Abstract
The utility model discloses a friction plate fine blanking trimming die with a reshaping function, which is divided into an upper die part and a lower die part; the connection mode of each part of the lower die part is same as that of a conventional fine blanking trimming die; the upper die part is provided with an elastic cushion block between a terrace die fixed base plate and a knock out plate; and the elastic cushion block is pushed through push rods. The original knock out pin is cancelled to return materials, and an elastic glue cushion is additionally arranged and acts on a material returner through four push rods. Due to the existence of the elastic glue cushion, in the process that the fine blanking upper die part moves down, the material returner is in contact with a core plate firstly, the prepressure of the elastic glue cushion acts on the core plate through the push rods and the material returner to take the reshaping action on the plane buckling deformation of the core plate. The utility model simultaneously carries out reshaping and blanking, and thereby, manufacturing procedures are reduced, process rejects generated by independent reshaping due to dimensional change overproof are avoided and the processing efficiency and the product quality are improved. The friction plate fine blanking trimming die can be modified on the traditional mould and is simple and convenient and is easy to use.
Description
Technical field
The utility model relates to a kind of machine die, and particularly a kind of essence that is used for aluminium alloy friction plate central layer is washed into the pattern tool.
Background technology
Existing friction plate central layer is after being shaped to material by aluminium alloy compression casting, dashes processing through essence and removes the unnecessary blank of periphery, obtains the finished product of required appearance and size.Because press casting procedure SMIS intralamellar part produces unbalanced internal stress, cause central layer to eject the back and produce buckling deformation.Existing fine blanking die (as Fig. 1) employing activity stripping attachment, use and play bar (shown in the inner branch of dotted line circle among Fig. 1) material returned, essence is broken through in the journey can only excise periphery material, can't eliminate buckling deformation, therefore need eliminate buckling deformation with subsequent handling, irregular variation takes place in the central layer appearance and size after essence is dashed, and causes product qualified rate to reduce, and the reduction of the manufacturing cost of corresponding friction plate is difficult more therewith.
The utility model content
The utility model has overcome the deficiencies in the prior art, provides a kind of friction limit essence towards edger, and this mould has shaping feature, has solved problems of the prior art.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of friction plate essence with shaping feature is towards edger, be divided into part of the upper die and part of the lower die, the part of the lower die comprises lower bolster, punch-die fixed head, punch-die, stripper, locating piece, moves back part device, die and backing plate one, guide finger, packing ring, guide pin bushing and guide pillar, spring, and the connected mode of each parts of part of the lower die is with conventional smart the same towards the edger connected mode; The part of the upper die comprises punch, punch retainer, cope match-plate pattern, cushion block one, backing plate two, push rod, re-packs, die shank, cushion block two, wherein, it below the cope match-plate pattern punch retainer, punch is fixedly mounted on the punch retainer below, is fixedly backing plate of punch above the cope match-plate pattern, and cope match-plate pattern and punch fixedly backing plate have cushion block one, push rod connects backing plate one and re-packs, punch fixedly backing plate top is a die shank, punch fixedly backing plate and re-pack between be provided with elastic cushion block, this elastic cushion block promotes by push rod.
Further technical scheme is:
The area of described elastic cushion block is close with the area size that re-packs.
Described spring is installed in the guide pin hole, is used for detecting.
Push rod has four.
Compared with prior art, the beneficial effects of the utility model are: the central layer essence of described band shaping feature is towards edger, cancel the original bar material returned of beating, increase by an elastic rubber fitting and act on the stripping attachment by 4 push rods, elastic rubber fitting is in its pre-compressed state when mounted.Because the existence of elastic rubber fitting, when essence rushes in the folding process of mould part, stripping attachment is the contact central layer earlier, the precompression of elastic rubber fitting is by push rod, and stripping attachment acts on the central layer, and shaping operation is played in the plane warping distortion of central layer, meanwhile, die, punch are finished the edge-cutting and hole-punching action.The direct benefit of bringing is: one, shaping and stamping-out carry out simultaneously, have reduced manufacturing procedure, have avoided the operation waste product of independent shaping because of the overproof generation of change in size, have improved working (machining) efficiency and product quality.Two, can on existing mold, transform, simple and easy to do.
