Abstract
The invention relates to the technical field of cutting of large-thickness-board counter bored holes, in particular to a mold positioning automatic rotating cutting method of a large-thickness-board counter bored hole. The method comprises the steps that a, a through hole is formed in the round center position of the bored hole; b, a positioning mold is mounted on the through hole; and c, a cutting machine is arranged to do the circumferential rotation around the positioning mold. By the application of the technical scheme of the implementation, the positioning mold is utilized for positioning the round center, and the cutting machine does the circumferential motion around the round center, so that the round counter bored hole is formed through cutting. The positioning mold is utilized for positioning, and the cutting machine can carry out automatic cutting, so that the speed of counter bored hole cutting is improved, and construction safety is ensured. The appearance flatness of the counter bored hole can be ensured, and a large number of man hours and a large amount of labor are saved.
Description
Technical field
The present invention relates to heavy thickness plate counterbore cutting technique field, particularly a kind of mould location automatic rotation cutting method of heavy thickness plate counterbore.
Background technology
At building field, building high building underground peripheral frame huge post column base plate is connected with the rock bolt plug welding mode of boring a hole that adopts more.In order to realize this connected mode, must cut counterbore on the buried plate of heavy thickness, counterbore shape is trumpet type, and its maximum diameter of hole can reach 128mm.In the architectural process of reality, it is numerous that single-piece column base plate opens counterbore.Existing form of construction work is needing the position of cutting counterbore to adopt hand cut counterbore technique, and adopt hand cut method first cannot ensure the flat appearance of counterbore, if simultaneously cutting angle, that cutting speed controls is improper, very easily cause the significant deficiency such as the Aperture deviation of counterbore, main material scaling loss, more seriously in cutting process, liquid molten steel splashing can threaten to operator safety.Namely hand cut method cannot ensure presentation quality and the anchor pole penetration plug welding process operability of perforate, not only consuming time but also effort, cannot meet the quality requirement of component, also cannot guarantee construction safety and progress.
Summary of the invention
Embodiment of the present invention goal of the invention is the mould location automatic rotation cutting method providing a kind of heavy thickness plate counterbore, apply the speed that this technical scheme can improve cutting counterbore, ensure construction safety, the flat appearance degree of counterbore can also be ensured, save a large amount of man-hours and manpower.
In order to realize foregoing invention object, complete skill scheme of the present invention is:
A mould location automatic rotation cutting method for heavy thickness plate counterbore, comprises step:
A. through hole is offered at counterbore home position;
B. on described through hole, jig is installed;
C. cutting machine is set to make circular-rotation around this jig.
Optionally, step C, concrete
Cutting machine installs rocking arm, and described one end is movably connected on described jig, and take jig as the center of circle, described cutting machine does circular-rotation around described jig.
Optionally, described jig offers circle center hole, for connecting described rocking arm.
Therefore, application the present embodiment technical scheme, utilize jig positioning centre, cutting machine is circled around this center of circle, cut out a circular counterbore, the present invention utilizes jig to locate, cutting machine surface trimming, improves the speed of cutting counterbore, ensures construction safety, the flat appearance degree of counterbore can also be ensured, save a large amount of man-hours and manpower.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the stereogram of jig of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
embodiment 1:
The present embodiment provides a kind of mould location automatic rotation cutting method of heavy thickness plate counterbore, comprises step:
A. through hole is offered at counterbore home position;
B. on described through hole, jig is installed;
C. cutting machine is set to make circular-rotation around this jig.
Optionally, step C, concrete
Cutting machine installs rocking arm, and one end is movably connected on described jig, and take jig as the center of circle, described cutting machine does circular-rotation around described jig.
As Fig. 1, disclose a kind of specific embodiment of jig, jig offers circle center hole 101, in the present invention, jig is arranged on the through hole offered, and the circle center hole 101 of jig is for connecting the rocking arm of cutting machine, plays the effect of center of circle rotating shaft.Jig can be reused.
More specifically, the invention discloses the concrete cutting parameter of tubaeform counterbore:
The cutting flame temperature of cutting machine is also the more important, and cutting temperature is too high, easily occurs turned-down edge, scabs, cut surface is bad, the dross amount very much not phenomenon such as easy to clean in cutting process, and cutting temperature is too low, and cutting can be caused imperfect.Temperature is controlled then can solve the problem at 2800 ~ 2900 DEG C, both can ensure hole fly-cutting, can guarantee that again cut quality is good.
The cutting machine speed of service has significant impact for the stability of cutting process and the quality of cut surface, the too fast meeting of cutting speed makes cut surface occur the mass defects such as depression and dross, cutting speed is crossed and otch top edge then can be made slowly to melt turned-down edge, there is the defects such as puddle shape zanjon pit in the latter half, when to cut large footpath be the bellmouth orifice of 128mm, cutting speed controls can obtain optimum Cutting effect within the scope of 300 ~ 320mm/min, and when to cut large footpath be the bellmouth orifice of 92mm, cutting speed is controlled can obtain optimum Cutting effect within the scope of 370 ~ 390mm/min.
More particularly cutting the bellmouth orifice that oblique angle is 45 °, for ensureing the one-shot forming of cutting, flame rifle angle of inclination can be set as 45 °.
Above-described embodiment, does not form the restriction to this technical scheme protection domain.The amendment done within any spirit at above-mentioned embodiment and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technical scheme.
