Abstract
The invention discloses a stamping mechanism with high planeness. The stamping mechanism comprises an upper die and a lower die which are mutually matched, wherein the upper die and the lower die are respectively provided with a stripper plate and a floating material block which are used for pressing materials; a floating material ejector rod by which the floating material block moves is arranged at the lower end of the floating material block; the lower side of the floating material ejector rod is connected with a spring; a male die is arranged on the upper die; a return part is arranged on the periphery of the male die; the upper side of the return part is connected with an ejector rod; an ejector rod spring is connected to the other end of the ejector rod; a product female die formed by an inner cavity of a material punching head is arranged on the lower die; a product return part is also arranged in the inner cavity of the material punching head; and a return assembly for ejecting the product is arranged below the female die. The stamping mechanism has the benefit that the problem that thin materials and multilayer materials requiring high planness are instable in stamping is solved. The maintenance frequencies of the dies are remarkably reduced, the production is stable and the qualified rate of products is increased; and during normal stamping, the qualified rate of the products approaches to 100 percent.
Description
Technical field
The present invention relates to a kind of punching mechanism, relate in particular to a kind of thin material punching mechanism that multilayer material or flatness are had relatively high expectations that is used for, belong to the Machining Technology field.
Background technology
In manufacturing, bicker often becomes requisite device.As shown in Figure 1, be bicker of the prior art.In the time of die-cut, the push rod 13 that is connected with spring 22 by an end moves upward buoyant piece 10, and stripper plate 11 compresses material 3 with buoyant piece 10; Material 3 touches drift 12, and drift 12 is punched into die 20 with material 3, and product release link 23 compresses product 4 all the time; Mould is during to bottom dead centre; Drift does not dash and wears material, and when stripper plate 11 and buoyant piece were opened in 10 minutes, product release link 23 ejected die 20 with product.After ejecting product, product 6 carries out blanking with material 3 to next worker station.
But when running into relatively thin material, also carry out die-cutly in this way, product 6 will be stuck in the situation that die 20 the insides cause its generation to reset.Simultaneously; Towards double layer material the time, find original coherent product, with this bicker after die-cut; Because the die-cut section of product 6 has received the influence of the frictional force of die 20 inwalls when being ejected by product release link 7, have slight gap between the double-deck material.
So this structure of the prior art is for thin material, multilayer material also is not suitable for.Not only punching press is unstable, and production efficiency is low; And the frequency of mold repair is high, and product percent of pass is low, needs all to detect waste great amount of manpower and material resources.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, propose a kind of high flatness punching press that can keep thin material and multilayer material punching mechanism.
The object of the invention will be achieved through following technical scheme:
A kind of punching mechanism of high flatness comprises the upper and lower mould that cooperatively interacts, and said upper and lower mould is respectively arranged with stripper plate and the buoyant piece that is used to compress material; Said buoyant piece lower end is provided with the buoyant push rod that makes its motion; The below of said buoyant push rod is connected with spring, it is characterized in that: said patrix is provided with punch, and the periphery of said punch is provided with reset components; The reset components top is connected with push rod, and the other end of said push rod is connected with push rod spring;
Said counterdie is provided with the product die, and said product die is formed by material drift inner chamber, and the inner chamber of said material drift also is provided with the product reset components, and the below of said die is provided with the reset assembly that is used to eject product.
Preferably, said reset assembly comprises a product release link, and said product release link connects through the push rod that resets that the bottom is connected with spring.
Preferably, said push rod is provided with two at least, and the other end of said push rod all is connected with push rod spring.
Beneficial effect of the present invention is mainly reflected in: adopt this structure to carry out punching press, the material around product and the product all has a relative power traction all the time, has solved demanding thin material of flatness and the instable problem of multilayer material punching press.When adopting the actual production of this mechanism, the situation of material separation can not appear in double layer material, the phenomenon that product card die bullet does not come out do not occur because product is thin yet, when product ejects die, can not be out of shape.The number of times of mold repair significantly reduces, and produces and stablizes, and improves the qualification rate of product, during punching press normally, and product percent of pass nearly 100%.

Fig. 2 is a structural representation of the present invention.
The specific embodiment
The invention provides a kind of punching mechanism of high flatness, as shown in Figure 2, comprise the upper and lower mould that cooperatively interacts, said upper and lower mould is respectively arranged with the stripper plate 31 and buoyant plate 30 that is used to compress material.Said buoyant plate 30 lower ends are symmetrically arranged with two buoyant push rods 41 that make its motion, and the below of said buoyant push rod 41 all is connected with spring.Said patrix is provided with punch, and said punch periphery is a reset components, and said reset components compresses material in punching press, and the effect of taking off material is arranged behind die-cut finishing.The reset components top is connected with two push rods 42, and the other end of said push rod 42 all is connected with push rod spring 43.
Said counterdie is provided with the product die, and said die is formed by material drift 22, and is concrete, and the inner chamber of said material drift 22 is exactly the die of die-cut product, and the below of said die is provided with the reset assembly that is used to eject product.Concrete, said reset assembly comprises a product release link 23, said product release link 23 connects through the push rod 40 that resets that the bottom is connected with spring.
Operation principle of the present invention and process under the brief description:
After treating that die-cut material 10 places, stripper plate 31 compresses material 10 with buoyant plate 30, makes material 10 touch material drift 22.Punch continues to move downward, and when product drift 21 touches material 10, begins die-cutly, and product drift 21 advances in the die 22 to form products 20 with material 10 is die-cut.Meanwhile; Material around the material drift 22 die-cut products; At this moment, product 20 all receives the effect of the spring force of the push rod tail end of upper and lower mould separately with its material 10 on every side, and it is fine that the opposite power of upper and lower mould medi-spring makes that product 20 and material around combine.After stripper plate 31 and buoyant plate were opened in 30 minutes, product release link 23 ejected product 20, and release link 11 ejects waste material.Accomplish whole die-cut process.Because the push rod of product release link 23 is provided with spring, and cushioning effect is arranged when ejecting product, the phenomenon that product card die bullet does not come out can not appear yet for thin product, when product ejects die, can not be out of shape.
Adopt this structure to carry out punching press, the material around product and the product all has a relative power traction all the time, has solved demanding thin material of flatness and the instable problem of multilayer material punching press.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
