Have it is easy for construction, there is higher compressive property and preferable corrosion resistance, anti-wear performance, substantially instead of other pipes
Material.
At present, for centrifugal ductile cast iron pipes in casting process, cast tube tube drawing process has two ways, ejector sleeve and tube drawing, passes
System tube drawing pliers use three-jaw, clamp block alloy-free head, and during tube drawing, because of three-jaw unbalance stress, body local deformation is larger, and
Tube drawing is relatively difficult, often occurs cast tube being split up, and causes waste product, or often de- pincers repeatedly disengaging, pulls out not outlet pipe and come, cause to give birth to
It is low to produce efficiency, has a strong impact on centrifuge whole efficiency.
The content of the invention
In order to solve the deficiencies in the prior art, solve cast tube and be split up, take off pincers, pull out the technical problem that outlet pipe is not come,
The utility model provides a kind of simple in construction, in light weight, tube drawing success rate height, low manufacture cost, service life length and maintenance side
Just tube drawing pliers.
The utility model is achieved by the following technical programs.
A kind of tube drawing pliers, it includes pincers core, wherein：
Pincers core front end is fixedly installed with externally threaded joint, and binding clip is cooperatively provided with joint external screw thread, is clamped
Circumferentially direction is provided with outside radial unlimited guide plate to tail end；
Pincers core rear end is fixedly installed jacking block, and the head band of the jacking block is tapered, and top and the pincers core rear end of jacking block are consolidated
Fixed connection, jacking block bottom is provided with internal thread, is cooperatively provided with push rod with internal thread, the push rod other end passes through connecting bushing
It is connected with PTO；Fixed body is provided with the middle part of push rod, fixed body one end is provided with sleeve pipe, and sleeve pipe rear end is provided with card
Disk, fixed body are fixedly connected by chuck with the external world, guide copper sleeve are provided between chuck and push rod, sleeve outer wall is removably
Pressing plate is provided with, gap is provided between pressing plate and sleeve outer wall；
Circumferentially direction is evenly equipped with some pieces of pincers blocks that can be opened or close up in outside in the middle part of pincers core, clamps outside the head of block
Side is engaged with the medial surface of the guide plate, and pincers block tail inner side face is engaged with jacking block lateral surface；Clamp lateral wall in the middle part of block
Be provided with sealing ring, pincers block outer wall afterbody is fixedly installed distending plate, the distending plate other end be connected in pressing plate and sleeve outer wall it
Between gap in, the material of the distending plate is spring steel.
Further, the material of the pincers block is 42CrMo.
The utility model has the advantages that compared with prior art.
A kind of tube drawing pliers provided by the utility model, material selection are proper：Pincers block is made using 42CrMo steel, there is high intensity
And toughness, quenching degree is also preferable, without obvious temper brittleness, there is higher fatigue limit and anti-repeat impact energy after modifier treatment
Power；During use, pincers core pushing tow pincers block when institute is constrained less, pincers wick feed pincers block component very little, when tube drawing pliers shrink, pulls out
Pipe wrench top guide block helps to clamp the contraction of block fast uniform, and tube drawing pliers are not easy stuck and service life and grown when working；Due to structure
It is simple light, change specification and be also convenient for.
Brief description of the drawings
Fig. 1 is the utility model overall structure sectional view.
Embodiment
The utility model is elaborated with reference to embodiment：The present embodiment be using technical solutions of the utility model as
Premise is implemented, and gives detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In the following examples.
As shown in figure 1, a kind of tube drawing pliers, it includes pincers core 2, wherein：
Pincers core 2 front end is fixedly installed with externally threaded joint 21, and pincers are cooperatively provided with the external screw thread of joint 21
First 1, circumferentially direction is provided with outside radial unlimited guide plate to the tail end of binding clip 1；
Pincers core 2 rear end is fixedly installed jacking block 22, and the head band of the jacking block 22 is tapered, top and the pincers core of jacking block 22
2 rear ends are fixedly connected, and the bottom of jacking block 22 is provided with internal thread, and push rod 5, the other end of push rod 5 are cooperatively provided with internal thread
It is connected by connecting bushing 9 with PTO；The middle part of push rod 5 is provided with fixed body 7, and the one end of fixed body 7 is provided with sleeve pipe
71, the rear end of sleeve pipe 71 is provided with chuck 72, and fixed body 7 is fixedly connected by chuck 72 with the external world, is set between chuck 72 and push rod 5
