Description

Multi-head efficient spot welding machine

Technical Field

The utility model relates to a welding machinery technical field, concretely relates to high-efficient spot welder of bull.

Background

Welding: also known as welding, meltallizing, is a process and technique for joining metals or other thermoplastic materials, such as plastics, by heat, heat or pressure. Welding accomplishes the purpose of joining by three ways:

1. fusion welding, namely heating the workpieces to be jointed to locally melt the workpieces to form a molten pool, and jointing the workpieces after the molten pool is cooled and solidified, wherein a melt filler can be added for assistance when necessary;

2. pressure welding-the welding process must apply pressure to the workpiece;

3. brazing, namely, a metal material with a melting point lower than that of the base metal is used as brazing filler metal, the liquid brazing filler metal is used for wetting the base metal, gaps are filled, and the liquid brazing filler metal and the base metal are mutually diffused to realize the link weldment.

The energy sources for modern welding are many, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic, among others. In addition to use in a factory, welding can be performed in a variety of environments, such as the field, underwater, and space. Wherever welding can be dangerous for the operator, appropriate precautions must be taken while welding is being performed. The possible injuries to human body caused by welding include burn, electric shock, visual impairment, toxic gas inhalation, over-irradiation of ultraviolet rays, etc.

The spot welder adopts the principle of double-sided double-point overcurrent welding, when in work, two electrodes pressurize a workpiece to enable two layers of metals to form a certain contact resistance under the pressure of the two electrodes, when welding current flows from one electrode to the other electrode, instant thermal welding is formed at the two contact resistance points, and the welding current instantly flows from the other electrode to the electrode along the two workpieces to form a loop, so that the internal structure of the workpiece to be welded can not be damaged during welding.

At present, weldment in the industry usually has a plurality of solder joints that need to weld, adopt manual mode to weld among the prior art usually, this kind of welding mode inefficiency, the spot welding process is by hand removal work piece, including the artificial uncertain factor of operator, can arouse the unstability of solder joint quality, at present along with spot welder's development, the mode of manual spot welding is replaced by spot welder gradually, spot welder's welding mode is to put the weldment on the welding frame, open spot welder and carry out spot welding, manual removal weldment after having welded, after the point alignment bonding tool that will weld next, continue to start welding, this kind of mode also exists inefficiency, artifical intensity of labour is big, the relatively poor grade shortcoming of solder joint quality.

Moreover, the welding head of the existing welding machine is less, when one workpiece needs to be welded at multiple positions, the working efficiency is low, and the welding can be finished by multiple times of welding.

Therefore, the equipment capable of completing the welding of a plurality of parts at one time is developed, the production efficiency can be effectively improved, and the practical significance is achieved.
