Enclose and be not limited to the embodiment.
As illustrated in fig. 1 and 2, a kind of hollow circular-tube press, including frame, frame includes two collateral faggings 1, two sides
The horizontally disposed fixed station 3 of first fixed station 2 and second, and the first connecting plate being vertically arranged are connected between supporting plate 1
5.First fixed station 2 is located at the top of collateral fagging 1, and the second fixed station 3 is located at the middle part of collateral fagging 1, above-mentioned part composition
Frame.It is provided with first fixed station 2 on second cylinder 8, the second fixed station 3 and is provided with the first cylinder 7.
As shown in Figures 3 and 4, it is additionally provided with a support 4 in frame, support 4 passes through the company of being assembled to of slide rail 19 that is vertically arranged
On fishplate bar.Support 4 includes level table, the piston rod of the first cylinder 7 be connected with the latter half of the level table so that
Support 4 is driven to move.Pocketed springs on two the first guide pillars 9, the first guide pillar 9 are additionally provided with the first half of the level table
10；Lived provided with a pressing plate 22, the pressing plate 22 by its pilot hole opened up above the top of the first half of the level table
It is dynamic to be sleeved on two the first guide pillars 9, and be pressed under gravity on spring 10.The bottom surface of pressing plate 22 is symmetrical arranged two punchings
First 12, the bottom of drift 12 is provided with red needle 13.When the piston rod of second cylinder 8 stretches out, can push up the top of pressing plate 22 makes it
Move downward.The through hole passed through for drift 12 is opened up on level table, guide die 14 is installed in the bottom of level table.Support
4 bottom surface, which is provided with fixed block 21, fixed block 21, is horizontally disposed with the 3rd cylinder 18 and two second guide pillars 20.On second guide pillar 20
Movable set contiguous block 6, contiguous block 6 is connected with the piston rod of the 3rd cylinder 18.
As it can be seen in figures 5 and 6, opening up two inside feeding-passages of level 14.1 on the side wall of guide die 14 so that
One end of the feeding-passage 14.1 is in communication with the outside, and the other end is inside guide die 14.The top surface of guide die 14 opens up two
Individual charging hole 14.3 and two putty holes 14.2, its bottom surface opens up two discharge openings.Each feeding-passage 14.1 is respectively at one
Charging hole 14.3, a putty hole 14.2 are connected with a discharge opening, and putty hole 14.2 and corresponding discharge opening be located at it is same
On axis.Charging hole 14.3 is connected with feed pipe 11, and the diameter in putty hole 14.2 is less than the external diameter of drift 12 so that under drift 12
During drop can putty hole 14.2 block, and red needle 13 is inserted into putty hole 14.2.Taken out in feeding-passage 14.1 provided with one
Pull bar 15, the section of pumping rod 15 is adapted with the inwall of feeding-passage 14.1, and one end of pumping rod 15 is connected with contiguous block 6,
Place close to the other end opens up calibration hole 15.1, when calibration hole 15.1 can align with putty hole 14.2, the lucky energy of red needle 13
Insert in the calibration hole 15.1.When the piston rod of the 3rd cylinder 18 stretches out, pumping rod 15 is moved to the inner of feeding-passage 14.1
It is dynamic, charging hole 14.3 and discharge opening are blocked successively；When piston rod shrinks, pumping rod 15 is moved to the outer end of feeding-passage 14.1
It is dynamic, charging hole 14.3 is connected with discharge opening.One extruder head 16 is installed at discharge opening, the extrusion cavities 16.1 on extruder head 16
Diameter is more than the diameter of red needle 13 so that when in the insertion extrusion cavities 16.1 of red needle 13, outer wall and the extrusion cavities 16.1 of red needle 13
Toroidal cavity is formed between inwall, so that material is extruded into hollow circular-tube.
As shown in FIG. 7 and 8, locating piece 17 is additionally provided with the first connecting plate 5, when the 3rd cylinder 18 works, contiguous block 6 can
It can not further be moved under the constraint of locating piece 17, serve spacing fixation.
Working process and principle of the invention：
First, start feeder apparatus, raw material is entered by feed pipe 11 in feeding-passage 14.1.Now pumping rod 15 is in and stretched
Do well, connected between charging hole 14.3 and discharge opening.Now the second cylinder 8 starts, and its piston rod stretches out, and is touching pressing plate
Band dynamic pressure plate 22 is moved downward when 22, and in the through hole on the insertion level table of drift 12, and red needle 13 then passes through putty hole 14.2
Insert in extrusion cavities 16.1, because the diameter in putty hole 14.2 is less than the diameter of drift 12, therefore drift 12 is by putty hole 14.2
Block, prevent raw material from flowing out from there.Due to forming toroidal cavity between red needle 13 and extrusion cavities 16.1, therefore raw material is from extrusion cavities
16.1 out when self-assembling formation open circles tubular-shaped structures.
After tubulation terminates, the 3rd cylinder 18 start pumping rod 15 is fashionable to the interpolation of guide die 14, pull plate first will
Charging hole 14.3, which is blocked, makes it not feed, and then shrinks its piston rod in the second cylinder 8 of control, pressing plate 22 is in spring 10
It is raised above resetting under elastic potential energy effect.Red needle 13 and drift 12 are extracted out from extrusion cavities 16.1 and putty hole 14.2 respectively.
Then pumping rod 15 is continued to move to block in putty hole 14.2 and discharge opening, and whole feeding-passage 14.1 is completely enclosed.When taking out
When pull bar 15 is moved to extreme position, red needle 13 is inserted into the calibration hole 15.1 of pumping rod 15 when restarting the second cylinder 8, with
Anti- external force makes the bending damage of red needle 13.
During pipe extrusion forming, the length in the insertion extrusion cavities 16.1 of red needle 13 also determines the matter of pipe
Amount, therefore the height of support 4 is adjusted by the first cylinder 7, so that it is guaranteed that the quality of product.In pumping rod 15 to guiding
During being inserted in mould 14, the raw material remained in feeding-passage 14.1 can be extruded from extrusion cavities 16.1, prevented
The inner excessive raw material of accumulation of feeding-passage 14.1 is resulted in blockage, it is ensured that the normal of equipment is used.In use, can be different by changing
The red needle 13 of diameter, produces the tubing of different wall.
Above-described embodiment is preferably embodiment, but embodiments of the present invention are not by above-described embodiment of the invention
Limitation, other any Spirit Essences without departing from the present invention and the change made under principle, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
