Abstract

A dustless rock wool cutting tool is characterized by comprising a circular ring-shaped cutter, a circle of annular blade is arranged at the outer edge of the cutter, the section of the annular blade is in a triangular shape employing a tool nose as a point angle, the thickness of the cutter ranges from 3mm to 8mm, the outside diameter of the tool nose ranges from 300mm to 650mm, the width of the blade ranges from 25mm to 50mm, and the angle alpha of the tool nose ranges from 3 degrees to 18 degrees. The dustless rock wool cutting tool commonly made of hard alloy steel has the advantages that dust quantity in rock wool board production is extremely small so that dust collecting equipment is omitted, the cutting output of the tool is small, rock wool board yield is high, the influence of dust remaining on product surfaces on product quality caused by large dust quantity and poor dust collecting effect is avoided, and the labor intensity of workers in dust cleaning is reduced.

Description

The dustless cutting tool of a kind of rock wool

Technical field

The utility model relates to the rock cotton board production equipment, relates to the dustless cutting tool of a kind of rock wool specifically.

Background technology

Rock wool is the material of a kind of insulation, heat insulation, sound insulation, because it has superior energy-conservation, fire prevention, sound insulation, environmental protection, the "dead" energy of no burn into, so be widely used in the occasions such as insulation, fire prevention of industry and building etc.The cutting tool (referring to Fig. 1) of rock wool production equipment outfit at present, what generally adopt is the saw blade 2 that has sawtooth 1, because the thickness of sawtooth 1 is thicker, the Dust Capacity that produces during cutting is very big, not only very high to the requirement of dust collection device, energy consumption of gathering dust and working strength of workers are also very big.

Summary of the invention

At above-mentioned situation, the utility model provides a kind of rock wool dustless cutting tool, to solve a large amount of dust pollutions that produce when rock wool is cut in the prior art, the problem that reduces gather dust energy consumption and labor strength.

To achieve these goals, the technical solution of the utility model is as follows:

The dustless cutting tool of a kind of rock wool is characterized in that, comprises cutterhead, and described cutterhead is an annular, and the cutterhead outer rim is provided with a circle circular blade, and the cross section of described circular blade is drift angle shape triangular in shape with the point of a knife.

Further, described cutterhead thickness is 3 ~ 8mm.

Further, the outside diameter that surrounds of described point of a knife is 300 ~ 650mm.

Further, the width of described blade is 25 ~ 50mm.

Further, described point of a knife angle is 3 ~ 18 °.

The beneficial effects of the utility model are that the Dust Capacity during the production rock cotton board is few, no airborne dust, needn't use dust collection device; The Tool in Cutting amount is little, rock cotton board yield rate height; Avoided owing to Dust Capacity is big, the dust collection effect difference causes that dust remains in product surface and influences product quality; Reduced the labor strength of cleaning dust.

Description of drawings

Fig. 1 has the structural representation of the cutting tool of sawtooth for prior art.

Fig. 2 is the front view of the dustless cutting tool of a kind of rock wool of the utility model.

Fig. 3 is the side-looking broken section enlarged drawing of the dustless cutting tool of a kind of rock wool of the utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 2, Fig. 3, the dustless cutting tool of a kind of rock wool is characterized in that, comprises cutterhead 300, and described cutterhead 300 is an annular, and cutterhead 300 outer rims are provided with a circle circular blade 400, and the cross section of described circular blade 400 is a drift angle shape triangular in shape with point of a knife 410.Described cutterhead 300 thickness W are 3 ~ 8mm, and accepted value is W=5.5mm.The outside diameter D of described point of a knife 410 is 300 ~ 650mm, and accepted value is D=450mm.The width H of described blade is 25 ~ 50mm, and accepted value is H=35mm.Described point of a knife angle [alpha] is 3 ~ 18 °, and accepted value is α=11 °.

The common used material that the utility model adopts is a hard alloy steel.When cutter cutting rock wool, the rotating speed of cutter is too high can to wear and tear by the aggravation blade, and produces a large amount of heats, causes the heat radiation difficulty to cause blade and blade distortion; The rotating speed of cutter is crossed slowly can make the cut surface out-of-flatness.So cutter should be provided with a suitable rotating speed, the linear velocity that makes blade is 3 ~ 10 times of cutting speed of product; Cutting speed as fruit product changes, and the cutter rotating speed is changed thereupon synchronously, so that sharp blade entirely cuts off rock wool, both can guarantee the effect of cutting, and can prolong the service life of cutter again.

When the utility model was produced in rock cotton board, cutting output was little, had improved yield rate; Dust Capacity is few, does not need dust collection device, has reduced power consumption; Avoided owing to Dust Capacity is big, the dust collection effect difference causes that dust remains in product surface and influences product quality; Reduced the labor strength of cleaning dust.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
