Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of backboard flanging mould obliquely, comprise module 1 and correspondence and be arranged at lower module 2 below described upper module 1, wherein, described upper module 1 comprises upper bolster 14 and train wheel bridge 12 from top to bottom, and be fixedly connected with, be provided with the spacing fixing upper liner plate 11 of described train wheel bridge 12 below described upper bolster 14, the working face of described train wheel bridge 12 is provided with the first skew wall 121; Described lower module 2 comprises die shoe 25, described die shoe 25 is fixedly installed lower bolster 23 and lower plate 22, and by the spacing fixing lower liner plate 21 of described lower plate 22, the working face of described lower plate 22 is provided with the second skew wall 221 matched with described first skew wall 121; Elastic positioning device 4 is provided with between described upper module 1 and lower module 2.
Described elastic positioning device 4 comprises alignment pin 41 and corresponding locating hole 43, described locating hole 43 is arranged at the bottom of described upper liner plate 11, described alignment pin 41 is through described lower liner plate 21, described alignment pin 41 bottom surface is provided with support spring 42, conflict described die shoe 25 in the bottom surface of described support spring 42, the bottom of described alignment pin 41 up extrudes described lower liner plate 21; Buffer spring 44 is provided with bottom described locating hole 43; Be provided with stage clip 3 between described upper liner plate 11 and upper bolster 14, between described lower liner plate 21 and die shoe 25, be provided with stage clip 3, increase the cushioning effect in the course of work and punching press stability.
Under the natural extended configuration of described buffer spring 44, the length between its bottom to described locating hole 43 outer face is that described alignment pin 41 stretches out 1/2 ~ 2/3 of face length, shrinks generation elastic force when enabling described alignment pin 41 insert described locating hole 43.
Offer a groove 122 below described first skew wall 121, increase the elasticity of described first skew wall 121, reduce the effect of being hit in the course of work and stress is concentrated, cause damage.
The top of described upper bolster 14 is provided with cushion block 15, and the top of described upper cushion block 15 is provided with mounting plate 16; The below of described die shoe 25 is provided with lower cushion block 26, and the below of described lower cushion block 26 is provided with bottom plate 27, easy disassembly, more mold exchange.
Be provided with upper padding plate 13 between described upper bolster 14 and train wheel bridge 12, between described die shoe 25 and lower bolster 23, be provided with lower bolster 24, prevent upper bolster 14 described in impulsive force macrolesion and die shoe 25.
In use, when upper module 1 down moves, alignment pin 41 inserts locating hole 43, upper module 1 continues down to move, upper surface and buffer spring 44 bottom of alignment pin 41 contact, and buffer spring 44 and support spring 42 all shrink and produce elastic force, for the motion of upper liner plate 11 brings double buffering.And, support spring 42 shrinks and the power of liner plate 21 under alignment pin 41 bottom squeeze is reduced gradually, namely the support force of support spring 42 to lower liner plate 21 reduces gradually, liner plate 21 under stage clip 3 under described lower liner plate 21 and support spring 42 common support, when support spring 42 reduces gradually to lower liner plate 21 support force, stage clip 3 pressure under described lower liner plate 21 becomes large gradually and shrinks generation elastic force, for bringing buffering when upper liner plate 11 contacts lower liner plate 21.It is faster that upper module 1 moves downward speed, and the cushioning effect that the stage clip 3 under described lower liner plate 21 brings to upper liner plate 11 is more remarkable.Before upper liner plate 11 contacts lower liner plate 21, for buffer spring 44, support spring 42 coordinate the double cushioning effect of generation; When upper liner plate 11 contacts lower liner plate 21, the cooperation of buffer spring 44, support spring 42, stage clip 3 produces triple buffer effect, and support spring 42 has a progressive formation to lower liner plate 21 support force, punching press stability greatly improves, improve yield rate, and reduce grinding tool wearing and tearing, increase the service life.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
