[0033] In this embodiment, the fixing plate 3 is located on the longitudinal center axis of the support platform 1, which can improve the stability of the coil pressing device structure and the convenience of use.

[0034] See also Figures 3 to 4 In order to achieve rapid and accurate pressing of the coil into a circular or waist shape and improve the working efficiency and product quality of the production line, in this embodiment, the driving mechanism 5 includes two first electric push rods 51, two arc-shaped pressure blocks 52, a connecting block 53, a pressure plate 54, a connecting plate 55 and a second electric push rod 56. The two first electric push rods 51 are fixed to the left and right sides of the upper surface of the support platform 1 through a support seat, and the two arc-shaped pressure blocks 52 are arranged on the outside of the output shaft of the left and right first electric push rods 51, the connecting block 53 is arranged on the upper surface of the support platform 1 and is located on the back of the fixed plate 3, the pressure plate 54 is hinged to the upper surface of the connecting block 53 through a hinge seat, the connecting plate 55 is arranged on the upper surface of the support platform 1 and is located on the back of the connecting block 53, the second electric push rod 56 is hinged to the front of the connecting plate 55 through a hinge seat, and the outer side of the output shaft of the second electric push rod 56 is hinged to the back of the pressure plate 54 through the hinge seat.

[0035] In this embodiment, the coil is sleeved on the outside of the arc-shaped forming block 4. By starting the second electric push rod 56, the pressure plate 54 can be driven to cover the upper surface of the arc-shaped forming block 4, and then the first electric push rods 51 on the left and right sides are started. The volume of the arc-shaped pressure block 52 on the right is larger than the volume of the arc-shaped forming block 4, and the volume of the arc-shaped pressure block 52 on the left is smaller than the volume of the arc-shaped forming block 4. The left side of the right arc-shaped pressure block 52 matches the gap on the right side of the arc-shaped forming block 4, and the right side of the left arc-shaped pressure block 52 matches the gap on the left side of the arc-shaped forming block 4.

[0036] In this embodiment, the coil generally refers to a ring-shaped wire winding. The most common coil applications include motors, inductors, transformers, and loop antennas. The coil in the circuit refers to an inductor, which means that the wires are wound one by one. The wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. The coil has a wide range of applications.

[0037] In this embodiment, sliding grooves are provided on the front and rear sides of the right side of the upper surface of the fixed plate 3, and sliders are slidably connected inside the sliding grooves.

The ejection plate 65 moves linearly up and down inside the fixed opening 64, and the gap between the ejection plate 65 and the fixed opening 64 is matched.

[0042] It should be noted that, when the third electric push rod 62 is started, the movable frame 63 is driven to move upward, and the left and right ejection plates 65 are driven to move upward inside the left and right fixed openings 64. By moving the left and right ejection plates 65 upward, the coil sleeved on the outside of the arc forming block 4 can be ejected, making it easier to take out the pressurized and formed coil.

[0043] The working principle of the above embodiment is:

[0044] (1) The coil can be sleeved on the outside of the arc-shaped forming block 4. By starting the second electric push rod 56, the pressure plate 54 can be driven to cover the upper surface of the arc-shaped forming block 4. Then, the first electric push rods 51 on the left and right sides are started to drive the arc-shaped pressure blocks 52 on the left and right sides to move in relative directions, and pressure is applied to the coil sleeved on the outside of the arc-shaped forming block 4 to shape it. The coil can be quickly and accurately pressed into a round or waist shape, thereby improving the work efficiency and product quality of the production line.

[0045] (2) After the coil is pressed into a circular or waist shape, the second electric push rod 56 can be started to drive the pressure plate 54 to flip backward, and then the first electric push rods 51 on the left and right sides are started to drive the pressure plates 54 on the left and right sides to move in opposite directions. After moving a certain distance, the first electric push rods 51 on the left and right sides are closed. At this time, the third electric push rod 62 is started to drive the moving frame 63 to move upward, and drive the ejection plates 65 on the left and right sides to move upward inside the fixed openings 64 on the left and right sides. By moving the ejection plates 65 on the left and right sides upward, the coil set on the outside of the arc forming block 4 can be ejected, making it easier to take out the pressurized and shaped coil.
