Description

Spool made of alloy steel

Technical Field

The utility model relates to the technical field of spool, in particular to a spool made of alloy steel.

Background

The spool is generally made of plastic material and has a specific shape and structure, so that the spool is convenient to install and operate. It generally has a hub and gear profile to which the wire can be secured by simple insertion or assembly, the shape and structural design of the spool being such that the wire can be tightly wrapped therearound to form a neat roll. The winding device can effectively limit the winding of the wire rod and prevent the wire rod from falling off and being disordered.

But traditional spool each part forms through the welding, can lead to the welding position to take place the fracture when using for a long time like this to influence work efficiency and working cost, the ring flange edge is more sharp-pointed moreover, increases crackle and cracked risk, thereby reduces the intensity and the life-span of spool.

Disclosure of Invention

Aiming at the problems, the utility model provides a spool to solve the problems of low service life and low strength of the traditional spool, and adopts the following technical scheme:

the utility model provides a spool of alloy steel material, includes the spool center pin, spool center pin top is provided with first ring flange, spool center pin bottom is provided with the second ring flange, first ring flange and second ring flange edge all have the chamfer, the spool center pin first ring flange and second ring flange material are alloy steel material, the spool center pin first ring flange and second ring flange are connected as an organic wholely.

Further, the diameters of the outer diameter surfaces of the first flange plate and the second flange plate are 100-300mm.

Further, the chamfer is at an angle of 1×45 °.

Further, the diameter of the outer diameter surface of the central shaft of the spool is 50-150mm.

Further, the thickness of the first flange plate and the second flange plate is 5-10mm.

The utility model has the advantages that: the alloy steel material has higher intensity and hardness, can bear great loading and stress, and this makes spool be difficult to warp or damage in the use to prolonged its life, spool center pin, first ring flange and second ring flange adopt the integral type connected mode, provide stronger structural integrity, and this kind of connected mode has reduced the not hard up and the friction between the spare part, has increased spool's stability and reliability.

In the figure: 1-I-shaped wheel center pin, 2-first ring flange, 3-second ring flange, 4-chamfer.

Detailed Description

In order that those skilled in the art will better understand the present utility model, a technical solution in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

In the description of the present utility model, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1, a spool made of alloy steel comprises a spool central shaft 1, a first flange plate 2 is arranged at the top of the spool central shaft 1, a second flange plate 3 is arranged at the bottom of the spool central shaft 1, chamfers 4 are arranged at the edges of the first flange plate 2 and the second flange plate 3, the spool central shaft 1, the first flange plate 2 and the second flange plate 3 are made of alloy steel, and the spool central shaft 1, the first flange plate 2 and the second flange plate 3 are integrally connected.

The diameter of the outer diameter surfaces of the first flange plate 2 and the second flange plate 3 is 100-300mm. The smaller outer diameter surface generally corresponds to a lighter spool structure, and the lighter spool structure is beneficial to reducing the overall load and energy consumption and improving the efficiency and the responsiveness of the system; the chamfer angle 4 is 1 multiplied by 45 degrees, the design of the chamfer angle 4 is beneficial to improving the fatigue resistance of the spool, and the stress concentration can be reduced and the generation and the expansion of fatigue cracks can be delayed through the design of the chamfer angle; the diameter of the outer diameter surface of the spool central shaft 1 is 50-150mm, and the larger diameter of the outer diameter surface generally corresponds to the larger diameter of the spool central shaft, so that the structural strength and rigidity of the spool can be improved; the thickness of the first flange plate 2 and the second flange plate 3 is 5-10mm. Thicker flanges may provide higher strength and rigidity.

Working principle: the utility model is mainly a spool, first, through clamping the first flange plate 2 and the second flange plate 3, then twine the metal wire on the outside diameter surface of the spool central shaft 1, connect as an organic whole between first flange plate 2, second flange plate 3 and the spool central shaft 1, the first flange plate 2, second flange plate 3 and spool central shaft 1 material are alloy steel, compared with the spool that the tradition welds, it has better high strength and outstanding durability, the alloy steel material has higher intensity and hardness, can bear great loading and stress, this makes the spool difficult to warp or damage in the use, thus has lengthened its life, the chamfer 4 design helps to improve the fatigue resistance of the spool, can reduce the stress concentration, delay the production and expansion of the fatigue crack through the chamfer design.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
