Abstract
The utility model relates to the field of a mandrel structure of a coiling machine. The mandrel structure comprises a mandrel body, wherein the mandrel body comprises a coiling section and a supporting section as well as a transition section, the transition section is located between the coiling section and the supporting section and at least comprises a first transition step and a second transition step, the first transition step and the coiling section are integrated through connecting, and one end of the second transition step and the supporting section are integrated through connecting. According to the mandrel structure of the coiling machine, mandrels with two different coiling diameter specification sizes can be mounted on the same speed reduction box.
Description
Technical field
The utility model relates to the coiling machine in hot rolling or the cold rolling steel process, particularly a kind of coiling machine mandrel structure.
Background technology
Existing coiling machine mandrel, formed by the supporting section that reduction-gear housing can be used to batch the section of batching of coil of strip internal diameter φ 508 outward and utilizes bearing to support in reduction-gear housing, the mandrel of coil of strip internal diameter φ 508 can be installed in the reduction-gear housing of φ 508 coil diameters, because coil diameter is little, the external diameter of supporting section of mandrel that is fit to batch coil of strip internal diameter φ 508 is less with the vary in diameter of the supporting section that utilizes bearing to support, dangerouse cross-section meets design requirement, so reduction box can only be installed the mandrel of φ 508 rouleaus footpath specification.One case, design cannot be installed the mandrel of two kinds of coil diameter specifications that vary in size for same reduction box separately.
Summary of the invention
At the deficiencies in the prior art, the utility model has related to a kind of coiling machine mandrel structure, and the mandrel of two kinds of coil diameter specifications that vary in size can be installed for same reduction box.
The utility model is achieved through the following technical solutions:
Coiling machine mandrel structure, comprise the mandrel body, the mandrel body comprises the section of batching and supporting section, the mandrel body also comprises a changeover portion, this changeover portion is between the section of batching and supporting section, changeover portion comprises first transition shoulder and second transition shoulder at least, and first transition shoulder connects as one with the section of batching, and an end and the supporting section of second transition shoulder connect as one.
Further, the external diameter of first transition shoulder is less than the external diameter of the section of batching, and the external diameter of first transition shoulder is greater than the external diameter of second transition shoulder, and the external diameter of second transition shoulder is greater than the external diameter of supporting section.
Further, the external diameter of first transition shoulder is 520mm, and the external diameter of second transition shoulder is 420mm.
Further, pass through arc transition between first transition shoulder and second transition shoulder.
Adopted such scheme, the utility model is provided with multistage transition shoulder between supporting section and the section of batching, and has realized can installing for same reduction box the mandrel of two kinds of coil diameter specifications that vary in size.And can strengthen the diameter of mandrel, simultaneously, reduce the section constriction coefficient, concentrate thereby reduced stress.
Description of drawings
It is structural representation of the present utility model among Fig. 1;
Fig. 2 is the U portion enlarged drawing of Fig. 1;
Among the figure, 1 is the mandrel body, and 10 are the section of batching, and 11 is supporting section, and 12 is first transition shoulder, and 13 is second transition shoulder.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
See figures.1.and.2, coiling machine mandrel structure of the present utility model comprises mandrel body 1, and mandrel body 1 comprises the section of batching 10 and supporting section 11.The mandrel body also comprises a changeover portion, this changeover portion is between the section of batching and supporting section, changeover portion comprises that at least first transition shoulder 12 and second transition shoulder, 13, the first transition shoulders 12 connect as one with the section of batching 10, and an end and the supporting section of second transition shoulder 13 connect as one.The external diameter of first transition shoulder 12 is less than the external diameter of the section of batching 10, and the external diameter of first transition shoulder 12 is greater than the external diameter of second transition shoulder 13, and the external diameter of second transition shoulder 13 is greater than the external diameter of supporting section 11.The external diameter of first transition shoulder is 520mm, and the external diameter of second transition shoulder is 420mm.Pass through arc transition between first transition shoulder 12 and second transition shoulder 13.
The utility model is when manufacturing is batched the coil of strip internal diameter and is the mandrel of φ 760, it is the shaft shoulder place of on the physical dimension of φ 508 mandrels spring bearing being installed with the coil of strip internal diameter, progressively strengthen towards a plurality of step surfaces of external support direction diameter dimension segmentation vertically, as be increased to and be fit to batch the mandrel that the coil of strip internal diameter is φ 760, adopted two step surfaces; And the diameter of axle that remains in the reduction box is constant, and in shaft shoulder place arc transition.Precondition is when batching internal diameter and being the load of φ 760 coil of strips, and dangerouse cross-section can satisfy the fatigue strength under the alternate stress.
