Abstract
Provided is an explosion-proof suspension spot welding device, which is used for reducing failure rate of the device and guarantees personal safety of operators. The explosion-proof suspension spot welding device comprises a suspension spot welder. A compressed air interface of the suspension spot welder is connected to gas source through a welding machine solenoid valve. A cooling water inlet of the suspension spot welder is connected to a water inlet valve, and a cooling water outlet is connected to a water return valve through a flow detection switch. A normally closed contact of the flow detection switch controls the welding machine solenoid valve. With the arrangement of the flow detection to control the welding machine solenoid valve, the welding machine solenoid valve will not convey compressed air to the suspension spot welder when the cooling water flow does not reach to a set value. In this case, the suspension spot welder cannot work normally. The possibility that an outer insulation rubber pipe of a water-communicating cable due to the fault of a circulating water cooling system can be completely eliminated and personal safety of operators can be effectively protected.
Description
Technical field
The utility model relates to a kind of hitch point welder that is used to weld sheet metal component, belongs to metal machining tool technical field.
Background technology
Mash welder is the high-efficient welding equipment that two above sheet metal components (below the 3.5mm) are welded together.In mash welder when work, make the electrode workpiece pressing by compressed air, utilizes electric current to flow through the heat that the electrode adjacent domain produced and weld.In welding process, the Water cooling cable of mash welder, controllable silicon, transformer all can produce a large amount of heat, therefore need to use circulating water cooling system to cool off, and have only when cooling water flow reaches 3L/min, could obtain desirable cooling effect.Because existing hitch point welding machine does not all have cooling circulating water flow detection function; In case circulating water cooling system breaks down; Welding machine will move under the low excessively situation of cooling water or cooling water flow not having; Be easy to cause the explosion of Water cooling cable exterior insulation sebific duct like this, make operating personnel's personal safety receive serious threat.
The utility model content
The utility model be used to overcome above-mentioned prior art defective, a kind of hitch point welder with explosion prevention function is provided, to reduce rate of breakdown, guarantee operator's personal safety.
The alleged problem of the utility model realizes with following technical proposals:
A kind of hitch point welder with explosion prevention function; It comprises a hitch point welding machine; The compressed air interface of said hitch point welding machine is connected with source of the gas through the welding machine magnetic valve; The cooling water inlet of hitch point welding machine connects inlet valve, and coolant outlet takes back penstock through the flow detection switch, the normally-closed contact control welding machine magnetic valve of said flow detection switch.
Above-mentioned hitch point welder with explosion prevention function also comprises trouble lamp in the formation, an end ground connection of said trouble lamp, and the other end connects positive source through the normally opened contact and the hand switch of flow detection switch successively.
The utility model is provided with the flow detection switch and controls the welding machine magnetic valve by the flow detection switch on the cooling water circulation line; When cooling water flow does not reach setting value; The welding machine magnetic valve carries compressed air for the hitch point welding machine; Hitch point welding machine cisco unity malfunction causes the possibility of Water cooling cable exterior insulation sebific duct explosion with regard to thorough the elimination because of circulating water cooling system breaks down like this, thereby has effectively protected operator's personal safety.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to detail.
Fig. 1 is the structural representation of the utility model.
Each label is among the figure: 1, inlet valve; 2, backwater valve; 3, backwater water knockout drum; 4, water inlet water knockout drum; 5, flow detection switch; 6, ball valve; 7, compressed air valve; 8, filter; 9, pressure-reducing valve; 10, compressed air treatment device; 11, welding machine magnetic valve; 12, hitch point welding machine; L, trouble lamp; SB1, hand switch; SB2, flow detection switch normally opened contact; SB3, flow detection switch normally-closed contact.
The specific embodiment
Referring to Fig. 1; The utility model mainly is made up of inlet valve 1, backwater valve 2, flow detection switch 5, welding machine magnetic valve 11, hitch point welding machine 12, trouble lamp L, hand switch SB1; Compressed air treatment device 10 among Fig. 1 is used for filtering and adjusting compressed-air actuated pressure, and backwater water knockout drum 3 is used for distributing cooling water to a plurality of soldering turrets with water inlet water knockout drum 4.Flow detection switch 5 adopts SMC product I FW510-04-00 switches, and flow detection switch 5 converts water flow signal into the signal of telecommunication, is switching signal with analog signal conversion.
Before carrying out weld job, earlier inlet valve 1, backwater valve 2 and compressed air valve 7 are opened; The cooling water Automatic Cycle is cooled off soldering turret; The compressed air of source of the gas provides clean and the certain compressed air of pressure through filter 8 and pressure-reducing valve 9 for soldering turret, the pressure stability of electrode when guaranteeing welding; Backwater water knockout drum 3 is distributed to a plurality of soldering turrets with water inlet water knockout drum 4 with cooling water and is used; The use of a plurality of ball valves 6 in order to independent control recirculated water is installed respectively on each water knockout drum, and when hitch point welding machine 12 welded, flow detection switch 5 was connected in the cooling circulating water water return pipeline; Dispose normally opened contact SB2 and normally-closed contact SB3 in it; SB2 connects with trouble lamp L, and control trouble lamp L switches on and off, and SB3 connects with welding machine magnetic valve 11; The spool switching-over that switches on and off the control magnetic valve through SB3 realizes the control to the soldering turret gas circuit.When circulating cooling water flow when 3L/MIN is above, SB2 and SB3 are failure to actuate, trouble lamp L is in and extinguishes state, hitch point welding machine 12 normally uses; When circulating cooling water flow below 3L/MIN or cooling circulating water when not opening, SB2 connects the alarm lamp circuit, trouble lamp L flicker is warned, SB3 breaks off simultaneously, cuts off the magnetic valve loop and makes hitch point welding machine 12 stop action.
External air source provides the compressed air of 5Kg/cm2; Compressed air filters through filter 8 earlier, through pressure-reducing valve 9 decompressions, through oil sprayer air and oil gas is mixed at last again; Offer welding machine magnetic valve 11 and use, realize the weld job of hitch point welding machine 12 through the switching-over of welding machine magnetic valve 11.
The voltage that all electric elements use is DC24V, guarantees user's personal safety.SB1 belongs to hand control switch, is used to control the use of trouble lamp L, is in closure state when normally using, and when long-time stopping using, can close SB1.
