Description
Technical field
The present invention relates to a kind of forging mold parts, the bar Lifting Device is forged in the rotation that relates in particular to a kind of forging mold.
Background technology
It is one of vitals in the swaging mould that Lifting Device is forged in rotation.As shown in Figure 1, the Lifting Device of prior art is made up of liftout head and piston rod, and the part that the liftout head stretches into piston rod is connected with piston rod thread.When this mechanism worked, piston rod drove the liftout head and moves up and down.The liftout head can be subjected to the active force of horizontal direction when contacting with bar, can rock by occurred level, the horizontal displacement of liftout head, cause piston rod stressed, the generation type becomes, because structural design is unreasonable, often just rotate forging equipment lower main axis liftout oil cylinder piston bar internal thread and grind badly, be very easy to cause fractureing of piston rod spline pin.
Also has a kind of improved Lifting Device in the prior art; as shown in Figure 2; form by liftout head, piston rod, adapter sleeve; adapter sleeve is arranged between piston rod and the liftout head; relying on elastic type to become the frictional force that obtains between liftout head and the adapter sleeve links to each other; this device can effectively solve the problem that piston rod spline pin fractures, and has played the effect of protection liftout oil cylinder piston bar.But, being subjected to very big active force when contacting with bar owing to the liftout head, it is connected with the frictional force of adapter sleeve can't make the liftout head remain in the piston rod, through regular meeting the phenomenon that the liftout head is extracted by bar takes place.To 4000 tons of potential hazards that press equipment is bigger.Its subject matter is ejector position, the piston part intensity wretched insufficiency that rises, and easy fracture.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively solve the forging mold rotation forging Lifting Device that piston rod spline pin fracture and liftout head are deviate from.
Technical scheme of the present invention is: the rotation of forging mold is forged ejector and is made up of liftout head, trip bolt, bottom end cover, adapter sleeve, piston rod, lock pin, connecting axle, pinning, key ring, shaft block ring.The liftout head is connected with bottom end cover, and bottom end cover is connected with trip bolt with connecting axle.Connecting axle is connected with adapter sleeve.Described liftout head adopts bolt to be connected with bottom end cover, and described adapter sleeve adopts with piston rod and is threaded.Bottom end cover connects liftout head and connecting axle, adapter sleeve fixed piston rod and connecting axle, makes rotation forge ejector and is combined as a whole the problem of having prevented the liftout head to be pulled out by bar preferably.Adapter sleeve has played the effect of protection piston rod.
Described connecting axle bottom is provided with horizontal cavity, and interior placement lock pin is provided with pinning in the connecting axle internal diameter cavity, and the adapter sleeve bottom is provided with gap.Described pinning is set in the connecting axle, and the extruding lock pin makes lock pin enter adapter sleeve bottom opening position, and fixed connection shaft is in piston rod inside.The setting of lock pin and pinning has overcome the technological deficiency that " relies on the frictional force of elastic type change acquisition to link to each other " in original technology.
In bottom end cover, the top of trip bolt is provided with the key ring.The key ring has increased the field of load of trip bolt and connecting axle, makes connecting axle more fastening with being connected of bottom end cover.
Shaft block ring is set on bottom end cover.Shaft block ring makes connection liftout head be connected with the bolted of bottom end cover.
The present invention is provided with pinning, lock pin fixed connection shaft and adapter sleeve by changing the liftout header structure, preferably resolves the fastening problem of liftout head and adapter sleeve, has improved the liftout head that exists in the prior art and has been extracted a difficult problem by bar.
Description of drawings
The present invention is described further with the specific embodiment in conjunction with the accompanying drawings.
Fig. 1 is that the structural representation of Lifting Device is forged in the rotation of one of prior art forging mold
Fig. 2 is that the structural representation of Lifting Device is forged in the rotation of one of prior art forging mold
Fig. 3 is the structural representation that ejector is forged in the rotation of forging mold of the present invention
The specific embodiment
As shown in Figure 3, the rotation of forging mold of the present invention forging ejector is made up of liftout head 1, trip bolt 2, bottom end cover 3, adapter sleeve 4, piston rod 5, lock pin 6, connecting axle 7, pinning 8, key ring 9, shaft block ring 10.
Described connecting axle 7 bottoms are provided with horizontal cavity, and interior placement lock pin 6 is provided with pinning 8 in the connecting axle 7 internal diameter cavitys, and adapter sleeve 4 bottoms are provided with gap.Described pinning 8 is set in the connecting axle 7, and extruding lock pin 6 makes lock pin 6 enter adapter sleeve 4 bottom opening positions, and fixed connection shaft 7 is in piston rod 5 inside.The setting of lock pin 6 and pinning 8 has overcome the technological deficiency that " relies on the frictional force of elastic type change acquisition to link to each other " in original technology, has proposed a kind of connected mode preferably.
In bottom end cover 3, the top of trip bolt 2 is provided with key ring 9.Key ring 9 has increased the field of load of trip bolt 2 with connecting axle 7, makes connecting axle 7 more fastening with being connected of bottom end cover 3.
The assembling sequence that ejector is forged in the rotation of forging mold of the present invention is: earlier lock pin 6 is put into connecting axle 7, again connecting axle 7 is put into adapter sleeve 4, pinning 8 is put into connecting axle 7.Connect bottom end cover 3 and connecting axle 7 with trip bolt 2.Connect bottom end cover 3 and liftout head 1 with bolt at last.
The duty of ejector is forged in the rotation of forging mold of the present invention, and when piston rod 5 moved upward, adapter sleeve 4, lock pin 6, connecting axle 7, trip bolt 2, bottom end cover 3, liftout head 1 was stressed successively moves upward, with bar jack-up.When piston rod 5 moves downward, adapter sleeve 4, lock pin 6, connecting axle 7, trip bolt 2, bottom end cover 3, stressed successively stressed successively the moving downward that move upward of liftout head 1.
The piston rod 5 that the rotation forging ejector of forging mold of the present invention provides and the connected mode of liftout head 1; be not limited to the described content of the content of the present invention and the specific embodiment; content inspires and other connected modes of acquisition according to the present invention, all falls into protection scope of the present invention.
