Abstract

The invention relates to the assembly industry, namely to devices for the manufacture and assembly of heat exchangers. The aim of the invention is to increase productivity by simultaneously assembling several radiator cores. This is achieved by installing knives on the die for preliminary cutting of the tape (L) and final cutting mechanisms installed on the matrix (M) of the movable cross-bar of the mechanism of pressing the plates onto the tubes. Knives and mechanisms cut L into a number of parts corresponding to the number of cores collected. The belt blank 3 from the unwinder 1 passes the rolling mechanism 2 and enters the die 4.

Description

The invention relates to the assembly industry, namely to devices for the manufacture and assembly of heat exchangers.

The aim of the invention is to increase productivity by simultaneously assembling several cores of radiators.

The goal is achieved by installing on the stamp of knives for preliminary cutting of the tape and final cutting mechanisms, cutting the tape into a number of parts corresponding to the number of cores assembled on the matrix of the movable traverse of the mechanism of pressing the plates onto the tubes.

FIG. 1 shows the proposed automaton, general view; FIG. 2 shows a rotary die with a local section; in fig. 3 is a section A-A in FIG. one; in fig. 4 - part of the tape with a notch.

The machine for assembling the cores of plate radiators consists of a feed mechanism with a decoiler 1, a mechanism 2 for rolling the belt blank 3, a rotary die 4 with punches 5 in one rotor and, respectively, spaced grooves 6 in the other, a mechanism for fitting pdastins onto tubes made in the form of a movable crosshead 7 with die 8 on which the knife 9 is mounted for cutting the workpiece from the belt. On axis 10, hinges are mounted on the combs 11, under which are located a cassette with ramrods 12 on which cooling tubes 13 are put on.

. The rotary die 4 is provided with knives 14 and, accordingly, grooves 15 for making a notch 16 on the fed tape blank 3.

On matrix 8, the mechanisms are arranged in pairs. 17 final cutting of the filed billet into plates 18 according to the number of cores collected. Each of the mechanisms 17 is a four-hinged hinge and consists of a stand (die body 8), a driving rocker (comb 11), a connecting rod 19 and a follower rocker arm 20 (the rocker arm 20 is installed in the die body 8 on the axis 21).

The machine operates as follows. The belt blank 3 is made of unwrapping device 1 and passes through the rolling mechanism 2 and enters the rotary die 4. When the dies are pulled through it

A bath tape with punches 5 and grooves 6 is stitched — to form holes for the cooling tubes 13 and, at the same time, the knives 14 and grooves 15 installed in the die cut the tape 16 in the transverse direction, leaving undercutting along its edges, which ensures the rigidity of the workpiece. pushing it into mattress 8.

Then the tape is fed into the matrix 8 to the supporting combs 11. Tra-. Versa 7 starts down with matrix 8 and belt stock. At the beginning of this movement, a piece of knife 9 of that part of the tape that went into the matrix occurs, and it is placed on the ends of the ramrods 11 that are oriented by combs. Under the action of a special device (not shown), the rocker arm 11, which fulfilled its main functions, are rotated around the axes 10 and rotated the axes 21 of the rocker arm 20 around the axes 21 through the number of cores assembled and the assembly process continues in the traditional way.
