Description

Diameter reducing device for rubber bushing Technical Field The utility model relates to the technical field of bushing diameter reduction, in particular to a rubber bushing diameter reduction device. Background The inner sleeve and the outer sleeve of the rubber bushing are adhered to the bushing structure of the rubber, after vulcanization molding, the rubber is cooled and contracted, the rubber and the inner sleeve are firmly adhered, no contraction space exists between the rubber, and tensile stress exists between molecules. Through retrieving, in the application of patent application number CN205889874U, disclose a rubber bushing diameter reducing device, including lower mould, last mould, lamella mould, the lower mould includes central point position locating pin and radial distribution has T type groove, go up the inside cavity toper that sets up of mould, lamella mould is including the lamella die body, the slider of dividing into a plurality of lamella, slider slidable sets up in T type inslot to fix on the lamella die body, the lamella mould is exerted down pressure on last mould and is closed the back, and the center forms the cavity, and sets up into the shape of rubber bushing, radially compresses the rubber bushing, thereby can process unconventional rubber bushing. But because the setting of last mould and lamella mould, the cavity forms the shape of rubber bush, then compresses rubber bush, and rubber bush's internal diameter does not have the holding power, and compressive force is too big, causes the deformation of rubber bush easily, leads to the effect of reducing poor, simultaneously because the setting of lower mould and last mould, places rubber bush on the lower mould and reduces the footpath, after the reducing is accomplished, because rubber bush is in the cavity, leads to inconvenient taking out the bush, inconvenient use. Therefore, we propose a rubber bushing diameter reducing device. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the diameter reducing device for the rubber bushing, and solves the problems that the diameter reducing effect of the conventional device is poor and the rubber bushing is inconvenient to take out.
