Abstract
The utility model relates to the compound die of two adjustable punching distance of elongated hole workpiece, comprises the upper bolster, the die shoe that are mounted opposite, and upper bolster bottom interval is provided with fixing drift and a removable drift; Described upper bolster is provided with dovetail groove; Dovetails is provided with above removable drift; Described dovetails is arranged in dovetail groove; Described drift comprises guide part and operate portions; Described guide part is arranged on the below of operate portions; Described guide part is Tapered Cup, and the periphery in described operate portions working front edge face is provided with alloy hoop; Described alloy hoop selects low nickel-chrome-molybdenum alloy to make.The utility model is by fixing the design of drift and movable punching head, can require to adjust the one time punching molded diplopore of distance between drift according to pitch-row, not only increase production efficiency and ensure that holes centre-to-centre spacing, thus guarantee workpiece processing quality, by the structural design to drift, not only extend the service life of punch, and improve punching hole precision and quality.
Description
Technical field
The utility model relates to a kind of compound die, is specifically related to the compound die of a kind of pair of elongated hole workpiece by adjustable punching distance.
Background technology
Two elongated hole workpiece is part conventional in ribbon conveyer, pitch-row in different two elongated hole workpiece is different, in its production process, punching technology is processed at twice, this production method not only cost is high, efficiency is low and waste time and energy, its holes centre-to-centre spacing error is also very large, be difficult to ensure crudy, in addition, in industry, the pierce punch of common use is in use because rubbing with steel part always, cause wearing and tearing, the size causing the hole processed is changing always, precision less than guarantee, the situation of wear out failure also occurs repeatedly.During the hole that if desired requirement on machining accuracy is higher, just need frequently to change drift, the time that wastes, with artificial, reduces production efficiency.
Utility model content
The utility model object provides the different two elongated hole of a kind of adaptation apart from processing to overcome the deficiencies in the prior art, and guarantee crudy, improves drift service life and the compound die of the adjustable punching distance of two elongated hole workpiece of enhancing productivity.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pair of elongated hole workpiece compound die of adjustable punching distance, comprises the upper bolster, the die shoe that are mounted opposite, and described upper bolster bottom interval is provided with fixing drift and a removable drift; Described upper bolster is provided with dovetail groove; Dovetails is provided with above described removable drift; Described dovetails is arranged in dovetail groove; Described die shoe is provided with die; Described drift comprises guide part and operate portions; Described guide part is arranged on the below of operate portions; Described guide part is Tapered Cup, and the periphery in described operate portions working front edge face is provided with alloy hoop; Described alloy hoop selects low nickel-chrome-molybdenum alloy material to make.
Improve further as the utility model, bottom described upper bolster, be respectively equipped with guide pin bushing, guide rod with both sides, described die shoe top, described guide rod is inserted in guide pin bushing; Described fixing drift and guide pin bushing are fixed on upper bolster respectively by epoxy resin.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Two elongated hole workpiece of the utility model scheme compound die of adjustable punching distance, by the design of fixing drift and movable punching head, can require to adjust the one time punching molded diplopore of distance between drift according to pitch-row, not only increase production efficiency and ensure that holes centre-to-centre spacing, thus guarantee workpiece processing quality, by the structural design to drift, not only extend the service life of punch, and improve punching hole precision and quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of of the present utility model pair of elongated hole workpiece with the compound die of adjustable punching distance;
Accompanying drawing 2 is that the A-A of of the present utility model pair of elongated hole workpiece with the compound die of adjustable punching distance is to sectional view;
Wherein: 1, upper bolster; 2, die shoe; 3, fixing drift; 4, removable drift; 5, dovetail groove; 6, dovetails; 7, die; 8, guide pin bushing; 9, guide rod; 10, epoxy resin; 11, guide part; 12, operate portions; 13, alloy hoop.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1,2 is the compound die of the adjustable punching distance of a kind of pair of elongated hole workpiece described in the utility model, comprises the upper bolster 1, the die shoe 2 that are mounted opposite, and described upper bolster 1 bottom interval is provided with fixing drift 3 and a removable drift 4; Described upper bolster 1 is provided with dovetail groove 5; Dovetails 6 is provided with above described removable drift 4; Described dovetails 6 is arranged in dovetail groove 5; Described die shoe 2 is provided with die 7, and described drift comprises guide part 11 and operate portions 12; Described guide part 11 is arranged on the below of operate portions 12; Described guide part 11 is Tapered Cup, and the periphery in described operate portions 12 working front edge face is provided with alloy hoop 13; Described alloy hoop 13 selects low nickel-chrome-molybdenum alloy material to make; Fix in drift 3 and removable drift 4 punching course, first be that guide part 11 is exerted pressure punching in advance, then operate portions 12 carries out formal punching, even if, guide part 9 is subject to a little wearing and tearing, also do not affect crudy, the design of alloy hoop 11 improves the wearability of drift working face and hardness and toughness, not only extends the service life of punch but also improves punching hole precision and quality.
Bottom described upper bolster 1, be respectively equipped with guide pin bushing 8, guide rod 9 with both sides, described die shoe 2 top, described guide rod 9 is inserted in guide pin bushing 8; Described guide rod 9 is inserted in guide pin bushing 8, is matched by guide rod 9 and guide pin bushing 8, patrix is fallen more accurate; Described fixing drift 3 is fixed on upper bolster 1 respectively by epoxy resin 10 with guide pin bushing 8, the processing of mould is simplified greatly, reduces the cost of manufacture of mould.
By the design of fixing drift 3 and movable punching head 4, can require that the distance between adjustment drift realize one time punching molded diplopore according to pitch-row, not only increase production efficiency and ensure that holes centre-to-centre spacing, thus ensure workpiece processing quality.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
