Description

-Lj

The invention relates to the woodworking industry and can be used in production. calibration of wood-based panels used in the furniture industry.

A device for two-sided thickness calibration of chipboards is known, including a frame, a feeding device with spring-loaded rollers, lower and upper cutting tools, a receiving device and an actuator 1.

The disadvantage of this machine is the difficulty of accurately positioning a workable board for removing the numbered allowance from both of its stor at a time.

Also known is a machine for double-sided kashibrovani wood boards, including a bed, spring-loaded rollers with clamping elements, a calibration unit in the form of upper and lower gauge heads with overlapping end mills with cutters located on their periphery, a receiving device and a L2il drive ,

The disadvantage of this device is the low quality of plate calibration.

The purpose of the invention is to improve the quality of plate calibration.

The goal is achieved by the fact that in the device the end mills are equipped with discs that are rigidly fixed on the end faces of the cutters and are made with evenly distributed cuts on their periphery, the number of which is twice the number of incisors, and the incisions of each disc alternately cover the incisors of the milling cutter, based on the element corners, the horizontal flanges of which concentrically cover the mills in the plane of plate calibration, and the vertical ones are rigidly connected to the axis of the spring-loaded drum.

FIG. 1 shows the kinematic diagram of the machine; FIG. 2 is a view A of FIG. 1 (on top of milling heads),

The machine includes a frame 1, spring-loaded rollers 2 with clamping elements 3, a calibration unit consisting of the upper 4 and lower 5 calibrating Heads, a receiving device 6 and a device 7 for inspecting the calibrating heads, made with a power cylinder 8.

The top 4 and bottom 5 gage heads consist of spindles 9 installed on the ROW with end mills 10 that span the width of the slab processing, on which the cutters 11 are placed on their periphery. electric motor 14,

The end mills 10 are rigidly fixed disks 15, made with evenly distributed along their periphery notches 16, which alternately, through one, enclose the cutters 11, so that when crossing the path of rotation of the cutters 10 adjacent spindles 9 one of the notches 16 encloses the cutter 11 of the adjacent cutter 11 spindle

The lower and upper clamping elements 3 are made in the form of angles, the horizontal flanges 17 of which concentrically surround the mills 10 and form protrusions 18 in the spaces between them, and the vertical flanges 19 by means of levers 20 are rigidly connected, respectively, to one of the rollers 2, the rollers 2 are suspended on hinges mechanisms 21 and 22, interconnected by means of meshed sectors 23 and 24, and closed by spring 25,

At the exit of the calibrating heads 4 and 5, a receiving device 6 is mounted, which contains the lower table 26 installed at the same level with the calibration head and the lower head. The bottom table 26 is made with lugs of the angularly horizontal shelf 17 of the clamping element 3. A spring-loaded roller 27 is installed above the table 26

The machine works as follows. The plate to be processed is fed into the machine feed mechanism. At the same time rolls

2 and the clamping elements 3 with the corners are moved apart due to their interaction by means of the gear sectors.

23, 24, hinge mechanisms 21, 22, springs 25 and levers 20, orientiru processed plate strictly into the space between face mills Y. At the moment of Starting processing, the edge of the plate is clamped between the clamping elements

3 and discs 15 and due to the horizontal section of the cutter section

17 with the protrusions 18, the latter overlap with the outer part of the disks 15 and create continuous two-sided contact of the processed plate with the supporting surfaces, providing a reliable base in the cutting zone.

Since the cutters 11 of the Mills 10 protrude above the disks 15, an airbag reducing the vibration of the plate is created between the surfaces of the plate being calibrated and the disks 15.

The processed section of the plate at the exit of the calibration unit rests on the lower table 26 and is pressed against it by the roller 27, forming also two-sided contact of the plate with the supporting Surfaces by overlapping the projections 18 of the lower table 26 and the disks 15 of the end mills 10, which improves the calibration quality plates
