Description
Technical Field
The utility model relates to an expanding machine.
Background
After the existing round pipe fitting is processed, the roundness of the pipe body is often insufficient, and the roundness of the pipe body needs to meet the requirement through a subsequent process. The conventional mode is that rounding is manually carried out, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an expanding machine aims at solving above-mentioned problem through this expanding machine.
In order to achieve the purpose, the technical scheme of the utility model is to design an expanding machine, which comprises a frame, a hydraulic oil cylinder, a self-lubricating bearing, a round nut, a cone core, an outer cone sleeve, an expanding die, a platform, a stand column, a supporting seat plate and a reset spring;
the platform is arranged on the upper part of the frame; the cylinder body of the hydraulic oil cylinder is arranged on the lower surface of the platform; the supporting seat plate is fixed on the upper surface of the platform through a plurality of stand columns; holes are formed in the centers of the platform and the supporting seat plate, a self-lubricating bearing is arranged in the center hole of the platform, and a piston rod of the hydraulic oil cylinder penetrates through the self-lubricating bearing; the top of a piston rod of the hydraulic oil cylinder is connected with a conical core through a round nut, the conical core is of a cylindrical structure with a wide upper part and a narrow lower part, and the conical core penetrates through a hole in the center of the support seat plate; the outer taper sleeve is of a cylindrical sleeve structure formed by a plurality of arc-shaped thin sheets in a surrounding mode, the outer taper sleeve is sleeved outside the taper core, the inner wall of the outer taper sleeve is formed into an inclined plane and attached to the outer surface of the outer taper sleeve, the outer taper sleeve is located on the upper surface of the supporting seat plate, an annular groove is formed in the edge of the bottom of the outer taper sleeve, and the return spring is annular and embedded into the annular groove in the bottom of the outer taper sleeve; the bulging die comprises a plurality of arc-shaped pieces, each arc-shaped piece is attached to the outer portion of each arc-shaped piece of the outer taper sleeve one by one, and the bottom of each arc-shaped piece is connected with each arc-shaped piece of the outer taper sleeve through a pin.
Preferably, the outer taper sleeve is a cylindrical sleeve structure formed by six arc-shaped thin sheets in a surrounding mode; the expansion die is composed of six arc-shaped pieces.
Preferably, the support seat plate is fixed on the upper surface of the platform through four upright posts.
During the use, will need round circular pipe fitting cover outside the bulging die, then utilize hydraulic cylinder to make the awl core move down, the in-process that moves down is because wide down is narrow on the awl core to make outer taper sleeve constantly outwards expand, namely make the bulging die outwards expand. The expansion die expands the round pipe fitting which is originally not round enough to expand the round pipe fitting from the inside, and finally the round pipe fitting with enough round degree is obtained. And taking down the round pipe fitting, enabling the outer taper sleeve and the expansion die to return to the original state by the contraction of the return spring, stopping the movement of the hydraulic oil cylinder, and returning the taper core to the initial position in the reduction process of the outer taper sleeve.
The utility model has the advantages and the beneficial effects that: the utility model relates to a bulging machine can realize the diameter size school circle process of circular pipe fitting, to the higher condition of external diameter size required precision, can improve product diameter precision, and is easy and simple to handle, and the whole circle is efficient.
