Abstract
The utility model discloses a kind of copper pipe rolling core bar and the device that is connected of plug, including core bar and plug, connecting rod is provided between the core bar and plug, connecting rod one end is inserted in the screwed hole of core bar by the first screw rod and is connected with core bar, plug is inserted by the second screw rod in the screwed hole of the connecting rod other end to be connected with connecting rod, and one group is offered in connecting rod and is used for the neck that ozzle pincers are caught in.The utility model easily quickly can unload plug and at all lossless to core bar, it is simple in construction, change it is convenient, avoid because damage core bar and caused by waste.
Description
Technical field
The utility model is related to a kind of Local Members of copper pipe rolling equipment, more particularly to a kind of copper pipe rolling core bar with
The device that is connected of plug.
Background technology
In rolling, copper pipe will be placed on core bar and plug copper pipe, 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, single-handedly directly unload highly difficult, will now used ozzle pincers and 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
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of not damage core bar, be conveniently replaceable plug
The device that is connected of copper pipe rolling core bar and plug.
The utility model is achieved by the following technical solution：A kind of connection of copper pipe rolling core bar and plug is consolidated
Determine device, including core bar and plug, it is characterized in that：Connecting rod is provided between the core bar and plug, connecting rod one end passes through
It is connected in the screwed hole of one screw rod insertion core bar with core bar, plug is inserted by the second screw rod in the screwed hole of the connecting rod other end
It is connected with connecting rod, one group is offered in connecting rod and is used for the neck that ozzle pincers are caught in.The connecting rod is along its length
Passage is provided with center, passage ending vertical connecting rod outer wall extends.
The beneficial effects of the utility model are：Easily quickly it can unload plug and at all lossless to core bar, simple in construction,
It is convenient to change, avoid because damage core bar and caused by waste.
Brief description of the drawings
Accompanying drawing 1 shows the structure of the device that is connected of a kind of copper pipe rolling core bar of the utility model and plug, under
Face is further described with reference to accompanying drawing 1.
Embodiment
Accompanying drawing 1 shows a kind of structure of the device that is connected of copper pipe rolling core bar and plug of the present utility model,
Including core bar 1 and plug 2, connecting rod 3 is provided between core bar 1 and plug 2, core bar is inserted in the one end of connecting rod 3 by the first screw rod 4
Is connected in 1 screwed hole with core bar 1, plug 2 pass through in the screwed hole of the second screw rod 5 insertion other end of connecting rod 3 with connecting rod 3
It is connected, one group is offered in connecting rod 3 and is used for the neck 6 that ozzle pincers are caught in.Connecting rod 3 is provided with center along its length
Passage 7, the outer wall of 7 ending vertical connecting rod of passage 3 extend.
During operation, in the neck 6 with ozzle pincers Snap joint bar 3, connecting rod 3 is fixed, turns plug 2, you can by core
Rod 2 unloads 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,
Installed by the way that the second screw rod 5 to be screwed into change new plug 2 in the screwed hole of connecting rod 3.
Claims (2)
