Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figures 1 to 6, a kind of metal plate product centering block bending construction, including centering block 6 and the centering block for being installed on the both ends of centering block 6 Fixed seat 7, the mounting groove for installing centering block 6, the mounting groove of two centering block fixed seats 7 are provided with the centering block fixed seat 7 It is oppositely arranged, the both ends of the centering block 6 are respectively arranged with boss, and the both ends of the centering block 6 are supported on by the way that boss is swingable In mounting groove.
Locating part is additionally provided with around the centering block 6 to be carried out to hunting range of the centering block in the mounting groove It is spacing.The locating part includes the wearing plate 4 that the top of the centering block 6 is installed, and when swinging, the top of the centering block 6 can be along institute Wearing plate 4 is stated to slide.
The wearing plate 4 prevents because the abrasion of train wheel bridge 3 is so as to causing bending angle not caused by the rotation of centering block 6 Enough, the wearing plate 4 can be replaced according to the degree of wear, reduce the production loss of whole device, and extend machine uses the longevity Life.
The locating part also includes the punch-pin block 5 being vertically arranged in mounting groove, and when swinging, the centering block 6 can be along installation Groove bottom land is swung, and the amplitude of swing is limited to the distance between punch-pin block 5 and mounting groove side.When centering block 6 is swung, both protected The abundant swing of centering block 6 has been demonstrate,proved, while in turn ensure that the degree of accuracy that centering block 6 is swung, to ensure the punching press of stamping parts product 13 essence Degree.
The locating part also includes the centering block guide pad 18 located at the side of centering block 6, and when swinging, the side of the centering block 6 can Along the side walls of the centering block guide pad 18.The centering block guide pad 18 causes the swing process steady and smooth of centering block 6, ensures The accuracy of bending.The centering block guide pad 18 is located at the lower section of wearing plate 4.
The boss has the first confined planes and the second confined planes close to oscillation center, first confined planes and second It is θ to have angle between confined planes1Angle, the mounting groove have close to oscillation center groove bottom and side, the groove Angle between bottom surface and side is θ2, wherein θ21.The structure that boss and mounting groove are engaged reduces prior art construction In centering block chosen axis, save the artificial of material, processing and assembling, shorten the manufacturing cycle of mould, reduce mould Manufacturing cost.
The top of the centering block 6 is also fixedly connected with the compression reaction device being adapted with centering block 6, and the compression and back reassembles Put including ejector pin, spring and only symbol screw, the only symbol screw are fixed on upper bolster 1, the lower end of the only symbol screw and bullet Spring is fixedly connected, and the lower end of the spring is connected with ejector pin, and the lower end of the ejector pin is connected to the top of centering block 6.
As is seen in figs 7-10, the invention also discloses a kind of metal plate product mold, including upper die and lower die and metal plate product pendulum Block bending constructs, and the upper mould includes passing sequentially through upper bolster 1, upper padding plate 2, train wheel bridge 3 that screw is fixedly connected from top to bottom, The size of the upper bolster 1 is more than the length of train wheel bridge 3 and upper padding plate 2, and the train wheel bridge 3 is identical with the size of upper padding plate 2.
The centering block fixed seat 7 of the metal plate product centering block bending construction is arranged on the lower surface of train wheel bridge 3 in opposite directions;It is described The lower end of punch-pin block 5 is fixed in mounting groove, and the upper end of punch-pin block 5 is fixed in train wheel bridge.The wearing plate 4 is embedded in The inside of train wheel bridge 3, and the lower plane of wearing plate 4 is concordant with the lower plane of train wheel bridge 3.
The stripper apparatus for the demoulding is also associated with the upper mould, the stripper apparatus includes stripper plate 9, stripper pad 8 and upper mould spring 17, the top of the stripper plate 9 be connected with stripper pad 8, mould be fixedly connected with the stripper pad 8 Spring 17, the upper end of the upper mould spring 17 are fixed in upper bolster 1.The length and width of the stripper plate 9 is respectively less than de- material The length and width of backboard 8, and the shape adaptation on the top of the shape of the left and right sides of stripper plate 9 and centering block 6.
The lower mould includes bending female die 10, lower bolster 12, die shoe 14, the and of lower cushion block 15 being sequentially connected from top to bottom Bottom plate 16, the shape of the bending female die 10 are adapted with the shape of centering block.
Cavity plate block 11 is additionally provided between the bending female die 10 and lower bolster 12, the bottom of cavity plate block 11 is fixed In lower bolster 12, its top is fixed on inside bending female die 10.The length and width of the lower bolster 12 is respectively smaller than bending The length and width of cavity plate 10, the die shoe 14, lower bolster 15, the size of bottom plate 16 are identical, and length and width is big In the length and width of bending female die 10.
When it is implemented, as shown in figure 1, metal plate product mold is fixed on forcing press first, part of the upper die is fixed on The upper table face of forcing press, part of the lower die are fixed on the lower table face of forcing press, stamping parts product 13 then are put into folding On curved cavity plate 10.
As shown in figure 8, the upper table face of forcing press is descending, part of the upper die is descending therewith, stripper plate 9 first with stamping parts Product 13 contacts, and upper mould spring 17 starts to compress, and stripper plate 9 starts binder, now centering block 6 and compression reaction device thereon In free state.
As shown in figure 9, forcing press continues traveling downwardly, upper mould continues traveling downwardly therewith, the contact product of centering block 6, now stripper plate 9 Stamping parts product 13 is pushed down to keep it from moving.Under the descending power effect of forcing press, circle where R angles of the centering block 6 on its boss The heart rotates, and profile of its rotational trajectory just with the required shaping of stamping parts product 13 matches.Produced when centering block 6 rotates bending Active force promote that compression reaction device thereon is up, i.e., ejector pin is up, and up the making every effort to promote of ejector pin makes in compression reaction device Spring gradually reduce.
Then upper mould is continued traveling downwardly, until mould closes completely, centering block 6 completes bending, and now upper mould spring 17 is pressed completely Contract, the spring in compression reaction device is also compressed completely, and stamping parts product 13 is buckled on bending female die 10 completely.
As shown in Figure 10, forcing press is up, and upper mould is with up, mold open, in the presence of the power of upper mould spring 17 Stripper plate 9 is gradually up, pushes movable pendulum block 6 and starts to start to rotate around the center of circle where R angles thereon caused by stripper plate 9 is up, Direction of rotation is in opposite direction when being just molded with mould matched moulds stamping parts.The rotation of centering block 6 promotes compression reaction device simultaneously, then presses The spring of retraction apparatus for coating is gradually resetted by complete compressive state, and centering block 6 departs from shaped article while spring resets completely.This When can be taken off the stamping parts product 13 of final molding.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's Principle, and limiting the scope of the invention can not be construed in any way.Based on explanation herein, the technology of this area Personnel would not require any inventive effort the other embodiments that can associate the present invention, and these modes are fallen within Within protection scope of the present invention.
