Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings:

referring to fig. 1, the pneumatic brake bead structure of the present invention includes an upper die and a lower die, wherein the upper die includes an upper die base 1 and a punch 2 disposed below the upper die base, the lower die includes a lower die base 3 and a lower die plate 4 disposed on the lower die base 3 and engaged with the punch 2,

the two sides of the lower template are symmetrically provided with a pneumatic drawing structure 5 and a pneumatic drawing structure 6,

the pneumatic drawing structure 5 comprises an air cylinder 7, a connecting arm 8, a drawing plate 9 and a drawing plate mounting column 10, wherein the drawing plate mounting column 10 is fixed on the lower die holder 3, a sliding column 11 is arranged on the drawing plate mounting column 10, the sliding column 11 is arranged in an upper sliding groove 12 and a lower sliding groove 12 of the drawing plate 9 to enable the drawing plate 9 to slide up and down along the drawing plate mounting column 10, one end of the drawing plate 9 is arranged in a trapezoidal groove 13 at one end of the connecting arm and matched with the trapezoidal groove 13, the opening of the trapezoidal groove 13 is large, the bottom of the groove is small, and the other end of the connecting arm 8 is connected with a piston rod of the air cylinder 7; the drawing plate 9 comprises an upper drawing plate 14 and a lower drawing plate 15, four drawing beads 16 are arranged on the inner wall surface of the other end of the lower drawing plate 15, drawing bead grooves 17 matched with the drawing beads 16 are arranged on the inner wall surface of the other end of the upper drawing plate 15, a left spring 18 is arranged between one end of the upper drawing plate 14 and one end of the lower drawing plate 15, and a right spring 19 is arranged between the other end of the upper drawing plate 14 and the other end of the lower drawing plate 15.

When the material drawing machine works, referring to fig. 1 and fig. 2, firstly, a material is placed on a lower die plate, an upper die moves downwards, a punch is matched with the lower die plate to process the material, meanwhile, the air cylinder pushes the connecting arm to move horizontally inwards, the trapezoidal groove at the right end of the connecting arm simultaneously extrudes the upper drawing plate and the lower drawing plate to move downwards and upwards respectively, so that a drawing rib groove of the upper drawing plate and a drawing rib of the lower drawing plate draw the material, the left spring and the right spring are compressed simultaneously, the drawing strength is reduced, the labor intensity of workers is reduced, and the production efficiency is greatly improved.
