Abstract
The utility model discloses a hot forging die upper die automatic demolding device which comprises an upper top rod, a spacing board, an upper template, a pneumatic spring, a pad, a bolt, a slide block and a flat plate, wherein the bottom end of the slide block is connected with the upper template through the flat plate, the pneumatic spring is vertically arranged in the inner hole of the upper template, a slide rod downwards extends out, and the other end is connected on a fixing position with the bolt through the pad. The upper end of the upper top rod penetrates through the through hole of the spacing board and is connected with the extending end of the slide rod of the pneumatic spring to form an elastic straight moving mechanism, and the lower end is inserted in the top end hole of the upper die. Forging force upwards pushes the slide rod of the pneumatic spring through the upper top rod during the forging process, the energy storage pneumatic spring begins releasing accumulated energy when the slide block ascends, and the upper top rod is driven to downwards move to knock out a forging piece. Since demolding is betimes, the forging piece falls from a lower position, the surface is not easy to be collided, and meanwhile, forging piece displacement and module cleaning time are got, thereby being beneficial for improving production efficiency. The hot forging die upper die automatic demolding device is suitable for being used as a demolding device of a small-sized precise forging piece.
Description
Technical field
The utility model relates to a kind of forging die stripper, and specifically, the utility model relates to a kind of stripper that is located in the hot-forging die patrix.
Background technology
During the forging and pressing of forging press hot-die, ability was by the stripper launch mode after the forging of shaping was up to certain altitude with patrix usually, and the hysteresis demoulding strengthens the height of drop of shaping forging, easily causes forging surface bump injury.For the mach forging of common forgings and follow-up work surface, a little bump injury of surface allows, and the excessive tooth portion bump injury that easily causes of the gear height of drop of the forging of precision forging, particularly precision forging.The tooth portion of gear is the main transmission position of bearing load, does not allow to utilize by correction of the defect again.The hysteresis demoulding removes influences forging surface quality, has also reduced productive temp, is necessary further improvement.
The utility model content
The utility model is achieved through the following technical solutions technical goal.
Hot-forging die patrix automatic material separator device, it comprises upper ejector pin, limiting plate, cope match-plate pattern, air spring, pad, bolt, slide block and flat board.The bottom of described slide block is by the dull and stereotyped cope match-plate pattern that connects.Its improvements are: described air spring vertically-arranged is in the cope match-plate pattern endoporus, and slide bar stretches out down, and the other end is connected and fixed the position by pad and bolt.Described upper ejector pin is an elongate rod, and its upper end passes the through hole of limiting plate and the slide bar external part of air spring connects into the elasticity linear moving mechanism, and insert in the patrix topped hole lower end.
Air spring in the said structure is a nitrogen spring.
The utility model compared with prior art has following good effect:
1, the air spring vertically-arranged is in the cope match-plate pattern endoporus, and compact conformation is easy to manufacture;
2, air spring promotion upper ejector pin material returned action and slide block rise synchronously, because the demoulding is timely, forging falls from lower position, are difficult for the surperficial bump injury of generation;
3, in the demoulding of slide block backhaul initial stage forging, help forging displacement and clear modulo operation, improved production efficiency.
Description of drawings
Fig. 1 is the utility model structural profile schematic diagram, and upper ejector pin promotes to contract in the air spring among the figure.
Fig. 2 is that air spring promotion upper ejector pin moves down schematic diagram.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Hot-forging die patrix stripper shown in the drawings, it comprises upper ejector pin 1, limiting plate 2, cope match-plate pattern 3, air spring 4, pad 5, bolt 6, slide block 7 and dull and stereotyped 8.Slide block 7 bottoms of forging press connect cope match-plate pattern 3 by dull and stereotyped 8, and air spring 4 vertically-arrangeds are in cope match-plate pattern 3 endoporus, and slide bar 4.1 stretches out down.Air spring 4 other ends are connected and fixed the position by pad 5 and bolt 6.Described upper ejector pin 1 is an elongate rod, and its upper end passes the through hole of limiting plate 2 and slide bar 4.1 external parts of air spring 4 connect into the elasticity linear moving mechanism, and insert in the patrix topped hole lower end.During practical application, slide block 7 drives whole device and moves back and forth up and down, the forging force of excellent suitability for press forming is by pushing away the slide bar 4.1 of air spring 4 on the upper ejector pin 1, shorten situation shown in the accompanying drawing 1 in the slide bar 4.1 into, the air spring of accumulation of energy begins to discharge institute's accumulation of energy when slide block 4 rises, driving upper ejector pin 1 moves down the forging that will forge in the patrix and ejects.Because the demoulding is at the 7 backhaul initial stages of slide block, forging falls from lower position, is difficult for taking place surperficial bump injury, also wins forging displacement and clear modulo operation time simultaneously, helps enhancing productivity.
