Abstract
The utility model discloses a flange for a communication tower, and the flange comprises a flange body, wherein bolt holes are uniformly arranged on the junction surface of the flange body, each bolt hole is guided out towards the outer edge of the flange to form an open stress relieving groove, the center line of the stress relieving groove passes through the center of the flange, the width of the stress relieving groove is 6mm, 2mm positive-negative deviation is permitted when processing, and the outer edge of the flange is round or polygonal; the stress relieving groove in the utility model can be use for efficiently releasing residual stress generated when processing and manufacturing, the deformation is reduced, and the processing precision of the flange is ensured; and therefore, the flange has good mechanical behavior, the bolt holes and stress relieving groove of the flange can be molded by cutting once, the processing and manufacturing efficiency is improved, the processing cost is reduced, and the flange has good economic benefit.
Description
Technical field
The utility model relates to a kind of communication tower accessory, is specifically related to a kind of flange that is used for communication tower.
Background technology
Present developing rapidly along with the home communications industry; The communications infrastructure is fast lifting also; The single-pipe tower of communicating by letter in recent years in the tower mast is used extensive day by day, but the machining stress control in the mill of steel work product is the difficult point of restriction industry development always in large-scale single-pipe tower design, process.
The basis flange is a topmost building block in the self-supporting head tower mast structure; Be used for fixing body of the tower and basic firmware, require to have good intensity and precision, the flange of industry employing at present is shaped as loop configuration; Process the connecting hole that needs above, the inner ring and the tower body of flange weld.The process of flange is generally flame cutting, and circle cuts hole again and cuts cylindrical at last in cutting earlier, and steel plate is through heating repeatedly between often, and very complicated variation takes place internal stress, and the workpiece of completion of processing has very big distortion usually, can't guarantee effective precision.
The utility model content
The utility model purpose: the purpose of the utility model is the deficiency to prior art, provides a kind of communication tower that can reduce stress deformation to use flange.
Technical scheme: the described a kind of communication tower of the utility model is used flange, comprises flange body, evenly is provided with several bolts hole on the joint face of said flange body, and securing member passes bolt hole and clamps said flange and basic firmware; Each bolt hole is drawn a uncovered stress-removal groove respectively to the flange outward flange, is used for discharging the residual stress that process produces.During the processing flange, available flame cutting is disposable with flange outward flange, stress-removal groove and bolt hole excision forming, reduces the repeated heating number of times, avoids distortion.
Further improve technique scheme, the center line of stress-removal groove is through the center of flange, and the width of stress-removal groove is 6mm, allows to add the positive and negative deviation that 2mm is arranged man-hour.
The outward flange of flange is circle or polygon, and inward flange and tower body directly weld, and also can add gusset according to the structural strength needs and strengthen fixing.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, the stress-removal groove can effectively discharge the residual stress that produces in the processing and manufacturing, reduces distortion, has guaranteed the machining accuracy of flange, makes flange have good stress performance; 2, the bolt hole of flange and stress-removal groove can excision formings, improved processing and manufacturing efficient, cut down finished cost, and have good economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of the said stress-removal groove of the utility model.
The specific embodiment
A kind of communication tower as shown in Figure 1 is used flange, comprises flange body, evenly has 12 bolts hole on the joint face of flange body, and securing member passes fastening said flange of aperture and basic firmware; Each bolt hole is drawn a uncovered stress-removal groove respectively to the flange outward flange, is used for discharging the residual stress that process produces.During the processing flange, the circle back is disposable with flange outward flange, stress-removal groove and bolt hole excision forming with the flame cutting in having cut, and reduces the repeated heating number of times, avoids distortion, guarantees precision.
As shown in Figure 2, the center line of stress-removal groove is through the center of flange, and the width of stress-removal groove is 6mm, allows to add the positive and negative deviation that 2mm is arranged man-hour.
The outward flange of flange is circular, and inward flange and tower body directly weld.
Claims (4)
1. a communication tower is used flange, it is characterized in that, comprises flange body, evenly is provided with bolt hole on the joint face of said flange body, and each bolt hole is drawn a uncovered stress-removal groove to the flange outward flange.
2. communication tower according to claim 1 is used flange, it is characterized in that, the center line of said stress-removal groove is through the center of flange.
3. communication tower according to claim 1 is used flange, it is characterized in that, the width of said stress-removal groove is 6mm ± 2mm.
