Relativeness is altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.
Embodiment 1
As shown in Figs. 1-2, the vertical forging forging mold of the steering arm shaft of the utility model, the steering arm shaft by from top to bottom according to
The first axle of secondary connection, the second axis and third axis are constituted, and the forging mold includes upper mold 1, lower die 2, is located at 1 lower die 2 of upper mold
Between type chamber, bridge portion 8 and storehouse portion 9, the type chamber is successively arranged from top to bottom to be adapted with first axle, the second axis, third axis
The first type chamber 3, second type chamber 4 and third type chamber 5, second type chamber 4 turns left from the right side and is made of teeth portion type chamber 6 and axle portion type chamber,
The die joint 7 of forging mold is set on the center line of second type chamber 4；The circular inner wall of the first type chamber 3 is equipped with 3 ° of draft
Angle α, the circular inner wall on 5 top of third type chamber are equipped with 1 ° of draft angle β, and the length of 5 lower part of third type chamber is 20mm.The type chamber
It is connected by bridge portion 8 with storehouse portion 9, the storehouse width in storehouse portion 9 is 30-35mm, and storehouse depth is 3.5mm.2 bottom of lower die is along the vertical direction
It is equipped with the mandril 10 for ejecting workpiece, the diameter of mandril 10 is 20mm.The external quadrangle of upper mold 1 and lower die 2 is equipped with phase
Mutually matched lock 11, the lock 11 is by the lock convex block set on 1 four jiaos of upper mold and the lock groove group set on 2 four jiaos of lower die
At lock convex block and the fit clearance for latching groove are 0.3mm.
The forging mold of the present embodiment is used to forge the steering arm shaft of 8-12Kg, at this time the width in the bridge portion 8 of forging mold
Be designed as 13-15mm, then cooperate forging mold storehouse portion 9 design, draft angle α and β size, overlap be designed as 4mm(i.e. upper mold and
After lower die molding, there is the spacing of 4mm), the under-voltage amount of 0.5mm is stayed at lower die cushion faces, and mould utilization factor may be implemented and reach
It is optimal, die life is long, the teeth portion of steering arm shaft easily forges.It equally, can be right when the weight for processing steering arm shaft changes
The size of storehouse portion 9, bridge portion 8, draft angle, overlap etc. should be adjusted.
Use process is as follows: bar is put into 2 type chamber of lower die after base, upper mold 1 is fallen, and molding, bar fills when production
Full type chamber, extra bar are stored in storehouse portion 9 by bridge portion 8, after workpiece shaping, open upper mold 1, are ejected workpiece by mandril 10.
The forging mold of the utility model, type chamber are predominantly located in lower die, and using the design of vertical forging, be just easy at
During type, the bar after base can be easy full of drag chamber, and upper model cavity is because of mold to the same of bar downward pressure
When, the reaction force of bar is upward, upper mold cavity filling is expired, at this time, it may be necessary to equipment hitting power will be small, therefore mold longevity
Life length, utilization rate are high.Meanwhile die joint is set to teeth portion type chamber middle position, convenient for forming the teeth portion of steering arm shaft.In addition, adopting
With the forging mold of the utility model forge come steering arm shaft trimming after burr to be easy excision clean.
When generalling use upset forging die tool, the piece count that can be forged is 900 or so, and the vertical forging of the utility model is forged
The piece count of mold processing is up to 1200-1300 part, and the service life improves about 50%, therefore, using the steering arm of the utility model
The vertical forging forging mold of axis has very big advantage.
