Abstract
The utility model discloses a trimming die for a shifting fork with high-accuracy guiding. The trimming die comprises an upper fixing plate and a female mold. The lower end of the upper fixing plate is fixedly provided with a shifting fork outline-shaped punching head. A shifting fork outline-shaped mold cavity is arranged in the female mold. The shifting fork outline-shaped mold cavity corresponds to the punching head. A discharging port is arranged below the shifting fork outline-shaped mold cavity. The diameter of the discharging port is larger than the diameter of the shifting fork outline-shaped mold cavity. The upper end of the upper fixing plate is fixedly arranged on an upper plate. The lower end of the female mold is fixedly arranged on a lower plate. Guide pillars matched with guide covers are respectively arranged between the upper plate and the lower plate. The punching head is matched with the mold cavity after the trimming die is hot forged, and therefore the galling at the edge of the trimming fork can be removed thoroughly. The trimming die has the advantages of being high in trimming efficiency and low in cost.
Description
Technical field
The utility model relates to a kind of edger of high accuracy guiding shift fork.
Background technology
Shift fork in the machinery generally is divided into the shift fork claw, declutch shift shaft and shift fork handle set.Mainly be to stir shifting slide gear, change its position on gear shaft, can move up and down or move left and right, thereby realize different speed.Or be the control of clutch in the engineering goods, such as the structure of end face in conjunction with tooth, the structure of interior external tooth all needs to realize combination and separate with its part of fork controls.The common hot-forging forming of shift fork is processed, and edge has burr, then passes through the stamping-out moulding.
The utility model content
The purpose of this utility model provides a kind of edger of high accuracy guiding shift fork, after processing through forge hot, utilizes drift to cooperate with die cavity, thoroughly removes the burr at shift fork edge, and side cut efficient is high, and processing cost is low.
The technical solution of the utility model is as follows:
A kind of edger of high accuracy guiding shift fork, include upper mounted plate, former, the lower end of upper mounted plate is installed with the circumvallate drift of shift fork, have shift fork profile shape die cavity in the former, shift fork profile shape die cavity is corresponding with drift, the below of shift fork profile shape die cavity has Lou material mouth, leaks the diameter of material mouth greater than shift fork profile shape die cavity diameter; The upper end of upper mounted plate is fixedly installed in cope match-plate pattern, and the lower end of former is fixedly installed in lower bolster, is separately installed with the guide pillar, the guide pin bushing that cooperatively interact between cope match-plate pattern and the lower bolster.
Have installing hole on the described upper mounted plate, drift is fixedly tied in the installing hole.
The utility model utilizes drift to cooperate with die cavity after processing through forge hot, thoroughly removes the burr at shift fork edge, and side cut efficient is high, and processing cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of edger of high accuracy guiding shift fork, include upper mounted plate 1, former 2, the lower end of upper mounted plate 1 is installed with the circumvallate drift 3 of shift fork, has shift fork profile shape die cavity 4 in the former 2, and shift fork profile shape die cavity 4 is corresponding with drift 3, the below of shift fork profile shape die cavity 4 has Lou material mouth 5, leak the diameter of material mouth 5 greater than shift fork profile shape die cavity diameter, have installing hole 6 on the upper mounted plate 1, drift 3 is fixedly tied in the installing hole 6; The upper end of upper mounted plate 1 is fixedly installed in cope match-plate pattern 7, and the lower end of former 2 is fixedly installed in lower bolster 8, is separately installed with the guide pillar 9, the guide pin bushing 10 that cooperatively interact between cope match-plate pattern 7 and the lower bolster 8.
