Abstract
The utility model provides a transformer silicon steel sheet punching and feeding device which comprises a base, a rotating shaft and a plurality of arc plates. A bearing support is arranged on the base, one end of the rotating shaft is installed in the bearing support through a bearing, a first fixed sleeve, a second fixed sleeve, a moveable sleeve and a thread are arranged at the cantilever arm end of the rotating shaft, the plurality of arc plates are distributed on the circumference with the axis of the rotating shaft serving as the center, each arc plate is respectively hinged to the first fixed sleeve and the second fixed sleeve through two connection rods, each arc plate is respectively connected with one end of a second connection rod, the other end of the second connection rod is hinged to the movable sleeve, and the movable sleeve is connected with a propelling nut. The transformer silicon steel sheet punching and feeding device can prevent silicon steel sheets from being twisted, deforming and being stressed in punching and feeding, prevents no-load loss of a transformer core from increasing, guarantees product quality and greatly improves production efficiency. The transformer silicon steel sheet punching and feeding device has the advantages of being simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of transformer silicon steel sheet punching pay-off
Background technology
At present, play the laminated core structure that adopts mostly unshakable in one's determination of magnetic conduction and skeleton function in the transformer, and being electrical steel sheet by multilayer different length and width, laminated core is formed by stacking, its production process is generally: the independent bundling that earlier a whole volume silicon steel material is divided into various different in width by the longitudinal shear line, utilize punch press that each independent bundling is cut into required transformer core silicon steel sheet then, at last various electrical steel sheets are stacked up according to certain rules, promptly finish after clamping with anchor clamps.Wherein each independent bundling is cut into required this process of transformer core silicon steel sheet with punch press, the way of now a lot of manufacturing factories is directly independent bundling silicon steel sheet to be lain against ground, hold external end head by the punch press staff then and carry out punching, in the punching process, the staff is backrush blowing on bundling constantly, not only time-consuming but also require great effort, production efficiency is difficult to improve, the more important thing is, blowing can make silicon steel sheet produce torsional deformation and stress like this, has increased the open circuit loss of transformer core greatly.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of labor strength, transformer silicon steel sheet punching pay-off that production efficiency is high of reducing.
The technical scheme that the utility model adopted is: comprise pedestal, rotating shaft and polylith arc, pedestal is provided with bearing block, described rotating shaft one end is installed in the bearing block by bearing, the rotating shaft cantilever end is provided with first fixed muffle, second fixed muffle, quill and screw thread, it is on the circumference at center that described polylith arc is distributed in the shaft axis, one end of every arc and two connecting rods is hinged, two connecting rods be arranged in parallel, and the other end of two connecting rods is hinged with first fixed muffle and second fixed muffle respectively; Every arc is hinged with an end of a second connecting rod respectively, and the other end and the quill of second connecting rod are hinged, and quill is connected with pushnut, and pushnut is located on the screw thread of rotating shaft.
In the above-mentioned transformer silicon steel sheet punching pay-off, it is on the circumference at center that described polylith arc is evenly distributed on the shaft axis.
The beneficial effects of the utility model are: four arcs of the present utility model can be formed a cylinder that can change diameter, can carry out blowing to the silicon steel sheet bundling of various different inner diameters, different in width, have simple in structure, easy to operate advantage; Can prevent that silicon steel sheet from producing torsional deformation and stress when the punching feeding, guarantee that therefore the open circuit loss of transformer core can not increase, guarantee product quality; Can also enhance productivity greatly in addition.

Fig. 2 is a left view of the present utility model;
Fig. 3 is a work schematic diagram of the present utility model.
Specific implementation method
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, the utility model comprises pedestal 10, rotating shaft 1 and four arcs 5, pedestal 10 is provided with bearing block 9, one end of described rotating shaft 1 is installed in the bearing block 9 by bearing, and the cantilever end of rotating shaft 1 is provided with first fixed muffle 8, second fixed muffle 7, quill 3 and screw thread 12.The axis that described four arcs 5 are evenly distributed on rotating shaft 1 is on the circumference at center, one end of every arc 5 and two connecting rods 4 is hinged, two connecting rods 4 be arranged in parallel, and the other end of two connecting rods 4 is hinged with first fixed muffle 8 and second fixed muffle 7 respectively.Every connecting rod 4 on second fixed muffle 7 is hinged with an end of a second connecting rod 11 respectively with the hinged place of corresponding arc 5, the other end of second connecting rod 11 and quill 3 are hinged, quill 3 is connected with pushnut 2, and pushnut 2 is located on the screw thread 12 of rotating shaft.The equal in length of the length of described second connecting rod 11 and connecting rod 4.
As shown in Figure 3, four arcs 5 can be formed a cylinder that can change diameter, drive quills 3 motions by the pushnut in the rotating shaft 12, and then drive amplification that second connecting rod 11 and connecting rod 4 motions realize drum diameter and dwindle.During use, earlier pushnut 2 is outwards twisted, drive quill 3 and outwards move, will be dwindled by the outside diameter of cylinder that four arcs 5 are formed, the silicon steel sheet bundling 13 that will prepare punching then is enclosed within on the cylinder.Locate postpone, pushnut 2 is inwardly twisted, the diameter of cylinder will correspondingly increase like this, till the inner ring swelling of silicon steel sheet bundling 13 is fixing, when the staff uses punch press punching silicon steel sheet, as long as starting of pulling silicon steel sheet bundling 13, cylinder will rotate blowing, need not manual backrush blowing.Otherwise,, just remaining silicon steel sheet bundling 13 can be unloaded down from cylinder by above opposite step if stop punching.
