As preferably, described drift is fixedly connected with upper padding plate by gim peg.
Compared with prior art, usefulness of the present utility model is: the punching press requirement reaching Rockwell 40 ° after the drift of this stair step carrier bar essence punching die can meet carrier bar heat treatment, by traditional pulling eye, hit hole and Vehicle Processing three process boil down to one procedure, improve production efficiency, and the diplopore spacing tolerance on carrier bar can control within ± 0.02mm, the straight wall of hole wall reaches more than 85%, improves machining accuracy.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model stair step carrier bar essence punching die structure schematic diagram;
Fig. 2 is link plate structure schematic diagram.
In figure: 1, patrix frame plate; 2, upper padding plate; 3, upper mounted plate; 4, stripper; 5, contour unloading bolt; 6, drift; 7, gim peg; 8, guide bracket; 9, spring; 10, counterdie frame plate; 11, locating piece; 12, adjustable bolt; 13, slug hole; 14, carrier bar; 15, pilot hole.
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of stair step carrier bar essence punching die shown in Fig. 1, be made up of upper die component and lower mold assemblies, described upper die component comprises patrix frame plate 1, and patrix frame plate 1 top is connected with punch press, and bottom is disposed with upper padding plate 2, upper mounted plate 3 and stripper 4 from top to bottom; The center of described upper padding plate 2 and upper mounted plate 3 is provided with through hole, is provided with spring 9 in through hole, the two ends up and down of described spring 9 respectively with patrix frame plate 1 and stripper 4 inconsistent; The bottom of described upper padding plate 2 is provided with two drifts supported by PM HSS 6 and a guide pillar 8, described drift 6 is arranged on the both sides of spring 9, be fixedly connected with by gim peg 7 between its with upper padding plate 2, described guide pillar 8 is positioned at the outside of a wherein drift 6, the end of described drift 6 and guide pillar 8 runs through upper mounted plate 3 and stripper 4, and the end of guide pillar 8 extends to the outside of stripper 4; Have gap between described stripper 4 and upper mounted plate 3, stripper 4 is connected with patrix frame plate 1 with upper padding plate 2 through upper mounted plate 3 by contour unloading bolt 5; Described lower mold assemblies comprises counterdie frame plate 10, and counterdie frame plate 10 is fixedly installed on work bench of punch press, and its top is provided with two and sees accompanying drawing 2 for installing carrier bar 14() locating piece 11 and and the pilot hole 15 that match corresponding with guide pillar 8; Described locating piece 11 is flexibly connected with counterdie frame plate 10 by adjustable bolt 12, the counterdie frame plate 10 between two pieces of locating pieces 11 is provided with two slug holes 13, and this slug hole 13 is corresponding with drift 6.
Its concrete occupation mode is as follows, according to the size of carrier bar 14, regulate locating piece 11, then carrier bar 14 is placed between locating piece 11, then punch press switch is started, patrix frame plate 1 drives the upper padding plate 2 below it, upper mounted plate 3 and stripper 4 move down, guide pillar 8 steadily enters in pilot hole 16, then stripper 4 is spacing by locating piece 11, patrix frame plate 1, upper padding plate 2 and upper mounted plate 3 drive drift 6 to continue to move down, for there is gap between stripper 4 and upper mounted plate 3, and counterdie frame plate 10 is provided with slug hole 13 that is corresponding with drift 6 and that coincide, therefore drift 6 can continue to press down after contact carrier bar 14, the waste material that carrier bar 14 is gone out falls in the slug hole 13 on counterdie frame plate 10 by drift 6, after punching press completes, stripper 4, upper mounted plate 3, upper padding plate 2 and patrix frame plate 1 backhaul, because carrier bar 14 is easily stuck in backhaul together on drift after drift 6 punching press, therefore in return stroke, because stripper 4 is by spring 9 resilience downwards, and drift 6 follows upper padding plate 2 to continue backhaul, once after the end of drift 6 enters stripper 4, the carrier bar 14 be stuck on drift 6 will be backed off by stripper 4, complete discharging, then carrier bar 14 is taken out.
The punching press requirement of Rockwell 40 ° is reached after the drift 6 of this stair step carrier bar essence punching die can meet carrier bar heat treatment, by traditional pulling eye, hit hole and Vehicle Processing three process boil down to one procedure, improve production efficiency, and the diplopore spacing tolerance on carrier bar 14 can control within ± 0.02mm, the straight wall of hole wall reaches more than 85%, improves machining accuracy.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
