To achieve these goals, the utility model adopts following technical scheme:
A kind of piercer; Comprise cope match-plate pattern, lower bolster, drift, said cope match-plate pattern is provided with several pilot holes, and lower bolster is provided with the following hole corresponding with pilot hole; Drift and pilot hole matched in clearance; Said drift comprises jumper bar and bar tail, and the radial dimension of bar tail is greater than the radial dimension of jumper bar, and said jumper bar is provided with around the movable elastic portion that cooperates of jumper bar and jumper bar.Elastic portion can be spacing ring and the compression spring between the bar tail that is limited on the jumper bar, high elastic rubber tube, or the combination tube of metallic gasket and high elastic rubber; The setting of elastic portion, when receiving impulsive force or pressure on the drift, elastic portion can be compressed, and drift just can impact workpiece, punctures the workpiece back punching head and stretches into down the hole, and punching is accomplished on the workpiece; After punching was accomplished, because of the screen resilience of elastic portion, drift can bounce back in the pilot hole of cope match-plate pattern, and drift separates with workpiece and following hole, and operation is very easy, and efficient is high, and punching quality is good.
As preferably, said elastic portion is the polyurethane rubber tube.Polyurethane rubber is polymerized by polyester (or polyethers) and two different eyeball acid esters compounds, and good springiness, oil resistant, anti-solvent are simple in structure, easy to carry, durable, and basic noise-less pollution when using.
As preferably, said hole down is up-small and down-big taper shape.Conical down hole makes things convenient for the whereabouts of waste material after the workpiece punching, guarantees punching quality, improves punching efficient; Need not to come the waste discharge material for lower bolster is provided with support, structure is simpler.
As preferably, the avris that leaves pilot hole of cope match-plate pattern and lower bolster is provided with at least 2 locating holes, is provided with the alignment pin that is used for cope match-plate pattern and the superimposed location of lower bolster in the locating hole.The setting of locating hole and alignment pin makes things convenient for the location of cope match-plate pattern and lower bolster, and punching is aimed at convenient, and the bolster held stationary can not move each other during punching, improves punching efficient, guarantees punching quality.
As preferably, the avris that leaves pilot hole of cope match-plate pattern and lower bolster also is provided with bolt hole, is provided with the adjusting bolt that connects cope match-plate pattern and lower bolster in the bolt hole.Regulate bolt and can be fastenedly connected bolster on the one hand; Workpiece can be clamped between the bolster, and on the other hand, regulating bolt can be according to the thickness adjusted cope match-plate pattern of workpiece and the spacing of lower bolster; Guarantee that bolster is stable to the clamping of workpiece, guarantee the punching quality of different-thickness workpiece.
As preferably, said adjusting bolt is provided with semicircular handle.Semicircle is conveniently held, and is convenient to regulating the bolt operation.
As the another kind of selection scheme of above-mentioned preferred version, said adjusting bolt is provided with the handle of annular.Cirque structure is conveniently held the adjusting bolt on the one hand and is operated, and on the other hand, when piercer moved, guided and supported the aspect.
As preferably, the end of said bar tail is provided with rubber cap.Reduce the noise that produces because of punching press in the piercer punching, also protect drift simultaneously, prolong drift service life.
Therefore, the utlity model has following beneficial effect: (1) is provided with elastic portion, and drift can be rebounded after the workpiece punching is accomplished automatically, drift and workpiece and down the hole separate, easy to operate efficient, punching quality is good; (2) up-small and down-big taper shape is arranged in the hole down, makes things convenient for the waste discharge material; (3) regulate bolt and establish the annular handle, simple in structure, convenient moving guided and supported.
