Description
Technical field
The utility model relates to a kind of stamping dies, and in particular to a kind of automobile engine stainless steel thickness flange fine blanking die
Tool.
Background technique
Currently, engine stainless steel thickness flange has 1 macropore and 3 apertures, macropore has a small stair, aperture
Single side has press polish, using the punching press twice of existing process requirement, investigates with regard to working hour, personnel and apparatus factor etc., there are take
When the deficiency taken a lot of work.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiencies in the prior art, provide an a kind of mold
Punching press is completed, location dimension composite precision die tool with high accuracy between hole.
Technical solution: in order to solve the above-mentioned technical problem, composite precision die tool described in the utility model, under it includes
Mould is equipped with lower push rod hole in the lower die, and pressing plate is equipped with above the lower die, and indentation formed punch is equipped on the pressing plate
Hole, macropore bore of the punch and aperture bore of the punch, the pressing plate upper end are connected with upper ejector pin, match and are equipped in the indentation bore of the punch
Formed punch is pressed, matching is equipped with macropore formed punch in the macropore bore of the punch, and matching is equipped with aperture and rushes in the aperture bore of the punch
Head, the front end of the indentation formed punch are circular cone title, and the front end of the macropore formed punch is socket cap, and the diameter of the socket cap is small
In the rear end diameter of macropore formed punch, the matching setting lower push rod in the lower push rod hole.
Workpiece is placed between the lower die and pressing plate.
The workpiece walks to expect that direction is from indentation formed punch side to macropore formed punch side.
The number of the lower push rod is identical as indentation formed punch, macropore formed punch and the total number of aperture formed punch three.
The utility model has the advantages that the utility model is compared with prior art, remarkable advantage is: the setting of the utility model overall structure
Rationally, pit is formed using circular cone title from top to bottom, space is provided for the material flowing of stepped hole, using macropore formed punch and small
Hole formed punch, anti-head punch can form bright and high quality macropore, realize that a mold completes punching press, engine stainless steel thickness
Flange is formed using a mould punching, and location dimension quality is high between having the advantages that hole, and product qualification rate is increased to 99.5%,
Work efficiency improves 50% or more.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, composite precision die tool described in the utility model, it includes lower die 1, is equipped in the lower die 1
Lower push rod hole is equipped with pressing plate 2 above the lower die 1, workpiece 10 is placed between the lower die 1 and pressing plate 2, in the pressing plate
2 are equipped with indentation bore of the punch, macropore bore of the punch and aperture bore of the punch, and 2 upper end of pressing plate is connected with upper ejector pin 3, in the pressure
Matching is equipped with indentation formed punch 4 in recessed bore of the punch, and matching is equipped with macropore formed punch 5 in the macropore bore of the punch, rushes in the aperture
Matching is equipped with aperture formed punch 6 in head bore, the workpiece 10 walk to expect direction be from indentation 4 side of formed punch to 5 side of macropore formed punch,
The front end of the indentation formed punch 4 is circular cone title 7, and the front end of the macropore formed punch 5 is socket cap 8, the diameter of the socket cap 8
Less than the rear end diameter of macropore formed punch 5, matching setting lower push rod 9, the number and pressure of the lower push rod 9 in the lower push rod hole
Recessed formed punch 4, macropore formed punch 5 are identical with the total number of 6 three of aperture formed punch.The setting of the utility model overall structure rationally, uses
Circular cone title forms pit from top to bottom, provides space for the material flowing of stepped hole, using macropore formed punch and aperture formed punch, instead
Head punch can form bright and high quality macropore, realize that a mold completes punching press, engine is used with stainless steel thickness flange
One mould punching forms, and location dimension quality is high between having the advantages that hole, and product qualification rate is increased to 99.5%, and work efficiency improves
50% or more.
The utility model provides a kind of thinking and method, and there are many method and the approach for implementing the technical solution, with
It is only preferred embodiments of the present invention described in upper, it is noted that for those skilled in the art,
Without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications should also regard
For the protection scope of the utility model, all undefined components in this embodiment can be implemented in the prior art.
