Description

The utility model relates to woodworking, namely to tools for mechanical decorative processing of wooden blanks and can be used for the manufacture of complex and original profiles of carpentry.

Known milling cutter for mechanical decorative processing of wooden billets of conical or cylindrical shape, including a body and cutting edges made in the form of concave elliptic curves symmetrical about the axis of rotation (RF patent No. 2067045, V27C 5/00, 1996)

A disadvantage of the known milling cutter is limited functionality due to the processing of only cylindrical or conical blanks.

Known shaped milling cutters for decorative milling of wood, containing a shaft with a shank for fixing in the spindle of the machine, knives with a cutting edge of a certain profile, mounted on the cutting part of the rod. (M.S.Glikin, “Decorative woodwork on machines,” GPI “Iskonne,” Moscow, 1997, figure 43, p. 113).

Currently, woodworking tools (hand milling machines, milling tables) for decorative processing of carpentry, where mills with carbide cutting edges with cylindrical shanks are used, are in great demand. Milling cutters are made of high quality materials and are characterized by precisely calculated geometry of the cutting edge processed by diamond blades, due to which high quality of product processing is achieved.

The objective of the utility model is to create a wide range of milling cutters that allow not only complex and original profiles to be obtained, but also simple mills to be used in the initial processing of the material to facilitate the operation of milling cutters with a complex profile or large working diameter.

The task is achieved due to the fact that the woodworking mill, containing a rod with a milling head, on which plates with carbide cutting edges are fixed, a cylindrical shank for fixing the milling cutter on the spindle of the milling machine, according to a useful model, the milling head contains a thrust bearing with a compression nut, interacting with a workpiece guide or a template that repeats the shape of the workpiece profile.

The inventive milling cutter, depending on the required processing of joinery blanks, contains inserts with cutting edges corresponding to the profile of the workpiece, for various types of joints, grooves, edge trimming, decorative processing of furniture and interior details: columns, table legs, chairs, etc.

Production of complex and original blank profiles is carried out by various types of milling cutters:

- Grooving cutters - straight, fillet and shaped;

- edge milling cutters - straight, molding, seam, curly, conical, fillet, half-rod;

- milling cutters - horizontal and vertical;

- milling cutters combined.

The claimed utility model is illustrated by drawings, which show examples of various types of mills.

Woodworking mill (figure 1) contains a shaft with a shank 1 and a milling head 2 with cutting edges 3. The mill is equipped with a thrust bearing 4, mounted on the shaft of the rod. An adjusting washer 5 is installed between the milling head 2 and the end of the bearing 4, and a lock washer 6 is installed from the other end of the bearing 6. The assembled cutter is tightened with the nut 7.

Bearing 4 allows you to use the template for the manufacture of a profile groove groove cutter. It makes it possible to use edge molding and seam cutters, both along the straight and curved edges of the workpieces along the entire length. When changing the bearing, it is possible to obtain different depths of seam folds along the edges of various curvatures.

Milling grooving straight lines (figure 2) and shaped (figure 3) are used for decorative processing of joinery: edge processing, application

drawing according to the pattern on the plane of door panels, hinged plates, decorative plates of the interior.

To produce a profile groove according to the template, a mill with a bearing is used, with which a template is rolled.

In the manufacture of a wood product consisting of several parts, the need arises for their rigid connection, for example, a quarter connection, a tongue and groove connection, a spike connection (box connection), a dovetail connection, etc.

Groove cutter cutters are used for decorative processing of furniture and interior details of columns, legs of tables, chairs, etc.

Edge straight milling cutters (figure 4) are designed for finishing the edges and ends of the product.

The milling cutter installed in the spindle of the milling machine forms a right angle with the machine support table, which makes it possible to obtain an edge or end face strictly perpendicular to the workpiece plane during milling. Edge straight milling cutters can be used with a template, as an emphasis for the bearing. In this case, it is possible to produce decorative parts of various configurations.

Milling edge milling cutters (Fig. 5) make it possible to produce carpentry, furniture and interior items in various styles, as well as indispensable when performing restoration work. A wide selection of molding milling machine configurations is combined with a large selection of profiles of combined milling cutters, which allows you to maintain the style when performing all carpentry work, in the manufacture of furniture and interior elements.

The thrust bearing makes it possible to use casting milling cutters, both on the straight and curved edges of the parts without additional equipment.

A wide range of profiles of edge milling machines makes it possible to use a combination of different mills to obtain a complex profile.

Edge seam cutters (Fig.6) are designed to obtain a straight line seam with a seam, quarter sampling, obtaining a groove or tenon along the edge of wooden blanks. The presence of a thrust bearing allows you to mill both straight and curved joinery blanks along the entire length. When changing the bearing, it is possible to obtain different depths of seam folds along the edges of various curvatures. They are used for joining blanks in a quarter, making a groove for installing door panels, milling folds for picture frames, folding elements of cabinet furniture.

Edge conical cutters (Fig. 7), fillet (Fig. 8), curly (Fig. 9) allow you to get a variety of types of edge profiles of products, both individually and in various combinations.

In addition, it is possible to use individual parts of the working edge of the cutters to obtain a decorative profile.

Various combinations of molding and curly milling cutters allow us to produce carpentry, interior items and furniture of different profiles.

Horizontal milling cutters (figure 10) with a large working diameter are intended for decorative processing of the edges of panels.

The cutters are equipped with a thrust bearing, which allows you to process not only the straight, but also the curved edge of the product.

Vertical milling cutters (11) are designed for deep milling of the edges of joinery (panels). These cutters allow you to get a decorative frame and a spike along the edge of the workpiece in one pass.

Vertical milling cutters do not have a thrust bearing, therefore they are used with the emphasis of the milling machine, or with the emphasis of the milling table.

Figurine vertical milling cutters are used in the manufacture of straight skirting boards, as well as decorative trims for the manufacture of cornices and interior details.

For the manufacture of wooden boards by joining boards along the edge and joining joinery parts along the end (building), combined milling cutters are used, which are a combination of groove and tenon milling cutters, the milling heads of which are combined into one mill (Fig. 12, Fig. 13), or delivered in set of groove and tenon cutters.

These milling cutters in one pass perform a spike and a groove on the machined surface, which allows processing both sides of the workpiece without removing the milling cutter from the milling machine.

The design of combined milling cutters allows you to change the location of the working parts of the cutter to perform various jobs, which makes the cutter universal and indispensable for carpentry.

The manufacture, for example, of frame joints is carried out by rearranging the cutting parts of the cutters and the bearing. One part of the connection is performed by a milling cutter with a bearing mounted under a set of milling heads from two milling cutters (Fig. 12) for selecting a groove and processing the front part of the workpiece and then, having installed bearings between them (Fig. 13), they perform a spike and a backward recess. Both parts are then joined (Fig. 14).

Using the capabilities of combined frame milling cutters, you can make various connections for the manufacture of frame furniture, wall panels, interior items, etc.

To increase productivity and ease of use, cutters are manufactured in sets formed to perform special tasks.

Kits allow you to perform all operations in the manufacture of elements of frame furniture, panel products, etc.

The presence, for example, of two combined frame mills makes it possible to reduce the amount of time spent on the manufacture of frame connections.

Kits for decorative use are used for decorative processing of furniture and interior details: columns, table legs, chairs, for various types of joints, grooves and edge processing.

To process the blanks according to the template, copy sleeves are used, which allow you to process curved edges parallel to the sample. Using a set of copiers, you can mill dovetail connections, stepped machining, and turning letters and numbers. The copy sleeve is inserted into the hole of the mill frame and locked with a lock nut. The cutter is inserted into the bore of the sleeve and is mounted in the collet of the milling cutter. The guide sleeve slides along the template and copies its profile to the workpiece.

The use of woodworking cutters allows you to get complex and original blank profiles in the manufacture of carpentry in industrial production, and especially in carpentry workshops for the manufacture of individual orders.
