Abstract
The utility model discloses a trimming die for a shifting fork. The trimming die comprises an upper fixed plate and a female die, wherein a punch in a shape of the outline of the shifting fork is fixedly arranged at the lower end of the upper fixed plate; a cavity in the shape of the outline of the shifting fork is formed in the female die and corresponds to the punch; a leaking hole is formed on the lower side of the cavity in the shape of the outline of the shifting fork; and the diameter of the leaking hole is greater than that of the cavity in the shape of the outline of the shifting fork. After the trimming die is subjected to hot forging treatment, burrs on the edge of the shifting fork can be thoroughly removed by matching the punch with the cavity; and the trimming die is high in trimming efficiency and low in machining cost.
Description
Technical field
The utility model relates to a kind of edger that is used for 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 combination tooth, the structure of interior external tooth all need realize combining and separating with its part of fork controls.The common hot-forging forming of shift fork is handled, and edge has burr, passes through the stamping-out moulding then.
The utility model content
The purpose of the utility model provides a kind of edger that is used for shift fork, after handling 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 scheme of the utility model is following:
A kind of edger that is used for shift fork; Include upper mounted plate, former; The lower end of upper mounted plate is installed with the circumvallate drift of shift fork, has shift fork profile shape die cavity in the former, and shift fork profile shape die cavity is corresponding with drift; The below of shift fork profile shape die cavity has Lou material mouth, and the diameter that leaks the material mouth is greater than shift fork profile shape die cavity diameter.
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 handling 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 the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, a kind of edger that is used for shift fork includes 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; The diameter that leaks material mouth 5 has installing hole 6 greater than shift fork profile shape die cavity diameter on the upper mounted plate 1, drift 3 is fixedly tied in the installing hole 6.
Claims (2)
1. edger that is used for shift fork; Include upper mounted plate, former; It is characterized in that: the lower end of upper mounted plate is installed with the circumvallate drift of shift fork, has shift fork profile shape die cavity in the former, and shift fork profile shape die cavity is corresponding with drift; The below of shift fork profile shape die cavity has Lou material mouth, and the diameter that leaks the material mouth is greater than shift fork profile shape die cavity diameter.
2. the edger that is used for shift fork according to claim 1 is characterized in that: have installing hole on the described upper mounted plate, drift is fixedly tied in the installing hole.
