Abstract
The utility model relates to the technical field of stamping dies, in particular to a mechanism for preventing a workpiece or scrap material from ascending. The mechanism comprises a jigger pin and a flexible assembly connected with the jigger pin, wherein the jigger pin is arranged at the interior of a die convex die; under the elasticity effect of the flexible assembly, the front end of the jigger pin is exposed out of the front end surface of the convex die; during blanking, the convex die enters a concave die from top to bottom to complete the blanking; during blanking, the flexible assembly is compressed by the jigger pin so as to be flush with the front end surface of the convex die all the time; after the blanking is completed, the convex die begins to rise upwards under the driving of a die holder; and under the elasticity effect of the flexible assembly connected with the jigger pin, the blanking workpiece or scrap material is separated from the convex die to enter a convex die opening. The mechanism effectively solves the problem that the workpiece or scrap material is ascended during the stamping process, and is simple in structure and reliable.
Description
Technical field
The utility model relates to the Stamping Die Technology field, particularly a kind of mechanism that prevents that product or waste material from rising.
Background technology
Mould is assembled by each parts, during punching press, stamps out satisfactory metalwork by the upper die and lower die cooperation.
Mould is wanted the energy operate as normal, and the reliability of discharging is very important.Generally speaking, big skeletal waste we can utilize stripper to implement discharging, the fritter product that stamping-out gets off or waste material then utilize the gravity effect that it is fallen down from die, but it is also unreliable sometimes by the gravity effect, especially under the situation of high speed stamping, owing to reasons such as speed is fast, die point magnetization, may cause product or waste material to rise from the die mouth.If the product or the waste material that rise stick on the punch cutting edge plane, can influence operate as normal, when serious even can mold damage and forcing press, therefore to avoid the generation of this phenomenon, the mechanism that prevents product and waste material rising reliably just must be arranged.
At present, when general big part punching out, week leftover bits and pieces of material discharging can adopt patrix to install elastic tripper additional, and middle waste material can adopt the knockout rod in the forcing press, as shown in Figure 1, for the waste material in the middle of preventing is bonded on the punch 1, in punch 1, be provided with two knockout rods 2, but utilize knockout rod 2 dischargings to make that mould structure is complicated, cost rises.And 2 of knockout rods are applicable to the big part of stamping-out, and when at high speed stamping porous finding, punch 1 less centre can't arrange knockout rod 2, therefore are unsuitable for adopting knockout rod 2 to carry out discharging.
The utility model content
The utility model is in order to solve diel when the punching press finding, can't adopt knockout rod to prevent that product or waste material rising from causing product or waste material to stick on the punch cutting edge plane, influence the mould operate as normal, even the problem of mold damage, and a kind of mechanism that prevents that product or waste material from rising that provides.
For reaching above-mentioned functions, the technical scheme that the utility model provides is:
A kind of mechanism that prevents that product or waste material from rising comprises jigger pin and the elastomeric element that is connected with described jigger pin, and described jigger pin is arranged at mould punch inside, and under the effect of described elastomeric element elastic force, the front end of described jigger pin exposes the punch front end face.
Preferably, described elastomeric element is spring.
Preferably, the front end of described jigger pin is spherical.
Preferably, the diameter of described jigger pin is 2～6mm.
The beneficial effects of the utility model are: a kind of mechanism that prevents that product or waste material from rising, comprise jigger pin and the elastomeric element that is connected with described jigger pin, described jigger pin is arranged at mould punch inside, under the effect of described elastomeric element elastic force, the front end of described jigger pin exposes the punch front end face; When stamping-out, punch enters die from top to bottom, finish stamping-out, described jigger pin compresses described elastomeric element when stamping-out, make the front end face of jigger pin keep concordant with the punch front end face all the time, after stamping-out finished, punch began up lifting under the drive of die holder, stamping-out product or waste material separate to enter the die mouth with punch under the effect of the elastomeric element elastic force that is connected with described jigger pin; The utility model has solved the problem that in punching course product or waste material rise effectively, and simple in structure, reliable.
Description of drawings
Fig. 1 is for adopting the structural representation of the stamping die that has knockout rod now;
Fig. 2 is structural representation of the present utility model;
Structural representation when Fig. 3 is the utility model stamping-out.
The specific embodiment
Be further elaborated below in conjunction with accompanying drawing 2 and the utility model of Fig. 3:
The mechanism that prevents product or waste material rising as shown in Figure 2 comprises jigger pin 3 and the elastomeric element 4 that is connected with jigger pin 3, and jigger pin 3 is arranged at mould punch 1 inside, and under the effect of elastomeric element 4 elastic force, the front end of jigger pin 3 exposes punch 1 front end face.In the present embodiment, elastomeric element 4 adopts the spring of cost performance height and stable performance, and certainly in actual use, we also can adopt cylinder or elastic sheet rubber etc. according to actual needs.
The front end of jigger pin 3 exposes the height of punch 1 front end face and the diameter of jigger pin 3, can follow border processing factually to adjust, and the height that in general exposes is 2～6 times of stamping-out material thickness, the preferred 2～6mm of the diameter of jigger pin 3.
In the present embodiment, for making jigger pin 3 starts more smooth and easy, the front end of jigger pin 3 adopts spherical shape.
As shown in Figure 3, when stamping-out, punch 1 enters die (not shown among Fig. 3) from top to bottom, effect bottom knockout pin 3 elasticity of compression parts 4 at the resistance of material 5, make the front end face of jigger pin 3 keep concordant with the front end face of punch 1 all the time, after stamping-out finished, punch 1 began up lifting under the drive of die holder 6, stamping-out product or waste material 51 separate to enter die mouth (not shown among Fig. 3) with punch 1 under the effect of elastomeric element 4 elastic force that are connected with jigger pin 3.
The above embodiment, it is preferred embodiments of the present utility model, be not to limit practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, all should be included in the utility model patent claim.
