Abstract
The utility model provides a base head structure of large-scale insulator body, its constitution includes: the blank head comprises a blank rod, a transition part and a supporting part, wherein the transition part is positioned between the blank rod and the supporting part, the diameter of the transition part is larger than that of the blank rod and smaller than that of the supporting part, the length of the transition part is 5cm-10cm, and the diameter of the transition part is 1.1-1.2 times of that of the blank rod. The beneficial effects are as follows: the utility model discloses increased transition portion and made the body fire the phenomenon that the in-process blank pole part can not appear drawing and splitting and turn around, improved the yield and the quality of product.
Description
Technical Field
The utility model relates to an insulator manufacturing technology especially indicates a blank head structure of large-scale insulator body.
Background
In the dry manufacturing of large insulators of 800 ten thousand volts and above, a blank body needs to be fired, but because the insulators are heavy, after the existing blank body is manufactured, only a blank rod and a supporting part are arranged at two ends of the blank body, phenomena of pulling crack, turning around and the like generally occur at the cementing part of the insulator, and after the phenomena occur, the whole insulator becomes a waste product, so that the great waste of production resources is caused, and further the manufacturing cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that exists among the prior art, provide a blank head structure of large-scale insulator body.
The technical scheme of the utility model is realized like this: the utility model provides a base head structure of large-scale insulator body which constitutes and includes: the blank head comprises a blank rod, a transition part and a supporting part, wherein the transition part is positioned between the blank rod and the supporting part, and the diameter of the transition part is larger than that of the blank rod and smaller than that of the supporting part.
The length of the transition part is 5cm-10cm, and the diameter of the transition part is 1.1-1.2 times of the diameter of the billet.
The utility model has the advantages that: after the large insulator blank is fired, the redundant parts at the front end and the rear end of the blank rod need to be cut off, and the supporting part and the transition part are cut off; the transition part is added, so that the phenomena of pulling crack and turning around of the billet rod part in the firing process of the billet body can not occur, and the yield and the quality of products are improved.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of a rod insulator.
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 any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, a blank head structure of a large insulator blank comprises: the insulator blank comprises a blank head 5, the blank head 5 is located at two ends of the insulator blank 4 and used for supporting the whole blank 4 during firing, the blank head 5 is composed of a blank rod 1, a transition part 2 and a supporting part 3, the transition part 2 is located between the blank rod 1 and the supporting part 3, the diameter of the transition part 2 is larger than that of the blank rod 1 and smaller than that of the supporting part 3, the length of the transition part 2 is 5cm-10cm, and the diameter of the transition part 2 is 1.1-1.2 times that of the blank rod 1.
The length and the diameter of the transition part 2 are not easy to be overlarge, when the length of the transition part 2 is overlarge, the use of raw materials is increased, the cost is increased, and the structural strength of the blank body 4 is also reduced; when the length and the diameter of the transition part 2 are too small, the phenomenon of turning around and cracking is more easily generated during firing, so the length of the transition part 2 can be adjusted within the range of 5cm-10cm according to the material of the blank body 4 and the firing temperature.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Claims (2)
