Abstract

The suggested solution is intended to method and device for producing of finishing bricks by using whatever constructional bricks. The object of the invention is to increase quality of the finishing bricks and reliability of the device. A blank is hewn from the end to the center. Cutting tools are mounted in sequence in line, the cutting edges of which setting-up a broken line and they themselves are mounted fixedly in respect of each other and are placed at an angle to a treating plane so that all cutting edges will be in the same trajectory turning its around the freely chosen axis and a clamping mechanism is mounted pivot ably around said axis.

Description

The present invention relates to a method of producing decorative relief bricks using any building bricks.

There is a known method of manufacturing embossed bricks and a device for the Rokkmaster II Maci. 62001 Tebberman Engineering Almelo-Holland, AB of Matuizų plytinė AB, whereby the blank is placed on a conveyor and fed into a clamping mechanism between two vertical, horizontally movable rubber conveyor belts so as to remain uncovered. part of the brick for scraping. On each side of the brick, two rotating gearing tools are mounted perpendicular to the direction of movement, which simultaneously cuts both sides of the brick in sequence.

This method of paving does not guarantee quality when the bricks are fed at intervals when the bricks are fed into the paving area. Patching bricks are the edges of the brick that are over or under, at the beginning or end of the putty. The machine is very sensitive to fluctuations in the thickness and strength of the bricks, because the bricks are fed with rubber bands into the gating zone. Common bricks smaller thickness, even within the tolerance (during dressing) is withdrawn from compres- rubber bands and impermissibly falls within the dressing tool and the dressing mechanism breaks with increased strength of 250 kg / cm ^2, brick in general can not be shaped.

The closest technical solution we offer is the SU 1560434 Al B 28 D 1/26, where the process is performed using tools mounted in one plane, but this solution is intended to be cut across the entire length of the workpiece at a time.

Because construction bricks are used to make flat bricks with flat and parallel planes, this technique allows moving tools that are force-transmitted through the rigid elements to simultaneously slide into the brick plane as one continuous knife, and the brick cut is relatively smooth and misaligned. Requirements for decorative relief bricks.

The aim of the technical solution we offer is to ensure the quality of embossed bricks and the reliability of the equipment producing them.

This goal is achieved by applying the preparation first on one side and then on the other side, gradually stepping from the ends of the preparation to the center, in a row in a row, fixed, fixed to one another and pointed at one another '<

at an angle to the plane such that the cutting edges of all the gearing tools rotate about a freely selected axis in a single trajectory and the clamping mechanism is mounted with a possibility of rotation about this axis.

The invention is illustrated by the following drawings:

I, II, ΠΙ - Conditional breakdown of brick-ready 1 upper plane part 2 parting process into stages.

IV, V, VI - Conditional breakdown of brick-ready lower plane parts molding process into stages.

At the beginning of the process, Fig. 1, I pressed the brick-preparation 1, two edge kneading tools (not shown in the drawing) cut into surface 2 and cut corners 4 at a certain distance m from the edge; so that one side of the set is drawn from both edges to the center, FIG. 1 III, followed by analogy with FIG. 2 - Stages IV, V, VI apply the bricks - prepare the lower part of the plane 3. If the length L, the width B, the height H, then the application Bi <B. Specific sizes are governed by the standard.

The device (Figs. 3, 4, 5) for carrying out the method of manufacturing embossed bricks consists of a conveying device consisting of a conveyor mounted on a common frame 5: a conveyor - a hopper 6 with a feed mechanism 7 operating at an angle of 90 ° to its direction of movement. a patching assembly 8 comprising (Fig. 5) a crank-like parallel clamping mechanism 10 mounted on the end of the lever 9, acting from an individual force mechanism 11, with a clamping plate 12 on which a support plane 13 is mounted and adjacent, above the clamping plate 12, a lateral stop 14. In the opposite end of the clamping mechanism 10, a shear mechanism 15 is provided in the form of a shamry device 15 at the opposite end of the lever 9. It has a lower fixing unit 16 arranged at a distance of 180 °.

The tools 17 of the top tapping unit 8 and the bottom tapping unit 16 are fixedly fixed relative to each other and positioned at a right angle to the plane 18, incrementally from edge to center so that the cutting edges of all tapping tools rotate about axis 19 in one trajectory. a mechanism 10 actuated by a force mechanism 15 that tends to rotate about an axis 19 that is parallel to a line 20 connecting the outer points of the cutting edges 21, 22 of the finishing tools 17.

The brick-and-roll bricks 1 are stacked next to each other on a rhythmic conveyor-accumulator 6, or spaced base-to-longitudinal support 23. One of the operating modes: tuning, single cycle, or automatic. For example, in single-cycle operation, the conveyor-hopper actuator 25 is actuated and the brick-ready 1 is fed to a rear support 26 located at the end of the conveyor-hopper 6, which has two brick-ready 1 locking positions and the correct brick-ready 1 position. the feeder 7 makes two reciprocally movable - reversible movements of the first brick assembly 1 into the operating zone of the top knock assembly 8, whereby the feeder 7 returns to its starting position, the force mechanism 11 and the shear lever arm engage. type clamping mechanism 10, clamping plate 12 clamps the brickwork 1 to the bearing plane 13. By clamping the brickwork 1, the force mechanism 15 and the lever 9 together with the attached clamping mechanism 10 and the brickwork 1 mounted therein are rotated at an angle about axis 19, what thanks to the beginning As the turning process proceeds simultaneously from one side of the brick-preparation 1, the next pair of gearing tools 17 and at the end of the actuation of the force mechanism 15 are cut off at an angle. with both edges in the center, there is no possibility of transverse forces affecting unwanted cracking during molding, which ensures the molding quality. Once the feed mechanism 7 has been made, the two sliding-reversing movements of the brick-preparation 1 fall into the operating area of the lower bracket assembly 16, whereby the lower brick-preparation 1 is clamped and pressed in an analogous manner. 16 in the knockout assembly and is in the removable position 30. A mechanism 31 is provided for locking the bricks between the knockout assembly 31. The lateral stops 14 located in the knockout zone limit the movement of the brick assembly during squeeze-release and displacement.

According to p. 1 of the claims. The proposed method of manufacturing embossed bricks provides easier paving conditions, which directly affects the quality of the product as well as the reliability of the device implementing this method.
