Description

Technical Field

[0001] The utility model relates to the technical field of spring processing and production, in particular to a special tool for a spring machine. Background Art

[0002] A spring machine is a mechanical device specially used for producing springs. A spring machine is usually composed of different components, including a spring wire conveying system, a bending forming system, etc. The spring machine processes metal wire or strip steel into springs of various shapes and specifications for use in various industrial fields.

Falling and bending may cause inaccurate spring dimensions and affect the function and reliability of the spring. Falling and bending of the spring may cause the originally designed cutting position to shift, affecting the accuracy of cutting, which may cause inaccurate cutting position or skewed cutting.

One end of the electric push rod 18 is movably connected to the lower end of the rotating plate 17, and the other end of the electric push rod 18 is movably connected to the inner side surface of the bracket 9. The electric push rod 18 is used to drive the fixed component 8 to achieve angular rotation.

The electric push rod 18 is reset so that the fixed component 8 returns to the state facing the discharge port 6. A rotating motor 19 is fixedly connected to the surface of one side of the rotating plate 17.

[0033] A movable frame 25 is movably connected to the surface of one side of the movable block 21, and one end of the movable frame 25 is movably connected to one end of the fixed block 22. Four movable frames 25 are arranged and distributed in a circular array. A limiting block 24 is fixedly connected to the surface of one side of the fixed block 22. The limiting block 24 is arranged on the inner side of the movable frame 25. The limiting block 24 limits one end of the movable frame 25 to prevent the movable angle from being too large to affect the use effect.

Four top plates 26 are arranged and distributed in a circular array. The top plate 26 is used to expand outward and play a role of fixing and supporting the spring from the inside of the spring.

[0036] Working principle: Please refer to Figure 1-Figure 6As shown, when the utility model is in use, the controller 4 controls the spring machine body 1, the driving mechanism 2 and the driving mechanical arm 3, so that the spring with the required parameters that meet the standards is manufactured from the discharge port 6. When the spring is manufactured from the discharge port 6, it extends to the outside of the fixed component 8. At this time, the rotating motor 19 is started, and the rotating motor 19 drives the threaded rod 20 to rotate. When the threaded rod 20 rotates, the moving block 21 is limited by the limiting rod 23 to realize the vertical movement on the threaded rod 20. When the moving block 21 at the upper end of the threaded rod 20 moves, the moving block 21 and the fixed block 22 are moved. The side of the connected movable frame 25 will expand outward, thereby driving the top plate 26 and the soft pad 27 to support the spring from the inside of the spring, but at this time it has not expanded to the extent that the four top plates 26 and the outer soft pad 27 are tightly fitted and fixed to the spring. After the spring is produced, when various parameters including the length meet the cutting conditions, the rotating motor 19 will further rotate to make the side of the movable frame 25 connected between the moving block 21 and the fixed block 22 continue to expand outward, thereby driving the top plate 26 and the soft pad 27 to fix the spring from the inside of the spring. In the structure of the fixing component 8 The center is directly opposite to the center of the discharge port 6, the shape of the barrier spring is regular, the parameters meet the standards, the quality and performance of the product are improved, and the deformation or compression of the spring caused by the bending of the spring can be effectively reduced. After being fixed, it is moved up and down by the output end of the electric lifting rod 10, and the rotating short rod 13 and the rotating long rod 14 are displaced to a certain extent, and the active points of each connection will rotate, so that the cutting blade 15 can realize a circular motion with a track as a whole. The driving motor 16 drives the cutting blade 15 to rotate, and the circular displacement of the cutting blade 15 itself is more conducive to the cutting and cutting of the spring. The electric push rod 18 is reset to return the fixed component 8 to the state facing the discharge port 6, and the same operation is repeated to cut the next spring that meets the requirements, thereby improving the overall practicality.
