Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present invention further detailed
Explanation, it is more complete, accurate and deep to help those skilled in the art to have the inventive concept of the utility model, technical solution
The understanding entered.
As shown in Figure 1-Figure 3, the utility model provides a kind of composite die of punching press bracket of back axle, including upper die holder 1,
Lower die holder 4, the cavity plate 6 being mounted in the fixed plate 5, is fixed on the upper die holder 1 at the fixed plate 5 being fixed on lower die holder 4
On punch case 2, the punch-pin 3 being fixed below the punch case 2, the guide sleeve 11 that is mounted on the upper die holder 1 and be mounted on
Guide post 10 on the lower die holder 4, the guide sleeve 11 are slidably matched with the guide post 10.Limit is also equipped on the lower die holder 4
Position column 16, the height of the limited post 16 by technique require in the press-bending depth of workpiece determines, equal to the press-bending depth symbol of workpiece
The spacing of upper die holder 1 and the lower die holder 4 after molding in the case of technique requires is closed, such limited post 16 both can guarantee upper die holder
1 falling head guarantees stamping forming consistency, and can prevent lower die holder to realize the requirement for bending depth to workpiece
Excessive descent causes burn failure.
It is positioned between the punch case 2 and the upper die holder 1 by punch-pin positioning pin 18, and solid by multiple upper bolts 17
It is fixed.It is equipped with the step-like mounting hole cooperated with 3 shaped upper part of punch-pin in the punch case 2, with 3 stake-fastening of punch-pin.Institute
It states and is positioned by cavity plate positioning pin 20 between 4 three of cavity plate 6, fixed block and the lower die holder, and is fixed by lower bolt 19, it is described
Cavity plate positioning pin 20 passes through the fixed block.
Composite die further includes kicker 7 and mandril 8.The cavity plate 6 and 5 center of the fixed plate are equipped with and the head part
The inner mold chamber 9 that block 7 is slidably matched, the inner mold chamber 9 merge and the side bending part of the bracket of back axle with the punch-pin 3 matching
Divide shape matching, to realize the bending and shaping of blank.
7 top of kicker and 3 bottom of punch-pin are the inclined-plane being mutually matched, the inclined-plane and the bracket of back axle
Bottom shape matches, and 7 bottom of kicker is equipped with several mandrils 8, and the mandril 8 is connected to the lower die holder 4
On the taking blame for others of lower section, under initial state, blank is mounted on the inclined-plane of the kicker 7, and the blank passes through two blanks
Positioning pin 12 positions and is higher than 6 top of cavity plate.It can guarantee the tilt angle energy of blank bottom surface during punch forming in this way
Guaranteed by inclined-plane.If the position of blank can be accurately positioned in this way it is ensured that the ground of bracket of back axle after being formed,
Side dogleg section all meets production requirement.
Two blank positioning pins corresponding with location hole 21 on bracket of back axle are installed on the inclined-plane at 7 top of kicker
12,3 bottom of punch-pin has the dowel hole 13 for accommodating 12 extension of blank positioning pin.The blank positioning pin 12
The part for being pressed into kicker 7 is cylinder, and the cross section of extension is dolioform.Thus it is able to achieve to blank on inclined-plane
It is accurately positioned, guarantees the consistency and qualification rate of formed product, and can be reduced contact portion, facilitate the placement of blank.
The cavity plate intrados matched with the flange shape of the bracket of back axle is equipped at the top of the inner mold chamber 9 of the cavity plate 6
14, there is on the outside of the punch-pin 3 the punch-pin extrados 15 matched with the cavity plate intrados 14.When the two cambered surface parts are pressed
The flange to the top of bracket of back axle can be completed after conjunction.
The inside that the inner mold chamber 9 is located at the higher side of the kicker 7 has and bracket of back axle side bending part
The protrusion that the outer concave part divided matches, the shorter side outside of convex block length are recessed with matching with the protrusion
Concave portion.This is the apparent sunk structure of side dogleg section in order to cooperate bracket of back axle ipsilateral.The kicker 7 and the top
Bar 8 is connected through a screw thread fixation, then can guarantee the driving effect to kicker 7.
The course of work of this mold are as follows: the blank for being equipped with location hole 21 is mounted on the inclined-plane of kicker 7 first, blank is fixed
Positioning is realized in position pin 12 and the cooperation of location hole 21, and blank lower end is higher than 6 top of cavity plate at this time.Then it is pressed downward by stamping device
Close, the inclined-plane of 3 bottom of punch-pin contact pressing with blank first, kicker 7 take blame for others act under keep enough pressing forces, and
Punch-pin 3 moves down under acting on.Since the inclination angle of bracket of back axle bottom surface relative level is 15 °, blank will not in punching course
It arches upward upwards.As punch-pin 3 is moved down with kicker 7 along inner mold chamber 9, the part of bottom surface periphery is in the case where punch-pin 3 and inner mold chamber 9 act on
Bending and molding.When lower die holder 4 is depressed into close to limited post 16, cavity plate intrados 14 and punch-pin extrados 15 start cooperation to this
When blank upper end carry out flange.It is withstood when lower die holder 4 is limited column 16, punch-pin 3 and cavity plate 6 are completed to press, and realize to rear
Bracing strut it is one time punching molded, successively complete the process of bending, shaping and flange.Then upper die holder 1 rises, kicker 7
Also rise with the effect taken blame for others and taken blame for others, start to demould.When workpiece is detached from inner mold chamber 9, punch-pin 3 completes demoulding after rising reset.
Need bending flange to form for similar, and the mounting hole direction used for positioning i.e. bottom surface not vertical with workpiece bottom of bottom surface with
The angled workpiece of horizontal plane, it is possible to use formed with this mold similar structures.
This composite die by kicker 7 realize processing before to the blank i.e. positioning of thick steel plate, be able to maintain thick steel plate
With the consistent state of tilt angle needed for bracket of back axle bottom surface, the one time punching molded of bracket of back axle is realized, shortens production
Period, the consistency and quality qualification rate for the product that reduces that increased production cost.
