Description

A kind of mould for thin material punching press

Technical field

The utility model relates to a kind of mould for thin material punching press, relate in particular to a kind of for thin material is pulled draw the material mechanism, belong to field of mechanical technique.

Background technology

Some long material can need material is transmitted when using punch press to carry out punching press usually, and the feed mechanism of traditional punch press has 2 kinds, and a kind of is to adopt idler wheel mechanism to transport material, and another kind is to adopt clip mechanism to transport material.These two kinds of feed mechanisms are fit to transport the above material of 0.1mm.The mistake problem easily occurs when transporting the following material of 0.1mm.As shown in Figure 1, on existing punch press, adopt 5 pairs of strips of feeder 1 to carry out feeding, strip 1 constantly travels forward by guide plate 4, because material is too thin, when mould 3 longer, the probability that misdelivery occurs is larger, because 5 ends at mould 3 of feeder, if die length is longer, in case the intensity of material self can not be born the feeding power that feeder 5 delivering belts apply, strip can produce the phenomenon that arches upward for one section 6.Break in this case, and easily mould parts.

The utility model content

The purpose of this utility model solves the problems of the technologies described above, and proposes a kind of mould that is used for thin material punching press that draws material mechanism that has.

The utility model is achieved through the following technical solutions.

a kind of mould for thin material punching press, comprise, counterdie, and draw and expect mechanism, offer aperture on described thin material both sides are even, described drawing expects that mechanism is arranged at the discharging opening of mould strip, comprise and draw the material base, the described material base that draws is fixed on counterdie, draw on the material base and offer rectilinear orbit, the mobile slide block that is provided with in described rectilinear orbit, be fixed with one on described slide block and draw material piece and spring, the described end of material piece that draws is fixed on slide block by alignment pin, described spring props up described other end bottom of drawing the material piece, the described top of material piece of drawing is arranged in the hole of thin material,

Described drawing expects that mechanism comprises that also one is used for limiting the retaining pin that thin material falls back, and described retaining pin presses down it by spring, and the bottom of retaining pin is through in the hole of thin material, and described retaining pin is arranged on the front upper place of drawing the material piece;

Described slide block is arranged on drift below, and the upper end is provided with the oblique angle, and described drift presses down and promotes slide block and move to feedstock direction;

Be connected by baffle plate fixing on spring and counterdie on the tail end side of described slide block, described drift moves up and down between the gap of baffle plate and slide block.

The beneficial effects of the utility model are mainly reflected in: adopted the mode at strip one layback material, solved the feeding mechanism for punch press situation that generating material can not transport when transporting thickness less than the material of 0.1mm, avoided transporting the situation that misdelivery occurs material fully, improved greatly the stability of producing, make the continuous punching of thin material become stable, also greatly reduce the lathe cost simultaneously.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described:

The utility model has disclosed a kind of mould for thin material punching press, comprises upper and lower mould, and draws and expect mechanism, offers aperture on described thin material both sides are even.In conjunction with Fig. 2, shown in Figure 3, described drawing expects that mechanism is arranged at the discharging opening of mould strip, comprises and draws material base 6, and the described material base 6 that draws is fixed on counterdie 2 by draw-in groove 11.

Draw on material base 6 and offer rectilinear orbit (meaning not shown in the figures), the mobile slide block 7 that is provided with in described rectilinear orbit, be fixed with one on described slide block 7 and draw material piece 8 and spring 10, the described end of material piece 8 that draws is fixed on slide block 7 by alignment pin 12, described spring 10 props up described other end bottom of drawing material piece 8, and the described top 81 of material piece 8 of drawing is arranged in the hole of thin material.

Described drawing expects that mechanism comprises that also one is used for limiting the retaining pin 4 that thin material falls back, and described retaining pin 4 presses down it by retaining spring 5, and the bottom of retaining pin 4 is through in the hole of thin material, and described retaining pin 4 is arranged on the front upper place of drawing material piece 8.

Also be fixed with a baffle plate 9 on described counterdie 2, described baffle plate 9 is arranged on the tail end that draws material base 6, described drift 3 is the up and down punching press between baffle plate 9 and slide block 7, concrete refers to, when the mould closure, drift 3 presses down, and promotes slide block 7 and moves to feedstock direction, due to the existence of retaining pin 4, make strip 17 can not bend due to the motion of slide block 7 or move back and send.

in conjunction with shown in Figure 4, spring 10 is loosening with a side of drawing material piece 8, draw the top 81 of material piece 8 to withdraw from from the first hole 110, and driven to the second hole 111 motions by slide block 7, top 81 is through in the second hole 111, when mould separates, drift 3 leaves slide block 7, retaining pin 4 eases out in the hole, the spring that slide block 7 is connected with baffle plate by the rear end (meaning not shown in the figures) moves to the discharging direction, return to initial position, drive draws material piece 8 toward the motion of discharging direction, because the upper end 81 of drawing material piece 8 is stuck in the second hole 111 of strip 17, namely driving thin material pulls to discharging opening, and then reach the purpose that strip transports.

Can be smoothly during for drift 3 punching press slide block 7 be promoted, described slide block 7 offers an oblique angle, the cooperation that described oblique angle is relative with drift 3 in the contact-making surface upper end with drift.

The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection domain of the present utility model.
