Spring type it is very much, it is domestic mainly based on " ω " type and " e " type spring.Wherein, " e " type spring has many kinds, such as
III type spring, DI spring, PR spring etc., overwhelming majority enterprises are that the spring of each model is intended to design and a set of shapes three times at present
Mold, every mold also need to carry out vulnerable part deposit, and mold occupied fund is big when enterprise's spring kind is more, difficult management.
" e " type spring mold at this stage, there are following deficiencies:
1, every kind of model spring is both needed to one set of die, and when spring kind is more, mold occupied fund is big；
2, every kind of model spring is both needed to one set of die, and replacing spring kind every time, time-consuming；
3, every kind of model spring is both needed to prepare vulnerable part, brings difficulty to management.
Summary of the invention
The present invention provides a kind of e spring press-bending flattening mold, realizes that one set of die processes a variety of springs.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of e spring, which is bent, flattens mold, including upper die component and lower mold assemblies, the upper die component include cope plate with
And the horizontal flattening upper mold for being sequentially arranged in cope plate bottom surface, middle limb upper mold and bend upper mold, and by upper mold side fixed plate and
Upper mold side compression block is fixed；The lower mold assemblies include that bottom plate, the framework being arranged on bottom plate and level are sequentially arranged
In the intracorporal flattening lower die of frame, middle limb lower die and lower die is bent, and is fixed by side plate；The cope plate is provided with positioning
Square taper pin, height forming block is provided in the framework, and positioning side taper pin and height shape block and be used to position spring.
The side of the cope plate be additionally provided with for side positioning flatten upper mold and middle limb upper mold upper mold tail locating piece, in
Limb tail locating piece, and the push plate for compressing upper mold tail locating piece, middle limb tail locating piece.
Anti-receding device forming blocks are placed in the press-bending lower die inside groove, bending lower die arranged beneath has adjustment cushion block, should
Anti-receding device forming blocks pass through the through-hole for being provided with press-bending lower die inside groove lower end and contact with cushion block is adjusted.
By carrying out molding limit to module between the cope plate and framework.
From the above technical scheme, the present invention can make die ontology unified, and every kind of spring is only each by adjusting mold
The cushion block of component realizes that one set of die processes a variety of springs, and one set of die, pole can also be used only by producing a variety of springs even if enterprise
The occupancy of big reduction Mould Enterprise fund.

Specific embodiment
A kind of preferred embodiment of the invention is described in detail with reference to the accompanying drawing.
As shown in Figures 1 to 4, it includes upper die component 100 and lower mold assemblies 200, upper mold group that the e spring, which bends and flattens mold,
Part can move in vertical direction a certain range, realize spring forming, by carrying out to module 300 between cope plate and framework
Molding limits, and between each component of upper die and lower die component, the adjustment of size is realized by the Gaskets processed in advance, with
Meet different types of spring processing.
The upper die component 100 includes cope plate 101 and the horizontal flattening upper mold for being sequentially arranged in cope plate bottom surface
102, middle limb upper mold 103 and press-bending upper mold 104, and be fixed by upper mold side fixed plate 105 and upper mold side compression block 106.
The side of cope plate is additionally provided with upper mold tail locating piece 108, the positioning of middle limb tail that upper mold and middle limb upper mold are flattened for side positioning
Block 109, and the push plate 110 for compressing upper mold tail locating piece, middle limb tail locating piece.
The lower mold assemblies 200 include that bottom plate 201, the framework 202 being arranged on bottom plate and level are sequentially arranged in frame
Intracorporal flattening lower die 203, middle limb lower die 204 and press-bending lower die 205, and be fixed by side plate 206.The press-bending lower die
Anti-receding device forming blocks 208 are placed in inside groove, bending lower die arranged beneath has adjustment cushion block 209, the anti-receding device forming blocks
It is contacted by being provided with the through-hole for bending lower die inside groove lower end with cushion block is adjusted.
101 lower end of cope plate is additionally provided with positioning side's taper pin 107, and height forming block is provided in the framework 202
207, positioning side's taper pin and height forming block are for positioning spring.
When production, the spring blank of red heat be placed on bend lower die 205, flatten lower die 203 on, and rely in limb lower die 204,
Positioning side's taper pin 107, height forming block 207 realize the positioning of spring blank, and then upper die component is moved downward to spring forming, on
Membrane module retracts to original position.
When replacing spring kind, upper mold side compression block 106, push plate 110, side plate 206 are first unclamped, by bending lower die
205, lower die 203 is flattened, upper mold 102, the bottom for bending upper mold 104 and side is flattened and increases Gaskets to required size, so
Upper mold side compression block, push plate, side plate are locked afterwards, are both adjusted and are finished.
Embodiment described above is only that preferred embodiments of the present invention will be described, not to model of the invention
