Background

A Transformer (Transformer) is a device for changing an ac voltage by using the principle of electromagnetic induction, and is mainly composed of an iron core (or a magnetic core) and a coil.

The existing transformer needs to axially extend heads at the upper end and the lower end of a coil after the coil is wound. The copper flat wire with the axial head protruding needs to be perpendicular to the coil when the head protrudes, so that the flat wire needs to be folded at an angle of 90 degrees in the width direction, and the operation is generally carried out by means of a special tool. For a single flat wire with large section size and width and small thickness, the bending operation along the width direction is difficult.

The existing wire bending tools are generally bent by a three-point structure as shown in patents CN206382466U and CN206854531U, however, the existing tools are difficult to be adapted to flat wires with different widths and thicknesses due to the fixed size.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be understood as imposing any limitation on the scope of the present invention.

As shown in fig. 1 to 3, an embodiment of the present application provides a transformer flat wire bending device, which includes two independent flat wire fixing clamps 1, where each flat wire fixing clamp 1 includes a connecting rod 2 and clamping mechanisms 3 disposed at two ends of the connecting rod. Referring to fig. 2, the clamping mechanism 3 includes a width-direction clamping assembly, and the width-direction clamping assembly includes a pair of clamping blocks 4, and the pair of clamping blocks 4 can move towards or away from each other along the horizontal direction, so as to clamp and release the flat wire of the transformer in the width direction. Be provided with thickness direction clamping assembly on every clamp block 4, thickness direction clamping assembly includes compact heap 5, and compact heap 5 can be followed vertical direction and moved to the realization compresses tightly and unclamps the transformer flat wire in thickness direction.

Because the thickness direction clamping component is arranged on the clamping block 4, the flat wire can be put in from the upper part of the device during clamping, and therefore the flat wire can be directly bent no matter what part of the flat wire is provided with the bent part. The existing bending tool needs to send the end of the flat wire into the tool, pull the flat wire and move the bending tool to the part to be bent, which wastes time and labor.

In this embodiment, the width direction clamping assembly includes a threaded rod 6, a sliding groove 7 and two sliding blocks 8, the two sliding blocks 8 are connected with the sliding groove 7 in a sliding mode, each clamping block 4 is fixedly connected with one sliding block 8, threads are drawn on the threaded rod 6 in a manual and symmetrical mode, and the threaded rod 6 is connected with the two sliding blocks 8 in a threaded mode. By turning the threaded rod 6, the two sliders 8 can be moved in the opposite or opposite directions. Further, in order to facilitate turning of the threaded rod 6, a turning knob 9 may be provided at one end of the threaded rod 6.

In addition, in order to keep the threaded rod 6 fixed in position while rotating, a support 10 is provided in the middle of the sliding groove 7, and a through hole is opened in the support 10, through which the threaded rod 6 passes. Other components such as bearing blocks may be used instead of the support 10.

The thickness direction clamping assembly comprises a supporting plate 11, a bolt fixing block 12 and an adjusting bolt 13, the supporting plate 11 is connected with the clamping block 4, the bolt fixing block 12 is fixedly connected with the supporting plate 11, a threaded hole is formed in the bolt fixing block 12, and the adjusting bolt 13 penetrates through the threaded hole and then is connected with the pressing block 5. By screwing the adjusting bolt 13, the pressing block 5 can be driven to ascend or descend.

It should be noted that the width direction clamping unit and the thickness direction clamping unit are only one of possible embodiments, and may be implemented by other structures. For example, the positions of the pressing blocks 5 and the clamping blocks 4 can be adjusted in a mode that the inserted pins are matched with the positioning holes, but the mode is only suitable for flat wires with specific widths and thicknesses. For another example, a spring may be used instead of a thread to maintain the clamping of the clamping block 4 or the pressing of the pressing block 5 by an elastic force, but this structure requires pulling the clamping block 4 to both sides or pulling up the pressing block 5 when in use, which is also inconvenient.

In a possible embodiment, the outer surface of the connecting rod 2 is covered with a rubber layer to give a better feel when gripped. The length of the tie bar 2 is preferably 20cm to 30cm, and in the present embodiment, the length of the tie bar 2 is 23 cm.

In order to prevent the flat wire from being crushed in the fixing process, the rubber layer can be covered on the surface opposite to the clamping block 4, and the rubber layer can be covered on the lower surface of the pressing block 5 to protect the flat wire of the transformer.

When the transformer flat wire bending device is used for bending, the method comprises the following steps: putting the flat wire of the transformer into a flat wire fixing clamp from the upper part; adjusting each width direction clamping assembly, and fixing the flat wire from the width direction; adjusting each thickness direction clamping assembly, and fixing the flat wire from the thickness direction; two hands respectively hold a flat wire fixing clamp and bend inwards (as shown in figure 3); adjusting each thickness direction clamping assembly, and loosening the flat wire from the thickness direction; adjusting each width direction clamping assembly, and loosening the flat wire from the width direction; and taking out the flat wire of the transformer.

Both ends through at every flat wire mounting fixture set up width direction clamping component and thickness direction clamping component to be applicable to the flat wire of different width and thickness. Because can put into the flat wire from flat wire mounting fixture's top, no matter how long flat wire length can both buckle, it is more convenient to operate.
