Abstract
It is connected device the invention discloses one kind, including core bar and plug, connecting rod is provided between the core bar and plug, connecting rod one end is inserted by the first screw rod to be connected in the screwed hole of core bar with core bar, plug is inserted by the second screw rod to be connected in the screwed hole of the connecting rod other end with connecting rod, and one group is offered in connecting rod is used for the neck that ozzle pincers are caught in.The present invention easily quickly can unload plug and at all lossless to core bar, simple in construction, change convenient, it is to avoid because damage core bar and caused by waste.
Description
Technical field
The present invention relates to a kind of Local Members of rolling equipment, more particularly to one kind is connected device.
Background technology
Copper pipe is in rolling, and copper pipe will be placed on core bar and plug, and plug can control copper pipe inner space, prevent copper pipe from rolling
To one piece, to ensure copper pipe inwall quality and size it is necessary to regularly replacing plug.However, change when it is necessary to plug from
Unloaded on core bar, it is free-hand directly to unload highly difficult, it will now use ozzle pincers to unload, core bar will be blocked when being unloaded with ozzle pincers,
But to ensure that copper pipe is not oxidized in the operation of rolling, open larger hole inside core bar again, cause core bar wall thickness smaller,
Fluting is caught in ozzle pincers and just easily damages core bar on core bar.
The content of the invention
There is provided a kind of copper pipe for not damaging core bar, being conveniently replaceable plug in order to make up the deficiencies in the prior art by the present invention
The device that is connected of rolling core bar and plug.
The present invention is achieved through the following technical solutions：One kind is connected device, including core bar and plug, and it is special
Levying is：Between the core bar and plug be provided with connecting rod, connecting rod one end pass through the first screw rod insert core bar screwed hole in
Core bar is connected, and plug is inserted by the second screw rod to be connected in the screwed hole of the connecting rod other end with connecting rod, is opened in connecting rod
It is used for the neck that ozzle pincers are caught in provided with one group.The center of the connecting rod along its length is provided with passage, passage end
End vertical connecting outer wall extends.
The beneficial effects of the invention are as follows：Easily quickly it can unload plug and, simple in construction, replacing at all lossless to core bar
It is convenient, it is to avoid because damage core bar and caused by waste.
Brief description of the drawings
Accompanying drawing 1 shows a kind of structure for the device that is connected of the present invention, 1 is further described below in conjunction with the accompanying drawings.
Embodiment
Accompanying drawing 1 shows a kind of structure of device that is connected of the present invention, including core bar 1 and plug 2, core bar 1 and core
Connecting rod 3 is provided between rod 2, the one end of connecting rod 3 is inserted by the first screw rod 4 to be connected in the screwed hole of core bar 1 with core bar 1, core
Rod 2 is inserted by the second screw rod 5 to be connected in the screwed hole of the other end of connecting rod 3 with connecting rod 3, and one is offered in connecting rod 3
Group is used for ozzle and clamps the neck 6 being caught in.The center of connecting rod 3 along its length is provided with passage 7, the ending vertical of passage 7
The outer wall of connecting rod 3 extends.
During operation, in the neck 6 that Snap joint bar 3 is clamped with ozzle, connecting rod 3 is fixed, plug 2 is turned, you can by core
Rod 2 is unloaded from connecting rod 3, it is therefore prevented that ozzle pincers are caught in core bar 1 and damage core bar 1.It is straight needed for passage 7 in connecting rod 3
Therefore footpath will not damage connecting rod 3 with regard to very little, ozzle pincers, then continue to be caught in the fixed connecting rod 3 of neck 6 with ozzle pincers,
New plug 2 is changed and installed by the way that the second screw rod 5 is screwed into the screwed hole of connecting rod 3.
Claims (2)
