Description
Technical field
The utility model is related to slip shaft yoke fields, and in particular to a kind of slip shaft yoke base mould forced locking device.
Background technology
Slip shaft yoke forging usually with after intermediate frequency heating in hot forging using jumping-up or directly carry out horizontal rough forge and
Finish forge traditional handicraft is forged.Because bar diameter carries out blanking by slip shaft yoke fork diameter, slip shaft yoke fork diameter is remote
Much larger than shank diameter, the direct base of bar cannot be caused to forge the more overlap of rear shank generation in hot forging equipment.?
Utilization rate is relatively low in the use of material, causes the waste of material, it is therefore desirable to a kind of novel to be designed to deal with existing design
In deficiency.
Utility model content
The utility model solves above-mentioned deficiency in the prior art, provides a kind of slip shaft yoke base mould auto lock dress
It sets, the utility model is directed to heavy duty transmission axis slip shaft yoke usually because of the feature that fork diameter is big, shank diameter is small, in hot forging
Increase forced locking device on equipment mould bases, different blanking molds is manufactured and designed according to different slip shaft yokes, by base mould
Tool is mounted in forced locking device, by carrying out blocking again after bar base, it is therefore an objective to reduce heavy duty transmission slip shaft yoke
Shank overlap improves stock utilization.
Technical solution adopted by the utility model to solve its technical problems is：This slip shaft yoke base mould auto lock
Device, the device include top mold frame and lower mold holder, and top mold frame is equipped with upsetting apparatus；Lower mold holder is equipped with base die clamp and tightly fills
It sets.
The upsetting apparatus is formed by connecting by top mold frame, screw rod and regulating nut；The top mold frame and inside screw
Through there is mould bases connecting screw hole, mould bases connecting screw is installed inside mould bases connecting screw hole, mould bases connecting screw bottom connects spiral shell
Cap；Screw rod bottom connects regulating nut.
Locking screw rod aperture is provided with inside regulating nut on the upsetting apparatus.
The base mould clamping device is connected in sequence by cylinder A, cylinder jacket, jumping-up seat main body and cylinder B.
The lower mold holder is laterally provided with open slot.
The utility model has the beneficial effects that：The utility model realizes heavy duty transmission axis slip shaft yoke bar length
The base forming of the product of height, effectively improves stock utilization between mold and equipment top dead-centre.Realize blanking device bar
It is put into automatic unlocking function after rear auto lock, forming, mitigates staff labor intensity significantly.Improve heavy slip shaft yoke material profit
With rate 10%, the tonnage that material is saved for centering large enterprise will be in terms of hundred tons.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in the figure：A kind of slip shaft yoke base mould forced locking device, the device include upper mold 1 and lower die 2, upper mold 1
Top mold frame 3 upsetting apparatus 4 is installed；The lower mold holder 5 of lower die 2 is equipped with base mould clamping device 6.The upsetting apparatus 4
It is formed by connecting by top mold frame 3, screw rod 7 and regulating nut 8；The top mold frame 3 and 7 inside of screw rod, which runs through, mould bases connecting screw hole
9, mould bases connecting screw 10,10 bottom coupling nut 11 of mould bases connecting screw are installed inside mould bases connecting screw hole 9；7 bottom of screw rod
Portion connects regulating nut 8.It is provided with locking screw rod aperture 12 inside regulating nut 8 on the upsetting apparatus 4.The base mould
Clamping device 6 is connected in sequence by cylinder A 13, cylinder jacket 14, jumping-up seat main body 15 and cylinder B 16.The lower mold holder 5
Laterally it is provided with open slot 17.
Specific technological process is (such as Fig. 5)：
1. according to each product slip shaft yoke fork and shank diameter, fork and shank length analysis, according to shank diameter
Shank diameter and weight are determined with length, and upset diameter and length are determined according to fork diameter and length, it is straight according to fork jumping-up
Diameter and length gauge calculate fork weight, finally determine 18 diameter of bar, length and weight, design different product base mould (Fig. 2).
2. the length of upsetting apparatus 4 is adjusted using regulating nut 8 according to the length of bar 18.
3. base mould clamping device 6 electric control system be taken in heating bar 18 from side to open slot 17 be put into system
Locking is automatically closed with cylinder B 16 after bar placement location 22 in mold clamping device 6, when equipment operation base rear slider
When returning to top dead-centre, 6 automatic unlocking of base mould clamping device unclamps, and is then fetched into blocking station from side to by base material 19,
To realize cycle auto lock base.
Such as Fig. 7, the slip shaft yoke manufacturing process in existing design be slip shaft yoke forging 20 usually with intermediate frequency heating after
Jumping-up is used in hot forging or directly carries out horizontal rough forge and the forging of finish forge traditional handicraft.Because 18 diameter of bar presses slip shaft yoke
Fork diameter carries out blanking, and slip shaft yoke fork diameter is far longer than shank diameter, cannot be to stick in hot forging equipment
Expect direct base, causes to forge rear shank and plug generates more overlap 21.
Such as Fig. 6, the utility model on the basis of existing design by increasing base mould clamping device 6, entire technique
Bar 18 is first upset as suitable blank 19 in flow, then blank 19 is put into blocking station to become forging 20, flying at this time
Side 21 is only generated in plug part, therefore is also avoided shank while saving material and led to the problem of overlap.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
