Abstract

The utility model relates to a planning type circular saw blade, which is an improvement to the prior circular saw blade. The utility model consists of a disk body, a fixing hole and a plurality of saw teeth; wherein the thickness of the disk body is smaller than the thickness of saw teeth; the thickness of the front saw teeth and the rear teeth is the same, which locates at the same plane; and the blade openings of the front saw teeth and the rear teeth are swallow tailed, the saw teeth of which are alternately arranged on the circumference of the disk body. The utility model is simple in structure, convenient to be used, integrates sawing and polishing into one entity, time saving, labor saving, energy saving, favorable to the nation and people and greatly saves limber.

Description

The type of scraping circular saw bench

(1) technical field

The utility model relates to a kind of type of scraping circular saw bench that is used for timber processing, is the big property the improved circular saw bench to existing circular saw bench.

(2) background technology

Existing circular saw bench is by disk body, fixing hole and sawtooth constitute, sawtooth left, stagger in right both sides, not not in one plane, sawtooth cutting edge face is identical, and sawtooth is identical with disk body thickness, and this circular saw bench in use can only cut raw material (as timber), its saw kerf face is coarse, can not be directly used in the making product, need with plane the saw kerf face to be scraped in addition again, it is not only time-consuming, take the energy, also wasted raw material in large quantities, particularly waste is serious in timber processing, and this China to the timber shortage is disadvantageous, how effectively saving timber is a very serious problem, and the chuck body phenomenon in use also often appears, and influencing operate as normal, efficient is low.

(3) the utility model content

At the problems referred to above, the type of the scraping circular saw bench that the purpose of the utility model is used with regard to providing a kind of novel converted timber, to solve the problem of timber processing trouble and waste effectively, the utility model includes disk body, fixing hole and sawtooth constitute, sawtooth thickness is greater than disk body thickness, sawtooth faces mutually and arranges about the sawtooth cutting edge replaces at grade, and front and back constitute the dove-tail form cutting edge, it is simple in structure, easy to use, the loaded down with trivial details problem of former converted timber is solved, the collection log cuts, scrape and once finish, the saving of labor, power saving, save time, save the waste problem in timber and the processing greatly, benefit the nation and the people.

(4) description of drawings

Fig. 1 is structural front view of the present utility model (dotted line is the same saw tooth of saving).

Fig. 2 is side cross-sectional view of the present utility model (amplification).

Fig. 3 is vertical view of the present utility model (amplification).

(5) specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is specified.

Provide by Fig. 1, the utility model is to be made of disk body, center fixation hole and sawtooth, the thickness of disk body 1 is less than the thickness of sawtooth 3, sawtooth 4, sawtooth 3 is identical with sawtooth 4 thickness, and at grade, right front face has cutting edge 5 on the sawtooth 3, and left front face has cutting edge 5 on the sawtooth 4, cutting edge 5 front and back on the sawtooth 3,4 are dovetail shaped, the sawtooth 3 of right side cutting edge is arranged and have the sawtooth 4 of left side cutting edge to be arranged alternately on the circumferential edge of disk body 1; In order to guarantee result of use, sawtooth 3,4 tops become inclined-plane (seeing shown in Figure 2), and the inclined-plane of cutting edge 5 (seeing shown in Figure 3) triangular in shape, the thickness of sawtooth 3 generally should be about 2 times of disk body 1 thickness.The circular saw bench that with the diameter is 300mm is a side, and the center can be 25mm, the thick 1.6mm of disk body, the thick 2.8mm of sawtooth with the diameter of deciding hole 2.It uses with existing circular saw bench, only needs also can on center fixation hole 2 is contained in the line shaft of circular saw.During manufacturing, cutting edge is interchangeable on the sawtooth of front and back, just can as long as alternately arrange front and back.

By said structure as can be seen, the utility model since sawtooth thickness greater than disk body thickness, so overcome the easy nipped problem of former disk body, improved the speed of processing, saved the time, because cutting edge is divided right and left, sawtooth is in same plane, overcome the Burr Problem that sawtooth is not produced in a plane, the saw kerf face is smooth smooth, does not need to scrape separately again, has once finished two procedures that cut and scrape, save time, laborsaving, economize the energy, particularly saved the waste problem of timber in processing is scraped, through measuring and calculating on probation, timber utilization rate improves greatly, bring up to about 90% by traditional 80%, the annual hundred ten thousand stere timber of saving directly reduce several ten million yuan of economic losses, and are very good through trial effect, be popular, it is applied and must make creative contribution for timber processing.

Claims

1, a kind of type circular saw bench of scraping, including disk body, center fixation hole and sawtooth constitutes, it is characterized in that the thickness of the thickness of disk body (1) less than sawtooth (3), sawtooth (4), sawtooth (3) is identical with sawtooth (4) thickness, and at grade, the last right front face of sawtooth (3) has cutting edge (5), the last left front face of sawtooth (4) has cutting edge (5), be dovetail shaped before and after the cutting edge (5) on sawtooth (3), (4), the sawtooth (3) that right side cutting edge arranged with have about the sawtooth (4) of face cutting edge be arranged alternately on the periphery of disk body (1).

2, the type circular saw bench of scraping according to claim 1 is characterized in that sawtooth (3), (4) top become the inclined-plane, and the inclined-plane of cutting edge (5) is triangular in shape.
