Abstract
The utility model relates to a capacitor-discharge type spot welding machine, which mainly comprises a transformer, a bridge rectifier, a capacitor bank and the like. The transformer is a voltage regulating transformer with a voltage regulating range between 0V and 220V, the capacitor bank consists of a bank of parallelly connected electrolytic capacitors identical in capacity, and a typical parameter of each capacitor is 160V, 2200uF. When the capacitor-discharge type spot welding machine is used, objects to be welded are connected to a positive binding post and a negative binding post of an output end of the spot welding machine through leads, and according to different conditions of the objects to be welded, the number of the capacitors serially connected into a circuit is controlled by capacitor buttons so that discharge energy is changed, and spot welding between the objects to be welded can be realized through charge-discharge of the capacitors. The capacitor-discharge type spot welding machine is simple in structure and capable of performing spot welding of metal materials quickly, conveniently and firmly.

Technical field
The utility model belongs to welding technology field, relates to a kind of mash welder, particularly a kind of capacitor-discharge spotwelder.
Background technology
Mash welder price in the market is generally higher, and can not satisfy some spot welding needs in particular cases.For example, in the very little metallic cavity of diameter,, be difficult to weld owing to receive the restriction of welding condition so that measure the inside cavity temperature by welding one thermocouple with existing mash welder.
Summary of the invention
The technical problem that the utility model will solve provides a kind of simple and practical, mash welder of being fit to multiple welding condition.
In order to solve the problems of the technologies described above, a kind of capacitor-discharge spotwelder of the utility model mainly is made up of transformer, rectifier bridge heap and capacitor group.But said transformer is an adjustable transformer, and range of regulation is between 0-220V; Said capacitor group is made up of the electrolytic capacitor parallel connection of one group of same capability, and the canonical parameter of capacitor is 160V, 2200uF.During actual the use; Welding object is wired to the positive and negative binding post of mash welder output respectively; Different situations according to welding object; The capacitors count of controlling parallelly connected place in circuit through capacitive buttons is to change discharge energy, through the spot welding that realizes between welding object that discharges and recharges of capacitor.
The utility model is owing to adopt above-mentioned design, and it is simple in structure, can carry out the spot welding of metal material fast, conveniently, securely.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the sketch map of a kind of capacitor-discharge spotwelder of the utility model.
Fig. 2 is the circuit diagram of a kind of capacitor-discharge spotwelder of the utility model.
Among the figure: 1. total power switch, 2. transformer, 3. adjusting pressuring knob, 4. charge switch; 5. rectifier bridge heap, 6. voltmeter, 7. capacitor group, 8,9,10. capacitive buttons; 11. the spot welding button, 12. output positive terminals, 13. output negative terminals, 14. power line sockets.
The specific embodiment
Like Fig. 1, shown in Figure 2, the 220V alternating current after rectifier bridge is piled 5 rectifications, is carried on the capacitor group 7 through adjusting pressuring knob 3 pressure regulation of transformer 2 again, and capacitor group 7 is by big capacity electrochemical capacitor C
