Abstract
The utility model discloses a kind of safe liftout attachment, comprise overcoat, also comprise the ejector sleeve be slidably matched with sleeve pipe one end of described overcoat, the inner sleeve matched with the other end of the sleeve pipe of described overcoat, be arranged at described inner sleeve sleeve pipe in thimble, and being snug fit at described inner sleeve one end for promoting the cushion block of described thimble motion, described cushion block is arranged at the top of described ejector sleeve and coordinates with the cannula slide of described overcoat.The setting of cushion block can make thimble along the sleeve movement of inner sleeve by the thrust of ejector sleeve, and effectively shortens thimble length, makes to eject reliable and stable.The utility model structure is simple, and ejecting safe and reliable and thimble should not fracture.
Description
Technical field
The utility model relates to cold upsetting die of car field, particularly relates to a kind of safe liftout attachment.
Background technology
At present, liftout attachment traditional in cold upsetting die of car structure is a single thimble, and namely a thimble is directly filled in main core rod cushion block hole, and afterbody directly cruelly leaks and directly contacts with cold headers ejecting device outside.Adopt said method, mainly there is following shortcoming: 1, the long sudden and violent leakage of thimble length part outside easily fractures 2 too much, thimble is meticulous easily fractures 3, the stressed excessive thimble that easily fractures of thimble has fractureed several factors, traditional liftout attachment is a single thimble, when bolt machine non-ejecting product, thimble has most cruelly to leak outside, once bolt machine ejecting product, the stressed meeting of thimble bends, degree of crook and product eject required power, thimble diameter, thimble material, thimble length, the factors such as ejection stroke are closely related, once degree of crook is excessive, will fracture.
Utility model content
It is simple that the purpose of this utility model there are provided a kind of structure, ejects the safe liftout attachment that safe and reliable and thimble should not fracture.
For reaching this object, the utility model by the following technical solutions:
A kind of safe liftout attachment, comprise overcoat, also comprise the ejector sleeve be slidably matched with sleeve pipe one end of described overcoat, the inner sleeve matched with the other end of the sleeve pipe of described overcoat, be arranged at described inner sleeve sleeve pipe in thimble, and being snug fit at described inner sleeve one end for promoting the cushion block of described thimble motion, described cushion block is arranged at the top of described ejector sleeve and coordinates with the cannula slide of described overcoat.
Wherein, radially on the outer circumference surface of described inner sleeve the elongated slot being provided with and connecting with the sleeve pipe of described inner sleeve is run through.
Wherein, the outer circumference surface of one end of described inner sleeve sets to the concave fluted, the outer circumference surface of the inner sleeve of described groove side is axially provided with chute.
Wherein, described cushion block is that C font is arranged and middle part is provided with and ejects arm for what promote the end motion of described thimble one, described in eject arm and to match with described elongated slot and along described inner sleeve axially-movable.
Wherein, described in eject arm both sides arc inner wall on be convexly equipped with slide block, described slide block matches with described chute.
Wherein, the T-shaped and either flush of top and described overcoat of the shaft section of described inner sleeve.
Wherein, described inner sleeve and described overcoat matched in clearance.
The beneficial effects of the utility model: the utility model comprises overcoat, also comprise the ejector sleeve be slidably matched with sleeve pipe one end of described overcoat, the inner sleeve matched with the other end of the sleeve pipe of described overcoat, be arranged at described inner sleeve sleeve pipe in thimble, and being snug fit at described inner sleeve one end for promoting the cushion block of described thimble motion, described cushion block is arranged at the top of described ejector sleeve and coordinates with the cannula slide of described overcoat.The setting of cushion block can make thimble along the sleeve movement of inner sleeve by the thrust of ejector sleeve, and effectively shortens thimble length, makes to eject reliable and stable.The utility model structure is simple, and ejecting safe and reliable and thimble should not fracture.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of safe liftout attachment of the utility model.
Fig. 2 is the sectional view in AA cross section in Fig. 1.
In figure: 1. thimble, 2. inner sleeve, 21. elongated slots, 22. grooves, 3. overcoat, 4. cushion block, 41. eject arm, 42. slide blocks, 5. ejector sleeve.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing
As depicted in figs. 1 and 2, a kind of safe liftout attachment, comprise overcoat 3, also comprise the ejector sleeve 5 be slidably matched with sleeve pipe one end of overcoat 3, the inner sleeve 2 matched with the other end of the sleeve pipe of overcoat 3, be arranged at the thimble 1 in the sleeve pipe of inner sleeve 2, and be snug fit at the cushion block 4 moved for promoting thimble 1 inner sleeve 2 one end, cushion block 4 is arranged at the top of ejector sleeve 5 and coordinates with the cannula slide of overcoat 3, one end of inner sleeve is sheathed in the sleeve pipe of ejector sleeve, and radial direction runs through the elongated slot 21 being provided with and connecting with the sleeve pipe of inner sleeve 2 on the outer circumference surface of inner sleeve 2, the outer circumference surface of one end of inner sleeve 2 sets to the concave fluted 22, the outer circumference surface of the inner sleeve 2 of groove 22 side is axially provided with chute, cushion block 4 is arranged in C font and middle part is provided with and ejects arm 41 for what promote thimble 1 one end motion, eject arm 41 to match with elongated slot 21 and along inner sleeve 2 axially-movable.The arc inner wall ejecting arm 41 both sides is convexly equipped with slide block 42, and slide block 42 matches with chute.This vibrational power flow, the one end that is slidably located in the C font cushion block 4 ejecting arm 41 is arranged reeded in put, and along the runner movement of inner sleeve both sides, and then under the thrust of overcoat, promote thimble motion, shorten thimble length with this, make sliding stability reliable and should not fracture.
T-shaped and the either flush of top and described overcoat 3 of the shaft section of described inner sleeve 2.
Described inner sleeve 2 and described overcoat 3 matched in clearance.This vibrational power flow, makes the sidewall of cushion block can slide in the gap between inner sleeve and outer tube.And then make cushion block stable and reliable operation and uniform force.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
