Abstract

The utility model discloses a grinding wheel based on stacked grinding units. The grinding wheel comprises base materials, wherein the grinding units are solidified to the surfaces of the base materials; a gap is reserved between every two grinding units; the base materials are stacked in a surrounding mode with the surfaces facing upwards; the grinding units of every two adjacent base materials are staggered or crossed vertically; through holes are formed in the back face of the base material on the innermost side. The flexible materials prone to deformation form a grinding tool after being stacked and solidified, so that compaction, drying and calcination carried out when existing grinding wheels are machined are avoided. As the grinding units are arranged at intervals, grinding wheels meeting various grinding requirements can be easily arranged relatively. Due to the arrangement of the gaps between the grinding units, heat dissipation in the grinding process is facilitated, and grinding debris produced in the grinding process can be conveniently discharged.

Description

A kind of based on the stacked emery wheel of grinding unit

Technical field

The utility model belongs to grinding materials and grinding tool technical field, relates to a kind of based on the stacked emery wheel of grinding unit.

Background technology

Grinding materials and grinding tool, is the general designation of abrasive material and grinding tool, and grinding materials and grinding tool have the laudatory title of industrial tooth.In the time of grinding, conventional abrasive material or grinding tool carry out machining as grinding tool to the part of need processing, and reach certain technical requirement.

Abrasive product is mainly divided into corundum abrasive and the large class of silicon carbide abrasive two, specifically, substantially has following several: 1, brown corundum abrasive, main component is Al ₂o ₃, thering is hardness medium, toughness is large, and particle is sharp, and less expensive is applicable to the high metal of processing tensile strength.2, white fused alumina abrasive material, its hardness is a little more than brown corundum, but toughness is poor, easily cuts workpiece when grinding, and self-sharpening is good, and caloric value is less, and grinding capacity is strong, and efficiency is high.3, single alundum abrasive material, its particle is by single crystal composition, and has good many ribs cutting edge, and higher hardness and toughness, grinding capacity are strong, and grinding caloric value is few, and shortcoming is that production cost is higher, output is lower, so price comparison is high.4, black silicon carbide grain, green silicon carbide abrasive material, cubic silicon carbide abrasive material, cerium silicon carbide abrasive material etc., belong to silicon carbide abrasive, and Main Ingredients and Appearance is carborundum SiC, hardness is high, and fragility is large, and abrasive particle is sharp, thermal conductivity is better, and wearability is stronger, is relatively applicable to hard crisp metal and the non-metallic products of processing.

Grinding tool is the instrument in order to grinding, grinding and polishing.Most grinding tool is to add with abrasive material the artificial grinding tool that bonding agent is made, the natural grinding tool that also useful natural ore deposit rock is directly processed into.Grinding tool except being widely adopted, also for the processing of the nonmetallic materials such as grain processing, paper industry and pottery, glass, stone material, plastics, rubber, timber in machine-building and other metal-processing industries.

Grinding tool in use, in the time of abrasive particle blunt, because abrasive particle self part is cracked or bonding agent fracture, abrasive particle is local or come off completely from grinding tool, and constantly there is new cutting edge in abrasive material on grinding tool working face, or constantly expose new sharp abrasive particle, make grinding tool can keep within a certain period of time cutting ability.This self-sharpening of grinding tool is grinding tool outstanding feature compared with general cutter.Bonded abrasive tool, by the difference of abrasive material used, can be divided into conventional abrasive material bonded abrasive tool and super hard abrasive bonded abrasive tool.The former uses the conventional abrasive materials such as corundum and carborundum, and the latter makes with the super hard abrasive such as diamond and cubic boron nitride.In addition, also have some special kinds, as sintered fused alumina abrasive tool etc.

Conventional abrasive material bonded abrasive tool is, by bonding agent, conventional abrasive material is consolidated into definite shape, and has the grinding tool of some strength.Generally be made up of abrasive material, bonding agent and pore, this three part is often called the three elements of bonded abrasive tool.Abrasive material plays shear action in grinding tool.Bonding agent is the material that loose abrasive material is consolidated into grinding tool, has inorganic and organic two classes.Inorganic bonding agent has pottery, magnesia and sodium metasilicate etc.; Organically there are resin, rubber and shellac etc.Wherein the most frequently used is pottery, resin and gum cement.Pore plays and holds bits and chip removal effect abrasive dust in the time of grinding, and can hold cooling fluid, contributes to the dissipation of grinding heat.For meeting some special processing request, in pore, can also flood some filler, as Sulfur and paraffin etc., to improve the serviceability of grinding tool.

Current grinding tool is to be all fixing shape by one-shot forming, and then by fixed or sinter molding.Once but after grinding tool moulding, so because its needs that are adapted to use need certain intensity, just very difficult in the time that it changes its shape in order to adapt to different grinding need for environments; And when being ground to a certain degree, a part of grinding tool is when serious wear and another part still can use, due to its excision forming difficulty, so remainder can only abandon.

Utility model content

The technical problem that the utility model solves is to provide a kind of and consists of the stacked of grinding unit based on the stacked emery wheel of grinding unit, and easy to process, grinding performance is good.

The utility model is to be achieved through the following technical solutions:

Based on the stacked emery wheel of grinding unit, comprise that surface is consolidated with the base-material of grinding unit, between grinding unit, leave gap, multilayer base-material is to show supine mode around stack, and the grinding unit upper-lower position of adjacent two layers base-material mutually staggers or intersects; The base-material back side of inner side forms through hole.

Described grinding unit with the formal distribution of array on base-material.

Described grinding unit is strip and is evenly distributed on base-material, and the grinding unit upper-lower position of adjacent two layers base-material is mutually vertical.

Described adjacent two layers base-material is also by the fixed connection of binding agent.

In described base-material, be also interspersed with dowel.

Described base-material is band shape or the strip material that paper base material or cloth-based material are made.

Compared with prior art, the utlity model has following useful technique effect:

The utility model provide based on the stacked emery wheel of grinding unit, binder layer by multiple-level surface being consolidated with to grinding unit around stack after fixed moulding, so just the flexible material that easily changes shape making is passed through to stack, fixed rear formation grinding tool, pressed compact while having avoided so existing emery wheel, dry and roasting, and because each grinding unit is separated and arranged, so just can be relatively easy the emery wheel that multiple grinding requires is set; And the setting in gap had both been conducive to the heat radiation of grinding process between grinding unit, can also be easily by the abrasive dust producing in grinding process.

The utility model provide based on the stacked emery wheel of grinding unit, can also change flexibly according to grinding situation the overlapped way of grinding unit, such as the grinding unit upper-lower position of adjacent two layers base-material mutually stagger or intersect; And for the higher heavy duty grinding wheel of burden requirement, can also be in base-material also intert dowel.
