Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.
It is as shown in figs 1-9 a kind of boss part punching die described in the utility model, including upper mold 1 and lower die 2, institute Upper mold 1 is stated to include the upper die holder 11 set gradually from the top down, upper padding plate 12, upper clamp plate 13, take off backboard 14 and stripper plate 15, on Die holder 11, upper padding plate 12 and upper clamp plate 13 are bolted on together, and de- backboard 14 and stripper plate 15 are bolted on Together.Several reset springs 131 are installed between upper clamp plate 13 and de- backboard 14, after upper clamp plate 13 moves downward, are resetted Spring 131 can push de- backboard 14 and stripper plate 15 open.Lower die 2 includes the lower die being bolted on from the top down together Plate 23, lower bolster 22 and lower die holder 21.Baltimore groove (not identifying in figure) is machined in lower template 23.Baltimore groove can be Run through the through slot of lower template 23 down.Left and right is detachably secured wedge block 3 there are two installations relatively in baltimore groove, above-mentioned The lozenges of two wedge blocks 3 is oppositely arranged, and forms up big and down small wedge-shaped opening (as shown in Figure 1).Left and right is opposite in wedge-shaped opening There are two sliding blocks 4 for installation.Two sliding blocks 4 slide up and down with the wedge block 3 of corresponding side connect respectively.It is specific as shown in figure 9, It is machined with sliding slot 31 on the lozenges of two wedge blocks 3, the side of two 4 opposite exterior lateral sides of sliding block is similarly lozenges, and Guide rail 41, the sliding connection of sliding slot 31 of guide rail 41 and corresponding side are machined on its lozenges.Above-mentioned two 4 phase of sliding block To perforative half slot is machined with respectively along the vertical direction on the side of inside, pass through moving up and down for sliding block 4, two half slots It is combined into through-hole, through-hole is stepped hole, forms (as shown in Figure 4) by small cylindrical opening 5 and big cylindrical hole 51.Small cylindrical opening 5 In the top of big cylindrical hole 51, the diameter of small cylindrical opening 5 is less than the diameter of big cylindrical hole 51.The diameter and boss of small cylindrical opening 5 91 outer diameter of boss of part 9 matches.By said structure design, when sliding block 4 moves down, small cylindrical opening 5 can be by boss The boss 31 of part 9 wraps.
It is fitted with vertical bar 6 in above-mentioned big 51 internal clearance of cylindrical hole, vertical bar 6 is fixedly linked with lower bolster 22.Vertical bar 6 Top is machined with punching 61, the formed punch 121 to match with punching 61 is equipped on upper clamp plate 13, the lower end of formed punch 121 can be successively Activity passes through de- backboard 14, stripper plate 15 and small cylindrical opening 51.Wherein the outer diameter of vertical bar 6 is greater than the diameter of small cylindrical opening 51, convex 91 bottom of boss of platform part 9 can be pushed against the top of vertical bar 6.The diameter of punching 61 is less than the diameter of small cylindrical opening 51.Formed punch 121, small cylindrical opening 51, big cylindrical hole 52, vertical bar 6 and punching 61 are located on same central axis.It is located at punching 61 in vertical bar 6 Lower section be machined with material-dropping hole 62, material-dropping hole 62 is connected with punching 61, and blanking channel 211, blanking are machined on lower die holder 21 Channel 211 is connected with material-dropping hole 62.The diameter of material-dropping hole 62 is gradually increased from top to bottom.
The bottom for sequentially passing through baltimore groove, lower template 23,22 and of lower bolster are mounted in the bottom part down of two sliding blocks 4 The guide channel (not identified in figure) of lower die holder 21.It is up and down in guide channel that mandril 6 is installed.The upper end of mandril 6 is supported Lean against the bottom of sliding block 4.The bottom thread of guide channel is connected with set screw 72, be located in guide channel set screw 72 with Reset spring 71 is installed between mandril 7.
For processing can be punched out to the bevelled boss part 9 of tool as shown in Figure 10 and Figure 11, in stripper plate 15 On stripper plate mold insert 151 is installed, be machined on stripper plate mold insert 151 formed punch 121 it is movable by channel.Sliding block 4 and wedge The upper surface of shape block 3 has been processed towards unidirectional first inclined-plane 8, and the direction on the first inclined-plane 8 can be any direction, The lower surface of stripper plate mold insert 151 is machined with second inclined-plane 81 corresponding with the first inclined-plane 8.
In non-punching, as shown in figure 9, the top of sliding block 4 is higher by wedge shape under the action of mandril 7 and reset spring 71 The top of block 3.In punching, sliding block 4 is oppressed in the lower surface of stripper plate mold insert 151, makes it into wedge-shaped opening.When sliding block 4 On half slot when being combined into through-hole (namely stepped hole), the upper surface of two sliding blocks 4 and the upper surface of two wedge blocks 3 are homogeneous Concordantly.By rationally designing the height of vertical bar 6, the top of vertical bar 6 is just resisted against at the circular bead surface in stepped hole (i.e. big cylinder The upper surface in hole 51).In addition, the boss height of boss part 9 should be designed as it is consistent with the height of small cylindrical opening 5.
When work, the boss 91 of boss part 9 is placed between the half slot of two sliding blocks 4, the matrix of boss part 9 92 lower surface and the first inclined-plane 8 of sliding block 4 fit.When punching press, upper mold 1 is moved down (when molding), stripper plate mold insert 151 Lower surface be affixed to merge with the upper surface of the matrix 92 of boss part 9 and apply pressure, sliding block 4 and boss part 9 are by moving down It is dynamic, in the mobile wedge-shaped opening of sliding block 4, the upper table of sliding block 4 and the upper surface flush of wedge block 3.During sliding block 4 moves down, Half slot on sliding block 4 is mobile to relative inner and is combined into small cylindrical opening 5, so that small cylindrical opening 5 is by the boss of boss part 9 31 wrap.Formed punch 121 continues to move down and be punched out to boss part 9, and the waste material of punching is from material-dropping hole 62 to moving down It is dynamic, and transported out eventually by blanking channel 211.After the completion of punching, upper mold 1 is moved up and is separated with boss part 9, sliding Block 4 is jacked up under the action of mandril 7 and reset spring 71, and for sliding block 4 when moving up, the half slot of sliding block 4 is to relatively outside Side is mobile, to unclamp the boss 91 of boss part 9.So boss part 9 is jacked up simultaneously.Existed by rationally designing sliding block 4 Spacing separated outward when moving up, boss part 9 can move in left-right direction when being jacked up from above-mentioned separated spacing It sends out, without taking out boss part 9 from the top of sliding block 4, thus multiple 9 energy of boss part on a billot band Enough realize continuous punching processing.
The present embodiment can be by 9 boss 91 of boss part by the small cylindrical opening 5 of 4 half slot composition on two sliding blocks Outer wall banding effectively prevent 91 hole wall spalling of boss when punching to open.Boss part 9 can be unclamped automatically after the completion of punching press, The processing method of boss part 9 is coherent, high production efficiency, is suitble to continuous production processing.In addition, by being arranged in the lower section of punching Waste material after punching can continuously be discharged, further improve production efficiency by the material-dropping hole 62 being connected.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass, is also included in the patent protection scope of the utility model.
