The cold-heading resonance rod has the advantages of high efficiency, saving materials, low cost and high precision, and can be widely applied to the communication transmission field.
Description
Technical field
The utility model relates to a kind of communications parts, particularly relates to a kind of cold-heading resonant rod.
Background technology
At present, the resonant rod major part of producing in the filter industry forms by Vehicle Processing, and small part adopts drawing die to be stamped to form.Because the Vehicle Processing resonant rod is by the raw material cutting forming, not only causes the serious waste of material easily, and the speed of manufacturing steel part is slow, tool damage is serious, thereby has increased manufacturing cost greatly.The stretching resonant rod forms with die stamping, when raising the efficiency, cutting the waste, precision has but descended, and makes filter partial properties in actual applications be subjected to influence, and the steel part of stamping parts also has the waste of leftover pieces, and this has also improved manufacturing cost.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of cold-heading resonant rod to be provided, and makes its processing is had efficient height, materials are economized, cost is low, precision is high characteristics.
A kind of cold-heading resonant rod that the utility model provides, the cylindrical shell that comprises both ends open, be provided with the coupling part that cylinder lumen is divided into upper chamber and lower chambers in the middle of the described cylindrical shell, described coupling part and cylindrical shell are the monolithic molding structure, be provided with the aperture that upper chamber and lower chambers are communicated with in coupling part central authorities, be provided with first joint face between the bottom of cylinder inboard wall and cylindrical shell, described first joint face is the conical surface; Be provided with second joint face between the bottom of cylinder body outer wall and cylindrical shell, described second joint face is the cambered surface or the conical surface; Be provided with the 3rd joint face between the top of cylinder body outer wall and cylindrical shell, described the 3rd joint face is a cambered surface.
In technique scheme, the bottom surface of coupling part is the conical surface.
In technique scheme, the cross section of described cylindrical shell is circle or polygon.
In technique scheme, the degree of depth of described upper chamber is greater than the degree of depth of lower chambers.
In technique scheme, the top outer rim of cylindrical shell is provided with collar flange, and is stepped between collar flange and the cylinder body outer wall.
Cold-heading resonant rod of the present utility model, have following beneficial effect: employing cold-heading crimp has the working (machining) efficiency height, materials are economized (not having waste material substantially), big, the stable high advantage of the low distortion of cost, and critical size can reach the specification requirement (precision height) of Vehicle Processing resonant rod, and the cold-heading resonant rod has bigger advantage with respect to tensioning member in size Control, distortion.
