Abstract
The utility model relates to a wheel rim expansion machine, comprising expansion dies and a conical guide shaft. The wheel rim expansion machine is characterized in that a first upper die plate and a second upper die plate are arranged above the expansion dies; a lower die plate is arranged below the expansion dies; the guide shaft is fixed on the first upper die plate and extends downwards; through holes are arranged in the central parts of the second upper die plate and the lower die plate for the guide shaft to traverse; the expansion dies are composed of a plurality of expansion die blocks which are arranged in central symmetry along the circumference direction; the expansion dies are fixed on upper and lower guide blocks which are arranged between the second upper die plate and the lower die plate, and guide grooves are arranged on the upper and lower guide blocks; stoppers are arranged on the second upper die plate and the lower die plate; and pressure springs are arranged between the stoppers and the upper and lower guide blocks. The expansion die blocks of the utility model is arranged in the expansion machine in a split type. The expansion machine has a unique and reasonable structure so that production cost is greatly reduced, manufacture precision is greatly increased, assembling and debugging are simple and convenient, and production quality of wheel rims is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of wheel processing unit (plant), particularly a kind of wheel rim expanding machine.
Background technology
The expanding operation is the critical process during the wheel rim of inner tube-free wheel is produced, and the expanding machine is a crucial tooling device of finishing this procedure.The expanding machine of the wheel processing usefulness of using in the prior art all is a up-down structure, mould stroke up and down all selects for use circular cone to cooperate, to increase considerably processing cost under the prerequisite that machining accuracy need increase, and interchangeability is very poor, the workman is difficult to adjust to the right place when the debugging mould.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provide a kind of structure more reasonable, use the expanding of wheel rim efficiently machine easy to adjust.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of wheel rim expanding machine, comprises the expanding mould and the taper axis of guide, is characterized in: be provided with first cope match-plate pattern and second cope match-plate pattern above the expanding mould, be provided with lower bolster in the bottom of expanding mould; The described axis of guide is fixed on first cope match-plate pattern and downwards and extends, and is provided with the through hole that passes for the axis of guide at second cope match-plate pattern and lower bolster middle part; Described expanding mould by some along the circumferential direction the symmetrically arranged expanding module in center form, the expanding mould is fixed on up and down on the guide pad, guide pad is located between second cope match-plate pattern and the lower bolster up and down, is equipped with gathering sill on the guide pad up and down; Fixedly connected respectively pressing plate and the guide plate of being provided with on second cope match-plate pattern, lower bolster, pressing plate is located in the gathering sill; On second cope match-plate pattern, lower bolster, be provided with link stopper, block and be connected with stage clip up and down between the guide pad.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described wheel rim expanding machine is characterized in: be provided with the buffering elastomeric layer between first cope match-plate pattern and second cope match-plate pattern.
Compared with prior art, expanding module of the present utility model is selected split type being assemblied on the expanding machine for use, expanding machine structure uniqueness, rationally, production cost significantly reduces, and the accuracy of manufacture significantly improves, assembling and setting is simple and convenient, and big effect is provided in effective assurance performance of the wheel rim quality of production.
