OSILINOVO-MILLING-SAW WOODWORKING MACHINE

The utility model relates to the field of woodworking, and in particular to equipment for the manufacture of parts of wooden houses and structures, preferably from logs.

The well-known German line of WEMA PRQBST company for the production of beams and boards from fine toner. (Appendix 1). The disadvantage of the line is that the oscillating machines included in the line, the milling-chipper, sawing machines and the conveyors connecting them, stretch the line up to 50 m in length, as a result, it is necessary to have sufficient production facilities.

A known machine for processing fine wood (RU 2083357), comprising a frame with a feed mechanism mounted thereon, a cylinder device, feed and receiving rollers between which a milling device and a saw block are located below the longitudinal axis of the log.

The disadvantage of the machine is that, firstly, it is intended for processing only fine-sized wood, and secondly, the roller located below the machine, orienting the log according to preliminary longitudinal sampling does not provide sufficient orientation of the log from twisting it by cutting forces during cylindering.

The closest in technical essence to the claimed object is a universal woodworking machine (Utility model No. 13881 from 02.14.2000).

The machine contains feeding, cylindering, milling and sawing devices placed on the bed and allows you to get round logs with grooves of various profiles, and

also boards of various thicknesses. The peculiarity of the machine lies in the fact that it selects the dependence of the arrangement of mechanisms between themselves, expressed in relation to the minimum diameter of the cylindrical part obtained.

The disadvantage of the machine is that it covers a very narrow range of diameters of the resulting logs, not exceeding 180 mm. In addition, the ratio of the dimensions of the machine, tied to the minimum diameter of the resulting cylindrical part, does not allow to objectively express this dependence in the range of machined parts of larger diameter.

The purpose of the utility model is to expand the operational capabilities of the machine by significantly increasing the processed diameter of the log to 320 mm, while reducing the metal consumption of the machine.

This goal is achieved due to the fact that in the cylinder-milling and sawing woodworking machine, containing the frame and placed on it a feeding device with rowan, cylindrical and milling-blocking devices, as well as a multi-saw device from circular saws with feeding and exhaust rowan, according to the utility model, the distance L 1 between the plane passing through the ends of the tip of each knife of the cylinder device and the vertical plane passing along the axis of the milling of the milling-blocking device,

is L1 (1 3) Vmah, and the distance between the plane passing through the milling axis of the milling unit and the saw shaft axis of the multisaw device is L2 (1 - b) Ohm, where D is the maximum diameter of the finished rounded part.

The minimum sizes L1 and L2 are determined by the features of the machine and it is practically impossible to perform them constructively with smaller values.

the limits of these values unjustifiably increase the dimensions and weight of the machine.

New in the machine is that due to the rational choice of sizes L1 and L2, it was possible to expand the technical capabilities of the machine by increasing the maximum diameter of the logs to 320 mm and at the same time maintain the dimensions of the prototype.

The essence of the utility model is illustrated by drawings, which depict:

Figure 1 - General view of the machine;

Figure 2,3 - examples of schemes for cutting a cylindrical log.

The inventive cylinder-milling and sawing machine contains a frame 1 of a welded structure, on which a feeding device 2 with rowan 3 is placed in a sequential order, a cylinder 4 and a milling-blocking device 5, as well as a multi-saw device 6 from circular saws 7 with feeding 8 and exhaust 9 grouse.

Experimentally, the optimal value of the dependence of the relative position of the main machine components was determined.

So the distance L1 between the plane passing through the ends of the tip of each knife of the cylindering device and the vertical plane passing through the axis of the milling of the milling device is determined by the dependence S (1) D, and the distance L2 between the vertical plane passing through the axis of the milling cutter of the milling and sawing device and the shaft axis saws of a multisaw device is L2 () D, where D is the maximum diameter of the finished rounded part.

Figure 2,3 presents examples of options for cutting a rounded log.

The work of the machine is carried out in the following order.

The raw log by the pock 3 is fed into the cylindering device 4, where it is given the cylindrical shape of a given diameter, on which the machine is configured. At

further advancement, the rounded part of the log enters the milling-blocking device 5, where it is given a predetermined profile. By supplying ripples 8, the processed log is sent to the multi-sawing device 6, and by the exhaust ripples 9 the finished products in the form of logs, timber or boards are advanced to the receiving conveyor (not shown).

The machine is quite simple, controlled by one operator and allows you to get logs with a diameter of up to 320 mm and various products from them.

The machine has been tested with positive results.
