Description

Combined band-sawing machine

The relevant a kind of band sawing machine of the present invention refers to a kind ofly drive saw band cutting timber simultaneously or stone material is the band sawing machine of a plurality of sheet materials with a plurality of belt wheels especially.

The timber band sawing machine of prior art, its up and down belt wheel be installed on respectively on the power transmission shaft of lower body, a saw band is surrounded on about this on belt wheel, upper belt-wheel can be made Height Adjustment to do the tightness adjustment of saw band, when saw band cutting timber, one time a slice ground is sheet material with the timber sawing in regular turn; The cutting operation output of this timber band sawing machine is restricted, and its support and body system are remake further and are processed into by iron casting, and cost is higher; Stone material cutting industry part utilizes this timber saw band equipment replacement to be the diamond saw band, as the cutting stone material purposes, and also only can sawing a slice stone material when operation.

In the multiple-piece makita 4100NH of prior art, a kind of multiple-piece diamond dragsaw is when cutting marble, the saw plate moves back and forth with saw total number ton weight, usually stroke is 40 to 60 centimetres, if once in each reciprocating stroke work, usually per minute can be reciprocal 70 to 120 times, and its vibration frequency height and amplitude are big, and noise is high again.

A kind of multiple-piece steel sand dragsaw, when cutting granite, its vibration frequency and amplitude and noise are big more than the diamond dragsaw.

A kind of multiple-piece diamond circular sawing machine, when cutting stone material, its main motor horsepower is usually between 100 to 300 horsepowers, diamond saw blade number is between 10 to 30, the diamond tooth width is between 8.0 to 9.0 millimeters, diamond sawtooth cutting speed is between 25 to 50 meters of per seconds, and the noise and vibration that it produced is more or less the same with the diamond dragsaw.

The noise that the cutting machine of prior art is produced when cutting stone material, vibration etc., mainly from the equipment of cutting machine, it is when driving saw band or saw blade and contact with stone material, because of the precision deficiency of transmission and interlock equipment room, and the absorbing equipment of outer rim is also not enough, makes noise to reduce; The too high formed vibration of amplitude for the cutting tool of diamond sawtooth, also certainly will easily produce loss, improves the cost of cutting stone material.

The present invention's main purpose is to provide the band sawing machine of a kind of a plurality of timber of sawing simultaneously or masonry slab.
