Description
Technical field
This utility model relates to a kind of device for peeling, specifically forces return structures.
Background technology
During mold work, punch is fixed bar and is slided along angled-lift splits inclined-plane, resistance during spring overcoming workpiece backhaul
Power.The most often occur the excessive punch of resistance cannot backhaul, workpiece is stuck on punch cannot discharging
Problem.
Utility model content
The purpose of this utility model is that providing a kind of forces return structures, and this structure controls convex by hinge
The stroke of mould, solving that punch is stuck on punch retainer cannot the problem of backhaul, it is ensured that workpiece is just
Often discharging, improves work efficiency.
The technical scheme in the invention for solving the technical problem is: force return structures, its knot
Structure includes that punch, punch fix bar, hinge, angled-lift splits, angled-lift splits fixed plate and punch retainer, institute
Stating punch to fix bar with punch and be connected by screw, described punch is fixed bar and is connected through the hinge with angled-lift splits,
Described angled-lift splits is fixed by screw with angled-lift splits fixed plate, and one end of described hinge is provided with to be fixed with punch
The installing hole that bar is fixing, the other end of hinge is provided with pin-and-hole, is provided with roller pin in described pin-and-hole.
Further, described punch retainer is provided with card and puts the hole of guide pin bushing, and it is solid that described guide pin bushing is arranged on punch
The rear portion of fixed pole.
Further, the free end of fixing screw is fixed bar with punch after passing hinge one end installing hole and is connected,
The free end of roller pin is connected with angled-lift splits top after pin-and-hole.
Further, the pin-and-hole of described hinge end section is an elongated hole.
The beneficial effects of the utility model are:
1, this structure is fixed bar punch and is connected through the hinge with angled-lift splits, owing to hinge controls punch
Stroke, thus can solve punch be stuck on punch retainer cannot the problem of backhaul, force punch backhaul to be protected
Demonstrate,prove the normal discharging of workpiece, improve work efficiency.
2, owing to being provided with guide pin bushing on punch retainer, guide pin bushing is arranged on punch and fixes the rear portion of bar and can prevent
Only punch is fixed bar and is directly contacted friction with punch retainer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of hinge in this utility model；
Fig. 3 is free state structural representation of the present utility model；
Fig. 4 is working state schematic representation.
In figure: 1 punch, 2 punch fix bar, 3 screws, 4 hinges, 5 roller pin, 6 installing holes, 7
Angled-lift splits, 8 angled-lift splits fixed plates, 9 punch retainers, 10 guide pin bushings, 11 pin-and-holes.
Detailed description of the invention
With reference to Figure of description, pressure return structures of the present utility model is described in detail below.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, pressure return structures of the present utility model, its structure bag
Include punch 1, bar 2 fixed by punch, hinge 4, angled-lift splits, angled-lift splits fixed plate 8 and punch retainer 9,
Described punch 1 is fixed bar 2 and is connected by screw 3 with punch, and described punch fixes bar 2 and angled-lift splits 7
Being connected by hinge 4, described angled-lift splits 7 is fixed by screw with angled-lift splits fixed plate 8, described hinge
One end be provided with and fix, with punch, the installing hole 6 that bar is fixing, the other end of hinge 4 is provided with pin-and-hole 11, institute
Roller pin 5 it is provided with in stating pin-and-hole.
Described punch retainer 9 is provided with card and puts the hole of guide pin bushing 10, and it is solid that described guide pin bushing 10 is arranged on punch
The rear portion of fixed pole 2, can prevent punch from fixing bar 2 and directly contact with punch retainer 9 and frictionally secure plate,
Guide pin bushing can periodically be replaced, and punch retainer is difficult to change.
The free end of fixing screw is fixed bar 2 with punch after passing hinge 4 one end installing hole and is connected, rotating shaft
The free end of pin 5 is through being connected with angled-lift splits 7 top after pin-and-hole, and hinge 4 pivot pin 5 that rotates swings, and controls
Punch 1 stroke processed.
The pin-and-hole of described hinge 4 end is an elongated hole, the stroke of the length limitation punch of elongated hole, it is ensured that
During free state, punch travel is less than the stroke of punch retainer, it is ensured that all demouldings, prevents workpiece
Blocking cannot discharging.
When mould is opened, punch retainer floats under the action of the spring, and punch and punch fix bar along convex
Mould fixed plate is slided, and hinge is fixed by screws in punch and fixes on bar, and the pivot pin that rotates swings, and works as hinge
When being rocked to another dead point, punch cannot be followed punch retainer and be continued to slide, and punch is fixed less than punch
Plate, workpiece will not be stuck on punch, it is achieved all the demoulding of punch ensure that the discharging of workpiece is smooth and easy.
Pressure return structures of the present utility model controls the stroke of punch by hinge, solves punch and is stuck in
Cannot the problem of backhaul on punch retainer, it is ensured that the normal discharging of workpiece, improve work efficiency.
The above, simply explain through diagrams principles more of the present utility model, and this specification is not intended to
This utility model is confined in shown described concrete structure and the scope of application, thus every likely by
The corresponding amendment utilized and equivalent, belong to the apllied the scope of the claims of this utility model.
In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
