Technical field
The utility model relates to a kind of cupping tool, especially relates to the adjustable general cupping tool of a kind of simple and easy pressure-pad-force.
Background technology
Pull and stretch is an important process in the sheet-metal press working field, he automobile, instrument and meter, electronics, life day industry such as product use in a large number, often relate in the deep-drawing technique and breaking and wrinkling two big quality problems, the way of its solution is the suitable pressure-pad-force of employing.At present pressure-pad-force produces and generally adopts flexible member and hydraulic die cushion, or transformation limit device, and former structure is simple, but power increases with the increase of stroke, causes easily breaking, and latter's pressure-pad-force can be regulated, but complex structure, the die cost height.If when sheet thickness variation or small lot trial-production, will cause cost to increase greatly, the die trial cycle increases.
The utility model content
The purpose of this utility model is exactly to provide a kind of simple in structure, easy to use for the defective that overcomes above-mentioned prior art existence, and the adjustable general cupping tool of simple and easy pressure-pad-force easy to replace and maintain.
The purpose of this utility model can be achieved through the following technical solutions: the adjustable general cupping tool of a kind of simple and easy pressure-pad-force, it is characterized in that, this mould is mainly by the part of the upper die, the part of the lower die, flanging is partly formed, described part of the upper die comprises die shank, upper clamping plate, guide pin bushing, backing plate, punch retainer, punch, described die shank is connected with upper clamping plate, described guide pin bushing is arranged on the upper clamping plate both sides, described backing plate is connected with upper clamping plate, described punch retainer is connected with backing plate, described punch is connected with punch retainer, described part of the lower die comprises the counterdie seat board, the die backing plate, following latch segment, die plate insert, die block, guide pillar, described die backing plate is arranged on the counterdie seat board, described die block is connected with the die backing plate, described die plate insert is connected with die block, described guide pillar is arranged on counterdie seat board both sides, be slidingly matched with guide pin bushing, described flanging partly comprises blank holder, last latch segment, handle, the described latch segment of going up, handle is threaded with blank holder.
Described part of the upper die comprises the spline pin, and this spline pin is arranged on the junction of die shank and upper clamping plate.
Described die shank is connected with the upper clamping plate interference fit.
Described punch is connected with the punch retainer interference fit.
Described part of the upper die also is provided with suspension ring, and described flanging part is connected with suspension ring by chain.
Described flanging partly is provided with latch segment, and the part of the lower die is provided with down latch segment, and described flanging part also is provided with and can screws in and regulate the handle of pressure-pad-force.
Compared with prior art, the utility model had both solved the problem that the cupping tool in the past produced can only a kind of thickness of slab of pull and stretch, also can guarantee the controllability of pressure-pad-force, punch and die adopt insert structure simultaneously, easy to replace and maintain, to adapt to the pull and stretch production of different-thickness and size.
Description of drawings

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1 and Figure 2, the adjustable general cupping tool of a kind of simple and easy pressure-pad-force, this mould mainly partly is made up of part of the upper die, part of the lower die, flanging, and the part of the upper die is made up of die shank 1, spline pin 2, upper clamping plate 3, suspension ring 4, guide pin bushing 5, backing plate 7, punch retainer 8, punch 9.Die shank 1 and upper clamping plate 3 interference fit, and fixing by spline pin 2.Backing plate 7, punch retainer 8 are connected on the upper clamping plate 3 by soket head cap screw, and locate by pin.Punch 9 and punch retainer 8 interference fit, guide pin bushing 5 is arranged on upper clamping plate 3 both sides.Suspension ring 4 are arranged on the upper clamping plate 3.
The part of the lower die is made up of counterdie seat board 16, die backing plate 15, following latch segment 14, die plate insert 13, die block 12, guide pillar 6.Die backing plate 15, counterdie seat board 16 and die block 12 are connected the pin location by soket head cap screw.Die block 12, die backing plate 15 connect by soket head cap screw.Following latch segment 14 is fixed on the die block 12 by soket head cap screw.Die plate insert 13 is connected with die block 12.Guide pillar 6 is arranged on counterdie seat board both sides, and this guide pillar 6 is connected with guide pin bushing 5.
