Description
Technical field
The utility model relates to a kind of steel wire shaping device, but the shaped device of the string of production waveform specifically bar.
Background technology
Steel band is as the carrying member of ribbon conveyer, and it is made up of silk screen and the carrying steel disc that is arranged on described silk screen top.Commonly used silk screen be welded after will per two net bars being connected in series by the string bar (its detailed structure can referring to Chinese patent literature CN20100748Y) in the prior art, the shape spring-like of net bar spiral yarn shaped, section is the flattening shape, the string bar be shaped as waveform; As the part of silk screen, the quality of net bar and the moulding of string bar all can influence the total quality of silk screen.Therefore, have only the compact dimensions of net bar to reach the higher spiral flatness in surface, and the flexibility of string bar cooperates the radian of net bar helical buckling, just can guarantee the Forming Quality and the surface smoothness of silk screen, thus guarantee steel band be subjected to tensile force and driving force double action lower stress evenly, operate steadily, sideslip not.
For the moulding of wave string bar, in the prior art, Chinese patent literature CN2917869Y discloses a kind of W shape continuous bend reinforcement component shaped device, and it comprises a pair of main shaft that is parallel to each other, and described main shaft is installed on the frame by bearing block; The gear that pair of matched is closed is mounted on the main shaft respectively; Described main shaft drives its reverse rotation by the drive unit in this shaped device, and the gear that drive is arranged on the described main shaft carries out reverse rotation mutually, reinforcing bar enters in the intersection slit of two parallel gears, thereby reinforcing bar is carried out continuous extruding makes it that continuous bending, the continuous bend reinforcement component that molds W shape take place.
In this technology, between described two gears is intermeshing, on described gear, do not have the relative set governor motion, so the spacing between above-mentioned two gears is fixed, when this just requires to use this device to carry out the moulding of W-shaped steel rib component, the reinforcing bar that uses must be the reinforcing bar material of unified diameter, be difficult to satisfy simultaneously the pressing requirements of different reinforcing bar of diameter or steel wire, if enlarge when adjusting according to producing the diameter of needs to the reinforcing bar material, said apparatus just can't use so, cause the waste of manufacturing machinery, strengthened manufacturing cost; Perhaps need gear is correspondingly changed, make the gear spacing satisfy reinforcing bar or gauge of wire, influenced production efficiency so again greatly.
Above-mentioned string bar is in the process of processing and manufacturing, because the rotation that is meshing with each other of gear, it drives reinforcing bar or the steel wire do not enter the gear position and also shakes in the process of advancing, so easy rate of curving that influences string bar after the moulding, thus influence the surface smoothness of silk screen on the whole.
The utility model content
First technical problem to be solved in the utility model is that two pitch wheel spacings are to fix in the string bar shaped device of the prior art, like this when reinforcing bar or steel wire diameter become big, shaped device originally then can not re-use, need more exchange device or more gear changing, caused the waste of manufacturing machinery, influenced production efficiency and also strengthened the manufacturing cost of string bar, thus provide a kind of can the adjusting gear spacing and be applicable to the reinforcing bar of any diameter or the string bar shaped device of steel wire.
Second technical problem to be solved in the utility model is in the string bar shaped device of the prior art any position-limit mechanism to reinforcing bar or steel wire not to be set, so easily because gear meshing is rotated the described reinforcing bar of drive or steel wire is shaken, influence reinforcing bar or the steel wire string bar rate of curving after moulding, can realize it is carried out spacing string bar shaped device in the bar moulding in that reinforcing bar or steel wire are gone here and there thereby provide a kind of.
For solving the problems of the technologies described above, the utility model provides a kind of waveform string bar shaped device, comprises briquetting machine and main shaft drives mechanism; Described briquetting machine comprises frame, be arranged at two parallel main shafts on the described frame, on each described main shaft, be respectively arranged with a mould gear, be provided with at regular intervals between two described mould gears, described spacing and steel wire diameter adapt, and the corresponding cooperation of described mould gear is rotated, and described steel wire is suppressed; Also be provided with the main shaft adjusting device, described main shaft adjusting device is connected with at least one main shaft in the described main shaft, regulates described main shaft and moves along the axial connecting line direction of two main shafts.
