Abstract

The utility model relates to a non-chip-sticking emery sanding grinding roller for a sander, which comprises a roller body (1). The non-chip-sticking emery sanding grinding roller is characterized in that a plurality rows of burrs (2) are arranged on the surface of the roller body, adjacent rows of burrs (2) are staggered in arrangement, and the surfaces of the both the roller body (1) and the burrs (2) are plated with emery. The non-chip-sticking emery sanding grinding roller is easy in chip discharging, evenness of workpieces to be machined is equal, and carbonization and sticking in the prior art are avoided.

Description

Not sticking bits diamond dust ramming grinding roller

Technical field

The utility model relates to the sander field, specifically, relates to a kind of not sticking bits diamond dust ramming grinding roller that is used on the sander.

Background technology

Sander commonly used at present is the sander in band abrasive band, drives rubber rollers by steel rider and rotates, and move under the drive of rubber rollers in the abrasive band, thereby workpiece is sand flat.Its major defect is:

1, power requires big.

2, the loss in abrasive band is big, needs frequent tape swapping, so the production cost height, and efficient is low.

3, the abrasive band wraps on the rubber rollers, and plate laterally has wave, and the workpiece flatness that sand comes out is low.

4, run the limit tearing tape easily, destroy the surface of rubber rollers.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sticking bits diamond dust ramming grinding roller is provided, and it can make and draw bits easily and improve the flatness of workpiece to be machined, and does not have " carbonization " phenomenon, also can " roll banding ".

The technical scheme that realizes above-mentioned purpose is: a kind of bits diamond dust ramming grinding roller that do not glue, comprise roll body, and the surface of roll body has many row's burrs, and adjacent row's burr dislocation arrangement, and the surface of roll body and burr all is coated with diamond dust.

The direction of burr becomes 10 ° ~ 70 ° angles with the axis direction of burr place circle.

The height of burr is 0.3 ~ 1.5mm.

The space width of adjacent burr is 2 ~ 6mm.

After adopting technique scheme, because the surface of roll body has many row's burrs, the surface of roll body and burr all is coated with diamond dust, the intensity of burr improves greatly, directly the grinder part goes out bits easily, so just need not to use the abrasive band, required power is just few, reduce cost, " roll banding " and " carbonization " phenomenon also can not occur, because and adjacent row's burr dislocation arrangement, from very close to each other between " on the whole " burr, thus fine through the workpiece flatness of processing.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1, 2, a kind of bits diamond dust ramming grinding roller that do not glue comprises roll body 1, and the surface of roll body has many row's burrs 2, and adjacent row's burr 2 dislocation arrangements, and the surface of roll body 1 and burr 2 all is coated with diamond dust.The direction of burr 2 becomes 10 ° ~ 70 ° angles with the axis direction of burr place circle.The height of burr 2 is 0.3 ~ 1.5mm.The space width of adjacent burr 2 is 2 ~ 6mm.

As shown in Figure 1, an end of roll body 1 is installed with flywheel 3.Adopt flywheel 3 can increase the inertia of sanding roller, reduce needed power.

The shape of burr 2 can be a ratchet shape as shown in Figure 2.The cross section of burr 2 can also be illustrated in figure 3 as trapezoidal or be illustrated in figure 4 as rectangle.

Sanding roller of the present utility model is the grinder part directly, need not to re-use the abrasive band, has avoided changing the trouble in abrasive band, has also reduced energy consumption simultaneously, has saved cost greatly.
