installation construction site of corrugated pipes often needs to use corrugated pipes of different lengths according to actual needs. Therefore, the corrugated pipes need to be cut and then flattened by a corrugated pipe beater to facilitate the connection between the corrugated pipes and pipe fittings.

[0003] However, the bellows wave beater widely used in the industry generally fixes the pivotal structure between the mother and child shells by welding. In an environment where it is frequently struck, the welding point is prone to vibration and falling off. In addition, the connection of the pressure rod is a simple sliding connection. During the handling process, the pressure rod is easy to slide out of the mother shell and fall off. Utility Model Content

[0004] In order to solve the above defects, the utility model provides a novel bellows beater, which solves the problems of structural stability and the pressure rod being easily dropped and lost.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A new type of bellows beater, including a mother shell, a child shell, a pressure rod and a limit ring, the mother shell and the child shell are pivotally fixed by a positioning pin; the mother shell includes a cylindrical shell and an upper die head arranged in a semicircular shape, the child shell includes a semicircular lower die head, the inner walls of the upper die head and the lower die head are respectively provided with semicircular clamping rings, and the upper die head and the lower die head can be firmly buckled; an installation channel extending along the axis of the mother shell is provided inside the shell, and a limit groove for placing the limit ring is provided on the inner wall of the installation channel, an annular slide groove is provided in the middle of the pressure rod, and the annular slide groove is slidably connected to the limit ring, a fixing protrusion is provided on the bottom end face of the pressure rod, and a striking area is provided on the top.

[0007] Furthermore, the upper die head also includes an upper sleeve and a lower sleeve formed in one piece, and the lower sleeve is provided with a through hole.

[0008] Furthermore, the lower die head also includes a middle shaft sleeve arranged on one side, and the upper shaft sleeve, the middle shaft sleeve and the lower shaft sleeve are connected through the positioning pin to form a pivot structure.

[0009] Furthermore, the limiting ring is a C-shaped retaining spring with a square cross-section, which is used to limit the axial movement of the pressure rod within the range of the annular groove.

[0010] Furthermore, the cross section of the clamping ring is triangular, with one side being an arc.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] 1. By setting an integrally formed pivot structure, the mother shell and the child shell are connected into a movable and rotatable structure, thereby improving the stability and firmness of the wave beater structure.

[0013] 2. By setting the limit ring, the limit groove and the annular slide, the pressure rod can be restricted from sliding inside the mother shell and confined to the annular slide area, thereby ensuring a sufficient striking distance while preventing the pressure rod from falling and being lost.

[0024] refer to Figure 1 、 Figure 2 and Figure 3 The upper die head also includes an upper sleeve and a lower sleeve formed in one piece, and the lower sleeve is provided with a through hole.

[0025] By adopting the above technical solution, an upper sleeve 121 and a lower sleeve 122 are provided and a through hole 1221 is provided on the lower sleeve. The positioning pin 5 is inserted through the through hole 1221 and then passes through the lower sleeve 122 and is further inserted into the upper sleeve 121 to form a pivot connection.

[0026] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The lower die head also includes a middle shaft sleeve arranged on one side, and the upper shaft sleeve, the middle shaft sleeve and the lower shaft sleeve are connected through the positioning pin to form a pivot structure.

[0027] By adopting the above technical solution, a middle shaft sleeve 211 is provided to cooperate with the upper shaft sleeve 121 and the lower shaft sleeve 122 , and the positioning pin 5 is used to penetrate and connect them to form a pivot structure.

[0028] refer to Figure 2 and Figure 3 The limiting ring is a C-shaped retaining spring with a square cross-section, which is used to limit the axial movement of the pressure rod within the range of the annular groove.

[0029] By adopting the above technical solution, by setting the limit ring 4 as a C-shaped retaining spring, the limit ring 4 can be deformed and enter the installation channel 13 of the mother shell 1 along the annular groove 32 of the pressure rod 3. After the limit ring 4 is restored, it is stuck in the limit groove 14. In this way, the pressure rod 3 can only be limited to the height of the annular groove 32 for axial movement, but it also ensures that the displacement distance of the pressure rod 3 can achieve a good flat-end effect, which solves the problem of the pressure rod of the ordinary wave beater easily slipping out of the mother shell and falling and being lost.
