Abstract

This invention relates to the manufacture of building, mainly refractory, articles made from a powdered material. The purpose of the invention is to increase productivity, simplify the design and reduce metal consumption by eliminating pressing powder on the press elements, simplifying the dosing system and eliminating idling 4 strokes. The press contains a hopper 1 for filling material, non-driven traverse 2 and 3, connected by columns 4, a matrix 5 with a drive 6, its movement, a driving traverse 7 with a punch 8, a container 9, rigidly connected with a drive for its horizontal movement, mounted on a traverse 2 The latter is provided with a punch 10 and a drive 6 for moving the die. The main cylinder 11 is mounted on the cross-beam 3, the punch 12 of which is rigidly connected to the cross-beam 7. The bunker 1 is rigidly attached to the die 5, and the container 9 is loosely mounted on the columns 4. In the process of filling and pressing the material, the container 9 covers the punches 8 and 10 and the lower part of the hopper 1, which eliminates spilling material on the elements of the press. The combination of the movement of the matrix 5, the hopper 1 and the container 9 allows to simplify the design and eliminate the idle stroke of the drive crosshead 7. 5 Il. / i th 00 fm.1

Description

11286418

The invention relates to the technological equipment of the building industry: and can be used in the manufacture of building, mainly refractory, products from powdered materials.

The purpose of the invention is to increase productivity, simplify the design and reduce metal consumption.

Figure 1 shows a press, a general view (the position of the elements of the press before the start of filling the matrix with press powder); figure 2 - the same, at the end of the back of the press powder; in fig. 3 - the same at the end of pressing; in fig. 4 is the same at the end of pushing the article out of the die; in fig. 5 is a view A of FIG. 2.

Hydraulic press for production

15

the powder completely fills the matrix 5, the flap 14 is closed (Fig. 2). The cylinder 11 is turned on, and its punch 12 presses the product 15 through the driven traverse 7 by the punch 8 (FIG. 3). After the product is fully pressed, the working fluid flows into the piston cavities of the actuator 6 cylinders. At that, their rod cavities are connected to the drain, and the cylinder 11 is also connected to the drain before the traverse 7 is removed to the punch 8 by the required amount equal to the required natural height pressing the next product. After that, the drainage of the working fluid from the cylinder 11 is stopped, and the matrix 5 with the hopper 1 with the shutter 14 closed continues to move to the right until the refractory products are completely refreshed, it contains the product 15 (.4).

bunker 1 for filling material (press powder), non-driving traverse 2 and 3, connected by columns 4, matrix 5 with drive 6, moving it, driving traverse 7 with punch 8, container 9, freely mounted on columns 4. Traverse 2 is equipped with a fixed punch 10, and the traverse 3 is provided with a master cylinder 1, the punch 2 of which is rigidly connected to the traverse 7. A drive 13 is mounted on the traverse 2 for horizontal movement of the container 9. The hopper 1 is rigidly fixed on the die 5.

The press works as follows.

Container 9 is driven 13 and flies tightly & the matrix 5, while it covers the poin: sleep 8 and 10 and partly the hopper 1. The hopper gate 14 opens, and the press powder fills partly the container 9 (the space between the punches 8 and 10, figure 1). After that, the working fluid is supplied to the rod end of the cylinders of the actuator 6, and the matrix 5 with the hopper 1 with the open flap 14 and the container 9 together move to the left.

by means of a mechanism (not shown) is removed from the pressing zone. The container 9 is led to the matrix 5 and the cycle is repeated.
