The push-off device ensures that the ultrathin long rod is stable when being subjected to the impact load and realizes that the push-off rod pushes off a forged part efficiently and safely.
Description
Technical field:
The utility model relates in a kind of multistation automatic forging press field the ejecting device of used ejecting device, particularly a kind of ultra-fine stock in each station upsetting process.
Background technology:
Automatic forging press push-off pin portion draw ratio requires elongate rod can guarantee that in push it has suitable diameter to satisfy its enough release stroke again always, unstability can appear when not so the elongate rod under the push-off pin effect was hit load, can't realize releasing action, so ultra-fine all the time long rod part all adopts the method manufacturing of machining.The part efficient of making by cutting way is low, intensity difference and waste material, and the manufacturing cost height more and more can't be met the need of market.
The utility model content:
Technical problem to be solved in the utility model is the problem that produces unstability when overcoming the push-off pin elongate rod that exists in the background technology and being hit load, and provide a kind of ejecting device of ultra-fine stock, the ejecting device of this ultra-fine stock can satisfy when making elongate rod be hit load on automatic forging press not unstability, has realized that the push-off pin highly effective and safe releases product.
The invention for solving the technical problem can reach by following technical solution: the ejecting device of this ultra-fine stock comprises the ultra-fine stock release pin of fixedlying connected with push-off pin, push-off pin left end head is a ring flange, also comprising floats releases cover, the lower support piece, fairlead, the middle part back-up block, the right end portion of described push-off pin places to float releases cover inner chamber left end, release pin at the fixedly connected lower support piece of the root that is connected with push-off pin, the release of floating is overlapped the outside and is with fairlead, the outer lug boss of releasing the cover right-hand member of floating cooperates with the inner convex platform of fairlead inner chamber left end, float and release cover right-hand member head, release pin and pass the middle part back-up block by the fixedly connected middle part of back-up ring back-up block; Float to release between cover and fairlead, unsteady release cover and push-off pin and be matched in clearance.
Described push-off pin outer surface axially has groove, and the release cover left end inner surface that floats is fixed with guide finger, and guide finger slides in the axial groove of push-off pin outer surface; The left end outer surface of the outer lug boss of described unsteady release cover right-hand member axially has groove, is fixed with guide finger on the inner convex platform of fairlead left end inner chamber, and guide finger slides in the axial groove of the release cover outer surface that floats.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the ejecting device of this ultra-fine stock is owing to adopt said structure, the middle part that has guaranteed ultra-fine stock release pin has the middle part back-up block to support, the root of releasing pin has back-up block to fix, make it possess the stable condition of middle part and the support of two places, bottom, unstability can not take place thereby make elongate rod release pin, guaranteed the operation of the normal safety of ejecting mechanism under stressed situation.With relying on part high speed upsetting manufacturing on automatic forging press of machining originally, production efficiency and stock utilization have been improved greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-push-off pin, 2-float and release cover, 3-lower support piece, and the 4-fairlead, 5-releases pin, 6-middle part back-up block, 7-guide finger, 8-back-up ring, 9-guide finger.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, the ejecting device of this ultra-fine stock comprises push-off pin 1, the ultra-fine stock of fixedlying connected with push-off pin 1 is released pin 5, push-off pin 1 left end head is a ring flange, also comprising floats releases cover 2, lower support piece 3, fairlead 4, middle part back-up block 6, the right end portion of described push-off pin 1 places to float releases cover 2 inner chamber left ends, release pin 5 at the fixedly connected lower support piece 3 of the root that is connected with push-off pin 1, the release of floating is overlapped 2 outsides and is with fairlead 4, the outer lug boss of releasing cover 2 right-hand members of floating cooperates with the inner convex platform of fairlead 4 inner chamber left ends, float and release cover 2 right-hand member heads, release pin 5 and pass middle part back-up block 6 by back-up ring 8 fixedly connected middle part back-up blocks 6; Float to release cover 2 with fairlead 4, float release overlap 2 and 1 of push-off pin be matched in clearance; Described push-off pin 1 outer surface axially has groove, and the release cover 2 left end inner surfaces that float are fixed with guide finger 7, and guide finger 7 slides in the axial groove of push-off pin 1 outer surface; The left end outer surface that the outer lug boss of 2 right-hand members is overlapped in described unsteady release axially has groove, is fixed with guide finger 9 on the inner convex platform of fairlead 4 left end inner chambers, and guide finger 9 slides in the axial groove of release cover 2 outer surfaces that float.
The ejecting device movement structure principle of this ultra-fine stock is: in the time of on releasing the ring flange that masterpiece is used in push-off pin 1 left end head, push-off pin 1 moves right and promotes lower support piece 3 and together moves right with releasing pin 5, drives to float to release and overlaps 2 and together move right finish this push when the left end ring flange of push-off pin 1 will contact with the left end of fairlead 4 thereby promote middle part back-up block 6 when contact with middle part back-up block 6.This structure is the support that there is middle part back-up block 6 middle part that guaranteed to release pin 5, thereby making it stable condition that possesses bottom and the support of two places, middle part make elongate rod release pin 5 unstability can not take place, guarantee the operation of the normal safety of ejecting mechanism under stressed situation.
