In order to make those skilled in the art better understand the technical solutions in the application, below to the embodiment of the present application
In technical solution be clearly and completely described, it is clear that described embodiments are only a part of embodiments of the present application,
Instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making creative labor
Every other embodiment obtained under the premise of dynamic, shall fall within the protection scope of the present application.
Further detailed description has been done to the technical solution of the utility model with reference to the accompanying drawing:
As shown in Figs 1-4, a kind of accurate processing unit (plant) in oblique impact hole, including upper mold tiltedly carve 1, punch retainer 2, binder block 3,
Stripper 4, piercing punch component 5, cavity plate component 6, the positioning shaping of positioning shaping terrace die 7, two of die block 9, two are recessed
Mould 10 and several distance screws 11, the upper mold are tiltedly carved 1 and are fixed on upper die holder, and the piercing punch component 5 is fixedly mounted on
On punch retainer 2, several distance screws 11 are locked on stripper 4 by punch retainer 2, and the stripper 4 is logical
It crosses stripper bolt to be fixed on upper die holder, one end of described two positioning shaping terrace dies 7 is respectively and fixedly installed to punch retainer 2
Two sides, and 3 two sides of binder block are located at, the cavity plate component 6 and two positioning correcting dies 10 are fixed on die block 9
On, and two positioning correcting dies 10 are located at 6 two sides of cavity plate component, the other end of described two positioning shaping terrace dies 7 is worn
The convex closure type chamber for crossing stripper 4 and front and back work step cooperates, and carries out shaping positioning, and the upper mold is tiltedly carved 1 and cooperated with punch retainer 2
The die hole cooperating of work, the end of the binder block 3 and cavity plate component 6, described two positioning shaping terrace dies 7 respectively with
Two positioning 10 cooperatings of correcting die.
Preferably, the binder block 3 is T-type structure, including binder transverse slat 3-1 and binder riser 3-2, the binder transverse slat
3-1 and binder riser 3-2 connection in T shape, the end of the binder transverse slat 3-1 and punch retainer 2 are connected, and the binder is perpendicular
The die hole cooperating of plate 3-2 and cavity plate component 6.
Preferably, the binder block 3 and punch retainer 2 are inclined on stripper 4, and tilt angle and cavity plate group
The die hole tilt angle of part 6 is identical.
The course of work of the utility model is as follows:
As shown in Figure 1, before the hole on punching press inclined-plane, first using four one-step forming punch-dies by the convex closure type chamber of workpiece 8 at
In place, this is the prerequisite of the punching on inclined-plane to type, and the shape of final step moulding convex-concave die will determine with when oblique impact hole
Position shaping terrace die matches, i.e. the outer diameter of positioning shaping terrace die is identical with the forming convax mould outer diameter of final step.Convex closure type
The molding of chamber belongs to conventional technical means, so specific forming step does not add detailed description, Fig. 1 is the molding of convex closure type chamber final step
Schematic diagram.
As in Figure 2-4, piercing punch component 5, binder block 3, punch retainer 2 are each attached on stripper, cavity plate group
Part 6 and positioning correcting die 10 are fixed on die block 9.Punching machine power transmission is tiltedly carved on 1 to upper mold when punching press, and upper mold tiltedly carves 1
By being transferred force on piercing punch component 5 with the cooperation of punch retainer 2, to be rushed on the good convex closure type chamber of preforming
Press the precision holes on inclined-plane.At oblique impact hole, the convex closure type for entering first forming by binder block 3 is intracavitary to make coarse positioning and binder work
With, when piercing punch component 5 retract when make discharging effect.While in oblique impact hole, binder block 3 enters the convex closure of forming, punching
The positioning shaping terrace die 7 of front and back work step is also into the intracavitary position positioning as product in a mold of the convex closure type of forming, together
When shaping convex closure bottom surface flatness.The outer diameter for positioning shaping terrace die 7 is identical with the forming convax mould outer diameter of final step, and
