Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an aluminum alloy bumper beam press-fitting sleeve device in the embodiment comprises a base 10 and a press-fitting die positioned on the base 10, wherein the press-fitting die consists of a power cylinder 1, a connecting rod 2, a guide post 3, an upper conical thimble 4, a material returning spring 5, a material returning plate 6, a material clamping cylinder 7, a lower conical thimble 8 and a bottom thimble 9; wherein, the power cylinder 1 is fixed above the supporting seat 11, the bottom of the supporting seat 11 is fixed on the base 10 through bolts; the telescopic end of the power cylinder 1 passes through the supporting seat 11 and is connected with the material returning plate 6 through the connecting rod 2; a guide post 3 is arranged between the lower part of the supporting seat 11 and the material returning plate 6; the upper conical thimble 4 and the material returning spring 5 are positioned on the material returning plate 6, the material returning spring 5 is used for providing power for returning materials after material returning is completed, the material returning plate 6 and the material returning spring 5 are matched to push away pressed materials from the upper conical thimble 4, a lower conical thimble 8 is arranged below the material returning plate 6, the lower conical thimble 8 is positioned at the bottom of the supporting seat 11, a bottom thimble 9 is arranged on the periphery of the lower conical thimble 8, the bottom thimble 9 is of three convex point structures, 120 DEG is formed between the three convex points and used for fixing the port at the lower end of the sleeve.

In the above embodiment, the lower conical thimble 8 corresponds to the position of the upper conical thimble 4 and is located on the same axis, the upper conical thimble 4 is used for expanding the port at the upper end of the sleeve, so that the sleeve and the beam form interference fit, and the lower conical thimble 8 is used for fixing the lower end position of the sleeve and assisting in fixing the beam.
