UN-8半自动锯条闪光对焊机

TUN-8半自动锯条对焊机是一种具有程序控制的闪光焊接设备，是带锯条生产必不可少的设备之一，具有焊接、退火之间程序自控，顶锻压力、焊接电压、退火温度、退火时间等外部可调节等功能，适用于普通钢带、高合金钢带、各类带锯条和带刀的对焊，焊接定位精确，操作方便，焊接牢靠，退火后硬度适当，质量可靠，不需要任何焊剂。

原理简述：

本机是根据电热效应的原理，利用连接到变压器次级两端的焊台，使夹持在两焊台上的锯条两端接触形成闭合回路。电流接通后，由于接触点上的电阻和电流密度都很大，金属被迅速加热溶化，并以连续激烈的火花状炸裂，构成整个熔化过程，在此同时由于受顶锻力的作用，焊机夹头以一定规律送进焊件，并适时切断电源，已溶化的金属从焊区挤压出，使焊件溶为一体，从而获得优良的焊体。

TUN-8 semi-automatic saw blade welding machine is a kind of program-controlled flash welding equipment. It is one of the indispensable equipment for the production of band saw blade. It has the functions of self-control between welding and annealing, forging pressure, welding voltage, annealing temperature, Annealing time and other external adjustable function for ordinary steel, high alloy steel, with all kinds of band saw blade and knife butt welding, welding positioning accuracy, easy to operate, reliable welding, the appropriate hardness after annealing, reliable quality, not Requires any flux.

Brief description of the principle:

This machine is based on the principle of electrothermal effect, using the soldering station connected to both ends of the transformer secondary, so that the two ends of the saw blade clamped in the two ends of the contact form a closed loop. After the current is switched on, the resistance and current density at the contact point are large, the metal is quickly heated to melt, and continuous intense spark-like burst to form the entire melting process, at the same time due to the role of forging force, welding Machine chuck to a certain law into the weldment, and timely cut off the power, the molten metal has been extruded from the welding area, so that pieces dissolved as a whole, in order to obtain good welding body.
