Abstract
The utility model provides a die structure of a press key board, which comprises an upper die seat, an upper clamping plate, an upper material removing plate, a guide pin and a lower die plate, wherein the upper clamping plate, the upper material removing plate and the lower die plate are arranged from top to bottom; the guide pin is fixed to the upper clamping plate and passes through the upper material removing plate; an inserting and pulling cushioning device of the guide pin is arranged between the upper material removing plate and the upper die seat; a lower die seat is provided with a double-purpose pin for floating and lifting; the double-purpose pin can upwards pull the upper die seat. The utility model can guarantee accurately positioning of the guide pin when used, guarantee to have no deformation of a material plate during work process and guarantee easy feeding and fluent production during production process.
Description
Technical field
The utility model relates to a kind of mould structure, particularly a kind of processing mold structure of wide cut thin material plate of material.
Background technology
The material thickness of punching press sometimes can be very thin in the time of in punching production, and width is bigger, and the feed distance of mould is also distant, and thickness is generally in 0.15 millimeter, and width is in 350 millimeter, feed distance 2000 millimeter.Existing wide cut thin material plate of material processing mold structure include upper bolster, train wheel bridge, on take off material, pilot pin, lower bolster, train wheel bridge, up stripper, lower bolster are arranged installation from top to bottom, pilot pin passes train wheel bridge.In punch process, upper bolster is with the pilot pin on it, the mechanical movement of doing vertical direction that up stripper is synchronous, pilot pin is fixed on the train wheel bridge, after upper bolster sinks, up stripper is pushed down plate of material earlier, pilot pin and then insertion plate of material, when upper bolster rose, up stripper broke away from plate of material, simultaneously, pilot pin is extracted out from plate of material, in the said process, because plate of material is thin, pilot pin causes the modification of material easily when inserting plate of material, cause the location inaccurate, and, when extracting plate of material, pilot pin is not easy to throw off with plate of material, cause plate of material to take up, therefore the correcting of plate of material when feeding is very difficult, has caused feeding to have some setbacks, and produces not smooth.
Summary of the invention
The purpose of this utility model provides a kind of novel wide cut thin material plate of material processing mold structure that can effectively overcome the problems referred to above generation, and its feeding is smooth, produces smooth.
The purpose of this utility model be achieved in that it include upper bolster, train wheel bridge, on take off material, pilot pin, lower bolster, train wheel bridge, up stripper, lower bolster are arranged installation from top to bottom, pilot pin is fixed on the train wheel bridge, pilot pin passes up stripper, and its improvement is: a pilot pin plug buffer unit is arranged between up stripper and the upper bolster.
In the said structure, pilot pin plug buffer unit is the spring assembly that connects between up stripper and the upper bolster.
In the said structure, the dual-purpose pin of the buoyance lift that upwards promotes upper bolster is arranged on the lower bolster.
Owing to adopted said structure, before up stripper was pushed down plate of material earlier, pilot pin freely inserted earlier plate of material, the accurate positioning of the pilot pin of assurance, when pilot pin is extracted, up stripper is pushed down material, extracts pilot pin earlier, and up stripper breaks away from material then, when being transferred to, pilot pin plate of material can not taken up, guaranteed that plate of material is indeformable, feeding is smooth in process of production, produces smooth.
Description of drawings
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is the structural representation of mould closure in the utility model wide cut thin material plate of material processing mold structure
The structural representation that Fig. 2 opens for mould in the utility model wide cut thin material plate of material processing mold structure
The specific embodiment
As shown in Figure 1, when upper bolster 250 beginnings are closed downwards, up stripper 210 touches the dual-purpose pin 240 of buoyance lift earlier, the dual-purpose pin 240 of buoyance lift upwards holds up and takes off plate 210, allow pilot pin 220 expose and take off plate 210 insertion plate of material, continue descendingly, up stripper 210 is done under the power contact at the pressure of patrix spring assembly 260 and is fallen plate of material 100 backs and continue descendingly, and up stripper 210 is pushed down plate of material 100.Before up stripper was pushed down plate of material earlier, pilot pin freely inserted plate of material, the accurate positioning of the pilot pin of assurance.
As shown in Figure 2, when upper bolster 250 begins upwards to open, upper bolster 250 takes up pilot pin 220 on it to up, on take off plate 210 and make under the power together upwards row at the upward pressure of the dual-purpose pin 240 of buoyance lift, after the dual-purpose pin 240 of up stripper 210 and buoyance lift separates, under the effect of up stripper 210 spring assembly 260 thereon, add that the effect of own wt breaks away from pilot pin 220 with plate of material 100.When pilot pin was extracted, up stripper was pushed down material, extracted pilot pin earlier, and up stripper breaks away from material then, plate of material can not taken up when pilot pin is transferred to, and had guaranteed that plate of material is indeformable.
Claims (3)
1, a kind of wide cut thin material plate of material processing mold structure, it include upper bolster, train wheel bridge, on take off material, pilot pin, lower bolster, train wheel bridge, up stripper, lower bolster are arranged installation from top to bottom, pilot pin is fixed on the train wheel bridge, pilot pin passes up stripper, it is characterized in that: a pilot pin plug buffer unit is arranged between up stripper and the upper bolster.
