And the bottom of each punching press cavity is installed with resetting spring, the top of each resetting spring is connected with punching template.
In a preferred embodiment of the present invention, the left-hand end of the upper surface of the bed die is equipped with step-feeding cylinder.
In a preferred embodiment of the present invention, it is installed with push rod on the cylinder rod of the step-feeding cylinder.
In a preferred embodiment of the present invention, the grading spacing distance of the step-feeding cylinder and adjacent two punching presses cavity
Spacing distance it is identical.
In a preferred embodiment of the present invention, each punching template is all in the same horizontal plane when standing.
In a preferred embodiment of the present invention, it is to be detachably connected between the punching template and the resetting spring.
The beneficial effects of the invention are as follows：A kind of step-feeding diel of the present invention, it is multiple by using being arranged on bed die
The punching press cavity that depth is sequentially increased, and have the punch that multiple length are sequentially increased in the lower section installation settings of stamping die, pass through
The step-feeding punching press to product is completed in the cooperation of each punch and each punching press cavity；In addition, being mounted in each punching press cavity multiple
Position spring, by product automatic spring, can be convenient for subsequent punching press after each punching press cavity punching press, final to improve step-feeding punching
The precision of pressure, and production efficiency can be accelerated.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention in a preferred embodiment；
The label of each component is as follows in attached drawing：1, stamping die, 2, bed die, 3, step-feeding cylinder, 11, pressed sheet, 12, punch, 21,
Punching press cavity, 22, resetting spring, 23, punching template, 31, push rod.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of step-feeding diel, including：Stamping die 1 and bed die 2, the stamping die 1 are located at the surface of the bed die 2；
The lower section of the stamping die 1 is installed with pressed sheet 11, and the lower section of the pressed sheet 11 is installed with multiple punches
12, the length of each punch 12 is sequentially increased from left to right；
The upper surface of the bed die 2 offers multiple punching press cavities 21, and the depth of each punching press cavity 21 is from left to right successively
Increase, and the bottom of each punching press cavity 21 is installed with resetting spring 22, the top connection of each resetting spring 22
There is punching template 23.
It further illustrates, the left-hand end of the upper surface of the bed die 2 is equipped with step-feeding cylinder 3, the step-feeding cylinder 3
Cylinder rod on be installed with push rod 31, the product that will be popped up out of punching press cavity 21 push to the position of latter punching press cavity 21
It sets.
It further illustrates, the spacing distance of the grading spacing distance of the step-feeding cylinder 3 and adjacent two punching presses cavity 21
Identical, the cylinder rod of the step-feeding cylinder 3, which can be classified, to be extended, thus by product along each grading punching press cavity 21
Interval gradually pushed.
It further illustrates, each punching template 23 is all in the same horizontal plane when standing, and can be ensured in each punching press
Press depth in cavity 21 is incremented by step by step, is further ensured that the precision of progressive stamping.
Further illustrate, it, being capable of basis to be detachably connected between the punching template 23 and the resetting spring 22
Different punching press shapes replaces the punching template 23 of different structure, improves adaptive type.
It is different from the prior art, present invention is disclosed a kind of step-feeding diel, specific works step is as follows：
（1）The right side for being positioned over push rod 31 by be punched piece starts step-feeding cylinder 3, punching press cavity is pushed to by be punched piece
21 tops, step-feeding cylinder 3 bounce back；
（2）Start stamping die 1, under the connection of pressed sheet 11, product punching press is entered punching press cavity by 12 downward punching press of punch
