The utility model is greater than cylinder desired size and cylinder shrinkage die for the size after the expansion of existing cylinder
Problem at high cost provides a kind of shrinkage die.
As shown in Figs 1-4, the utility model embodiment provides a kind of shrinkage die, including bottom end has semi-circular chamber
Upper mold 6, top there is the lower die 1 of semi-circular chamber and the guide post guide sleeve structure of the connection upper mold 6 and the lower die 1, it is described
Cylindrical type is collectively formed in the semi-circular chamber of the upper mold 6 and the semi-circular chamber of the lower die 1 when upper mold 6 and the fitting of the lower die 1
Cylinder 9 to be shunk is placed on the semi-circular intracavitary of the lower die 1 by chamber 8, pushes the upper mold 6,9 quilt of cylinder to be shunk
It is pressed into predetermined size.
Size of the shrinkage die of the utility model for after solving prior art middle cylinder body expanding is greater than desired size
Problem, the case where being greater than within desired size 2mm suitable for the size after cylinder expanding, compared with existing cylinder shrinkage die
Compared with the structure of the shrinkage die of the utility model is simple, at low cost.The shrinkage die of the utility model is in use, first
First, the upper mold 6 is mounted on hydraulic press, the upper mold 6 is lifted using hydraulic press, the cylinder 9 to be shunk is placed
In the semi-circular intracavitary of the lower die 1；Again, the upper mold 6 is pressed downward using the hydraulic press, is depressed into the upper mold 6
The tip contact of bottom end and the lower die 1, at this point, the cylinder to be shunk 9 is located in cylindrical type chamber 8, the cylinder 9 to be shunk
It is pressed into predetermined size；Finally, being risen the upper mold 6 using the hydraulic press, will be depressed into described in predetermined size
Cylinder 9 to be shunk takes out.The top end face of the upper mold 6 of the utility model and the bottom face of the lower die 1 are plane, are convenient for
The upper mold 6 and the lower die 1 are connect with other mechanisms, after the upper mold 6 and the molding of the lower die 1, the top of the upper mold 6
