SU286196A1 - DEVICE FOR MANUFACTURING PRODUCTS FROM VENEER - Google Patents

Description

The invention can be used in the woodworking industry.

Known devices for the manufacture of veneer products, having a frame, carrying driven heated drums and a loading mechanism.

The known devices are inefficient and do not provide the manufacture of products such as slot wedges for electric motors.

The purpose of the invention is to increase productivity, to ensure the manufacture of products of various lengths and the required profile.

This is achieved by the fact that the device is equipped with sub-pressurized rollers, and on the outer part of the upper drum circumferential lines are formed and the transverse tools are installed, which can be mounted at different angles relative to each other, and the outer part of the upper drum is made removable.

FIG. 1 shows schematically the described device, a general view with partial cuts; in fig. 2 - the same, side view; in fig. 3 - the shape of the grooves on the drum and the cutting tool.

mounted in the guides 5 of the frame 6. The adjustment device 7 allows one of the drums to be moved up and down to create the desired pressure between the latter during the operation of the device. The connecting gland sleeves 8 serve to supply steam to the rotating drums through the knees 9. The drums have steam passage channels 10, the number and dimensions of which depend on the steam parameters and the sizes of the drums / and 2. The heating of the drums can be done from another heat source . The drum 2 is made smooth cylindrical, and the drum / but the circumference has profiled longitudinal grooves //, the depth and radius of which can be different depending on the chip of the wedge or other shaped section product. It is possible to apply various grooves for pressing different types of wedges. On the drum /, a certain distance from each other, transverse cutting tools 12 are embedded, through which the package of finished clips is cut into

required length in the process of pressing. The distance between the tools depends on the length of the wedge. From these lengths, the outer diameter of the drum / is respectively determined. Outer part 13 of the drum / completed

Preparing various types of wedges: The working surface of the drums is polished, colored, chrome-plated.

The pre-press and feed rollers 14 serve to feed the veneer package into the drums and simultaneously press it. Into the guide rollers 14, the bag is fed by a loading mechanism 15 mounted on the table 16 and allowing one bag to be fed. The drum 2 is rotated by an electric motor through a gearbox (not shown) and a chain drive with an asterisk 17.

The described device operates as follows.

A stack of stacked veneer packages 18 is placed on the table 16 and the loading mechanism 15 is fed into the rollers 14 in a single package, which, pressing the package of the spike, simultaneously guide it between drums 1 and 2. Pre-pressing makes it possible to reduce the pressing cycle holding under pressure, which is essential and allows continuous pressing at considerable speeds.

Next, the veneer package enters heated, rotating in different directions drums 1 to 2, between which, using the adjusting device 7, the necessary clearance is established. In order to create the required pressure required for pressing this type of product (for slot wedges in the range of 120-150 kg / cm -), the size of the gap is established depending on the thickness of the spun package. Due to the contact contact of the drums, a miter or nodach of the package is created, pressing it to the required thickness, heating, dividing the package into individual parts with a cutting tool 12. Simultaneously with the pressing process, the moving package of wedges is cut into

required length. It is possible to manufacture wedges of different lengths on one device, for which tools 12 are located around the circumference of the drum / at different angles relative to each other.

The temperature of the drums is maintained within 130-150 ° C for this type of product and can be adjusted to the desired values. The speed of rotation of the reels 1 and 2 depends on the thickness of the spike package being passed through, the temperature and pressure generated, and due to the transfer of the first devices (not shown in the drawings), is adjusted to the desired dimensions. A feed speed of 1-2 m / min was used to press the groove wedges.

The described device is simple and reliable in operation, provides high performance. the water content of labor.
