DETAILED DESCRIPTION

[0020] The utility model is further described in detail below through the drawings and embodiments.

[0021] like Figure 1-3As shown: a clamping cylinder stamping die mechanism of a brake air chamber, the outer edge convex position of the upper side of the clamping cylinder 1 is circumferentially stamped at intervals to form an inwardly convex buckle groove 2, the mechanism includes a cylinder seat 3, the cylinder seat 3 is provided with a receiving groove 4 that matches the size of the clamping cylinder 1, and the clamping cylinder 1 can be placed in the cylinder seat 3 in a slightly fitted manner. An annular notch 5 is circumferentially opened on the upper side of the cylinder seat 3, and through grooves 6 that match the buckle groove 2 required to be stamped on the clamping cylinder 1 are spaced apart inside the annular notch 5.

[0022] A punching block 7 is respectively arranged in each through groove 6 . The punching block 7 is radially slidably connected to the inner wall of the bottom of the annular notch 5 . An extrusion piece is arranged on the outer side of the punching block 7 to give the punching block 7 an inward force to punch the cylinder seat 3 .

[0023] like Figure 4 As shown: the extrusion component in this embodiment includes a connecting block 8 with a cross section, a slider 9 is provided at the bottom of the connecting block 8, the slider 9 is slidably connected to the bottom inner wall of the annular notch 5 through a preset slide groove, a support block 10 is connected to the inner wall of the annular notch 5, and the support block 10 and the slider 9 are connected by a spring 11, so that after the stamping force is removed, the stamping block 7 can be driven by the spring 11 to return to the through groove 6.

[0024] The extrusion piece also includes an extrusion block 12, on which a section adapted to the connection block 8 is provided. When the extrusion block 12 abuts against the connection block 8, the stamping block 7 is driven to move inward by extrusion. Due to the arrangement of the slider 9, the connection block 8 drives the stamping block 7 to always maintain radial movement. In this embodiment, only two extrusion blocks 12 are arranged. If there are too many, a greater driving force is required to drive the stamping blocks 7 to move simultaneously, which makes it difficult to stamp and form. Secondly, the process of the extrusion block 12 squeezing the connection block 8 needs to be relatively short, otherwise it is difficult to stamp and form.

[0025] The extrusion block 12 is rotated by the driving structure to sequentially extrude the corresponding spaced connection blocks 8. The outer edge of the bottom of the annular notch 5 is penetrated by two arc-shaped notches 13 (according to the positions of the extrusion block 12 and the connection block 8, the extrusion block 12 is provided with two, that is, the overall circumferential stamping of the buckle cylinder 1 can be completed by rotating half a circle), and the bottom of the extrusion block 12 is connected to the annular rotating block 14, and the bottom of the annular rotating block 14 is connected to the driving structure by means of the space of the arc-shaped notch 13, and rotates under the drive thereof.

A gear groove is provided on the inner edge of the gear seat 16, and the gear seat 16 is driven to rotate by a gear 17. The gear 17 is provided with a plurality of gears which are respectively meshed with the gear 17 seat. The gear 17 is driven to rotate by a gear 2 18 which is meshed in the middle, and the gear 2 18 is driven by a motor.
