Abstract
The utility model relates to a disc saw blade, which belongs to the technical field of mechanical cut. The utility model is designed to bear larger load. The utility model is a disc-shaped sheet material, wherein, the edge of the sheet material is provided with saw teeth, and the center of the sheet material is provided with a mounting hole. The utility model is characterized in that the shape of the utility model is a rotating curved surface; the edge of the rotating curved surface is arranged in a plane 2 which is perpendicular to a core line 1, and the distance between the curved surface and the plane 2 is larger by that the curved surface closes to the center, namely the utility model forms a pan shape, the edge of the pan is more shallow, and the distance between the edge and the center part is deep. By tested, the thickness of the saw blade can be reduced half. The utility model has the advantages that the wood moulded rate and the work efficiency is high, and the power consumption and the diamond bit tool consumption are low, As for the rebuilding of stone equipment, the profit per day can be increased to near 3000 yuan from 200 yuan.
Description
The utility model belongs to the machine cut technical field, refers more particularly to the saw blade of circular saw.
Existing circular saw bit is that its edge is set to the discoidal flat board that sawtooth, its center have installing hole.When high speed rotary carried out machining, the reaction force that is subjected to being cut material that each part at its edge replaces made that each of circular saw bit is local to be produced trace distortion alternately and rock, and destruction such as easily cracked.In this way, circular saw bit will actual required be done thickly than its, and live load just can not reach or near the limit of the ability of material own.
The purpose of this utility model provides a kind of circular saw bit, and when high speed rotary carried out machining, it can not rock, and with regard to the circular saw bit of same material, stack pile, it can bear bigger live load.
The purpose of this utility model is achieved in that
A kind of circular saw bit is that its edge has sawtooth, its center that the discoidal sheet material of installing hole is arranged, and it is characterized in that: its shape is the single-revolution curved surface, and its edge is positioned at a plane perpendicular to heart yearn, and near more center is far away more from the distance on this plane.That is to say: its shape is a pot shape, and the edge of this pot is more shallow, and is gradually dark to central part.
Through test, as above the circular saw bit of structure can bear high live load and arranged high service life when being used for sawmilling material and stone material.And (under common situation) saw blade thickness can reduce half, improves volume recovery 20%; Tangent plane is smooth, and qualification rate is bordering on 100%; Work efficiency is original 3 times; The specific yield power consumption is original 1/3, and the consumption of diamond segment is original 1/2; For the transformation of certain stone material equipment, make its day profit be increased to nearly 3000 yuan by 200 yuan.Through observing, when high speed rotary, it has become a planar shaped by original pot deformation, even also do not rock when work, this may be that the comprehensive function of centrifugal force and deformation elastic force makes so.And some above-mentioned remarkable effects may be because this " does not rock " and is brought.
Introduce the embodiment of described circular saw bit below in conjunction with accompanying drawing:
Fig. 1 is the schematic diagram that should plant circular saw bit.
Fig. 2 is the scheme of installation that should plant circular saw bit, and its line of vision is for overlooking.
As shown in the figure, a kind of circular saw bit 9 is that its edge has sawtooth, its center that the discoidal sheet material of installing hole is arranged, and it is characterized in that: its shape is the single-revolution curved surface, its edge is positioned at a plane 2 perpendicular to heart yearn 1, and near more center is far away more from the distance on this plane 2.
That is to say: its shape is a pot shape, and the edge of this pot is more shallow, and is gradually dark to central part.
The center of this circular saw bit 9 to the ratio (being aspect ratio) of the distance on plane 2 and (a kind of circular saw bit 9) diameter between 1/250 to 1/10.Especially between 1/100 to 1/50.
The mounting structure of following this kind circular saw bit of introducing is for making its ancillary method in when work " not rocking ":
As shown in Figure 2, the installation of circular saw bit 9 on its driving shaft 11, it is sandwiched between the reducing ladder 111 and packing ring 112 of driving shaft 11, and nut 113 is threaded, is locked on the packing ring 112 with driving shaft 11 row.The fastening force of the structure of this set more existing (at the periphery of the packing ring that goes in ring with 6-8 bolted) is balance more.
As shown in Figure 2, this kind circular saw bit 9 is installed on its driving shaft 11, at the two ends of one bar diameter (generally being a horizontal diameter), is installed with a pair of auxiliary stable folder 18 respectively.Auxiliary stable folder 18 comprises a female cylindrical shell 181 that is packed on the frame; Fill in wooden cylinder 182 in the cylindrical shell 181; The screw rod 183 that is fixed with handwheel 184 on it matches with the internal thread of cylindrical shell 181.Rotate handwheel 184 and wooden cylinder 182 outwards ejecting progressively so that the shape of circular saw bit 9 is assisted restriction, can be played stable circular saw bit 9.
Claims (3)
1. circular saw bit, be that its edge has sawtooth, its center that the discoidal sheet material of installing hole is arranged, it is characterized in that: its shape is the single-revolution curved surface, and its edge is positioned at a plane perpendicular to heart yearn (1) (2), and near more center is far away more from the distance of this plane (2).
2. circular saw bit according to claim 1 is characterized in that: aspect ratio is between 1/250 to 1/10.
