Abstract
The utility model discloses a scraper type saw with multiple blades, which comprises cutting bits (2). The cutting bits (2) are arranged on a saw blade base (1) at intervals, a chip pocket (7) is formed between each two adjacent cutting bits (2), at least one scraper (3) is fixedly mounted on the saw blade base (1), and at least one expansion groove (6) and at least two radiating grooves (5) are disposed on the saw blade base (1). The scraper type saw with multiple blades has the advantages that heat generated during cutting is low, and the scraper type saw with multiple blades is good in self-cooling effect, long in service life and high in cutting quality.
Description
Technical field
The utility model relates to saw blade, is specifically related to a kind of scraper type multiple blade saw.
Background technology
The multi-disc sawing machine has obtained using widely because of its working (machining) efficiency is high.Present stage, the saw blade that uses of multi-disc sawing machine was the rip cutting saw blade of routine; This aborning saw blade chip removal difficulty, extruding, friction generates high temperature are considered in the saw blade of rotation and ever-increasing processing to be worth doing at a high speed, for reducing temperature; Use cooling fluid to cool off, this has strengthened the chip removal difficulty again.Under this vicious circle, the saw blade easy deformation, thus influence the saw blade machining accuracy, shorten saw life.Under hot environment, the sawn timber size also can change, and influences the dimensional accuracy of finished product.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, provides a kind of chip removal effective, the scraper type multiple blade saw that the life-span is long.
The purpose of the utility model realizes through following technical scheme:
The scraper type multiple blade saw, it comprises that the interval is arranged on the cutter head 2 on the saw bit matrix 1, constitutes chip pocket 7 between the adjacent cutter head 2, on saw bit matrix 1, fixedly mounts a scraper 3 at least, is provided with an expansion slot 6 at least.
Extend and formation scraper groove 4 to saw bit matrix 1 center the bottom of at least one chip pocket 7; The sidewall of scraper groove 4 is provided with scraper 3; Have at least the bottom of a chip pocket 7 to extend and formation expansion slot 6 to saw bit matrix 1 center, expansion slot 6 is the structure of outer narrow inner width.
On saw bit matrix 1, be provided with two radiating grooves 5 at least, radiating groove 5 is the streamlined through hole.
Can find out that through top narration the advantage of the utility model is:
1. design the scraper groove on the saw bit matrix, and scraper has been installed, can reduce the friction between saw bit matrix and the sawn timber more effectively, suppressed the generation of work cutting heat from root;
2. be provided with streamlined radiating groove, when saw blade rotated at a high speed, the air-flow that forms between the radiating groove can reduce saw bit matrix and the fricative heat of sawn timber to the full extent, thereby reaches self cooling effect;
3. saw bit matrix is provided with expansion slot, can effectively discharge saw blade when rotating at a high speed because of receiving the pressure of great centrifugal force in the gathering of saw blade outer rim place, avoided producing thus the adverse consequences of saw blade " swing ".
Above effect can effectively improve the life-span and the cutting quality of saw blade.
