The invention relates to a multistage workstation forming die, in particular to a built-up hole punching device which comprises an upper die, a lower die, a hydraulic rod, an adjusting lever and a punch. The upper die is a convex die, the lower die is a concave die and is mounted on a lower die frame, the upper die is mounted on an upper die frame, the hydraulic rod, the adjusting lever and the punch are connected sequentially, the hydraulic rod is connected with a power arm of the adjusting lever, the punch is connected with a resistance arm of the adjusting lever, a groove is matched with a preset built-up hole in shape is formed in the convex die, a through hole for the hydraulic rod to penetrate out is formed in the upper die, the adjusting lever is arranged on the lower die frame, the punch penetrates the lower die and goes into the groove, and the top end of the punch and the groove are matched in shape. The defect that burrs are positioned in the direction of the convex die in the prior art is overcome, and the built-up hole punching device enables burrs of a pre-punched hole to be positioned in the direction of the convex die.
Description
Technical field
The present invention relates to a kind of multistage station mould, be specifically related to pore-forming punching machine.
Background technology
Along with the continuous progress of mold production process, punching during parts are generally produced by current each manufacturer and forming step are integrated in a secondary mould and carry out reducing costs, the drift of perforate is arranged on forming convax mould, before part to be processed is placed on molding concave die, forming convax mould moves to part place and completes part perforate by drift, and then forming convax mould moves on the shaping of part until fitted respectively with the die face of forming convax mould and molding concave die respectively in the two sides of part.
Conventional punching course is that punch rushes from top to bottom, but such punching press can make the burr of flange pre-punched hole be positioned at the position in the same way with flanging die, direction controlling for specific burr namely allow the burr of pre-punched hole be positioned at punch reverse position, then cannot use conventional perforating press.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pore-forming punching machine making the burr of pre-punched hole be positioned at position, punch direction.
For solving the problems of the technologies described above, the invention provides following technical scheme:
Pore-forming punching machine, comprise patrix and counterdie, wherein patrix is punch, counterdie is groove, counterdie is installed on lower mold holder, patrix is installed in top mold frame, also comprise the hydraulic stem connected successively, adjustment (adjusting) lever and drift, wherein hydraulic stem is connected with the power arm of adjustment (adjusting) lever, described drift and adjustment (adjusting) lever resistance arm be connected, punch is provided with and the groove being preset to hole shape and mating, described patrix is provided with the through hole passed for described hydraulic stem, lower mold holder place is located at by described adjustment (adjusting) lever, described drift runs through counterdie and is passed into described groove, the form fit of punch tip and described groove.
Adopt pore-forming punching machine of the present invention, there is following effect:
In specific works process, be placed between patrix and counterdie before this by section bar, then patrix docks with counterdie (patrix is by power drive), then drives adjustment (adjusting) lever to move by hydraulic stem; Hydraulic stem moves down, and adjustment (adjusting) lever resistance arm upwarps, and drift upwards pushes up die mould material, section bar is out of shape to the groove of patrix, thus completes default pore-forming.
The hydraulic stem that the present invention's utilization is arranged on patrix drives the adjustment (adjusting) lever motion being located at lower mold holder, make to be positioned at drift immediately below patrix groove to upper feeding, again because patrix is punch, counterdie is die, alike last section bar of being not difficult is the shape of a basin body, be provided with a cylinder at center to arch in basin body, and the burr that cylinder is shaped in cylinder not outside cylinder.The upper surface shape of such basin body is just comparatively regular.
If adopt existing patrix to move down the mode then resetted, then burr can be positioned at the outer surface of hollow cylinder, and such effect can affect the sight that basin body mainly sees depending on face and look.
Further, described hydraulic stem is hydraulically extensible bar, and hydraulically extensible bar is fixed on patrix, is provided with pad between described counterdie and lower mold holder, and described pad is provided with the through hole towards described adjusting rod power arm, and described through hole is provided with the fairlead penetrated for hydraulic stem.
Because hydraulic stem movement travel is longer, in order to prevent hydraulic stem from misplacing when flexible, ad hoc fairlead guides.
Further, between described counterdie and adjustment (adjusting) lever, be provided with back-moving spring, described pad offer the through hole passed through for described back-moving spring.
After patrix gos up, hydraulic stem moves, and adjustment (adjusting) lever can reset under the effect of back-moving spring, and drift also can fall.
Further, described back-moving spring is stage clip, and stage clip is connected with the resistance arm of adjustment (adjusting) lever.
When back-moving spring is stage clip, then stage clip is connected with the resistance arm of adjustment (adjusting) lever, and drift just can be made to decline.
Accompanying drawing explanation
Fig. 1 is the structural representation of pore-forming punching machine embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
