Description

Technical Field

[0001] This utility model relates to the technical field of steel plate cutting devices, specifically a cutting device for steel plate springs. Background Technology

[0002] Leaf springs are the most widely used elastic element in automotive suspensions. They are composed of several alloy spring leaves of equal width but unequal length, forming an elastic beam of approximately equal strength. Due to their excellent load-bearing and shock-absorbing capabilities, leaf springs are widely used in automobile manufacturing, playing an important role in automobiles and increasing driver comfort and vehicle lifespan.

[0003] In the manufacturing process of leaf springs, leaf springs need to be cut. During cutting, the leaf springs need to be fixed to prevent displacement of the leaf spring position, which would affect the cutting accuracy. However, the existing leaf spring cutting devices use overly simple methods to fix the leaf springs, resulting in low stability during cutting and an inability to fix leaf springs of different thicknesses and specifications. This has limitations and poor practicality. To address these issues, the inventor proposes a leaf spring cutting device to solve the problems mentioned above. Utility Model Content

A crank handle 13 is fixedly mounted at one end of the rotating shaft 12. First, the steel plate to be cut is placed on the two sliding plates 7, so that the cutting point of the steel plate is located in the middle of the operating table 1. Then, the position of the sliding rod 9 is adjusted according to the length of the steel plate. Next, according to the thickness of the steel plate, the crank handle 13 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the first bevel gear 21 to rotate, the first bevel gear 21 drives the second bevel gear 22 to rotate, and the second bevel gear 22 drives the lead screw 11 to rotate. The lead screw 11 drives the clamping plate 10 to slide down, so that the clamping plate 10 on the sliding rod 9 clamps and fixes both ends of the steel plate. The clamping plate 10 on the fixing rod 8 can clamp and fix both sides of the cutting point of the steel plate, thereby improving the stability of the steel plate during cutting. Then, the two sliding plates 7 are moved synchronously, and the cutting blade 5 cuts the steel plate on the sliding plates 7.

[0021] Both sliding plates 7 are provided with second sliding grooves 19, and sliding rods 9 are slidably installed in the corresponding second sliding grooves 19. Both second sliding grooves 19 are rotatably installed with lead screws 18, and the lead screws 18 are threaded into the corresponding sliding rods 9. One end of each lead screw 18 is fixedly installed with a turntable 14.

[0022] By adopting the above technical solution, the turntable 14 drives the lead screw 18 to rotate, and the lead screw 18 drives the sliding rod 9 to move and adjust within the second slide groove 19.

A forward and reverse motor 15 is fixedly installed at one end of the operating table 1, and the output end of the forward and reverse motor 15 is fixedly connected to one end of the drive shaft 16.

[0024] By adopting the above technical solution, the forward and reverse motor 15 drives the drive shaft 16 to rotate, the drive shaft 16 drives the two first worm gears 20 to rotate synchronously in the same direction, the two first worm gears 20 drive the two first worm wheels 17 to rotate synchronously in the same direction, the two first worm wheels 17 drive the two threaded rods 4 to rotate synchronously in the same direction, and the two threaded rods 4 drive the two sliding plates 7 to move synchronously.

[0027] Working Principle: In use, the steel plate to be cut is first placed on two sliding plates 7, with the cutting point of the steel plate located in the center of the operating table 1. Then, based on the length of the steel plate, the turntable 14 drives the lead screw 18 to rotate. The lead screw 18 drives the sliding rod 9 to move and adjust its position within the second slide groove 19. Next, based on the thickness of the steel plate, the crank handle 13 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the first bevel gear 21 to rotate, which in turn drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the lead screw 11 to rotate, and the lead screw 11 causes the clamping plate 10 to slide and descend. The clamping plate 10 on the sliding rod 9 clamps and fixes both ends of the steel plate. The clamping plate 10 on the fixing rod 8 can clamp and fix both sides of the steel plate at the cutting point, thereby improving the stability of the steel plate during cutting. Then, the forward and reverse motor 15 drives the drive shaft 16 to rotate. The drive shaft 16 drives the two first worm gears 20 to rotate synchronously in the same direction. The two first worm gears 20 drive the two first worm wheels 17 to rotate synchronously in the same direction.
