Description
Technical field
The utility model is the steel bar joining head cold roll forming apparatus that a kind of quartering is synchronously exerted pressure, this cold roll forming apparatus adopts the quartering synchronously to exert pressure mode, to form this pole at the position of the contiguous termination of reinforcing bar, compared to traditional cold roll forming apparatus to pressure mode (with the forming pockets of two semicirculars in shape to pressure), the strength of the utility model extrusion molding is comparatively even, in addition, synchronously exert pressure through the quartering and the technical characteristic such as flaring configuration of described forming pockets, the intensity of this pole can not only be made to increase, and reinforcing bar can be avoided in forming process to produce stress concentration point, and then maintain the intensity of steel bar overall.
Background technology
In recent years, because economy is flourish and cause unban population to be concentrated in a large number, in the city of an inch of land is an inch of gold, no matter be that the demand such as commercial use or inhabitation purposes all significantly promotes, add the lifting of modern building technology, therefore, soil, city is caused on using, to present densification and the phenomenon of highly utilizationization, most building develops towards the form of high stratification gradually, and then make the building in city not only more and more intensive, also more and more higher in building height, and stand in great numbers one after another in city along with high-rise building thing, related industry is also driven in the lump, especially the related industry of construction material is engaged in, namely the demand in the face of a large amount of construction material is needed, therefore, how to provide various construction material and semi-finished product fast, namely the related industry and the required emphasis of making great efforts of each dealer of being engaged in construction material is become.
General speech, when building high-storey building, the most often and the most extensively should be belonged to reinforcing bar by the strengthening building materials used, although, reinforcing bar can be used in building structure, to increase overall construction intensity, make building safety and firmness and more durable more, but, because all there is its predetermined scale lengths in manufacturer when making reinforcing bar, therefore, in general construction process, often can produce the problem of " reinforcing bar curtailment ", and in order to solve foregoing problems, dealer is by traditional bar splicing mode, extend reinforcing bar length, only, use traditional reinforcing bar overlapping mode, not only colligation speed is slow, and make outside engineering time and cost significantly improve, still because of factors such as colligation quality good or not inequality and colligation intensity deficiencies, the problem that the reinforcing bar generation bulk strength making colligation overlap is poor.
Therefore, for making reinforcing bar can be applicable to the building of various specification and effectively can improve foregoing problems, building manufacturer and usually can carry out continued access two reinforcing bar with a steel bar connector, to solve the problem of reinforcing bar curtailment in construction process.Look into, refer to Figure 1A, Figure 1B, shown in Fig. 1 C, dealer is front at continued access two reinforcing bar 3 (no matter being slub type reinforcing bar 31 or screw thread nodal pattern reinforcing bar 33), all required first through an existing cold roll forming apparatus (not shown), respectively cold roll forming process is carried out to one end of each this reinforcing bar 3, to form a pole 5 at the position of each this reinforcing bar 3 its termination contiguous, heir, again in successive process, pass through rolling device, this pole 5 rolls out public thread 51, and then form a continued access head, finally, male thread 51 on this two reinforcing bar 3 continued access head is screw-coupled to the female thread (not shown) in a steel bar connector 4, this two reinforcing bar 3 continued access can be made integral, make it can not only be applicable to the building of corresponding specification, still can possess enough bulk strengths.
Only, this existing cold roll forming apparatus system adopts opposite-compacting type to exert pressure (with the forming pockets of two semicirculars in shape to pressure), therefore, this existing cold roll forming apparatus because of extrusion molding strength uneven, and make reinforcing bar in forming process, produce stress concentration point, and then the intensity of generation steel bar overall is by the problem of cutting down, in addition, the slotted eye diameter system of the forming pockets of this existing cold roll forming apparatus is identical with formed pole, without the configuration of flaring, therefore, in the process of the position compressive deformation of the contiguous termination of reinforcing bar, the part material of crimp will embed in the gap between adjacent cold rolling head, and there is the mutually stuck problem of cold rolling head.
Known in sum, how to design one and can not only carry out extrusion molding with even strength, and possess many hydraulic jacks to share the cold roll forming apparatus of operating pressure, can in the process that reinforcing bar is exerted pressure, effective part material improving steel bars distortion embeds the phenomenon between adjacent cold rolling head in gap, and then avoid the mutually stuck problem of cold rolling head occurs, namely become the utility model this for inquire into important topic.
Utility model content
Because existing cold roll forming apparatus has aforesaid shortcoming in design, creator is the practical experience dropping into related industry according to it all the year round, through meticulous inspection and research and development, and through repeatedly adjusted design and measures of effectiveness, finally development and Design goes out the steel bar joining head cold roll forming apparatus that the quartering of the present utility model is synchronously exerted pressure, to overcoming aforesaid problem at one stroke with the utility model.
