Description

Changing saws in the frames of sawmills usually takes place at the time when they get into the machine. This change is always troublesome and, accordingly, takes a lot of time, since parts of the gear to the frame, and especially the transverse reinforcement of the frame legs, make it difficult to reach the frame with nylamin, hollow: inside. On the other hand, the tension of the sheet saws in the cutting direction, but a plumb with outweighing should be done exclusively by the foot, since otherwise the work on the | nilovke nshoamozhna. Depending on the number of saws and the method of their fixing, it is considered from 30 to 80 minutes for the exact outweighing of the room (set). This time is lost, of course, for the cutting work. The loss of time of sawing and reduction of water productivity and utilization of forest stands is particularly subtle when sawing into thin boards (here there are many hanging panels of saws), and with the drive lines of the construction company -. patiently, nowadays, little saws often take them off. In order to facilitate the work of re-singing the saws, you can use the special rollers in special frames, at which an ecgomi is obtained, approximately, about V of the above mentioned time.

There are a shear, in which the frame with the saws can be removed from the machine and in which, therefore, there is no overlap of the frame frame in the form of transverse reinforcement, which would make it impossible to take out the frame with the saws. With such devices, timber cuttings, which allow removal of saw blades, the change of these NRLs is carried out with the saw frame remaining in the machine. The ability to remove the frame for saws serves in these famous sawmills only for the purpose of assembly, but does not allow quick change during operation.

 The proposed inventor has the aim to stick around the possibility of changing the saw blade for the saw blade. For this purpose, slide guides for the sled are made obliquely and support axial trunnions having each profiled NODSHSCHEK, which is supported by a support consisting of two parts in such a way (ng such that the upper part 1; ripens to the lower part of the seed. the frames with the saws and the last lift up with the help of guides. You can remove the frame for NIL using an idler (for example.

In frame 1 of the locally cut sawmill (Fig. / 1), when it is covered with conventional cross members 2, the frame is vertically frame with nilias, which consist of upper beam 3, lower beam 4 and connecting bars of weight 5. In these frames, nn 6 linen The sawn cuts of transport materials (ooo auggs) with known rolls 7, as well as trolleys for carrying them, are drawn but nil 8 of the working room. On the inside of the stitches of the walls spliced into each other (W 1 and the frame frame, according to FGI. 2, there are guides 9 for the frame and tailgate, which are open at the top and about their length, are commensurate with the length of the frame's run. for hanging a beam 11, provided with one or several openings for hanging 1 frame frames of various sizes, locks the block 12, which is attached to the trolley 13. Using this tool, the sawmill frame can be removed from the machine itself upwards and then taken along the beam 13. into the room for t NILE glasses. The NILL sawmill frame, which is ready at the ready, can be immediately brought to the place of the frame taken out of the machine.The change and point of noloten PP & is made in the upper room, the wave of which is marked with a figure 14 in Fig. 1.

The upper beam S of the Lesmgalsi frame has, according to FIG. 3, at collet 15, behind k (tfie capture the connecting rods 16, with which the sawmill's frame moves up and down with its guides. The axles 17 are fixed on the trunnions, in the form of circular washers with KftoD 18, having inside ball bearings 19, which covered entirely by the eye of the upper end of the connecting rod 16.

With the device (the Leg, the satellite of Fig. 8, the protrusion of part 21 of the core has a hole 23 through which the bolt 24 is pressed against the bottom of the shroud; the bolt has a slot that serves to lay the checks 24.

The vanes 9 of the timber frame have a section, as shown in FIG. 9-12, in the dovetail inlet, but with which the guiding parts 26 of the upper balochas 3 and the lower 4 slide. For ease of insertion of the frame, cuts are made either 27 (Fig. 11) or 28 (FMG. 9) ..

The mounting board-Lb of the lower gear is rotated on the axis 37, which is supported by a 38-pillar 38 strut 29. On the top board of the board; 36 has an axis 39, which can rotate up to 40 of the rack 29 (Fig. 17), and with eccentric washers 41 , rotate the board 36 near the axis 37.-This turning serves to accurately set the inclination of the DOSEN 36 according to the well-known overhang of the PNL pin on the chassis of the saw. The 11 (h) shaft 39 is produced by using the above-mentioned at its free end of the handle 43, whereby the corresponding shaft 39 passes through the box 44 of the box 31 so as not to interfere with its movement. The handle acts on the arc 45 from the side of the mn and the adjusting knob 46 of the SSK on the cheek, so that in each position indicated by the arc with delos mn, there may be a different setting of this knob 4b.

The blades ppl 6 are laid in a known manner at an appropriately old distance from each other in the frame of the sawmill with the help of 1-gauge industrial calibers 47. For these (pads) in the board 36 there are holes 48 (Fig. 13), which can include ends of calibers. For the first one, installed on one side of the sawmill frame, the saw blades are installed, in addition, there are anvil 49 on the stand 29. The first saw blade of the corresponding saw is placed on these holes (L surface. The first saw blades set the position of all other saw blades.

In the upper part of the sawmill of the base of the saw bed 1 saw shown in the drawing (fig. 18 and 19) (with the other opposite steel strut 1 using a hollow pipe2) the pipe has flanges 50 at the ends, and the crossbones with the beds are screwed together. connect nd (zhvoditsya in the place where are located prdpppsh kn shaft52 with zyatcharshp 53.

On the flanges of the fastening pipe 2, there are upper bevels 57 in the form of an inclined surface 5.

In order to particularly protect the Aubut Rail, bevels, as seen in particular in FIG. 18, 19 are also supplied with a special roof-shaped protrusion 59, the quvec 60 which is located near, horizontally. The slopes of the roof 61 and 62 are used for throwing sawdust on both sides of the protrusion, so that traffic policemen do not get into the rack guide 54, it doesn’t fit. For removing the dust-like sawn-off of a dry tree, according to fig. 18, 19, and 20, in the toothed racks, which are recommended to be made of steel and supplied with a spline mV tooth, are made back. perhaps a wide notch 64, which runs along the tooth 65 along the entire plane of the plane of the teeth; The 9th floor of the top is covered with a rear stopper ((H1 (plate 66 and so on into dust penetration.

The camera serves to place the drive wheel 73, which is mounted on the axis 74. The axis 74 is self-supporting toothed wheel 75, which engages the toothed ear 76 on the axis 52 of the gear wheel 53.

However, the object to be sawn W (cf. fig. 26) is generally of a single diameter.

In the raised position, these parts are proven in FIG. 26 dotted lines. In this, the feed rollers pressed down on the object being sawn by the action of their own weight and the weight of the rack. But, besides, the ECHLING of the feed roller rotates the gear wheel 53 and rotates the transfer to transfer 75, 76. As a result, the axis 74 also rotates together, as well as the wire wheel 73. 6 atroc the protrusions 77 serve as a charge that keeps the rotation of the shaft 70 ; Thus, this axis together with topoSKoi 71, 72 is moving, with the rotation iitKxnBteee 71, people still less than 10 mm on the back of the | DixM.
