Abstract
The utility model discloses a fracture mould for steel pipe, including the axis, the cover has the floating axle on one end of the axis, is equipped with the shaft shoulder on the other end, and the broken mould that sets up on the shaft shoulder links together with the shaft shoulder through the mode of pegging graft, the broken mould constitutes the ring coaxial with the axis jointly, and the ring center that constitutes jointly by the broken mould is equipped with wedge circular slot mouth, the interior shape of circular slot mouth sets up the expansion block; the end cover cup joints on the ring of constituteing jointly by disconnected mould, the end cover sets up in one side of ring, the utility model has the advantages that: shearing force on the pipe parts is formed in the pipe, so that shearing force cuts the fracture from the inside of the pipe, and the floating shaft is matched with the die to be suitable for pipe structures with different inner diameters.
Description
Technical Field
The utility model relates to a machine adds the field, a port shearing mechanism of bellows specifically says so.
Background
The end parts of some pipe parts have special-shaped structures, the inner parts of the pipe parts are smooth, if the pipe parts are subjected to wire cutting only from the outside or are processed by a lathe or other machining methods, the phenomenon of extrusion deformation of the end parts is caused, in addition, the phenomenon of long processing time is caused, and the best mode for processing the fracture is to generate a shearing force on the end parts.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a port shearing mechanism of bellows.
The specific technical scheme is as follows:
a fracture mould for a steel pipe comprises a middle shaft, wherein a floating shaft is sleeved at one end of the middle shaft, a shaft shoulder is arranged at the other end of the middle shaft, broken dies arranged on the shaft shoulder are connected with the shaft shoulder in an inserting mode, the broken dies jointly form a circular ring coaxial with the middle shaft, a wedge-shaped circular notch is formed in the center of the circular ring jointly formed by the broken dies, and an expansion block is arranged in the circular notch in a shape following mode; the end cover is covered on a circular ring formed by the broken dies together, and the end cover is arranged on one side of the circular ring.
The floating shaft is arranged corresponding to the die-breaking size, and the diameter of a circular ring formed by the outer diameter of the floating shaft and the die-breaking is matched with the inner diameter of different steel pipes.
The floating shaft and a circular ring formed by the broken molds are coaxially arranged.
The utility model has the advantages that: shearing force on the pipe parts is formed in the pipe, so that shearing force cuts the fracture from the inside of the pipe, and the floating shaft is matched with the die to be suitable for pipe structures with different inner diameters.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a left side view of fig. 1.
Detailed Description
The utility model is described in detail with reference to the accompanying drawings, as shown in fig. 1 and fig. 2, a fracture mold for steel pipes comprises a center shaft 1, a floating shaft 2 is sleeved on one end of the center shaft 1, a shaft shoulder 101 is arranged on the other end of the center shaft, a broken mold 3 arranged on the shaft shoulder is connected with the shaft shoulder 101 in a splicing manner, the broken mold 3 jointly forms a ring 4 coaxial with the center shaft, a wedge-shaped circular notch 401 is arranged at the center of the ring jointly formed by the broken molds, and an expansion block 5 is arranged in the circular notch 401 in a shape following manner; the end cover 6 is covered on the circular ring 4 formed by the broken dies together, and the end cover is arranged on one side of the circular ring.
The floating shaft 2 and the die-breaking 3 are correspondingly arranged in size, and the diameter of a circular ring formed by the outer diameter of the floating shaft and the die-breaking is matched with the inner diameter of different steel pipes.
The floating shaft 2 and a circular ring 4 formed by the broken molds are coaxially arranged.
The utility model discloses a theory of operation is: the size of the floating shaft and the size of the broken die are determined according to the pipe parts with different inner diameters, then the floating shaft and the broken die are assembled on the middle shaft, the device is placed in the pipe inner diameter, and after the device is placed, the axial force is applied to the expansion block and converted into the radial force on the pipe parts, so that the shearing function is completed.
Claims (3)
1. The utility model provides a fracture mould for steel pipe, includes axis, its characterized in that: the floating shaft is sleeved at one end of the middle shaft, the shaft shoulder is arranged at the other end of the middle shaft, the broken dies arranged on the shaft shoulder are connected with the shaft shoulder in an inserting mode, the broken dies jointly form a circular ring coaxial with the middle shaft, the center of the circular ring jointly formed by the broken dies is provided with a wedge-shaped circular groove opening, and an expansion block is arranged in the circular groove opening in a shape following mode; the end cover is covered on a circular ring formed by the broken dies together, and the end cover is arranged on one side of the circular ring.
