Technical field
The present invention relates to a kind of mould, especially a kind of connection sheet step-feeding stamping modular mold.
Background technology
Connection sheet is one of main components in cable testing bridge, the connection between crane span structure main body.The traditional mode of production mode connecting sheet is: after going out special section bar with belt steel rolling, cuts off through particular manufacturing craft and pressing equipment, then realizes through twice punching.This mode of production, its manufacturing process is many and complicated, for the connection sheet of different size, needs to open the mould matched.Change production specification is it is necessary to change corresponding mould, and quantifying production needs to take substantial amounts of equipment and human resources, and not only investment is big, work efficiency is slow, and cost is high, here it is the weak point existing for prior art.
Summary of the invention
The technical problem to be solved in the present invention, it is simply that for the deficiency existing for prior art, and providing a kind of integrated-type, punching, bending and cut off in the connection sheet step-feeding stamping modular mold of one, its compact conformation, work efficiency is high.
This programme is achieved by the following technical measures: this connection sheet step-feeding stamping modular mold includes part of the upper die, part of the lower die and guiding mechanism, described part of the upper die includes upper mold frame plate and is arranged on the molding concave die below upper mold frame plate and stripper plate, is disposed with drift, bending upper die and shearing upper slitter between described stripper plate and upper mold frame plate；Described part of the lower die includes lower mold frame plate and is arranged on cutter under the forming convax mould above lower mold frame plate, punching lower mold, bending lower die and shearing；The lower end of described drift, bending upper die and shearing upper slitter sets gradually through the vertical dimension between stripper plate, and molding concave die, drift, bending upper die and the bottom of shearing upper slitter and upper mold frame plate lower surface is ascending.
Be fixedly connected sequentially on the lower surface of above-mentioned upper mold frame plate upper die plate and upper mould fixed plate from top to bottom, and described molding concave die, drift, bending upper die and shearing upper slitter are fixing with upper mould fixed plate respectively to be connected.Upper die plate is through Overheating Treatment and processing, and its intensity is higher than upper mold frame plate, is used for padding drift, red needle, prevents drift afterbody top to hinder upper mold frame plate, and meanwhile, it can also adjust the height of mould.In operation process, bear the counteracting force of cutter under forming convax mould, punching lower mold, bending lower die and shearing by upper die plate, to protect upper mold frame plate, extend the service life of upper mold frame plate.
It is additionally provided with inner guiding post between above-mentioned upper mould fixed plate and stripper plate, stripper plate is stretched out in the lower end of described inner guiding post, it is provided with, in described punching lower mold, the pilot hole coordinated with inner guiding post, inner guiding post coordinates with pilot hole, improve the guiding accuracy of mould inner punch, shears, it is also prevented from stripper plate dislocation and interferes with drift, to avoid drift to fracture.
Contour adjusting screw rod it is provided with between above-mentioned upper mould fixed plate and stripper plate, contour adjusting screw rod can ensure that upper mold frame plate, upper die plate and upper mould fixed plate are in level all the time, to ensure part of the upper die beading molding, punching, bending and to cut off the quality of operation.
Being provided with elastomer between above-mentioned upper mould fixed plate and stripper plate, this elastomer is prone to the de-material of stripper plate.In order to reach the most de-material effect, above-mentioned elastomer is excellent power glue cylinder, excellent power offset plate, Flat wire spring or nitrogen spring, it is preferred to use excellent power glue cylinder or excellent power offset plate, so that the strength of elastomer compares equilibrium.
Shearing upper slitter is stretched out in the end of above-mentioned stripper plate, while this structure can ensure that connector can be carried out compressing location by stripper plate, also has the function playing material, is kicked off by the connector machined in time.
Above-mentioned guiding mechanism includes guide pin bushing and the guide pillar coordinated with guide pin bushing, and described guide pin bushing is fixing with upper mold frame plate to be connected, and described guide pillar is fixing with lower mold frame plate to be connected.Coordinated with guide pin bushing by guide pillar, the whole part of the upper die in motion is guided, it is ensured that the stationarity of part of the upper die motion, guide and to control part of the upper die involutory with tram with part of the lower die.
Above-mentioned guide pillar is ball guide pillar.
The lower end of above-mentioned lower mold frame plate is fixedly connected with equal height cushion block, equal height cushion block can improve the whole height of mould, to check the blanking situation of punching, simultaneously, it is also used as the cleaning passage of punched scrap, be conducive to the diffusion of mould punching force, the most as required, strengthen the ability to bear of mould local.
The beneficial effect of this programme can be learnt according to the narration of such scheme, in this connection sheet step-feeding stamping modular mold, described part of the upper die includes upper mold frame plate and is arranged on the molding concave die below upper mold frame plate and stripper plate, is disposed with drift, bending upper die and shearing upper slitter between described stripper plate and upper mold frame plate；Described part of the lower die includes lower mold frame plate and is arranged on cutter under the forming convax mould above lower mold frame plate, punching lower mold, bending lower die and shearing；The lower end of described drift, bending upper die and shearing upper slitter sets gradually through the vertical dimension between stripper plate, and molding concave die, drift, bending upper die and the bottom of shearing upper slitter and upper mold frame plate lower surface is ascending.After using this structure, the belt steel material of same width is placed between part of the upper die and part of the lower die, in the one stroke (i.e. the one stroke of part of the upper die) of forcing press, can complete to connect the pressure reinforcement of sheet, rush connecting hole, 90 ° of bendings and shear the punching of four procedures, owing to above-mentioned operation is to carry out on different stations in the one stroke of forcing press, continuous prodution can be realized, both production efficiency can be significantly increased, production cost can be reduced again, and the percent defective of processing is low.As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and significantly progress, and its beneficial effect implemented also is apparent from.
