Abstract
The utility model discloses a novel multi -disc saw gasket for, including discoid gasket main part, be equipped with the main shaft fixed orifices on the centre of a circle of gasket main part, two terminal surfaces of gasket main part on all be equipped with to the sunken radiating groove in inboard, still be equipped with the round arc groove on the outside circumference of gasket main part, the utility model discloses mill a radiating groove on two terminal surfaces of gasket, it is rotatory with the help of the high speed of axle for circulating in the radiating groove of air between gasket and body, taking away the heat, prevent the emergence of heat altered shape, special radiating groove structure still can keep fitting the tensile stress, on the other hand cuts the effect that the material played direction and relatively fixed through the arc groove that radial face milling goes out to the quilt, prevents that material and saw bit from taking place friction, adoption the utility model discloses, the comparable normal average value of life of saw bit exceeds 20%, corresponding improvement production efficiency about 20%.
Description
Technical field
The utility model relates to multiple blade saw saw pad.
Background technology
Solid wood multiple blade saw saw main shaft is generally provided with the saw blade that 3-30 sheet does not wait; wherein 80% is ultrathin saw bit; high all especially to the requirement of saw blade and whole saw cutting system during sawing; if wherein certain a slice generation overheating deforming; whole group of saw blade then can be caused to shut down; change spended time very long, reduce Client Work efficiency.
Through practice and observation for a long time, find that the main cause that saw blade heating is out of shape is following 2 points: on the one hand owing to continuing to use full entity pad in industry always, its structure as shown in Figure 1, like this when High Rotation Speed cuts, the heat in metal cutting produced progressively is assembled by cutting point and is accumulated in pad, heat energy cannot distribute in time, the thermal stress to saw plate can be produced, in addition very crucial a bit: saw blade is when making, consider the dynamic stability of saw blade, can to the prefabricated tensioned stress of saw blade, and tensioned stress position is also in pads placement, the dynamic stability of negative thermal stress to saw blade plays lethal affect, the distortion of saw blade can be aggravated like this.
On the other hand because cut next material can move through the longitudinal end of pad, and pad does not have guide frame, cut next material continues along with feeding, material is run-off the straight likely, its state as shown in Figure 2, material and blade body can be caused like this to rub, have a negative impact.
Utility model content
The utility model object is to overcome above-mentioned the deficiencies in the prior art, provides a kind of Novel multichip rip saw saw pad, can effectively prevent saw blade overheating deforming, improves the service life of saw blade, reduces multiple blade saw saw shutdown maintenance number of times, to improve working (machining) efficiency.
The technical solution of the utility model is: a kind of Novel multichip rip saw saw pad, comprise the gasket body of plate-like, the center of circle of gasket body is provided with main shaft fixing hole, two end faces of described gasket body are all provided with the radiating groove caved in the inside, the outer circumference of gasket body are also provided with a circle arc groove.
Consider the dynamic stability of saw blade, need the prefabricated tensioned stress of saw blade, it is the auxiliary heat dissipation groove that the center of circle is arranged at the cannelure of main shaft fixing hole periphery and Duo Gen and arranges along gasket body radial direction that the radiating groove at described gasket body two ends all comprises with gasket body, one end of described auxiliary heat dissipation groove is communicated with main shaft fixing hole, the other end of auxiliary heat dissipation groove and the edge of gasket body keep certain gap, middle part and the cannelure of auxiliary heat dissipation groove are communicated as one, such structure both can ensure the thermal diffusivity of saw blade, can retain again the tensioned stress of saw blade.
Described auxiliary heat dissipation groove has three, and annular array is on the end face of gasket body centered by the center of circle of gasket body for three auxiliary heat dissipation grooves, and the auxiliary heat dissipation groove at two ends is staggeredly set.
Described arc groove is arranged at the middle part of gasket body outer circumference, keeps certain gap between the top of arc groove and the edge of gasket body outer circumference.
The beneficial effects of the utility model are: the utility model mills out radiating groove on two end faces of pad, by the High Rotation Speed of axle, make to circulate in the radiating groove of air between pad and body, take away heat, prevent the generation of thermal deformation, special radiating groove structure still can keep tensioned stress; The arc groove milled out by longitudinal end on the other hand plays guiding and relatively-stationary effect to cut timber material, prevent material and saw blade from rubbing, adopt the utility model, the comparable normal average value in service life of saw blade exceeds 20%, correspondingly enhances productivity about 20%.
