Description

Group saw band saw

Technical field

The invention belongs to wood processing machinery field, specifically refer to a kind of group saw band saw.

Background technology

The large processing timber of band sawing machine, woodwork or other part material materials is utilized to be a kind of important to cut processing Means, band sawing machine is typically main by saw frame, two belt wheels of above-below direction or left and right directions are fitted together hang up again saw blade by Driven by motor, auxiliary member has belt wheel spacing adjusting device, tensioning apparatus, operating platform and track sport car etc., and saw blade is an envelope The band-shaped steel band material processing closed, is rotated by driven by motor driving wheel and drives saw blade high-speed motion to utilize the saw blade tooth mouth of side right again Timber carries out Cutting indexes, and one action stroke may only process one piece of plate and cannot process many block, this shape Condition seems that effect has much room for improvement, and a kind of very worth exploitation of Novel band sawing machine that once can process polylith plate is attempted, and it is more Can meet people cuts processing needs.

Content of the invention

The purpose of the present invention is to provide the new technical scheme group saw band saw of a kind of band sawing machine, and it can be with one action Formation processes multi-sheets.

The technical scheme is that and be achieved in that, it comprises saw frame, saw frame panel, upper and lower belt wheel, head saw bar, in institute State outside the head saw bar sealing ring being directly connected to belt wheel, by multiple wheels that drive, stretching are taken turns, regulation wheel forms from inside to outside Device multiple between saw blade sealing ring；It is in position symmetrical up and down near upper and lower belt wheel at saw frame panel to be machined with respectively The rocking arm window of chute and sector, above-mentioned stretching wheel, the wheel shaft of regulation wheel are each passed through chute and rocking arm window and elevating lever, rocking arm Connecting, the left end of rocking arm is connected on saw frame panel by rocker arm shaft activity, and a drive then horizontal arranging device is at upper and lower belt wheel On the saw frame panel in left side；On the left of saw frame, the middle part device by above-below direction has one laterally to be fixed connection by bearing casing cabable Hand wheel shaft, hand wheel shaft left end is connected with handwheel, and right-hand member is then threaded connection the regulating arm of an arc, the upper and lower side of regulating arm On face all activity be connected with a horizontal connecting rod, being connected on rocking arm of the right-hand member of connecting rod activity, simultaneously upper and lower elevating lever Upper and lower end face touches the top and bottom of upper and lower connecting rod respectively.

The invention has the beneficial effects as follows that bands for band is additionally arranged many from saw blade such that it is able to one by a common head saw bar Secondary cut out multi-sheets simultaneously, improve work efficiency.

Detailed description of the invention:

Illustrate the design below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, the band saw of the design comprises saw frame the 1st, saw frame panel the 18th, upper and lower belt wheel the 10th, master Saw blade 11, saw frame 1 is in approximation L-shaped, and it is the skeleton of whole device, and face is one side closed behind saw frame panel 18；With band Outside the saw blade sealing ring of head saw bar 11 that wheel is directly connected to, the 4th, regulation wheel 8 forms by drive the 12nd, stretching wheel three wheels by In to outer device at three between the sealing ring of saw blade 17, wherein, drive about 12 each three exist in horizontal row's shape device On saw frame panel on the left of upper and lower belt wheel, as shown in Figure 5, Figure 7, stretching wheel about 4 each three be distributed in a vertical column-shaped The surface of upper and lower belt wheel, location directly below, regulation wheel 8 be also upper and lower each three in slightly upwarping shape, the shape that has a down dip is distributed in Position on the right side of upper and lower belt wheel, three kinds of wheels are all distributions symmetrical above and below, as shown in Figure 3, Figure 4；Being on saw frame panel 18 Aforesaid stretching wheel the 4th, position residing for 8 for the regulation wheel is machined with the rocking arm window 5 of vertical chute 2 and sector respectively, and the 4th, stretching takes turns The wheel shaft of regulation wheel 8 is each passed through chute 2 and rocking arm window 5 and is connected with elevating lever the 3rd, rocking arm 7, and the left end of rocking arm 7 is lived by rocker arm shaft 9 Dynamic is connected on saw frame panel, meanwhile, through chute, the position dress being in side before and after saw frame panel on the wheel shaft of stretching wheel The card being equipped with evagination correctly and can slide up and down with the position ensureing stretching wheel, soon smoothly such as Fig. 6, Fig. 7 institute in chute Show；On the left of saw frame 1, the middle part device by above-below direction has one laterally to be fixed the threaded hand connecting by bearing casing cabable 15 Wheel shaft 14, hand wheel shaft left end is connected with handwheel 16, and right-hand member is then threaded connection the regulating arm 13 of an arc, regulating arm 13 On upper and lower end face all activity be connected with a horizontal connecting rod 6, being connected on rocking arm 7 of the right-hand member of connecting rod activity, rise simultaneously Fall bar 3 lower surface touch above connecting rod, the upper surface of lower elevating lever touches below lower link, as Fig. 5, Fig. 6, Shown in Fig. 7.So, the group saw band saw of the design is just described, when needs by saw away from bigger state (shown in Fig. 1, Fig. 3) It is adjusted to saw when less state (shown in Fig. 2, Fig. 4), by rotation hand wheel 16, regulating arm 13 can be moved to the left, connecting rod 6 Rocking arm 7 can be pulled to rotate around rocker arm shaft 9 from right to left, certain angle can be moved to the left with the regulation wheel 8 that rocking arm links together, From the saw of saw blade away from synchronizing uniformly to reduce, reaching the different regulations requiring to saw material thickness, connecting rod is this to shaking simultaneously The pulling of arm also forces the oscilaltion bar being in contact with it to moving up and down, thus the stretching also synchronizing respectively encloses from saw blade, it is ensured that Saw blade operates normally；The head saw bar driving again in driven by motor belt wheel due to power resources, other are from the power master of saw blade Drive to be leaned on, regulation wheel carry out work by the revolving force of head saw bar transmission, and this requires that the power of supporting motor is wanted suitably Increasing, simultaneously this structure and the transmission of such power make turning to of adjacent saw blade be contrary, and due to from inside to outside The length of each circle saw blade is gradually increased and the rotating speed of saw blade also can be made slightly to reduce, the about poor 1/4-of rotating speed of rough calculation Internal and external cycle once 1/3, this has no effect on normal sawing, and the difference of adjacent saw blade turns to, and can have the stability of saw material during Cutting indexes Profit.Owing to bands for band is additionally arranged many from saw blade such that it is able to once cut out plurality of plates simultaneously by a common head saw bar Material, improves work efficiency.
