Application number be 201320556220.3 utility model mainly have additional stripper guide pillar and improve motor stamping quality, and punch retainer, punch and Die Design are mainly become to hold easily changeable structure by the present invention, make the motor stamping producing different profiles only need change punch retainer, punch, discharging rubber and die thus save the cost of making mould and shorten the cycle making mould.
Summary of the invention
The technical problem to be solved in the present invention is:
1. how to save the expense of making new die, man power and material;
2. how to shorten the cycle making mould.
Pin is with the problems referred to above, and the technical scheme that the present invention proposes is: a kind of replacing options of motor stamping single punch-die, and patrix comprises die shank, upper mould fixed plate, punch retainer, punch and discharging rubber; Counterdie comprises die, pressing plate and die shoe, when producing difform motor stamping, only need change punch retainer, punch, discharging rubber and die.
Further, together with punch retainer is bolted with upper mould fixed plate, only need unclamps bolt and just punch retainer, punch can be removed together with discharging rubber.
Further, punch and punch retainer are linked together by interference fits, and punch can take out from punch retainer and change.
Further, discharging rubber case is on punch, and discharging rubber case is wrapped in punch from surrounding, discharging rubber case directly can be extracted from punch.
Further, the cross section of die and pressing plate is all trapezoidal, and die and pressing plate form trapezoidal cooperation, and bolt also makes pressing plate cause horizontal extruding to die while being fixed on die shoe by pressing plate, be fixed on die shoe by die.
Further, unclamp just die to be taken out for bolt pressing plate is fixed on die shoe and change.
A kind of motor stamping single punch-die structure, mould bases is made up of die shank, upper mould fixed plate, pressing plate and die shoe; Movable mold is made up of punch retainer, punch, discharging rubber and die, when producing difform motor stamping, need not change mould bases, only need change movable mold.
Further, upper mould fixed plate is positioned at below die shank, together with upper mould fixed plate is bolted with die shank.
Further, punch retainer is positioned at below upper mould fixed plate, together with punch retainer is bolted with upper mould fixed plate.
Advantage of the present invention is:
1. can save the expense of making new die, man power and material;
2. can shorten the cycle making mould;
3. mould structure is simple, is convenient to installation and removal, changes parts simple and convenient.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the top view of counterdie of the present invention;
In figure: 1 die shank, 2 upper mould fixed plates, 3 punch retainers, 4 punch, 5 discharging rubbers, 6 dies, 7 pressing plates, 8 die shoes, 9 patrixes, 10 counterdies, 11 bolts.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the present invention:
Embodiment one
As shown in Figure 1, patrix 9 comprises die shank 1, upper mould fixed plate 2, punch retainer 3, punch 4 and discharging rubber 5; Counterdie 10 comprises die 6, pressing plate 7 and die shoe 8.Along with the development of motor industry, new motor stamping upgrades more and more faster, because new motor stamping is different, is always all again made by all mold components in patrix 9 and counterdie 10 to produce difform motor stamping in the past.For reducing cost and the time of the making of a complete set of new die, the present invention adopts new structure, makes die shank 1, upper mould fixed plate 2, pressing plate 7 and die shoe 8 form mould bases; Punch retainer 3, punch 4, discharging rubber 5 and die 6 form movable mold.When producing difform motor stamping, do not need to change mould bases, only need change movable mold just passable.
In the present invention, upper mould fixed plate 2 is positioned at below die shank 1, and upper mould fixed plate 2 and die shank 1 are linked together by bolt 11; Punch retainer 3 is positioned at below upper mould fixed plate 2, and punch retainer 3 and upper mould fixed plate 2 are linked together by bolt 11; Punch 4 is positioned at below punch retainer 3, and punch 4 and punch retainer 3 are linked together by interference fits.
When producing motor stamping, patrix 9, to when pressing down, under the shape constraining of punch 4 and die 6, can stamp out the motor stamping conformed to the shape of die 6 with punch 4.And patrix 9 is to when pressing down, discharging rubber 5 by die 6 upwards jack-up form certain deformation, now punch 4 stretches out discharging rubber 5; When patrix 9 is to rising, the deformation of discharging rubber 5 starts to restore, and is ejected downwards by motor stamping, completes discharging.Bore due to discharging rubber 5 is slightly less than punch 4, so discharging rubber 5 tightly can be wrapped in the surrounding of punch 4, just can be fixed on punch 4 without any need for auxiliary parts.
When the difform motor stamping of production, when needing different moulds, only need by not shown in FIG. with the bolt 11(of upper mould fixed plate 2 for connection punch retainer 3) unclamp and just punch retainer 3, punch 4 can be removed together with discharging rubber 5.Because discharging rubber 5 is directly enclosed within punch 4, so only need firmly discharging rubber 5 be extracted when will change separately discharging rubber 5.And punch 4 and punch retainer 3 are linked together by interference fits, punch 4 is independently parts, can take out change from punch retainer 3.As depicted in figs. 1 and 2, die 6 little above large below, and pressing plate 7 large above below under, pressing plate 7 and die 6 form trapezoidal cooperation, bolt 11 also makes pressing plate 7 pairs of dies 6 cause horizontal extruding while being fixed on die shoe 8 by pressing plate 7, be fixed on by die 6 on die shoe 8; Therefore, only need unclamp bolt 11 just can take out and change die 6.
In sum, although punch retainer 3, punch 4, discharging rubber 5 and die 6 in movable mold are different in the mode changed, be all easier to change.And die shank 1, upper mould fixed plate 2, pressing plate 7 and die shoe 8 in mould bases directly do not affect due to the shape with motor stamping, so when producing difform motor stamping, mould bases does not need to change, can be general.Thus cost saving, do not need to spend human and material resources and time again making on mould bases.
Obviously, under the prerequisite not departing from principle of the present invention, the some improvement made or modification all should be considered as protection scope of the present invention.
