Description
Technical field
The present invention relates to a kind of device for peeling, specifically force return structures.
Background technology
When mold work, punch-pin fix bar is slided along angled-lift splits inclined-plane, resistance when spring overcoming workpiece backhaul.It is working
In often will appear the excessive punch-pin of resistance can not backhaul, workpiece be stuck on punch-pin can not discharging the problem of.
Invention content
The purpose of the present invention is to provide a kind of pressure return structures, which controls the stroke of punch-pin, solution by hinge
Punch-pin of having determined be stuck on punch retainer can not backhaul the problem of, ensure that the normal discharging of workpiece, improve working efficiency.
The technical scheme adopted by the invention to solve the technical problem is that：Return structures, including punch-pin, punch-pin are forced to be fixed
Bar, hinge, angled-lift splits, angled-lift splits fixed plate and punch retainer, the punch-pin is connected by screw with punch-pin fix bar, described
Punch-pin fix bar is connected through the hinge with angled-lift splits, and the angled-lift splits are fixed with angled-lift splits fixed plate by screw, the hinge
One end be equipped with and be equipped with pin hole with the fixed mounting hole of punch-pin fix bar, the other end of hinge, roller pin is equipped in the pin hole,
The pin hole of the hinge end section be a slot hole, the stroke of the length limitation punch-pin of slot hole, prevent workpiece block can not discharging,
The punch retainer is equipped with the hole that card puts guide sleeve, described to lead the rear portion for being set on punch-pin fix bar, can prevent
Only punch-pin fix bar is in direct contact friction with punch retainer, and guide sleeve can be replaced periodically, and punch retainer is not easy more
It changes,
The free end of fixing screws is connect after passing through hinge one end mounting hole with punch-pin fix bar, and the free end of roller pin is worn
Connect with angled-lift splits top after crossing pin hole, hinge rotate pivot pin swing, control punch travel,
When mold is opened, punch retainer floats under the action of the spring, and punch-pin and punch-pin fix bar are along punch retainer
Sliding, hinge are fixed on by fixing screws in punch-pin fix bar, and the pivot pin that rotates is swung, when pivot to another dead point,
Punch-pin can not follow punch retainer to continue to slide, and punch-pin is less than punch retainer, and workpiece will not be stuck on punch-pin, realize all
The demoulding of punch-pin ensure that the discharging of workpiece is smooth.
The beneficial effects of the invention are as follows：
1, the structure is connected through the hinge punch-pin fix bar and angled-lift splits, since hinge controls the stroke of punch-pin, so
Can solve the problems, such as punch-pin be stuck on punch retainer can not backhaul, force punch-pin backhaul to ensure that the normal discharging of workpiece, carry
High working efficiency.
2, due to being equipped with guide sleeve on punch retainer, lead being set on the rear portion of punch-pin fix bar and can prevent punch-pin from fixing
Bar is in direct contact friction with punch retainer.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram of hinge in the present invention；
Fig. 3 is the free state structural schematic diagram of the present invention；
Fig. 4 is in working condition schematic diagram.
In figure：1 punch-pin, 2 punch-pin fix bars, 3 screws, 4 hinges, 5 roller pins, 6 mounting holes, 7 angled-lift splits, 8 angled-lift splits are solid
Fixed board, 9 punch retainers, 10 guide sleeves, 11 pin holes.
Specific implementation mode
The pressure return structures of the present invention are described in detail below with reference to Figure of description.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, pressure return structures of the invention, structure include punch-pin 1, punch-pin fix bar
2, hinge 4, angled-lift splits, angled-lift splits fixed plate 8 and punch retainer 9, the punch-pin 1 are connected with punch-pin fix bar 2 by screw 3
It connects, the punch-pin fix bar 2 is connect with angled-lift splits 7 by hinge 4, and the angled-lift splits 7 are solid by screw with angled-lift splits fixed plate 8
Fixed, one end of the hinge is equipped with is equipped with pin hole 11, the pin with the fixed mounting hole 6 of punch-pin fix bar, the other end of hinge 4
Roller pin 5 is equipped in hole.
The punch retainer 9 is equipped with the hole that card puts guide sleeve 10, and the guide sleeve 10 is arranged after punch-pin fix bar 2
Portion can prevent punch-pin fix bar 2 to be in direct contact friction with punch retainer 9, and guide sleeve can be replaced periodically, and punch-pin is fixed
Plate is not easy to replace.
The free end of fixing screws is connect after passing through 4 one end mounting hole of hinge with punch-pin fix bar 2, the freedom of roller pin 5
End connect with 7 top of angled-lift splits after pin hole, hinge 4 rotate pivot pin 5 swing, control 1 stroke of punch-pin.
The pin hole of 4 end of the hinge is a slot hole, and the stroke of the length limitation punch-pin of slot hole ensures in free state
When, punch travel is no more than the stroke of punch retainer, ensures all demouldings, preventing workpiece from blocking can not discharging.
When mold is opened, punch retainer floats under the action of the spring, and punch-pin and punch-pin fix bar are along punch retainer
Sliding, hinge are fixed on by fixing screws in punch-pin fix bar, and the pivot pin that rotates is swung, when pivot to another dead point,
