Description
Technical field
The present invention relates to a kind of machine tool, in particular to a kind of leg-chord pipe laterally U-shaped retaining wall on slope special-purpose milling cutter and
Its processing method.
Background technique
With the development of the industries such as petroleum, chemical industry, welding profession is also developed therewith, and the application of groove seems increasingly
Extensive and important, marine worker working ship spud leg main chord tube transverse direction retaining wall on slope, what is started is slotting cutter adduction gold finger cutter, is used
The tool sharpening concrete operations technique is as follows:
Workpiece is fixed: two contour V-type seats is installed on boring and milling machine workbench, spacing and processing length are suitable, blending bolt
V-type seat and boring and milling machine workbench are securely joined together, leg-chord pipe is placed on V-type seat, and leg-chord pipe is fixed
Securely, working position is towards main shaft.
Calibration of workpieces: horizontal direction is because V-type seat is contour, and the outer circular error of string pipe does not have to correction within 1mm, and rectilinear direction is used
Dial gauge beats string pipe side, and always by worktable rotary straightening both ends, string pipe will process U-type groove position and be adjusted to side with jack
Face highest point.
Machining: (1) lift adjustment of machine tool chief axis Y-direction is located in the pipe U-shaped slot center of string；(2) first time lathe master
25 slotting cutter of axis clamping φ, every knife Z-direction enter 3 ~ 5mm, and X is to mobile 2140mm, until Z-direction reaches 15mm；(3) second of clamping
16 slotting cutter of import φ, the every feed of knife Z-direction 2 ~ 4mm, X are to mobile 2140mm, until Z-direction reaches 32mm；(4) third time clamping is fixed
The molding of system refers to knife, and the every feed of knife Z-direction 3 ~ 4mm, X are to mobile 2140mm, until Z-direction reaches 42mm.
The examination and test of products: it detects whether to meet drawing requirement by forming cubing.
1 string pipe can only be just processed with the cutter and method 8 hours, since the bad required place processed of processing conditions is deposited
The abrasion and fracture of slotting cutter and alloy finger-type knife are easily caused in a large amount of welding slag, so 1 string pipe needs 4 of processing are slotting cutter
With 2 alloy finger cutters, processing 1 string pipe will wear and can not use, the processing effect in the processing of this condition
Rate and economic benefit be not high, while being also unable to satisfy company's production needs.
Patent CN206588399 discloses the cutting special-purpose milling cutter of the tube body groove based on groove special purpose machine tool, the dedicated milling
Knife is Split type cutter, is mainly made of cutter hub, blade and knife handle, and wherein cutter hub is the maize milling cutter pattern with 30 ° of tapers,
Blade is evenly distributed on the conical surface of cutter hub, and cutter hub is connect with knife handle.Its cutter hub is the corn type cutter with taper, and blade is uniform
It is distributed on the cutter hub conical surface, which is unilateral processing, is unable to complete the processing of U-shaped groove.
Summary of the invention:
To solve the above-mentioned problems, the present invention provides a kind of leg-chord pipe laterally U-shaped retaining wall on slope special-purpose milling cutters, including cutterhead

Specific 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 the embodiment described range.
As shown in Figure 1, 2, the present invention provides a kind of leg-chord pipe laterally U-shaped retaining wall on slope special-purpose milling cutters, including cutterhead 2
With the taper knife handle 1 being fixedly connected among knife 2,6 two sides of cutter hub is peripherally disposed blade installation slot, wherein knife
Piece mounting groove is divided into blade installation slot a4, blade installation slot b3 and blade installation slot c7, and the blade installation slot is pacified according to blade
Tankage a4- blade installation slot c7- blade installation slot b3 sequence is opened in 6 surface of cutter hub, blade be bolted be installed in
In blade installation slot, the disc type milling cutter pattern that 6 taper of taper cutter hub is 10 °, the cutter hub 6 is with a thickness of 60mm, the knife
2 diameter of disk is 380mm, and blade tip of the invention has circular arc, and both sides shape simultaneously, can disposably work the work piece into U
Shape.The distance at blade installation slot a4 to 2 center of cutterhead is 147mm, and the distance at the blade installation slot b3 to 2 center of cutterhead is
The distance at 180.5mm, the blade installation slot c7 to 2 center of cutterhead is 165mm, and knife handle 1 connects by the way that bolt and cutter hub 6 are fixed
It connects, 1 structure of knife handle can be matched with machine tool chief axis 5, and the blade has 30, and 30 blades are divided into two groups, every group
There are 15 blades, the taper of the blade is consistent with 6 taper of cutter hub, and blade edge is arc-shaped.
As shown in figure 3, including that workpiece is fixed, corrected with the method for the lateral U-shaped groove of special-purpose milling cutter processing leg-chord pipe
Four workpiece, machining and product inspection steps, the specific steps are as follows:
Workpiece is fixed: two contour V-type seats is installed on boring and milling machine workbench, spacing and processing length are suitable, blending bolt
V-type seat and boring and milling machine workbench are securely joined together, leg-chord pipe is placed on V-type seat, and leg-chord pipe is fixed
Securely, working position is towards top.
Calibration of workpieces: horizontal direction is because V-type seat is contour, and the outer circular error of string pipe does not have to correction within 1mm, and rectilinear direction is used
Dial gauge beats string pipe side, always by worktable rotary straightening both ends, corrects simply, does not have to jack and adjust, cutting adds
The completion of one knife of working hour is high-efficient, high without knife comprehensive quality is connect, and cutter consumption is few at low cost.
Machining: knife handle and 4 clamping of machine tool chief axis form, and cutterhead is moved forward and backward adjustment positioning, make cutterhead mid-depth
It is directed at the pipe U-shaped slot center of leg-chord, if cutterhead 2 is Y-direction in leg-chord pipe depth direction, cutterhead 2 is in leg-chord pipe movement side
To being X to carrying out machining to Y-direction along X, Y-direction is 35 ~ 42mm from leg-chord pipe surface depth, and 2 revolving speed of cutterhead is
150r/min, feed 200mm/min.
The examination and test of products: it detects whether to meet drawing requirement by forming cubing.
With the present invention finished edge special-purpose milling cutter become now, cutter are transformed and optimized using the hobboing cutter scrapped
Processing efficiency and all big promotion of economic benefit after transformation, spud leg main chord tube is exerted oneself in the processing Shanghai NCA1932 moral in workshop before
When lateral groove processing work, 1 string pipe can only be just processed within 8 hours, since the bad required place processed of processing conditions exists
A large amount of welding slag easily causes the abrasion and fracture of slotting cutter and alloy finger-type knife, thus 1 string pipe of processing need 4 slotting cutter with
2 alloy finger cutters, processing 1 string pipe will wear and can not use, and can process 7 string pipes, every processing within present 8 hours
10 string pipes only need to change a blade.
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
It is merely illustrated the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also has
Various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention
It is defined by the appending claims and its equivalent thereof.
