Description
Technical field
The utility model relates to stamping die technology, in particular to a kind of positive stamping die.
Background technique
When carrying out the production of automobile gearbox spring(-supported) mount using stamping die, two molds is needed to carry out first square impact to material strip
Rear side punches the processing of Cheng Zhengkong and side opening, but existing structure side blow edge of a knife intensity is weak, and when production is easy to crumble, and uses
When need the production of two sets punching machines, increase cost of labor and equipment cost.
Utility model content
In view of the deficienciess of the prior art, the main purpose of the utility model is to provide one kind to go out simultaneously just
The positive stamping die in hole and gaging hole.
To achieve the above object, the utility model provides following technical solution: a kind of positive stamping die, including upper mold is under
Mould, the upper mold include positive stamping punch, and the lower die includes lower template, and material strip to be punched is provided in the lower template, described
Material strip to be punched includes " factory " oxbow portion, and the bending section includes positioned at the square impact portion of bottom and on segmental arc
It squeezes and cuts portion, the lower template includes the tangent lower die edge of a knife below square impact portion and cuts mould positioned at cut below portion crowded is squeezed
The edge of a knife, the crowded left side wall for cutting the mould edge of a knife are aligned in the middle part of portion with crowded cut, and the positive stamping punch includes and square impact lower die cutter
The the first punching section and the second punching section being correspondingly arranged with the crowded portion of cutting, the second punching section that mouth is correspondingly arranged are broken through downwards
It squeezes behind portion of cutting and is bonded setting with the crowded left side wall for cutting the mould edge of a knife.
Preferably, the lower end of the first punching section is provided with the first curved transition sections.
Preferably, the second punching section includes cutting the second curved transition sections that the shape in portion is correspondingly arranged with crowded.
The utility model has the following advantages compared with the prior art, and the course of work is, upper mold drive positive stamping punch to
Lower movement, the first punching section contact square impact portion first, continue downwards, and positive hole is gone out in square impact portion, and the first punching section, which enters, just to be cut
In the mould edge of a knife, then the second punching section is contacted with the crowded portion of cutting, and upper mold drives positive stamping punch to continue downwards, and the second punching section pressure arrives
It squeezes to cut and continue in portion downwards, the second punching section cooperation, which is squeezed, cuts the mould edge of a knife and cut and cut out gaging hole in portion squeezing, and squeezes and cuts the mould edge of a knife
Left side wall is cut and is aligned in the middle part of portion with squeezing, the second punching section is broken through downwards squeeze portion of cutting after be bonded with the crowded left side wall for cutting the mould edge of a knife
Setting.Processing while compared with the existing technology positive hole and gaging hole can be realized by a set of positive stamping die in this programme, section
It has saved cost and has improved efficiency.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of positive stamping die, including upper mold 1 and lower die, the upper mold 1 includes positive stamping punch 2, under described
Mould 3 includes lower template 4, and material strip to be punched is provided in the lower template 4, and the material strip to be punched includes " factory " oxbow portion
5, the bending section 5 includes that portion 7 is cut positioned at the square impact portion 6 of bottom and crowded on segmental arc, and the lower template 4 includes position
The mould edge of a knife 9 is cut in the tangent lower die edge of a knife 8 of 6 lower section of square impact portion and positioned at the crowded of 7 lower section of portion of cutting is squeezed, described squeeze cuts lower die cutter
The left side wall of mouth 9 is aligned with the middle part for cutting portion 7 is squeezed, and the positive stamping punch 2 includes first be correspondingly arranged with the square impact lower die edge of a knife
Punching section 10 and cut the second punching section 11 that portion 7 is correspondingly arranged with squeezing, the second punching section 11 is broken through downwards squeeze and cut portion 7 after
Setting is bonded with the left side wall for cutting the mould edge of a knife 9 is squeezed.
A kind of positive stamping die of this programme, the course of work are that upper mold 1 drives positive stamping punch 2 to move downward, the first punching
Section 10 contacts square impact portion 6 first, continues downwards, and positive hole is gone out in square impact portion 6, and the first punching section 10 enters in the tangent lower die edge of a knife 8,
Then the second punching section 11 is cut portion 7 and is contacted with squeezing, and upper mold 1 drives positive stamping punch 2 to continue downwards, and the second punching pressure of section 11 arrives crowded
It cuts and continues in portion 7 downwards, the second punching cooperation of section 11, which is squeezed, cuts the mould edge of a knife 9 and cut and cut out gaging hole in portion 7 squeezing, and squeezes and cuts the mould edge of a knife
