Description
Technical field
The present invention relates to the punching die of symmetrical holes is rushed in a kind of automobile rocker upper u-shaped portion.
Background technology
As shown in figure 1, two symmetrical through holes of punching press in automobile rocker upper u-shaped portion, are required, and two holes have concentricity to want
Ask, general tolerance requires to ensure in the range of 0.2mm.
It is as the thickness of automobile rocker is generally higher than 1.5mm, relatively thick, required punching press great efforts, and U-shaped portion cross section
Width is generally less than 20mm, if adopting the direct punching press of single drift, punching press dynamics not enough, and is easily damaged die point.
In order to ensure the intensity the problem in view of discharge space of die point, typically using first one side punching, second
Operation completes another side punching.Two punching concentricitys of this processing mode need the precision and good positioning of pattern tool to come true
Protect.Because a point two-step punching press is completed, two mold frocks are needed.And due to mould processing cumulative error, plate position error, plate
The stability of part punching press is not good, and tolerance cannot be controlled in 0.2mm tolerances very well.

The invention has the beneficial effects as follows：This stamping mold is provided with the blanking channel being connected with forming hole in core,
Core both sides adopt punch simultaneously, even if U-shaped part biside plate discharge position is very close to can also provide sufficiently large punching press
Power, and very high concentricity requirement can be met；As axially extending bore is provided with drift, waste material top in the axially extending bore of drift, is provided with
Material bar, is provided with nitrogen spring between waste material ejector beam and drift mounting seat, when punching, slug band is led to by drift to blanking
In road, when drift is return, waste material is released by waste material ejector beam and is fallen within blanking channel, waste material is smoothly discharged, it is to avoid
Waste material is stuck in the forming hole of core, so as to avoid damaging core.
And this mould meets the punching press simultaneously of two side punchings, offsets side force, it is ensured that mould stress balance；Simultaneously punching press can be with
Stamping procedure is reduced, efficiency is improved；Punching press with one heart guarantees product concentricity, it is ensured that stability.Making mold is also reduced in addition
Cost.
As drift mounting seat is provided with binder block, binder block is connected with drift mounting seat by nitrogen spring, binder
Installation through-hole is provided with the middle part of block, the drift passes through installation through-hole so that material is first compressed by binder block before punch material,
Avoid material that big deformation is produced in punching press so that punching quality is more preferable.
As drift mounting seat is provided with two lead columns parallel to drift, binder block is set in lead column so that
The motion of binder block is more steady.
As die shoe is provided with perpendicular to the section of drift axial direction guide pad triangular in shape, rushing on upper bolster
Head mounting seat is provided with gathering sill of the section in del being engaged, and guide pad causes upper bolster to transport with the cooperation of gathering sill
It is dynamic more accurate, so as to wedge accurately promotes drift peace swivel base.
Material jacking seat is movably equipped with by core on die shoe, jacking bullet between material jacking seat and die shoe, is provided with
Material is deviate from from core after being easy to processing by spring.
Prevent upper bolster from pushing excessive limited block as die shoe is provided with, can prevent upper bolster from pushing excessive damaging by pressure
Surface of material.
