Abstract
A kind of combined type forming cutter is the utility model is related to, belongs to cutting tool technical field.It is made up of the first cutter hub and the second cutter hub；The rear end of first cutter hub is provided with handle of a knife, and the front end of the first cutter hub is provided with the second cutter hub, and the first described cutter hub is step-like diameter-changing body, and the first cutter hub on each step before rear by being sequentially installed with the first blade, the second blade and the 3rd blade.The combined type forming cutter is simple in construction, and practicality is good, has obvious advantage compared to existing machine folder forming cutter, welding fabrication knife.Solve existing forming cutter because reasons in structure causes in process the shake of steering gear housing hair, main aperture is coarse leaves tool marks, cause the quality problems such as shell inner hole dimension overproof；It is stable with processing dimension, the characteristics of being convenient for changing after edge wear, product quality is effectively improved, there is positive meaning to preventing the wasting of resources, reducing cost of manufacture, used especially suitable for hole machined in steering gear Al-alloy casing.
Description
Technical field
A kind of combined type forming cutter is the utility model is related to, belongs to cutting tool technical field.
Background technology
In to steering gear Al-alloy casing during hole machined, to avoid processing main aperture with spiral reamer secondary clamping, that is, exist
Generally all it is to use to lengthen forming cutter, once to complete to process during the stepped hole of boring both ends.But due to the draft angle of steering gear housing
Degree, main aperture is deeper, and blank allowance is bigger.Existing machine presss from both sides forming cutter due to reasons in structure, when cutting main aperture, because of blade contact face
Product, dynamics is limited and main aperture surplus is big, make steering gear housing hair shake, main aperture is coarse and has tool marks, cause shell inner hole size to surpass
The quality problems such as difference.
When processing endoporus using whole welding type forming cutter, although being not in that cutting dynamics is inadequate, shell inner hole is caused
The quality problems such as dimension overproof.But welded type forming cutter, blade can not be changed.Cutter uses for a long time, after serious wear, with regard to nothing
Method is using, can only the new cutter of integral replacing.Number of cutters demand is more, increases cutter making cost, causes great resource
Waste.
The content of the invention
The purpose of this utility model is：Offer one kind is simple in construction, practicality is good, and processing dimension is stable, blade mill
It is convenient for changing after damage, answers reasons in structure to cause in process the shake of steering gear housing hair, main aperture thick with solve existing forming cutter
It is rough to leave tool marks, cause the combined type forming cutter of the quality problems such as shell inner hole dimension overproof.
The technical solution of the utility model is：
A kind of combined type forming cutter, it is made up of the first cutter hub and the second cutter hub；It is characterized in that：The rear end of first cutter hub
It is provided with handle of a knife, the front end of the first cutter hub is provided with the second cutter hub, and the first described cutter hub is step-like diameter-changing body, and first
Cutter hub on each step before rear by being sequentially installed with the first blade, the second blade and the 3rd blade.
The first described blade is a sword section blade, and the second blade is a sword chamfering blade.
The cutting edge of the 3rd described blade is two-edged.
Described the first blade, the second blade and the 3rd blade is respectively carbide chip.
The front end termination of the first described cutter hub is provided with screwed hole, and one end of the second cutter hub is provided with screw rod, the first knife
Connected between body and the second cutter hub by screwed hole with the matching thread of screw rod.
Cutting edge is axially evenly equipped with the second described cutter hub circumference, described cutting edge quantity is four.
The utility model has the advantage of：
The combined type forming cutter is simple in construction, and practicality is good, has compared to existing machine folder forming cutter, welding fabrication knife more apparent
Advantage.Solve existing forming cutter because reasons in structure causes in process the shake of steering gear housing hair, main aperture is coarse leaves
Tool marks, cause the quality problems such as shell inner hole dimension overproof；It is stable with processing dimension, the spy being convenient for changing after edge wear
Point, effectively improves product quality, has positive meaning to preventing the wasting of resources, reducing cost of manufacture, especially suitable for turning
Into device Al-alloy casing, hole machined uses.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, cutting edge, the 2, second cutter hub, the 3, the 3rd blade, the 4, second blade, the 5, first blade, the 6, first cutter hub,
7th, handle of a knife.
Embodiment
The combined type forming cutter is made up of the first cutter hub 6 and the second cutter hub 2；The rear end of first cutter hub 6 is provided with handle of a knife 7,
The front end termination of first cutter hub 6 is provided with screwed hole, and one end of the second cutter hub 2 is provided with screw rod, the first cutter hub 6 and the second cutter hub
Connected between 2 by screwed hole with the matching thread of screw rod；Four cutting edges 1 are axially evenly equipped with the circumference of second cutter hub 2.
First cutter hub 6 is step-like diameter-changing body, and the first cutter hub 6 on each step before rear by being sequentially installed with the first knife
Piece 5, the second blade 4 and the 3rd blade 3.First blade 5 is a sword section blade;Second blade 4 is a sword chamfering blade；3rd
The cutting edge of blade 3 is two-edged.First blade 5, the second blade 4 and the 3rd blade 3 are respectively carbide chip.
The combined type forming cutter is simple in construction, and practicality is good, and during work, the combined type forming cutter passes through handle of a knife 7 and bore hole
Equipment connects, and passes through screw lock.Shell workpiece to be processed is positioned by fixture again and clamped, starts special plane bore hole and sets
It is standby, you can to cut main aperture by the mobile cutting endoporus of both ends unit head, and by the cutting edge 1 of lengthening.The combined type is molded
Knife can avoid shake during existing forming cutter processing housing because the cutting edge 1 and main aperture contact area of lengthening are big, cutting great efforts
It is dynamic, the quality problems such as cause main aperture coarse and have tool marks, hole size overproof.First cutter hub 6 of the combined type forming cutter and
Connected between two cutter hubs 2 by screwed hole with the matching thread of screw rod；Therefore the replacing side after the blade abrasion of the first cutter hub 6
Just, and carbide chip has the advantages of cost is low.After the cutting edge 1 of second cutter hub 2 wears, the second cutter hub can be individually replaced
2, solve the problems, such as it is existing can only the new cutter of integral replacing cause the wasting of resources.To preventing the wasting of resources, reducing cost of manufacture
With positive meaning.
