Description

UNIVERSAL WOODWORKING MACHINE The utility model relates to the field of processing and

in particular, to equipment for the processing of fine round timber.

A well-known cylinder machine of the German company WEHft PR06ST is designed to produce round wood from untreated logs by removing the outer layer of wood while moving the log through a rotating knife head (Appendix 1). The machine is highly specialized and performs only one operation - cylindering.

Famous Finnish milling and chipper HFW 5AV /, R20Q equipped with milling heads and a multi-saw device from circular saws. (Appendix).

The machine allows you to get finished products in the form of bars and boards, but from untreated logs, since it does not have a device for cylindering the processed logs, which significantly reduces the technical capabilities of the machine and the yield of commercial wood.

The closest in technical essence to the claimed object is the German line of the company WEMA PR06ST for the production of beams and boards (Appendix 3) from a tonometer.

. The pin includes a feed conveyor, a cylinder and a groove. Red-lumbering jigs, an intermediate conveyor and a multi-saw machine with current pools. All equipment is mounted in a single technological chain.

The disadvantage of the line is its bulkiness and length of up to fts 50 meters, which is why it takes up a lot of production areas. In addition, the machines themselves are quite bulky and meta-tight.

The purpose of the utility model is to create a compact universal machine for woodworking, in which it would be possible to place cylindering, milling-timbering and multi-sawing devices on one bed, which allow several technological operations with it to produce high-quality timber and boards with one pass.

The delivered spruce is achieved due to the fact that in a universal woodworking machine that contains a bed and a feeding device with rowan nuts placed on it, a milling and blocking device with adjustable size limiters for the workpiece, as well as a multi-saw device from circular saws with feeding and exhaust rowan and a device for clamping them to a workpiece, according to a utility model, the machine bed is made in the form of a prefabricated welded construction and is equipped with a cylinder device located between while the distance between the plane passing through the edges of each knife of the cylindering device and the plane passing through the axes of the milling and brushing device is (4, and the distance L is the plane passing through the axis of the milling of the milling and grinding device and the axis of the saw shaft of the multisaw device is L2 (8-g 1b), where i) tf / is the minimum diameter of the finished machined part.

In addition, the cylindering device and; milling and chipping device are made in a single housing.

It is advisable that the axis of the milling cutter of the sifter-grazing device and the axis of the saw shaft of the multi-saw device are located in a horizontal plane.

Preferably, the adjustable size limiters of the workpiece of the milling unit, and the feed and exhaust swell of the multi-saw device are performed in accordance with the profile of the finished machined part.

In current flow, it is necessary that the clamping device of the supply and exhaust pit of the multi-saw device is equipped with an elastic-elastic damping of a small stroke, made, for example, of rubber.

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

Fig L is a front view of the machine.

The proposed machine (Fig, 1,2) contains a welded complex configuration of the frame 1, on which is mounted a feed device with rowan. For it, by means of bolts fixed

a single casing of the cylinder 3 and milling-blocking 4 devices, thereby forming a prefabricated-welded frame structure.

The cylindrical device 3 is equipped with a through hollow spindle 5 with machining cutters b and an autonomous electric drive.

 The milling and brushing device 4 contains two horizontally arranged mills. The milling heads 7 are height-adjustable and have two height-adjustable milling heads, with limiters 5.

Multisaw device 9 is mounted for; milling and chipper device and is equipped with circular saws 10, the axis of which is located horizontally.

Before saws 10. are placed: feed 11, and after them exhaust 12 rowan, which is attached to the profile of the machined part (figure 2). The grouse are pressed to the workpiece by a squeezing device 13 with elastically elastic dampers of small stroke 14, which ensure a fixed fixation of the finished parts at the exit and, accordingly, their purity and quality of processing.

The drive of all the pockbacks, including feed 2 and multi-saw devices 11 and 1., is carried out from a separate electric drive through a gearbox 15 and a chain gear 1B (Fig.2).

The compactness of the machine is achieved due to the placement of cylindering and milling-blocking devices in one case, and also due to the selection of optimal sizes L between the plane passing through the ends of the Eutria of each knife of the cylindering device and the plane passing through the axis of the mill of the grinding-blocking device and beyond. account of the distance LS between the plane passing through the axis of the milling of the milling-blocking device and the axis of the saw shaft of the multisaw device, which are L i (4 Q), and L 2 (8 h-, the minimum diameter of the finished workpiece.
