Description

Technical Field

[0001] The present application relates to the technical field of coil frame bending, and in particular to a coil frame bending device. Background Art

[0002] The skeleton coil has now introduced a structure with embedded pins (generally lugs / pins) to optimize the coil winding process. This skeleton coil includes a skeleton, a wire and a pin. During processing, one end of the wire needs to be connected to one of the pins first. After the wire is completely wound on the skeleton, the tail end of the wire needs to be wound on another pin, and the two ends of the wire need to be soldered to the two pins.

[0003] After soldering, the pins need to be bent. The consistency of the bending of the bobbin coil pins is one of the criteria for judging the quality of the bobbin coil. Different products use different bobbin coils, and the number, position, and bending angle of the pins on the bobbin coils also vary.

[0004] For example, the patent with publication number CN206483855U specifically discloses a coil skeleton bending tool, including a base plate, a support column, an upper plate, a cylinder, a connecting head and a fixed frame assembly; thereby, by adopting a cylinder to drive automatic bending, the processing efficiency is high, and the bending angle and length of each skeleton are unified, thereby improving the product qualification rate.

[0005] When the above patent bending device is used, multiple sets of clamps are inserted into the center hole of the frame to fix the frame. Since multiple sets of clamps are fixed, it can only fix frames of fixed size. Secondly, since different products use different frame coils, the number, position and bending angle of the pins on the frame coils are also different, so it is not suitable for fixing frame coils of different sizes. Therefore, it is necessary to design a coil frame foot bending device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

Since the multiple sets of clamps are fixed, only skeletons of fixed sizes can be fixed. Secondly, since different products use different skeleton coils, the number, position and bending angle of the pins on the skeleton coils are also different, so it is not suitable for fixing skeleton coils of different sizes.

[0009] Furthermore, an anti-slip pad is provided at the contact position between the right-angle clamping groove and the coil frame.

[0010] Furthermore, a slide rail is installed on the workbench, a placement groove adapted to the slide rail is opened on the workbench, a slider is installed on the slide rail, and the clamp is installed on the slider.

[0011] Furthermore, a pressing block is installed at the output end of the second cylinder, four groups of limiting columns are installed on the support plate, the limiting columns penetrate the pressing block, and the bending block is installed on the pressing block.
