A kind of surrounding surrounds structure Bending Mould
The present invention relates to pressing and bending technical field of mold, and in particular to a kind of surrounding surrounds structure Bending Mould.
With the continuous improvement of industrial product quality, compared with machining and other methods of plastic working, punching press adds
Work all has the advantages of many unique in technical elements or economic aspect.It is mainly shown as：1, the production of punch process
Efficiency high, and it is easy to operate, it is easy to accomplish mechanization and automation.2, because mould ensure that the size and shape of punching press during punching press
Shape precision, and the general surface quality for not destroying stamping parts.3, punching press can process that size range is larger, and complex-shaped zero
Part.But mould used in punch process typically has specificity, sometimes one complex parts need several molds to add
Work is molded, and the precision of Making mold is high, and technical requirements are high, are technology-intensive products.
Surrounding surrounds infrastructure product shaping, because in the particularity of molding structure, in process, support can not be found
Stress point, so easily being flattened by mould, also easily cause the precision of bending can not meet technological requirement, so as to cause product by
Damage, its outward appearance is influenceed, it is necessary to the later stage does shaping, manufacturing procedure is added, can seriously cause product rejection, even resulting in subsequently makes
Equipment is damaged in.
Therefore, in view of the above-mentioned problems, the present invention proposes a kind of new technical scheme.
The content of the invention
It is simple to operate it is an object of the invention to provide a kind of rational in infrastructure, in process, uniform force, ensure plus
The surrounding of the precision of work and the quality of product surrounds structure Bending Mould.
The present invention is achieved through the following technical solutions：
A kind of surrounding surrounds structure Bending Mould, including upper die and lower die, the upper mould are connected with turn from top to bottom
Die holder, upper padding plate, train wheel bridge, cope plate and upper de- plate, the lower mould are connected with bottom plate, lower piece, lower mould in turn from bottom to top
Seat, lower bolster, lower plate and lower template, the first spring is installed on the upper bolster, first lower spring end, which is connected with, to be beaten
Convex punching, the raising rush both sides and are mounted on bending punching, and the bending punching is fixedly mounted on upper padding plate, solid on the train wheel bridge
Dingan County is equipped with slotting tool, and the lower template side is fixedly mounted fixed block, second spring, the second spring are set on the fixed block
It is connected with the sliding block of fixed block side, the slotting tool is engaged with sliding block.
Further, the lower template enters block provided with lower mould, and the lower mould enters block and is provided with the 3rd spring, and the described 3rd
Jigger pin is installed, the jigger pin is engaged with raising punching on spring.
Further, the bending rushes both sides and is provided with limited block, and the limited block is fixedly mounted on de- plate.
Further, the upper de- plate is provided with the locating piece being engaged with bending punching.
Further, the handle that the sliding block side is set, the handle enter the notch on block with lower mould and are engaged.
Further, contour sleeve, the contour sleeve and the groove in lower template are installed on the upper padding plate side
It is engaged.
The beneficial effects of the invention are as follows：This mould structure is reasonable, simple to operate, by the mutual cooperation of sliding block and slotting tool,
Ensure uniform force in the product processing of surrounding encirclement structure, avoid the damage in process or even scrap, so as to
Reduce the operational sequence of correlation, reduce production cost, improve operating efficiency, meanwhile, avoid the mould in process
Tool damage, improves the mold use life-span, moreover, by being accurately positioned, ensure that the crudy of product.

Illustrate to be described further the present invention below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of surrounding surrounds structure Bending Mould, including upper die and lower die, upper mould connect successively from top to bottom
Be connected to upper bolster 1, upper padding plate 2, train wheel bridge 3, cope plate 4 and upper de- plate 5, lower mould be connected with turn from bottom to top bottom plate 6, under
Block 7, die shoe 8, lower bolster 9, lower plate 10 and lower template 11,1 is provided with the first spring 12 on upper bolster, under the first spring 12
End is connected with raising punching 13, and raising rushes 13 both sides and is mounted on bending punching 14, and bending punching 14 is fixedly mounted on upper padding plate 2, on
Slotting tool 17 is installed with clamping plate 3, the side of lower template 11 is fixedly mounted fixed block 18, second spring 19 is set on fixed block 18,
Second spring 19 is connected with the sliding block 20 of the side of fixed block 18, and slotting tool 17 is engaged with sliding block 20.
In the present embodiment, lower template 11 enters block 22 provided with lower mould, and lower mould enters block 22 and is provided with the 3rd spring 23, and the 3rd
Jigger pin 24 is installed, jigger pin 24 is engaged with raising punching 13 on spring 23.
In the present embodiment, bending rushes 14 both sides and is provided with limited block 16, and limited block 16 is fixedly mounted on de- plate 5.
In the present embodiment, upper de- plate 5 is provided with the locating piece 15 being engaged with bending punching 14.
In the present embodiment, the handle 21 that the side of sliding block 20 is set, the notch 25 that handle 21 enters with lower mould on block 22 are engaged.
In the present embodiment, contour sleeve 26 is installed on the side of upper padding plate 2, contour sleeve 26 with it is recessed in lower template 8
Groove 27 is engaged.
During this mold work, upper mould pushes, and slotting tool pushes sliding block, and with the height pushed, the downward mould of sliding block enters
Slided at block, until upper mould pushes completely, the handle of sliding block side enters the notch on block with lower mould and fitted, and forms a stress
Face, guarantee rush convex punching and bending and rush work, make uniform force in product processing, will not because of in the course of work because can not
Find stress point and produce impaired, after machining, upper mould is risen, and slotting tool is walked upwards with upper mould, and sliding block passes through the second bullet
The effect of spring, returns to start bit.
This mould structure is reasonable, simple to operate, by the mutual cooperation of sliding block and slotting tool, ensures that surrounding surrounds the production of structure
Uniform force in product process, avoid the damage in process or even scrap, so as to reduce the operational sequence of correlation,
Production cost is reduced, improves operating efficiency, meanwhile, the burn failure in process is avoided, improves making for mould
With the life-span, moreover, by being accurately positioned, the crudy of product ensure that.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
