Technical field
The present invention relates to forging equipment technical fields, specifically provide a kind of motor copper piece end ring cold drawn section mold.
Background technique
Currently, motor copper piece end ring product cold deformation generallys use pneumatic hammer cold forging, which is difficult to realize the essence of size
Therefore quasi- control internal-and external diameter and subsequent is required to biggish machining allowance is arranged that (internal-and external diameter surplus is set as 10mm, thickness
Surplus is set as 3mm or more).In addition, this kind of mode end ring material utilization rate is low, when being thumped using this kind of mode to workpiece, need
Biggish impact force is wanted, the cold forging of end ring is just able to achieve.
Therefore it provides a kind of novel equipment of cold forging, to increase stock utilization, reduce manufacturing cost, realization ruler
Very little is precisely controlled, avoids thumping energetically, becomes people's urgent problem to be solved.
Summary of the invention
In consideration of it, the purpose of the present invention is to provide a kind of end ring cold drawn section mold, to solve in a manner of existing end ring cold forging
The problems such as low accurate control for thumping, being difficult to realize size energetically, stock utilization, high production cost need to be used.
Present invention provide the technical scheme that end ring cold drawn section mold, comprising: die holder, mold core, lower die washer, lower die, under
It is molded circle, upper mold, upper mold pressing ring, liftout plate and mandril, wherein successively fixation is set from inside to outside for mold core, lower die and lower die pressing ring
It is placed in the top of die holder, lower die washer is set between mold core and lower die, and three forms workpiece rest area, and the bottom surface of upper mold is
Annular inclined surface, upper mold are fixedly connected by upper mold pressing ring with yaw driving mechanism, when upper mold is in the drive of yaw driving mechanism
When backspin switch head, the bottom surface of upper mold can the upper top surface to workpiece squeezed along its circumferential roller, mandril is more, along ejection
The circumferential direction of plate is uniformly distributed, and the lower part of mandril is fixedly connected with liftout plate, and the top of mandril is through die holder and upper top surface and lower die
The bottom surface of washer connects, and mandril can push the upward workpiece of lower die washer under the promotion of liftout plate.
It is preferred that the inclination angle of the bottom surface of upper mold is 1~5 degree.
Further preferably, a circular groove is arranged in the center of the top of die holder, the lower part setting one on the inside of mold core with
The fin of circular groove cooperation, it can be achieved that mold core and die holder coaxial placement.
Further preferably, mold core, lower die and lower die pressing ring pass through screw rod and are fixedly connected with die holder.
Further preferably, the lower part of mandril is locked after liftout plate by bolt.
Further preferably, mandril is 6.
Further preferably, upper mold, die holder and liftout plate coaxial arrangement.
End ring cold drawn section mold provided by the invention is as follows to the process of workpiece cold forging: by workpiece be placed in by mold core, under
The workpiece rest area that die-cushion circle and lower die are formed, later, whereabouts upper mold controls its rotation after upper mold, which is fallen to, to offset with mold core
Switch head, the bottom surface for being obliquely installed it squeeze workpiece along the circumferential roller of workpiece, meanwhile, control liftout plate is transported upwards
It is dynamic, and then mandril and lower die washer is driven to move up, at this point, workpiece will generate under upper mold and the collective effect power of lower die washer
Deformation terminates cold forging after being deformed into full of workpiece rest area.
End ring cold drawn section mold provided by the invention, it is structurally reasonable, direct opposite-compacting type cold forging is compared, is with lesser pressure
It can reach previous cold forging effect, improve stock utilization, reduce manufacturing cost, realize the accurate control of size
System.
Detailed description of the invention
With reference to the accompanying drawing and embodiment the present invention is described in further detail:
Fig. 1 is the structural schematic diagram of end ring cold drawn section mold provided by the invention；
Fig. 2 is the working state schematic representation of end ring cold drawn section mold provided by the invention.
Specific embodiment
The present invention is further explained below in conjunction with specific embodiment, but the not limitation present invention.
As shown in Figure 1 and Figure 2, the present invention provides a kind of end ring cold drawn section molds, comprising: die holder 1, mold core 2, lower die-cushion
Circle 3, lower die 4, lower die pressing ring 5, upper mold 6, upper mold pressing ring 7, liftout plate 8 and mandril 9, wherein mold core 2, lower die 4 and lower die pressing ring
5 are successively fixedly installed on the top of die holder 1 from inside to outside, and lower die washer 3 is set between mold core 2 and lower die 4, and three forms work
Part rest area, the bottom surface of upper mold 6 are annular inclined surface, it is preferable that the inclination angle of the bottom surface of upper mold 6 is 1~5 degree, and upper mold 6 passes through
Upper mold pressing ring 7 is fixedly connected with yaw driving mechanism, when drive backspin switch head of the upper mold 6 in yaw driving mechanism, upper mold 6
