Problems solved by technology

However, in the process of clamping the silicon steel sheets, due to manual operation, the pressing force applied to the silicon steel sheets is inconsistent, and it is easy to cause the air between the silicon steel sheets to not be completely discharged with the excess insulating varnish. Bubbles remain in the insulating varnish layer, causing the transformer to resonate and vibrate during use, shortening the service life of the transformer

Embodiment 1

[0028] Such as Figure 1 to Figure 6 As shown, the top of the frame 1 forms an included angle of 10° with the horizontal plane, and two vertical support plates are arranged on both sides thereof, which are respectively the left support plate 3 and the right support plate 2, and the two support plates are provided with positioning holes 11 and the upper shaft hole 26.

[0029] The overturn frame 4 is a rectangular frame formed by connecting the upper beam 22, the left longitudinal beam 23, the lower beam 24 and the right longitudinal beam 25 successively, and is installed horizontally between two support plates, and can rotate relative to the frame along the horizontal axis. Its two sides are connected with the connectors passing through the upper shaft holes 26 of the two support plates. The right longitudinal beam of the overturn frame 4 is provided with a first position hole 10 and a second position hole 9, and the inner surface of the left longitudinal beam 23 is a side sur...

Embodiment 2

[0041] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the overhead pushing device is a top cylinder, and five top cylinders are installed and fixed on the upper beam of the overturning frame in a random distribution.

[0042] The invention is easy to operate and convenient to use. When the iron cores are stacked, the mutual vertical relationship between the contact surfaces between the flip frame and the flip plate can be used to quickly locate. By using machinery instead of manual operation, it avoids the gap between the silicon steel sheets caused by manual operation. Residual air bubbles lead to resonant vibration of the transformer core, thereby prolonging the service life of the transformer core.

Abstract

The invention provides a device for iron core stacking, which includes a machine frame, an overturning frame, an overturning plate, an overhead pushing device, a side pushing device, a locking device and an overturning plate power device; The bearing surface and side blocking surface for iron core stacking and the cover surface matching the cover action of the flip plate; the flip frame is installed on the frame and can rotate relative to the frame along the horizontal axis; the top pushing device is installed on the flip frame The upper part; the side pushing device is installed on the side of the flip frame or at the side of the flip frame; the locking device is installed on the frame to lock the relative angle between the flip frame and the frame; the flip plate is provided with stacking On the datum plane, the turning plate is connected with the action part of the turning plate power device and can rotate relative to the moving part of the turning plate power device. The invention replaces the manual operation by machinery, avoids the resonant vibration phenomenon of the transformer iron core caused by residual air bubbles between the silicon steel sheets due to the manual operation, thereby prolonging the service life of the iron core.

Description

technical field [0001] The invention relates to a stacking machine, in particular to a transformer iron core stacking machine. Background technique [0002] At present, commonly used transformer cores are generally made of silicon steel sheets. A group of silicon steel sheets of the same specification and height are soaked in insulating varnish and stacked neatly, and the excess insulating varnish between each silicon steel sheet is squeezed out through manual clamping, shifting, and flipping processes. In this way, the air between the silicon steel sheets is discharged, and the silicon steel sheets are bonded with insulating varnish to complete the assembly of the transformer core. However, in the process of clamping the silicon steel sheets, due to manual operation, the pressing force applied to the silicon steel sheets is inconsistent, and it is easy to cause the air between the silicon steel sheets to not be completely discharged with the excess insulating varnish. Bub...
