Description

The invention relates to the processing of metals by pressure and can be used for the manufacture of co -, commercial, aggregate.

A device for manufacturing a honeycomb of strip material is known, consisting of sequentially installed mechanisms for producing rows of longitudinal slits, made in the form of circular knives, a mechanism for transverse corrugation of strip material, made in the form of profiled rollers that simultaneously move the material, mechanism bending successively along the line of cuts to the formation of honeycomb cells, which is a system of bending rollers mounted on transverse s relative to the material and gradually shafts of increasing count from the shaft to the shaft, and for finally forming 1-cell.

On the known device can only be obtained flat honeycomb aggregates.

A device for manufacturing a honeycomb tubular form filler from a strip material is known, comprising a material feed mechanism, a blade unit, a strip material fixation mechanism and a bending mechanism 2 successively installed on the frame,

This device makes it possible to manufacture a honeycomb tubular filler of limited length, since the length of the resulting tubular mold is formed by the width of the material.

The purpose of the invention is to manufacture a honeycomb tubular filler of unlimited length.

To achieve this goal, the device is equipped with a mechanism for fixing corrugated material, kinematically associated with a feeder placed behind a die and made as a pair of toothed rollers with a 0 tooth profile corresponding to the shape of the cell floor of the honeycomb, the cutting edges of the knife unit are installed along the material feed direction , wherein the stamp is provided with a fixing punch, spring-loaded in the direction of its stroke, and a fixing matrix rigidly connected with the matrix for corrugation by means of a shaped nd firing line); 0 a single unit installed with the possibility of axial movement, and the bending mechanism is made in the form of axes with rollers mounted for rotation, of which two axes are bent along an arc and placed concentrically, and one is curved around the circumference, perpendicular to the feed direction.

FIG. 1 shows a diagram of the proposed device; in fig. 2, section A-A in FIG. one; in fig. 3 section bb in fig. one;; in fig. 4 shows a section B-B in FIG. one; in fig. 5 a section of YYY in FIG. 1 (supporting rollers of the mechanism are flexible); in fig. b -, section DD in FIG. I; in fig. 7 kinematic diagram of the device.

The proposed device comprises a frame 1 on which a bracket 2 is installed with an axis 3 for the material and a column 4 for guiding the top plate 5, a carriage 6 of the material feeding mechanism with clamping elements in the form of a fixed jaw 7 and a spring-loaded jaw 8 which is clamped eccentrically roller 9. On one axis with roller 9, cam 10 is secured. Carriage 6 moves from the top plate 5 by lever 11, cam 10 receives movement from the top plate through lever 12.

On the bed 1 is installed the lower unit 13 knives, on the top plate 5 fixed upper unit 14 knives. The cutting knife blocks are installed along the material feed in two rows, the second row of knives is offset from the first so that the blades of the knives are arranged in a checkerboard pattern.

Next to the knife unit, a fixing mechanism 15 is placed, the clamping material, when cutting by knife blocks, is a sponge, which is kinematically connected to the carriage b of the feeding mechanism by a spring-loaded lever 16, which in turn receives movement from the cam 10. On the base 1 on columns 4 Also, ycTjaHOBjieHH is made in a single block, a corrugation matrix 17 and a fixing matrix 18, and a platen 19 for corrugation and a spring-loaded in the direction of travel of the punch 20 for fixing are fixed on the plate 5.

A block of dies with the help of levers 21 and 22 is connected with the plate 5, the edge connecting the dies is profiled.

The fixation mechanism - corrugated material consists of a pair of toothed rollers 23 and 24, the tooth of which has a profile corresponding to the profile of received cells. Upper roller 24 is connected via lever 25 and 26 to the carriage b.

A flexible mechanism is also installed on the frame, consisting of axes 27 and 28 located on supports 29 concentrically one another in a plane perpendicular to the feed direction — on which the bending rollers 30 are mounted with the possibility of rotation, and parallel to them and axially 31 circumferentially formed, on which bending rollers 32 are located. Axis 31 is fixed on support 33. Support rollers 34 are mounted on supports 35 between axles 27, 28 and 31. Supports 29, 33 and 35 are fixed on bracket 36, which in turn is fixed on frame 1. 5 device running trace yuschim manner.

In the initial position, the upper plate 5 is in the lower position, and the feed carriage 6 is in the extreme 0 right. The material is loaded into the carriage, pushing it all the way to the line of the Vlok 14 knives. After this, the device drive is turned on, plate 5 goes up, and carriage B moves the clamped material to the left by a step.

In the subsequent course of the plate 5 downwards, the blocks 13 and 14 of the knives perform two rows arranged in checkerboard order. During the subsequent Q feed of material per step, the material enters the fixation mechanism 15 and during the course of the plate 5 is clamped down by it, at the same time the next two rows of cuts are made. Fixing. with the material, the mechanism 15 is carried out as a result of the rotation of the spring-loaded lever 16 from the cam 10. The cam 10 turns at a certain angle when pressed on it by the lever 12.

 After the material is clamped by the mechanism 15, the carriage b under the action of the lever 11 moves to the right. Upon subsequent lifting of the plate 5, the mechanism 15 fixation releases the material, 5 and the carriage b feeds it to the step. In subsequent feeds, the material enters the arrangement of the dies 17 and the punch 19, while the plate is running down, the levers 21 and 22 move the block of dies 0 upwards, and the punch 19 lowers, realizing the entire width of the material.

When PLATE 5 goes up, the matrix blocks down and allows the molded cavity to move a step. Upon subsequent lowering of the plate 5 down spring-loaded punch 20 fixes a hollow formed by the punch 19 along its entire length, and the punch 19 stamps the next hollow. At the same time, the material, tensioned between the punches 19 and 20 on the edge of the block of dies, takes the form of this edge, having a height and width varying by the distance of the slots 5. 5. In subsequent feeds, the molded material enters the rollers 23 and 24, which serve to fix the FDI material in a horizontal position when it is bent by a bending mechanism and to feed it together with the feed carriage. Pass the fixing rollers J. and 24, the material in the initial stage was manually filled into the bending mechanism between the bending rollers 30 along the cutting lines. Thus, the rollers located on axis 2B were at the jumpers of the apex with a wide part of it, and the rollers located on axis 27 were located After the material is loaded into bending rollers 32 located on axis 31 so that the lines of bending rollers 30 of axis 28 coincide with rollers 32 during the established roller process they form a tubular filler of infinite length. The device provides accurate fabrication of the elements of the honeycomb filler, this increases the quality, strength and reliability of the products ...
