Description

Band saw

The utility model relates to woodworking machinery, the band saw of the saw processing that is used for timber of more clearly saying so.

Present band saw is mostly by base, frame, upper case, lower case, workbench and bearing thereof, motor, upper belt-wheel, bands for band strainer, the guidance set up and down etc. of belt wheel, driving-belt strainer, bands for band, driving-belt, bands for band constitutes down.Wherein the method for center distance of belt wheel up and down of adjusting is adopted in the tensioning of bands for band mostly, and this method or use tension wheel structure is more loaded down with trivial details during adjustment, time-consuming, not have the effect of unsteady automatically adjustment tensioning.In addition, when bands for band because up and down during the beat sideslip of belt wheel, also can only be with the simpler and cruder loaded down with trivial details adjustment method adjustment of belt wheel up and down, quite time-consuming, and will rely on the experience of adjusting the worker.Because of there not being special adjusting deviation device, in addition cause the bands for band landing, cause parts, workpiece damages and personal injury.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, and a kind of strainer with improved bands for band is provided, and is simple during adjustment, save time, efficiently, and the corrective action of floating is automatically arranged; And having an adjusting deviation device of upper belt-wheel, tuningout is simple, can prevent that bands for band sideslip even landing from causing damages or the band saw of injury.

In order to achieve the above object, the utility model band saw by base, be installed in base on frame, rack-mounted upper case and lower case, be installed in workbench and bearing and motor and control circuit thereof on the lower case, be installed in upper belt-wheel and bands for band strainer on the upper case, be installed in following belt wheel on the lower case, be installed in the bands for band on the belt wheel up and down and be installed in down belt wheel and motor between transmission mechanism constitute.The bands for band strainer by be fixed on have on the upper case vertical gathering sill about two guide plates, be installed between the guide plate of the left and right sides upper end with holes about the U-shaped frame of band concentric holes, be installed in the transverse axis in the gathering sill of the concentric holes of U-shaped frame and left and right sides guide plate, be fixed on the axle block on the transverse axis, be installed in upper whorl axial and upper belt-wheel on the axle block, be fixed on the upper case bearing with vertical hole, be installed in the vertical hole of bearing and the mandrel of upper end band boss, be sleeved on the dish spring on the mandrel, on mandrel and the nut between the U-shaped frame, passing the adjusting screw(rod) that the hole of U-shaped frame upper end is screwed in the nut constitutes.

The adjusting deviation device of upper belt-wheel also is installed on the upper case.It by be fixed on hold-down nut on the upper case, end band screw rod be installed in the hold-down nut and withstand on the adjustment button of axle block lower end, the locking button that is installed in the screw rod of adjusting button is constituted.

After bands for band was loose, with adjusting screw(rod) dextrorotation, it just was screwed into along the hole of U-shaped frame upper end and the screw of nut, withstood on the boss upper end of mandrel.And then lean on boss that the dish spring is compressed.Along with the increase that is screwed into the degree of depth, the compression of dish spring is more and more tighter, and its compressive tension is increasing.When dish spring tension force during greater than the tension force of bands for band, the dish spring will move up together with nut, U-shaped frame, transverse axis, axle block, upper whorl axial and upper belt-wheel by the boss jack-up adjusting screw(rod) of mandrel, with the bands for band tensioning.Under the normal condition, floating of dish spring can be adjusted its tension force automatically, makes it to keep dynamic balance with the tension force of bands for band, plays the effect of automatic adjustment bands for band tensioning in certain scope.Its adjustment is simple, quick, laborsaving.During adjustment, transverse axis moves up and down in the vertical gathering sill of left and right sides guide plate, and guiding is good.The U-shaped frame then moves up and down between the guide plate of the left and right sides.

When upper belt-wheel beat bands for band sideslip, turn the adjustment button, its screw rod just is screwed into or the hold-down nut of back-outing, the screw rod end is just moved axle block lower end jack-up or fall to the lower right beat to the upper left side and moves, and then drive upper whorl axial and upper belt-wheel to upper left side or lower right beat, play the effect of adjusting the upper belt-wheel beat.This tuningout mode saves labor, and is simple.After being transferred to the appropriate location, tightening locking button positioning and locking again and get final product.

Task of the present utility model comes to this and finishes.

The adjustment of the utility model strainer is simple, save time, laborsaving, and the function of the adjustment of floating is automatically arranged.It also is equipped with the adjusting deviation device of upper belt-wheel, and is simple equally, laborsaving during tuningout, save time, quite safe.It can be widely used in timber, woodwork, the processing of half-finished saw.

The utility model will be further described below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is the schematic diagram of the adjusting deviation device of the bands for band strainer of embodiment 1 and upper belt-wheel, that is the top cutaway view of embodiment 1.

Fig. 2 is the left view of Fig. 1.

Illustrated in figures 1 and 2, the bands for band strainer of embodiment 1 by on the base plate that is fixed on upper case 14 and have vertical gathering sill 15 about two guide plates 12, U-shaped frame 6, transverse axis 7, axle block 11, upper whorl axial 8 and upper belt-wheels 13, be fixed on the bearing 5 on the base plate of upper case 14, mandrel 3, dish spring 4, nut 2 and the adjusting screw(rod) 1 of band boss constitutes.The adjusting deviation device of upper belt-wheel also is installed on the upper case 14.It by be fixed on hold-down nut 16, the end band screw rod 17 on the upper case 14 and withstand on axle block 11 lower ends adjustment button 9, locking button 10 constitute.

During the tensioning adjustment of the bands for band of embodiment 1, the beat adjustment of upper belt-wheel saw simple, laborsaving, that save time, can be widely used in Wood material wood product are processed.
