Abstract
The utility model provides a square coil winding pressing device of a power transformer. The device respectively controls two pinch rollers, using two sets of pneumatic mechanisms. The pinch roller in the front corresponding to the running direction of a drawing die firstly presses conducting wires on a winding drawing die; when the pinch roller gets across the corner angle of a square drawing die and shifts to a rear working face, the pinch roller in the back corresponding to the running direction of the drawing die continues to press the conducting wires on the original working face. Thereby, the conducting wires are wound smoothly. The method is reliable and effective.
Description
The utility model relates to a kind of lead hold down gag of power transformer winding coiling, specifically a kind of square coil coiling hold down gag.
In the present prior art, the equal coiling of the coil of power transformer is circular, and this coil adopts vertical or horizontal coil winding machine coiling, utilizes the air clamper that has a pinch roller to compress lead during coiling, and method is easy.But for the transformer that adopts square coil, because winding former is square, and conductor material has certain elasticity and hardness, and when utilizing the coiling machine to come coiling, above lead hold down gag is difficult to make on the online mould of the smooth coiling of lead.
The purpose of this utility model just provides a kind of reliable, the coiling hold down gag of effective power transformer square coil, and it can compress lead, makes it smooth.
The purpose of this utility model is achieved in that the coiling hold down gag utilizes two pinch rollers of control respectively of two cover pneumatic mechanisms.With respect to the line mould direction of motion the preceding pinch roller at first lead is pressed on the winding former, when the corner angle of crossing square line mould when this pinch roller are transformed into back one working face, with respect to the line mould direction of motion after pinch roller continue to compress lead at former working face, thereby guarantee that the lead coiling is smooth.
Because the utility model has adopted the hold down gag of the two pneumatic mechanisms of a cover, double pressing roller type, so can continue to remain on the pressure of former working face when lead is pressed on follow-up work face.Simultaneously, apply pressure on the online mould,, therefore can compress online mould surface to lead reliably so can adjust pressure along with the variation of the movement position of winding former owing to can control two pinch rollers respectively.
Further describe for the utility model below in conjunction with description of drawings and embodiment.
Fig. 1 is the structure chart of hold down gag.
What Fig. 1 represented is structure chart of the present utility model, the square line mould [1] of the main shaft drives mechanism drive installation of coil winding machine on main shaft, and hold down gag compresses online mould [1] surface to lead by two pinch rollers [2] [3].Contact roller [2] [3] is installed in the head end of rigidity crank [5].Rigidity crank [5] is connected on the movable stand [4] by axle, and the end of rigidity crank [5] is connected in the pneumatic clamping mechanism [6].During coil winding, the coil winding machine control unit is adjusted the pressure of contact roller [2] [3] automatically according to the run location of line mould [1].Line mould position as shown in Figure 1, two pinch rollers of contact roller [2] this moment [3] are pressed on the same working face of line mould, after the line mould turns over certain angle, with respect to the line mould direction of motion the preceding the both main pinch roller of pinch roller [2] more the corner angle of Go-over mould lead is compressed on the follow-up work face of online mould, and with respect to the line mould direction of motion after pinch roller both still keep-uped pressure at former working face from pinch roller [3].After also crossing the ambiguous angle of line from pinch roller [3], master and slave pinch roller [2] [3] all is pressed on the new working face.
Claims (1)
1. the coiling hold down gag of a power transformer square coil, this device has a movable stand [4], movable stand [4] is being fixed pneumatic clamping mechanism [6] and rigidity crank [5], the end of rigidity crank [5] links to each other with pneumatic mechanism [6], head end links to each other with pinch roller [2] [3], it is characterized in that having two cover pneumatic mechanism [6] and two pinch rollers [2] [3].
