Abstract
The utility model discloses a kind of nylon core and rolls tightly wheel, including nylon mandrel is made using adhesive bonding way bonding by polishing layer of sand, by the broken silk of nylon；Nylon mandrel offers through-hole along own axes direction；The excircle side wall of nylon mandrel is wound with multilayer polishing layer of sand to the direction far from nylon mandrel, is bonded between each layer of sand of polishing by epoxy resin glue；It is Nian Jie by epoxy resin glue between the polishing layer of sand of innermost layer and nylon mandrel；The sand grains mesh number of polishing layer of sand is -800 mesh of 240 mesh.Compared with prior art, the utility model can prevent from rolling tightly the nylon mandrel scratching product surface of wheel.
Description
Technical field
The utility model relates to roll tightly wheel field more particularly to a kind of nylon core to roll tightly wheel.
Background technique
It rolls tightly wheel and is generally used for metal sanding and polishing, roll tightly the polishing layer of sand that wheel includes tube core and is fixed on outside tube core.
Roll tightly wheel polishing layer of sand material generally using nylon as primary raw material, due to roll tightly wheel polishing layer of sand material and tube core material
Matter is different, and the material of tube core is generally plastic cement or wood, during continuous polishing, if after polishing layer of sand is worn out, tube core
It is directly contacted with product, it is easy to which the polishing quality that can reduce product surface keeps product surface roughness excessively high or even scratching；
In addition, the material of tube core and the material for rolling tightly wheel polishing layer of sand are inconsistent, therefore cause adhesive strength variant, bonding effect is not
It is good.
Utility model content
The utility model is to solve existing technological deficiency, provides a kind of nylon core and rolls tightly wheel, can prevent from rolling tightly
The tube core scratching product surface of wheel.Its specific technical solution is as follows:
The utility model discloses a kind of nylon core and rolls tightly wheel, including by polishing layer of sand, nylon mandrel；Nylon mandrel is along itself
Axis direction offers through-hole, doped with polishing sand grains on nylon mandrel；The excircle side wall of nylon mandrel is to far from nylon core
The direction of axis is wound with multilayer polishing layer of sand, is bonded between each layer of sand of polishing by epoxy resin glue；The polishing sand of innermost layer
Layer is Nian Jie with epoxy resin glue is passed through between nylon mandrel；The sand grains mesh number of polishing layer of sand is -800 mesh of 240 mesh；Nylon mandrel
Polishing sand grains mesh number with polishing the sand grains mesh number of layer of sand it is identical.
Further, through-hole side wall axially offers groove along itself.
The utility model has the beneficial effects that the nylon mandrel of the utility model is made of nylon material, therefore when polishing
Layer of sand wear when, even if nylon mandrel is contacted with product surface, will not scratching product surface or reduce product surface it is smooth
Degree；Nylon mandrel corner raw material remaining when can be by production polishing layer of sand is made, and improves resource utilization, reduces production
Cost；The material of layer of sand of polishing and the material of nylon mandrel include nylon, and therefore, the adhesive strength of the two is higher, is not easy
It loosens.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is the axial section structural schematic diagram of the utility model embodiment.
It is marked in figure: polishing layer of sand 100, nylon mandrel 200, through-hole 201, groove 202.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
The utility model is described in further detail below by specific embodiment combination attached drawing.Please refer to attached drawing.
The utility model discloses a kind of nylon core and rolls tightly wheel, including by polishing layer of sand 100, nylon mandrel 200；Nylon mandrel
200 offer through-hole 201 along own axes direction；Doped with polishing sand grains on nylon mandrel 200, specifically, nylon core is produced
Material used in axis 200 is that production rolls tightly leftover pieces remained by wheel polishing layer, and leftover pieces are rushed by the way of punching machine punching
It is pressed into 200 shape of nylon mandrel, is then punched into through-hole 201 by the way of punching machine punching press again；The excircle of nylon mandrel 200
Side wall is wound with multilayer polishing layer of sand 100 to the direction far from nylon mandrel 200, it is preferable that polishing layer of sand 100 is one section of strip
Emery cloth it is whole, the emery cloth of bar shaped winds package around the circumferential side wall from coil to coil of nylon mandrel 200, forms multilayer layer of sand structure；
It is bonded between each polishing layer of sand 100 by epoxy resin glue；Lead between the polishing layer of sand 100 and nylon mandrel 200 of innermost layer
Cross epoxy resin glue bonding；The sand grains mesh number of polishing layer of sand 100 is -800 mesh of 240 mesh；The polishing sand grains of different meshes, grain
Diameter is also different, doped with polishing sand grains, the mesh number and polishing layer of sand of the polishing sand grains of nylon mandrel 200 in nylon mandrel 200
The mesh number of 100 polishing sand grains is identical.The nylon mandrel 200 of the utility model is made of nylon material, therefore when polishing sand
When layer 100 is worn, even if nylon mandrel 200 is contacted with product surface, scratching product surface or product surface will not be reduced
Smoothness；The corner raw material remaining when can be by production polishing layer of sand 100 of nylon mandrel 200 is made, and improves the utilization of resources
Rate reduces production cost；The material of layer of sand 100 of polishing and the material of nylon mandrel 200 include nylon, therefore, the two
Adhesive strength is higher, is not easy to loosen.
Further, 201 side wall of through-hole is to increase nylon core along groove 202, the effect of groove 202 itself is axially offered
Transmission effect between axis 200 and the shaft of grinding apparatus prevents from skidding between shaft and nylon mandrel 200, alternatively, it is also possible to
Coated with adhesive is between 201 inner wall of shaft and through-hole of grinding apparatus come the bond properties that both improves.
The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that
The specific implementation of the utility model is only limited to these instructions.For the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made.
