Description
Technical field
The present invention relates to a kind of loop wheel machine processing method, 5.5 meters of large flange plane machinings of more particularly to a kind of loop wheel machine turntable
Method.
Background technology
Loop wheel machine is the popular address of crane, is had widely in a series of heavy industry products such as ship, equipment, machinery, mould
Using.Loop wheel machine is made up of power set and support two parts.Power set are by motor, decelerator, clutch, brake, rope
The composition such as cylinder and steel wire rope.Motor is designed with the power-off i.e. mechanism of braking to be close to magnetic-type single-phase condenser motor；Motor also fills
There is thermoswitch, motor overheating can be prevented and burnt；Reductor is two-stage The gear deceleration, is fixed on motor；Clutch, brake
It is integrated with rope roll dress, but when clutch be in disengaged position, achievable rapid decrease, operational brake can control decrease speed
To avoid impacting.The circular hole that power set outer casing frontispiece is opened can be used to install hair-dryer, and user can be equipped with as needed
Hair-dryer carries out pressure cooling.The mobile jib and cursor composition that holder part is made up of screw rod, very heavy nut and vertical rod.Cursor
360 degree can be rotated on mobile jib, arm end be provided with travel switch with anti-operation failure or button failure and caused by lifted by crane position
Accident.Operation button starter realize motor positive and inverse can by wire rope roll around, decontrol, and lifted by crane by holder part pulley,
Object is transferred to complete lifting job.
In loop wheel machine, when being remaining part connection for loop wheel machine turntable, the mode of flange connection is often used.It is existing
Have that the bore for the flange that a loop wheel machine uses is bigger, and its diameter has reached 5.5 meters, is put down to this kind of bigbore flange
Face on milling machine when being processed, and because its bore is larger, after milling terminates in first time, does not ensure that the smooth of its surface
Degree, thus just need subsequently it is secondary, carry out finishing processing three times or even more frequently after, can be only achieved necessary requirement, step
Cumbersome, operating efficiency is not high.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of easy to process, the loop wheel machine turntable subsequently repaired is reduced with 5.5 meters greatly
Flange Plane processing method.
In order to solve the above technical problems, the technical scheme is that：A kind of loop wheel machine turntable is added with 5.5 meters of large flange planes
Work method, its innovative point are：The process steps are：
a）Flange is fixed：First, a diameter of 5.5 meters of large flange to be processed is arranged on milling machine, and it is fixed；
b）Rough mill：Then, the plane of large flange is rough milled using the disc knife of four angle of throat pieces, during rough milling, disk
The rotating speed of shape knife is 80r/ rice in, and feed velocity is 0.25 meter of rice/r；
c）Finish-milling：Finally, finish-milling, during finish-milling, disk are carried out to the plane of large flange using the disc knife of 3-edge surgical knife piece
The rotating speed of shape knife is 200r/ rice in, and feed velocity is 0.1 meter of rice/r, completes processing.
Further, the disc knife of the four angle of throats piece and the disc knife of 3-edge surgical knife piece are alloy knife.
The advantage of the invention is that：The processing method of the present invention, when being processed to Flange Plane, after first rough milling
The mode of finish-milling, and coordinate the rotating speed and feed velocity of disc knife, only need to by two step Milling Process can complete companion flange put down
The processing in face, without follow-up recondition, the flatness of Flange Plane is being ensure that, is substantially increasing processing efficiency.
Selection for disc knife, using alloy knife, also with alloy knife itself hardness height, good toughness, wear-resisting, heat-resisting
Characteristic, to ensure being smoothed out for Milling Process.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
5.5 meters of large flange plane surface processing methods of the loop wheel machine turntable of the present invention, are achieved by following step：
The first step, flange are fixed：First, a diameter of 5.5 meters of large flange to be processed is arranged on milling machine, and it is fixed.
Second step, rough mill：Then, the plane of large flange is rough milled using the disc knife of four angle of throat pieces, what is rough milled
During, the disc knife of four angle of throat pieces uses alloy knife, the selection for disc knife, using alloy knife, also with alloy knife
Hardness height itself, good toughness, wear-resisting, resistance to thermal property, to ensure being smoothed out for Milling Process, the rotating speed of disc knife is 80r/
Rice in, feed velocity is 0.25 meter of rice/r.
3rd step, finish-milling：Finally, finish-milling is carried out to the plane of large flange using the disc knife of 3-edge surgical knife piece, in finish-milling
During, the disc knife of 3-edge surgical knife piece uses alloy knife, the selection for disc knife, using alloy knife, also with alloy knife
Hardness height itself, good toughness, wear-resisting, resistance to thermal property, to ensure being smoothed out for Milling Process, the rotating speed of disc knife is
200r/ rice in, feed velocity are 0.1 meter of rice/r, complete processing.
The processing method of the present invention, when being processed to Flange Plane, by the way of rear finish-milling is first rough milled, and coordinates
The rotating speed and feed velocity of disc knife, the processing to Flange Plane need to can be only completed by two step Milling Process, without follow-up
Recondition, ensure that the flatness of Flange Plane, substantially increasing processing efficiency.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
Merely illustrating the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also have
Various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention
By appended claims and its equivalent thereof.
