Abstract
The invention discloses a composite die for trimming and piercing, comprising an upper die holder, a lower die holder, U-shaped plates disposed at the both ends of the lower die holder, a piercing punch holder fixedly held with the lower die holder, a piercing punch fixedly held on the piercing punch holder, cross arms installed on the U-shaped plates, ejectors fixedly held on the cross arms, a die holder installed on the lower die holder, a trimming die fixedly held on the die holder, pull rods installed above the U-shaped plates, a punch handle installed below the upper die holder, and a trimming punch fixedly held with the punch handle, wherein a tapered wedge is disposed between the upper die holder and the punch handle, and battens are disposed above the pull rods. The composite die for trimming and piercing simplifies procedures, reduces devices and floor area, and increases working efficiency.
Description
Technical field
The present invention relates to mould applications, relate in particular to a kind of edge-cutting and hole-punching composite die.
Background technology
In the prior art, punching and side cut are two operations separately, in daily production process, need to finish respectively this two operations by punching die and this two mold of shaving die respectively, so not only increase equipment and human cost, reduced simultaneously production efficiency.
Therefore, be necessary to provide a kind of edge-cutting and hole-punching composite die that solves the problems of the technologies described above.
Summary of the invention
Technical problem to be solved by this invention is: the edge-cutting and hole-punching composite die that provides a kind of and simplify working process, reduce cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of edge-cutting and hole-punching composite die, it comprises: upper bolster, die shoe, be arranged at the U-shaped plate at die shoe two ends, punching convex die holder with die shoe phase fixing, be immobilizated in the piercing punch on the punching convex die holder, be installed on the cross-arm on the U-shaped plate, be immobilizated in the backing-out punch on the cross-arm, be installed on the die socket on the die shoe, be immobilizated in the trim die on the die socket, be installed on the pull bar of U-shaped plate top, be installed on the punch shank of upper bolster below, side cut punch with punch shank phase fixing, be provided with wedge between described upper bolster and the punch shank, the top of described pull bar is provided with batten.
The invention has the beneficial effects as follows: the present invention is installed on the upper bolster by the side cut punch, and trim die and piercing punch device are on die shoe.When the side cut punch move downward form shearing force and finish side cut with trim die after, continue to move downward, make workpiece and piercing punch form shearing force to finish punching.Eject workpiece by backing-out punch at last and finish whole procedure.This edge-cutting and hole-punching composite die has been simplified operation, has reduced equipment and floor space, has improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of edge-cutting and hole-punching composite die.
Among Fig. 1: 1, upper bolster, 10, punch shank, 100, the edge-cutting and hole-punching composite die, 11, the side cut punch, 12, wedge, 2, die shoe, 3, the U-shaped plate, 30, cross-arm, 31, backing-out punch, 4, the punching convex die holder, 5, piercing punch, 6, die socket, 60, trim die, 7, pull bar, 70, batten.
The specific embodiment
See also Fig. 1, a kind of edge-cutting and hole-punching composite die 100, it comprises: upper bolster 1, die shoe 2, be arranged at the U-shaped plate 3 at die shoe 2 two ends, punching convex die holder 4 with die shoe 2 phase fixings, be immobilizated in the piercing punch 5 on the punching convex die holder 4, be installed on the cross-arm 30 on the U-shaped plate 3, be immobilizated in the backing-out punch 31 on the cross-arm 30, be installed on the die socket 6 on the die shoe 2, be immobilizated in the trim die 60 on the die socket 6, be installed on the pull bar 7 of U-shaped plate 3 tops, be installed on the punch shank 10 of upper bolster 1 below, side cut punch 11 with punch shank 10 phase fixings, be provided with wedge 12 between described upper bolster 1 and the punch shank 10, thereby make fixing between upper bolster 1 and the punch shank 10, the top of described pull bar 7 is provided with batten 70, thereby pull bar 7 is immobilizated on the slide block of stamping machine, be connected by pin between described U-shaped plate 3 and the cross-arm 30, described U-shaped plate 3 is provided with the oval conduit of accommodating pin.
The present invention is installed on the upper bolster 1 by side cut punch 11, and trim die 60 and piercing punch 5 devices are on die shoe 2.When side cut punch 11 move downward form shearing forces and finish side cut with trim die 60 after, continue to move downward, make workpiece and piercing punch 5 form shearing forces to finish punching.When punch press makes progress backhaul,, and then by backing-out punch 31 workpiece is ejected cross-arm 30 pull-ups by U-shaped plate 3 and pull bar 7, thereby finish whole procedure.This edge-cutting and hole-punching composite die 100 has been simplified operation, has reduced equipment and floor space, has improved operating efficiency.
