Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As depicted in figs. 1 and 2, a kind of punch stretching mould, including upper mould and the lower mould that is matched with the upper mould, it is described on
The upper plate of mould is provided with holding pad 1, and the holding pad 1 is located at the dynamic position concentrated of stamping plate stream in the upper plate
On, the holding pad 1 is provided with the push rod 2 placed vertically, and the top of the push rod 2 is fixed on the holding pad 1, the top
The edge of the hanging and close lower mould in the bottom of bar 2, the edge of the lower mould are provided with blank holder 3, and the lower mould is provided with
For withstanding the pendulum opportunity structure of the push rod 2, and the pendulum opportunity structure closes close to the blank holder 3 in the upper die and lower die
During mould, the pendulum opportunity structure withstands the push rod 2.
In this specific embodiment：The push rod 2 is provided with two, and two push rods 2 are symmetrically fixed on the binder
On plate 1.The pendulum opportunity structure is provided with two, and two pendulum opportunity structures are symmetrically installed on the lower mould, and positioned at described
Two of blank holder 3.
The holding pad 1 is particularly located at the middle part in the upper plate, and the punch-pin among face stamping parts plate.
The upper mould is provided with the first nitrogen spring for being used for that pressure source to be provided to the holding pad 1, is set on the lower mould
There is the second nitrogen spring for providing pressure source to the blank holder 3.
The pendulum opportunity structure includes pendulum contract 4, the first pushing unit and the second pushing unit, and one end of the pendulum contract 4 can be put
Dynamic is fixed on the lower mould, and the other end of the pendulum contract 4 be located at the lower section of the push rod 2, first pushing unit with
Respectively positioned at the inner side and outer side of the pendulum contract 4, first pushing unit is used to promote institute in die sinking second pushing unit
State pendulum contract 4 to swing to the direction away from the blank holder 3, second pushing unit is used to promote the pendulum contract 4 in matched moulds
Swung to close to the direction of the blank holder 3.First pushing unit includes the 3rd nitrogen spring 5 and push rod 6, and the described 3rd
Nitrogen spring 5 is embedded in the lower mould, and one end of the push rod 6 is connected on the 3rd nitrogen spring 5, the push rod 6
The other end close to the inner side of the pendulum contract 4, the push rod 6 promotes institute under the driving of the 3rd nitrogen spring 5 during die sinking
State pendulum contract 4 to swing to the direction away from the blank holder 3, make the bottom of the pendulum other end of contract 4 away from the push rod 2.Institute
Stating the second pushing unit includes sliding block 7, the nitrogen spring 9 of sliding bearing 8 and the 4th, and the sliding block 7 is pacified by the sliding bearing 8
In the lower mould, and one end of the sliding block 7 is additionally provided with for driving on the outside of the pendulum contract 4, the lower mould
The 4th nitrogen spring 9 that the sliding bearing 8 slides, the sliding bearing 8 is in the 4th nitrogen spring 9 during matched moulds
Drive lower band movable slider 7 to be slided to close to the direction of the pendulum contract 4, and make the another of the pendulum contract 4 under the promotion of the sliding block 7
Withstand the bottom of the push rod 2 in one end.
Operation principle of the present utility model is：When upper mould is up walked with press slide, holding pad 1 makes with blank holder 3
With nitrogen spring, blank holder 3 up moves in the presence of the second nitrogen spring, effect of the holding pad 1 in the first nitrogen spring
It can move down, but now the pendulum contract 4 on blank holder 3 can push push rod 2 and allow holding pad 1 not move down, when the stroke of blank holder 3
Contract 4 is put while covering to swing out due to the promotion of the 3rd nitrogen spring 5, pendulum contract 4 is departed from push rod 2, and holding pad 1 is again down
Mobile, such stamping parts would not be weighed wounded, and so as to play a time-lag action, and upper mould is due to realizing the shaping under binder state,
So as to solve the problems, such as the corrugation of stamping parts.
It is specific as shown in figure 1, status architecture signal when Fig. 1 is a kind of punch stretching mould matched moulds of the utility model
Figure, during matched moulds, upper bolster is moved downwardly to bottom dead centre, and now holding pad 1 pushes down plate, makes the surface more smooth of plate, is not easy
Corrugation.
Fig. 2 is the status architecture schematic diagram that a kind of punch stretching mould die sinking of the utility model is, under die opening state, is pushed away
Bar 6 is free state with pendulum contract 4, and push push rod 6 under the active force of the 3rd nitrogen spring 5 swings out pendulum contract 4, puts contract 4
Do not contacted with push rod 2 when upper bolster moves downward, now, the holding pad 1 of upper mould first pushes down plate and starts to be molded again, Ke Yiqi
To the effect of binder；With the closure of mould, while plate shaping is stamping parts, pendulum contract 4 is in sliding bearing 8, sliding block 7 and the
Toward backswing (but not contacted with push rod 6) under the collective effect of four nitrogen springs 9, when mould closes completely, in the 4th nitrogen bullet
Push sliding block 7 in the presence of the power of spring 9 makes pendulum contract 4 return to Fig. 1 states, pendulum contract 4 is withstood push rod 2.
A kind of punch stretching mould of the utility model is different from the structure that the upper plate of traditional upper mould is stiff, this reality
With new holding pad individually designed on upper plate, it is pressed on the dynamic position concentrated of stamping plate stream, lower mould designs blank holder；
When mould has pressed after stamping parts motion upwards, because upper molding flitch and lower molding flange occur while push up stamping parts by punching press
The phenomenon that part damages by pressure, in order to prevent damaging stamping parts by pressure, designed by blank holder and put opportunity structure, holding pad and lower blank holder in control
Priority motion it is smooth, ensure lower blank holder jack up completely come after upper holding pad start liftout again, do not weigh stamping parts wounded；This practicality
It is new while ensureing mould normally production do not weigh stamping parts wounded, due to being set at the dynamic position excessively concentrated of stamping plate stream
Holding pad on meter, makes stamping parts be molded in the state of compression, ensures the uniformity of material flowing, solves stamping parts well
The problem of corrugation.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
