Abstract
The utility model discloses a novel one-way mandrel, and relates to a mechanical tool. The novel one-way mandrel comprises a one-way mandrel rod (1), a spring (2), a guide pin (3), a fixing pin (4), a hollow ball (5) and an oscillating rod (6), wherein the spring (2) is arranged in the one-way mandrel rod (1); the guide pin (3) is arranged at the right end of the spring (2); the oscillating rod (6) is fixedly arranged on the one-way mandrel (1) through the fixing pin (4), and is arranged at the right end of the guide pin (3); and the hollow ball (5) is fixedly arranged on the oscillating rod (6). The service life of the one-way mandrel is greatly prolonged; and the ball has a smooth surface, and is high in smooth finish, high in abrasion resistance and low in frictional force, and is difficultly adhered to a material, so that the pipe bending quality is more stable, and after a pipe is bent, a strain rate in a pipe orifice is low.
Description
Technical field:
The utility model relates to a kind of machine tool, is specifically related to a kind of novel bending machine that is used for the air conditioner two-unit industry, the unidirectional mandrel above the equipment such as U bender.
Background technology:
In machinery industry, unidirectional mandrel is mainly used in Copper pipe bender, above the U bender equipment, the swing ball of at present domestic unidirectional mandrel all is whole, and swing ball and mostly be the techniques such as general steel quenching surface of polished plating Chrome or the rear polishing plating of mould steel quenching Chrome, but the groundwork face of mandrel ball is that a frictional force is larger, and friction is local very frequently, just there is a course of work several seconds, so after a period of time, wearing and tearing, plucking will appear in the ball surface, ball fineness reduces, size decreases, the phenomenons such as the sticking copper in ball surface are scrapped the individual event mandrel.
The utility model content:
The purpose of this utility model provides a kind of novel unidirectional mandrel, and it has prolonged the service life of individual event mandrel, ball smooth surface, highly polished greatly, wearability is strong, and frictional force is little, is difficult for sizing, make bending quality more stable, behind the bend pipe, be difficult in the pore pulling.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises unidirectional mandrel rod 1, spring 2, pilot pin 3, steady pin 4, georama 5 and swing arm 6; Spring 2 is arranged on unidirectional mandrel rod 1 inside, and pilot pin 3 is arranged on the right-hand member of spring 2, and swing arm 6 is fixed on the unidirectional mandrel 1 by steady pin 4, and swing arm 6 is arranged on the right-hand member of pilot pin 3, and georama 5 is fixed on the swing arm 6.
Described georama 5 adopts Hardmetal materials to make.
The ball outside dimension of described georama 5 is Φ 4mm-Φ 30mm.
The internal diameter size of described georama 5 is Φ 2mm-Φ 15mm.
Described georama 5 is bonded together by foundry work glue and swing arm 6, rivets after the foundry work gelling is solid again, grinds at last moulding.
The utlity model has following beneficial effect: it has prolonged the service life of individual event mandrel greatly, ball smooth surface, highly polished, and wearability is strong, and frictional force is little, is difficult for sizing, makes bending quality more stable, behind the bend pipe, is difficult in the pore pulling.
Description of drawings:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the constitutional diagram of the utility model hollow core ball and swing arm,
Fig. 3 is the structural representation of swing arm in the utility model,
Fig. 4 is the structural representation of the utility model hollow core ball.
The specific embodiment:
Referring to Fig. 1-4, this specific embodiment by the following technical solutions: it comprises unidirectional mandrel rod 1, spring 2, pilot pin 3, steady pin 4, georama 5 and swing arm 6; Spring 2 is arranged on unidirectional mandrel rod 1 inside, and pilot pin 3 is arranged on the right-hand member of spring 2, and swing arm 6 is fixed on the unidirectional mandrel 1 by steady pin 4, and swing arm 6 is arranged on the right-hand member of pilot pin 3, and georama 5 is fixed on the swing arm 6.
Described georama 5 adopts Hardmetal materials to make.
The ball outside dimension of described georama 5 is Φ 4mm-Φ 30mm.
The internal diameter size of described georama 5 is Φ 2mm-Φ 15mm.
Described georama 5 is bonded together by foundry work glue and swing arm 6, rivets after the foundry work gelling is solid again, grinds at last moulding.
The swing ball of the unidirectional mandrel of this specific embodiment is set to two parts, both carbide alloy ball part and swing arm part, carbide alloy is difficult-to-machine material, so simple shape is processed well, swing arm is general material, but the structure of processed complex, the sticking riveting of two accessories become the rounding ball polishing etc. of regrinding after the integral body.This structure has prolonged the service life of individual event mandrel greatly, is more than 20 times of present traditional individual event mandrel service life, ball smooth surface, highly polished, wearability is strong, and frictional force is little, is difficult for sizing, make bending quality more stable, behind the bend pipe, be difficult in the pore pulling.
