Abstract
The present invention provides a kind of pipeline orifice expander, including mouth expander frame, cylinder rack, oil cylinder, gland, slide block, top expander roll, guide post, back-moving spring, alignment pin, described mouth expander frame rear portion is provided with cylinder rack front portion and is provided with gland by bolt, described cylinder rack rear portion is provided with oil cylinder by bolt, described oil cylinder front end is provided with the top expander roll of cone, it is provided with slide block in described gland, described slide block totally six, it is arranged in a circular formation centered on the expander roll of described top, slip front highlights gland and forms cylinder, by alignment pin, guide post is installed on each described slide block, it is cased with back-moving spring on described guide post.The cylinder of described slip front can do stepped according to the use of different tube diameters expander.Using oil cylinder to top expander roll force, saving substantial amounts of manpower, improve efficiency, especially very convenient when bigbore pipeline enlarging, cylinder can do stepped, and same set of slide block can meet the pipeline enlarging processing of different-diameter.
Description
Technical field
The present invention relates to a kind of tube cutting device, particularly relate to a kind of pipeline orifice expander.
Background technology
Often having pipe and pipe or pipe and elbow welding at refrigeration industry, now welding is required to insert weldering, it is necessary to one end tube head
Internal diameter expands to more than pipe outside dimension, two pipes could be plugged in together, then weld.Common mouth expander such as Chinese patent
A kind of pipeline orifice expander disclosed in CN202316817U, it is characterised in that: include bolt (1), locking cone block (2), expanded support
Chunk (3), packing ring (4), stop sleeve (5) and nut (6), wherein, locking cone block (2) axially offers center
Through hole, locking cone block (2) is inserted on bolt (1) towards screw cap end set with big diametral plane by central through hole；Expanded support chunk (3) by
Some pieces of identical little expanded support block (3-1) docking combine, and the central axial formation of expanded support chunk (3) one forming
The conical through-hole closing with locking cone block (2) matching form, expanded support chunk (3) is socketed in locking cone block (2) by conical through-hole
Outside；Packing ring (4) is sheathed on the outside bolt (1) of locking cone block (2), and at packing ring (4) and expanded support chunk
(3) being provided with stop sleeve (5) between, stop sleeve (5) internal diameter is more than the hole diameter of the upper conical through hole of expanded support chunk (3)；
Nut (6) is twisted and is enclosed within the outside bolt (1) of packing ring (5), to some extent solves the demand of a part of expanding,
But this mouth expander uses manual torquing operations, wastes time and energy, and is not suitable for the expanding of larger caliber pipeline.
Content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of pipeline orifice expander, it is characterised in that: include mouth expander frame, oil
Cylinder frame, oil cylinder, gland, slide block, top expander roll, guide post, back-moving spring, alignment pin, described mouth expander frame rear portion is provided with oil
Cylinder frame front portion is provided with gland by bolt, and described cylinder rack rear portion is provided with oil cylinder by bolt, and described oil cylinder front end is provided with circle
The top expander roll of taper, is provided with slide block in described gland, described slide block totally six, is arranged in a circular formation centered on the expander roll of described top,
Slip front highlights gland and forms cylinder, and each described slide block is provided with guide post by alignment pin, and described guide post overlaps
There is back-moving spring.
Also by bolt, adjustment packing ring is installed in described cylinder rack.
The cylinder of described slip front can do stepped according to the use of different tube diameters expander.
The invention has the beneficial effects as follows: use oil cylinder to top expander roll force, it is to avoid conventional pipelines mouth expander needs manually to screw behaviour
Make, save substantial amounts of manpower, improve operating efficiency, especially very convenient when bigbore pipeline enlarging, and before slide block
The cylinder of end can do stepped according to the use of different tube diameters expander, and the pipeline enlarging that same set of slide block can meet different-diameter adds
Work.
Brief description
Fig. 1 is present configuration schematic diagram；
Fig. 2 is schematic cross-section of the present invention；
Fig. 3 is the present invention stepped slide block structure schematic diagram.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings:
In figure, the 1st, mouth expander frame；2nd, cylinder rack；3rd, oil cylinder；4th, gland；5th, slide block；6th, expander roll is pushed up；7th, guide post；
8th, back-moving spring；9th, alignment pin；10th, packing ring is adjusted；11st, cylinder.
As Figure 1-3, described mouth expander frame 1 rear portion is provided with cylinder rack 2 front portion and is provided with gland 4, described oil by bolt
Cylinder frame 2 rear portion is provided with oil cylinder 3 by bolt, and described oil cylinder 3 front end is provided with the top expander roll 6 of cone, sets in described gland 4
Having slide block 5, described slide block 5 totally six, being arranged in a circular formation centered on the expander roll 6 of described top, slide block 5 front end highlights gland 4
And form cylinder 11, each described slide block 5 is provided with guide post 7 by alignment pin 9, described guide post 7 is cased with reset
Spring 8.
Also by bolt, adjustment packing ring 10 is installed in described cylinder rack 2.
The cylinder 11 of described slide block 5 front end can do stepped according to the use of different tube diameters expander.
During use, needing the pipe box of enlarging on cylinder 11, opening oil pump, oil cylinder 3 will push up expander roll 6 to sinciput, utilization top
Inclined-plane on expander roll 6 makes slide block 5 expand outwardly, and cylinder 11 enlarged-diameter, pipeline enlarging to be processed completes, and pulls commutation
Valve makes top expander roll 6 draw back, and slide block 5, under back-moving spring 8 effect, returns back to original position, is that next operation is ready.
Cylinder 11 is made notch cuttype, and a set of slide block 5 just can process the pipeline of several different-diameter.
Above by embodiment, the present invention is described in detail, but described content has been only presently preferred embodiments of the present invention, no
The practical range for limiting the present invention can be considered.All equalizations made according to the present patent application scope change and improvement etc., all should
Still belong within the patent covering scope of the present invention.
