Description
Technical field
The utility model relates to a kind of blanking die, is specifically related to the accurate hot piercing mould in a kind of gear former hole.
Background technology
In traditional gear forgings with former hole is produced, the Blade dimensions of piercing punch is less than the Blade dimensions of punching concave die, and in punch process, piercing punch cutting edge can pass punching concave die cutting edge, by stamping for the hole on gear former.This hole punching technological process can produce longitudinal burr around hole.These longitudinal burrs have to pass through polishing and clean out.Time-consuming, power consumption, polishing environment is also poor, has a strong impact on the healthy of workman.
Therefore, need to improve punching technology in prior art, to eliminate the impact of punching burr, improve punching quality, improve working environment.
Summary of the invention
The purpose of this utility model is for above-mentioned technical problem, provides a kind of gear former hole accurate hot piercing mould, improves punching quality, improve working environment.
In order to solve the problems of the technologies described above, technical solutions of the utility model are: the accurate hot piercing mould in a kind of gear former hole, comprise upper bolster, essence rushes punch, rush school patrix, the end face of upper bolster is connected with the slide block on machine tool, essence is rushed punch and is fixed by screws on upper bolster bottom surface, rush the stop screw being provided with in the patrix of school and being connected with upper bolster, rush school patrix and rush punch vertical direction by stop screw along essence and move up and down, rush school patrix and be connected with the nitrogen spring in upper bolster; Also comprise die shoe, rush school counterdie, rush school counterdie and be fixed by screws on die shoe end face; Rush school patrix and rush school counterdie and be combined and form complete gear former die cavity, the stamping-out end that essence rushes punch is corresponding with the pre-punched hole place on gear face; It is characterized in that: rush in the counterdie cutting edge of school and be provided with backing-out punch, backing-out punch is connected with the nitrogen spring in die shoe by supporting plate, ejecting of backing-out punch holds the stamping-out end rushing punch with essence corresponding, ejecting of backing-out punch holds diameter identical with the stamping-out end diameter that essence rushes punch, and essence rushes the degree of depth that the stroke distances of punch stamping-out end in gear former is slightly less than pre-punched hole; In punch process, it is servo-actuated together that essence rushes both punch and backing-out punch, and essence is rushed after punch punching terminates, and be positioned at the punching recess rushing school counterdie cutting edge and be not separated with hole, punching recess is ejected by backing-out punch and rushes in the counterdie cutting edge of school, realizes punching place impulse-free robustness.
Further limit technique scheme, described essence rushes the degree of depth 0.5 ~ 1.0mm that the stroke distances of punch stamping-out end in gear former is slightly less than pre-punched hole; Such punching precision that can make is higher.
Beneficial effect: 1. the utility model punching can be sheared that bright and clean band reaches gear disc thickness more than 80%, punching precision is higher; 2. the gear disc that the utility model is produced do not have punching burr, overcome the impact of the punching burr that traditional punching technology is formed, and eliminate polishing operation, the once processing of complete hole pairs, thus evade the impact of air exercise mill workers ' health in polishing punching burr process.

Detailed description of the invention
As shown in Figure 1, the accurate hot piercing mould in a kind of gear former hole, comprise upper bolster 1, essence rushes punch 2, rush school patrix 3, the end face of upper bolster 1 is connected with the slide block on machine tool, essence is rushed punch 2 and is fixed by screws on upper bolster 1 bottom surface, rushes in school patrix 3 stop screw 4 being provided with and being connected with upper bolster 1, rushes school patrix 3 and rushes punch 2 vertical direction by stop screw along essence and move up and down, rush school patrix 3 to be connected with the nitrogen spring 5 in upper bolster 1, rush school patrix 3 by nitrogen spring 5 return; Also comprise die shoe 6, rush school counterdie 7, rush school counterdie 7 to be fixed by screws on die shoe 6 end face, rush in school counterdie 7 cutting edge and be provided with backing-out punch 8, backing-out punch 8 is shaft-like, backing-out punch 8 is connected with the nitrogen spring 5 in die shoe 6 by supporting plate 9, and backing-out punch 8 is by nitrogen spring 5 return; Rush school patrix 3 and rush school counterdie 7 and be combined and form complete gear former die cavity, the stamping-out end that essence rushes punch 2 is corresponding with the pre-punched hole place on gear face, ejecting of backing-out punch 8 holds the stamping-out end rushing punch 2 with essence corresponding, and ejecting of backing-out punch 8 holds diameter identical with the stamping-out end diameter that essence rushes punch 2; Essence rushes the degree of depth 0.5 ~ 1.0mm that the stroke distances of punch 2 stamping-out end in gear former is slightly less than pre-punched hole, namely essence rush punch travel to the most lower in limited time, essence rushes punch stamping-out end face and the distance of rushing between counterdie cutting edge face, school is 0.5 ~ 1.0mm; In punch process, it is servo-actuated together that essence rushes both punch and backing-out punch, and essence is rushed after punch punching terminates, and be positioned at the punching recess rushing school counterdie cutting edge and be not separated with hole, punching recess is ejected by backing-out punch and rushes in the counterdie cutting edge of school, realizes punching place impulse-free robustness.
As shown in Figure 1, described upper bolster and die shoe are equipped with the bend pipe 10 and hose coupling 11 that connect cooling water, pass into cooling water in the course of work, nitrogen spring is cooled.
Utility model works principle: as shown in Figure 2, in gear former punch process, rushed school patrix and upper bolster before this with the slide block down on punch press, and made to rush school patrix and rush school counterdie to contact with gear face; As shown in Figure 3, essence carries out punching after rushing the pre-punched hole on punch stamping-out end in contact gear face, and in punch process, it is servo-actuated together that essence rushes both punch and backing-out punch; When the slide block on punch press arrives lower bound range, punch process terminates, and now essence is rushed punch and do not entered and rush in the counterdie cutting edge of school, and the punching recess swept away is not separated with hole; As shown in Figure 4, when rushing school patrix and upper bolster with slide block return on punch press, the punching recess rushed in the counterdie cutting edge of school, under the effect of nitrogen spring, ejects by backing-out punch, finally the gear former after punching and punching recess is taken out, completes processing.The utility model is actually and has carried out positive and negative twice punching, and hole place can be avoided so well to occur the problem of burr.
The content be not described in detail in this description belongs to the known prior art of professional and technical personnel in the field.
