The specific embodiment

For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:

As accompanying drawing 1-5, a kind of Bending Mould, the auxiliary block 7 that comprises cope match-plate pattern 1, lower bolster 2 and product 8 location, product 8 is positioned on the mould by auxiliary block 7 according to product 8 shapes, also can on product 8, fabrication hole be set, on auxiliary block 7, cooperate fabrication hole that alignment pin is set product 8 is positioned on the mould.Bending slide block drift 31 is housed on cope match-plate pattern 1, bending slide block drift 31 two bottom sides are provided with the inclined-plane, the bending slide block 33 that bending counterdie mold insert 34, Bending punch assembly 32 is housed on lower bolster 2 and cooperates and drive 32 work of Bending punch assembly with bending slide block drift 31.Form a dead slot between the bending counterdie mold insert 34, Bending punch assembly 32 places in the dead slot and can move along dead slot; Bending punch assembly 32 comprises product is carried out the holding pad 321 of binder and the fixing Bending punch fixed head 323 of Bending punch 322; Bending resetting means 4 also is housed on lower bolster 2.Bending slide block drift 31 1 sides are Bending punch assemblies 32, and opposite side is a bending resetting means 4.Bending resetting means 4 comprise the bending that cooperates with bending slide block drift 32 reset slide block 41, with bending the reset push rod 42 and be contained in reset bending back-moving spring 43 on the push rod 42 of bending of bending that slide block 41 cooperates that resets.Bending slide block 33, the bending contact-making surface that slide block 41 contacts with bending slide block drift 31 that resets cooperates with bending slide block drift 31 inclined-planes.

Crowded slide block drift 51 also is housed back on the above-mentioned cope match-plate pattern 1, the crowded slide block 53 that returns of forcing down mould mold insert 54, cooperate with time crowded slide block drift 51 and drive back crowded punch-head assembly 52 work also is housed back on the lower bolster 2, return to force down and form a dead slot between the mould mold insert 54, return crowded slide block 53 and place in the dead slot and can move, crowded punch-head assembly 52 is housed back returning on the crowded slide block 53 along dead slot.

Wherein, return crowded punch-head assembly 52 and comprise time crowded drift fixed head 521 that is loaded on back on the crowded slide block 53 and the crowded drift 522 that returns that is fixed in back on the crowded drift fixed head 521.Above-mentioned returns crowded slide block drift 51 length greater than bending slide block drift 31 length, guarantees that product carries out with returning can cooperate in the crowded operation in bending; The above-mentioned contact-making surface that returns crowded slide block drift 51 close products is the inclined-plane 511 of certain angle, returns crowded slide block 53 and cooperates with inclined-plane 511 with the contact-making surface 531 that time crowded slide block drift 51 contacts.On lower bolster 2, crowded resetting means 6 also is housed back near returning crowded slide block 53, return crowded resetting means 6 comprise with returning of returning that crowded slide block drift 51 cooperates squeeze the slide block 63 that resets, with return reset push rod 62 and be contained in back time crowded back-moving spring 61 on the crowded push rod 62 that resets of squeeze that the slide block 61 that resets cooperates time crowded.

Add man-hour, at first, behind the processed product location, starting lathe presses down, bending slide block drift 31 presses down, bending slide block drift 31 contacts with bending slide block 33 and the bending slide block 41 that resets respectively, promoting bending slide block 33 on one side moves to product 8 places, promoting on one side the bending slide block 41 that resets moves backward, bending slide block drift 31 continues to glide, and the bending slide block 41 that resets continues to move backward to press to bending back-moving spring 43, and the slide block of bending simultaneously 33 promotes holding pads 321 and moves forward and compress the product outside, then Bending punch 322 is finished the bending action, needs bending part to be bent into arc chord angle in the product outside.In addition, in the process that bending slide block drift 31 presses down, return crowded slide block drift 51 and also carrying out pressing action, returning crowded slide block drift 51 contacts with time crowded slide block 63 that resets with time crowded slide block 53 respectively, promoting back crowded slide block 53 on one side moves to product 8 places, promoting back to squeeze the slide block 63 that resets on one side moves backward, returning crowded slide block drift 51 continues to glide, returning the crowded slide block 63 that resets also continues to move backward to press to back crowded back-moving spring 61, return crowded slide block 53 and continue to promote go back to the inboard, fillet place that crowded drift 522 moves forward the extruded product bending, the arc chord angle of product outside bending is squeezed into wedge angle, finishes the extruding action.At last, lathe is up, it is up to drive back crowded slide block drift 51 and bending slide block drift 31, and return squeezing resets slide block 63 and return crowded slide block 53 resets under the effect of returning crowded back-moving spring 61, and reset slide block 41 and bending slide block 33 of bending resets under the effect of bending back-moving spring 43.As repeatedly above-mentioned, on a machine, simultaneously product 8 is carried out bending and returns crowded work, finish the whole manufacturing procedure of bending part product.

The utility model has increased time extruding mold in the basic factory of original Bending Mould, realized single unit two stations of product are operated simultaneously, product is finished bending and is returned crowded work at same position, product orientation accuracy height, product quality is more reliable, has also improved the speed of production and the production efficiency of product simultaneously, has also saved a large amount of human resources, lower production cost, improved the market competitiveness of enterprise.

The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
