Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a cutting device for spring processing applied in the field of spring production. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. Cutting devices are used in the production of springs.

[0003] However, during the production process, due to continuous operation, the cutter will continuously impact the mandrel, thereby cutting off the spring to facilitate subsequent operations on the spring. However, after multiple impacts on the mandrel, the mandrel is easily damaged, which not only affects the spring cutting effect, but also easily causes the mandrel to be scrapped, causing the staff to frequently replace the mandrel, thereby increasing production costs, reducing work efficiency, and being inconvenient for the staff to use. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that in the process of cutting the spring, the cutter continuously impacts the mandrel, which easily causes damage to the mandrel, which not only reduces the work efficiency but also increases the production cost.

[0005] In order to solve the above problems, the utility model provides a cutting device for spring processing, including an operating table, a core shaft is fixedly passed through the center of the front section of the operating table, a plurality of guide plates are fixedly connected to the front end of the operating table, a slide groove is opened at the front end of the guide plate, a mounting strip is arranged in the slide groove, the outer ring fixed sleeve of the mounting strip is provided with a fixing block, the outer end of the fixing block is fixedly connected to a fixing rod, wherein the front ends of two corresponding mounting strips are fixedly connected to a cutting knife, the front end of the operating table is also fixedly connected to a plurality of motors, the motor is located between two adjacent guide plates, the output end of the motor is fixedly connected to a circular plate, the front end of the operating table is rotatably connected to a shaft rod, the shaft rod is located on the side of the motor away from the core shaft, the outer ring of the shaft rod is fixedly connected to an adjusting handle and a crank, the end of the adjusting handle away from the shaft rod is rotatably connected to the fixing rod, and the end of the crank away from the shaft rod is rotatably connected to the front end of the circular plate.

[0006] In the above-mentioned cutting device for spring processing, the cutter does not contact the core shaft by cutting in half, and the spring is directly cut off, thereby effectively avoiding damage to the core shaft.

[0007] As a further improvement of the present application, a plurality of guide plates are distributed in a ring array with the core shaft as the axis, and the number of the guide plates is an even number.

[0008] As a further improvement of the present application, the two cutting knives are both located in front of the core shaft, and the surfaces of the two cutting knives are respectively provided with grooves and cutting blocks that cooperate with each other.

[0009] As a further improvement of the present application, the outer end of the guide plate is fixedly connected to two positioning rods, the outer end of the positioning rod is fixedly connected to a positioning plate, the inner end of the positioning plate is fixedly connected to two guide rods, the inner end of the guide rod passes through the mounting bar and is fixedly connected to a limiting plate, and the limiting plate is located in the slide groove.

[0010] As another improvement of the present application, two fixing grooves are provided at the front end of the operating table, and rubber pistons are provided in the fixing grooves. The front ends of the rubber pistons are fixedly connected to support rods, and the front ends of the two support rods are fixedly connected to guide plates.

[0011] As another improvement supplement of the present application, the guide plate is in an eight-shaped shape and is arranged at an angle, and the distance between the upper end of the guide plate and the operating table is smaller than the distance between the lower end and the operating table.

[0012] To sum up, in actual application, the starting motor drives the circular plate to rotate clockwise at an appropriate angle, so that the crank moves inward, thereby driving the shaft rod to rotate, so that the adjusting handle rotates in a circle with the shaft rod, driving the fixed rod to move outward, thereby causing the mounting bar to move outward, and the cutter also moves outward accordingly. After the spring is formed, the starting motor is reversed to reset the circular plate, so that the two cutters are reset and move toward the core shaft at the same time to cut off the spring, so that the cutter can cut the spring without contacting the core shaft, thereby effectively reducing the damage rate of the core shaft and reducing production costs.

[0025] Figure 3 It is shown that: a plurality of motors 12 are also fixedly connected to the front end of the operating platform 1, and the motor 12 is located between two adjacent guide plates 2. A circular plate 13 is fixedly connected to the output end of the motor 12. A shaft rod 14 is rotatably connected to the front end of the operating platform 1. The shaft rod 14 is located on the side of the motor 12 away from the core shaft 17. An adjusting handle 15 and a crank 16 are fixedly connected to the outer ring of the shaft rod 14. One end of the adjusting handle 15 away from the shaft rod 14 is rotatably connected to the fixed rod 11, and one end of the crank 16 away from the shaft rod 14 is rotatably connected to the front end of the circular plate 13. By starting the motor 12 to drive the circular plate 13 to rotate, the crank 16 moves, and the adjusting handle 15 moves, thereby driving the fixed rod 11 to move inward and outward.

[0026] Figure 4 and Figure 5It is shown that: the outer end of the guide plate 2 is fixedly connected to two positioning rods 4, the outer end of the positioning rod 4 is fixedly connected to a positioning plate 5, the inner end of the positioning plate 5 is fixedly connected to two guide rods 7, the guide rods 7 can be used to limit the mounting strip 9 so that the mounting strip 9 does not shift during the movement, the inner end of the guide rod 7 passes through the mounting strip 9 and is fixedly connected to a limiting plate 8, and the limiting plate 8 is located in the slide groove 3.

[0027] The starting motor 12 drives the circular plate 13 to rotate clockwise by an appropriate angle, so that the crank 16 moves inward, thereby driving the shaft 14 to rotate, and the adjusting handle 15 rotates in a circle with the shaft 14, driving the fixing rod 11 to move outward, so that the mounting bar 9 moves outward, and the cutting knife 6 also moves outward accordingly.
