Abstract

The utility model provides a closed forging die of disk parts, used on a common hot die forging press. The closed forging die is composed of a lower die holder, a female die fixed on the lower die holder, a lower knockout rod, an upper die holder, a punch fixed to the middle of the upper die holder, and a male die, wherein the female die is a die cavity part of the die; after positioned by a shaft neck of the punch, the male die is connected with the upper die holder via a screw bolt and a spring sheathed on the screw bolt; the male die is simultaneously used as the elastic stripper plate of the punch. The upper die holder is provided with an annular chamber protruding downward and fitted with the excircle of the female die into a guide lock ring. The die can carry out closed type forging of disc parts, such as gears, on the common hot die forging press, causes no flap edge material wastage, averagely saves materials by 10-15%, saves working procedures of edge cutting and machine work, shortens technological process and lowers manufacture cost.

Description

Disk-like accessory closed-die forging mould
Technical field
The utility model belongs to the closed-die forging technical field, relates in particular to the closed-die forging mould of disk-like accessory.
Background technology
Non-trimming forges and refers to that forging does not produce overlap in the forging process, forges (open type forging) with respect to traditional overlap that has, and it is called closed-die forging.Closed-die forging belongs to the finish forge category, is one of nearly clean shape technology in the forging industry.
Disk-like accessory forging ' s block dimension precision height such as sedan gear-box gear for example, draft angle is little.At present, replenish mach method after domestic common employing open type is forged and reach supply of material requirement.The shortcoming that this method exists is as follows: (1) open type has the forging overlap after forging, and needing increases the operation of cutting edge together, and general, the overlap of forging has accounted for 10~40% of blank weight, has so just wasted raw material, increases the material cost; (2), to make forging meet the drawing requirement, need to increase machining processes, thereby extended technological process, wasted cost.
Summary of the invention
To adopt open type to forge the shortcoming that the additional mach method in back exists cost of idleness, technological process length in order solving to have now, to the utility model proposes a kind of disk-like accessory closed-die forging mould that uses at the ordinary hot drop press as disk-like accessory forging such as sedan gear-box gears.
For this reason, the technical solution of the utility model is: disk-like accessory closed-die forging mould, form by die shoe, the bottom knockout bar, the upper bolster that are fixed on die on the die shoe, die bottom, drift, the punch that is fixed in the middle of the upper bolster, die is the die cavity part of mould, it is characterized in that: behind the axle journal location of punch with drift, be connected on the upper bolster by bolt, the spring that is enclosed within on the bolt, punch is simultaneously as the elasticity stripper of drift; Upper bolster is provided with the ring-like chamber that stretches out downwards and cooperates formation guiding snap close with the die cylindrical.
As further improvement of the utility model, be on die shoe, to be provided with the cooling duct to be communicated with the die inner chamber.
The utility model is simple in structure, can realize the disk-like accessory closed-die forging at the ordinary hot drop press.By the location between guiding snap close assurance punch, the die, in use, punch is before the contact blank, and the guiding snap close cooperates, guarantees the axiality requirement of disk-like accessory; By the bottom knockout bar forging is ejected die, by spring make punch with respect to drift to bottom offset, as the loading and unloading material device, in case forging be bonded on the drift can not the demoulding; On die shoe, be provided with the cooling duct, the convenient cooling medium that injects.Adopt this mould to realize on the ordinary hot drop press disk-like accessory as gear etc. is carried out closed-die forging, non-trimming spillage of material, average economical with materials 10~15%.Simultaneously, also save side cut operation, machining processes, shortened technological process, reduced manufacturing cost; The forging quality height of producing, dimensional accuracy is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Disk-like accessory closed-die forging mould as shown in Figure 1, the drift 5, the punch 6 that are fixed in the middle of the upper bolster 7 by die shoe 1, the bottom knockout bar 2 that is fixed on die 3 on the die shoe, die bottom, upper bolster 7, by screw 10 are formed, die 4 is the die cavity part of mould, behind the axle journal location of punch 6 with drift 5, be connected on the upper bolster 7 by bolt 9, the spring 8 that is enclosed within on the bolt, punch 6 is simultaneously as the elasticity stripper of drift 5; Upper bolster 7 is provided with the ring-like chamber that stretches out downwards and cooperates formation guiding snap close with die 3 cylindricals.
Be provided with cooling duct 11 and be communicated with die 3 inner chambers on die shoe 1, this is to add cooling medium for convenience.In the actual fabrication, cooling duct 11 can not be provided with yet, and at this moment needs to dismantle mould and adds cooling medium.

Claims (2)

1, disk-like accessory closed-die forging mould, form by die shoe, the bottom knockout bar, the upper bolster that are fixed on die on the die shoe, die bottom, drift, the punch that is fixed in the middle of the upper bolster, die is the die cavity part of mould, it is characterized in that: behind the axle journal location of punch with drift, be connected on the upper bolster by bolt, the spring that is enclosed within on the bolt, punch is simultaneously as the elasticity stripper of drift; Upper bolster is provided with the ring-like chamber that stretches out downwards and cooperates formation guiding snap close with the die cylindrical.
2, disk-like accessory closed-die forging mould according to claim 1 is characterized in that: described die shoe is provided with the cooling duct and is communicated with the die inner chamber.
