Description
Technical field:
The utility model relates to a kind of progressive stamping mould that is used for being fit to the lead frame punching press, specifically a kind of progressive stamping mould for the treatment of pressing sheet material spare positioning accuracy that improves.
Background technology:
For sheet material spare,, in progressive die, want some steps just can finish such as the punching production of lead frame band.An important problem is located exactly in the progressive stamping mould, and each step all will accurately locate when producing, and could guarantee the precision of punching press.A kind of method commonly used is exactly to go out locating hole earlier on sheet material, and the locating pin that cooperates with locating hole is set on the mould, with the location of locating pin realization to product.But new problem has just had, and how punching out accurately goes out locating hole on sheet material spare, guarantees the position of locating hole on stock layout.To be solved in the utility model is exactly this problem.
Summary of the invention:
The utility model provides a kind of progressive stamping mould of positioning accuracy just that improves, and can improve positioning accuracy.
The utility model is achieved in that and comprises die, punch, be fixed with two guide rails that band is just located on the die block, gap between two guide rails is a sheet material spare locating slot, it is characterized in that: further comprising at least two to sheet material spare accurate positioning device, this device is made up of briquetting and locating piece, briquetting is fixed on the stripper of punch, a guide rail is provided with the gathering sill that with locating piece cooperate vertical with sheet material spare locating slot, locating piece is arranged in the described gathering sill, the inclined-plane that cooperatively interacts is arranged on briquetting and the locating piece, when matched moulds, briquetting promotes locating piece by the inclined-plane and advances in sheet material spare locating slot, push sheet material spare to the opposite side guide rail,, so just can improve positioning accuracy to eliminate the gap between sheet material spare and the guide rail.
In order to prevent way rub, improve its service life, described locating piece adopts wear-resisting carbide alloy to make, and is inlaid with the wear-resisting abaculus that Hardmetal materials is made with sheet material spare contact site on another guide rail corresponding with the location pushing block.
Regulate the pressure of locating piece for convenience to sheet material spare, stripper is provided with by the compression spring and regulates the briquetting buffer unit that bolt is formed, have the briquetting installing hole on the stripper, the briquetting upper end has and regulates spiral shell and joins the screw that bolt closes, regulate bolt briquetting is fixed in the installing hole, the compression spring is located between briquetting and the fixation clip.By regulating bolt, can regulating spring power.
Locating piece is advanced by guide rail one thruster the utility model when the matched moulds by adopting, sheet material spare is adjacent on another guide rail, thereby eliminated the gap between sheet material spare and the guide rail, thereby improved positioning accuracy, and bear pushing block pressure position, location on locating piece and the opposite side guide rail and make by carbide alloy, precision is high and not easy to wear.Reload buffer device on the briquetting makes locating piece to raw material, and especially the damage of thin material is little, and regulates more convenient.
Description of drawings:
Fig. 1 is the utility model structural representation when die opening state.
Fig. 2 is the utility model structural representation when the matched moulds state.
Fig. 3 is the plan view during the pushing block work of location when full mould state.
Fig. 4 is along A-A line profile among Fig. 3.
The specific embodiment:
The utility model is provided with two to sheet material spare accurate positioning device, this accurate positioning device is made up of briquetting 6 and locating piece 2, structure as depicted in figs. 1 and 2, have the briquetting installing hole on the stripper 7 of punch, the briquetting buffer unit is made up of compression spring 10 and adjusting bolt 14, briquetting 6 upper ends have and regulate the screw that bolt 14 cooperates, pressing plate 8 is fixed on the stripper 7 by bolt 13, regulating bolt 14 is fixed on briquetting 6 in the installing hole, compression spring 10 is located between briquetting and the pressing plate, briquetting 6 lower ends have with locating piece 2 on the inclined-plane 12 that cooperatively interacts.
Be fixed with the pair of guide rails 4,5 that sheet material spare 3 is just located on the die block 9, Fig. 1 and Fig. 2 middle guide 4 do not draw.Guide rail cooperates as shown in Figure 3 with sheet material spare, and the gap between two guide rails 4,5 is a sheet material spare locating slot, and sheet material spare 3 is passed through by the locating slot between guide rail 4 and 5, and with guide rail 4,5 certain clearance is arranged.Guide rail 4 is provided with the gathering sill that with locating piece 2 cooperate vertical with sheet material spare locating slot, locating piece 2 is arranged in the gathering sill, there is the inclined-plane 12 that cooperates with inclined-plane, briquetting 6 lower end locating piece 2 rear ends, when matched moulds, briquetting 6 promotes locating piece 2 by inclined-plane 12 and advances in sheet material spare locating slot, and sheet material spare 3 is pressed on the opposite side guide rail 4.Locating piece 2 adopts wear-resisting carbide alloy to make, and is inlaid with the wear-resisting abaculus 1 that Hardmetal materials is made with sheet material spare contact site on another guide rail 4 corresponding with locating piece 2.
When die opening state, as shown in Figure 1, briquetting 6 does not contact with locating piece 2, and locating piece 2 has certain activity in the horizontal direction, with sheet material spare certain clearance 11 is arranged, and sheet material spare 3 can freely enter mould.
When the matched moulds state, as shown in Figure 2, spring 10 is given 6 one downward power of briquetting, and the inclined-plane by briquetting 6, and masterpiece is used on the locating piece 2, forces it to do horizontal movement, and sheet material spare 3 is shifted onto with till wear-resisting abaculus 1 contacts.If power is big, the edge of sheet material spare 3 may arch upward because of the power that is subjected to level; Power is little, and possible sheet material spare 3 can not contact with wear-resisting abaculus 1, does not reach the effect of location.By regulating the bolt 14 that briquetting 6 links to each other with pressing plate 8, can regulate the size of this power, reach desirable effect.
