Description
Technical field
The utility model relates to stamping technology field, particularly relates to a kind of Wire fastener bending die.
Background technology
As shown in Figure 4, be Wire fastener conventional in a kind of electronic product, in bending tabular, its one end is tabular, and the other end is arc-shaped, tabular has a through hole.This product adopts bending die bending forming, but after adopting common bending die processing, because the effect product of residual stress is easy to resilience, product can not reach the technical requirement of drawing, product quality is low, needs subsequent handling to repair, extends man-hour, add production cost, the serious product of resilience even produces to be scrapped.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, not easily produce resilience after providing a kind of product to be shaped, product quality is high, the Wire fastener bending die saved production cost.
The purpose of this utility model is achieved through the following technical solutions.Wire fastener bending die, comprise upper bolster, punch, die shoe, die, described punch has two, punch comprises convex module and roller, the upper end of two convex modules is rotatably connected on the left and right sides below upper bolster respectively, the lower end of convex module is rotationally connected roller, centre below upper bolster moves up and down connection one depression bar, the lower surface of depression bar is provided with two locating holes, die is fixedly connected on the upper surface of die shoe, the left and right sides of die upper surface is respectively equipped with groove, the bottom surface of groove is circular arc, the one side of groove near die center is perpendicular, groove is inclined-plane away from the one side at die center, inclined-plane is centroclinal to die from top to bottom, the centre of die upper surface is provided with two alignment pins.Adopt this mould, two products are shaped together, are then separated from centre by two products.Through hole in the middle of two product blanks processes in advance, during work, is placed on by blank on die, two through holes on blank are inserted in alignment pin location, patrix is descending, and the upper end of alignment pin enters two locating holes of depression bar lower surface, and blank pushed down by depression bar, patrix continues descending, spring-compressed, the groove of die is compressed into, when groove compressed into by punch in blank both sides by punch, blank is compressed into groove along groove inclined-plane by roller, finally forms two products linked together.When groove finally compressed into by punch, the center line of convex module is in vertical direction with an acute angle, the lower end of punch tilts to depression bar direction, roller produces active force on the arc surface of product towards tabular side, this active force eliminates the residual stress after product shaping, makes it not easily produce resilience, improves product quality, this mould can process two products simultaneously, and operating efficiency is high.
As preferably, the lower surface of described upper bolster is fixedly connected with middle plate, the lower surface of middle plate is fixedly connected with lower plate, the centre of upper bolster lower surface is provided with a shrinkage pool, spring is provided with in shrinkage pool, the centre of middle plate is provided with the first through hole, the centre of lower plate is provided with the second through hole, first through hole is greater than the second through hole, and described depression bar is T-shaped, and the upper end of depression bar is positioned at the first through hole, the lower end of depression bar is vertically stretched out from the lower surface of lower plate through the second through hole, punch is rotatably connected on the lower surface of lower plate, and structure is simple, processes easy for installation.
As preferably, the upper surface of described upper bolster is fixedly connected with a die shank, when patrix is installed on forcing press, and accurate positioning, easy for installation.
The beneficial effects of the utility model are, product not easily produces resilience after being shaped, and product quality is high, has saved production cost, and a mould two pieces, improves production efficiency high, and structure is simple, easy to operate.

Detailed description of the invention
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Figure 1 to Figure 2, Wire fastener bending die, be made up of patrix and counterdie, patrix comprises die shank 1, upper bolster 2, middle plate 3, lower plate 4, depression bar 10, punch 5, punch has two, the lower surface of upper bolster is fixedly connected with middle plate, the lower surface of middle plate is fixedly connected with lower plate, upper bolster, middle plate, lower plate is fixed together by screw and straight pin, the centre of upper bolster lower surface is provided with a circular shrinkage pool, spring 11 is provided with in shrinkage pool, the centre of middle plate is provided with the first circular through hole, the centre of lower plate is provided with the second circular through hole, the internal diameter of the first through hole is greater than the internal diameter of the second through hole, depression bar is T-shaped, the upper end of depression bar is positioned at the first through hole, the lower end of depression bar is vertically stretched out from the lower surface of lower plate through the second through hole, the lower surface of depression bar is provided with two circular locating holes.As shown in Figure 3, punch comprises convex module 51 and roller 52, and convex module is strip, its top and bottom are all in semi-cylindrical, and a manhole is offered in upper end, and there is opening lower surface, roller is arranged in opening, and roller is connected to convex module lower end by axis of rotation.The left and right sides of lower plate lower surface be respectively equipped with one recessed, the bottom of recessed longitudinal cross-section shape is circular arc, recessed opening part tilts to depression bar direction near the lower end of depression bar side, and the upper end of convex module is positioned at recessed and is connected in lower plate by an axis of rotation.Counterdie comprises die shoe 8, die 7 etc., the basic configuration of die is cuboid, die is fixedly connected on the upper surface of die shoe by screw, the left and right sides of die upper surface is respectively equipped with groove, and groove is through to trailing flank from the leading flank of die, and the bottom surface of groove is circular arc, the one side of groove near die center is perpendicular, groove is inclined-plane away from the one side at die center, and inclined-plane is centroclinal to die from top to bottom, and the centre of die upper surface is fixedly connected with two alignment pins 6.When upper and lower mould is separated, the vertical center line of punch does not overlap with the vertical center line of die groove floor circular arc, the vertical center line of die groove floor circular arc compared with the vertical center line of punch near the center of die.During work, be placed on die by blank 9, two through holes on blank are inserted in alignment pin location, and patrix is descending, the upper end of alignment pin enters two locating holes of depression bar lower surface, blank pushed down by depression bar, and patrix continues descending, spring-compressed, the groove of die is compressed in blank both sides by punch, when groove compressed into by punch, blank is compressed into groove along groove inclined-plane by roller, finally forms two products linked together 12.Patrix is up, is taken off by product from die, then the product linked together two cuts.When groove finally compressed into by punch, because the center line of convex module is in vertical direction with an acute angle, the lower end of punch tilts to depression bar direction, roller produces active force on the arc surface of product towards tabular side, this active force eliminates the residual stress after product shaping, makes it not easily produce resilience, improves product quality, this mould can process two products simultaneously, and operating efficiency is high.
The above is the utility model preferably detailed description of the invention, not limits practical range of the present utility model with this.The utility model can also have other embodiment, and only otherwise deviate from spirit of the present utility model, no matter in form what kind of conversion all drops within protection domain of the present utility model.
