[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 2 The iron core cutting device includes a frame 1, a conveying roller 2 is provided on the front side of the frame 1, and two groups of conveying rollers 2 are provided, which cooperate with each other. At the same time, a track frame 3 is fixed to the middle of the frame 1, and a clamping block 4 and a clamping block 2 5 are symmetrically slid on the track frame 3, and clamps are opened on the sides close to each other, and the clamps are directly opposite to the centers of the two groups of conveying rollers 2. The iron core is conveyed to the clamps by the two groups of conveying rollers 2, and the end face of the iron core is in contact with the rear wall of the track frame 3. At the same time, a movable plate 7 is slid on the rear side of the frame 1, and a support tube 8 is fixed on the movable plate 7. The support tube 8 is located at the clamping position. Between block 1 4 and clamping block 2 5, and on both sides of the movable plate 7, there are pushing pieces 9 symmetrically. When the movable plate 7 approaches the track frame 3, the pushing pieces 9 push the clamping block 1 4 and the clamping block 2 5 to approach each other to clamp the iron core. At the same time, the movable plate 7 also drives the support tube 8 to extend from the insertion hole 31 opened on the rear wall of the track frame 3 and insert into the inner cavity of the iron core. The support tube 8 is used to fit the inner cavity of the iron core for support. A cutting assembly 10 is provided on the frame 1 near the front side of the track frame 3. After the iron core is clamped and supported, the cutting device is used to cut the iron core to a fixed length near the front end of the support tube 8;

[0024] A screw rod 11 is rotatably mounted on the frame 1, and the movable plate 7 is sleeved on the screw rod 11 through a threaded hole. At the same time, a motor connected to the screw rod 11 is fixed in the frame 1, and a group of power equipment including the motor is used to synchronize the clamping and supporting actions of the iron core.

[0025] See also Figure 2-Figure 5 , iron core cutting device, the rear ends of the two groups of pushing members 9 are close to each other, and the front ends are away from each other. The clamping block 4 and the clamping block 2 5 are both provided with an oblique hole groove 6. The two groups of pushing members 9 slide through the oblique hole groove 6 on the clamping block 4 and the oblique hole groove 6 on the clamping block 2 5 respectively. The arrangement of the pushing members 9 makes it possible for the movable plate 7 to approach the track frame 3, drive the clamping block 1 4 and the clamping block 2 5 to approach each other, and when the movable plate 7 is away from the track frame 3, drive the clamping block 1 4 and the clamping block 2 5 to move away from each other.

[0026] See also Figure 1-Figure 2 , iron core cutting device, a notch 33 is opened in the middle bottom wall of the track frame 3. After the iron core is cut once, the movable plate 7 moves backward to realize that the clamping block 1 4 and the clamping block 2 5 move away from each other to release the clamping state of the iron core, and at the same time, the support tube 8 moves backward to separate from the iron core. At this time, the iron core that has lost its support falls from the notch 33 to the conveying device located below, and is sequentially conveyed to the subsequent processing process.

[0027] See also Figure 1 , the core cutting device, the cutting assembly 10 includes a telescopic rod 101 fixed to the frame 1 and a mounting frame 103 fixed to the telescopic end of the telescopic rod 101, and a cutter 102 is fixedly installed on the mounting frame 103;

The gas blocked by the cutting blade during cutting can flow back out from the socket 31.
