Abstract
The utility model discloses a polishing belt for polishing shaft parts, which comprises a substrate layer, a bottom glue layer coated on the substrate layer, abrasive particles bonded on the bottom glue layer and a compound glue layer for further fixing the abrasive particles, wherein the top of the abrasive particles extends out of the compound glue layer; abrasive material granule between leave the space that forms the chip removal passageway, the projected area of space on the substrate layer accounts for 20% ~ 40% of whole substrate layer area. The polishing belt has higher polishing efficiency during polishing, can better meet the requirement of finish degree, and is particularly suitable for polishing shaft parts such as crankshafts, camshafts, gear shafts and the like.
Description
Technical Field
The utility model belongs to the abrasive material field, concretely relates to polishing belt that is used for bent axle camshaft and other axle types polishing.
Background
The power assembly of the automobile comprises a plurality of shaft parts such as a crankshaft, a camshaft and a gear shaft, and the shaft parts often move relatively at a high speed with each other or with other parts, so that the friction force between the parts needs to be reduced as much as possible, therefore, the surface finish of the shaft parts has higher requirements, and the polished shaft parts have higher finish.
The crankshaft and the camshaft are mainly made of nodular cast iron and forged steel, and the material has high hardness, so that the material has high requirements on the cutting force of a polishing belt during polishing. When the existing polishing belt polishes the components, the requirements of polishing efficiency and finish degree are hardly met.
SUMMERY OF THE UTILITY MODEL
the utility model provides a polishing belt for polishing of axle type part, this polishing belt be particularly suitable for polishing of axle type parts such as bent axle, camshaft and gear shaft, have higher efficiency of polishing when polishing to can satisfy the smooth finish requirement betterly.
A polishing belt for polishing shaft parts comprises a substrate layer, a bottom glue layer coated on the substrate layer, abrasive particles bonded on the bottom glue layer and a compound glue layer for further fixing the abrasive particles, wherein the top of each abrasive particle extends out of the compound glue layer;
abrasive material granule between leave the space that forms the chip removal passageway, the projected area of space on the substrate layer accounts for 20% ~ 40% of whole substrate layer area.
Preferably, the part of the abrasive particles positioned on the bottom glue layer accounts for 1/4-1/3 of the height of the abrasive particles;
the abrasive particles are positioned on the compound adhesive layer, and the part of the abrasive particles positioned on the compound adhesive layer accounts for 1/4-1/3 of the height of the abrasive particles.
Preferably, the other surface of the substrate layer is provided with an anti-slip layer.
preferably, the substrate layer is a PET polyester film.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) The utility model arranges a reasonable chip removal channel on the surface of the polishing sheet, so that metal chips can be discharged in time during polishing, thereby improving polishing efficiency on one hand, preventing the chips from damaging the surface of the component and improving finish degree on the other hand;
(2) The 1/2-2/3 part of the grinding particles of the polishing pad is covered by the bottom rubber layer and the compound rubber layer, and 1/2-2/3 part of the grinding particles is exposed outside, so that the polishing pad has higher cutting force and firm combination, and is favorable for prolonging the service life of the polishing pad;
(3) The utility model discloses an adopt specific PET polyester film, have compliance and stiffness concurrently, provide the support that grinds the needs.
Drawings
FIG. 1 is a schematic view of the polishing belt of the present invention;
FIG. 2 is a side cross-sectional view of the polishing belt of FIG. 1;
Detailed Description
The polishing belt of the present invention will be further described with reference to the accompanying drawings.
Known by the schematic structure diagram of the polishing belt shown in fig. 1 and fig. 2, the utility model discloses a polishing belt includes skid resistant course, substrate layer, primer layer, abrasive material layer and compound glue film by supreme down in proper order, and wherein, the abrasive material layer comprises abrasive material granule.
The grain diameter of the abrasive particles forming the abrasive layer is 6-45 microns, gaps forming chip removal channels are reserved among the abrasive particles, the projection area of the gaps on the base material layer accounts for 20% -40% of the area of the whole base material layer, the chip removal capacity of the polishing sheet can be effectively improved through the gaps, and damage of chips to components is reduced.
the utility model discloses in, abrasive material granule part buries the glue film (including primer layer and compound glue film), and the glue film surface is exposed to the part, and particularly, the part that abrasive material granule is located the primer layer accounts for the 1/3 of abrasive material granule height, and the part that abrasive material granule is located compound glue film accounts for the 1/3 of abrasive material granule height, and the part that abrasive material granule exposes the glue film surface accounts for the 1/3 of abrasive material granule height, and this polishing pad had both possessed the cutting power, had better adhesive force again.
the utility model discloses a substrate layer is PET polyester film, and this PET polyester film has compliance and stiffness concurrently, provides the support that grinds the needs.
The above-mentioned detailed description of the technical solution and the beneficial effects of the present invention have been described in detail, it should be understood that the above is only the most preferred embodiment of the present invention, not used for limiting the present invention, any modification, supplement, equivalent replacement, etc. made within the principle scope of the present invention should be included within the protection scope of the present invention.
