SU116813A1 - Device for making window sashes and other wood fiber products - Google Patents

Description

The subject of the invention is a device for the manufacture of window stacks and other wooden fiber products using a hydraulic press for pressing products into shaped matrices, which are moved periodically but without a stationary ring roller table, and a vacuum forming device for casting shaped articles in mesh matrices. Known for these purposes The devices do not ensure that the pressed products are kept under pressure in the dies after the cessation of the hydraulic press.

In the device described, this disadvantage is eliminated due to the fact that the dies are equipped with spring-loaded pneumatic latches that firmly couple the matrix to the punch, and to dry, the matrix products are pressed into the matrix and provided with steam through the steam pipes from the central steam distribution device.

FIG. 1 shows a general view of a device with hydraulic pres and a roll table; in fig. 2 - sectional view of the matrix; in fig. 3 - vacuum-forming device in cross section.

The device consists of a hydraulic press /, shaped marshkp 2, an annular roller table 5 and a vacuum-forming device 4. For pouring out the shaped articles in mesh matrices

To hold under pressure in the shaped dies of the pressed products, after the hydraulic press ceases to work, the dies 2 are equipped with spring-loaded pneumatic latches 5, which firmly couple the dies to the punch 6. The dies also have cavities 7 for entering steam into them through steam-water pipe 116813

Cam from the central steam distribution device. The pneumatic latches are driven by compressed air and placed on the punch. The matrix has a tapered bore 8, into which the taper 9 enters at a pressure of compressed air on the latch porschen 10.

The vacuum forming device consists of a vacuum chamber 11 connected to a vacuum pump 12, a forming and charging mesh matrix 13 having the shape of a manufactured article, and a pulp bin 14 for pulp. The vacuum forming device is connected by a conveyor / 5 to a hydraulic press /.

The manufacture of window covers and other capital products using the described device is as follows.

From the dispenser, a portion of the liquid wood-fiber mass that fills the screen matrix is fed into the hopper of the vacuum-forming device, then the vacuum pump is turned on, and vacuum is created in the vacuum chamber, so that the blank is cast into the matrix by dewatering the liquid mass. After the casting of the mesh, the matrix together with the workpiece is moved by a conveyor under the hydraulic press, where the workpiece is pressed into the matrix to a predetermined size, the pneumatic latch firmly interlocks the die with the die, and the cavity is heated in the cavity, which results in sealing and the substance of the product, as well as the polymerization of sizing materials. Then, the hydraulic press is turned off, and the die with the punch and the product pressed into it moves along the ring roller table for some distance. Thus, making a periodic movement along the roller table, the die with the punch again enters the loading position, the product is released from it, and the cycle of work is repeated.

The product profile is determined by the configuration of the die and punch used, by changing which products of any configuration can be made from both liquid pulp and dry shredded wood.

Claims (2)
