Description
Technical field
This utility model is related to cutting equipment technical field and in particular to a kind of cutter and its cutter head assembly.
Background technology
The cutting of current metal tube, tank body or other tubing is mainly cut using electric saw cutting or using lathe car
Cut, but both cutting modes all can produce high temperature and a large amount of crumb powder, has high demands or tank for some processing environments
The internal situation containing hazardous chemical, it is even dangerous all to produce certain impact, and therefore extruding cutting is as chipless, low
Warm cutting mode, is widely used in such field.
Common pipe cutter is it is simply that extrude the conventional cutting tool of cutting, such as Chinese patent literature CN203778847U
Disclose a kind of Oil pipe cutter, including cutter body, described cutter body extends to blade, cutter body by knife root by knife face
It is provided centrally with installing hole, described knife face is full circle and knife face thickness is gradually increased to knife root by blade, although the prior art
Achieve that otch is neat, cutting process chipless, the installation in the hole of this cutter body wears installation axle, in extruding cutting operation
Cutter body rotates around installation axle, when cutting speed is too high, occurs to relatively rotate at a high speed, peace between cutter body and installation axle
Dress hole can produce heavy wear with the contact surface of installation axle, cause cutter body rotation unstable, affect otch regularity, cutting
Effect is poor, and the amount of heat being produced due to sliding friction, and the contact surface easily causing installing hole with installation axle occurs high temperature
Adhesion, impact cutter uses.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome extruding cutting cutter head in prior art easily to grind
Damage, the defect of high temperature adhesion, thus provide one kind adhesion not easy to wear, cutting effect more preferably cutter head assembly.
Further provide for a kind of cutter with above-mentioned cutter head assembly.
The technical solution adopted in the utility model is as follows：
A kind of cutter head assembly, including：Cutter head, including the revolving body forming axis hole, and is arranged on described revolving body
Blade on lateral wall；Cutter shaft, in described axis hole, described cutter head is rotatablely arranged on described cutter shaft, and described
It is provided with the circumferentially distributed multiple rollings that can roll along described cutter shaft along the circumference of described cutter shaft between cutter shaft and described axis hole
Kinetoplast, the rolling surface of described rolling element is contacted with the outside wall surface of described cutter shaft and the internal face of described axis hole simultaneously.
Multiple described rolling elements are the compact arranged multiple cylindrical rollers of circumference or needle roller along described cutter shaft.
The axial length of described rolling element is suitable with the axial length of described axis hole.
Described blade is the circular shear blade peripherally and outwardly extending formation from the surface of revolution of described revolving body.
The outward flange of described circular shear blade forms blade, and the thickness of described circular shear blade is from described revolution towards described blade
It is gradually reduced.
Described circular shear blade is in be symmetrical arranged up and down with described blade place plane for symmetrical plane.
Described revolving body is cylinder.
A kind of cutter, including：Cutter head connector, and the described cutter head assembly on described cutter head connector.
Cutter shaft installing hole is formed on described cutter head connector, described cutter shaft by be arranged in described cutter shaft install in the hole with
Described cutter head connector connects.
Described cutter shaft and described cutter shaft installing hole are interference fit.
Described cutter head connecting member forming has U-shaped frame, and two vertical portions of described U-shaped frame respectively correspondingly form one
Described cutter shaft installing hole, the upper end of described cutter shaft forms the cutter shaft positive stop lug boss that cannot pass through described cutter shaft installing hole, described
The lower end of cutter shaft be suitable to by upper under sequentially pass through two described cutter shaft installing holes, described cutter shaft is arranged on by way of hanging
On described cutter head connector.
Technical solutions of the utility model, have the advantage that：
1. the cutter head assembly that this utility model provides, including cutter shaft and be rotatablely arranged at the knife on described cutter shaft
Head, is provided with the circumferentially distributed multiple rollings that can roll along cutter shaft along the circumference of cutter shaft between cutter shaft and the axis hole of cutter head
Body, cutter member rotational band dynamic cutter head to be cut rotates, and cutter head rotates and drives rolling element to roll between axis hole and cutter shaft, the setting of rolling element
Put and the sliding friction between cutter shaft and the axis hole of cutter head is converted into shaft hole inner wall and rolling element and rolling element and cutter shaft outer wall
Between rolling friction, greatly reduce the abrasion to cutter head axis hole and cutter shaft, it is to avoid the high temperature adhesion of cutter head and cutter shaft, more
Be conducive to the smooth rotation of cutter head, otch is smooth, cutting effect more preferably, increased cutting-tool's used life.
2. the cutter head assembly that this utility model provides, blade is peripherally and outwardly to extend formation from the surface of revolution of described revolving body
Circular shear blade, the outward flange of circular shear blade forms blade, and the thickness of circular shear blade is from described revolution towards described blade gradually
Reduce, cutter member rotation to be cut, band dynamic cutter head rotates, the contact surface due to cutter head and cutter member to be cut increases with the penetraction depth of blade
Plus and increase, can prevent penetraction depth from increasing suddenly and swaging clamp occurs.
3. the cutter head assembly that this utility model provides, described circular shear blade with described blade place plane for symmetrical plane is in
Setting symmetrical above and below, so that blade uniform force in cutting process, treats cutting member extruding uniformly, otch is smooth.
4. the cutter head assembly that this utility model provides, cutter head connecting member forming has U-shaped frame, on two vertical portions of U-shaped frame
Correspondence forms cutter shaft installing hole respectively, and the upper end of cutter shaft forms cutter shaft positive stop lug boss, and cutter shaft can rely on self gravitation certainly
Upper and under hang between two cutter shaft installing holes, contact due to being burnishing surface between cutter shaft and cutter head, and cutter shaft and cutter shaft peace
The contact surface in dress hole is then more coarse, therefore during cutter head rotates relative to cutter shaft, even if the rotation of cutter shaft is unrestricted,
Also due to frictional resistance and substantially will not rotate, special cutter shaft fixed structure therefore need not be set again.
