Abstract

The invention discloses a double-molding density resin cutting sheet which comprises a main body and process blocks, wherein the main body and the process blocks are homogeneous and integral. The main body is in a shape of a wafer, molding density is 2.2-2.4g/cm<3> after mould pressing, 16-35 process blocks inclined in the same direction are evenly pressed on the periphery of the upper edge of the end face of the main body, and molding density of the process blocks after mould pressing is 1.8-2.0g/cm<3>. Planes of the process blocks are in a shape of sole, the big ends face outwards, and the small ends face inwards, the process blocks inclined in the same direction are arranged on the end face of the main body, the process blocks are bent rightwards and arranged in sequence on the front side of the main body, and the process blocks are bent leftwards and arranged in sequence on the reverse side of the main body. The double-molding density resin cutting sheet is sharp, large in cutting ratio and small in current drain, saves time, improves working efficiency obviously, and reduces use cost of users obviously.

Description

Two compact density resin cutting slices

Technical field

The present invention relates to a kind of disc wheel, specifically, the present invention relates to a kind of resin cutting slice with two compact densities.

Background technology

The resin cutting slice that is used for the cutting metal member is a kind of disc wheel, belongs to the easy-consumed goods of low value, and market demand is very big.At present, the commercial resin cutting blade brand of supplying on the market has many kinds, if only have two big types by moulding density region branch, promptly high compact density and low compact density resin cutting slice.The resin cutting slice that compact density is different can satisfy the demand that the user cuts different metal materials.The resin cutting slice dense structure of high compact density, quality are hard partially, intensity is high; But gas permeability is poor; Cause cut surface and produced high temperature by the otch of cut spare, the broken last metal that is downcut is softening under high temperature action to be prone to adhere on the cutting blade working face, further thus passivation cutting blade; Continue on for cutting operation except that the efficient difference, also be prone to the burn workpiece.The resin cutting slice of low compact density is organized loose relatively, and good permeability helps cutting.But the close resin cutting slice consumption of low moulding is bigger, and service life is shorter, and this kind situation must increase customer using cost.Generally speaking, the single compact density resin cutting slice of prior art manufacturing can be used in production to the greatest extent, but the problem that exists in actual the use also clearly, and combination property does not satisfy user's instructions for use.

Summary of the invention

The present invention is primarily aimed at the deficiency of prior art products function singleness, proposes a kind of simple in structure, easy to manufacture, cutting efficiency is high, cut ratio is big two compact density resin cutting slices.

The present invention realizes technical goal through following technical proposals.

Two compact density resin cutting slices, it comprises the main body and the technique block of homogeneity one.Its improvements are: said main body is the disk shape, and mold pressing aftershaping density is 2.2～2.4g/cm ³, periphery is all suppressed 16～35 one along tilting technique block in main body end face upper edge, and the technique block compact density of mold pressing is 1.8～2.0g/cm ³

Technique block flat shape in the said structure is a sole-shaped, and with stub end outwardly, little head end is inwardly one along tilting on the main body end face, every technique block area of plane 60mm ²～200mm ²Technique block is the curved order of dextrorotation arranges in the main body front, and reverse side is left-handed curved order and arranges.

As further improvement project, said technique block flat shape is fan-shaped, and with stub end outwardly, little head end is inwardly one along tilting on the main body end face, every technique block area of plane 60mm ²～200mm ²Technique block is the curved order of dextrorotation arranges in the main body front, and reverse side is left-handed curved order and arranges.

The present invention compared with prior art has following good effect:

1, the resin cutting slice of compression moulding is organized by two kinds of different compact densities that five equilibrium is alternate to be constituted, high, the good hand touch of hard soft alternately cutting efficiency;

2, at the tissue of the alternate two kinds of different compact densities of the first-class branch of resin cutting slice circumference, constitute the structure that has complementary functions, both reduced the own loss of technique block, ventilative environment when having improved the main body cutting again reduces the cutting heat greatly;

3, two compact density resin cutting slices are sharp, and cut ratio is big, and current drain is few, save time, and both significantly improved work efficiency, also significantly reduce customer using cost.

Description of drawings

Fig. 1 is a structural profile sketch map of the present invention.

Fig. 2 is Fig. 1 left view, and this face is positive.

Fig. 3 is Fig. 1 right view, and this face is a reverse side.

The specific embodiment

Based on accompanying drawing and combine embodiment, the present invention is described further below.

Two compact density resin cutting slices shown in Figure 1, it comprises the main body 1 and technique block 2 of homogeneity one.Main body 1 is the disk shape, and mold pressing aftershaping density is 2.2～2.4g/cm ³, all suppress 16～35 one along tilting technique block 2 at main body 1 end face upper edge periphery, technique block 2 compact densities of mold pressing are 1.8～2.0g/cm ³The two compact density resin cutting slice specifications of present embodiment are 12.5*1*22.2, on main body 1 end face, all suppress 24 road technique block 2.Technique block 2 flat shapes are sole-shaped, and with stub end outwardly, little head end is inwardly one along tilting on main body 1 end face, every technique block 2 area of plane 95mm ²The technique block seen from the main body 1 front 2 curved orders of dextrorotation that are as shown in Figure 2 are arranged, and the technique block seen from main body 1 reverse side 2 is as shown in Figure 3 to be left-handed curved order and to arrange.

In order to verify cutting performance of the present invention, to get 10 same specification products of producing with prior art and do the performance comparison test, test is carried out under unified condition; That is: product specification is 12.5*1*22.2; Weigh 25 grams, cutting material is 304 stainless steel bars of φ 10mm, and the electric tool brand is BOSCH, power 750W, rotating speed 11000r/min; Manual time-keeping, the test data contrast table is attached.

10 example cutting test data contrast tables

Annotate: 1, A represents the prior art compact density at 2.2～2.4g/cm in the table ³Resin cutting slice;

B represents the prior art compact density at 1.8～2.0g/cm in the table ³Resin cutting slice;

C represents the two compact density resin cutting slices of Ben Fa invention in the table.

The ratio of the metal total sectional area of 2, cut ratio---excision and the end area of abrasion of grinding wheel.

Can know that from above-mentioned test data when the two compact density resin cutting slices of the present invention cut, main performance index was superior to prior art products, has both significantly improved work efficiency, also reduces customer using cost.
