Abstract
The invention discloses a three-dimensional trimming die capable of repairing parts quickly. The die comprises an upper die frame (1), an upper die seat (2), a discharging plate (3), upper punches (4), lower punches (5), a female die (6), a supporting plate (7), stop pieces (8), elastic pieces (9) and a lower die frame (10), wherein the upper die frame (1) is vertically and glidingly connected with the lower die frame (10) through pins; the elastic pieces (9) are arranged in the lower die frame (10); the supporting plate (7) is arranged on the elastic pieces (9); the female die (6) is arranged on the supporting plate (7); the lower punches (5) and the stop pieces (8) are arranged in the female die (6); the upper die seat (2) is arranged in the upper die frame (1) facing the lower die frame (10); the discharging plate (3) is arranged on the upper die seat (2); the upper punches (4) are arranged in the discharging plate (3). The lower punches (5) fixed on the supporting plate (7) are separated from cutting edges of the female die (6) through the stop pieces (8), so that the female die can be directly repaired online, the quality of a forging is improved, and the production efficiency is improved.
Description
Technical field
The present invention relates to Forging Technology technology, the mould of specifically a kind of energy quick repairs exploded perspective trimming.
Background technology
More and more three-dimensional part adopts forging processing at present, and because the cutting edge of die cutting overlap is easy to wear, along with the increase of output, for ensureing forging trimming quality, the number of times repairing cutting edge of die in production process increases.When cutting process is embraced in employing, cutting edge of die block by low punch, cannot realize repairing cutting edge of die online, just can repair after needing to split out die, often waste a large amount of time to go to dismantle die, and the time of dismounting die is more than the time of repairing needed for die, not only wastes a large amount of manpower financial capacity but also affects production efficiency.
Summary of the invention
The object of this invention is to provide one makes low punch be separated with cutting edge of die, and finally realize without the need to dismantling die, direct-on-line can place under repair to cutting edge of die, reaches the mould of the energy quick repairs exploded perspective trimming of enhancing productivity.
In order to realize object of the present invention, the technical solution used in the present invention is:
The mould of a kind of energy quick repairs exploded perspective trimming, be made up of top mold frame, upper bolster, stripper, upper punch, low punch, die, gripper shoe, block piece, elastic component, lower mold holder, top mold frame is connected in sliding up and down with lower mold holder by pin, elastic component is provided with in lower mold holder, elastic component is provided with gripper shoe, gripper shoe is provided with die, low punch and block piece is provided with in die, upper bolster is being provided with in the top mold frame of lower mold holder, upper bolster is provided with stripper, in stripper, is provided with upper punch.
What described die adopted is straight cutting edge, and described straight cutting edge height is 10-20mm, and straight cutting edge expands 1.5-2mm outward with lower part, so that cutting edge of die is repaired.
Described gripper shoe is connected by elastic component with lower mold holder.
Described block piece bar portion is provided with screw thread, is connected be lifted in die by nut, realizes its effect during use by tightening nut.
Described block piece local is longitudinally through die.
Beneficial effect of the present invention is:
Instant invention overcomes and embrace the difficult problem that cutting process cannot repair die online, save the time splitting out die, not only increase product quality but also improve production efficiency.
Accompanying drawing explanation
Fig. 1 is that the embodiment of the present invention repairs a die the front view of three-dimensional edger assembling of state;
Fig. 2 is that the embodiment of the present invention does not repair a die the three-dimensional edger part of the lower die front view of state;
Fig. 3 is barrier structures schematic diagram of the present invention.
Detailed description of the invention
During embody rule, on the edger of the three-dimensional crankshaft forging of particularly suitable of the present invention.Therefore below with the edger of three-dimensional crankshaft forging for specific embodiment being described in further details the present invention by reference to the accompanying drawings.
A mould for energy quick repairs exploded perspective trimming, is matched by upper die and lower die and forms, wherein:
Patrix is made up of top mold frame 1, upper bolster 2, stripper 3, upper punch 4.Upper bolster is fixed in top mold frame 1 by voussoir, and upper punch 4 is fixed in upper bolster 2 by screw rod, and stripper 3 is lifted on upper bolster 2 by bar;
Counterdie is made up of lower mold holder 10, elastic component 9, gripper shoe 7, block piece 8, die 6, low punch 5.Elastic component is arranged on bottom, top is provided with gripper shoe 7, low punch 5, die 6 is provided with above gripper shoe 7, low punch 5 is arranged in die 6, low punch 5 is fixed in gripper shoe 7 by screw rod, block piece 8 is fixedly lifted in die 6 by nut, and die 6 is then fixed in lower mold holder 10 by voussoir.
Top mold frame is connected in sliding up and down with lower mold holder by pin.
When being in normal production status, block piece 8 is lifted on inside die 6 by nut, does not affect moving up and down under the effect of elastic component 9 of gripper shoe 7.
When needing to realize object of the present invention, pressed down by patrix, upper punch 4 is made to contact with low punch 5 and force elastic component 9 to be regained, form gap between gripper shoe 7 and die 6, finally make low punch 5 depart from cutting edge completely, the nut of degree of tightness constant resistance part 8, block piece 8 is made to be placed in gripper shoe 7 with in the gap of die 6, block piece 8 half-twist, make its across at block piece 8 in the escape groove of die 6, for the reset of barrier support plate 7 and low punch 6.After completing above action, patrix is up, until equipment gets back to top dead-centre.Now, the personnel of repairing a die can realize placing under repair to cutting edge of die online, eliminate dismounting die institute's time spent, also can improve the quality of products and enhance productivity simultaneously.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and change; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
