Description

Automatic multifunctional bull wire netting mash welder

Technical field

The utility model relates to welding equipment, the automatic multifunctional bull wire netting mash welder that a kind of spot welding that is used for wire nettings such as steel wire, stainless steel cloth of more clearly saying so is produced.

Background technology

The welding of existing steel wire series products is produced and is all used single point spot welder.Welding method is fixed on steel wire on the welding positioner (anchor clamps) by ad-hoc location earlier, uses the ground spot welding of a point of a point of single point spot welder then, until have a few and all welded, open mold (anchor clamps) at last, product is taken out.Bicycle use dress thing basket comes to this and produces, and welding chicken coop net, decoration website, protection planar steel wire screen also be to produce like this.Aforementioned production method is time-consuming, and labour intensity is big, production efficiency is low, and because of the little quality that do not guarantee of chucking power of anchor clamps, defectives such as weldering, rosin joint occur leaking unavoidably.The production equipment that large-scale welding wire plain net is abroad arranged, the automaticity height, the production efficiency height, quality might as well.But it costs an arm and a leg, and is difficult to popularize in small-sized or individual enterprise.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of production efficiency height, labour intensity is low, welding quality good, and low price, the automatic multifunctional bull wire netting mash welder that is easy to popularize.

Summary of the invention

In order to achieve the above object, the utility model by body, one group of top electrode being installed in welding transformer in the body, being installed in electric control panel on the body, link to each other and one group of bottom electrode, be installed in the body at steel wire feeding between the two arrays of electrodes and mesh specification guiding mechanism up and down and electrode pressure lever that electrode is pressed on the steel wire and constituted with welding transformer secondary.The electrode pressure lever can footboard drives.Welding transformer have in parallel about two, parallel installation.Its secondary coil upper end is connected with top electrode with last conductive plate with annular conductive strips.The lower end is connected with bottom electrode with lower conducting plate.Secondary coil and annular conductive strips, last conductive plate and lower conducting plate form ring-type.About two parallel installations of welding transformer, help the balance and stability of complete machine, and reduce noise.The quality of product also increases because of alleviating vibration.Annular connects electricity and makes that the secondary contact everywhere of this machine well contacts, stable working, has alleviated vibration, thereby has prolonged the service life of welding machine.Also have a single head point soldering tip on the body.It is by the free bearing that is fixed on the body, be hinged on going up the weldering arm and welding arm down on the free bearing with hinge, be fixed on down the support of weldering below the arm, be fixed on down on the weldering arm and the bottom electrode that insulate on every side and be connected with welding transformer secondary coil one end, be installed in the top electrode cover of the insulation on the weldering arm, be installed in the top electrode cover and the top electrode that is connected with the welding transformer secondary coil other end, being hinged on top electrode set upper side and rear end is hinged on the single head pressure lever on the pillar and is fixed on the pillar of weldering on the arm and constitute.Single head point soldering tip makes this machine one-machine-multi-function, but except that regular lot, make up a deficiency the steel wire site fast, also can be used for steel plate, steel wire single-piece, reaches the production, maintenance etc. of odd jobs in small batches, and is very convenient.During use,, top electrode interlocked with top electrode depress, get final product spot welding with manual control single head pressure lever.Single head point soldering tip can turn round around hinge 180 degree, and is to select suitable operating position, convenient, flexible.

Steel wire feeding and mesh specification guiding mechanism are by the hydraulic system that is installed in the body, with hydraulic pressure system moving drive send section's oil cylinder, the tooth bar that the piston rod of feeding oil cylinder has, with the tooth bar meshed gears, be sleeved in the centre bore of gear the main oil that can freely rotate relative to gear, be connected in ratchet on the main shaft with key, be installed on the piston rod and withstand on ratchet and reduction torsion spring thereof on the ratchet, be fixed on the sprocket wheel on the main shaft, be installed in the chain on the sprocket wheel, be fixed on the steel wire clamp that has the transverse steel wire groove on the chain and be fixed on a row who is used to pass vertical steel wire on the body and vertically wear a mould and form.Also have locating piece on the piston rod.Have on the body can adjusting position so that the block of piston rod extended position location.Sprocket wheel and chain respectively have 2～5 covers.

Pierce into by hand steel wire is longitudinally worn a mould earlier, and with manual positioned in alignment.Transverse steel wire is put into the transverse steel wire groove, when horizontal, the vertical steel wire of general is spot-welded together, primer fluid pressing system---feeding oil cylinder.When piston rod stretches out, driven gear, ratchet, ratchet, main shaft, sprocket wheel, chain, the feeding of steel wire clamp successively, the distance of its steel wire length feed is by the determining positions of block.Piston rod is return when resetting, and ratchet slides on ratchet, and gear dallies on main shaft.Accordingly, put into the transverse steel wire steel wire clamp of some at interval of the transverse steel wire groove of steel wire clamp.Therefore, the motion of piston rod promotion ratchet, sprocket wheel, chain is intermittent movement.In the time of intermittently, finish spot welding.The adjusting of horizontal spacing is by at a certain distance from vertically wearing vertical steel wire decision that a mould passes.The utility model production efficiency improves 28～32 times, economical with materials 15～25%, and the steel wire mesh is easy to adjust.It can be widely used in the spot welding production of woven wires such as stainless steel cloth, steel wire.
