Description

Spring bearer plate blanking die
Technical field
The utility model relates to a kind of stamping and blanking mode structure, is specially a kind of spring bearer plate blanking die.
Background technology
Cold stamping occupies very consequence in forging and stamping are produced, application is in the industry very extensive, Cold Press Working is at normal temperatures, utilize the pressure of forcing press, processed by the material of cold-punching mould to various different specification size, make the part of required shape and size, the process of stamping-out is the process be separated with another part material by a part of material of metal or nonmetal plate, mould has been a kind of specific purpose tool of stamping procedure, is indispensable technological equipment at punching production scene.
A kind of mould conventional in blanking die industrial production, the workpiece processed in tradition blanking die is placed in the gap of stripper and die to be processed, when processing work, because stripper maintains static, gap is there is with stripper above workpiece, the workpiece adopting this kind of Mould Machining to go out can produce the phenomenon of surface irregularity, and the crudy of workpiece is poor.
Utility model content
The utility model is intended to provide one to ensure workpiece surface quality, and structure is simple simultaneously, lower-cost spring bearer plate blanking die.
Spring bearer plate blanking die in this programme, comprise upper mould part and lower mould part, upper mould part comprises die shank and punch, die shank is connected with external pressure machine, die shank overcoat has upper bolster, punch retainer is provided with below upper bolster, punch retainer is connected with punch, lower mould part comprises die shoe, die shoe top is provided with die, die has material-dropping hole, die shoe has discharge opening, also comprise spring bearer plate parts, spring bearer plate parts comprise unloading bolt, unloading bolt is divided into smooth section and thread segment, unloading bolt smooth section is successively through upper bolster and punch retainer, unloading bolt thread segment is provided with stripper, stripper is provided with the pilot hole moved up and down for described punch, upper bolster and punch retainer can move up and down along described unloading bolt smooth section, unloading bolt smooth section is also provided with discharging spring, offset on the downside of discharging spring one end and punch retainer, offset on the upside of the other end and stripper, punch and die are before matched moulds, punch is no more than place plane on the downside of stripper.
The operation principle of the spring bearer plate blanking die in this programme is: when needs carry out punch process to workpiece, first workpiece is positioned in mould, under the drive of outside forcing press, upper mould part and spring bearer plate parts move downward, punch moves up and down under the effect of stripper pilot hole, when stripper move downward touch surface of the work time, because punch was no more than place plane on the downside of stripper before matched moulds, now punch not yet touches surface of the work, under the lasting drive of outside forcing press, stripper position remains unchanged, upper bolster and punch retainer move downward along unloading bolt, owing to offseting on the downside of discharging spring one end and punch retainer, offset on the upside of the other end and stripper, now discharging spring will compress downwards, discharging spring-compressed produce elastic force through stripper for surface of the work provides a pressure-plate-force, surface of the work is made to keep smooth, external pressure machine continuation effect, punch touching surface of the work under the acting in conjunction of punch and die, workpiece is punched into desired structure, stamping is pushed out from die shoe discharge opening through die material-dropping hole, punch backhaul, the workpiece of hoop on punch is removed under the effect of stripper, workpiece is pushed ahead, blanking work continues.
The beneficial effect of the spring bearer plate blanking die in this programme is: by the setting of spring bearer plate parts, make workpiece before processing stripper provide a pressure-plate-force for workpiece, thus the smooth of surface when making work pieces process, can be ensured, improve the surface quality of processing work.
Further, die is provided with hook-type pin stop, hook-type pin stop head exceeds on the upside of die, can be used for positioning workpiece feed direction, due to the hook design that hook-type pin stop is special, the edge of a knife of pin-and-hole away from die of this hook-type pin stop of installation can be made, thus effectively can ensure the intensity of die, improve the service life of die.
Further, be also provided with the backing plate for disperseing punch transmission of pressure between upper bolster and punch retainer, the pressure of punch transmission can disperse by backing plate, thus prevents punch crush injury upper bolster, improves the mold use life-span.
Further, lower mould part also comprises and is positioned at die top for guiding the stock guide of workpiece, and under the acting in conjunction of stock guide and hook-type pin stop, workpiece is placed on correct position, ensure that the crudy of workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: die shank 1, upper bolster 2, backing plate 3, punch retainer 4, punch 5, hook-type pin stop 6, die 7, lower bolster 8, stock guide 9, stripper 10, discharging spring 11, unloading bolt 12.
Embodiment substantially as shown in Figure 1, spring bearer plate blanking die, comprise upper mould part, lower mould part and spring bearer plate parts, upper mould part comprises die shank 1, upper bolster 2, pad 3, punch retainer 4 and punch 5, lower mould part comprises hook-type pin stop 6, die 7, die shoe 8 and stock guide 9, and spring bearer plate parts comprise stripper 10, discharging spring 11 and unloading bolt 12.
