Description
Technical field
The invention belongs to through-hole manufacture fields, more specifically more particularly to a kind of steel construction machining process for through hole.
Background technique
In structure steel fabrication the big through-hole of some sizes often because material need bending, edge rolling and cannot be pre-machined out
Come.And because there is shape after steel structure forming, drilling difficulty increases, borehole accuracy decline, and the efficiency of processing and manufacturing is extremely low
Under.Twist Drill can be used by processing through-hole on steel construction under normal circumstances, can also use radial drill boring cutter bore hole etc.
Processing method.With Twist Drill low efficiency, simultaneous processing range is smaller, is typically only capable to the hole of processing D25.It is big for size
Hole, need substep process, then first machining small is gradually increased to required size.Since fluted drill length is longer, drill core is straight
Diameter is small and poor rigidity, and has the influence of chisel edge, and drill bit is easy deflection, and aperture is easy to expand, and the surface quality in hole is poor, when drilling
Axial force is big.This processing method is time-consuming and laborious, and production efficiency is low, and machining accuracy is low, and cost of labor is very high.Another method
It is to process hole using through-hole boring cutter using radial drill.Still need subdrilling bottom outlet before bore hole, using bottom outlet as support guide, so
Boring cutter bore hole is utilized afterwards.It needs repeatedly to adjust cutter head overhang in process, needs size until being worked into, processing efficiency is low,
And machining accuracy is poor.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of steel construction machining process for through hole
Problem.
To achieve the above object, the invention provides the following technical scheme:
A kind of steel construction machining process for through hole, includes the following steps:
S1, selection through-hole machining machine and tool, and check whether equipment is complete, normal, related mating implements are complete complete and the examination that is switched on
Operation, contrast process drawing and material object confirm errorless rear progress perforation processing work；
S2, will be with drilling-workpiece fixation, by workpiece surface wiped clean by fixture, and draw using ruler the side ring in hole
The center of circle and；
S3, by starting to drill after the quick positioning and guiding of hollow boring bit thimble, first adjusting drill speed be 100-130r/min,
Slowly feeding drill bit, the drill bit amount of feeding are that 0.3mm/s rises to drill speed when in the complete immersed hole in bit point of the drill part
220-350r/min uses the cooling bore position of room temperature cooling liquid continual rinsing in boring procedure；
After the completion of S4, drilling are preliminary, drill bit is exited, and replace reaming bit, the adjusting reaming bit amount of feeding to 0.6mm/s, and
Adjusting reaming bit revolving speed is 110-175r/min, and hole is extended at the annulus marked in S2, and polishing is used after the completion of reaming
Machine carries out polishing deburring processing.
Preferably, keep the flushing of coolant liquid cooling in reaming and bruting process in S4, this setting ensure that workpiece is beaten
The whole process of hole machined is cooling, avoids the excessively high influence drilling quality of temperature or damage drill bit.
Preferably, adjusting workpiece perforated surfaces are vertical with drill bit after workpiece is fixed in S2, and the flatness of workbench should control
In 0-2mm.
Compared with prior art, the beneficial effects of the present invention are: the present invention is compared with conventionally by processing, worker is reduced
Labor intensity improves processing efficiency, improves hole machined precision, save the cost, and hole is extended to processing ruler by reaming
Very little, machining accuracy is high, reliable in quality.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
A kind of steel construction machining process for through hole, includes the following steps:
S1, selection through-hole machining machine and tool, and check whether equipment is complete, normal, related mating implements are complete complete and the examination that is switched on
Operation, contrast process drawing and material object confirm errorless rear progress perforation processing work；
S2, will be with drilling-workpiece fixation, by workpiece surface wiped clean by fixture, and draw using ruler the side ring in hole
The center of circle and；
S3, by starting to drill after the quick positioning and guiding of hollow boring bit thimble, first adjusting drill speed be 100-130r/min,
Slowly feeding drill bit, the drill bit amount of feeding are that 0.3mm/s rises to drill speed when in the complete immersed hole in bit point of the drill part
220-350r/min uses the cooling bore position of room temperature cooling liquid continual rinsing in boring procedure；
After the completion of S4, drilling are preliminary, drill bit is exited, and replace reaming bit, the adjusting reaming bit amount of feeding to 0.6mm/s, and
Adjusting reaming bit revolving speed is 110-175r/min, and hole is extended at the annulus marked in S2, and polishing is used after the completion of reaming
Machine carries out polishing deburring processing.
Specifically, keeping the flushing of coolant liquid cooling in reaming and bruting process in S4, this setting ensure that workpiece is beaten
