[0001] The utility model relates to the field of transformer coil production, and particularly relates to a coil cutting device. Background Art
[0002] A transformer coil is an electric coil used in a transformer to generate a magnetic field and transmit electric energy.
[0003] In the current existing technology, after the transformer coil of a small electronic device is wound, the staff needs to cut the pins of the coil to make their lengths uniform for subsequent welding. The existing cutting device mainly consists of a workbench, a cylinder and a cutting knife. A pair of slots are arranged above the workbench, and the slots are used to insert the pins on both sides of the coil. Then, the cylinder drives the cutting knife to cut the redundant pins of the coil neatly.

The redundant part cut off is below the lower seat 19. Then, the first cylinder 16 is relied on to drive the cutting scissors 17 to move, so as to cut off the redundant leads on the coil. During the use process, the staff can rotate the screw 14 to drive the bottom plate 12 to move up and down, so as to adjust the distance between the coil and the lower seat 19, thereby adjusting the cutting length of the leads accordingly, so as to improve the applicable range and facilitate meeting the requirements for leads of different lengths.
[0025] Further, as Figures 1-2 shown, a fixing seat 21 is fixedly connected to the top of the bottom plate 12; a coil groove 22 is formed in the top of the fixing seat 21; an opening is formed at a position corresponding to the slot 15 at the bottom of the coil groove 22; during use, the coil is placed into the coil groove 22 above the fixing seat 21 from above, and the coil groove 22 can be relied on to position the coil and provide a certain fixing and supporting effect, and the pins of the coil are inserted from the opening at the bottom.
[0026] Further, as Figures 2-3 shown, vertical rods 31 are fixedly connected to the bottom of the bottom plate 12; sliding sleeves 32 are fixedly connected to the support 13 at positions corresponding to the vertical rods 31; the vertical rods 31 penetrate through the sliding sleeves 32 and are slidably connected thereto; a plurality of vertical rods 31 are provided; during use, by relying on the cooperation of the plurality of vertical rods 31 and the sliding sleeves 32, the up-and-down movement of the bottom plate 12 can be guided, thereby improving the stability of its movement, and further facilitating the guarantee of the cutting accuracy and stability.
[0027] Further, as Figures 1-2 and Figure 4 shown, a second cylinder 41 is fixedly connected to the side of the workbench 11; a push frame 42 is fixedly connected to the output end of the second cylinder 41; connecting rods 43 are hinged to both sides of the push frame 42; the end of the connecting rod 43 is hinged to a sliding seat 44; a clamping rod 45 is fixedly connected to the side of the sliding seat 44 away from the first cylinder 16; the clamping rods 45 are located on both sides of the lower seat 19; during use, by relying on the setting of the second cylinder 41, the push frame 42 can be driven to move, so as to drive the sliding seats 44 to approach or move away from each other through the two connecting rods 43, and the movement of the sliding seats 44 will drive the clamping rods 45 to move. The clamping rods 45 can be relied on to fix the pins from both sides, and when some pins are bent, the extrusion of the clamping rods 45 can play a certain role in leveling, which is convenient for cutting and improves the cutting accuracy.
[0028] Further, as Figures 1-2 shown, a slide rail 5 is fixedly connected to the top side of the workbench 11; a chute is formed in the bottom of the sliding seat 44; the slide rail 5 is slidably connected to the chute; during use, when the sliding seat 44 moves, the sliding seat 44 will slide correspondingly on the slide rail 5, so that the movement of the sliding seat 44 and the clamping rod 45 can be positioned and guided, thereby improving the stability of the movement of the clamping rod 45 and facilitating the maintenance of the clamping effect on the pins.
[0029] Further, as Figure 5As shown, a connecting groove 6 is formed at the bottom of the upper seat 18; the lower seat 19 is inserted into the connecting groove 6 and is slidably connected thereto; during use, due to the provision of the connecting groove 6, it serves to shield the connection between the upper seat 18 and the lower seat 19, thereby reducing the extrusion of the clamping rod 45 and preventing the pins from being completely embedded into the gap between the upper seat 18 and the lower seat 19.
[0030] Furthermore, as Figure 3 shown, the side surface of the cutting scissors 17 is designed in a trapezoidal structure. Due to this setting, when cutting the pins, the contact with the pins is released one by one for cutting.
[0031] Working principle: During use, the staff places the coil above the bottom plate 12, and then inserts the pins into the slots 15 of the bottom plate 12. The pins on both sides are respectively located on both sides of the upper seat 18, and the redundant parts below the lower seat 19 are cut off. Then, the first cylinder 16 is relied on to drive the cutting scissors 17 to move, so as to cut off the redundant pins on the coil. During the use process, the staff can rotate the screw rod 14 to drive the bottom plate 12 to move up and down, thereby adjusting the distance between the coil and the lower seat 19, and correspondingly adjusting the cutting length of the pins, so as to improve the applicable range and facilitate meeting the requirements for pins of different lengths. The coil is placed into the coil groove 22 above the fixed seat 21 from above. The coil groove 22 can position and provide a certain fixed support for the coil. The pins of the coil are inserted from the bottom opening. By relying on the cooperation of multiple vertical rods 31 and sliding sleeves 32, the up and down movement of the bottom plate 12 can be guided, thereby improving the stability of its movement, and further facilitating ensuring the cutting accuracy and stability. By relying on the provision of the second cylinder 41, the pushing frame 42 can be driven to move, so as to drive the sliding seat 44 to approach or move away from each other through two connecting rods 43. The movement of the sliding seat 44 will drive the clamping rod 45 to move. The clamping rod 45 can fix the pins from both sides. And when some pins are bent, the extrusion of the clamping rod 45 can play a certain role in straightening, which is convenient for cutting and improving the cutting accuracy. When the sliding seat 44 is moving, the sliding seat 44 will slide correspondingly on the slide rail 5. Therefore, the movement of the sliding seat 44 and the clamping rod 45 can be positioned and guided, thereby improving the stability of the movement of the clamping rod 45 and facilitating maintaining the clamping effect on the pins. Due to the provision of the connecting groove 6, it serves to shield the connection between the upper seat 18 and the lower seat 19, thereby reducing the extrusion of the clamping rod 45 and preventing the pins from being completely embedded into the gap between the upper seat 18 and the lower seat 19.
