Description

The continuous production mould of little back splint

Technical field

The utility model belongs to composite die apparatus field, particularly relates to the continuous production mould of a kind of little back splint.

Background technology

At present, satellite antenna comprises antenna and bearing, and antenna is connected with bearing by column, while installing due to antenna, need to regulate the elevation angle, antenna is to be connected with column with little back splint combination by large back splint, after large back splint and the combination of little back splint, can regulate the elevation angle, to meet the needs that antenna is fixed and aerial angle regulates, but the little back splint production mould of prior art comprises ten secondary moulds, the corresponding stamping machine of every secondary mould, and every stamping machine needs workman's operation, during production, first by banded iron plate stamping-out out, subsequently successively by nine other stamping machines ability final molding, also need workman between every stamping machine, to carry semi-finished product, therefore exist the production cycle longer, production efficiency is lower, cost of labor is higher, the large and higher problem of production cost of labor strength.

Utility model content

The utility model provides a kind of production cycle shorter for above problem, and production efficiency is higher, and cost of labor is lower, the continuous production mould of little back splint that labor strength is lower and production cost is lower.

The utility model overcomes the above problems technical scheme used: provide a kind of little back splint continuous production mould, it comprises counterdie and patrix, and described patrix and counterdie are slidably connected, and is provided with successively from left to right punching groove on described counterdie, I shape punching groove, first cuts out groove, second cuts out groove, the first edging groove, crimp groove, pre-indent, forming tank and shaping groove, the side of described I shape punching groove is provided with the second edging groove, and described first cuts out groove and second cuts out the length that vertical range between groove equals little back splint, described pre-indent, between forming tank and shaping groove, be interconnected, described shaping groove is provided with opening at counterdie right-hand member, in described pre-indent, is provided with preloaded module, in described forming tank and shaping groove, is provided with forming module, described patrix upper punch hole slot, I shape punching groove, first cuts out groove, second cuts out groove, the first edging groove, position directly over crimp groove and the second edging groove is provided with drift one to one, pre-indent on described patrix, position directly over forming tank and shaping groove is provided with pressure head one to one.

Adopt after above device, compared with prior art, after the utility model is arranged on press, then under the cooperation of feed arrangement, first material strip goes out required all through holes in punching groove position; Enter subsequently I shape punching groove region, now rush I shape through hole, a side cutting edge and little back splint length direction and cut out, the length of now cutting edge equals the length of little back splint, and the width of cutting out is that material strip width deducts half that cut off after well width; Then enter second and cut out groove and the first edging groove region, to material strip opposite side turnover cutting edge, and cut out for the second time, make the only remaining tablet connection of cutting off groove size between adjacent two compact material; Enter subsequently crimp groove region, crimp processing is carried out in one end of blank; Enter pre-indent region, the blank after crimp is processed carries out precompressed processing again, makes that blank is follow-up is easier to moulding; Precompressed is processed rear blank and is entered forming tank moulding; Semi-finished product after moulding enter shaping in shaping groove; Finished product after shaping is from opening part discharging, and last workman only need cut off the tablet connecting between adjacent finished product; Above-mentioned whole production process only needs a workman and a press to complete, nine workmans and nine press have been saved compared to existing technology, greatly reduce cost of labor and equipment cost, and shortened the production cycle, the production time of each finished product has at least shortened the time of 9 times; Workman is without often carrying or placing blank simultaneously, and labour intensity is lower; Moreover whole production process is continuously and automatically, production efficiency is original more than 10 times.Therefore it is shorter to the utlity model has the production cycle, and production efficiency is higher, and cost of labor is lower, the feature that labor strength is lower and production cost is lower.

As improvement, between the first described edging groove and crimp groove, establish with cutting out hole slot, described second cuts out the twice that vertical range between groove and crimp groove left end equals little back splint length, and cut out hole slot on the second centre position of cutting out between groove and crimp groove left end, after cutting out hole slot and arranging, in punching course, middle punching at the connection tablet of adjacent blanks, make blank when moulding, connect tablet be unlikely to because of entire area larger, and there is the situation of distortion in the junction that occurs wrinkle or cause connecting tablet and blank, and then the yield rate while improving blank moulding, further reduce production cost of the present utility model.

As further improvement, the nearly opening of described forming module one end is provided with cut-out groove, and the left end of described cut-out groove is concordant with the right-hand member of shaping groove, cuts off after groove arranges, make semi-finished product after shaping, automatically cut off again, and then made the finished product that is from opening discharging, without wanting again workman to cut off by hand, the efficiency of cutting off is higher, can further improve production efficiency of the present utility model, reduce labor strength, thereby reduce production costs.

As further improving again, forming module in described forming tank and in shaping groove is integral type structure, the structure of integral type, be more conducive to the slip of blank on forming module, can effectively prevent that blank is unsmooth on forming module and cause material strip distortion, thereby cause the situation of the maintenance that stops production to occur, make stability in use of the present utility model better.

As further improving again, near described counterdie upper punch hole slot, be provided with guiding mechanism, described guiding mechanism comprises even number lead, one group between two of described lead, it is parallel that line and first between two leads of every group is cut out slot length direction, and two relative positions of lead of every group are provided with gathering sill, on described patrix, directly over lead, position is provided with the counterbore of accommodating lead, after guiding mechanism arranges, make stability and the directionality of material strip charging better, further improve stability in use of the present utility model.

As further improving again, in described shaping groove, the both sides of forming module all slidably connect shaping slide block, on described patrix shaping slide block directly over be provided with the pressure head that can make shaping slide block slide to forming module, between described shaping slide block and shaping groove inwall, be provided with resetting-mechanism, the reshaping device structure of this structure is simpler, small volume, for pure frame for movement, preparation cost is lower, and dependability is better, also be beneficial to the maintenance in later stage, to reduce maintenance cost.

As further improving, described resetting-mechanism comprises guide post and back-moving spring, and the inwall of described shaping Slot shaping module both sides is provided with through hole, and the axis of through hole is vertical with the axis of forming module, described guide post one end is fixedly connected with shaping slide block, the guide post other end is crossed through hole and back-moving spring socket, and this resetting-mechanism structure is simpler, is pure frame for movement, therefore preparation cost is lower, dependability is better, and service life is also longer, is convenient to the care and maintenance in later stage.
