Preferably, rotation fixing axle 3 is fixed on by support column 2 on lower bottom base.
Preferably, rotation fixing axle is fixed with dial, and the rotation portion for rotating fixing axle is equipped with and coordinates with dial Indicator, i.e. indicator are mounted on rotating part.
Preferably, upper holder block 7, lower lock block 5 and saw blade contact position are elastic material, and saw blade is diamond disc 8.
Preferably, elastic material is rubber.
Preferably, rotation fixing axle includes the fixed part (i.e. support column) being fixed on lower bottom base, is movably fixed to fixation Rotating part in portion, saw blade are set on rotating part, and dial is fixed on fixed part, and indicator is fixed on rotating part, Fixed part is support column.
It is connected by bearing between fixed part and rotating part.
Mash welder system uses the principle of double-sided double-point over-current welding, and two electrodes pressurization workpiece make double layer of metal exist when work Form certain contact resistance under the pressure of two electrodes, and welding current when flowing through another electrode from an electrode in two contact resistances Point forms the thermal welding of moment, and welding current moment flow to this electrode forming circuit from another electrode along two workpiece, and not The internal structure of welded piece can be injured.
Mash welder has universal (general-purpose type), specialized type according to purposes point;According to the solder joint number point of welding simultaneously, have Single-point type, kinds of point mode, multipoint mode;It is having unilateral side, bilateral according to electrically conducting manner point;Divide according to the kind of drive of pressing mechanism, There are foot-operated, motor-cam-type, vapour-pressure type, fluid pressure type, combined type (Gas fluid pressure is box-like);According to the characteristic point of operating, have non- Automation, automation;According to the method point of installation, have it is fixed, it is mobile or portable (suspension type);According to the activity of welding machine The moving direction of electrode (being commonly top electrode) point, there is vertical stroke (electrode is for linear motion), circular arc stroke;According to electric energy Supply mode point, have power frequency welding machine (using 50 hz AC power supplys), pulsating welder (DC pulse welding machine, percussion welder etc.), Frequency conversion welding machine (such as low frequency welder).
When one timing of workpiece and electrode, the resistance of workpiece depends on that with its resistivity, therefore resistivity is materials to be welded Its good conductivity (such as aluminium conjunction of the low metal of its poorly conductive (such as stainless steel) resistivity of the high metal of important performance resistivity Gold).Therefore, when spot welding stainless steel heat production easily and radiate it is difficult, when spot welding aluminium alloy heat production it is difficult and radiate easy spot welding when, Qian Zheke With smaller current (a few kiloamperes), and the latter must just use very high current (tens of thousands of amperes).Resistivity not only depends on and metal kind Class, it is also related with the condition of heat treatment of metal, processing method and temperature.
In order to ensure that nugget size and Joint Strength, weld interval in a certain range can be mutually complementary with welding current It fills.In order to obtain the solder joint of some strength, high current and short time (strong condition, also known as hard specification) may be used, can also be used Low current and long-time (weak condition, also referred to as soft specification).Hard specification or soft specification are selected, performance, the thickness of metal are depended on With the power of welding machine used.Electric current needed for metal for different performance and thickness and time, all there are one bounds, use When take this as the standard.
Electrode pressure all-in resistance R between two electrodes has apparent influence, and with the increase of electrode pressure, R is substantially reduced, and The increased amplitude of welding current is little, cannot influence the heat production caused by R reduces and reduce.Therefore, Joint Strength is always with weldering Pressure is connect to increase and reduce.Solution is increase of weld current while increasing welding pressure.
