Technical Field
The utility model belongs to the technical field of outer sizing mould, concretely relates to external diameter forming die for steel pipe.
Background
In a seamless steel pipe processing line, the quality of the end of the steel pipe directly affects the production and use, and therefore, an end sizer is used in the process. The pipe end sizing mill is equipment for sizing the pipe end of a steel pipe to enable the pipe end of the steel pipe to generate plastic deformation, improve the ovality and the straightness of the pipe end of the steel pipe and ensure the subsequent processing yield of the steel pipe, generally comprises a closing-in die, an outer sizing die and an inner sizing die, and correspondingly needs three dies, namely the closing-in die, the outer sizing die and the inner sizing die, and the design mainly relates to the outer sizing die. In order to size the outer diameter of the pipe end, the steel pipe needs to be moved and fixed to a specific position, then an outer sizing die is driven by a hydraulic cylinder to stretch into the end of the steel pipe, the end is extruded, and the outer diameter of the light pipe is improved after the end is subjected to certain plastic deformation.
However, most of the existing external sizing dies are single, so that different dies are inconvenient to replace according to different steel pipe specifications, and the frequency of die loss and the inconvenience of replacement are caused. To this end we propose an outside diameter forming die for steel pipes.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an external diameter forming die for steel pipe to it is all single to provide the outer sizing mould that has most now in solving above-mentioned background art, and different moulds are changed to inconvenient steel pipe specification according to the difference, has resulted in the frequency of mould loss and the inconvenient problem of change.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an external diameter forming die for steel pipe, includes outer sizing die holder, the inside difference fixed mounting of outer sizing die holder has dismantlement board, position sleeve and outer sizing die, the dismantlement board is located the right side of position sleeve, the position sleeve is located the left side of outer sizing die.
Preferably, locking nuts are in threaded connection between the disassembling plate, the positioning sleeve and the outer sizing die and between the disassembling plate, the positioning sleeve and the outer sizing die seat.
Preferably, one end of the outer sizing die seat is of a barrel-shaped structure, and the inner diameter of the outer sizing die is smaller than the outer diameter of the steel pipe.
Preferably, one surface of the disassembling plate contacts the positioning sleeve, and the other surface of the disassembling plate contacts the outer sizing die.
Preferably, the outer sizing die is used for sizing the outer diameter of the steel pipe, and the positioning sleeve is used for reducing the length of the die and positioning the steel pipe in the axial direction.
Preferably, one side of the disassembling plate is provided with a disassembling hole, and the outer sizing die seat, the disassembling plate, the positioning sleeve and the outer sizing die are made of the same material.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model can reduce the types of the moulds, the diameter of the steel pipe which can be adapted by the same mould is larger, and the material of the high-quality mould is reduced, thereby reducing the production cost; when the die needs to be replaced, only one of the dies needs to be replaced, so that the die is convenient and quick, and the working efficiency is improved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1. an outer sizing die holder; 2. disassembling the plate; 3. a positioning sleeve; 4. an outer sizing die; 5. and locking the nut.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides an external diameter forming die for steel pipe, includes outer sizing die holder 1, and the inside of outer sizing die holder 1 is fixed mounting respectively has stripper plate 2, position sleeve 3 and outer sizing die 4, and stripper plate 2 is located the right side of position sleeve 3, and position sleeve 3 is located the left side of outer sizing die 4.
Furthermore, a locking nut 5 is in threaded connection between the dismounting plate 2, the positioning sleeve 3, the outer sizing die 4 and the outer sizing die seat 1, so that the dismounting plate 2, the positioning sleeve 3 and the outer sizing die 4 are locked in the outer sizing die seat 1.
Furthermore, one end of the outer sizing die seat 1 is of a barrel-shaped structure, the disassembling plate 2, the positioning sleeve 3 and the outer sizing die 4 are conveniently and sequentially arranged, and the inner diameter of the outer sizing die 4 is smaller than the outer diameter of the steel pipe.
Further, one surface of the disassembling plate 2 contacts the positioning sleeve 3, and the other surface of the disassembling plate 2 contacts the outer sizing die 4, so that the outer sizing die 4 can be disassembled when the specification is changed.
Further, the outer sizing die 4 is used for sizing the outer diameter of the steel pipe, and the positioning sleeve 3 is used for reducing the length of the die and positioning in the axial direction.
Furthermore, a dismounting hole is formed in one side of the dismounting plate 2, the outer sizing die 4 and the positioning sleeve 3 are dismounted together through the dismounting hole in the dismounting plate 2, the replacing process is completed, and the outer sizing die seat 1, the dismounting plate 2, the positioning sleeve 3 and the outer sizing die 4 are made of the same material.
The utility model discloses a theory of operation and use flow:
one end of the outer sizing die seat 1 is installed on the sizing mill body, the other end of the outer sizing die seat is of a barrel-shaped structure, the dismounting plate 2, the positioning sleeve 3 and the outer sizing die 4 can be sequentially installed, and finally the dismounting plate 2, the positioning sleeve 3 and the outer sizing die 4 are locked in the outer sizing die seat 1 through the locking nut 5. During sizing, the steel pipe is fixed and locked, the outer sizing die holder 1 is close to the steel pipe under the drive of the hydraulic cylinder, so that the end part of the steel pipe passes through the locking nut 5 and then enters the outer sizing die through the guide groove of the outer sizing die 4, the inner diameter of the outer sizing die 4 is smaller than the outer diameter of the steel pipe, the outer diameter of the steel pipe generates extrusion force, the end part of the steel pipe generates shaping deformation, and the outer sizing effect is achieved. And after the external sizing length is reached, the external sizing die 4 retreats to complete the whole external sizing process. When the die needs to be replaced, the outer sizing die 4 and the positioning sleeve 3 are detached together through the detaching holes in the detaching plate 2, and the replacing process is completed.
