Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of deep extrusion mould of cold forging part.
Background technology
At present in cold forging part process, often need to extrude a deep hole on cold forging part.Some parts such as various pins on piston pin, track pin, automobile chassis are all common deep extrusion parts; Also have some parts as the dehydrating shaft etc. of vehicle transmission sleeve pipe, fork-shaped sleeve pipe and washing machine, the deep hole in part is as preform, and then extrudes spline, step ring-type or tubular member.
Deep extrusion is the difficult problem being difficult in cold extruding technique avoid, general hole is when extruding, the ratio of hole depth and bore dia controls below 2.5, and the ratio of the hole depth of deep extrusion and bore dia is greatly about about 4.5: 1, reduction of area ε F is 20% ~ 50%, material is 20#, 35#, 45#, 20Cr, 20CrMnTi, 40Cr etc., as shown in Figure 4, existing extrusion die needs through following flow process in the production process of deep extrusion: blanking → twice chamfering → continuous grinding → twice anti-crowded → boring/cutting → run through just crowded → twice chamfering, instead squeeze for wherein twice and make deep hole forming, there is operation many, the defect that production time is long, add production cost, wait to improve.
Utility model content
Technical problem to be solved in the utility model is the deficiency overcoming background technology, a kind of deep extrusion mould for processing cold forging part is provided, this deep extrusion mould should be able to simplify production procedure, thus reduce process time, enhance productivity, reduce production cost, and have easy to operate, the simple feature of structure.
The technical scheme that the utility model adopts is: a kind of deep extrusion mould of cold forging part, is characterized in that: comprise demoulding push rod, die assembly, floating guiding cover, upper die component, drift and several springs; Die assembly is fixedly connected with floating guiding cover, and floating guiding cover can slide up and down to be positioned in the frame of press by guide holder, and demoulding push rod to be fixed in frame and vertically to stretch in the nib of die assembly upward, and spring is arranged on the bottom of die assembly; Upper die component is connected with press, and drift is vertically fixed on the bottom of upper die component and overhangs downwards, and drift is corresponding up and down with the nib of die assembly after being passed down through the through hole of floating guiding cover.
The inwall of described guide holder is coordinated with the outer wall that floating guiding overlaps by the guide rail vertically arranged.
Described spring is nitrogen spring, and several springs circumference centered by demoulding push rod is evenly arranged.
Described die assembly comprises traveling table and is fixed on the pattern of traveling table center, and the middle part of pattern is shaped with described nib.
The beneficial effects of the utility model are: the die assembly in the utility model can move down along with floating guiding cover, reduce the restriction that die assembly extends workpiece, utilize demoulding push rod to form backward extrusion to workpiece simultaneously, workpiece is extended towards the direction contrary with drift, can disposable formation deep hole (as shown in Figure 3), without the need to through twice extruding, simplify production procedure, thus reduce process time, enhance productivity, reduce production cost, and have easy to operate, the simple feature of structure.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, the deep extrusion mould of a kind of cold forging part described in the utility model, general and press 3 supports the use.
Described extrusion die comprises demoulding push rod 9, die assembly 8, floating guiding cover 7, upper die component 6, drift 5 and several nitrogen springs 2.Die assembly comprises horizontally disposed traveling table 8-1 and is fixed on the pattern 8-2 of traveling table center, the middle part of pattern offers the nib (stock 4 for place work piece) vertically arranged, traveling table is fixedly connected with by screw with floating guiding cover.Floating guiding cover can slide up and down to be positioned on pedestal 1 by guide holder 10, pedestal is fixed on bottom the frame of press 3, and the inwall of guide holder is coordinated with the outer wall that floating guiding overlaps (outer wall that floating guiding overlaps can be offered groove or install slide block) by the guide rail vertically arranged.Demoulding push rod to be fixed in frame and vertically to stretch into upward in the nib of pattern, and described nitrogen spring circumference centered by demoulding push rod is evenly arranged in the bottom of die assembly, and the upper end of nitrogen spring supports die assembly, and lower end abutment is on pedestal.Upper die component is connected with the hydraulic means of press, and drift is vertically fixed on the bottom of upper die component and overhangs downwards, and drift is corresponding up and down with the nib of die assembly after being passed down through the through hole of floating guiding cover, and the size of upper die component is greater than the size of through hole.
Operation principle of the present utility model is:
1, as shown in Fig. 2-1, under the effect of press, when upper die component presses down, first push down floating guiding cover, when continuing to press down, by floating guiding cover, die assembly is pressed down, and compressed nitrogen spring;
2, as shown in Fig. 2-2, when press continues to press down, drift can extrude blank, simultaneously die assembly compressed nitrogen spring;
3, as Figure 2-3, when press continues to press down, because die assembly continues to move down, simultaneously because demoulding push rod is motionless, make stock by backward extrusion, stock upper end and drift are that rightabout extends, and depart from die assembly (all not departing from) gradually;
4, as in Figure 2-4, when press stroke terminates to return, drift band is lived product and is departed from die assembly, and when continuing backhaul, product departs from drift by floating guiding cover, completes deep extrusion.
