The content of the invention
In view of above-mentioned problems of the prior art, have and necessarily the structure of the cutting machine are improved.The present invention
A kind of Profile cut-off machine with novel pincers device, including axially extending frame are proposed, cutting is provided with the frame
Knife and the Tongs device attached to crane for ship building for clamping section, it is characterised in that the Tongs device attached to crane for ship building has the cutting chuck of two groups of geo-stationary arrangements,
I.e. first cutting chuck and the second cutting chuck；The first cutting chuck has a pair of material folding heads, at least one of which material folding
Head is the first activity material folding head that can move back and forth, and described second, which cuts chuck, has a pair of material folding heads, at least one of which
Material folding head is the second activity material folding head that can move back and forth；The first cutting chuck and the second cutting chuck are front and rear vertically
It is arranged side by side, the cutting gap for avoiding the cutter is reserved between the described first cutting chuck and the second cutting chuck,
The cutter correspond to the cutting gap arrangement；The Tongs device attached to crane for ship building also includes power distributor, the power distributor energy
It is enough to drive the first activity material folding head and the second activity material folding head each mobile so that described to direction is closed up respectively
First cutting chuck and the second cutting chuck can form and various sizes of tighten up jaws.
Wherein, the frame is the architecture of whole equipment, for supporting the components such as the cutter, Tongs device attached to crane for ship building.Institute
State that frame is axially extending to refer to that the frame axially extends on the whole, but and exclude to have in the frame and radially extend
Part.It should be noted that the axial direction is the length bearing of trend of the frame, also it is placed on the cutting chuck
Strip section bar length bearing of trend, perpendicular direction be defined as radially.In case of no particular description, originally
Axial direction that text is mentioned to, radially it is used uniformly above-mentioned definition.
Wherein, the Tongs device attached to crane for ship building is mainly used in clamping cut section bar nearby when cutting section bar, and it mainly passes through two
The group cutting chuck, i.e., described first cutting chuck and the second cutting chuck are completed to clamp appointing for cut section bar
Business.Chuck is cut described in two groups all has a pair of material folding heads respectively, and a pair of material folding heads relative can move back and forth；It is or therein
One material folding head moves back and forth (this material folding head is referred to as activity material folding head), and another charging head is fixed that (this material folding head claims
For geometrical clamp material head), the geometrical clamp material head of chuck is cut described in two groups can use split-type structural, but be in order at simplified structure
Purpose, described in two groups cut chuck geometrical clamp material head can also use integral structure.
It should be noted first from the point of view of relative placement position relation on the Tongs device attached to crane for ship building, cut described in two groups
Cut the relation that chuck is geo-stationary, i.e., during work is cut, the first cutting chuck and the second cutting chuck
Between can't relatively move, there is metastable position relationship between them.But them are not precluded from together in the machine
Slided on the guide rail of frame, be more not precluded within before cutting work starts and chuck is cut to the described first cutting chuck and described second
Position is adjusted so that being reserved with the cutting gap of suitable width between them.Secondly come from the mode of clamping section
See, the clamping movement that chuck is cut described in two groups is relatively independent relation, i.e., the first activity folder of described first cutting chuck
The movement of material head can't hinder the movement of the second activity material folding head of the second cutting chuck, and vice versa, so that two groups
The cutting chuck each opening and closing can adjust to be formed and various sizes of tighten up jaws.Such as the receipts when the described first cutting chuck
When to grip mouth be 50mm, the second cutting chuck can tighten up folder according to the diameter adjustment of its own required clamping section
The size of mouth, such as 51mm.The jaws of tightening up refers to, when the cutting chuck clamps section bar, be formed at the cutting
Grasping part between a pair of material folding heads of chuck itself.
Wherein, the cutting gap be provided in it is described first cutting chuck and second cutting chuck between space, one
As be arranged to wider 2mm~3mm than the thickness of the cutter.The cutting gap can be to be formed at spaced arrangement
The first cutting chuck and the second cutting chuck between clearance space, can also be to be formed at mutually by described the together
Sunk area between one cutting chuck and the second cutting.Because the width of the cutting gap is very small, described cut is placed on
The length of section bar in slot gap is also just very short.
Wherein, the power distributor is can to drive the first activity material folding head and the second activity material folding head each respectively
From to close up direction movement PTO.Certainly, when suitably adjust the power distributor with described first activity press from both sides
Material head, the second activity material folding head drive connection after, the power distributor can also drive the first activity material folding respectively
Head, the second activity material folding head move to direction is opened.
According to above-mentioned technical proposal, compared with prior art, advantageous effects of the invention are：
The cutting gap of the cutter, institute are avoided due to being reserved between the described first cutting chuck and the second cutting chuck
State cutter and correspond to the cutting gap arrangement.So, the first cutting chuck and the second cutting chuck are also just split in institute
The left and right sides of cutter is stated, the mode that the cutter can be passed into the cutting gap is cut while is clamped in
Section bar in the first cutting chuck and the second cutting chuck.Be clamped to when section bar to be cut described in same root simultaneously described in
When in the first cutting chuck and the second cutting chuck, the first cutting chuck and the second cutting chuck can be respectively its offer
The bite in the cutter both sides is split, the shaking amplitude for advantageously reducing cutting process medium section is smart so as to improve cutting
Degree.Another significant advantage is embodied in, because the described first cutting chuck and the second cutting chuck can not done mutually
Jaws size is tightened up according to what the diameter of clamped section bar adjusted itself with disturbing, so even if the section bar to be cut of minor diameter
With another section bar of major diameter enter it is described second cutting chuck in and cause it is described second cutting chuck can not clamp it is small
The section bar to be cut of diameter, the first cutting chuck remain able to clamp the section bar to be cut of the minor diameter.For example, when needs are cut
When cutting the material head of second section bar, the first paragraph of second section bar is clamped on the first cutting chuck, and material head
It is clamped to simultaneously in the second cutting chuck through the clout of the cutting gap and first section bar, even if now institute
The diameter for stating second section bar is less than the diameter of first section bar and causes the second cutting chuck to clamp institute the
A piece section bar and the material head of second section bar can not be clamped, it is described first cutting chuck itself still can be adjusted flexibly
Tighten up jaws size and clamp second section bar, so as to avoid cutting the paragraph header of second section bar during due to
Chucking power is insufficient and causes second section bar to occur substantially rocking.Secondly because the width of the cutting gap is very small,
The material head of second section bar can set very short and reduce cutting feed consumption rate, be additionally, since second section bar
Material head by described second cutting chuck clamped by, so cutting after can not richochet out hurt sb.'s feelings.In follow-up cutting second
During the tailing of section bar, if there is above-mentioned similar situation, similar effect can also be obtained.No matter so in tandem two
Whether the diameter dimension of root section bar is equal, always has a cutting chuck section bar to be cut can be clamped.It can be seen that
By adjusting the structure of the Tongs device attached to crane for ship building and the position of the cutter so that the cutting machine can solve the problem that in tandem
Two section bars enter in same cutting chuck and cause the section bar with major diameter to hinder the section bar to be cut with minor diameter
The problem of being clamped.
In order to realize the power drive of the first activity material folding head and the second activity material folding head, the power distribution
The structure of device is most important.In the application of reality, the power distributor can use multiple structural forms, such as：
The first, the power distributor is two separate drivers, and the output shaft of two drivers connects respectively
Connect the first activity material folding head and the second activity material folding head.Wherein, the driver can be the drive mechanisms such as cylinder,
The first activity material folding head and the second activity material folding head can not only be driven to be moved to direction is closed up, additionally it is possible to drive it
To open direction movement.This power distributor structure is relatively easy, but due to needing to set two drivers
And more installing spaces is taken, and cost is costly.Therefore, the present invention also proposes the described of second structure type
Power distributor.
Second, the power distributor includes that the first activity material folding head described in top pressure and second activity can be distinguished
Material folding head is each to the tilting plate and top pressing device for tilting plate described in top pressure for closing up direction movement；In the axial direction, the top
