Description
Technical field
The utility model belongs to the big-and-middle-sized interior outer covering piece Trimming Die technical field of automobile, relates in particular to a kind of covering Trimming Die.
Background technology
Along with the develop rapidly of auto industry, people require more and more higher for the product quality of automobile panel, and auto-producing automaticity is more and more higher.For adapting to automation and high-quality requirement, must use the deburring waste knife without impact on product surface.The patrix waste knife adopting in big-and-middle-sized automobile covering trimming process and patrix edge iron piece are stepped ramp type, patrix waste knife sharp corner is first cut system part, plate is cut off in now patrix waste knife cutting edge and the work of counterdie edge iron piece cutting edge, but do not contact with counterdie waste knife, final patrix waste knife punctures after plate descending, while contact, product is cut off with counterdie waste knife.Plate is punctured by patrix waste knife and occurs easily to produce iron filings in the process of fracture.The method that past solves is to take without twice of step waste knife or repeatedly deburring technique, merges surely because technique content constraints differs with other operation contents, often will increase operation, has also increased manufacturing cost.
Summary of the invention
The purpose of this utility model is that proposition is a kind of simple in structure, can avoid again producing in punching course the covering Trimming Die of burr and iron filings, the needs of producing to adapt to Hyundai Motor.
Covering Trimming Die of the present utility model comprises that patrix is installed fixes edge iron piece, the upper model fixing seat of patrix quick-changing type edge iron piece and patrix deburring waste knife, and the die shoe of the fixing edge iron piece of counterdie waste knife and counterdie is installed, key is that described upper model fixing seat inside is provided with the accommodating cavity that Open Side Down, elastomeric element and movable pad are installed in described accommodating cavity, described elastomeric element is between accommodating cavity end face and movable pad, described movable pad is fixed with the movable edge iron piece of patrix, the movable edge iron piece of described patrix is just to counterdie waste knife, when elastomeric element is not during in compressive state, the movable edge iron piece of described patrix, the fixing edge iron piece of patrix, patrix quick-changing type edge iron piece are concordant with the cutting edge of patrix deburring waste knife.
When work; press slide drives the fixing edge iron piece of patrix, patrix quick-changing type edge iron piece and patrix deburring waste knife and the downward movement of the movable edge iron piece of patrix; while starting deburring; because elastomeric element is not in compressive state; therefore the movable edge iron piece of patrix, patrix are fixed edge iron piece, patrix quick-changing type edge iron piece is concordant with the cutting edge of patrix deburring waste knife, and the each trimming edge of patrix coordinates plate is cut off to peripheral plate with the fixing edge iron piece of counterdie.After blank press slide continue descending, the movable edge iron piece of counterdie waste knife contact patrix, and hinder patrix movable blade piece and continue descendingly, and then the movable edge iron piece of patrix exerts pressure to elastomeric element by movable pad, makes elastomeric element compressed.Along with press slide continuation is descending, patrix deburring waste knife coordinates cut-out waste material with counterdie waste knife.Waste material is up with press slide after cutting off, and the movable edge iron piece of patrix resets under the effect of elastomeric element.
Further, controlled for ensureing the movement locus of the movable edge iron piece of movable pad and patrix, and then improve deburring precision, described movable pad and elastomeric element are provided with the guide frame of working in coordination.
Specifically, guide frame has following two kinds:
1, described guide frame is the cylindrical recess that is arranged at movable pad top, and described elastomeric element is cylindrical, and the bottom of elastomeric element is embedded in described cylindrical recess.The sidewall of cylindrical recess can carry out spacing guiding to tubular elastomeric element.Above-mentioned elastomeric element can be cylindrical polyurethane rubber piece.
2, described guide frame is the outstanding cylinder that is arranged at movable pad top, and described elastomeric element is spring, and described cylinder stretches in spring, and cylinder can carry out spacing guiding to spring.
The movable edge iron piece of patrix in the utility model is concordant with all the other each edge iron pieces of patrix; synchronously blank; avoid the generation of burr and iron filings in punching press deburring process, there is the features such as simple in structure, result of use is good, be applicable to the big-and-middle-sized outer covering piece automated production of automobile.
