Description
Technical field
The utility model relates to punching die technical field, particularly a kind of liftout type punching die.
Background technology
Mould, as one of high efficiency tool of production, is in industrial production, to use very extensive and important production equipment.Adopt mould article of manufacture and part, there is production efficiency high, can realize the large batch of production of high speed, save material, realize without machining; Constant product quality, has good interchangeability, simple to operate, to operating personnel, does not have very high technology will wait advantage.
Punching die is modal a kind of in mould, and along with the development of technology, people are more and more higher to the quality requirement of product, but that existing punching die exists positioning precision is conventionally not high, and die life is short, ineffective problem.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides that a kind of positioning precision is high, mould maintenance cost is low and the liftout type punching die of high punching efficiency.
The purpose of this utility model is achieved through the following technical solutions: a kind of liftout type punching die, it comprises upper bolster, die shoe, guide pillar, liftout type punch, die, movable stripper and location-plate, the middle part, upper surface of upper bolster is fixed with die shank, die shank is connected with the transmission of external impetus equipment, upper bolster and die shoe arrange in opposite directions, many guide pillars are vertically fixed on die shoe, are fixed with guide pin bushing on upper bolster, and guide pillar and guide pin bushing are slidably matched; The middle part, upper surface of die shoe is fixed with die, and is located by alignment pin, and the upper surface of die is fixed with location-plate; The middle part, lower surface of upper bolster is fixed with backing plate and punch retainer from top to bottom successively, on punch retainer, be installed with liftout type punch, liftout type punch is corresponding with die, the below of punch retainer is also provided with movable stripper, and movable stripper is connected by stripper bolt with upper bolster.
Described upper bolster, backing plate punch retainer are fixedly connected with by many hexagon socket head cap screws.
The screw portion of described stripper bolt is also set with spring, and one end of spring is fixed on the lower surface of backing plate, and the other end of spring is fixed on the upper surface of movable stripper.
The lower end of described liftout type punch is also provided with liftout type assembly.
Described spring is rectangular coil spring.
The utlity model has following advantage:
1, die positions by alignment pin, and in die upper surface, location-plate is set, and workpiece is placed in the middle of location-plate, punch is located when punching more accurate.
2, between guide pillar and upper bolster, guide pin bushing is set, and guide pin bushing is fixed on upper bolster, guide pin bushing is relative with upper bolster static, and upper bolster is when moving up and down, and upper bolster can not be worn, and increases die life.
3, rectangular coil spring is set between backing plate and stripper, when upper bolster moves down, rectangular coil spring-compressed, increase pressure-plate-force, punching is rapider, while moving to certain altitude on upper bolster, rectangular coil spring extends, stripper is driven together and moved, work more steady, improve punching efficiency.
Accompanying drawing explanation
