Description

one

The invention can be used in the woodworking industry.

A planer is known for planing wood, comprising a housing, an electric motor and a cutting tool.

The purpose of the invention is to ensure smooth operation and increase the purity of the treatment.

This is achieved in that the cutting tool is made in the form of blades having the shape of an Archimedean spiral fixed to the motor stator flush on which the holder with tap holes is rigidly mounted, the plane of the plane is made with a lid in which the window is selected, and the electric motor is equipped with a fan.

FIG. 1 shows the electric planer, general view and node I; in fig. 2 is a view along arrow L in FIG. one.

The electric plane has a circular shape and includes a corrus /, a cover 2, an electric motor 3, cutting blades 4, having the shape of an Archimedes spiral, and rollers 5, providing a predetermined thickness of planing.

In the lid 2, a window a is selected through which the chips coming from the working bodies are removed by means of the fan 6. The cap is bolted to the body / planer. On the lid 2, the front 7 and rear 8 handles are fastened for ease of operation. An electric motor switch is mounted in handle 8. In the plane of the plane, an electric motor 3 is fixed, the stator 9 of which rotates in the thrust bearings 10, and the measles L are rigidly fixed in the lid 2. Rigidly mounted on the stator

a holder 12 having tap holes 13 for removing chips from cutting blades that are attached to the tap hole with screws 14. A fan 6 is located in the upper part of the electric motor stator, which sucks the chips from cutting blades (chip movement in Fig. 1) and cools motor overheating.

On the plane of the planer movably fixed with bolts 15 restrictive ferrule 16, for

adjusting the thickness of the planing, at the bottom of which there are four movable rollers 5, which provide ease and smoothness of the electroplaning movement.

Electric plane works as follows. After a preliminary check of the planer and the installation of the restrictive holder 16 to a predetermined thickness of the planer, the electric motor 3 is turned on and, taking the handles into the plane, is placed on the edge of the board to be processed so that the knives do not touch it; and begin to move the plane forward on the treated surface. The feed of the planer should be uniform. There is almost no need to press the handles, as for planing

enough weight of the planer itself. Small

The focus should be on the rear handle. Archimedes' spiral knives move along the surface being processed, rotate in the plane of planing, remove chips and direct them to the entrance to the cutting blades, where the chips capture air from the blown air from the fan and throw it out through the window in the plane of the plane. A flexible chip breaker can be connected to the window and the chips can be routed outside the workshop. The circular movement of the knives in the cutting plane allows one to get rid of the waves on the machined surface, which increases the cleanliness of the treatment. Such an electroplane design creates the condition for the simultaneous planing of wood along and across the fibers.
