Technical Field

The utility model relates to the technical field of winding mandrels, in particular to an expansion mandrel for a capillary winding copper pipe.

Background

In the copper pipe course of working, the copper pipe is behind set rubbish or internal thread pipe forming unit, will loose set copper pipe winding into circle form coil pipe through the coiler, the convenience is carried in the supply of coil pipe mode, the user uses swiftly, but among the prior art, the copper pipe of winding completion is along with the increase of the number of piles, because the pressure on each layer copper pipe more layer leads to the tight hoop of copper pipe coil pipe at the winding dabber, need apply very big axial force and just can follow the dabber and take off, and destroy the angle of detaining mutually between silk and the silk easily, and simultaneously, need to change different dabbers for the copper pipe coil pipe of preparation different diameters, lead to the cost-push with this.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides the capillary wound copper pipe expansion shaft core, which can effectively solve the problems in the background art by winding the copper pipe through the winding shell with adjustable diameter.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a capillary winding copper pipe inflation axle core, is including winding shell, axle sleeve, driving plate, rotating pin and bearing, and the winding shell is the arc structure, and three group's winding shells constitute a circular structure, and four earboards of every group winding shell inner wall are connected with the one end of four group's driving plates through the rotating pin, and the other end of four group's driving plates passes through rotating pin and axle sleeve connection, and the axle sleeve is located same straight line with the axle center of three group's winding shells, axle sleeve front end port and bearing fixed connection.

Further, the shaft sleeve is of a cylindrical structure with a hollow middle part, and the height of the shaft sleeve is consistent with that of the winding shell.

Furthermore, pin holes corresponding to the rotating pins are uniformly formed in the connecting end of the transmission plate and the shaft sleeve.

Furthermore, the inner wall of the bearing is provided with a U-shaped clamping groove, and the bearing is connected with an external transmission device.

Compared with the prior art, the utility model has the beneficial effects that: the capillary wound copper pipe expansion shaft core drives the shaft sleeve to perform pushing and pulling actions through the external transmission device, three groups of super wound shells diffuse outwards in the process of pulling the shaft sleeve out, namely the circles formed by the three groups of wound shells gradually increase, when the transmission plate and the wound shells and the shaft sleeve form a vertical state, the circle formed by the three groups of wound shells is the largest, when winding is completed, the external transmission device pushes the shaft sleeve into the wound shells, the circles formed by the three groups of wound shells gradually decrease, and the circles decrease, and simultaneously, the wound shells and a copper pipe coil automatically separate from each other. Providing convenience for people.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a capillary winding copper pipe expansion shaft core comprises a winding shell 1, a shaft sleeve 2, transmission plates 3, rotation pins 4 and bearings 5, wherein the winding shell 1 is of an arc structure, three groups of winding shells 1 form a circular structure, four groups of lug plates on the inner wall of each group of winding shell 1 are connected with one ends of four groups of transmission plates 3 through the rotation pins 4, the other ends of the four groups of transmission plates 3 are connected with the shaft sleeve 2 through the rotation pins 4, the shaft sleeve 2 and the three groups of winding shells 1 are positioned on the same straight line, the front side port of the shaft sleeve 2 is fixedly connected with the bearings 5, the shaft sleeve 2 is of a cylindrical structure with a hollowed middle part, the height of the shaft sleeve 2 is consistent with the height of the winding shell 1, pin holes corresponding to the rotation pins 4 are uniformly arranged at one end, connected with the shaft sleeve 2, of the transmission plate 3 and the shaft sleeve 5 are in a vertical state, the diameter of a circle formed by the three groups of winding shells 1 is maximum, and the maximum diameter of the circles formed by the three groups of winding shells 1 can be adjusted through the pin holes at different positions, with this winding internal diameter of various copper pipe coils that is applicable to, increase application range, avoid the supporting use of work piece, reduce the processing cost, bearing 5 inner wall is equipped with U type draw-in groove, and bearing 5 is connected with outside transmission, it is the push-and-pull action to drive axle sleeve 2 through outside transmission 5, when axle sleeve 2 is pushed and pulled, be connected with the rotation of live pin 4 through driving plate 3, make the action of three group winding shells 1 shrink and diffusion, the copper pipe twines under the diffusion state, consequently, with three group winding shells 1 automatic breakouts under the shrink state, simultaneously in winding copper pipe, bearing 5 reduces the friction system of winding in-process, winding smoothness has been guaranteed in proper order, improve the winding speed.
