At present, exempt from the smoothing operation that flatness is not set in the making mould of weldering contact pin, make the product upper and lower surface out-of-flatness processed, and product plane degree is poor, affects the electric property of product, by analyzing the smoothing operation increasing flatness, after adopting new technique, the upper and lower surface of product is smooth, good with the contact of object part, meet the high-precision requirement of product design, need to research and develop mould that is a kind of and smoothing operation adaptation for this reason.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and provides a kind of leveling die exempting to weld contact pin flatness, and the flatness of exempting to weld contact pin can control in 0.04mm by it, substantially increases Product Precision, meets the functional requirement of product.
The purpose of this utility model is achieved in that a kind of leveling die exempting to weld contact pin flatness, comprises upper die and lower die; Described patrix comprises the upper bolster, upper padding plate, cope match-plate pattern, discharging backing plate and the stripper that connect successively from top to bottom; Counterdie comprises the die shoe, lower bolster and the lower bolster that connect successively from bottom to top; Wherein, described cope match-plate pattern is arranged two upper plenums, in each upper plenum, fix a smoothing drift respectively; The bottom working face of each smoothing drift all does mirror finish process; The upper plenum of the corresponding described cope match-plate pattern in inside of described discharging backing plate is provided with two perforation for interspersed described smoothing drift; In described stripper, the upper plenum of corresponding described cope match-plate pattern arranges two for smoothing the cavity of drift described in correcting; Arrange two in described lower bolster and descend cavity one to one with described smoothing drift, fix one respectively in each lower cavity and smooth into block; Each upper end working face of smoothing into block all does mirror finish process;
It is 0.04 ~ 0.06mm to described surperficial overvoltage shaping amount of exempting to weld contact pin jointly that described patrix smoothing drift coordinates counterdie to smooth into block.
Above-mentioned exempts from the leveling die welding contact pin flatness, and wherein, the upper surface of each described smoothing drift also arranges respectively on one and regulates cushion block.
Above-mentioned exempts from the leveling die welding contact pin flatness, wherein, regulates cushion block under each described bottom face of smoothing block also arranges one respectively.
Above-mentioned exempts from the leveling die welding contact pin flatness, and wherein, described smoothing drift and the material of smoothing into block are wolfram steel.
Leveling die of exempting from weldering contact pin flatness of the present utility model, adopt the smoothing drift of patrix to coordinate the smoothing of counterdie to enter block and jointly overvoltage shaping is carried out to the surface of product, eliminate the internal stress of material self to greatest extent, can the flatness of exempting to weld contact pin be controlled in 0.04mm, substantially increase Product Precision, meet the functional requirement of product.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
First refer to Fig. 2 a and Fig. 2 b, leveling die of exempting from weldering contact pin flatness of the present utility model, comprises patrix 1 and counterdie 2.Patrix 1 comprises the upper bolster 4, upper padding plate 5, cope match-plate pattern 6, discharging backing plate 7 and the stripper 8 that connect successively from top to bottom; Counterdie 2 comprises the die shoe 11, lower bolster 10 and the lower bolster 9 that connect successively from bottom to top; Wherein:
Cope match-plate pattern 6 is arranged two upper plenums, in each upper plenum, fix a smoothing drift 22 respectively; The material of smoothing drift 22 is wolfram steel; The shape of the bottom working face of these two smoothing drifts 22 respectively with the front shape of product 3 and rear shape adaptive and all do mirror finish process; The upper surface of each smoothing drift 22 also arranges a upper adjustment cushion block 21 respectively;
The upper plenum of the corresponding cope match-plate pattern 6 in inside of discharging backing plate 7 is provided with two perforation for interspersed smoothing drift 22;
In stripper 8, the upper plenum of corresponding cope match-plate pattern 6 arranges two cavitys for correcting smoothing drift 22;
Arrange two in lower bolster 9 and descend cavity one to one with described smoothing drift, fix one in each lower cavity respectively and smooth into block 23; The material of smoothing into block 23 is wolfram steel; Each upper end working face of smoothing into block 23 all does mirror finish process; Cushion block 24 is regulated under each bottom face of smoothing block 23 also arranges one respectively.
The smoothing drift 22 cooperation smoothing be arranged in lower bolster 9 be arranged in cope match-plate pattern 5 enters block 23 and carries out overvoltage shaping processing to the surface of product (exempting to weld contact pin) 3 simultaneously.Smoothing drift 22 coordinates the surperficial overvoltage shaping amount to exempting to weld contact pin to be 0.04 ~ 0.06mm into block 23 with smoothing, and eliminates the internal stress of material self to greatest extent, thus obtains high-precision planarity requirements, meet the functional requirement of product.
Leveling die of exempting to weld contact pin flatness of the present utility model is when mold closing, product 3 is placed on the upper surface of smoothing block 23, patrix 1 vertically moves downward under the effect of punch press power, be arranged on smoothing drift 22 in cope match-plate pattern 6 and the smoothing be arranged in lower bolster 9 to enter block 23 and carry out overvoltage shaping processing to product 3 surface simultaneously, smoothing action completes.
Leveling die of exempting to weld contact pin flatness of the present utility model is when die sinking, under the effect of punch press reset Hui Li, patrix 1 is vertically moved upward, the upper surface of product 3 thrown off by the smoothing drift 22 be arranged in cope match-plate pattern 6, meanwhile, under the active force of the float lifting mechanism of mould inside, product 3 moves upward, throw off and smooth into block 23, complete die sinking process.
Smooth the thickness of the upper adjustment cushion block 21 that drift 22 top is arranged by adjustment and smooth the thickness of the lower adjustment cushion block 24 arranged bottom block 23, trace adjustment can be realized, to adapt to the fluctuation of product thickness to the impact of product plane degree to the amount of over-pressurization of product.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
