[0006] Optionally, the pushing block can reciprocally slide relative to the base between a starting position, an intermediate position and a terminating position. When the pushing block is at the starting position, both the first spring and the second spring are in a natural state. When the pushing block is at the intermediate position, the first spring is in a natural state, the second spring is in a compressed state and the forming block abuts against the limiting rod. When the pushing block is at the terminating position, both the first spring and the second spring are in a compressed state and the forming block extends into the forming groove.

[0007] Optionally, the pushing block includes a first pushing portion extending along the second direction and a second pushing portion extending along the second direction, the first inclined surface being located on the second pushing portion, the first spring being connected between the first pushing portion and the limiting block, and the second spring being connected between the first pushing portion and the second forming die.

[0008] Optionally, the forming block includes a first forming portion and a second forming portion. The second inclined surface is located on the first forming portion. The first forming portion is slidably arranged on the limiting block along the second direction.

[0013] Optionally, a push rod is arranged on the pushing block, and the push rod is slidably arranged on the base along the first direction.

[0014] Compared with the prior art, one or more of the above technical solutions in a plug coil pin bending jig provided by an embodiment of the present invention at least have the following technical effects:

[0015] During processing, the coil to be bent can be placed between the first receiving groove and the second receiving groove. The pushing block can gradually move in the first direction. In the initial stage, the pushing block can indirectly abut against the limiting block and the second forming die through the first spring and the second spring, so that the limiting block and the second forming die can move synchronously with the pushing block. When the second forming die abuts against the first forming die, the second forming die stops moving and clamps the coil body between the first forming die and the second forming die; during the process of the forming block moving in the first direction, the forming block first bends the root of the pin, so that the pin forms a first bending angle. Then, during the further movement of the forming block, the forming block will abut against the limit in the first direction. When the pushing block continues to move, the pushing block can abut against the forming block in the second direction through the cooperation of the first inclined surface and the second inclined surface, so that the forming block can press the end of the pin (i.e., the free end of the pin far from the root) into the forming groove, and finally the pins on the coil body can be bent into a multi-segment bent shape. The utility model can realize the multi-segment bending of the pins and meet the special requirements in the production of plugs. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Referring to Figures 1 to 9 , the present utility model provides a plug coil pin bending jig, which includes a base 100, a pushing block 200, a limiting block 300, a forming block 500, a first forming die 600, a second forming die 700, and a limiting rod 110.

[0041] Among them, the pushing block 200 is slidably arranged on the base 100 along the first direction. The pushing block 200 has a first inclined surface 221. The limiting block 300 is slidably arranged on the base 100 along the first direction and is connected to the pushing block 200 through a first spring 400. The forming block 500 is slidably arranged on the limiting block 300 along the second direction, and the second direction is perpendicular to the first direction. The forming block 500 is provided with a second inclined surface 511, and the first inclined surface 221 is in contact with the second inclined surface 511. The first forming die 600 and the second forming die 700 are arranged along the first direction. The first forming die 600 is fixed on the base 100. One end of the first forming die 600 in the first direction is provided with a first receiving groove 610 and at least one forming groove 620 is provided on at least one side in the second direction. The second forming die 700 is slidably arranged on the base 100 along the first direction and is connected to the pushing block 200 through a second spring 800. One end of the second forming die 700 in the first direction is provided with a second receiving groove 720. The first receiving groove 610 and the second receiving groove 720 are arranged oppositely. The accommodating space between the first receiving groove 610 and the second receiving groove 720 is used to accommodate the coil body 900. The limiting rod 110 is arranged on the base 100 along the second direction. The limiting block 300 can move along the first direction until the forming block 500 abuts against the limiting rod 110. After the forming block 500 abuts against the limiting rod 110, the pushing block 200 can, during the sliding process along the first direction, promote the forming block 500 to slide along the second direction through the cooperation of the first inclined surface 221 and the second inclined surface 511. The forming block 500 is configured to be able to bend the lead 910 on the coil body 900 located in the accommodating space when moving along the first direction and to press the end of the lead 910 into the forming groove 620 when moving along the second direction.

[0042] It can be understood that during processing, the coil to be bent can be placed between the first receiving groove 610 and the second receiving groove 720. The pushing block 200 can gradually move in the first direction. In the initial stage, the pushing block 200 can indirectly abut against the limiting block 300 and the second forming die 700 through the first spring 400 and the second spring 800, so that the limiting block 300 and the second forming die 700 can move synchronously with the pushing block 200. When the second forming die 700 abuts against the first forming die 600, the second forming die 700 stops moving and clamps the coil body 900 between the first forming die 600 and the second forming die 700; during the process of the forming block 500 moving in the first direction, the forming block 500 first bends the root of the pin 910, so that the pin 910 forms a first bending angle. Then, during the further movement of the forming block 500, the forming block 500 will abut against the limiting rod 110 in the first direction. After the pushing block 200 continues to move, the pushing block 200 can abut against the forming block 500 in the second direction through the cooperation of the first inclined surface 221 and the second inclined surface 511, so that the forming block 500 can press the end of the pin 910 (i.e., the free end of the pin 910 away from the root) into the forming groove 620, and finally the pins 910 on the coil body 900 can be bent into Figure 9 the shown form. The utility model can realize multi-stage bending of the pins 910 and can meet the special requirements in plug production.

[0043] As Figures 1 to 8 shown, in some embodiments of the present utility model, the pushing block 200 can reciprocally slide relative to the base 100 between the starting position, the middle position and the ending position.

When the pushing block 200 is at the middle position, the first spring 400 is in the natural state, the second spring 800 is in the compressed state and the forming block 500 abuts against the limiting rod 110. When the pushing block 200 is at the ending position, both the first spring 400 and the second spring 800 are in the compressed state and the forming block 500 extends into the forming groove 620. Through the above setting method, the second forming die 700 can first be engaged with the first forming die 600 to stabilize the position of the coil body 900, and the first bending of the pin 910 can be realized before the forming block 500 moves to the position where it abuts against the limiting rod 110.

[0048] As Figures 1 to 8 shown, in some embodiments of the present utility model, there are two limiting blocks 300 arranged in mirror symmetry, and there are two forming blocks 500 arranged in mirror symmetry. The two limiting blocks 300 are arranged along the left-right direction, and the two forming blocks 500 are arranged along the left-right direction. There are two first inclined surfaces 221 on the pushing block 200, and the two first inclined surfaces 221 are respectively in contact with the second inclined surfaces 511 on the two forming blocks 500. Through the above mirror structure, the two pins 910 on the coil body 900 can be bent synchronously, improving the bending efficiency.

[0049] AsFigures 1 to 8 As shown, in some embodiments of the present utility model, two guiding blocks 120 are provided on the base 100. The two guiding blocks 120 are parallel to each other and both extend in the front-rear direction.
