Brazed plate heat exchanger fully-automatic sheet making system

Abstract

The present invention relates to a brazed plate heat exchanger fully-automatic sheet making system, comprising an intermediate frequency spot welding device (4) and two unwinding devices (5), whereinstainless steel plates and copper foil are wound around the two unwinding devices (5), respectively; the composite stainless steel plate and copper foil is introduced into an automatic length determining device (3) through the intermediate frequency spot welding device (4); and a mechanical arm assembly (1) is located next to a stamping device (2) and the automatic length determining device (3). The brazed plate heat exchanger fully-automatic sheet making system helps to improve operation efficiency and has high reliability.

Description

technical field [0001] The invention relates to a fully automatic sheet making system, in particular to a system for preparing sheets used in the manufacturing process of brazed plate heat exchangers. Background technique [0002] At present, in the production process of brazed plate heat exchangers, it is necessary to use a press to press out flow channels on the plates, and then stack the plates in turn to leave the factory; before pressing, it is necessary to compound copper foil as a solder on stainless steel After cutting and pressing, in order to avoid the separation of copper foil and stainless steel plate in the subsequent process, it is necessary to use spot welding machine to spot weld them at the edge, so as to avoid subsequent separation. Nowadays, the conventional spot welding method is to install a compression mechanism, and install the spot welding machine on both sides of the compression mechanism, and then perform spot welding, which lacks synergy between th...

AI Technical Summary

Problems solved by technology

Nowadays, the conventional spot welding method is to install a compression mechanism, and install the spot welding machine on both sides of the compression mechanism, and then perform spot welding, which lacks synergy between the two; each time the copper foil or stainless steel roll is changed , the spot welding machine must be removed first, and then the pressing mechanism should be released to change the roll. When the new roll is replaced, it must be pressed again and the position of the spot welding machine must be adjusted, which greatly affects the operating efficiency and is not conducive to improving Enterprise capacity

[0003] At the same time, before pressing the plate after spot welding, it is necessary to cut the plate into a suitable size and then cut it; the conventional fixed-length device uses a stepping motor to drive the conveying roller at regular intervals, that is, to convey a certain length at regular intervals. Stop driving the conveying roller after cutting the plate, and then the cutter performs cutting function; this method requires high precision of the stepping motor used for driving, and lacks corresponding defense measures. Once the motor drives a mistake, the fixed-length failure will occur

[0004] Finally, there are often two types of problems in the process of pressing and demoulding: one is sticking to the upper template, which is not easy to remove the material; Greatly delayed production efficiency
