Abstract
The utility model relates to a tool and die for a cold-rolling pilger mill, in particular to a ring pass for the cold-rolling pilger mill. The ring pass comprises a cylindrical substrate, wherein a pass of which the radius changes from big to small, and detachable pressure plates are arranged at the two sides of the pass; a driving groove is formed inside the substrate, and a driving block is arranged in the driving groove; a driving shaft is arranged in the middle of the driving block. According to the ring pass for the cold-rolling pilger mill, a rolling part of the ring pass is configured into a replaceable part, and a connecting part is a universal part; when steel tubes with different apertures are produced, the corresponding rolling part can be replaced according to needs, so that the replacement of the connecting part is eliminated, the versatility of the parts is reserved, the utilization rate of the ring pass is improved, and the cost of tool and die is saved.
Description
Technical field
The utility model relates to the tool and mould on a kind of cold-rolling pilger mill, especially a kind of cold-rolling pilger mill annular distance type.
Background technology
Cold-rolling pilger mill is the machinery equipment that steel pipe is rolled to distortion, its reciprocating motion by annular distance type is rolled distortion to steel pipe, at present, annular distance type on two-high cold-rolling pipe mill has the pass of a descending variation of radius on its circumference, is that pipe is rolled at conic mandrel bar with between two annular distance types that coordinate up and down.
For large-scale cold-rolling pilger mill, its annular distance molded dimension is larger, cannot process the steel pipe that caliber is less, and pass utilization rate is told somebody what one's real intentions are, and is only generally 50%, has larger waste, and tool and mould cost is very high.
Utility model content
The utility model provides a kind of raising pass utilization rate, the cold-rolling pilger mill annular distance type of saving tool and mould cost.
To achieve these goals, the utility model adopts following technical scheme:
The utility model comprises a cylindrical base, the periphery of described matrix is provided with the pass of the descending variation of Radius, and its improvement is: described pass both sides are provided with detachable pressing plate, and matrix inside is provided with driver slot, in driver slot, be provided with drive block, drive block middle part is provided with driving shaft.
Preferably, described pressing plate area equals the floor space of pass.
Preferably, described pressing plate is circular.
Preferably, between described drive block and driver slot, be provided with and drive position.
Preferably, described driving position is symmetrical arranged.
Preferably, described drive block cross section is class annular, is provided with a flat side at edge.
Preferably, flat side is along driving position symmetry axis to divide equally.
Owing to having adopted said structure, the rolling portion of the annular distance type of cold-rolling pilger mill is made as field-replaceable unit by cold-rolling pilger mill annular distance type of the present utility model, connecting portion is made as universal component, in the time producing the steel pipe of different pore size, can change as required corresponding rolling portion, the replacing of having omitted connecting portion, has retained the versatility of parts, improve the utilization rate of annular distance type, saved tool and mould cost.

Detailed description of the invention
As Figure 1-Figure 2, the cold-rolling pilger mill annular distance type of the present embodiment comprises a cylindrical base 1, the periphery of described matrix 1 is provided with the pass 2 of the descending variation of Radius, described pass 2 both sides are provided with detachable pressing plate 3, matrix 1 inside is provided with driver slot 4, in driver slot 4, be provided with drive block 5, drive block 5 middle parts are provided with driving shaft 6.
Concrete, in the present embodiment, in order to keep changing the uniformity of part and fixture, described pressing plate area equals the floor space of pass.
Because matrix is cylindrical, so in the present embodiment, described pressing plate 3 is circular.
In order to make drive block carry out good driving to matrix, between described drive block 5 and driver slot 4, be provided with and drive position 51.
For the stability of strengthening driving, described driving position 51 is symmetrical arranged.
Concrete, in the present embodiment, described drive block cross section is class annular, when installing contraposition accurate, be provided with a flat side 52 at edge, flat side 52 is along driving position symmetry axis to divide equally.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
