It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As shown in fig. 1, the utility model provides an annular heat-generating body device of buckling, it is equipped with winding body 20 and buckles guide pillar 2, buckles guide pillar 2 and is connected with the winding face of winding body 20, and the winding face of winding body 20 and the internal surface phase-match of annular heat-generating body 10 buckle the position adaptation setting of guide pillar 2 and buckle the department at annular heat-generating body 10. Before producing the ring-shaped heating element 10, firstly, designing and manufacturing a matched winding body 20 according to the size and the shape of the inner surface of the produced ring-shaped heating element 10, so that the winding surface of the winding body 20 is matched with the size and the shape of the inner surface of the ring-shaped heating element 10; then, the bending guide post 2 is installed on the winding surface of the winding body 20, so that the position of the bending guide post 2 is adapted to the bending position of the annular heating element 10. When the rod member of the annular heating element 10 is bent, the rod member of the annular heating element 10 is closely attached to the winding surface of the winding body 20, and the bow-shaped/snake-shaped trend of the rod member is guided according to the shape of the annular heating element 10, and in the process, the bending guide pillars 2 which are previously installed on the winding surface of the winding body 20 are sequentially bent, and finally the bending of the whole annular heating element 10 is completed. The utility model provides an annular heat-generating body 10 device of buckling, it is buckled with the help of the instrument, simple structure, labour saving and time saving.
As preferred embodiment, the utility model discloses still be equipped with spacing guide pillar 30, spacing guide pillar 30 is connected with the winding face of winding body 20, carries on spacingly to the member of annular heat-generating body 10, plays the effect that spacing atress supported. For example, considering that the rod of the annular heating element 10 is deformed and displaced by force at the head/tail bending position, the limiting guide pillar 30 is arranged at the starting segment rod of the annular heating element 10 to limit the starting segment rod of the annular heating element 10, and the starting segment rod is arranged before the first bending position of the annular heating element 10, namely the first bending 11 in fig. 1; the starting segment rod can be limited and arranged between the limiting guide pillar 30 and the first bending guide pillar 21. Or, the limiting guide post 30 may also be arranged at the tail section rod of the annular heating element 10 to limit the tail section rod of the annular heating element 10, and the tail section rod is arranged after the last bending position of the annular heating element 10; the tail section rod piece can be limited and arranged between the limiting guide pillar 30 and the bending guide pillar 2 located at the last bending position.
As a preferred embodiment, after the rod member of the annular heating element 10 is bent for a plurality of times, stress concentration is inevitably formed at the bent position, and the rod member of the annular heating element 10 is additionally stressed due to the limitation of a plurality of bending guide pillars 2, so that the internal stress to be overcome by the subsequent bending becomes larger and larger, therefore, the bending guide pillars 2 are detachably connected with the winding surface of the winding body 20, and when the rod member of the annular heating element 10 is bent, one or more bending guide pillars 2 which have been bent and wound before are selectively removed, so as to reduce the stress point of the rod member of the annular heating element 10, and facilitate the subsequent bending. As a further preferred embodiment, the winding surface of the bending guide pillar 2 and the winding body 20 is screwed or pinned, so that the installation and the removal of the bending guide pillar 2 are more convenient.
In a preferred embodiment, the winding surface of the winding body 20 is a cylindrical surface, and is suitable for a circular heating element. The wound body 20 may be a cylinder or a cylinder.
As a preferred example, the material of the ring-shaped heating element 10 is tungsten or molybdenum having a high melting point, and in particular, tungsten has a very high melting point, a very high hardness, a very low vapor pressure, a small evaporation rate, and a relatively stable chemical property, and is widely used as a heating element material.
In order to understand the technical solution of the present invention more fully, as shown in fig. 1, the bending process of the ring-shaped heating element 10 is described by taking the bending as an example, the winding body 20 is cylindrical, and the inner surface of the ring-shaped heating element 10 matches with the winding surface of the winding body 20. Corresponding to the first bend 11, the second bend 12 and the third bend 13 of the ring-shaped heating element 10, a first bend guide post 21, a second bend guide post 22 and a third bend guide post 23 are respectively installed at positions corresponding to the winding surface of the winding body 20. The rod piece of the annular heating element 10 bypasses the first bending guide post 21 according to the size of the product to form a first bending 11, the limiting guide post 30 plays a role in limiting, stress and supporting the rod piece which is bent for the first time, and according to the same method, the second bending 12 and the third bending 13 are sequentially formed, the later bending is analogized, so that the description is not repeated, and the bending of the annular heating element 10 is finally completed. In the whole bending process, the rod body of the annular heating body 10 is always tightly attached to the cylindrical winding surface of the winding body 20.
After the first bending 11, the second bending 12 and the third bending 13 are formed, stress concentration exists at the bending position of the rod piece of the annular heating element 10, and at the moment, the first bending guide post 21 can be detached, so that the stress point of the rod piece of the annular heating element 10 is reduced, and the subsequent bending operation is more convenient. Following this principle, the bending guide posts 2 on the winding body 20 are all detachable, and if necessary, only the first two bending guide posts 2 at the current bending point are retained to release the redundant stress points on the rod member of the ring-shaped heat-generating body 10. Obviously, with the increase of the bending points behind the rod of the annular heating element 10, the individual bending guide pillars 2 can be properly reserved at the bending positions generated in the front for only limiting and supporting, so as not to increase too many stress points.
It should be noted that the present invention is applicable to bending of an annular heating element, which can be integrated, can be formed by assembling two semicircular bent heating element rods into an annular shape, and can also be formed by assembling a plurality of bent heating element rods into an annular shape.
