[0023] Working principle and advantages of the present invention: When the steel cutting equipment for producing aircraft seat springs is used, the working process is as follows: like Figures 1 to 4 As shown, the end of the material for making the spring passes through the middle position of the two groove rollers, and passes through the second sleeve 35 and the first sleeve 18 in sequence, so that the end is located in the grinding cone 19 and buckles against the inner wall of the grinding cone 19, and the motor 10 is started by the controller, so that the motor 10 drives the shaft 11 to rotate, so that the shaft 11 synchronously drives the two worms 12 to rotate, and then the two worms 12 drive the two worm wheels 13 to perform synchronous rotational motion in opposite directions, so that the two worm wheels 13 drive the tool holder 15 to reciprocate up and down through the two connecting rods 14, so that the tool holder 15 synchronously drives the cutter 16 to reciprocate up and down, and then the cutter 16 cuts the material.

[0024] As described above, after the cutter 16 cuts the material, the two worm gears 13 drive the tool holder 15 and the cutter 16 to move upward through the two connecting rods 14, and at the same time, the tool holder 15 synchronously drives the lifting rod 22 to move upward, so that the lifting rod 22 drives the pipe shaft 23 and the gear 1 24 to move upward. When the cutter 16 is higher than the material position, the gear 1 24 is just meshed with the tooth column 25. Since the shaft rod 11 rotates and the tooth column 25 is driven to rotate synchronously through the bevel gear set 1 26, the tooth column 25 drives the pipe shaft 23 to rotate through the gear 1 24, so that the pipe shaft 23 synchronously drives the polygonal rod 36 to rotate, so that the polygonal rod 36 drives the corresponding grooved roller to rotate through the bevel gear set 2 39, so that the two grooved rollers drive the material to be transported in the direction of the grinding cone 19, and when the cutter 16 is higher than the material position, the gear 1 24 is just meshed with the tooth column 25. When the spring is set, the worm gear 13 drives the trigger block 42 to contact the touch switch 1 21, so that the touch switch 1 21 transmits the contact signal of the trigger block 42 to the controller, and the controller controls the cylinder 28 to contract, so that the cylinder 28 applies a pulling force to the connection between the connecting rod 29 and the connecting rod 30, so that the connecting rod 29 drives the slider 33 to move downward through the push rod 31, and then the slider 33 drives the right end of the cutting table 17 to rotate downward around the upper end of the bracket 2 3 through the slide rail 32, so that the cut spring blank slides onto the belt conveyor 5 and is output, realizing automatic discharge after cutting, and when the outer wall of the cylinder 28 contacts the touch switch 2 34, the touch switch 2 34 transmits the contact signal of the outer wall of the cylinder 28 to the controller, and the controller controls the cylinder 28 to extend. , so that the cylinder 28 applies a thrust to the connection between the second connecting rod 29 and the third connecting rod 30, so that the second connecting rod 29 drives the slider 33 to move upward through the push rod 31, and then the slider 33 drives the right end of the cutting table 17 to rotate upward around the upper end of the bracket 2 3 and reset through the slide rail 32. When the second connecting rod 29 and the third connecting rod 30 are in a straight line and fit with the bracket 3 4, the upper surface of the cutting table 17 is flush with the upper surface of the feeding table 6, and when the second connecting rod 29 and the third connecting rod 30 are in a straight line and fit with the bracket 3 4, the material conveying of the feeding roller group 37 has not yet reached the card sleeve 18. With the rotation of the worm gear 13, the two worm gears 13 drive the tool holder 15 and the cutting knife 16 at its lower end to rise to the highest point through the two connecting rods 14, and then change direction and move downward, and the tool holder 1 5 moves downward, and at the same time, the pipe shaft 23 and the gear 1 24 are driven downward by the lifting rod 22. When the cutter 16 is about to cut the material, the gear 1 24 is disengaged from the tooth column 25, so that the feeding roller group 37 stops feeding, and at this time, the end of the material just contacts the inner wall of the grinding cone 19. As the shaft 11 rotates and the grinding cone 19 is driven to rotate by the pulley assembly 20, the grinding cone 19 grinds the end of the material, thereby removing the burrs generated by cutting, avoiding the workers from scratching their hands during operation, and the grinding cone 19 plays a role of limiting, avoiding the cut blank from sliding off the left end of the cutting table 17, ensuring that the cut blank can slide off from the right end when the cutting table 17 is tilted. After the material is cut, with the rotation of the worm gear 13,The two worm gears 13 drive the cutter frame 15 and the cutter 16 at the lower end thereof through the two connecting rods 14 to change direction and move up again after cutting the material, and the cycle repeats to realize automatic cutting, discharging and feeding of the material, which greatly improves the degree of automation, improves work efficiency and reduces labor intensity.
