Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
The utility model provides a kind of one-time formed mould of negative angle bending, and as depicted in figs. 1 and 2, it includes
Mold forming mechanism 1, lower mold forming mechanism 2, binder block 3, spring mechanism 4, Mobile base 5, binder block 3 are set by spring mechanism 4
On Mobile base 5, lower mold forming mechanism 2 is arranged on Mobile base 5 and positioned at the side of binder block 3,1, upper die forming mechanism
Above binder block 3;Under the limitation of the lower and upper mold forming mechanism 1 of promotion of Mobile base 5, binder block 3 by spring mechanism 4 to
Lower movement, lower mold forming mechanism 2 move up, and pass through displacement difference completion pair caused by the binder block 3 and lower mold forming mechanism 2
The converted products 6 being placed on lower mold forming mechanism 2 and binder block 3 is once bent into negative angle, is so greatly reduced
Operating procedure, manpower is saved, reduce the cost of production, improve processing efficiency.
Further, upper die forming mechanism 1 includes upper die forming block 11, Bending Slide Block 12, fixed seat 13, upper die forming block
11 are fixedly connected with Bending Slide Block 12, and chute 131 is provided with fixed seat 13, and Bending Slide Block 12 is connected logical with chute 131
Cross and upper die forming block 11 is arranged to the structure that can slide, after the completion of operation, be easy to take out the product of machined completion;As
It is preferred that upper die forming block 11 elects Bending punch as.
Further, lower mold forming mechanism 2 includes lower mold forming block 21, roller bearing folded block 22, material pushing needle 23, fixed block
24, the semicircular in shape of roller bearing folded block 22, the groove 211 to match with roller bearing folded block 22 is provided with lower mold forming block 21, roll
