Abstract

The utility model relates to a bending die with a novel swing block structure, comprising two swing blocks which are movably arranged on a lower die plate of the die, the two swing blocks are respectively provided with a bending face which can be matched with punching head bending products of the die, a lower die base of the die is further provided with two second first restoration springs whose other ends are respectively pressed on one lateral sides of the two swing blocks, wherein the die further comprises an inlet block which is movably arranged between the two swing blocks, and the two opposite sides of the two swing blocks are further provided with a first slanting face, the inlet block is provided with two second slanting faces which can be matched with the two first slanting faces. In addition, the lower die base is further provided with a second restoration spring whose other end is pressed on the inlet block. The utility model can easily restore the swing blocks through the matching effect of the inlet block and the two swing blocks, which avoids repairing cost of easy breaking of a pressing block in the conventional technique.

Description

The Bending Mould of the novel centering block structure of tool

Technical field

The utility model relates to a kind of Bending Mould, relates in particular to a kind of Bending Mould of tool centering block structure.

Background technology

The punching press of conventional products bending, stripper plate does not have the space and does and head into piece in advance in general small mould, just adopts stripper plate directly to come die pressing product that centering block is resetted, and centering block is stuck easily like this; In addition, head into piece in advance, remove to press centering block with heading into piece in advance if adopt on stripper plate, to be provided with, need on mold and punching head, step down, and this head in advance piece at the stress point of centering block on the inclined-plane, this heads into piece in advance and just is easy to break like this, influence manufacturing schedule, and increased the mold repair expense thus.

Summary of the invention

In view of the above problems, the utility model purpose is to provide the Bending Mould of the novel centering block structure of a kind of tool, and this Bending Mould need not use and head into piece in advance this centering block is resetted, and can avoid owing to head into the mold repair expense that piece fractures easily and brings in advance.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme: the Bending Mould of the novel centering block structure of a kind of tool, this mould comprises two centering blocks, this two centering block is movably set in this lower mould plate, this two centering block has a folding surface respectively, this folding surface can cooperate this mold and punching head bending product, also be provided with 2 first back-moving springs on this lower mould seat, this 2 first back-moving spring other end contacts at bottom one side of this two centering block respectively, it is characterized in that, this mould also comprises into piece, this is gone into piece and is movably set between this two centering block, relative two sides of this two centering block also are respectively arranged with one first inclined plane, this is gone into piece and has 2 second inclined planes, and this 2 second inclined plane and this 2 first inclined plane can cooperatively interact, in addition, also be provided with second back-moving spring on this die shoe, this second back-moving spring other end then contacts at this and goes on the piece.

Than routine techniques, the utility model is gone into piece by this is set, and, this centering block can be resetted easily by this mating reaction of going into second, first inclined plane of piece and this two centering block, avoided owing to head into the mold repair cost that piece fractures easily and brings in advance in the routine techniques.

Fig. 2 is the schematic perspective view of the Bending Mould matched moulds of the novel centering block structure of the utility model tool.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

Please cooperate consult shown in Figure 2, the utility model is used for product 3000 is carried out pressing and bending, the utility model comprises a upper bolster 1000, one die shoe 2000, and fixedly connected upper padding plate 1100, train wheel bridge 1200, fixedly connected baffle plate 1300, stripper plate 1400, fixedly connected lower bolster 2100, lower bolster 2200, this upper padding plate 1100 is fixedly connected on this upper bolster 1000, this lower bolster 2200 is fixedly connected on this die shoe 2000, this baffle plate 2200 is movably connected on this train wheel bridge 1200, the utility model also comprises two drifts 1110, this two drift 1110 is arranged on this upper padding plate 1100, and the other end of this two drift 1110 then activity is placed through this train wheel bridge 1200, on baffle plate 1300 and the stripper plate 1400.

The utility model also comprises two centering blocks 2110, this two centering block 2110 is movably set in this lower bolster 2100, this two centering block 2110 has a folding surface 2111 respectively, this two folding surface 2111 can cooperate this drift 1110 pressing and bending products 3000, also be provided with 2 first back-moving springs 2010 on this die shoe 2000,2 first back-moving springs, 2010 other ends contact at bottom one side of this two centering block 2110 respectively, relative two sides of this two centering block 2110 also are respectively arranged with one first inclined plane 2112, also be provided with one between this centering block 2110 and go into piece 2120, this is gone into piece 2120 and has 2 second inclined planes 2122, this 2 second inclined plane 2122 and this 2 first inclined plane 2112 can cooperatively interact, in addition, also be provided with second back-moving spring 2020 on this die shoe 2000, these second back-moving spring, 2020 other ends then contact at this and go on the piece 2120.

So, during this mould matched moulds, this stripper plate 1400 descends, this product 3000 is pressed down, this product 3000 is promptly oppressed this and is gone into piece 2120 and descend, and first inclined plane 2112 by 2 second inclined planes, 2122 these two centering blocks 2110 of extruding allows this two centering block 2110 progressively reset thereby this goes into piece 2120, thereby, when this stripper plate 1400 dropped on this lower bolster 2100 of conflicting, this two centering block 2110 resetted fully; Then, this die shoe 1000 continues to descend, and this two drift 1110 will be conflicted the dogleg section of this product 3000 on the folding surface of this two centering block 2110, and as shown in Figure 2, this product 3000 has promptly been finished pressing and bending.

During this mould die sinking, this die shoe 2000 rises, this two drift 1110 at first breaks away from this product 3000, then this stripper plate 1400 rises, this is gone into, and piece 2120 rises under the effect of the elastic-restoring force of this second back-moving spring 2020 and this product 3000 of conflicting rises to play the effect of taking off material, and this two centering block 2110 is also finished homing action under the effect of the elastic-restoring force of this first back-moving spring 2010.

To sum up, the utility model is gone into piece 2120 by this is set, and go into the mating reaction on piece 2120 and second, first

inclined plane

2122,2112 of this two centering block 2110 by this, this centering block 2110 can be resetted easily, avoided owing to head into the mold repair cost that piece fractures easily and brings in advance in the routine techniques.

The above only is a preferable possible embodiments of the present utility model; be not so promptly limit to claim of the present utility model; so the equivalent structure that every utilization the utility model specification and accompanying drawing content are done changes, and all is contained in the protection domain of the present utility model.
