The processing of metal sheet metal work often uses mould collocation punch press to carry out, and then can select the collocation of the feeder and the progressive die to use when needing a large amount of productions or high-speed production.When making the metal sheet metal work, the size of workpiece is to utilize the location of mould to realize, so mould collocation punch press product or the workpiece produced, is the finished size of workpiece.When if the operation that the workpiece that machines continues is welding procedure; Then need one group of tool of otherwise designed to carry out the location of workpiece; Just can execute and weld, but when workpiece has the bending machining or the design of circular arc camber, phenomenons such as workpiece easy generating material resilience problem or distortion; Cause workpiece to put into the difficulty of tool or influence the location of workpiece, cause the position degree generation quality problems of welding.
Summary of the invention
In order to solve above-mentioned technical problem; The purpose of this invention is to provide a kind of blanking die, take punching process and welding procedure to combine, electrode is set to one group of drift in the middle of the progressive die;, strip begins punch forming after getting into the progressive die; When the workpiece of semifinished or finished goods arrives the position of welding electrode, utilize the closed strength of punch press bolster, control power-on and power-off cartridge produces suitable pressure to the position that workpiece need weld; And start the welding switch and directly weld, reach the effect of continuous punch forming and continuous welding.Utilize present technique, workpiece need not reorientated, and can effectively stablize workpiece size, and moulding and welding once accomplish, and can effectively save pitch time, significantly reduces production costs.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of blanking die; Comprise lower bolster and cope match-plate pattern; Said lower bolster is provided with bottom electrode; Said cope match-plate pattern is provided with the top electrode that when matched moulds, can cooperate the elasticity clamping work pieces with bottom electrode, and said lower bolster or cope match-plate pattern are provided with the welding switch that when matched moulds puts in place, can be triggered, and said bottom electrode, top electrode and welding switch all are connected with the welding main frame.Move down when arriving the workpiece welding position because the action of punch press is driven by cope match-plate pattern when top electrode; Upper and lower electrode pair workpiece weld produces suitable pressure, and weld switch and be triggered this moment, and the welding main frame is seen electric current off; Workpiece executed weld, accomplish weld job.Punch press continues running, and cope match-plate pattern drives top electrode and moves up, and gets back to original position, and strip is pushed ahead, and circulation continues to produce.
As preferably, said lower bolster or cope match-plate pattern are provided with the strip sensor, and the strip sensor is connected with the welding main frame.Only when detecting strip, just start the welding main frame, empty weldering takes place in the time of can avoiding not having workpiece like this.
As preferably, said lower bolster and cope match-plate pattern all are installed on the punch press through insulation board.
As preferably, said bottom electrode comprises the lower electrode holder of insulation, and bottom electrode body is installed in above the lower electrode holder, and the bottom electrode head is installed on the bottom electrode body, bottom electrode body via the bottom electrode conductive copper plate with weld main frame and be connected.
As preferably, said bottom electrode head is the replaceable type electrode tip.Be convenient to change when consume takes place.
As preferably; Said top electrode comprises the top electrode seat of insulation; The top electrode body is installed in below the top electrode seat, vertically is inserted with the cartridge that powers on the top electrode body, and the cartridge that powers on is connected with the top electrode seat through spring; The top electrode body is connected with the welding main frame via the top electrode conductive copper plate, and said welding switch is the start sensor that is installed on the top electrode seat.The pressure that through the poundage design scalable electrode that spring is set workpiece is produced like this, when the cartridge that powers on was compressed to desired location via spring, the welding main frame just can start the supply electric current.
As preferably, the said cartridge that powers on is the replaceable type electrode tip.Be convenient to change when consume takes place.
The present invention is owing to adopted above technical scheme; Can the arrange in pairs or groups continuous production of punch press of the progressive die be combined with welding procedure; Utilize the punching press running of punch press to make the electrode pair workpiece produce the strength that compresses, carry out the continuous production of punching press and welding, use identical location can effectively increase the stability of product size; Two kinds of technologies combine the continuous production of running to reduce production costs, and enhance productivity.
